Cell receptor work wins Nobel prize for chemistry

Two American scientists won the 2012 Nobel Prize for chemistry for groundbreaking work on a key family of receptors which enable cells to sense their environment, the prize committee said on Wednesday.

The Royal Swedish Academy of Sciences said in a statement the 8 million crown ($1.2 million) prize went to Robert Lefkowitz and Brian Kobilka for discovering the inner workings of G-protein-coupled receptors. (Reuters)
