Stripping down science, the naked scientists.

Hello, welcome to this week's edition of The Naked Scientists with me, Chris Smith, and also

with Helen Scales.

Hi Helen.

Hello.

Now coming up this week how researchers have made the underwater equivalent of a

Post-it note and you'll have to find out why in just a second.

Also, can you listen to two things at once?

Because scientists have pinpointed a gene that lets some people do just that,

and if you can, perhaps you've got that gene.

And when it comes to exercise, why putting your feet up,

might actually, it turns out, be quite good for you. Plus how deep can you

go? Well we'll be taking a look this week at the science of free diving where people

descend to extreme depths on just one breath of air.

There's an Austrian guy called Herbert Meish and he's just gone down to

211 metres on a awaited sled.

And also this week we'll be looking at how the human body can handle some other extremes

including finding out how we cope with altitude at the top of Mount Everest, how fighter

pilots are trained to cope with those G forces inflicted on them by

high-powered jets and how life survives in the deep freeze at the polar ice caps.

And also there's this week's question of the week where we're going to be taking a look at this rather

intriguing conundrum.
