Cancer Vaccine Has Been Approved For Human Trials fact about this
 
03:20
Cancer Vaccine Has Been Approved For Human Researchers at Stanford University have developed a compound that when injected into a tumor destroys it along with all the other cancerous masses present in the body. The combination of two agents that stimulate the immune system sparked a body-wide reaction in mice, destroying cancer cells both near and very far from the initial injection point. The success of the treatment, which worked for different types of cancer, means that human trials will be starting soon. When people get cancer, immune cells can recognize and attack specific proteins present in the tumors, but as the cancer grows it suppresses the immune system. Some cancers even trick it into helping rather than harming them. author of the study, noted: “I don’t think there’s a limit to the type of tumor we could potentially treat, as long as it has been infiltrated by the immune system.” ====================================== TO_OWNERS_AND_COPYRIGHT: This channel is created to promote the best informative videos releated Health Technology Science nature performers,and producers.

Lab Grown Meat Could Be On Sale By End Of 2018
 
03:25
Lab Grown Meat Could Be On Sale By End Of 2018 According to experts, cultured tissue, harvested without harming and killing any animals could allow scientists to grow meals in labs with just a handful of starter cells. In fact, one manufacturer has gone on to claim that meat grown in a laboratory could be on restaurant menus by the end of the year. In vitro animal products, sometimes referred to as “clean meat”, are made from stem cells harvested via biopsy from living livestock, which are then grown in a lab over a number of weeks. Some environmentalists believe the process could be the key to reducing global warming, with one study predicting it could lower harmful greenhouse emissions by 96 per cent. According to Josh Tetrick, CEO of clean meat manufacturer JUST, the first products could be available for human consumption within months. Speaking to CNN, he said that chicken nuggets, sausage and foie gras created using the technique could be served in restaurants in the US and Asia "before the end of 2018.” However, a reluctance to diverge from traditional farmed meat still represent considerable hurdles for the clean meat industry. The worry is shared by Mosa Meat, whose lab based at Maastricht University in the Netherlands, was responsible for creating the world’s first cultured hamburger. Professor Mark Post, the company’s chief scientific officer said the regulatory approval process could delay samples being distributed to suppliers by years. He gave a time frame of three years before the company could sell its first product to the mass market. But one recent study revealed one third of Americans would be willing to eat clean meat regularly or as a replacement for farmed meat. However, to reach that point, companies will have to bring down the cost of mass production. Animal rights charity PETA has been investing in in vitro meat research for the past six years and had in 2014, offered a $1 million (£725,000) reward to the first scientist to produce and bring to market in vitro chicken meat. ====================================== TO_OWNERS_AND_COPYRIGHT: This channel is created to promote the best informative videos releated Health Technology Science nature performers,and producers.

Playing A Musical Instrument Makes You Smarter
 
03:08
Playing A Musical Instrument Makes You Smarter. New research suggests that regularly playing an instrument changes the shape and power of the brain and may be used in therapy to improve cognitive skills. It can even increase IQ by seven points in both children and adults, according to researchers. Experts said there is growing evidence that musicians have structurally and functionally different brains compared with non-musicians - in particular, the areas of the brain used in processing and playing music. These parts of the brain that control motor skills, hearing, storing audio information and memory become larger and more active when a person learns how to play an instrument and can apparently improve day to day actions such as being alert, planning and emotional perception. Lutz Jäncke, a psychologist at the University of Zurich, said: "Learning to play a musical instrument has definite benefits and can increase IQ by seven points, in both children and adults. "We found that even in people over the age of 65 after four or five months of playing a instrument for an hour a week there were strong changes in the brain. "The parts of the brain that control hearing, memory, and the part that controls the hands among others, all become more active. Essentially the architecture of the brain changes. "For children especially we found that learning to play the piano for instance teaches them to be more self-disciplined, more attentive and better at planning. All of these things are very important for academic performance, so can therefore make a child brighter. "Of course music isn't the only answer, but I do believe that it should be used in addition to other things." Mr Jäncke also said that music can also make it easier to learn foreign languages and become more perceptive in interpreting the emotions of others. He added: "When you play a musical instrument you have to learn about tone and about scores and your ability to store audio information becomes better. "So not only does this make it easier to pick up other languages and have a better verbal memory in your own language, we have also seen that musicians are able to pick out exactly what others are feeling just on the tone of their voices. Empathy, disappointment, that kind of thing. "If music has such a strong influence on brain plasticity this raises the question of whether this effect can be used to enhance cognitive performance. "Several studies indeed show that musical practice increases memory and language skills, and I suggest expanding this field. "Hopefully, the current trend in the use of musicians as a model for brain plasticity will continue ... and extend to the field of neuropsychological rehabilitation." ====================================== TO_OWNERS_AND_COPYRIGHT: This channel is created to promote the best informative videos releated Health Technology Science nature performers,and producers.

New Drug Could Treat Paralysis and Fix Injured Spinal Cords
 
03:30
New Drug Could Treat Paralysis and Fix Injured Spinal Cords Most people with spinal cord injuries are paralyzed below the injury site, even if the cord is only partially severed. Researchers don’t know why the nerve pathways that are still intact also stop working. A new study provides a promising answer, and a path to restoring movement. Researchers treated mice with partially severed spinal cords with a compound called CLP209. The drug was administered over eight to ten weeks. About 80 percent of the injured mice regained their ability to take steps. “Stepping is a first step towards motor functional recovery in animals, and perhaps humans,”Many animal studies attempting to repair spinal cord damage have focused on getting nerve fibers to regenerate, or new ones to grow out of remaining healthy fibers. He and other researchers have achieved this, but they didn’t see the corresponding improvements in motor function they had hoped for. He and his coauthors decided to try a different approach. They were inspired by treatments that stimulate the space around injured patients’ spinal cord with electric currents. When combined with rehabilitation training, this stimulation is the only treatment for spinal cord injury patients known to be effective. "However, in these studies, when you turn off the stimulation, the effect is gone,” says He. The researchers set out to see if they could use drugs to mimic the stimulation caused by electric currents, so the effect would be longer-lasting. They tested several compounds known to alter the excitability of neurons. A small molecule called CLP209 worked best, and the treated mice remained more mobile than untreated mice up to two weeks after treatment stopped.After a spinal cord injury, neurons that send signals inhibiting movement don’t produce enough of the KCC2 protein. As a result of this deficit, they don’t receive instructions from the brain to stop firing, and the overall spinal circuit is overwhelmed with inhibitory signals. When the mice were treated with CLP290, the drug restored KCC2 levels, the brain’s commands to stop firing got through to inhibitory neurons, and signals resulting in movement were no longer overpowered. "Too much excitation is not good, and too much inhibition is not good either,” says He. “You really need to get a balance. This hasn't been demonstrated in a rigorous way in spinal cord injury before. #spinal_cord_injury #inside_human_channel #treatment_of_injured_spinal_cord ====================================== TO_OWNERS_AND_COPYRIGHT: This channel is created to promote the best informative videos releated Health Technology Science nature performers,and producers.

Scientists Have Created Biological Computers Inside Living Cells
 
03:30
Scientists Have Created Biological Computers Inside Living Cells We’ve developed [a biological computer] that controls how cells behave,” says Alexander Green, an engineer at Arizona State University, who developed the technology with colleagues at Harvard University. “The [bacterial] cells go about their normal business, replicating and sensing what’s going on in their environments, but they’ve also got this computational machinery in them that we’ve instructed them to [synthesise],” he says, and the new biological circuit works just like a digital one, it receives an input and makes a logic-based decision, using AND, OR, and NOT operations, but instead of the inputs and outputs being voltage signals, they are the presence or absence of specific chemicals or proteins. The process begins with the design of a DNA strand that codes for all the logic the system will need. The researchers then inserted the synthesised DNA into E. coli bacteria as part of a plasmid, which is a ring of DNA that can replicate itself as it floats around in the cell, that served as a template for the biological computer’s machinery. The cell’s molecular machinery then translated the DNA into RNA, essentially copying the DNA code onto a different molecule, which could then be used by the cell. This RNA then linked up with the cell’s ribosome and instructed it to produce a protein specified in the RNA’s code. But here’s where the system behaves like a computer though rather than just a genetically engineered organism – the RNA only does its job when it receives an input that activates it. That’s because the engineered RNA contains codes not just for a protein, but also for logic functions. The logic portions must receive the right inputs in order to activate the RNA in a way that allows the ribosome to use it to produce the circuit’s output, or in this case a protein that glows. “Those switches are kind of the equivalent of your first transistors,” says Green, “they are devices we can build into more complex things.” Green’s team was able to arrange multiple biological transistors, which they call “toehold switches,” together, that then formed what the researchers called the “gate RNA”, which is a kind of molecular logic circuit. The inputs, in Green’s demonstration, were strands of RNA added to the cells after the plasmid containing the “gate RNA” code has already been inserted. These input RNAs paired up with those of the codes of the ribocomputer’s gate RNA. A match between the input RNA and the gate RNA freed the strand so that when it encountered a ribosome, it could tell the cellular machinery to produce the florescence protein, which was easy to see when the system worked, because the E. coli lit up. ====================================== TO_OWNERS_AND_COPYRIGHT: This channel is created to promote the best informative videos releated Health Technology Science nature performers,and producers.

Belly Fat is Very Dangerous To Your Health
 
03:21
You’ve probably heard that your belly is the most dangerous place to carry excess fat because of its link to health risks. It’s true, and now new research from the Mayo Clinic reveals that being normal weight with excess belly fat is even more risky than simply qualifying as obese. In other words, your waistline matters—a lot. The study looked at a representative sample of the US population, which included more than 12,000 subjects ages 18 years and older. Through surveys, various facts were collected, including height, weight, waist and hip measurements, socioeconomic status, illnesses, and lab tests. That baseline data was matched to the National Death Index about 14 years later, and people with chronic obstructive pulmonary disease and cancer were excluded from the analysis. Scientists found that subjects with normal BMIs who were apple shaped (a high waist-to-hip ratio) were more likely to die from any cause, even compared to those who were obese. In addition, this group was 2.75 times more likely to die from heart disease and twice as likely to die from any cause compared with those who had a normal BMI and a healthy waist-to-hip ratio. The news is scary, but if you’re worried about your expanding waistline, don’t panic. First, consider which type of belly fat you’re carrying. Researchers believe the risks found in this study are tied to internal belly fat, also called visceral fat. Subcutaneous belly fat, the squishy, squeezable kind just under the surface of your skin, isn’t considered as hazardous. Visceral fat on the other hand is the deep, internal belly fat under your abdominal muscles that accumulates around your organs. It doesn’t jiggle when you walk, and it’s more dangerous because it’s associated with an increased risk of a number of health problems, including heart disease, type 2 diabetes, dementia, high blood pressure, and some cancers. If you think you may be carrying more visceral fat, there are steps you can take to reduce it. In another recent study, Wake Forest researchers found that two habits stood out in reducing belly fat accumulation: eating more soluble fiber and engaging in moderate activity. Among more than 1,000 people studied, each 10-gram increase in soluble fiber consumed per day resulted in a 4 percent reduction in visceral fat over five years. And being regularly moderately active resulted in more than a 7 percent decrease in visceral fat build up over the same time period. There are lots of resources here on Shape.com to help you be more active. As for soluble fiber, that’s the soft sticky kind found in oats (if you’ve ever stirred oatmeal you’ve probably see that stickiness). Other good sources are fruits, veggies, beans, and lentils. Here are five foods, which can reasonably be consumed in one day, that add up to an extra 10 grams of soluble fiber: 2 tablespoons flax seeds (2.2 g), 1 cup cooked Brussels sprouts (4 g), ½ cup black beans (1.4 g), 1 small orange (1.8 g), 1 (7”) raw carrot (1.1 g). And there are other ways to lower your risk. Check out some of my previous posts, which include belly-fat fighting strategies like eating more raw foods, choosing good fats, reaching for more berries, and considering certain vitamins.

Leg Exercise is Important to Your Brain Health
 
03:21
Leg Exercise is Important to Your Brain Health The research shows that using the legs, particularly in weight-bearing exercise, sends signals to the brain that are vital for the production of healthy neural cells, essential for the brain and nervous system. ... "Neurological health is not a one-way street with the brain telling the muscles 'lift,' 'walk,' and so on Groundbreaking research shows that neurological health depends as much on signals sent by the body's large, leg muscles to the brain as it does on directives from the brain to the muscles. Published today in Frontiers in Neuroscience, the study fundamentally alters brain and nervous system medicine -- giving doctors new clues as to why patients with motor neuron disease, multiple sclerosis, spinal muscular atrophy and other neurological diseases often rapidly decline when their movement becomes limited. credit goes to https://www.youtube.com/user/hashemalghaili subscribe our channel subscribe this channel https://www.youtube.com/channel/UC4GrKzQc0n-i8DsjH_ynkNA?view_as=subscriber Google plus https://plus.google.com/102332871130341184209 twitter https://twitter.com/InsideHuman2

Researchers Discover the Moment Alzheimer's disease Is Triggered
 
03:29
Researchers Discover the Moment Alzheimer's disease Is Triggered A recent study has shed promising light on a potential method to detect early Alzheimer’s and possibly treat or prevent the disease before symptoms even appear. The study concluded that a decline in glucose levels in the brain starts to occur right before the first symptoms of Alzheimer’s disease appear. Researchers at Temple University believe this discovery may lead to treatments that prevent Alzheimer’s disease from taking hold by keeping glucose levels in the brain from dropping in the first place. For years, researchers and doctors have noticed an association between declining brain glucose levels and the onset of Alzheimer’s disease. However, until now, no one had found that they are a trigger for cognitive impairments. The study was conducted on mice, and the results were published in the Journal of Translational Psychiatry in January. As anticipated, mice that were deprived of glucose in their brains showed signs of mental decline that indicated a breakdown of communication between neurons. The same mice also performed worse in maze memory tests than the control mice who were not deprived of glucose. Because cognitive decline is impacted by glucose levels, researchers suggest that a protein known as “p38,” which regulates glucose in the body, could possibly have a role in preventing Alzheimer’s. Early tests with p38 show that the anti-inflammatory properties of the protein may reduce the formation of plaques in the brain that are associated with dementia. All tests conducted by the team at Temple University were performed on mice, and much more research and development is needed before human trials begin; however, these scientists are encouraged. Lead researcher, Dr. Domenico Praticò, called the findings “extremely exciting.” ====================================== TO_OWNERS_AND_COPYRIGHT: This channel is created to promote the best informative videos releated Health Technology Science nature performers,and producers.

As much as 4% of your DNA is from Neanderthals
 
04:12
When our ancestors first migrated out of Africa around 70,000 years ago, they were not alone. At that time, at least two other species of hominid cousins walked the Eurasian landmass—Neanderthals and Denisovans. As our modern human ancestors migrated through Eurasia, they encountered the Neanderthals and interbred. Because of this, a small amount of Neanderthal DNA was introduced into the modern human gene pool. Everyone living outside of Africa today has a small amount of Neanderthal in them, carried as a living relic of these ancient encounters. A team of scientists comparing the full genomes of the two species concluded that most Europeans and Asians have approximately 2 percent Neanderthal DNA. Indigenous sub-Saharan Africans have none, or very little Neanderthal DNA because their ancestors did not migrate through Eurasia. On one level, it’s not surprising that modern humans were able to interbreed with their close cousins. According to one theory, Neanderthals, Denisovans, and all modern humans are all descended from the ancient human Homo heidelbergensis. Between 500,000 to 600,000 years ago, an ancestral group of H. heidelbergensis left Africa and then split shortly after. One branch ventured northwestward into West Asia and Europe and became the Neanderthals. The other branch moved east, becoming Denisovans. By 250,000 years ago H. heidelbergensis in Africa had become Homo sapiens. Our modern human ancestors did not begin their own exodus from Africa until about 70,000 years ago, when they expanded into Eurasia and encountered their ancient cousins. The revelation that our ancient ancestors mated with one another could help explain one of the great mysteries in anthropology: Why did the Neanderthals disappear? After first venturing out of Africa, Neanderthals thrived in Europe for several hundred thousand years. But they mysteriously died out about 30,000 years ago, roughly around the same time that modern humans arrived in Europe. Some scientists have suggested modern humans out-competed or outright killed the Neanderthals. But the new genetic evidence provides support for another theory: Perhaps our ancestors made love, not war, with their European cousins, and the Neanderthal lineage disappeared because it was absorbed into the much larger human population. Even though Neanderthals and Denisovans are both extinct, modern humanity may owe them a debt of gratitude. A 2011 study by Stanford University researchers concluded that many of us carry ancient variants of immune system genes involved in destroying pathogens that arose after we left Africa. One possibility is that these gene variants came from other archaic humans. {====================================== TO_OWNERS_AND_COPYRIGHT: This channel is created to promote the best informative videos releated Health Technology Science nature performers,and producers.

The World's First Human Trial Uses Stem Cells To Treat Parkinson's
 
03:27
The World's First Human Trial Uses Stem Cells To Treat Parkinson's Japanese researchers on Monday (Jul 30) announced the world's first human trial using a kind of stem cell to treat Parkinson's disease, building on earlier animal trials. The research team at Kyoto University plans to inject five million induced Pluripotent Stem (iPS) cells - which have the potential to develop into any cell in the body - into patient brains, the university said in a press release.The iPS cells from healthy donors will be developed into dopamine-producing brain cells, which are no longer present in people with Parkinson's disease. Parkinson's disease is a chronic, degenerative neurological disorder that affects the body's motor system, often causing shaking and other difficulties in movement. Worldwide, about 10 million people have the illness, according to the Parkinson's Disease Foundation. Currently available therapies "improve symptoms without slowing or halting the disease progression," the foundation says.But the new research aims to actively reverse the disease. The clinical test with seven participants aged between 50 and 69 will begin on Wednesday. The university will monitor the conditions of the patients for two years after the operation. The human trial comes after an earlier trial involving monkeys. Researchers announced last year that primates with Parkinson's symptoms regained significant mobility after iPS cells were inserted into their brains. They also confirmed that the iPS cells had not transformed into tumors during the two years after the implant. iPS cells are created by stimulating mature, already specialised, cells back into a juvenile state - basically cloning without the need for an embryo. These can be derived from the patient, making them less likely to be rejected, while also sidestepping ethical qualms about taking cells from embryos. The cells can be transformed into a range of different types of cells, and their use is a key sector of medical research. In 2014, Riken, a Japanese government-backed research institution, carried out the world's first surgery to implant iPS cells to treat a patient with age-related macular degeneration (AMD), a common medical condition that can lead to blindness in older people. Osaka University is also planning a clinical test to treat heart failure by using a heart muscle cell sheet created from iPS cells. In the US, scientists from Duke University said in January they had managed for the first time to grow functioning human muscle from iPS cells in the lab. #parkinsons_disease #inside_human_channel #Stem_Cells_To_Treat_Parkinson's #hashem_al_ghaili_videos ====================================== TO_OWNERS_AND_COPYRIGHT: This channel is created to promote the best informative videos releated Health Technology Science nature performers,and producers.

More Than 1000 Genes Have Been Linked To Intelligence
 
03:20
More Than 1000 Genes Have Been Linked To Intelligence A large-scale genetic study has identified a total of 1,016 genes that are associated with intelligence, of which 939 added genes were previously unknown to science. Using a breakthrough statistical method to conduct their study, the international team of researchers found that the genes attributed to high cognitive abilities were also linked to genes responsible for longevity. This insight suggests that intelligent people may live longer than most of their counterparts. More so, intelligent people were seemingly protected from genes that bring Alzheimer's disease, ADHD, and schizophrenia. On the other hand, the genes responsible for intelligence are also linked to genes that bring an increased risk of autism. Meta-analysis In 269,867 Individuals The researchers, headed by Danielle Posthuma, a statistical geneticist from Vrije University in Amsterdam, used a method called MAGMA to perform the genome-wide association study or GWAS of 269,867 people. The participants answered a series of neurocognitive tests that served as an assessment of their intelligence. The scores from the tests were compared to the participants' DNAs that were analyzed through a process called single nucleotide polymorphisms. This process involved observing the actual gene mutations that are correlated with superior intelligence. The team was able to detect more than 9 million mutations from the DNA samples of the participants. They also identified 205 regions in DNA, and, as mentioned, a total of 1,016 specific genes related to intelligence. The study noted that 77 of these genes had already been previously identified prior to the present study. The study also said the majority of the genes for intelligence were found to be located in the "medium spiny neurons" which forms part of the brain's basal ganglia. The latter is comprised of clusters of neurons located deep within the portion of the brain where learning, cognition, and emotion are being processed. Practical Applications Of The Study Posthuma said their findings can be significant in the diagnosis of autism, ADHD, and of people at risk of developing depression, Alzheimer's, and schizophrenia. In the future, diagnosis of such conditions may be conducted based on gene analysis. The most ideal application will be designing gene therapy treatments for these mental conditions. "These results are a major step forward in understanding the neurobiology of cognitive function as well as genetically related neurological and psychiatric disorders," the team wrote in its study published in the journal Nature Genetics on June 25. Peter Visscher, a geneticist who was not involved in the study, said the findings served as solid evidence of how several genes are working together to make people intelligent and maintain stable minds. creidit goes to https://www.youtube.com/user/hashemalghaili subscribe our channel for more update subscribe this channel https://www.youtube.com/channel/UC4GrKzQc0n-i8DsjH_ynkNA?view_as=subscriber Google plus https://plus.google.com/102332871130341184209 twitter https://twitter.com/InsideHuman2

Human Blood Cells Successfully Converted into Neurons
 
03:26
Human Blood Cells Successfully Converted into Neurons. Human immune cells in blood can be converted directly into functional neurons in the laboratory in about three weeks with the addition of just four proteins, researchers at the Stanford University School of Medicine have found. The dramatic transformation does not require the cells to first enter a state called pluripotency but instead occurs through a more direct process called transdifferentiation. The conversion occurs with relatively high efficiency — generating as many as 50,000 neurons from 1 milliliter of blood — and it can be achieved with fresh or previously frozen and stored blood samples, which vastly enhances opportunities for the study of neurological disorders such as schizophrenia and autism. “Blood is one of the easiest biological samples to obtain,” said Marius Wernig, MD, associate professor of pathology and a member of Stanford’s Institute for Stem Cell Biology and Regenerative Medicine. “Nearly every patient who walks into a hospital leaves a blood sample, and often these samples are frozen and stored for future study. This technique is a breakthrough that opens the possibility to learn about complex disease processes by studying large numbers of patients.” A paper describing the findings was published online June 4 in the Proceedings of the National Academy of Sciences. Wernig is the senior author. Former postdoctoral scholar Koji Tanabe, PhD, and graduate student Cheen Ang are the lead authors. Dogged by challenges The transdifferentiation technique was first developed in Wernig’s laboratory in 2010 when he and his colleagues showed that they could convert mouse skin cells into mouse neurons without first inducing the cells to become pluripotent — a developmentally flexible stage from which the cells can become nearly any type of tissue. They went on to show the technique could also be used on human skin and liver cells. credit goes to https://www.youtube.com/user/hashemalghaili subscribe our channel for more update subscribe this channel https://www.youtube.com/channel/UC4GrKzQc0n-i8DsjH_ynkNA?view_as=subscriber Google plus https://plus.google.com/102332871130341184209 twitter https://twitter.com/InsideHuman2

Researchers Found A New Way To Reverse Wrinkles And Hair Loss In a groundbreaking new study, scientists were able to reverse wrinkled skin and hair loss – in mice.Conducted by the University of Alabama at Birmingham and published in Cell Death & Disease, the research found a way to turn off the gene mutation that causes symptoms of ageing.During the human ageing process, our mitochondrial function declines which can cause diseases and neurological disorders as well as visible symptoms of growing older, such as wrinkling and hair loss.the scientists conducting this study activated a mutation in the mice, within four weeks they started becoming lethargic, their hair greying and falling out. After four-eight weeks their skin began wrinkling (with more severe results seen in the female mice than male ones), presenting a similar structure to human wrinkles.Then – quite astonishingly – after turning off the mutation, the hair loss and wrinkled skin began reversing and the mice returned to their original appearance, though the ageing of their organs did not. “To our knowledge, this observation is unprecedented,” Keshav Singh, professor of genetics at the University of Alabama said in a statement, Newsweek report. It suggests that the mitochondrial function plays a stronger role in skin health over that of the internal organs. The potential of this cutting-edge science for human benefit is certainly significant, though still some way off being utilised. From drug companies to cosmetic products, it could completely change the 'anti-ageing' conversation. ====================================== TO_OWNERS_AND_COPYRIGHT: This channel is created to promote the best informative videos releated Health Technology Science nature performers,and producers.

Mosquitoes Bite Some People More Than Others
 
03:21
Why do mosquitoes attack some people and not others? Lets look at what mosquitoes are looking for when they crash land on our skin. Without any hint of sexism we can say that only female mosquitoes will bite, as they need mammal blood to feed their eggs. There are 150 species in the USA alone, and they all have preferences for their ideal blood fix. Experiments have proven this; scientists have tested the preferences of various mosquito species and got varying results. Mosquitoes are choosy and they want the best for their eggs. We produce chemicals and microbes which make up our unique body odour. They know exactly the right chemical mix and its odour because this accurately represents the blood they want. They can also detect these attractive aromas up to 30 metres away! What makes up this chemical mix? Just think that we have 100 trillion microbes, which is ten times the number of human cells we possess. We have a unique microbial signature, which is mostly due to genetics. This will determine what type of bacteria we host in our gut and bodies. These microbes are an essential part of our immune system, so washing frequently is not going to do any good. It will certainly not deter the mosquitoes zooming in because their sense of smell is extremely sharp. Your blood type is another factor The mosquito is after blood, and if it smells right, you are going to be a target. In one limited experiment, it was found that mosquitoes preferred people with Type O blood twice as much as those with Type A. It is fascinating to know that in 85% of cases, you actually send a chemical signal indicating which blood type you have, which entices the mosquito. Lactic acid seems to be a definite attraction to most mosquito species. When you eat certain foods, such as cheese, soya, yogurt and pickled vegetables, and do vigorous exercise, you will have more lactic acid on your skin. That is very attractive to some mosquito species. Don’t believe all those people who say they are never bitten! The fact is that many more people are bitten by mosquitoes than you would think. It is all due to the reaction; people react in different ways to the mosquito leaving saliva when sucking their blood. This depends on environmental and allergic reactions. Many more people are bitten, but because they have no symptoms they are convinced that they are not attractive to mosquitoes. If only they knew! To sum up, genetics and our chemical/microbial mix determine whether we are going to be bitten by mosquitoes or not. There seems to be a link between these and a person’s blood type. The amount of CO2, garlic or alcohol we consume, or dark-coloured clothing, are all secondary factors, but may help in keeping mosquitoes at bay. ====================================== TO_OWNERS_AND_COPYRIGHT: This channel is created to promote the best informative videos releated Health Technology Science nature performers,and producers.

This Wireless System Can Power Devices Inside The Body

This Wireless System Can Power Devices Inside The Body Wireless system can power devices inside the body Credit: Felice Frankel, edited by MIT News A new way to power and communicate with devices implanted deep within the human body has been developed by a team from MIT and Brigham and Women's Hospital (BWH). The implants are powered by radio frequency waves, which can safely pass through human tissues. In tests in animals, the researchers showed that the waves can power devices located 10cm deep in tissue, from a distance of 1metre. If the sensors are located very close to the skin's surface, the researchers add, they can be powered from up to 38meters away. "Even though these tiny implantable devices have no batteries, we can now communicate with them from a distance outside the body," says Assistant Professor Fadel Adib from MIT. Such devices could be used to deliver drugs, monitor conditions inside the body, or treat disease by stimulating the brain with electricity or light, the researchers say. The researchers tested a prototype about the size of a grain of rice, but anticipate that it could be made even smaller. "Having the capacity to communicate with these systems without the need for a battery would be a significant advance. These devices could be compatible with sensing conditions as well as aiding in the delivery of a drug," says Assistant Professor Giovanni Traverso at BWH. In the brain, implantable electrodes that deliver an electrical current are used for a technique known as deep brain stimulation – often used to treat Parkinson's disease or epilepsy. These electrodes are currently controlled by a pacemaker-like device implanted under the skin, which could be eliminated if wireless power is used. Wireless brain implants could also help deliver light to stimulate or inhibit neuron activity through optogenetics, which so far has not been adapted for use in humans but could be useful for treating many neurological disorders. Assist Prof. Adib who envisions much smaller, battery-free devices, has been exploring the possibility of wirelessly powering implantable devices with radio waves emitted by antennas outside the body. This has been difficult to achieve because radio waves tend to dissipate as they pass through the body, so they end up being too weak to supply enough power. To overcome that, the researchers devised a system that they call "In Vivo Networking" (IVN). This system relies on an array of antennas that emit radio waves of slightly different frequencies. As the radio waves travel, they overlap and combine in different ways. At certain points, where the high points of the waves overlap, they can provide enough energy to power an implanted sensor. "We chose frequencies that are slightly different from each other, and in doing so, we know that at some point in time these are going to reach their highs at the same time. When they reach their highs at the same time, they are able to overcome the energy threshold needed to power the device," Assist Prof. Adib says. With the new system, the researchers explain that they don't need to know the exact location of the sensors in the body, as the power is transmitted over a large area. This also means that they can power multiple devices at once. At the same time that the sensors receive a burst of power, they also receive a signal telling them to relay information back to the antenna. This signal could also be used to stimulate release of a drug, a burst of electricity, or a pulse of light, the researchers add. The team is now working on making the power delivery more efficient and transferring it over greater distances. The hope is that this technology also has the potential to improve RFID applications in other areas such as inventory control, retail analytics, and smart environments, allowing for longer-distance object tracking and communication. subscribe this channel https://www.youtube.com/channel/UC4GrKzQc0n-i8DsjH_ynkNA?view_as=subscriber Google plus https://plus.google.com/102332871130341184209 twitter https://twitter.com/InsideHuman2 instagram https://www.instagram.com/insidehuman2018/?hl=en

New Treatments For Arthritis Look Promising
 
03:26
Arthritis is very common but is not well understood. Actually, “arthritis” is not a single disease; it is an informal way of referring to joint pain or joint disease. There are more than 100 different types of arthritis and related conditions. People of all ages, sexes and races can and do have arthritis, and it is the leading cause of disability in America. More than 50 million adults and 300,000 children have some type of arthritis. It is most common among women and occurs more frequently as people get older. Common arthritis joint symptoms include swelling, pain, stiffness and decreased range of motion. Symptoms may come and go. They can be mild, moderate or severe. They may stay about the same for years, but may progress or get worse over time. Severe arthritis can result in chronic pain, inability to do daily activities and make it difficult to walk or climb stairs. Arthritis can cause permanent joint changes. These changes may be visible, such as knobby finger joints, but often the damage can only be seen on X-ray. Some types of arthritis also affect the heart, eyes, lungs, kidneys and skin as well as the joints. subscribe this channel https://www.youtube.com/channel/UC4GrKzQc0n-i8DsjH_ynkNA?view_as=subscriber Google plus https://plus.google.com/102332871130341184209 twitter https://twitter.com/InsideHuman2 instagram https://www.instagram.com/insidehuman2018/?hl=en

Psychedelic Drugs May Help the Brain To Repair Itself
 
03:16
Psychedelic Drugs May Help the Brain To Repair Itself It's no surprise that psychedelic drugs such as LSD and ecstasy alter brain function, leading to the drugs' "trippy" effects and possible hallucinations. But now, researchers have shown that these drugs can also physically alter the brain, changing the structure of brain cells. The new study was done on nerve cells in lab dishes and in animals, but if the findings also hold true in humans, these drugs could have surprising benefits for patients with certain mood disorders, the researchers said. That's because, in people with depression or mood and anxiety disorders, neurons in the prefrontal cortex — an area of the brain that's important in part for controlling emotion — tend to shrivel up, said senior study author David Olson, an assistant professor of chemistry, biochemistry and molecular medicine at the University of California, Davis. What's more, the branches and dendritic spines on the neurons' branches — which they use to communicate with other neurons — tend to retract, he said. [11 Odd Facts About 'Magic' Mushrooms] In the study, published today (July 12) in the journal Cell Reports, Olson and his team found that psychodelic drugs increase the number of branches and dendritic spines on neurons, and also increase the number of synapses, or connections between neurons. "Psychedelics are able to actually [change] neuronal structure, [and] that's really important because [brain] structure controls function," Olson told Live Science. That means it's possible that these drugs could help repair brain networks in the prefrontal cortex that might be damaged in conditions like anxiety and depression, he said. To study these neuron-changing effects, the researchers first tested the effects of various psychedelic drugs on rat neurons in petri dishes. They found that most of these drugs — including LSD (lysergic acid diethylamide) and MDMA (3,4-methylenedioxy-N-methylamphetamine), the active ingredient in ecstasy — increased the number of synapses, branches and dendritic spines on the rat neurons. In the next part of the study, the researchers gave psychedelics to fruit flies and found that the number of branches in their neurons again increased with the drugs. Finally, the researchers gave rats a psychodelic drug called DMT (N,N-dimethyltryptamine). DMT is the compound responsible for the psychedelic effects of ayahuasca, an herbal tea from the Amazon. The researchersfound that, although the drug's effects didn't last long — most of the drug was eliminated from the rats' systems within a few hours — their brains continued to rewire for at least 24 hours. Olson said the findings were comparable to how a drug called ketamine, which is used primarily as an anesthetic but is gaining popularity as a means of treating depression, worked. "Ketamine is probably the state-of-the-art, fast-acting antidepressant," Olson said. "When we first started this work, there really [weren't] many options for promoting [changes to the brain's structure]. Ketamine was one of the few." Indeed, a major focus of the team's research has been to find compounds that have ketamine-like effects, to better understand the mechanism by which these drugs can change the brain, he said. Some psychedelics might have less addictive potential than ketamine, Olson added. The "slow-acting, more traditional anti-depressants … also cause structural changes in the brain," Olson said. (These include selective serotonin reuptake inhibitors, or SSRIs, such as Prozac and Zoloft.) "But we're looking for something that can cause those structural changes fast," he added. In the study, Olson's team reported that, after 24 hours, they saw structural changes in rat brains, but now they want to see if these changes actually happened quicker than that. #Psychedelic_Drugs #inside_human ====================================== TO_OWNERS_AND_COPYRIGHT: This channel is created to promote the best informative videos releated Health Technology Science nature performers,and producers.

How does human cloning work?
 
03:14
How does human cloning work? The first successful animal cloning experiment was conducted in 1996 by Ian Wilmut at the Roslin Institute in Edinburgh; the subject was a sheep. Before Wilmut, back in 1970, John Gurdon tried to clone tadpoles using the same method, but the tadpoles died. Wilmut’s cloned sheep was named Dolly. Wilmut and his colleagues took the egg (ovum) of a Scottish blackface ewe and enucleated it, meaning they removed the nucleus from the egg. Next, they transplanted the nucleus from a mammary gland cell of a Finn Dorsette sheep into the enucleated egg. The nucleus- egg combination was stimulated by electricity to fuse them together and stimulate cell division. The new cell divided and was then placed in the uterus of the blackface ewe to develop. Dolly, the baby lamb that was born, was a clone of the Finn Dorsette sheep and was white in color, even though it was carried in the womb of the black ewe. Since the breakthrough of Dolly, numerous scientists have created animal clones of pigs, mice, and even monkeys! Apart from the ethical issues involved in cloning humans, there are technological limitations as well. The process of cloning as it exists today is not foolproof. Every enucleated egg that is transplanted with a nucleus from a donor does not survive the transplantation and multiply. It can take multiple tries to make the procedure succeed. A resource of 100 ovaries can yield up to 1000 eggs, but scientists must be able to convince that many women to donate their ovaries. That is one major problem with respect to human cloning. Apart from the availability of willing hosts, other problems could easily crop up.or example, it is hard to clone birds because extracting the nucleus from bird eggs has proved to be difficult, since it is surrounded by the dense yolk. The human cloning process may involve these or many other issues that will only be known once attempts have been made. The other obstacle for attempting human cloning is an ethical one, as mentioned. Would it be right to clone humans, given the concerns of identity and privacy that are involved. subscribe this channel https://www.youtube.com/channel/UC4GrKzQc0n-i8DsjH_ynkNA?view_as=subscriber Google plus https://plus.google.com/102332871130341184209 twitter https://twitter.com/InsideHuman2 instagram https://www.instagram.com/insidehuman2018/?hl=en

Having too many deadlines destroys your productivity
 
03:09
Having too many deadlines destroys your productivity Are you a busy bee about to go ‘out of your hive’ because of the massive amount of work on your plate? Even with the influx of technology assisting our everyday activities, life just doesn’t seem to slow down. In fact, today’s virtually limitless communication methods generate additional reasons to keep our brains ticking. On top of filling in the gaps in life that were once free, digital technology is yet another distraction we add to the “busy-list”. Before taking on another task, here are a few productivity-pointers to ponder before buzzing off to your next engagement.Something fascinating happens to our brains when we get caught up in multi-tasking. Rather than getting many things done at once and increasing productivity, we actually split our focus and make achieving each of our tasks difficult and taxing. When we try to handle email, take phone calls, and work on weekly reporting, Say a contractor can’t adhere to his scheduled appointment and at the same time, a friend wants to discuss a death in her family. You accept her call; however, you continue contemplating when you can reschedule your absent contractor since the work will take time out of your own job. While talking with your friend, your concentration is off and you give minimum responses as she explains the details of her loss while you are searching for the next opening on your calendar. Your friend senses the disconnect and eventually ends the call in a disappointed manner. You then realize that you let her down since you weren’t giving her your full attention. Sure, things happen, and at times situations are unavoidable. It is just when things happen too often and too much is happening at once due to over scheduling is when things get out of hand. ====================================== TO_OWNERS_AND_COPYRIGHT: This channel is created to promote the best informative videos releated Health Technology Science nature performers,and producers.

esearch reveals that some young people can recover from schizophrenia. Until recently, medical professionals believed that only a minority of patients could recover from schizophrenia. But now, new Norwegian research suggests that more than half of the study participants are doing well. After four years of treatment, 55 per cent of the young people were partially or fully recovered, and fully ten per cent of those who are fully recovered no longer use medication."Having such a high proportion be well-functioning shows that schizophrenic patients have a greater potential to get well than previous research has shown," says Professor Anne-Kari Torgalsbøen at the University of Oslo’s Department of Psychology. She believes too much pessimism has been associated with this diagnosis. "The results of this study give hope not only to patients and their relatives, but also provide inspiration for everyone who treats young people with psychotic disorders," #inside_human #schizophrenia #schizophrenia_treatment #schizophrenia_test #what_is_schizophrenia ====================================== TO_OWNERS_AND_COPYRIGHT: This channel is created to promote the best informative videos releated Health Technology Science nature performers,and producers.

Oxygen On Earth Originated A Billion Years Earlier Than We Thought
 
03:25
Oxygen On Earth Originated A Billion Years Earlier Than We Thought Ancient microbes may have been producing oxygen through photosynthesis a billion years earlier than we thought, which means oxygen was available for living organisms very close to the origin of life on earth. In a new article in Heliyon, a researcher from Imperial College London studied the molecular machines responsible for photosynthesis and found the process may have evolved as long as 3.6 billion years ago. The author of the study, Dr. Tanai Cardona, says the research can help to solve the controversy around when organisms started producing oxygen – something that was vital to the evolution of life on earth. It also suggests that the microorganisms we previously believed to be the first to produce oxygen – cyanobacteria – evolved later, and that simpler bacteria produced oxygen first. “My results mean that the process that sustains almost all life on earth today may have been doing so for a lot longer than we think,” said Dr. Cardona. “It may have been that the early availability of oxygen was what allowed microbes to diversify and dominate the world for billions of years. What allowed microbes to escape the cradle where life arose and conquer every corner of this world, more than 3 billion years ago.” Photosynthesis is the process that sustains complex life on earth – all of the oxygen on our planet comes from photosynthesis. There are two types of photosynthesis: oxygenic and anoxygenic. Oxygenic photosynthesis uses light energy to split water molecules, releasing oxygen, electrons and protons. Anoxygenic photosynthesis use compounds like hydrogen sulfide or minerals like iron or arsenic instead of water, and it does not produce oxygen. This image is the crystal structure of Photosystem I (PDB ID: 1JB0) Previously, scientists believed that anoxygenic evolved long before oxygenic photosynthesis, and that the earth’s atmosphere contained no oxygen until about 2.4 to 3 billion years ago. However, the new study suggests that the origin of oxygenic photosynthesis may have been as much as a billion years earlier, which means complex life would have been able to evolve earlier too. Dr. Cardona wanted to find out when oxygenic photosynthesis originated. Instead of trying to detect oxygen in ancient rocks, which is what had been done previously, he looked deep inside the molecular machines that carry out photosynthesis – these are complex enzymes called photosystems. Oxygenic and anoxygenic photosynthesis both use an enzyme called Photosystem I. The core of the enzyme looks different in the two types of photosynthesis, and by studying how long ago the genes evolved to be different, Dr. Cardona could work out when oxidative photosynthesis first occurred. He found that the differences in the genes may have occurred more than 3.4 billion years ago – long before oxygen was thought to have first been produced on earth. This is also long before cyanobacteria – microbes that were thought to be the first organisms to produce oxygen – existed. This means there must have been predecessors, such as early bacteria, that have since evolved to carry out anoxygenic photosynthesis instead. “This is the first time that anyone has tried to time the evolution of the photosystems,” said Dr. Cardona. “The result hints towards the possibility that oxygenic photosynthesis, the process that have produced all oxygen on earth, actually started at a very early stage in the evolutionary history of life – it helps solve one of the big controversies in biology today.” One surprising finding was that the evolution of the photosystem was not linear. Photosystems are known to evolve very slowly – they have done so since cyanobacteria appeared at least 2.4 billion years ago. But when Dr. Cardona used that slow rate of evolution to calculate the origin of photosynthesis, he came up with a date that was older than the earth itself. This means the photosystem must have evolved much faster at the beginning – something recent research suggests was due to the planet being hotter.

How hearing works
 
03:17
Sound funnels into the ear canal and causes the eardrum to move. The eardrum vibrates with sound. Sound vibrations move through the ossicles to the cochlea. Sound vibrations cause the fluid in the cochlea to move. Fluid movement causes the hair cells to bend. Hair cells create neural signals which are picked up by the auditory nerve. Hair cells at one end of the cochlea send low pitch sound information and hair cells at the other end send high pitch sound information. The auditory nerve sends signals to the brain where they are interpreted as sounds. ====================================== TO_OWNERS_AND_COPYRIGHT: This channel is created to promote the best informative videos releated Health Technology Science nature performers,and producers.

Glaucoma the leading cause of irreversible blindness in the world
 
03:21
Glaucoma the leading cause of irreversible blindness in the world. Glaucoma is becoming an increasingly important cause of blindness, as the world’s population ages. New statistics gathered by WHO in 2002, and published in this edition of the Bulletin (Resnikoff et al., p. 844–851), show that glaucoma is now the second leading cause of blindness globally, after cataracts. Glaucoma, however, presents perhaps an even greater public health challenge than cataracts: because the blindness it causes is irreversible. WHO officials are looking into ways to address the problems caused by glaucoma which was until now estimated to be the third leading cause of blindness. “It is a major problem, we’ve been concerned about this for some time and we are now working hard to address this important cause of blindness,” said Dr Robert Beaglehole, WHO’s Director of Chronic Diseases and Health Promotion in Geneva. “It highlights the growing problem created by chronic eye diseases, including diabetic retinopathy and age-related macular degeneration,” Beaglehole said. The urgent need for action is underscored by the philanthropic work of Swiss charity Vision For All. André Mermoud, the group’s director, is the Head of the Glaucoma Unit at the Jules Gonin Eye Hospital at the University of Lausanne in Switzerland has become known as the ‘glaucoma pope’ for his work on the disease. Mermoud told the Bulletin that governments and public health officials face “a really big task” to improve treatment for glaucoma. “Something has to be done,” Mermoud added. “Especially in Africa, it will be essential to train hundreds of eye doctors.” Glaucoma is the general term for a group of similar diseases. In primary open angle glaucoma, the channels that drain fluid within the eye become blocked, causing the pressure within the eye to rise. It causes gradual loss of vision. There are few symptoms so that people may not notice for a long time that they are losing their sight. In angle closure glaucoma, there is a similar build up of fluid within the eye, but the onset is much more sudden. Symptoms include headaches, blurred vision and pain in the eye. People of Asian descent are much more likely to suffer from angle closure glaucoma, while those of African or European origin are more likely to develop primary open angle glaucoma. In Southern India, studies have shown a prevalence of glaucoma of 2.6% and 90% of these cases have never been diagnosed before, compared to about 50% previously undiagnosed when similar studies are done in Europe. In African populations, the prevalence is 1–2%, but can rise to about 10% in the Caribbean. There are several other types of glaucoma, which are less common. The paper by Resnikoff et al. reports that about 37 million people worldwide in 2002 were blind. More than 82% of all blind people are 50 years and older. There are several reasons why glaucoma has now become the second leading cause of blindness, experts say. One is age. As a population grows older, the prevalence of glaucoma rises. ====================================== TO_OWNERS_AND_COPYRIGHT: This channel is created to promote the best informative videos releated Health Technology Science nature performers,and producers.

How Does a Plant's Immune System Work?
 
03:29
Plants have a wide range of invaders to deal with — viruses, bacteria, fungi, insects and nematodes to name a few — but they deal with these attackers very differently to the way animals and humans do, says research scientist Dr Peter Dodds from the CSIRO. "Humans and animals have a circulating immune system, where white blood cells and T-cells are circulated throughout the body in the blood, Dodds explains. "That means they can travel to the site of an infection and help protect the cells under attack. Plants don't have that circulatory system, so each cell in the plant has to be able to respond independently." Individual plant cells express receptors that recognise pathogen molecules and then trigger defence responses, which can include cell wall thickening, production of anti-microbial compounds and host cell death. "Often the best way in terms of a whole plant response is just for that cell to commit suicide," he says. "A lot of pathogens feed on living tissue, so if the immediate cells that are being infected die, it stops the pathogen from being able to access nutrients and then it can't spread through the rest of the plant." Hard-wired resistance The other main difference between plant and animal immunity is that while animals exposed to infection can adapt and acquire immunity, plants cannot. Instead, their ability to recognise and repel specific attackers is hard-wired into their genes. "If a plant with an effective resistance gene meets a new attacker and is overcome, then there's really no way of getting it to work again," says Dodds. "You've got to go and find a new genetic source of resistance. You can't make it, you have to find it; it has to exist somewhere in the wild relatives of the crop plant that you're working with." When a new strain of stem rust in wheat emerged in Africa early this century, it overcame one of the main resistance genes which had been effective for 30 to 40 years, and led to a major epidemic in Africa, which has spread throughout Africa to the Middle East. Dodds is one of many scientists who are trying to find new sources of resistance to the rust. "There 's been a lot of breeding work and prospecting work looking at the wild relatives of wheat to try to find some new resistance genes effective against that particular strain." ====================================== TO_OWNERS_AND_COPYRIGHT: This channel is created to promote the best informative videos releated Health Technology Science nature performers,and producers.

Researchers Have Discovered Ancient Tools And Bones In China
 
03:28
Researchers Have Discovered Ancient Tools And Bones In China Simple stone artefacts discovered in China have prompted a re-think of early human migration. Ancient stone tools and animal bones dating back over 2 million years suggest our ancient cousins made the colossal journey into Asia hundreds of thousands of years earlier than scientists previously thought. The remains are the latest to chart the early movements of hominins – the group of ancient humans that includes our own species – as they struck out from their homelands in AfricaEvidence for these early movements is thin on the ground as these first settler populations would have been small in number, but the primitive tools these creatures fashioned act as an effective “calling card” when actual bones are scarce. Now, a team led by Dr Zhaoyu Zhu at the Chinese Academy of Sciences has discovered nearly 100 stone artefacts in the country of Shangchen, which show these primitive humans living there between 1.3 and 2.1 million years ago. Previously, the earliest evidence for hominins outside Africa came from Georgia, where tools and bones belonging to Homo erectus have been unearthed dating back to around 1.85 million years.In China and even further east in Java hominin fossils up to 1.7 million years old have been discovered, but some have claimed human activity in the region has even more ancient roots. Now, the collection of tools – potentially used to process the animal remains found nearby – provide firm evidence for these claims. ====================================== TO_OWNERS_AND_COPYRIGHT: This channel is created to promote the best informative videos releated Health Technology Science nature performers,and producers.

Bacteria Genetically Engineered To Treat Constipation
 
03:14
Bacteria Genetically Engineered To Treat Constipation Genetically engineered bacteria are showing promise as a new treatment for constipation, researchers at the Mayo Clinic Center for Individualized Medicine have discovered in a mouse study. The finding is significant in part because there are few approved constipation remedies on the market. The research is published in Cell Host & Microbe. Because the community of bacteria found within the stomach and intestines — known as the gut microbiome — is unique to each person, generic probiotics don’t work for everyone. Probiotics are live bacteria that can aid in digestion. The genetically engineered bacteria in the Mayo study produced large amounts of the chemical tryptamine. This chemical helps food pass through the intestines with potentially less risk of side effects than other constipation drugs. “Tryptamine is similar to the chemical serotonin, which is produced in our gut," says lead author Purna. Kashyap, M.B.B.S., associate director of the Center for Individualized Medicine Microbiome Program. "In this study, we found tryptamine can activate a receptor in the mouse gut that normally responds to serotonin, causing increased secretion of fluid from the lining of the colon. Bacteria can direct the colon to secrete water via tryptamine acting on a host receptor in mice. This accelerates the movement of food through the digestive system." For decades, people with constipation have often been advised to change their diets, but that hasn’t worked universally because everyone is unique in terms of their genes and microbiome, Dr. Kashyap says. “These synthetic bacteria spur transit of food through the digestive system without messing with diet and microbes,” he says. Bacterially produced tryptamine quickly degrades in the intestine and does not appear to increase in the bloodstream. That reduces the risk of side effects outside the gastrointestinal tract. Other drugs for constipation can affect different areas of the body, including the heart. “Our goal with this research is to find treatments that act only in the GI tract without creating problems in other parts of the body,” Dr. Kashyap says. The findings are also important to the study of gastrointestinal disorders such as irritable bowel syndrome. Additional preclinical studies will be done to verify the findings: A clinical trial with humans is likely at least three years away, Dr. Kashyap says. subscribe this channel https://www.youtube.com/channel/UC4GrKzQc0n-i8DsjH_ynkNA?view_as=subscriber Google plus https://plus.google.com/102332871130341184209 twitter https://twitter.com/InsideHuman2 instagram https://www.instagram.com/insidehuman2018/?hl=en

E Cigarette Vapor Contains Toxic Heavy Metals
 
03:23
E Cigarette Vapor Contains Toxic Heavy Metals In the latest to and fro on the science of e-cigarette safety, there’s fresh evidence to suggest that potentially unsafe levels of toxic metals could be making their way into e-cig vapors. Scientists at John Hopkins University have found there’s lead, arsenic, chromium, manganese, and nickel in the vapor of modifiable vaping devices. As you can imagine, these are not good for you. Long-term exposure and persistent inhalation of the metals have been linked to lung, liver, immune, cardiovascular, and brain damage, and even cancers. "It's important for the FDA, the e-cigarette companies, and vapers themselves to know that these heating coils, as currently made, seem to be leaking toxic metals – which then get into the aerosols that vapers inhale," senior author Ana María Rule, PhD, said in a statement. In the study, published in Environmental Health Perspectives, researchers gathered 56 modifiable vaping devices from vape shops and vaping conventions around Baltimore. They then tested for the presence of 15 metals in the e-liquids in their coil-containing e-cigarette tanks, the refilling dispenser, and the vapor. While they only found small amounts of toxic metal in the e-liquids alone, they discovered considerable amounts in the e-liquids that had been exposed to the heating coils. This indicates, the researchers say, that the metals almost “leak” from the metallic heating coils. They went on to show that the metals can then end up in the aerosols, i.e. the vapor, from the heated e-liquid. "We don't know yet whether metals are chemically leaching from the coil or vaporizing when it's heated," Rule said. The researchers added that concentrations of the nasty metals appeared to be higher in e-cigarettes with more frequently changed heated coils, suggesting that fresher coils might be the problem. Although inhaling these metals has been associated with health risks in previous studies, the researchers now hope to see whether this particular form of exposure can also have an effect on a person's health. "We've established with this study that there are exposures to these metals, which is the first step, but we need also to determine the actual health effects,” said Rule. The safety of vaping is a hot topic of debate, with a bundle of new studies on their safety coming out every single month, each seemingly saying something totally different from the last. Much more science needs to be done until the risks are crystal clear, but the current consensus is that e-cigarettes are most likely bad for your health, although they are considerably less bad for your health than smoking tobacco. ====================================== TO_OWNERS_AND_COPYRIGHT: This channel is created to promote the best informative videos releated Health Technology Science nature performers,and producers.

Rising sea levels will cost the world $14 trillion annually by 2100
 
03:22
Rising sea levels will cost the world $14 trillion annually by 2100 Rising sea levels could cost $14 trillion worldwide annually by 2100, say scientists who warn that failing to limit global warming to two degrees Celsius will lead to dire global economic consequences. The researchers from UK National Oceanographic Centre (NOC) also found that upper-middle income countries such as China would see the largest increase in flood costs, whereas the highest income countries would suffer the least, thanks to existing high levels of protection infrastructure. "More than 600 million people live in low-elevation coastal areas, less than 10 metres above sea level. In a warming climate, global sea level will rise due to melting of land-based glaciers and ice sheets, and from the thermal expansion of ocean waters," said Svetlana Jevrejeva, from the NOC. "So, sea level rise is one of the most damaging aspects of our warming climate," said Jevrejeva, lead author of the study published in the journal Environmental Research Letters. Sea level projections exist for emissions scenarios and socio-economic scenarios. However, there are no scenarios covering limiting warming below the two degrees Celsius and 1.5 degree Celsius targets during the entire 21st century and beyond.The study team explored the pace and consequences of global and regional sea level rise with restricted warming of 1.5 and 2 degrees Celsius, and compared them to sea level projections with unmitigated warming Using World Bank income groups (high, upper middle, lower middle and low income countries), they then assessed the impact of sea level rise in coastal areas from a global perspective, and for some individual countries using the Dynamic Interactive Vulnerability Assessment modelling framework. "We found that with a temperature rise trajectory of 1.5 degree Celsius, by 2100 the median sea level will have risen by 0.52 metres. But, if the 2 degree Celsius target is missed, we will see a median sea level rise of 0.86 metres, and a worst-case rise of 1.8 metres," Jevrejeva said. "If warming is not mitigated and follows the RCP 8.5 sea level rise projections, the global annual flood costs without adaptation will increase to $14 trillion per year for a median sea level rise of 0.86 metres, and up to $27 trillion per year for 1.8 metres. This would account for 2.8 per cent of global GDP in 2100," she said. The projected difference in coastal sea levels is also likely to mean tropical areas will see extreme sea levels more often. "These extreme sea levels will have a negative effect on the economies of developing coastal nations, and the habitability of low-lying coastlines. ====================================== TO_OWNERS_AND_COPYRIGHT: This channel is created to promote the best informative videos releated Health Technology Science nature performers,and producers.

Immune Cells Mistake Heart Attacks For Viral Infections
 
03:25
Immune Cells Mistake Heart Attacks For Viral Infections A study led by Kevin King, a bioengineer and physician at the University of California San Diego, has found that the immune system plays a surprising role in the aftermath of heart attacks. The research could lead to new therapeutic strategies for heart disease. The team, which also includes researchers from the Center for Systems Biology at Massachusetts General Hospital (MGH), Brigham and Women’s Hospital, Harvard Medical School, and the University of Massachusetts, presents the findings in the Nov. 6 issue of Nature Medicine. Ischemic heart disease is the most common cause of death in the world and it begins with a heart attack. During this process, heart cells die, prompting immune cells to enter the dead tissue, clear debris and orchestrate stabilization of the heart wall. But what is it about dying cells in the heart that stimulates the immune system? To answer this, researchers looked deep inside thousands of individual cardiac immune cells and mapped their individual transcriptomes using a method called single cell RNA-Seq. This led to the discovery that after a heart attack, DNA from dying cells masquerades as a virus and activates an ancient antiviral program called the type I interferon response in specialized immune cells. The researchers named these “interferon inducible cells (IFNICs).” When investigators blocked the interferon response, either genetically or with a neutralizing antibody given after the heart attack, there was less inflammation, less heart dysfunction, and improved survival. Specifically, blocking antiviral responses in mice improved survival from 60 percent to over 95 percent. These findings reveal a new potential therapeutic opportunity to prevent heart attacks from progressing to heart failure in patients. “We are interested to learn whether interferons contribute to adverse cardiovascular outcomes after heart attacks in humans,” said King, who did most of the work on the study while he was a cardiology fellow at Brigham and Women’s Hospital and at the Center for Systems Biology at MGH in Boston. The immune system has evolved innate antiviral programs to defend against a diverse range of invading pathogens. Immune cells do this by detecting molecular fingerprints of pathogens, activating a protein called IRF3, and secreting interferons, which orchestrate a defense program mediated by hundreds of interferon-stimulated genes. Investigators found that surprisingly, the antiviral interferon response is also turned on after a heart attack despite the absence of any infection. Their results point to dying cell DNA as the cause of this confusion because the immune system interprets it as the molecular signature of a virus. Surprisingly, the immune cells participating in the interferon response were a previously unrecognized subset of cardiac macrophages. These cells could not be identified by conventional flow sorting because unique markers on the cell surface were not known. By using single cell RNA Seq, an emerging technique that combines microfluidic nanoliter droplet reactors with single cell barcoding and next generation sequencing, the researchers were able to examine expression of every gene in over 4,000 cardiac immune cells and found the specialized IFNIC population of responsible cells. Future studies will aim to better understand the interferon response and the IFNIC cell type and explore their roles in the infarcted and remodeling heart. The team is also working to understand the interferon response in other tissues and diseases where cell death occurs. ====================================== TO_OWNERS_AND_COPYRIGHT: This channel is created to promote the best informative videos releated Health Technology Science nature performers,and producers.

Crows' reasoning ability rivals that of seven year old humans
 
05:00
Crows' reasoning ability rivals that of seven year old humans New Caledonian crows are as good at reasoning as a human seven-year-old, claim researchers. The scientists subjected six wild crows to a battery of tests designed to challenge their understanding of causal relationships. The "water displacement" tasks were all variations of an Aesop's fable in which a thirsty crow drops stones to raise the level of water in a pitcher. In the study, crows worked out how to obtain floating food rewards by dropping heavy objects into water-filled tubes. They demonstrated an ability to choose objects that would sink rather than float, and solid rather than hollow objects, and they were able to choose a high water level tube over one with a low water level, and a water-filled tube over one filled with sand. The crows failed on two more difficult tasks. One required an understanding of the width of the tube and the other involved displacing water in a U-shaped tube. Nevertheless, the birds' understanding of the effects of volume displacement matched that of human children aged five to seven, said the scientists. Lead researcher Sarah Jelbert from the University of Auckland, New Zealand, said: "These results are striking as they highlight both the strengths and limits of the crows' understanding. "In particular, the crows all failed a task which violated normal causal rules, but they could pass the other tasks, which suggests they were using some level of causal understanding when they were successful." New Caledonian crows, named after the Pacific islands where they live, are famous for their intelligence and inventiveness. They are the only non-primate species known to fashion tools, such as sticks and hooks which they use to winkle out grubs from logs and branches. ====================================== TO_OWNERS_AND_COPYRIGHT: This channel is created to promote the best informative videos releated Health Technology Science nature performers,and producers.

Brain implant boosts human memory by up to 30%
 
03:47
Brain implant boosts human memory by up to 30% A “memory prosthesis” brain implant has enhanced human memory for the first time. The device is comprised of electrodes implanted in the brain, and is designed to mimic the way we naturally process memories, and can boost performance on memory tests by up to 30 per cent. A similar approach may work for enhancing other brain skills, such as vision or movement, says the team behind the work. “We are writing the neural code to enhance memory function,” says Dong Song of the University of Southern California, who presented the findings at the Society for Neuroscience meeting in Washington DC over the weekend. “This has never been done before.” The team’s implant gives small electric shocks to the hippocampus, a brain region vital for learning and memory. By releasing bursts of electricity in a pattern that mimics normal, healthy brain activity patterns, it is hoped that the device will help with disorders involving memory problems, such as dementia, and even be adapted for other brain areas, to boost other types of brain function. Song and his colleagues implanted their device in 20 volunteers who were having electrodes put into their brains anyway, to treat epilepsy. First, the team used the device to collect data on patterns of activity in the brain when the people were learning. Each volunteer performed a memory test, in which they had to remember which unusual, blobby shapes they had been shown 5 to 10 seconds before. This test measures short-term memory, and people normally score around 80 per cent on this task. They also did a more difficult version of the test, in which they had to remember images they had seen between 10 and 40 minutes ago. This measures working memory – the things we keep at the front of our minds while making decisions, for example. ====================================== TO_OWNERS_AND_COPYRIGHT: This channel is created to promote the best informative videos releated Health Technology Science nature performers,and producers.

Nearly One Million People Commit Suicide Each Year
 
03:19
Nearly One Million People Commit Suicide Each Year Suicide Suicide is the tenth leading cause of death globally. In the USA there are two suicides for every homicide. Worldwide, the suicide rate has gone up by 60% over the last five decades - mainly in industrialized nations. 60% of all suicides occur in Asia. China India and Japan account for about 40% of all suicides, according to WHO. 16.5% of suicides in the USA are alcohol-related. An alcoholic has between 5 and 20 times the risk of committing suicide compared to the rest of the population. Individuals who misuse drugs are 10 to 20 times more likely to take their own lives. Approximately 33% of suicides among those younger than 35 years of age have a primary diagnosis of alcohol or other substance misuse. Among adolescent suicides, alcohol or drug misuse are factors in up to 70% of cases. In Western countries, men commit suicide more often than women, but women attempt suicide more frequently. Experts say this is probably because men are more willing to end their lives through effective violent means. In the majority of countries throughout the world, drug overdoses make up approximately two-thirds of suicides among females and one-third among males. credit goes to https://www.youtube.com/user/hashemalghaili subscribe this channel https://www.youtube.com/channel/UC4GrKzQc0n-i8DsjH_ynkNA?view_as=subscriber Google plus https://plus.google.com/102332871130341184209 twitter https://twitter.com/InsideHuman2

Bee swarms work like giant brains
 
03:59
Bee swarms work like giant brains . On their own, bee brains are fairly remarkable things, although human computing power still trumps them. But new research suggests that individual members of a swarm behave surprisingly like neurons in a human brain.Not only does this tell us something about how these remarkable creatures interact - studying 'bee speak' could tell us a thing or two about how our own minds make decisions. A team of researchers from the University of Sheffield in the UK applied a theoretical model commonly used to study human psychology to the behaviour of bee colonies. It's not unusual for scientists to see if animals follow the kinds of psychological laws that govern our own brains. For example, in the field of psychophysics a rule called Weber's law describes a relationship between the size of a stimulus and noticeable increases in its magnitude. It works like this: imagine lifting an apple, compared to lifting three apples - you'd notice a difference. But if somebody secretly slipped a few apples into your overloaded shopping bag, it's unlikely you'd spot the difference. This general rule about stimulus and perception has been observed in all manner of animals, from other mammals to birds to fish. While the law also seems to fit the collective behaviour of simpler organisms – it's been observed in brainless amoeba such as slime mould – it hadn't yet been studied in whole clusters of tiny brains such as an insect hive.

Pregnancy and Breastfeeding Reduce the Risk of Breast Cancer
 
03:54
Pregnancy and Breastfeeding Reduce the Risk of Breast Cancer A review of the latest scientific research on breast cancer shows that there is strong evidence that breast-feeding can reduce women's risk of premenopausal and postmenopausal breast cancers.A report on the review, by the American Institute for Cancer Research (AICR) and the World Cancer Research Fund (WCRF), has been released this week to mark World Breastfeeding Week. The report offers several possible explanations for how breast-feeding lowers breast cancer risk. One reason is that lactation delays when women start menstruating again after giving birth. This reduces lifetime exposure to hormones such as estrogen, which are linked to increased risk of breast cancer.The report also suggests that lactation may change the expression of genes in breast cells in a way that exerts a "lasting impact" on the risk of cancer development. ====================================== TO_OWNERS_AND_COPYRIGHT: This channel is created to promote the best informative videos releated Health Technology Science nature performers,and producers.

A single blood test can detect 8 types of cancer
 
03:45
A single blood test can detect 8 types of cancer Researchers have developed a new blood test that can detect eight common types of cancer, including the notoriously elusive liver and pancreatic cancers. Some day, doctors may be able to use this method to spot cancers in their early stages — before the onset of symptoms — thus improving patients' chances of successful treatment and survival. The test, called CancerSEEK, looks for a number of compounds in the blood that are thought to be early signs of cancer. These include 16 different cancer "driver genes" — genes that are associated with tumors — and eight proteins, according to the study describing the test, which was published Jan. 18 in the journal Science. "The sort of ultimate vision is that at the same time that you are getting your cholesterol checked when you are getting your annual physical, you will also get your blood screened for cancer," said lear] What's more, the test appears to be able to screen for five cancers for which screening tests aren't currently available: ovarian, stomach, esophageal, liver and pancreatic. These cancers typically don't cause symptoms until they reach more advanced stages of the disease, when treatment becomes difficult. Liquid biopsies so-called "liquid biopsy" tests — tests that look for markers of cancer in the blood — is the use of two types indicators (genes and p The test uses an artificial-intelligence algorithm to analyze the combinations of genes and protein biomarkers found in the blood sample and identify which type of cancer the patient likely has, Cohen said. The tool could be particularly important for general practitioners, who could administer the test and then send their patient for additional testing to verify the result, he said. For example, if the blood-test results suggest stomach cancer, a doctor could recommend the patient get an endoscopy to confirm the results, Cohen said. Similarly, test results pointing to colon cancer could lead to a colonoscopy. To study how well the blood test worked, the researchers tried it on about 1,000 patients with known diagnoses of cancer that hadn't metastasized, or spread to other parts of the body. These cancers included breast, ovarian, stomach, liver, pancreatic, esophageal, colorectal and lung. The researchers also enrolled about 800 healthy patients without cancer to serve as a control group. The test detected cancer with 69 to 98 percent accuracy, the study found. And the more advanced the cancer, the higher the accuracy. But for cancers in an early stage — for example, stage one cancers — the test accurately detected cancer just 40 percent of the time. Independent experts see this relatively low figure as the major weakness of the test. [7 Cancers You Can Ward Off with Exercise] Low sensitivity? "The sensitivity of the test in stage one cancer is quite low, about 40 percent," said Dr. Mangesh Thorat, deputy director of the Barts Clinical Trials Unit at the Center for Cancer Prevention at Queen Mary University of London. Thorat was not involved in the new study. "Even with stage one and two combined, it appears to be around 60 percent," Thorat told Live Science. "So the test will still miss a large proportion of cancers at the stage where we want to diagnose them." The blood test also detected cancer in 1 percent of the control group, according to the study. This could either mean that the test has a 1 percent false-positive rate (in other words, it falsely points to cancer 1 percent of the time) or that the individuals do in fact have cancer that has not yet been diagnosed, Cohen said. "The test needs to be validated in a large-scale study that would evaluate tens of thousands of healthy individuals to confirm the sensitivity and specificity," Cohen said. "It's really important to confirm the results and demonstrate that this test would work in a real-world" setting. Cohen said the researchers want to increase the sensitivity and accuracy of the test by including additional types of biomarkers. #blood_test_for_cancer #inside_human_channel #cancer_symptoms#cancer_stages #blood_test_to_detect_cancer #types_of_cancer#cancer_facts #hashem_al_ghalilli_videos ====================================== TO_OWNERS_AND_COPYRIGHT: This channel is created to promote the best informative videos releated Health Technology Science nature performers,and producers.

The science of dreaming  [intresting fact of dreaming]
 
03:57
The science of dreaming [intresting fact of dreaming] For centuries people have pondered the meaning of dreams. Early civilizations thought of dreams as a medium between our earthly world and that of the gods. In fact, the Greeks and Romans were convinced that dreams had certain prophetic powers. While there has always been a great interest in the interpretation of human dreams, it wasn’t until the end of the nineteenth century that Sigmund Freud and Carl Jung put forth some of the most widely-known modern theories of dreaming. Freud’s theory centred around the notion of repressed longing -- the idea that dreaming allows us to sort through unresolved, repressed wishes. Carl Jung (who studied under Freud) also believed that dreams had psychological importance, but proposed different theories about their meaning. Since then, technological advancements have allowed for the development of other theories. One prominent neurobiological theory of dreaming is the “activation-synthesis hypothesis,” which states that dreams don’t actually mean anything: they are merely electrical brain impulses that pull random thoughts and imagery from our memories. Humans, the theory goes, construct dream stories after they wake up, in a natural attempt to make sense of it all. Yet, given the vast documentation of realistic aspects to human dreaming as well as indirect experimental evidence that other mammals such as cats also dream, evolutionary psychologists have theorized that dreaming really does serve a purpose. In particular, the “threat simulation theory” suggests that dreaming should be seen as an ancient biological defence mechanism that provided an evolutionary advantage because of its capacity to repeatedly simulate potential threatening events – enhancing the neuro-cognitive mechanisms required for efficient threat perception and avoidance. So, over the years, numerous theories have been put forth in an attempt to illuminate the mystery behind human dreams, but, until recently, strong tangible evidence has remained largely elusive. #science_of_dreaming #inside_human_channel #rem_sleep_cycle ====================================== TO_OWNERS_AND_COPYRIGHT: This channel is created to promote the best informative videos releated Health Technology Science nature performers,and producers.

Lack of exercise can shrink your brain

Lack of exercise can shrink your brain The research suggests that people with poor levels of physical fitness in their thirties and forties may be linked to a smaller brain size 20 years later.Study author Doctor Nicole Spartano, of Boston University School of Medicine in the United States, said: "We found a direct correlation in our study between poor fitness and brain volume decades later, which indicates accelerated brain ageing." For the study, 1,583 people enrolled in the Framingham Heart Study, with an average age of 40 and without dementia or heart disease, took a treadmill test.They took another one two decades later, along with MRI brain scans. The researchers also analysed the results when they excluded participants who developed heart disease or started taking beta blockers to control blood pressure or heart problems; this group had 1,094 people. The participants had an average estimated exercise capacity of 39 mL/kg/min, which is also known as peak VO2, or the maximum amount of oxygen the body is capable of using in one minute.Exercise capacity was estimated using the length of time participants were able to exercise on the treadmill before their heart rate reached a certain level. For every eight units lower a person performed on the treadmill test, their brain volume two decades later was smaller, equivalent to two years of accelerated brain ageing. #shrinkage_of_brain #inside_human_channel #brain_tumor #exersise_of_brain ====================================== TO_OWNERS_AND_COPYRIGHT: This channel is created to promote the best informative videos releated Health Technology Science nature performers,and producers.

Childhood Memories Before The Age Of 3 Are Fictional
 
03:26
Childhood Memories Before The Age Of 3 Are Fictional In the largest survey on the subject of first memories, researchers have concluded it is improbable that humans remember anything before three-and-a-half years of age. The study, published in the Psychological Science Journal, found 40 per cent of people’s first memories are fictional - as they claim to remember events that occurred at the age of two or earlier.To study childhood memory, the researchers asked 6,641 people to recall their very first memory and confirm that it “wasn’t related to a family story or photograph,” according to Conway - as false memories are often the result of seeing photographs or hearing stories of one’s childhood. #Childhood_Memories #inside_human ====================================== TO_OWNERS_AND_COPYRIGHT: This channel is created to promote the best informative videos releated Health Technology Science nature performers,and producers.

A painkiller more powerful than morphine is extracted from snail venom
 
03:58
painkiller more powerful than morphine is extracted from snail venom Five compounds have been created that appear to control chronic pain in rats to an unprecedented degree, all based on a protein found in cone snail venom. The announcement was made by Dr David Craik to the American Chemical Society at its conference in Dallas. Pain is an extremely complex process, with multiple channels for transmitting pain signals. While painkillers are effective at blocking specific channels, we know very little about how to control certain sorts of pain. In particular, we are generally much better at treating acute pain caused by a sudden injury than chronic neuropathic pain from sources such as diabetes, cancer or MS. Craik noted that treatments that do exist for these sorts of pain generally only make a major difference to one in three patients and come with serious side effects. Many of the most promising chemicals for chronic pain relief come from venomous animals. Evolution has honed the proteins in venoms to a remarkable degree, and with venoms changing much faster than the animals themselves when species become separated there are a lot of options to study. Exactly why so many of these venoms have analgesic effect is not clear – it is not as if the biters and stingers have decided to take pity on their victims by giving them an easy death. Nevertheless, the potential is enormous. Cone snails are gastropod mollusks common on coral reefs and in tropical tidal zones. Their venom is held in a gland within a tooth which they fire at prey or enemies like a harpoon. The smaller species produce a painful sting like a bee, but larger ones can be fatal. In their raw form conotoxins are broken down by the body's enzymes and therefore cannot be taken orally. Ziconotide is the first painkiller based on cone snail toxins, but Craik says it needs to be injected directly into the lower spinal cord, greatly limiting its application. However, by modifying some of the cone snail's proteins to form a loop of amino acids Craik has made them far more stable. Although they have yet to be tried on humans, these modified peptides (small proteins) appear to dramatically reduce pain response in rats, even when given in very small doses. Craik estimates the effect is 100 times as large as morphine or gabaentin, the benchmark pain relief drugs. Since the cone-based drugs target different receptors to opiates it is thought unlikely they would produce the same addiction response. “We don’t know about side effects yet, as it hasn’t been tested in humans. But we think it would be safe,”, Craik said. A few days after the talk Craik's colleagues at the University of Queensland revealed in Nature Communications that cone snails use different venoms for hunting prey and defending themselves against predators. “Most venomous animals are thought to inject the same combination of venom toxins for both hunting prey and defending themselves from predators,” said Professor Richard Lewis. “We found that the geography cone [Conus geographus] only injects this lethal venom when it feels threatened and acts in defense,” Lewis said. “However, when hunting prey such as fish, they inject a less powerful and complex venom that isn’t toxic to humans, effectively switching weapons to match the situation.” Craik identified the way small cone snail venom proteins inhibit pain sensors in the Journal of Neuroscience in 2008. He predicted at the time that these proteins might eventually be used to control chronic pain, but the path to drug development in an area like this is usually slow and winding. Nor is that path near completion. Craik thinks human trials are two years away, making widespread use a long term prospect. subscribe this channel https://www.youtube.com/channel/UC4GrKzQc0n-i8DsjH_ynkNA?view_as=subscriber Google plus https://plus.google.com/102332871130341184209 twitter https://twitter.com/InsideHuman2 credit goes to https://www.facebook.com/ScienceNaturePage/?hc_ref=ARRaF5UJfpWqD2Pd_pBTZw2G3a1vv4jpQvQpAxygzMn0nV7NUFCordW9Q3oFpqNrN88 youtube channel https://www.youtube.com/user/hashemalghaili

Attention deficit hyperactivity disorder ADHD
 
03:38
Attention deficit hyperactivity disorder ADHD Do you find it hard to pay attention? Do you feel the need to move constantly during times when you shouldn’t? Do you find yourself constantly interrupting others? If these issues are ongoing and you feel that they are negatively impacting your daily life, it could be a sign of attention-deficit/hyperactivity disorder (ADHD). ADHD is a disorder that makes it difficult for a person to pay attention and control impulsive behaviors. He or she may also be restless and almost constantly active. ADHD is not just a childhood disorder. Although the symptoms of ADHD begin in childhood, ADHD can continue through adolescence and adulthood. Even though hyperactivity tends to improve as a child becomes a teen, problems with inattention, disorganization, and poor impulse control often continue through the teen years and into adulthood. What causes ADHD? Researchers at the National Institute of Mental Health (NIMH), National Institutes of Health (NIH), and across the country are studying the causes of ADHD. Current research suggests ADHD may be caused by interactions between genes and environmental or non-genetic factors. Like many other illnesses, a number of factors may contribute to ADHD such as: Genes Cigarette smoking, alcohol use, or drug use during pregnancy Exposure to environmental toxins, such as high levels of lead, at a young age Low birth weight Brain injuries. ====================================== TO_OWNERS_AND_COPYRIGHT: This channel is created to promote the best informative videos releated Health Technology Science nature performers,and producers.

Amazing Facts About Hurricanes
 
03:19
Amazing Facts About #Hurricanes A tropical storm is classified as a hurricane once winds goes up to 74 miles per hour or higher. Hurricanes are the only weather disasters that have been given their own names. All hurricanes begin life in a warm moist atmosphere over tropical ocean waters. A single hurricane stirs up millions of miles of air and can dump more than 2.4 trillion gallons (9 trillion liters) of rain a day.[6] Hurricane-generated waves frequently toss tons of fish onto beaches. The eyes of many of the fish have popped out because of sudden changes in pressure.[1] Hurricanes produce enough energy in one day to run the lights of Las Vegas for many years.[1] Christopher Columbus wrote the first known report of a hurricane in 1495.[4] The word “hurricane” comes from Huracan, a name for the god of evil on some islands in the Caribbean.[7] In 1900, a hurricane in Galveston, Texas, killed more than 8,000 people, making it the deadliest weather emergency in U.S. history.[1] Crazy Hurricane Facts The direction of a hurricane's spin depends on the hemisphere in which is it brewing Hurricanes in the Southern Hemisphere spin in a clockwise direction. Hurricanes in the Northern Hemisphere turn counterclockwise.[9] The right side of a hurricane in the Northern Hemisphere is often stronger in terms of winds, tornadoes, and storm surge.[2] Five of the 10 most costly hurricanes in the U.S. have occurred since 1990.[4] Hurricanes have killed approximately 1.9 million people worldwide over the past 200 years.[4] The deadliest hurricane on record is the 1970 Bhola Cyclone in Bangladesh, which killed between 150,000-300,000 people.[3][5] Most of the deadliest hurricanes have occurred in southeastern Asia and India due to flooding on low-lying, densely populated areas.[3] A hurricane makes “landfall” when its center, not its edge, crosses the coastline.[4] With 210 mile-per-hour winds at landfall, Hurricane Camille (1969) is the strongest hurricane to strike land. Typhoon Tip (1979), which did not strike land, is considered to be the largest, with tropical storm-force winds 1,350 miles in diameter.[4] A hurricane can reach 40,000 to 50,000 feet up into the sky.[2] Hurricane Andrew (1992) ripped an 80-foot steel beam weighing several tons off a building and flung it more than a block away.[7] The largest hurricane can be the size of the state of Montana, 600 miles (966 kilometers) wide.[1] Ninety percent of all hurricane deaths result from storm surges, which can reach over 20 feet high and extend nearly 100 miles Hurricanes never form at the equator because they need the Coriolis Force, which is very weak at the equator, to spin.[4] Although hurricanes can cause terrible damage, they are an important part of Earth’s complicated weather system. Like giant fans, they take hot air from the tropics and move it toward the poles. They help balance temperatures and moisture around the Earth. Without hurricanes and other storms, vast areas of the planet would be too hot for animal and human life.[4] In A.D. 1281, a hurricane killed 100,000 Mongols who were attacking Japan. The Japanese thanked their storm gods for the kamikaze, which means divine wind from the gods.[1] There are several differences between hurricanes and tornadoes. First, hurricanes last several days; tornadoes last only minutes (or, rarely, hours). Hurricanes are on average about 2,000 times bigger across than tornadoes. As an analogy, if a tornado were as wide as a hamburger, a hurricane would be the length of an entire football stadium.[4] During the Galveston hurricane of 1900, nuns used ropes to tie themselves to rows of children in orphanages, but the floodwater was too hard and fast. People found the nuns still tied to the children after the flood. They had all drowned.[1] Hurricanes often spawn tornadoes. For example, Hurricane Andrew (1992) spawned 62 tornadoes, and Hurricane Beulah (1967) created a whopping 141 tornadoes. Tornadoes can occur days after a hurricane’s landfall.[4] Hurricanes never combine to form one stronger storm. However, the storms may circle each other, which is known as the Fujiwhara effect. subscribe this channel https://www.youtube.com/channel/UC4GrKzQc0n-i8DsjH_ynkNA?view_as=subscriber Google plus https://plus.google.com/102332871130341184209 twitter https://twitter.com/InsideHuman2 instagram https://www.instagram.com/insidehuman2018/?hl=en

Human Activity is Causing Cancer in Wild Animals
 
03:20
Human Activity is Causing Cancer in Wild Animals Do you know that humans are not the only ones developing cancer? Even wild animals suffer from the disease. But the primary reasons for this are human activities, says a study. Mathieu Giraudeau and Tuul Sepp, two post doctoral researchers at the School of Life Sciences in Arizona State University, and Kevin McGraw, professor at ASU believe that humans are altering environment in a manner that causes cancer in the wild animal population. They say that since human activities are likely to increase cancer rate in wild animals, there is an urgent need for more research into this topic. “We are changing the environment to be more suitable for ourselves and these changes are impacting many species negatively on many different levels, including the probability of developing cancer,” said Sepp. Giraudeau and Sepp were supported by a team of international researchers. They examined many previous scientific studies that showed how human activities were affecting animals. Such instances include chemical and physical pollution in oceans and waterways, accidental release of radiation into the atmosphere from nuclear plants and the accumulation of micro plastics in both land and water based environments. Apart from these, exposure to pesticides and herbicides on farmlands, artificial light pollution, loss of genetic diversity and animals eating human food are also known to have caused health issues in animals. “We recently published several theoretical papers on this topic, but this time, we wanted to highlight the fact that our species can strongly influence the prevalence of cancer in many other species of our planet,” said Giraudeau. The study calls humans an oncogenic species for altering the environment in a manner that is causing cancer in other wild species. While giving examples, Tuul Sepp said wild species are now more in contact with humans than ever before and this increases their closeness to anthropogenic food sources. Another example the researcher gave was that those wild animals living close to cities and roads can develop cancer as light at night can cause hormonal changes and may lead to cancer. He also gives example of birds, their hormones that are linked to cancer in humans are affected by light at night. Therefore, the next step should be to study if it also affects their probability of developing tumours. Meanwhile, the researchers highlight that it is not an easy subject to study mainly due to the difficulty of detecting and measuring oncogenic processes in wild populations. The study gives the example of alteration of the microbiome community of wild animals due to anthropogenic effects. For instance, birds due to urbanisation, pesticides exposure in honeybees, climate change in lizards and habitat fragmentation in African primate. Although there are multiple factors that are linked to these changes, change in diet is one of the main causes. These researchers are trying to develop some biomarks to study this issue. They would be measuring cancer prevalence in human-impacted environments and at the same time in more preserved areas for the same species. If it is proved that human are in fact the primary cause of cancer in wild animals, then there is a huge probability that many species are at more risk than we know. “To me, the saddest thing is that we already know what to do. We should not destroy the habitats of wild animals, pollute the environment, and feed wild animals human food. The fact that everybody already knows what to do, but we are not doing it, makes it seem even more hopeless,” said Sepp. The researcher concludes by saying that there might still be hope in education. So there is a hope that future policy makers or decision makers will be more considerate and aware about the anthropogenic effects on the environment. #Human_Activity_copusing_cancer #cancer_in_animal#inside_human_channel #hashem_al;_ghalilli_videos ====================================== TO_OWNERS_AND_COPYRIGHT: This channel is created to promote the best informative videos releated Health Technology Science nature performers,and producers.

The Most Venomous Snakes in The World Poisonous snakes are fascinating and scary at the same time. A snake is classified as poisonous when they’re capable of injecting venom. A snake is poisonous by definition as it harms you via touch or when you eat it. These top ten most poisonous snakes are feared in the countries they live because of their toxic venom that can kill a human rapidly. In this article, we’ll be talking about the lethal dose (LG) measurement. This measurement is the milligrams of toxin per kilo of body mass. For example, a certain type of snake with LD50 will kill 50% of it’s prey on average. ====================================== TO_OWNERS_AND_COPYRIGHT: This channel is created to promote the best informative videos releated Health Technology Science nature performers,and producers.

how vaccine are important for your health
 
03:52
how vaccine are important for your health an antigenic substance prepared from the causative agent of a disease or a synthetic substitute, used to provide immunity against one or several diseases. "there is no vaccine against HIV infection" Parents want to do everything possible to make sure their children are healthy and protected from preventable diseases. Vaccination is the best way to do that. Vaccination protects children from serious illness and complications of vaccine-preventable diseases which can include amputation of an arm or leg, paralysis of limbs, hearing loss, convulsions, brain damage, and death. • Vaccine-preventable diseases, such as measles, mumps, and whooping cough, are still a threat. They continue to infect U.S. children, resulting in hospitalizations and deaths every year. Though vaccination has led to a dramatic decline in the number of U.S. cases of several infectious diseases, some of these diseases are quite common in other countries and are brought to the U.S. by international travelers. If children are not vaccinated, they could easily get one of these diseases from a traveler or while traveling themselves. Outbreaks of preventable diseases occur when many parents decide not to vaccinate their children. Vaccination is safe and effective. All vaccines undergo long and careful review by scientists, doctors, and the federal government to make sure they are safe. Organizations such as the American Academy of Pediatrics, the American Academy of Family Physicians, and the Centers for Disease Control and Prevention all strongly support protecting children with recommended vaccinations. Vaccination protects others you care about, including family members, friends, and grandparents. If children aren’t vaccinated, they can spread disease to other children who are too young to be vaccinated or to people with weakened immune systems, such as transplant recipients and people with cancer. This could result in long-term complications and even death for these vulnerable people. We all have a public health commitment to our communities to protect each other and each other’s children by vaccinating our own family members. subscribe my channel https://www.youtube.com/channel/UC4GrKzQc0n-i8DsjH_ynkNA?view_as=subscriber google plus https://plus.google.com/102332871130341184209 twitter https://twitter.com/InsideHuman2?lang=en instagram https://www.instagram.com/insidehuman2018/?hl=en
