..., the protein line could split, diverging into two distinct genes. This multi-tasking may also partly explain another phenomenon that has been puzzling biologists: rapidly emerging drug and antibiotic resistance, and enzymes that have adapted to break down man-made chemicals that have only been around for 50 ...Shedding feathers early may enhance sex appeal, new songbird study shows
... Birds that migrate early in the season may have a distinct advantage when it comes to attracting the opposite sex, say researchers from Queen's University and the Smithsonian Institution. And it's all about the feathers. Researchers were surprised to discover that the timing of a male songbird's reproduction...Vollum Institute discovery may unlock human genome

One study in the project, for example, found that Abert's Towhee, a mid-sized bird that is relatively uncommon in the desert, thrives in Phoenix because the city is crisscrossed with canals, which mimic the riverban...JCI table of contents, 3 January 2005

The authors show that a distinct viral species is activated by IL-7, and suggest that different molecules may deplete only a specific proportion of the latent HIV-1 population in individuals on HAART.
