Carbon capture is substantial in secondary tropical forests
Secondary tropical forests consume substantial amounts of carbon, but are often neglected in climate change policy. Credit: Robin Chazdon et al.

George Church, a professor of genetics at Harvard Medical School and an organizer of the proposed project, said there had been a misunderstanding. The project was not aimed at creating people, just cells, and would not be restricted to human genomes, he said. Rather it would aim to improve the ability to synthesize DNA in general, which could be applied to various animals, plants and microbes.“They’re painting a picture which I don’t think represents the project,” Dr. Church said in an intervie..>> view originalDung Beetles Navigate Poop-Pile Getaways Using Celestial 'Snapshots'

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 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 . Centuries pas..>> view original
