Scurvy, Bird Flu and a Big Old Meteorite

Scientific American
About this episode

An enormous meteorite’s impact 3.26 billion years ago may have made conditions on Earth more hospitable for life in the long run. Washington State is the sixth state to report cases of bird flu in humans. Weight-loss procedures and treatments could lead to an uptick in scurvy cases if patients and physicians aren’t vigilant about vitamin C. And scientists are learning more from the remains of a Norse soldier whose body was dumped in a well some 800 years ago.
