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.
October 3, 2012 Ultraviolet light can burn your skin and raise the risk for skin cancer. New research has helped uncover how the rays can weaken skin's outer layer, compromising its ability to protect the body.
October 1, 2012 Biomedical researchers believed that most retractions of published studies were the result of honest errors. An analysis of retractions over four decades finds that's not the case.
September 27, 2012 Using silicon, magnesium and a special type of silk, scientists have created electronic circuits that dissolve in liquid. Electronics like these could be useful in future implantable medical devices.
September 25, 2012 Korean researchers have found that eunuchs who worked for kings in ancient royal courts lived longer, on average, than other males who were in the inner circle. The provocative findings fit with other work that has shown an inverse link between longevity and reproduction: the greater the fertility, the shorter the life span.
September 24, 2012 They found 40 or so key differences — all potential targets for cleverly designed drugs. But the researchers caution that their study is a long way from the outmoded dream of a silver bullet that would knock out breast cancer – or any other kind. The report was published in the journal Nature.
September 21, 2012 The National Institutes of Health will retire over 100 chimps from biomedical research experiments after deciding there's no longer a need for them. Some chimps are headed to a sanctuary, while others will go to a facility in Texas that will care for them.
September 20, 2012 Different lineages of cat with the same coloration got their looks in unique ways. The genetic variants that determine those patterns come from different mutations in the same genes. And that has some scientists thinking there may be more to the genes than meets the eye.
