Could researchers tap mobile phone record troves to help save lives? A debate is afoot, and Amy Maxmen exhaustively investigated the pros and cons.   How it works: Anonymized, aggregated records of the origin and timing of texts and calls provide population movement clues…

Women account for over half of people living with HIV worldwide. That’s not obvious from the research, which relies heavily on gay male participants. Yet there are key differences in how male and female immune systems respond to the virus—a relevant factor in efforts to…
