Scientists debate meaning of 40-million-year-old primate fossils in Nature
...ng. Seiffert and colleagues conclude that the new finds are compatible with the widely accepted view that the lorises and bushbabies (as a group) diverged from lemurs 50 million to 53 million years ago, and that their last common ancestor lived in Afro-Arabia.

Statins are a group of compounds that have been used successfully to lower cholesterol and prevent myocardial infarction.

...lowering blood pressure. Now, a new research study finds that a diet moderately high in grape seed extract can blunt salt (sodium chloride)-sensitive hypertension to about the same extent as treatment with either plant estrogens or 17-estradiol. This suggests that mechanisms other than the estrogen recept...Hebrew University excavations strengthen dating of archaeological findings to David, Solomon

A new UC Davis analysis finds that adult sea otters in California in 1998-2001 died in unusually high numbers from newly recognized diseases and in geographic clusters -- all of which suggest that their coastal environment may be so substantially altered that the species could be...Pattern recognition method zeroes in on genes that regulate cell's genetic machinery
...The new approach described in Nature Genetics also finds clusters, but it is the first to incorporate data about known and putative regulatory genes and the first to simultaneously predict which gene or genes regulate each cluster. In response to internal or external signals, regulatory genes tell cluster...Anti-HIV drugs save vision, improve outlook for AIDS patients

The Johns Hopkins team reported in the April issue of Archives of Ophthalmology that AIDS patients who received HAART had a 75 ...Few microbiological differences in households using antibacterials
