Boldly going where no science show has gone before.

The Naked Scientists

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

Hello Helen. Hello.

Hello.

And hi Dave Ansel.

Hi there and I'm of course Chris Smith.

Now this week scientists have discovered the ultimate in

adoption a caterpillar that gets brought up by ants but why do they choose to help a

butterfly? Well we'll be finding out shortly. Also why sea level due to global warming, might be much worse than we first thought,

and that's because scientists had previously overlooked the possible impacts of gravity in the equation.

And also, we'll be hearing about a new way to diagnose arterial

disease but get this using urine and we'll be finding out how 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 the sound of

fingernails is so awful when they're dragged down a blackboard and sends shivers

down your spine why chewing a piece of metal foil makes your

fillings taste all funny and why is it that the sea is salty?

Dave. Thanks Alan and in a special on a sea kitchen site it's going to have a bit of

a race all you need is a microwave some ice

cubes and a bit of water and it's very easy to try at home so if you want to have a go

grab those along and I'll explain what to do shortly.
