December 18, 2012 More than 100 federally owned primates have been the subject of controversy. In 2010, the National Institutes of Health made arrangements to move some retired chimpanzees back into the research, spurring protests. But the NIH eventually decided to accept an independent assessment that found there is almost no scientific need for chimps in biomedical research.
December 17, 2012 Secretions from a brown frog's skin contain chemicals that might be useful in fighting bacteria. Russian researchers are cataloging compounds in the slimy goo. Although the odds against them are long, the researchers hope their work will aid the search for new drugs.
December 13, 2012 Communing with nature has long helped artists get their creative juices flowing. A neuroscientist wondered how backpacking trips without any electronic devices might change the way people solved problems.
December 12, 2012 A roundup of the medical evidence by a group of independent researchers suggest that giving babies sugar water before injections can help comfort them. But the latest analysis is less enthusiastic about the approach than a previous review.
December 10, 2012 The barbs on porcupine quills help them pierce the skin. If the bumpy needles work so well for the big rodents, couldn't they they also help doctors and nurses giving injections? Designers of medical devices are looking to try the porcupine approach.
December 3, 2012 With growing controversy over the risk of permanent brain injury in contact sports, researchers find an association between repetitive head trauma and brain disease in samples taken from deceased athletes. Many were professional football players.
November 23, 2012 What made Einstein a genius? Maybe his weirdly curvy brain had something to do with it. Scientists have recently analyzed photos from the 1950s to try to figure out what made the genius tick.
November 21, 2012 CPRPrevious research has found that patients with online access to their doctors made fewer trips to the doctor's office. But a large, just-published study shows just the opposite: Patients who can email their physicians may schedule more visits.
November 15, 2012 Scientists have found rappers and jazz musicians use their brains in similar ways when it comes to improvisation. Brain scans show distinct differences in which parts of the brain are most active during rap performances of memorized pieces compared with those that are done freestyle.
November 8, 2012 When we listen to a new musical phrase, it is the parts of the brain that control muscle movement, not areas involved in hearing, that help us remember what we've heard. Keeping the notes in order is a little like getting your muscles to move at the right time.
November 7, 2012 Scientists are charged with pushing back the boundaries of ignorance, with exploring nature's unanswered questions. Commentator Marcelo Gleiser says the system that allocates funding for research can also limit the range of questions asked by the scientific community.
October 19, 2012 Could prebiotics, the food for the good bacteria known as probiotics, have more benefits than a dose of the microbes, particularly for people with serious health problems like preemies? A researcher working with pigs is trying to figure that out.
October 12, 2012 Oral bacteria may be determined by environment, not genes, scientists say. That's different from other parts in the body, like the gut, where bacteria may be influenced by genome or immune system.
