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.

A Cure for Blindness?
Scientists are a step closer to finding a cure for blindness with the announcement this week in the journal Nature of a successful transplantation of immature retinal cells in mice.
Mice who had lost their sight had their vision restored when light sensitive photoreceptor cells were replaced by the technique.
Geoff talks to the eye surgeon who believes this paves the way for treatment of conditions like age-related macular degeneration and retinitis pigmentosa in humans.
What Future Online Shopping and Chip and Pin?
Technology journalist Bill Thompson explains why the strange properties of quantum computers could one day crack the code behind the security that underpins CHIP and PIN and the entire basis of online shopping.
Sea Urchin Genome
This week scientists announced the sequencing of genome of the sea urchin.
Sea urchins and humans share a number of genes.
They play a key role in helping scientists to understand the complex sequence of events that underpins how an embryo develops into an adult and what genes are involved in fighting human diseases and infections.

Pandemic 'Flu
'Flu vaccines can’t be made until you have some idea of the characteristics of the virus you’re trying to protect against so what should we be doing while we wait?
Geoff Watts finds out that scientific knowledge of exactly how flu spreads hasn’t improved much since the pandemic of 1918.
Titan’s Haze
