An article posted last hour on washingtonpost.com by Joel Achenbach examines an upcoming paper in Science that explores the idea of an impact triggering the Younger Dryas glacial advance as well as ending the Clovis culture and triggering the extinction of the Pleistocene megafauna. The evidence is nanodiamonds in sedimentary deposits from 12,900 years ago. Read the article, and wonder how Joel Achenbach finds out about this stuff a day before it's published. How does he get his hands on this article with enough time to compose a newspaper piece about it, but the rest of us have to wait until tomorrow to read the original paper?
