Bogus Trivia

One of these stories is bogus. Have you been paying enough attention to science news to know which one? (Full disclosure: I picked it out easily; the reason it's bogus is kind of funny in itself.)

Story 1, a study of the views of men who were regular consumers of pornography found that they did indeed have poorer eyesight on average than nonconsumers.

Story 2, photos from the Tiger Woods crash scene revealed a physics book in the back seat of the vehicle.

Story 3, a specific type of anxiety has been linked to the likelihood of becoming depressed—and that anxiety is anxiety about having anxiety.

And story 4, the genome of corn has been sequenced and published.
