Boldly going where no science show has gone before.

The Naked Scientists

Hello, welcome to this week's naked scientists with me, Chris Smith, and also with Helen Scales. Hello.

Now coming up, our scientists have stumbled upon a way to get much more oxygen around your body and that could be good for

mountaineers of course people with heart failure and possibly also some Olympic

cheats how that works in a second also how researchers have identified two new ways

to stop Alzheimer's disease and sing a song of

distance. Scientists have tracked the migrations of songbirds and they found that they

routinely fly over 300 miles a day which is much further than we first thought and certainly not bad going

for something that's not much bigger than your fist.

Helen.

Thanks Chris.

Also this week we're looking for love, at least the chemicals that control the processes of

sexual attraction, bonding and ultimately falling in love.

We'll be hearing how women broadcast subtle clues about their fertility, including making

their voices sound slightly different when they're most likely to

fall pregnant. We'll also find out why people who look more symmetrical are judged

to be more attractive and why it is that we've evolved to fall in love at all.

Thank you Helen and we'll also It is that we've evolved to fall in love at all.

Thank you Helen.

And we'll also be finding out whether there's such a thing as a divorce gene

because scientists are beginning to think that there might be.
