| | | 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.

"If what interests you are new and exciting ideas, it's science you should be turning to. And whether it's the Human Genome Project or the origins of the Universe, Leading Edge is the place to hear about them."

The Pain of Rejection
Psychologists Matthew Lieberman and Naomi Eisenberger at the University of California in Los Angeles have been investigating what happens in the brain when a person is socially rejected.
Their experiment involved putting people in a functional Magnetic Resonance Imaging brain scanner as they played a computer game with what they imaged were two other players. During the game, the other players stopped including them in the game. The researchers monitored what happened in the brains of the rejected.
Duchenne Muscular Dystrophy
Claudia Hammond reports on a new experimental treatment for the inherited muscle disease, Duchenne Muscular Dystrophy.
Attempts at gene therapy so far have failed with this condition, but researchers at the Hammersmith Hospital in London are encouraged by their results of a new approach to rectifying the genetic fault.
Whales with Decompression Sickness
Until this week the assumption has been that whales don’t suffer from decompression sickness despite the depths to which the creatures dive.
But this week Paul Jepson of the Institute of Zoology and colleagues in the Canary islands reported in the journal Nature their discovery of dead beaked whales and dolphins with this condition.
More Metal, More Planets
Seven years ago, astronomers first detected planets around stars other than the Sun. Now they know of more than 100 stars with planetary systems, and a pattern has emerged. The more metal content a star has, the more likely it is to have planets in orbit about it.
Debra Fischer of the University of California in Berkeley explains why this should be and how the discovery is helping to understand how planets form in the first place. | | |
