Stripping down science, the naked scientists.

In this week's show, well you've heard of Sat Nav, but now meet Bat Nav because scientists

have discovered that bats can find their way around using the Earth's magnetic field and you can also send them off course with the help of a magnet and we'll be finding out how.

Also there's new information about the deadly Ebola virus in Africa, more on that shortly, and also scientists

have licked the problem of where to put an extraordinarily long tongue will be introducing

you to the animal that stores its tongue next to its heart.

Hi there, I'm Chris Smith.

Welcome to this week's Naked Scientists,

and also here to help me out, is Helen Scales.

Hi Chris.

Yep, also this week we're exploring the science of the Big Bang

and the birth of the universe with Cambridge

universities Jerry Gilmore will be flying across the service of Mars with

Peter Mueller from the University College London and also finding out how the

Sun can upset communications here on earth with

Giulio delzana. And if you have any questions on any of those things or any

general science questions for us, grab a pen and paper. We'll be giving you details

of how to get in touch with us very shortly.

And we've also got a very space-themed kitchen science for you this week because we'll be recreating

a meteorite impact. What you'll need to do if you want to have a go at doing this at home is a

tray, some flour and some cocoa and you'll also need some Malteseers or something round to

chuck at it. Yes, try not to eat those Maltesees till we tell you what to do with them.
