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.

Passports for Plants?
When Sudden Oak Death started killing thousands of trees in California, strict import regulations were imposed on two of the most virulent carriers of the disease - rhodendrums and vibernums.
But as the global trade in plant material expands and new diseases emergeÌýshould all plants carry passports?
CarbonÌýConundrum in the TundraÌý
Surprising findings from a long term experiment to model the impact of global warming in the Arctic.
It was thought that warmer soils would be more nutrient-rich, stimulate plant growth and so lock up more carbon in the ecosystem.
But it seems the reverse is true: adding fertilizers to tundra regions results in a net loss of carbon.
Engineering the Human Heart
The latest attempts to engineer one of the most complicated parts of the human body: human heart valves.
Musical Emotion Courtesy of a Computer
Researchers can now alter the way a piece of music sounds as easily as pressing return on a computer.
