Craig Venter: A voyage of DNA, genes and the sea

Genomics pioneer Craig Venter takes a break from his epic round-the-world expedition to talk about the millions of genes his team has discovered so far, in their quest to map the ocean's hidden biodiversity. (Quite a task, when you consider that there are tens of millions of microbes in a single drop of sea water.) He updates the TED audience on his discoveries, from the 2,000 photoreceptor genes found in the Sargasso Sea to the thrill of being under house arrest in French waters. After touching on the potential of environmental genomics to monitor the safety of air, water and offshore drilling, Venter ends with his vision for engineered species that can replace the petrochemical industry by creating clean energy.
