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."

Geoff Watts looks at the top science stories of the week with Daily Telegraph science editor, Roger Highfield.
Spot the ball
Free kicks and corners in Euro 2008 may have been hampered by the new football designed for this year鈥檚 tournament.
Tiny pimples have been introduced across the ball鈥檚 surface. According to theoretical physicist Ken Bray, they have made its aerodynamics 鈥渢oo good鈥, causing headaches for goalkeepers and strikers alike.
What to do about whales
The growing threat to whale species is being discussed in Chile this week at the International Whaling Commission.
It鈥檚 not only hunting that鈥檚 causing their numbers to dwindle. Whales are caught in fishing nets, hit by ships and affected by climate change and over-fishing.
New diseases are also springing up, such as 鈥榮tinky whale鈥 syndrome.
大象传媒 Environment correspondent Richard Black reports from the meeting.
Antarctic sealife
Whales, penguins and seals are normally what you鈥檇 expect to find in the Antarctic.
But, as Gabrielle Walker found out, giant clams and ugly worms are far more abundant in the sea.
She ventures out with the British Antarctic Survey on a dive near Rothera Research Station.
Four-legged fish
How did fish evolve to survive on land?
A paper published in the journal Nature this week describes a new creature, Ventastega (pictured above) which may help plug an evolutionary gap in our knowledge.
The size and shape of an alligator, it had a fish-like tail and four legs each containing around nine toes.
Geoff Watts talks to Swedish palaeontologist Per Ahlberg who discovered this fishy beast.
ERNIE 鈥 the first computer celebrity
ERNIE, the 50 year old random number generator, has just gone on show at the Science Museum in London.
It produced numbers for the national Premium Bonds draw, launched by Harold Macmillan, then Chancellor of the Exchequer, in November 1956.
The first numbers were drawn the following June by ERNIE, a first generation 'computer' the size of a transit van.
Geoff meets one of the original engineers, Jack Armitage and museum curator Tilly Blythe, who has collected cards and poems sent to ERNIE by the British public.听
