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.

On this week鈥檚 programme - studying the brains of paedophiles, using ultrasound in the operating theatre, results from the Venus Express spacecraft and why meditation makes you happier.
Venus Express results
In November 2005, Venus Express was launched to investigate Earth鈥檚 evil twin.
A clutch of papers in this week鈥檚 Nature magazine looks at early results from the spacecraft鈥檚 data.
From temperatures that would melt lead, to upside-down lightning, Geoff peers into the Venusian atmosphere to see what鈥檚 going on.
Inside the mind of paedophiles
Could paedophilia be down to faulty wiring in the brain?
And if so, where does this leave us in terms of responsibility and punishment for the perpetrator?
Geoff Watts talks to Dr James Cantor from the Centre for Addiction and Mental Health in Toronto.
Ultrasound and bloodless surgery
Reporter Jon Stewart looks at a new medical device being tested in Seattle which cauterises internal wounds using ultrasound.
Meditation and the brain
Matthieu Ricard is a Buddhist monk from Tibet with a PhD in molecular biology.
He鈥檚 been working with Tania Singer, a neuroscientist from the University of Zurich, to find out whether meditation changes your brain activity.
Does the secret of happiness lie in controlling your brain waves?
