December 2, 2013 The administration is pledging $100 million toward a project to stop HIV infections once and for all. There's growing optimism among scientists that it may be possible to get patients' immune systems to control HIV without drugs, or even to eliminate the virus from the cells of infected people someday.
December 2, 2013 Left-handedness has been linked to everything from early death to schizophrenia over the past 150 years. While the associations spark curiosity and sometimes concern, it's been difficult to draw solid scientific conclusions, one way or the other.
November 25, 2013 What would you get if you challenged Ph.D. students to explain their work through dance? You'd get this: 31 creative, fun, silly and educational videos. Let's salsa to some serious research!
November 22, 2013 Food safety researchers in California are trying to find out how long E. coli in raw manure spread on a field might survive on a spinach farm. They're tweeting about it, too.
November 21, 2013 Newborns showed signs they're aware of and feel ownership over their bodies. Scientists measured how long babies watched a video of another baby being stroked on the face with a paintbrush in a variation on old psychology experiment.
November 15, 2013 The authors found that for each degree of separation from a homicide victim, one's odds of also being murdered went down by 57 percent.
November 15, 2013 Day after day, workers at Michigan State University care for and feed colonies of evolving bacteria. The original microbes have produced more than 50,000 generations in the 25 years since the experiment began. Despite predictions the bacteria might someday reach a point where they would evolve no more, the results show they keep changing.
November 7, 2013 Doctors have long overlooked a tiny band that connects two bones in the knee. Now Belgian surgeons say that's a mistake. The obscure structure is a full-fledged ligament. When it malfunctions, people recovering from anterior cruciate ligament injuries may run into trouble.
November 6, 2013 A research chemist applied his analytical smarts to his son's eye cancer. By analyzing family photos starting with some taken just a few days after birth, the dad found that signs of retinoblastoma, a rare eye cancer, could be detected quite early.
October 31, 2013 A monkey virus that's a stand-in for HIV plummeted to undetectable levels when animals got potent antibodies of a type recently discovered in some humans. A single antibody injection was enough to do the job.
October 11, 2013 Why is kissing found in practically every culture? A kiss can convey passion, love and, perhaps subconsciously, a veritable catalog of information about the worthiness of a potential mate. So much for romance.
October 11, 2013 Journal editors would usually require researchers to disclose the genetic sequences needed to make a toxin that is the subject of a scientific paper. But the requirement was waived in the case of a new botulinum toxin because of the security risk.
October 10, 2013 A lack of funding to labs is likely to mean an early death for thousands of mice used in scientific and medical research. The loss of specialty mice, many of which have genes that can cause them to develop versions of human diseases, is especially troubling to scientists — and expensive.
October 9, 2013 The three scientists sharing the 2013 Nobel Prize for chemistry developed computerized tools for studying complex molecules, such as enzymes and the photosynthesis machinery. These techniques allow engineers to design drugs and new chemical reactions more quickly and cheaply.
October 8, 2013 While the shutdown of the federal government means some research facilities have gone dark, commentator Adam Frank says the real threat to our national interest is the possibility that generations of would-be scientists will be lost to other pursuits if the funding to train new generations of scientists dries up.
