New drugs for old bugs: We should all be worried by the growing number of antibiotic-resistant bacteria and we urgently need to develop new drugs, says Ada Yonath. She and Brian Kobilka won Nobel Prizes for using x-ray crystallography to understand cell structures that are vital targets for drug development. In this film, three researchers challenge the structural approach and propose alternative ways to find drugs; some cutting edge, such as computation, and some ancient, such as searching for chemicals deep in the rain forest. What is the best way forward? Or is a combination of techniques the most promising approach?
