If you've ever had doubts about the power of advertising, take a look at a recent study appearing in the Journal of American Medical Association.1 Richard Kravitz, from the University of California, Davis, and colleagues found that when "standardized patient" actors portraying depression visited doctors and asked for Paxil, 27% of them walked out with a prescription for the drug, compared to just 3% of patients who described the same symptoms but did not ask for Paxil. That finding should be con

while it is true that a number of patents are involved in the technology necessary for the creation of Golden Rice, there is a general public perception that intellectual property (IP) issues have been a main reason for the delay in the introduction of Golden Rice to countries that badly need this technology.

please, spare us the sociological/political nonsense.

Tringe et al., "Comparative metagenomics of microbial communities," Science, 308:554–7, April 22, 2005.This important paper provides the first comparative analysis of both phylogenetic and functional diversity of entire microbial communities. The communities considered include those associated with farm soils, deep-sea whale carcasses, the S

In the estimated 5 million years since humans and chimpanzees began diverging, they've acquired major anatomical and cognitive differences.

© 2005 Center for Development BiologyResearchers at the University of Utah are among the first to use large-scale genetics to study the planarian Schmidtea mediterranea, which contains a genome thought to contain insight into adult stem cell pluripotency and tissue regeneration.1Because the organism does not reproduce sexually, it cannot be studied using traditional genetic techniques. But by using bacterial-fed RNA interference against 1065 planarian genes, the study "effectively makes an
