science news: hearts, longevity, tectonics, sleep, race
We can now grow a new heart using a real heart's collagen as a scaffold for new cells, and even get it beating. So far, rat hearts, and only a weak beat, but wow.
Resveratrol, a derivative of red wine, has been found to extend lifespan in humans.
Nasal hormone spray eliminates effects of sleep deprivation in monkeys.
A molecular biologist uses a combination of markers to accurately identify race from DNA. More accurately than eyewitnesses, apparently.
A livable climate apparently depends on plate tectonics, which in turn requires other conditions, and can change.
Thanks to Meowse for the links. Also heard about the hearts on NPR yesterday.
