Boldly going where no science show has gone before.

The Naked Scientists.

Hello and welcome to this week's naked scientists and that's with Helen Scales.

Hello Helen.

Hello!

With Dave Ansel, hi Dave.

Hi Dave. Hi Dave. Hi Dave.

Kitchen Science and Physics Guru.

And of course I'm Chris Smith.

Now this week how bugs splattered on car

windscreens are helping scientists to work out how many species there are on Earth.

Also how a big step forward has happened in the light sensing technology arena, and that could help scientists to produce cameras that are not much thicker than a single piece of paper.

And finally, is a virus responsible for chronic fatigue syndrome?

Scientists in the US have come up with some tantalizing evidence

and will reveal what it is to you very shortly, Helen.

Thanks, Chris.

This week, it's also our science question and answer show, so we'll be tackling all your science questions, including finding out why water expands when it freezes, how cold-blooded species survive at very low temperatures and can an astronaut push

himself through space by shining a laser or a torch at something?

The answers to all those and many more are on their way.

Dave.

Thanks Helen and for kitchen science this week I'll show you a neat feet to explain the effects of pressure.

If you want to have a go grab a biro, a potato,
