A search for long-lived balancing selection has found at least six regions of the genome where humans and chimpanzees share a combination of genetic variants. These human genetic variation dates back to a common ancestor with chimpanzees millions of years ago, before the species split.
Gene wars rage inside our cells, with invading DNA regularly threatening to subvert our human blueprint. Now, building on Nobel-Prize-winning findings, UC San Francisco researchers have discovered a molecular machine that helps protect a cell’s genes against these DNA interlopers.
A new report published in Psychological Science, a journal of the Association for Psychological Science, reveals that self-reported feelings of well-being — that is, overall happiness and satisfaction with life — tend to increase with age, but that a person’s overall level of well-being depends on when he or she was born.
You may want to ramp up your romance this year by sharing a candlelight dinner, a walk on the beach, or even the scent of a perfume, but will that help you find your perfect mate? For one wasp species, it only takes a whiff of his special love potion to know whether he’s “Mr. Right.”
New data from NASA's Chandra X-ray Observatory suggest a highly distorted supernova remnant may contain the most recent black hole formed in the Milky Way galaxy. The remnant appears to be the product of a rare explosion in which matter is ejected at high speeds along the poles of a rotating star.
Scientists at Washington University School of Medicine in St. Louis have identified a genetic mutation that may underlie common behaviors seen in some people with autism, such as difficulty communicating and resistance to change.
A new study from engineers at Rensselaer Polytechnic Institute and the University of California, Berkeley, pairs light and genetics to give researchers a powerful new tool for manipulating cells. Results of the study, published in the journal Nature Methods, show how blue light can be used as a switch to prompt targeted proteins to accumulate into large clusters.
Moderate intoxication may help a person notice minor changes in a visual scene, researchers at the University of Illinois at Chicago have found.
Ancient carbon trapped in Arctic permafrost is extremely sensitive to sunlight and, if exposed to the surface when long-frozen soils melt and collapse, can release climate-warming carbon dioxide gas into the atmosphere much faster than previously thought.
Shark attacks in the U.S. reached a decade high in 2012, while worldwide fatalities remained average, according to the University of Florida’s International Shark Attack File report released today.
Concerns and anxieties about one’s close relationships appear to function as a chronic stressor that can compromise immunity, according to new research.
Researchers at the University of Michigan’s Life Sciences Institute have found that amlexanox, an off-patent drug currently prescribed for the treatment of asthma and other uses, also reverses obesity, diabetes and fatty liver in mice.
If that headline doesn’t grab your attention, new research from Washington University in St. Louis’ Olin Business School on the “Psychological and Sexual Costs of Income Comparison in Marriage” should. The study shows that men married to women with higher incomes are more likely to use erectile dysfunction medication than their male breadwinner counterparts.
University of Alabama at Birmingham (UAB) nephrologists have reported for the first time in medical literature cases of acute kidney injury directly linked with synthetic marijuana use. The case studies are reported online in the Clinical Journal of the American Society of Nephrology and will appear in the March 2013 print edition of the journal.
Fishing communities living on the islands of Indonesia’s Karimunjawa National Park have found an important balance, improving their social well-being while reducing their reliance on marine biodiversity, according to the Wildlife Conservation Society and the University of Western Australia.
By identifying two genes required for transforming inorganic into organic mercury, which is far more toxic, scientists today have taken a significant step toward protecting human health.
NASA's Spitzer and Hubble space telescopes have teamed up to uncover a mysterious infant star that behaves like a strobe light.
So why are students’ perceptions of the T. rex stalled in the early 1900s, when the dinosaurs were depicted as upright, somewhat slow-moving tail draggers? A Cornell University research team sought answers after years of anecdotally observing students drawing the T. rex incorrectly.
People who grew up in states where it was legal to drink alcohol before the age of 21 are more likely to be binge drinkers later in life. Washington University researchers found that people who lived in states with lower minimum drinking ages weren’t more likely to consume more alcohol overall, but when they did drink, they were more likely to drink heavily.
A University of Delaware professor and collaborators in 9 other countries investigated why global consumers buy luxury goods. The reasons could alter how marketers operate.
The Air Force Office of Scientific Research has awarded Wu Feng, associate professor of computer science at Virginia Tech, and his colleagues a project to improve the simulation speed of micro air vehicles (MAVs), a class of unmanned aerial vehicles, using accelerator based supercomputers.
