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...

Food prices there, she notes, are already being driven up in part by demand for biofuels, which is leading to the substitution of food crops by those that can produce fuel.
