Summary

This week, is sugar the enemy? Difficult as it is to digest, one person in every four in the UK is obese, and treating the condition as well as its knock-on effects, costs the health service 5.1 billion per year. Some say sugar is to blame, but is it the only guilty party? Plus, in the news, pigeons detecting cancer, half of museum specimens might be mislabelled, and how science journals are being hacked...

0:00.0	And the This week we're getting our teeth into the subject of sugar. Experts say it's
0:19.8	fueling an obesity epidemic. David Cameron won't back a sugar tax, but would one work anyway, and
0:26.0	is sugar really to blame?
0:28.0	Plus, in the news, pigeons that can detect cancer?
0:32.0	Why half of the specimens in museums and other
0:34.3	collections may be mislabeled and how science journals are getting hacked. I'm
0:39.2	Katai and I'm Chris Smith and we are the Naked Scientists.
0:43.0	The Naked Scientists podcast is powered by UKfast.co.uk.
0:48.0	UK.
0:50.0	So far scientists have logged more than 1,900 planets orbiting other stars outside our solar
1:00.1	system, but no one has yet spotted any that are still in the process of forming.
1:05.0	Until now that is, because researchers in the US have finally spotted just such a planet.
1:10.0	It's in orbit around a young, 2 year old star which is 450 light years away from Earth
1:16.0	quite similar to our own son and catch really called LKCA 15.
1:20.4	Planetary scientist David Rothery who wasn't involved in the study, explained the significance of this discovery to Connie Orback.
1:27.0	What's exciting is we're seeing a planetary system in the act of a formation. There are three planets orbiting
1:35.9	this star. The nearest one's about 10 times Earth's distance away from the
1:40.9	stars. That's twice, Jupiter's distance away from our Sun.
1:44.0	And the furthest one is about 20-25 astronomical units, so that's a little bit less than Neptune's
1:50.6	distance from our Sun. So three giant planets and the innermost one
1:56.8	has still got gas falling into it which is as being measured at this very high
2:01.6	temperature of 10,000 degrees, but it's losing
