The Bill & Melinda Gates Foundation Wednesday will announce more than $10 million in grants for cutting-edge global research projects.
Scientists from the United States and around the world will get $100,000 to see if their highly speculative ideas have potential to save lives in the future.
The projects range from unmanned drones to deliver vaccines to remote areas to using temporary tattoos to monitor pregnant women in remote areas.
The foundation says another six ideas have passed the initial stage and will be given $1 million each to advance their projects.
Over the past four years, the Gates Foundation has funded more than 600 projects from more than 20,000 proposals submitted by researchers in 44 countries.
