Stripping down science, the naked scientists.

Hello, welcome to a special Christmas edition of the naked scientists and that's with

Katani.

Hello.

With Dave Ansel. With Helen Scani. Hello. With Hello.

With Helen Scales.

Hello.

And of course me, Chris Smith.

That's right.

We've got the whole team of us here for a special festive program in which we're going to be picking

out some of our favorite scientific discoveries that have happened this year, including a

revolutionary new space rocket design that's actually based on a table decoration very Christmasy.

That should help to protect astronauts and radiation out in space.

Also, a tissue from a Tyrannosaur, how scientists have actually

extracted the original dinosaur tissue from a fossil and the king of the swingers, how orangutans

have worked out the perfect way to get around but without wasting any energy.

That's all on the way, Helen.

Thanks Chris and continuing with the festive theme and we are all dreaming of a white Christmas,

but is it true that no two snowflakes are exactly the same.

If you would add up the number of possible ways of making a snowflake, you easily

find it far greater than the total number of atoms in the universe.

So we'll be hearing how snowflakes form later on in the program.
