On a blustery day in mid-December, TWiV co-host Vincent Racaniello and I, along with friend-of-the-show Islam Hussein, visited the picturesque campus of the Tufts University School of Veterinary Medicine in Grafton, MA. Our primary job there was to record an episode of TWiV in front of a live audience, featuring Tufts researcher Jon Runstadler and members of his lab. You can check out that episode now on the TWiV site. Before the recording session, though, we got to tour New England’s only veterinary school, which occupies the former site of a state mental hospital.

For a modern reader, the most surprising thing about the Galàpagos Islands chapter in Charles Darwin’s Voyage of the Beagle is probably its brevity. Darwin describes the apparently recent volcanic origin of the place, runs through a quick list of its notable species, includes a figure of some finches’ beaks, and then departs for Tahiti. His entire visit to the islands lasted only five weeks, during a voyage of nearly five years.

Here’s something that doesn’t happen often: I disagree with my friend, podcast co-host, and former mentor Vincent Racaniello. He’s generally right about most things. But I have to part ways with his take on public health-related travel bans, which he explained in a recent post on his blog: Why is it important to stop travel out of the [Ebola virus] affected countries? While I’m confident that the US can detect and properly contain imported Ebola virus infections, not all countries will be able to do so.
