Earlier this week, the Bill & Melinda Gates Foundation announced the latest 100 winners of $100,000 grants from its Grand Challenges Exploration program aimed at supporting high-risk, creative approaches to improving health and fighting poverty in poor countries.
Celebrated for funding “wild” and “wacky” ideas, this year’s batch of Gates Grand Challenge winners included proposals to develop, as the AP reported, unmanned drones to deliver vaccines, tattoos for monitoring pregnancy and a “tuberculosis breathalyzer.”
