No sooner had I uplinked last week's episode, than related news showed up. This, a study doubting the asteroid theory of dinosaur extinction. Disappointingly, the study was presented non-critically by a number of media outlets (even popular "science" magazines). In particular, it was presented as "new" hypothesis, when it's really just the latest volley in a long-running exchange of scientific articles and press releases. I try to give everyone a little background on all this, and the underlying controversy that rarely gets much press.
