"Barking up the wrong tree" has a fun list of a bunch of cliches and sayings with links to research on whether or not they could be true, so click here if you want to know whether or not nice guys finish last, if you can tell a lot about a man from his handshake, and if blondes have more fun.
Over at EurekAlert is a blurb about a Banaca-like oral spray that could help cut down on your susceptibility to airborne flu virus... the secret ingredient (cetylpyridinium chloride) is also a main ingredient in some non-burning mouthwashes, so using the right mouthwash frequently might also help to cut down on your flu susceptibility (though that has yet to be tested).
Apparently the guys over at Freakonomics are also fans of the band Bullets for My Valentine becaue they posted this podcast about guns in America just this past Valentine's Day.

I believe some of the credit for the discovery should go to early 90's rockers King Missile who first postulated the possibility of such a phenomenon in their song "Detachable Penis"
