Three share Nobel chemistry prize

Three scientists have won the 2010 Nobel Prize in chemistry for developing a chemical method allowing researchers to make potential cancer drugs and other medicines as well as slimmed-down computer screens.

American Richard Heck, and Japanese Ei-ichi Negishi and Akira Suzuki were honoured for their development of one of the most sophisticated tools available to chemists today, called palladium-catalysed cross couplings.
