“Clusters of cells are being grown on tiny devices, or chips, that mimic human organs to make it easier to test new drugs. Sangeeta Bhatia at MIT has been perfecting liver on chips, Gordana Vunjak-Novakovic at Columbia has been doing the same with hearts, while Donald Ingber at Harvard has developed guts on chips and lungs. If and when these people work together (and they’ve already collaborated in the past) we’ll really be able to put together a human-on-a-chip!” - Nina Tandon
