Too much turkey: What happens when you overeat? (video)

How does glass transition from a liquid to its familiar solid state? How does this common material transport heat and sound? And what microscopic changes occur when a glass gains rigidity as it cools? A team of researchers at NYU's Center for Soft Matter Research offers a theoretical explanation for these processes in Proceedings of the National Academy of Sciences. Our understanding of glasses as they change state is relatively limited. This is because, unlike other materials such as metals, their constituent particles--which can be as small as a billionth of a meter ...

People who see their group as more homogenous - for instance, the more one thinks Americans are similar to each other - are less likely to be influenced by external terrorist threat alerts, according to research from NYU's Steinhardt School of Culture, Education, and Human Development. "Among people who viewed their group to be homogeneous, external threat did not translate to higher perceived threat, and they did not influence beliefs about the legitimacy of the U.S. military intervention in Iraq," said study author Rezarta Bilali, assistant professor of psychology and ...

ANN ARBOR--The medical community may be inadvertently creating a new generation of illegal, recreational drug users by prescribing anti-anxiety or sleep medications to teenagers, say University of Michigan researchers. Teens prescribed anxiety or sleep medications are up to 12 times more likely to abuse those drugs than those who had never had a prescription, either by using someone else's prescription pills or to get high or experiment, according to a study from the U-M School of Nursing. Nearly 9 percent of the 2,745 adolescent study participants had received ...

A team of scientists from Arizona State University's Biodesign Institute and IBM's T.J. Watson Research Center have developed a prototype DNA reader that could make whole genome profiling an everyday practice in medicine. "Our goal is to put cheap, simple and powerful DNA and protein diagnostic devices into every single doctor's office," said Stuart Lindsay, an ASU physics professor and director of Biodesign's Center for Single Molecule Biophysics. Such technology could help usher in the age of personalized medicine, where information from an individual's complete DNA ...

SAN FRANCISCO (November 24, 2014) --A team of scientists, including researchers from the California Academy of Sciences, has reconstructed a detailed "tree of life" for turtles. The specifics of how turtles are related--to one another, to other reptiles, and even to dinosaurs--have been hotly debated for decades. Next generation sequencing technologies in Academy labs have generated unprecedented amounts of genetic information for a thrilling new look at turtles' evolutionary history. These high-tech lab methods revolutionize the way scientists explore species origins and ...

Members of the public in sub-Saharan Africa who are carriers of the hereditary disease sickle cell disease must be educated aggressively through public health campaigns to raise awareness of the risks of parenting offspring with the disease if their partner is also a carrier, according to research published in the International Journal of Medical Engineering and Informatics. There are many physical and emotional public health components of sickle cell disease, explains William Ebomoyi of the Department of Health Studies College of Health Sciences, Chicago State University, ...

A collaboration between NEC Electronics Samsung and several academic centres in China and Iran, is investigating how software-defined cellular networking might be used to give smart phone users the next generation of super-superfast broadband, 5G. They provide details in the International Journal of Communication Networks and Distributed Systems. Currently, the fourth generation of mobile phone connection technology, 4G, in as far as it has been adopted provides broadband-type connectivity for enabled devices such as smart phones, tablet computers, laptops and other gadgets ...

WOODS HOLE, Mass.--David Johnson was standing in a salt marsh on the northern Massachusetts coast when he saw a fiddler crab, Uca pugnax, nearly 50 miles north of its supposed natural range. The migration north of this charismatic crab with the big, waving claw may be yet another sign of climate change. Johnson, then a scientist at the Marine Biological Laboratory (MBL) Ecosystems Center, has published his observations in the Journal of Crustacean Biology. The fiddler crab is an attention-getting crustacean; the males have an oversized claw that they use to attract a ...

VIDEO: The most detailed aerodynamic simulation of hummingbird flight conducted to date demonstrates that it achieves its aerobatic abilities through a unique set of aerodynamic forces more closely aligned to those... Click here for more information. The sight of a tiny hummingbird hovering in front of a flower and then darting to another with lightning speed amazes and delights. But it also leaves watchers with a persistent question: How do they do it? Now, the most detailed, ...

Over a million US military veterans lacked healthcare coverage in 2012, according to new estimates published in The Lancet. While many people believe that all veterans are covered by the Veterans Affairs health care system, less than half (8.9 million) of the 22 million veterans in the US are covered by VA health benefits, and most veterans are covered by private health insurance. Uninsured veterans are more likely to be young, single, African American, and veterans of Iraq and Afghanistan. However, the authors of this viewpoint estimate that universal health coverage ...
