This week on Science Weekly I met leading conservationist Professor Kate Jones, joint chair of ecology and biodiversity at University College London and the Zoological Society of London. We discussed a recent TEDx conference in Washington on how genetic science could bring back extinct species.
The TEDxDeXtinction conference gathered leading scientists and experts, from geneticists and conservationists to ethicists and Hollywood producers, to debate the dawn of the new era of de-extinction.
Later, I was joined Observer science editor Robin McKie, who described a breakthrough in the creation of synthetic vaccines by UK scientists.
Finally, Guardian science correspondent Ian Sample met Anthony Challinor, Steven Gratton and Mark Ashdown, three of the Cambridge-based scientists behind the release of a map of the oldest light in the universe.
