Press release from Nature and the Nature Research Journals dated 7 September
NATURE (http://www.nature.com/nature) [1] Uric acid signals danger DOI: 10.1038/nature01991 (http://dx.doi.org/10.1038/nature01991) Uric acid may signal the immune system to warn it of impending danger, according to a paper published online by Nature this week. The research provides a molecular link between cell injury and immunity, and may have... view more... (2003-09-08)
Evolution study tightens human-chimp connection
Scientists at the Georgia Institute of Technology have found genetic evidence that seems to support a controversial hypothesis that humans and chimpanzees may be more closely related to each other than chimps are to the other two species of great apes - gorillas and orangutans. view more (2006-01-24)

Old gastrointestinal drug slows aging, McGill researchers say
Recent animal studies have shown that clioquinol - an 80-year old drug once used to treat diarrhea and other gastrointestinal disorders - can reverse the progression of Alzheimer's, Parkinson's and Huntington's diseases. view more (2009-01-07)
Delayed neurological development contributes to night-time bedwetting in some children
Night-time bedwetting in some children is likely to be caused by delayed neurological development, finds research in the Archives of Disease in Childhood. This can be predicted by a drawing test, shows the research. Thirty four children aged between 7 years and 13 were studied. They all wet the bed at least four times a week. The children were... view more... (2002-08-20)
