A research team from Duke University in North Carolina has recreated autistic mice by mutating the gene which controls production of the protein, Shank3. The single protein may trigger autistic spectrum disorders by disrupting communication between brain cells, BBC News is reporting. Autism affects the ability of children and adults to communicate and interact socially and has varying degrees of severity. Hundreds of genes linked to the condition have been found. However the precise...

(Ivanhoe Newswire)"” From overworked professionals to over-extended students, everyone worries about how much sleep they're getting. A new study from Duke University has shown yet another consequence of not sleeping enough: sleep deprivation can lead to a more optimistic outlook, resulting in riskier decisions. Using a functional MRI, scientists showed that a lack of sleep increases brain activity in the brain regions that assess positive outcomes while decreasing activity in the...

The powers that be in Las Vegas figured out something long before neuroscientists at two Duke University medical schools confirmed their ideas this week: Trying to make decisions while sleep-deprived can lead to a case of optimism. The scientists showed, using a functional MRI, that a night of sleep deprivation leads to increased brain activity in brain regions that assess positive outcomes, while at the same time this deprivation leads to decreased activation in the brain areas that process...

Humans share 98.7 percent of our DNA with chimpanzees, but we share one important similarity with one species of chimp, the common chimpanzee, that we don't share with the other, the bonobo. That similarity is violence. While humans and the common chimpanzee wage war and kill each other, bonobos do not. "There has never been a recorded case in captivity or in the wild of a bonobo killing another bonobo," notes anthropologist Brian Hare. Hare is an assistant professor in evolutionary...

A Duke University team has seen for the first time how soft polymers, such as wire insulation, can break down under exposure to electrical current.Researchers have known for decades that polymers, such those insulating wires, may break down due to deformation of the polymers. But the process had never been seen.In a series of experiments, Duke University engineers have documented at the microscopic level how plastic deforms to breakdown as it is subjected to ever-increasing electric voltage....

Why is it that the same teams seem to dominate the annual men's collegiate basketball tournament? For that matter, why does the same small group of institutions seem to top annual best-college rankings? According to a theory developed by a Duke University engineer, these hierarchies are not only natural, but predictable. Just as continually growing streams flow into a larger river, or smaller and smaller branches grow out from a single tree trunk, examples of these hierarchies abound in the...

High-resolution images from a laser-based tool developed at Duke University could help doctors better diagnose melanoma, the deadliest form of skin cancer, while potentially saving thousands of lives and millions of dollars in unnecessary healthcare costs each year. The tool probes skin cells using two lasers to pump small amounts of energy, less than that of a laser pointer, into a suspicious mole. Scientists analyze the way the energy redistributes in the skin cells to pinpoint the...
