3 … 2 … 1 … Blast Off!

NIH has awarded some grants for biomedical research at the International Space Station, reports Technology Review's Brittany Sauser on the Delta-V blog. NIH and NASA are teaming up to learn more about health issues in microgravity. The research will include experiments on the effects of bacteria and other microorganisms that have been shown to become more virulent in space, and the effects of prolonged space travel on astronauts' bones, Sauser says. The experiments will begin here on Earth, and then researchers will prepare them for launch and work with astronauts to continue them on the space station.
