Summary

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. Recommended Reading Bird Flu Is Infecting Pet Cats.

0:49.4	We'll start about three billion years ago when scientists say a giant space rock may have helped
0:55.2	jumpstart life as we know it. In a study published last Monday in the proceedings of the National
1:00.4	Academy of Sciences, researchers describe a meteorite called S2 as being four times the size of
1:07.0	Mount Everest. That makes it as much as 200 times more massive than the rock we associate
1:12.5	with the death of the dinosaurs. When S2 crashed into our planet about 3.26 billion years ago,
1:19.5	the study authors say, life was just getting started. So only single-celled organisms were around
1:25.5	to experience the chaos wrought by the 36-mile-wide
1:29.5	meteorite. The researchers say that that likely included a tsunami, some boiling oceans,
1:36.1	and skies darkened with thick dust across the globe. So yeah, pretty spooky stuff. But in studying
