It's science, but not as you know it, the naked scientists.

Hello and welcome to this week's naked scientists with me Chris Smith and also with Cat Arnie. Hello cat.

Hello.

Now in the program this week we've got a new self-adhesive tissue glue that could make stitches and staples a thing of the past.

We'll also be hearing why the 150 year old theory of why there are circles on a moth's wings

is actually wrong, and atomic billiards.

Scientists have managed to measure the force that's needed to drag

individual atoms and molecules around on a surface and they're saying it could be a big

breakthrough when it comes to making the next generation of nanom machines that's all

on the way cat.

Thanks Chris also this week we're looking at new technology

that's making life fun easier and safer for all of us.

We'll be hearing about a new system being pioneered in Australia

to work at how old you are from just your photograph, find out how it

fared on the naked scientist team. We'll also be meeting the computer that can read and then

paint your emotions and we'll be delving into a new world inside the internet.

It's called Second Life and Dave Taylor and Gordon Clark will be here to tell us all about it.

Plus, when you got rid of your last computer, did you delete everything from the hard drive?

Or at least, did you think you deleted everything from the hard drive?

Because the chances are that all of your personal details are still lurking there.

And if you know how, you can probably get that data back.

And we'll be talking to a forensic software expert who's called Graham Henley to find out how.
