PROGRAMME INFO
Thursday 21:00-21:30
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.

Floating pieces of iceberg

This week on Leading Edge - climate change, galaxy maps, Harry Potter and the Tour de France.

Global Climate Change Debate

Is Global Warming a real phenomenon?

Absolutely, according to the vast majority of the scientific community, but it seems some members of the US congress are having trouble accepting what is now widely believed to be science fact.

Geoff Watts talks to Richard Harris, science correspondent at National Public Radio in Washington DC, about a dispute between politics and science that is currently brewing on Capitol Hill.

Mapping the Universe

Geoff talks to Dr David Weinberg of Ohio State University, about two extraordinary projects that are literally mapping the heavens.

These two new surveys are plotting the three-dimensional spread of galaxies over an unimaginable scale, and in the process shedding light on some of the great mysteries of our universe.

The Science of Harry Potter

A trip to the local bookshop should yield a plethora of books on the science that can be found in some very famous books.

The science of Harry Potter, Middle Earth and the Hitchhikers Guide all claim to have found nuggets of science fact in works that at first glance look like pure fiction.

But the authors claim there is a serious side to these works, bringing science to a wider audience in a popular and entertaining way.

But is the "Science of..." genre spoiling the fantasy, or  putting the magic back into science?

Tour de France

Geoff talks to cyclist Rob Hayles and Engineer Dimitris Katsanis, designer of the British team's bike that was so successful at the last Olympics and Commonwealth games.

With the Tour de France nearing completion, Geoff talks to both guests about the role science plays in getting the winner over the finish line.

Just a 1000th of a second can mean the difference between a gold and silver medal, and so everything to the design of the bike to the aerodynamics of the peloton, all play an important role.
