Researchers have successfully tested two candidate vaccines that may eventually be used together to confer immunity against HIV infection. Their findings are published in the December 15 issue of The Journal of Infectious Diseases, now available online.

University of Cincinnati (UC) environmental health researchers have determined that firefighters are significantly more likely to develop four different types of cancer than workers in other fields.

Researchers at UC Irvine have found that how much detail one remembers of an event depends on whether a certain portion of the brain is activated to "package" the memory.

It's biology's version of the director's cut. In much the same way that numerous films could be stitched together from a single reel of raw footage, a molecular process called alternative splicing enables a single gene to produce multiple proteins. Now a new RNA map, created by a team of researchers at Rockefeller University and the Howard Hughes Medical Institute and announced in the journal Nature, shows for the first time how the specific location of short snippets of RNA affects the way that alternative splicing is controlled in the brain.

Margaret River in WA, famed for its wine, is about to become famous for another reason: warning coastal dwellers what they may have to cope with under global warming.

Nitrogen gas is converted to ammonia fertilizer by a chemical process that involves high temperature and high pressure. Nature does the same thing at ambient temperature and pressure. The process, called nitrogen fixation, is essential to life as it provides nutrients to plant life.
