Pioneering research into a "gay bomb" that makes enemy troops "sexually irresistible" to each other has scooped one of this year's Ig Nobel Prizes.
Other winners included work on treating hamster jetlag with impotency drugs, extracting vanilla from cow dung, and the side-effects of sword swallowing.
The awards, founded in 1991, mark achievements that "first make people laugh, and then make them think".
The prize ceremony took place at Harvard University, US.
Genuine Nobel Laureates handed out the much-coveted awards to the winners, who took away no cash, but instead received a handmade prize, a certificate, and, of course, the glory of such an illustrious win.
