What's the best way to explain the wonders of Planet Earth, the story of the human genome, or the mysteries of medicinal plants? How can scientists make origins of biped transportation, ethical issues relating to animal to human transplants, or programmed cell suicide understandable? What's the relevance of the birth of the Mediterranean, deep sea ecosystems, or the art and science of ice crystals? Excellence in answering such questions has led to 33 European projects being nominated for the Descartes Prize for Science Communication. From these 33 nominees, 5 finalists and 5 winners will be selected to share this year's €275,000 prize. The winners will be announced on 7 March 2007 at a ceremony in Brussels, together with winners of the Descartes Prize for Scientific excellence, on the occasion of the "Today is the Future" event, celebrating the launch of the 7th Framework Programme for Research and 50 years of European Research.
