PROGRAMME INFO
Thursday 21:00-21:30
Leading Edge brings you the latest news from the world of science. Geoff Watts celebrates discoveries as soon as they're being talked about - on the internet, in coffee rooms and bars; often before they're published in journals. And he gets to grips with not just the science, but with the controversies and conversation that surround it.

Geoff Watts looks at the top science stories of the week, with science writer Gabrielle Walker.

Corals in danger

Leading coral reef scientists meet this week in Florida to discuss the state of the world's corals, now sadly under serious threat thanks to climate change and human disturbance.

Geoff talks to Professor Peter Mumby of Exeter University, one of the key players at this international meeting, about the extent to which climate change is threatening these valuable ecosystems, and what, if anything, can be done.

Avian Flu

Geoff talks to Professor Mark Walport, Director of the Wellcome Trust, about the dangers still posed to humans by avian influenza, and the need to stockpile a vaccine.

Birdman of Bognor

Tracey Logan reports from this year's Birdman of Bognor competition, as the nation's most intrepid aviators attempt to take to the air in human-powered flying machines.

It may seem eccentric, but the science of low-powered flight is not well understood, and competitions like this could shed light on solar-powered crafts of the future.

International Year of the Potato

Britain's favourite vegetable is being honoured this year.

Geoff visits the Natural History Musuem's herbarium to talk to botanist Sandy Knapp about how the latest genetic techniques have helped uncover the history of the potato and its journey from the wilds of ancient Peru, to our modern-day chip pans.
