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 fight against obesity - do we crave calories rather than the actual taste of food? |
The brain's calorie counter
The current obesity epidemic has galvanised scientists into working out the biological ways in which we control our food intake. Geoff Watts examines new research into a so-called “calorie counting” area of the brain. Could this, rather than the taste of food, be the main reason why over the long term we get satisfaction from high calorie foods and why so may diets fail after just a few weeks?
The Able Prize for maths
Mathematician Marcus Du Sautoy reports from Oslo on the announcement of this year's winner of the mathematical equivalentof the Nobel prize.
Shark tagging
Tagging great white sharks is providing new insights into their elusive routes round the globe – knowledgethat could help tighten conservation regulations of one of the ocean’s most endangered animals.
Transplanting hearts
And a new approach to repairing hearts - Roger Laham at Harvard Medical School is pioneering a new technique; transplanting healthy heart tissue to the site ofthe attack in the same heart, which could transform long term outcomes for heart attack patients.
