Chinese Girl Receives Full Skull Reconstruction Via 3D Printing
ErnieKey writes: Doctors in China have just successfully performed a groundbreaking surgery on a 3-year-old little girl named Han Han. Han Han was suffering from congenital hydrocephalus which caused her head to grow to four times the normal size. If something wasn't done, she probably wouldn't have lived much longer. This is when surgeons at the Second People's Hospital of Hunan Province elected to remove a large portion of her skull and replace it with a 3d printed titanium mesh skull. The results were truly amazing, and Han Han is expected to make a full recovery. -
Problem Solver Beer Tells How Much To Drink To Boost Your Creativity
mrspoonsi writes When you've been stuck on a problem or that creative spark just won't come, the chances are you've turned to a cup of coffee to get things moving. A quick java infusion can certainly help, but studies also suggest that alcohol can also have a positive impact on your creative cognition. University of Illinois Professor Jennifer Wiley determined that a person's "creative peak" comes when their blood alcohol level reaches 0.075, lowering their ability to overthink during a task. Medical Daily reports that marketing agency CP+B Copenhagen and Danish brewery Rocket Brewing wanted to help drinkers reach their imaginative prime, so they decided to create their own beer to do just that. The result is The Problem Solver. It's a 7.1 percent craft IPA that its makers say offers a "refined bitterness with a refreshing finish." To ensure you reach the optimum creative level, the bottle includes a scale, which determines how much of the beer you need to drink based on your body weight. The agency does offer a word of warning though: "Enjoying the right amount will enhance your creative thinking. Drinking more will probably do exactly the opposite." -
Researchers Forecast the Spread of Diseases Using Wikipedia
An anonymous reader writes Scientists from Los Alamos National Laboratory have used Wikipedia logs as a data source for forecasting disease spread. The team was able to successfully monitor influenza in the United States, Poland, Japan, and Thailand, dengue fever in Brazil and Thailand, and tuberculosis in China and Thailand. The team was also able to forecast all but one of these, tuberculosis in China, at least 28 days in advance. -
America's Real Criminal Element: Lead
2muchcoffeeman writes "The cause of the great increase in violent crime that started in the 1960s and peaked in the 1990s may have been isolated: lead. This leads directly to the reason for the sharp decline in violent crime since then: lead abatement programs and especially the ban of tetraethyl lead as an anti-knock agent in gasoline starting in 1996. There are three reasons why this makes sense. First, the statistics correlate almost perfectly. Second, it holds true worldwide with no exceptions. Every country studied has shown this same strong correlation between leaded gasoline and violent crime rates. Third, the chemistry and neuroscience of lead gives us good reason to believe the connection. Decades of research has shown that lead poisoning causes significant and probably irreversible damage to the brain. Not only does lead degrade cognitive abilities and lower intelligence, it also degrades a person's ability to make decisions by damaging areas of the brain responsible for emotional regulation, impulse control, attention, verbal reasoning, and mental flexibility. Another thing that stands out: if you overlay a map showing areas with higher incidence of violent crime with one showing lead contamination, there's a strikingly high correlation." -
Why Girls Do Better At School
An anonymous reader writes "A new study explains why girls do better at school, even when their scores on standardized tests remain low. Researchers from University of Georgia and Columbia University say the variation in school grades between boys and girls may be because girls have a better attitude toward learning than boys. One of the study's lead authors, Christopher Cornwell, said, 'The skill that matters the most in regards to how teachers graded their students is what we refer to as "approaches toward learning." You can think of "approaches to learning" as a rough measure of what a child's attitude toward school is: It includes six items that rate the child's attentiveness, task persistence, eagerness to learn, learning independence, flexibility and organization. I think that anybody who's a parent of boys and girls can tell you that girls are more of all of that.' Cornwell went on about what effect this has had now that education has become more pervasive: 'We seem to have gotten to a point in the popular consciousness where people are recognizing the story in these data: Men are falling behind relative to women. Economists have looked at this from a number of different angles, but it's in educational assessments that you make your mark for the labor market. Men's rate of college going has slowed in recent years whereas women's has not, but if you roll the story back far enough, to the 60s and 70s, women were going to college in much fewer numbers. It's at a point now where you've got women earning upward of 60 percent of the bachelors' degrees awarded every year.'" -
Panda Blood May Hold Potent Assailant Against Superbugs
An anonymous reader writes "Pandas have long been the face of conservation efforts by environmental activists, but a recent finding may boost even further the need for pandas to evade extinction. Researchers have discovered a powerful antibody in panda blood that could serve as the next frontier in the fight against increasingly prevalent superbugs. The compound is called cathelicin-AM. Discovered when researchers analyzed the creatures' DNA, it has been found to kill fungus and bacteria. It is believed that the antibiotic is released to protect the animal from infections in the wild and, in studies, it has been found to kill both standard and drug-resistant strains of microbes and fungi. The compound also worked extremely quickly, killing off strains of bacteria in just an hour, while conventional antibiotics needed six." -
Bangladesh Slaughters 150,000 Birds After Worst H5N1 Virus Outbreak In 5 Years
An anonymous reader writes in with news about a bird flu outbreak in Bangladesh. "At least 150,000 chickens and 300,000 eggs have been destroyed at a giant poultry farm near Dhaka in Bangladesh after the major outbreak of avian flu was detected last week, officials said Wednesday. This season's bird flu outbreak was the worst in five years. Officials at Bay Agro at Gazipur detected the deadly H5N1 flu strain 25 miles (40 kilometers) north of Dhaka on Monday after dozens of birds died, which had prompted the poultry company to send samples to a laboratory for testing. 'There are about 150,000 chickens at the farm. We have already killed and destroyed 120,000 chickens and we will kill the rest today,' livestock department director Mosaddeq Hossain said, according to AFP. Hossain said that it was the worst avian flu outbreak in five years." -
FDA Closer To Approving Biotech Salmon
An anonymous reader writes with a story about the possibility of genetically engineered salmon showing up on your table. "A controversial genetically engineered salmon has moved a step closer to the consumer's dining table after the U.S. Food and Drug Administration said Friday the fish didn't appear likely to pose a threat to the environment or to humans who eat it. AquAdvantage salmon eggs would produce fish with the potential to grow to market size in half the time of conventional salmon. If it gets a final go-ahead, it would be the first food from a transgenic animal - one whose genome has been altered - to be approved by the FDA." -
Human Cloning Possible Within 50 Years, Nobel Prize-Winning Scientist Claims
An anonymous reader writes in with a story about the possibility of having another you in the future. "Human cloning could happen within the next half century, claims a Nobel Prize-winning scientist. Sir John Gurdon, the British developmental biologist whose research cloning frogs in the 1950s and 60s led to the later creation of Dolly the sheep in 1996, believes that human cloning could happen within the next 50 years. He said that parents who lose their children to tragic accidents might be able to clone replacements in the next few decades. Gurdon, who won this year's Nobel Prize for Physiology or Medicine, said that while any attempts to clone a human would likely raise complex ethical issues, he believes that in the near future people would overcome their concerns if cloning became medically useful." -
Single Microbe May Have Triggered the "Great Dying"
An anonymous reader writes with an excerpt from Medical Daily about a new theory for what triggered the "Great Dying: " "Researchers believe that they may finally know why the event occurred, but the theory is not without controversy. There are several theories, including the possibility of a meteorite hitting the planet. Previously, most researchers believed that the Permian mass extinction was a result of a series of volcanic eruptions in what is now Siberia. ... However, Daniel Rothman from the Massachusetts Institute of Technology is floating around a different theory. As he presented in a meeting for the American Geophysical Union, he believes that the mass extinction could have been caused by something much smaller. His theory is that the extinction was caused by a single strain of bacteria." -
Scientists Make Fish Grow "Hands" In Experiment Revealing How Fins Became Limbs
An anonymous reader writes "While fossils have long shown that limbs evolved from fins, scientists have shown live in the laboratory how the transition may have happened. Researchers said that the new study published in the journal Developmental Cell offers evidence revealing that the development of hands and feet occurred through the acquisition of new DNA elements capable of activating specific genes." -
Spinal Fluid Chemical Levels Linked To Suicidal Behavior
An anonymous reader writes "For the first time, researchers have found that a chemical in the brain called glutamate is linked to suicidal behavior. While previous research and drugs have targeted serotonin to fight severe depression, this study shows that more attention should be paid to this chemical." -
Humans Have Been Eating Cheese For At Least 7,500 Years
An anonymous reader writes "Researchers have found conclusive evidence for the first time that humans have been making cheese since the 6th millennium BC." -
Four Cups of Coffee A Day Cuts Risk of Oral Cancer
An anonymous reader writes "Coffee may help lower the risk of developing oral and pharyngeal cancer and of dying from the disease. The study, published in the American Journal of Epidemiology, was conducted using the Cancer Prevention Study II. The large cohort study began in 1982 by the American Cancer Society. Researchers were able to examine 968,432 men and women, none of whom had cancer at the time of their enrollment in the study." Four or more cups a day lowered the risk of getting oral cancers by a whopping 49%. -
Newly Developed RNA-Based Vaccine Could Offer Lifelong Protection From the Flu
An anonymous reader writes "A new experimental flu vaccine made out of messenger RNA that may work for life is now being developed. German researchers said on Sunday that the vaccine, made of the genetic material that controls the production of proteins, protected animals against influenza and, unlike traditional vaccines, it may work for life and can potentially be manufactured quickly enough to stop a pandemic (abstract)." -
Implant Translates Written Words To Braille, Right On the Retina
An anonymous reader writes "For the first time, blind people could read street signs with a device that translates letters into Braille and beams the results directly onto a person's eye." According to the article, "In a trial conducted on a single patient who already used the [predecessor] device, the person was able to correctly read Braille letters up to 89 percent of the time, and most of the inaccuracy appeared when the participant misread a single letter. The user was able to read one word a second." -
Research Suggests Apes and Humans Separated By a Single Gene
An anonymous reader writes "Researchers believe that they have found the definitive difference between humans and other primates, and they think that the difference all comes down to a single gene." -
Sequenced Pig Genome Could Help Combat Human Diseases
An anonymous reader writes "Scientists announced Wednesday that they have mapped the entire genome of the domestic pig, revealing that besides providing tasty bacon and sausages, the animal may also be useful in fighting human diseases. The study published in the journal Nature found that pigs and humans share 112 DNA mutations that have previously been linked to diseases like obesity, diabetes, dyslexia, Parkinson's and Alzheimer's, according to US and European researchers. Researchers said that because pigs share many of the same complex genetic diseases as humans, the animals would serve as excellent models for studying the underlying biology of human disease." -
Brain Scans Show the Impact of Neglect On a Child's Brain Size
An anonymous reader writes "A shocking comparison of brain scans from two three-year-old children reveals new evidence of the remarkable impact a mother's love has on a child's brain development. The chilling images reveal that the left brain, which belongs to a normal 3-year-old, is significantly larger and contains fewer spots and dark 'fuzzy' areas than the right brain, which belongs to that of a 3-year-old who has suffered extreme neglect. Neurologists say that the latest images provide more evidence that the way children are treated in their early years is important not only for the child's emotional development, but also in determining the size of their brains. Experts say that the sizeable difference in the two brains is primarily caused by the difference in the way each child was treated by their mothers." -
States Face Huge Task In Tracking Meningitis-Tainted Drugs
An anonymous reader writes "Confronted with a growing meningitis scare, states are coming under enormous pressure to meet federal requests that they contact more than 1,000 hospitals and clinics that received any injectable drugs from the company at the center of the deadly outbreak." -
Lawsuit Challenges New York Sugary Drink Ban
An anonymous reader writes "Soda makers, along with other trade organizations, filed a lawsuit Friday challenging the New York soda ban that is about to be implemented in the city. 'Last month, the board voted eight to zero, with one abstention, to ban restaurants, mobile food carts, delis and concessions at movie theaters, stadiums and arenas from selling sugary drinks in cups or containers larger than 16 ounces. The ban, designed to reduce obesity, is slated to begin March 12. ... The lawsuit also claims that new regulations are “arbitrary and capricious,” violating a section of the New York Civil Laws and Rules. Opponents have specifically said it’s unfair that convenience stores, including 7-Eleven and its famous Big Gulp drink, would be exempt.'" -
520-Million-Year-Old Arthropod May Have Had the First Modern Brain
An anonymous reader writes "Scientists say that the recently discovered 520 million year old insect brain, the oldest brain ever discovered in an arthropod, is surprisingly complex for its age, and may be the earliest example on record of a modern brain structure. Hailed as a 'transformative discovery,' researchers said that the 3-inch-long fossilized extinct arthropod found in Yunnan Province, China, shows that insects evolved to have complex brains significantly earlier than previously thought. Researchers said that the fossilized brain, which looks very similar to brains of modern insects, may provide a missing link that offers new insight on the evolutionary history of arthropods, a group of invertebrates that includes insects, spiders and crustaceans." -
DNA Analysis Probes the End of Human-Neanderthal Sex
An anonymous reader writes "Modern Europeans may have interbred with Neanderthals as recently as 37,000 years ago, after modern humans with advanced stone tools expanded out of Africa, according to a new study. In an attempt to understand why the Neanderthals are more closely related to people from outside of Africa, researchers from Harvard and the Max Planck Institute estimated that while the last sex between Neanderthals and modern humans may have occurred 37,000 to 86,000 years ago, it is most likely that it occurred 47,000 to 65,000 years ago." -
Woman Successfully Grows Ear From Arm
An anonymous reader writes "In 2008, Sherrie Walters, now 42 years old, discovered that she had rapidly spreading basal cell cancer in her ear. The disease is a type of skin cancer. The doctors pursued an aggressive treatment to combat the destructive disease, removing her ear, part of her skull, and her left ear canal. Though Walters was left without an ear, she was still able to hear with the help of a special hearing aid. A few months ago, doctors from the renowned Johns Hopkins University in Baltimore decided to try a new procedure on Walters. Using cartilage from her rib, the doctors stitched a new ear to match her right one. Then their creation was implanted under the skin of her forearm, where the ear grew for months. ...Doctors attached the ear and blood vessels surgically. Another surgery, conducted this week, gave the ear shape and detail. Dr. Patrick Byrne, a revered plastic and reconstructive surgeon, says that after the swelling goes down and the ear heals, Walters will have an ear that both looks and functions normally." -
Scientists Invent Electronics That Dissolve In the Body
An anonymous reader writes in with a story about some new electronics that are designed to melt in your body not in your hand. "Scientists have created ultra-thin electronic devices that can 'melt away' in the body once their job is done. A new study published in the journal Science, details how scientists have created a tiny, fully functional electronic device capable of vanishing within their environment, like in the body or in water, once they are no longer needed or useful. There are already implants that dispense drugs or provide electrical stimulation but they do not dissolve. The latest creation is an early step in a technology that may benefit not only medicine, like enabling the development of medical implants that don't need to be surgically removed or the risk of long-term side effects, but also electronic waste disposal." -
Fast-Food Logos Burned Into Pleasure Center of Children's Brains
bbianca127 writes "A study has found that fast-food logos are branded into the minds of children at an early age, perhaps fueling the U.S.'s obesity epidemic. The study showed children 60 logos from popular food brands and 60 logos from popular non-food brands. Researchers found that, when shown images of fast-food brands, the parts of kids' brains linked with pleasure and appetite lit up. This is concerning because marketers tap into those portions of the brain long before children develop self-control, and most foods marketed to kids are high in calories, sugar, sodium, and fat." -
180k-Year-Old Mutation Allowed Humans To Become Vegetarians, Move Out of Africa
An anonymous reader writes "Early humans were able to move from Africa after a single genetic mutation allowed them to become vegetarians, scientists claim. The switch, which allowed humans to process vegetables, meant that humans were able to move away from water sources and spread across the continent. A team of geneticists compared DNA sequences from a variety of people around the world to see how different populations relate to one another and when they have gone their separate ways. The scientists found that a key genetic variant gave humans the ability to convert fats from plants into essential nutrients for the brain." -
Monkeys Made Smarter With Prosthetic Device
An anonymous reader writes "Scientists have successfully restored and, in some cases, enhanced decision-making ability in brain-damaged monkeys on cocaine by connecting a prosthetic device to their brains. 'In the study, the scientists trained five monkeys to match multiple images on a computer screen until they were correct 70 to 75 percent of the time. First, an image appeared on the screen, which the animals were trained to select using a hand-controlled cursor. The screen then went blank for up to two minutes, followed by the reappearance of two to eight images, including the initial one, on the same screen. When the monkeys correctly chose the image they were shown first, the electronic prosthetic device recorded the pattern of neural pulses associated with their decision by employing a multi-input multi-output nonlinear (MIMO) mathematical model, developed by researchers at the University of Southern California. In the next phase of the study, a drug known to disrupt cognitive activity, cocaine, was administered to the animals to simulate brain injury. When the animals repeated the image-selection task, their decision-making ability decreased 13 percent from normal. However, during these "drug sessions," the MIMO prosthesis detected when the animals were likely to choose the wrong image and played back the previously recorded "correct" neural patterns for the task. According to the study findings, the MIMO device was exceedingly effective in restoring the cocaine-impaired decision-making ability to an improved level of 10 percent above normal, even when the drug was still present and active.'" -
California's Unspoken Health Problem: Brain Parasites
An anonymous reader writes "Sunnyvale, California is a town 40 miles outside of San Francisco, in the Bay Area. As in most of California, the weather is mild, and the winters are short, even sometimes warm. On December 20, Sara Alvarez took her youngest child for a walk in the park in town. As daylight faded, Alvarez lost feeling in her right leg, then her left foot. Her body became numb, and she became weak. At 10:15 pm, her husband drove her to a hospital in Redwood City, about 20 minutes away from their town. There, over the course of Christmas, doctors batted around diagnoses: tumor, cancer. Finally, Alvarez received a brain scan that revealed the truth: neurocysticercosis, a calcified tapeworm in her brain (link contains images of brain surgery)." -
CDC Says 10,000 At Risk of Hantavirus In Yosemite Outbreak
An anonymous reader writes "Some 10,000 people who stayed in tent cabins at Yosemite National Park this summer may be at risk for the deadly rodent-borne hantavirus according to the U.S. Centers for Disease Control." -
Promiscuity Alters DNA and Boosts Immunity In Mice
An anonymous reader writes "Scientists from the University of California, Berkeley found that promiscuous mice have significantly stronger immune systems than monogamous mice, suggesting that promiscuous mice may have developed more robust immunity to protect them against the disease-causing bacteria they are exposed to from mating with multiple partners." -
Scientists Find Gene That Predicts Happiness In Women
An anonymous reader writes "For reasons that scientists have not conclusively determined, women are happier than men. And now, researchers think that they may have pinpointed one of the reasons for that. They have found a gene in women that predicts the level of happiness in women. 'After controlling for various factors, ranging from age and education to income, the researchers found that women with the low-expression type of MAOA were significantly happier than others. Compared to women with no copies of the low-expression version of the MAOA gene, women with one copy scored higher on the happiness scale and those with two copies increased their score even more. While a substantial number of men carried a copy of the "happy" version of the MAOA gene, they reported no more happiness than those without it.'" -
Forensic Test Predicts Eye and Hair Color From DNA
An anonymous reader writes "A forensic test that has been developed to help police nab perpetrators of crimes can predict a suspect's eye color, hair color, and ethnic origin. The test's ability and the science behind it has been outlined in Forensic Science International: Genetics (abstract). Developed by Susan Walsh and other researchers from the Netherlands, Greece, and Poland, the test uses phenotypes from DNA to ... predict a suspect's appearance using 'low amounts of template DNA, as well as degraded DNA,' which means that the DNA does not need to be perfect in order for the system to read it." -
Man With World's Deepest Voice Can Hit Infrasonic Notes
An anonymous reader writes "The man who holds the Guinness record for the world's lowest voice can hit notes so low that only animals as big as elephants are able to hear them. American singer Tim Storms, who also has the world's widest vocal range, can reach notes as low as G-7 (0.189Hz), an incredible eight octaves below the lowest G on the piano." -
Study Suggests You Can Learn New Things In Your Sleep
bbianca127 writes "Researchers studied classical conditioning in 55 study participants while sleeping or awake. According to the article, 'Classical conditioning teaches a person or animal to associate one stimulus with another.' The researchers paired tones with scents; when they played a tone, they would let out a particular scent while the participants were sleeping. They found that the participants would make the association between the tones and scents even while awake." -
Music Memories Stored In Different Part of Brain Than Other Memories
An anonymous reader writes "Scientists have long believed that the ability to learn and appreciate music was stored in a different part of the brain than other types of memories. Now, researchers in Berlin think that they have concluded that theory. Dr. Christoph J. Ploner, Carson Finke, and Nazli Esfahani at the Department of Neurology at the Virchow campus in Berlin, Germany have examined a man who has lost all of his memories but has retained his ability to remember and learn songs." -
California Wants Genetically Modified Foods To Be Labelled
bbianca127 writes "In November, California will be voting on Proposition 37. The proposition would mandate putting labels on foods that have been genetically modified. While supporters of the proposition think that consumers deserve to know what they're eating, opponents call it 'anti-science' and have donated $25 million to defeating the measure. From the article: 'Unsurprisingly, the battle has gotten very expensive, very quickly. Agribusinesses and food manufacturers have donated a total of $13 million toward defeating the measure, bringing the total up to $25 million in the coffers of those proposing the proposition. In comparison, the organic farmers and environmentalists who support the proposition have managed to raise less than a tenth of that total amount.'" -
Mexico Kills 8 Million Chickens To Contain H7N3 Virus
An anonymous reader writes "Mexico has so far slaughtered eight million chickens and vaccinated 66 million more in an effort to contain a bird flu outbreak in the west of the country, officials said Tuesday. The country's agriculture ministry had identified the diseased chickens during the vaccination process in the Los Altos region of Jalisco state, which led to the destruction of the H7N3-carrying birds." -
Overconfidence May Be a Result of Social Politeness
An anonymous reader writes "Joyce Ehrlinger from Florida State University has researched this very phenomenon, and has led her to present a paper called 'Polite But Not Honest: How an Absence of Negative Social Feedback Contributes to Overconfidence' at the American Psychological Association's annual conference in Orlando on Friday. Social norms, Ehrlinger says, are the reason that we are averse to giving negative feedback. Her research recreated everyday social situations in which we hold back from giving our own negative views." -
Goodbye, IQ Tests: Brain Imaging Predicts Intelligence Levels
An anonymous reader writes "Research from Washington University in St. Louis has identified variations in brain scans that they believe identify portions of the brain that are responsible for intelligence (abstract). As suspected (and as explained by cartoons) brain size does play a small role; they said that brain size accounts for 6.7 percent of variance in intelligence. Recent research has placed the brain's prefrontal cortex, a region just behind the forehead, as providing for 5 percent of the variation in intelligence between people. The research from Washington University targets the left prefrontal cortex, and the strength of neural connections that it has to the rest of the brain. They think these differences account for 10 percent of differences in intelligence among people. The study is the first to connect those differences to intelligence in people." -
Oldest DNA Recovered From 7,000-Year-Old Skeletons In Spain
An anonymous reader writes "Researchers published a paper in the current issue of Current Biology detailing their analysis of DNA from 7,000-year old cavemen in northern Spain. From the article: 'The bones of the two young adult males were found in a cave in the Cantabarian mountain range in 2006 by a handful of explorers, 4,920 feet above sea level. The cold atmosphere is what preserved the DNA in the remains of the two bodies. The cavemen lived during the Mesolithic period and were hunter-gatherers, as determined by an ornament one of the skeletons was holding. They have named the two skeletons Braña1 and Braña2 after the Braña-Arintero site in which they were discovered. They were in near-perfect condition.'" -
Human Stem Cell Transplants Successfully Reversed Diabetes In Mice
An anonymous reader writes "Scientists successfully reversed diabetes in mice by transplanting mice human stem cells into mice in a discovery that may lead to way to finding a cure for a disease that affects 8.3 percent of the U.S. population. ... In an experiment designed to mimic human clinical conditions, researchers were able to wean diabetic mice off of insulin four months after the rodents were transplanted with human pancreatic stem cells (abstract). [They] were able to recreate the 'feedback loop' that enabled insulin levels to automatically rise or fall based on the rodents' blood glucose levels. Additionally, researchers found that the mice were able to maintain healthy blood sugar levels even after they were fed large quantities of sugar. After several months, researchers removed the transplanted cells from the mice and found that the cells had all the markings of normal insulin-producing pancreatic cells." -
Erasing Details Of Bad Memories
An anonymous reader writes "People can be trained to forget specific details associated with bad memories, according to breakthrough findings that may lead the way for the development of new depression and post-traumatic stress disorder therapies. New study (abstract), published in the Journal of Experimental Psychology: Learning, Memory and Cognition, reveals that individuals can be taught to forget personal feelings associated with an emotional memory without erasing the memory of the actual event." -
Details of the Second Controversial Mutant Bird Flu Study Finally Published
An anonymous reader writes "The second of the two controversial bird flu studies once considered too risky to publish in fears that they would trigger a potentially devastating global influenza epidemic was published Thursday. The study describes how scientists created H5N1 virus strains that could become capable of airborne transmission between mammals. Scientists said that the findings, which had been censored for half a year, could help them detect dangerous virus strains in nature." -
Belief In Hell Predicts a Country's Crime Rates Better Than Other Factors
An anonymous reader writes "Religion is often thought of as psychological defense against bad behavior, but researchers have recently found that the effect of religion on pro-social behaviors may actually be driven by the belief in hell and supernatural punishment rather than faith in heaven and spiritual benevolence. In a large analysis of 26 years of data consisting of 143,197 people in 67 countries, psychologists found significantly lower crime rates in societies where many people believe in hell compared to those where more people believed in heaven." -
Vein Grown From Her Own Stem Cells Saves 10-Year-Old
An anonymous reader writes in with a story about a milestone in stem cell medicine. "A ten year old girl became the first person in the world to get a major blood vessel replaced by one grown using her own stem cells. The 10-year-old from Sweden had a blockage of a vein from her liver. The doctors decided to give her a new vein instead of a liver transplant or giving her a vein from her own body, Associated Press reported. The team from University of Gothenburg first took 9 cm vein segment from a dead man and stripped all living cells from it, leaving behind only a protein structure. They later reconstructed the vein by using cells from the girl's own bone marrow. The new graft was then put in the girl's body two weeks later." -
The Link Between Genius and Insanity
An anonymous reader writes in a story about the link between certain mental illnesses and high intelligence. "Genius and insanity may actually go together, according to scientists who found that mental illnesses like schizophrenia and bipolar disorder are often found in highly creative and intelligent people. The link is being investigated by a group of scientists who had all suffered some form of mental disorder. Bipolar sufferer Kay Redfield Jamison, a clinical psychologist and professor at Johns Hopkins University School of Medicine, said that findings of some 20 or 30 scientific studies confirms the idea of the 'tortured genius' or 'mad scientist.'" -
Certain 'Personality Genes' Correlate With Longevity, Says Study
An anonymous reader writes "People who are outgoing, optimistic, easygoing, and have a good sense of humor and a large social network are likely to live longer than others who don't possess these personality traits, according to new research (abstract). The study reveals how saying, 'It's in their genes' could refer to more than just genetic variations that give a physiological advantage, like having high levels of HDL ('good') cholesterol, because people with positive personality traits appear to live longer than those who do not." -
Depressed People Surf the Web Differently
An anonymous reader sends this excerpt from Medical Daily: "Researchers led by Sriram Chellappan from the Missouri University of Science and Technology, collected internet usage data from 216 college students enrolled at the university. The usage data was collected anonymously without interfering with the student’s normal internet usage for a month. The students were tested to see if they had symptoms of depression and analyzed internet usage based on the results. Depressed students tended to use the internet in much different ways than their non-depressed classmates. Depressed students used file-sharing programs, like torrents or online sharing sites, more than non-depressed students (PDF). Depressed students also chatted more and sent more emails out. Online video viewing and game playing were also more popular for depressed students." -
Paralyzed Man Regains Hand Function After Breakthrough Nerve Rewiring Procedure
An anonymous reader writes "A 71-year-old man who became paralyzed from the waist down and lost all use of both hands in a 2008 car accident has regained motor function in his fingers after doctors rewired his nerves to bypass the damaged ones in a pioneering surgical procedure, according to a case study published on Tuesday."
