Boldly going where no science show has gone before.

The Naked Scientists.

Hello, welcome to this week's naked scientists

with our all-star specialist in biology,

cancer and everything else, Kataani, hi Kat.

Hello!

And also our kitchen science guru and physicist extraordinary, Dave Anso.

Hi Dave, Dave Anso, hi Dave. Hi Dave. Hi Dave.

Good to have you with us. I'm Chris Smith.

And coming up this week, how scientists have developed a new and much safer way to test

unborn babies for genetic problems like Down syndrome,

and that's using surprisingly just a sample of the mother's blood.

Also after a lot of head scratching but when scientists have uncovered the genetic cause of male

pattern baldness and is this the stickiest substance known to man?

Scientists have copied the structure of the feet of a tiny lizard

to develop an incredibly powerful adhesive.

That's all on the way and it's coming up shortly, Kat.

Thanks, Chris. This week it is our science question and answer show.

We'll be tackling your science questions and

teasers including discovering whether lightning goes from the ground upwards or from the clouds

downwards. And we'll also be looking into the workings of one-way mirrors, intriguing for the perverts out there,

and finding out whether the Earth is getting heavier and where all the heat comes from to power
