100 EVAs, 100 Days to Earth
The crew working together on EVA 100. It's one hundred and seven days to mission's end. Sometimes, it seems like we're a few days from home instead of 15 weeks. Most days, it feels like we just marked the first 100 days on sMars. I can see us all sitting around the couch downstairs wearing scarves, balancing our musical instruments while arranging radios and rock samples to spell out "100". Then, just like that, it's day 258 and we're coming up on the 4th quarter. The better part of a year -..>> view originalAncient tools and bone found in Florida could help rewrite the story of the first Americans
The researchers say the find is unequivocal proof that people were in Florida more than 1,000 years earlier than anyone had imagined. (FloridaState/YouTube) Thousands of years ago, some of the first Americans knelt beside a pond in what is now Florida. Clutching sharp stone knives, they hacked at the tusk of a slain mastodon, slicing meat away from the long bone. Then, with their work completed, they got up and walked away, leaving behind some tools and the stripped carcass .

It's a little known but often dangerous problem: each year, 3,500 people in the U.S. -- mostly young children -- swallow button batteries. Normally, these batteries pass through the body without incident. But if they come into prolonged contact with esophagus or stomach tissue, the results can be harmful: the batteries can cause an electric current that produces hydroxide, which burns through body tissue.A postdoctoral student at the Massachusetts Institute of Technology, Shuhei Miyashita broug..>> view originalCritics attack Harvard's secret meeting on human genome synthesis
