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.

Tired

Jet lag - you step off a plane tired and blurry eyed with your body seemingly unable to function. 

Our bodies are struggling  to readjust to the new time zone.  But surprisingly, our eyes are working overtime to help us.

New molecule
Russell Foster is thrilled to have discovered a new light-detection system in our eyes. It works quite differently to the 'rods and cones' that were thought to be our only light-sensing cells.

Biological rhythms
Conditions like jet lag could benefit from this finding. Join Geoff Watts to find out how.

Also in the programme
• The Y chromosome and its unique method of survival
•  Molly Bentley discovers what medical cures lie beneath the ocean waves
•  A 3d moving X-ray which could help back pain sufferers

Next week
A new electric motor could revolutionise navies worldwide.
