Taking a Flier
So the rumor below turns out to be at least 50% right...
the Crimson reports that the medical school has a new dean—
Jeffrey F. Flier, an expert on obesity and diabetes. (See photo below.)

His appointment came after a nine-month search that seemed to be nearing an end in late May, when Elizabeth G. Nabel, director of the National Heart, Lung, and Blood Institute and reportedly a top candidate for the Medical School deanship, traveled to Cambridge for a series of search-related meetings. But several weeks after Nabel's under-the-radar visit, Faust named Barbara J. McNeil, a professor of health care policy, to lead the school on a temporary basis while Faust rushed to find a permanent leader.
Hmmm. Kinda sounds like the second part of the rumor below is also correct....
The Crimson's piece seems quickly done; it's largely drawn from press releases. Meantime, here's
an interview with Dr. Flier, and here's a paper by Dr. Flier suggesting that
if we sleep more, we eat less.
