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

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

Hello.

And also with me, Chris Smith.

Now coming up, a stroke of luck for doctors who are battling brain hemorrhages

because researchers have turned an 80% death rate into an 80% survival rate.

And we'll be finding out why shortly.

Also, we'll be hearing about frogs in China that croak with ultrasonic croaks so that their mating calls don't get

drowned out by the sounds of nearby running water. More on that in a second.

And also the robot that can give you a speedy hair transplant if the comb over

is beginning to look a bit unconvincing that's all on the way

Helen. Thanks Chris also this week we're looking into the menagerie of microbes that live on us and

inside us it might surprise you to know that we are quite literally passengers in our own bodies

because there are at least 50 times more bacteria living on us than there are human cells that we are made of.

But what do these bacteria do?

And is there any truth to the claim that living clean can give us those allergies that we suffer from?

We'll also be finding out whether the probiotic yogurt so you can see the supermarket actually make a difference to your health. Thank you very much Helen

and along the same lines you've heard that coughs and sneezes spread diseases but you

might want to hold your nose for this week's kitchen science. What I've done is

is taking some concier-ar plates that are very good at culturing

fecal bacteria and done some very crude experiments where we've exposed the plates to people

farting in terms of a naked fart with no pants and no
