A molecular machine’s secret weapon exposed

RNAs can wreak havoc on cells if they aren’t removed at the right time. Dis3L2 is a molecular ‘machine’ that untangles and chews up RNAs, but scientists have been unable to explain how. Biochemists have now pieced together the answer. By shape-shifting…

Leptin helps hungry mice choose sex over food

To eat or to mate — that is the question (and the answer is: moderately hungry mice choose to mate). Researchers show that hungry mice prioritize interacting with members of the opposite sex over eating and drinking when their brains are stimulated wi…

Forecasting malaria outbreaks

A new study integrates climate, land use, and socioeconomic data to explain and predict malaria dynamics at the village level. The approach could inform health care practitioners and make control strategies more efficient and cost-effective.
