The journal Science has lauded an eye-opening HIV study, known as HPTN 052, as the most important scientific breakthrough of 2011. This clinical trial demonstrated that people infected with HIV are 96% less likely to transmit the virus to their partners if they take antiretroviral drugs (ARVs).

People at high risk for malaria may benefit from swallowing a cocktail of antibiotics as a preventative measure, a new Science Translational Medicine study in mice suggests. The drugs may evoke natural immunity to malaria parasites in healthy but vulnerable populations, providing lifelong protection against future malaria infections.
