Sabre-tooth Teeth and Centenarian Genes - Naked Scientists NewsFLASH - 05.07.10 - a podcast by Dr Chris Smith

In this NewsFlash, we hear about the melanoma stem cells that fuel the growth of tumours, the genes that could mean you'll live to be 100 and the fossils that show the earliest multi-cellular organism. We'll hear the evidence that Sabre-toothed tigers packed a mighty punch, as well as a big bite, and how a new x-ray laser has created"cored"atoms.
