Bill Gates Will Give You $100,000 to Build a Better Condom

Condoms are recognized and used by an estimated 750 million people across the world and reduce both unwanted pregnancy and the spread of sexually-transmitted infections. However, unlike most other technologies, they haven't changed much in the last half-century. So isn't it about time for something new?

Yes, says the Bill & Melinda Gates Foundation, which is offering $100,000 of initial funding with up to $1 million of possible continued funding to whoever designs the "next generation of condoms." What might such a futuristic prophylactic look like?

"The primary drawback from the male perspective is that condoms decrease pleasure as compared to no condom," says the Foundation's description of the challenge.
