While wearing a brassiere over his mouth, Professor of Physics Wolfgang Ketterle, recipient of the Nobel Prize in Physics in 2001, gives two thumbs up to the winner of this year’s Ig Nobel Public Health Prize on Oct. 1. The winner, Dr. Elena N. Bodnar, created a bra that can be taken off and used as a “gas mask” in the event of an emergency. The Ig Nobel Prizes, held annually at Harvard University, are awarded to scientists for “achievements that first make people laugh, then think.”
