At last night’s pub night, conversations ranged from the magical mysteries of impact factors, to MIT’s new cancer building (groundbreaking expected next week), local scientists who are part of rock bands and, inevitably, the latest wacky science videos making the rounds on Youtube.

People were raving about a video from Biorad (the equipment supplier), which was so overflowing in cheese that I cringed. Who would have thought a PCR machine could illicit so much, er, emotion?
