Boldly going where no science show has gone before.

The Naked Scientists.

On the Naked scientists this week, how the Asian monsoon season takes pollution to new heights,

why swine flu spared the elderly, how marine mollusks inspired new lightweight materials, and how the heart comes

by its coronary arteries, a discovery that could provide new ways to bypass clogged vessels. That's all coming up. I'm Ben

Valsler and this is Dave Ansel. We're also looking at the science of weather.

We'll find out how aeroplane contrails can create clouds, where insurance companies need the finest weather

forecasts and how you can steer a hurricane.

Also in kitchen science we'll be making our own rainbow and Diana has a question of the week that we can really get our teeth into.

Now my question is I've heard that a dog's mouth is cleaner than a humans.

And I'm wondering if that's true or is it that the normal flora of a human is more

virulent than a dog's.

So chew that question over, babum, and let us know if you know the answer. If you want to get in touch

about that or with any other questions or comments, we would love to hear from you. Send us an email to Chris at the naked scientists

dot com or you can tweet at naked scientists

This is a naked scientist with me Dave Ansel. And with me Ben Valsler and I will start off this week with a paper published in the journal Science that shows that pollution in Asia get pushed up into the stratosphere by hitching a ride on the monsoon.

William Randall at the National Center for Atmospheric Research in Colorado,

and an international team including researchers at York and Edinburgh Universities

used satellite imaging to keep track of something called hydrogen cyanide.

This is a pollutant associated with burning that usually stays mainly up in the troposphere,
