July 1, 2013 One of the great dinosaur puzzles, the dinosaur mystery, is why did they suddenly die off? Scientists have been debating this question for almost a hundred years and one of the most beautiful notions came from an insect scholar who thought maybe caterpillars did it. I'm not making this up.
June 29, 2013 At night, in the ocean, they look like little Broadway billboards with dazzling trills of rainbow colored light. They have eight little runways on their bodies for light display. What are they?
June 28, 2013 You find a hair on a table top. A cigarette butt on the street. You take it home, and using not especially sophisticated tools, you recover traces of DNA.
