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.

The marshlands of Southern Iraq

This week on Leading Edge -  restoring the marshlands of Southern Iraq, preparing for the next tsunami and self-healing aeroplanes.

Preparing for the next tsunami


Scientists analysing the aftermath of the Boxing Day tsunami warn that the event may now trigger another large earthquake and perhaps another tsunami.

This makes the need for an early warning system all the more urgent. Will it be in place in time to minimise another catastrophe?

Exploring the magnetic North Pole

From the edge of the Arctic ice sheet, we hear from the amateur explorers from England and Ireland who are embarking on foot to the Magnetic North Pole.

Along the way, they'll be making scientific measurements for the European Space Agency and the Geographical Survey of Canada.

Restoring the Garden of Eden

The vast marshlands of Southern Iraq - thought to be the site of the Garden of Eden - suffered enormous environmental damage after they were drained during Saddam Hussein's rule.

Azzam Alwash of the Iraq Foundation's 'Eden Again' project reveals the results of a post-war project to restore the marshes to their former glory. 
 
Self-healing aeroplanes

Cracks in aeroplane wings, caused by hail storms and other events, often get worse during long-haul flights.
But researchers at the University of Bristol may have a solution. A material made from hollow fibres that 'bleeds' resin when damaged, could be used to 'heal' these newly-formed cracks.
