When scientists in Texas reported in January that they had successfully used antiretroviral drugs (ARVs) to prevent HIV transmission in lab mice, colleagues received the news with great enthusiasm - and no small amount of concern. Positive study results like these offer hope that ARVs may someday help stem the rate of new infections worldwide, but public-health experts in the U.S. worry that they may also prompt people in affluent at-risk communities to leapfrog the emerging science and self-medicate. "It's inevitable," says Dr. Warner Greene, director of the Gladstone Institute of Virology and Immunology at the University...
...brain once considered language centers have been discovered in monkeys; instead of handling language, they control mouth movements. Geneticists in recent years have found human genes essential to language; it turns out that similar versions of the same genes make communication possible in other animals, from squeaking mice to shrieking bats...
Studies show that laboratory mice can smell too-similar MHC in the urine of other mice and will avoid mating with those individuals. In later work conducted at the University of Bern in Switzerland, human females were asked to smell T shirts worn by anonymous males and then pick which ones appealed to them. Time and again, they chose the ones worn by men with a safely different MHC. And if the smell of MHC isn't a deal maker or breaker, the taste is. Saliva also contains the compound, a fact that Haselton believes may partly explain the custom...

...road wasn't always easy, however. Folkman's first compound, which biotech companies rushed to test in people at the beginning of this decade, proved less effective in patients than in mice, giving skeptics yet another reason to doubt the approach. But that agent, dismissed by U.S. researchers, eventually won approval in 2005 for treating lung cancer in China, where it is extending the lives of non-small-cell lung cancer patients...
