Summary

This week, we delve inside atoms to find out what matter is made of, and how smashing them together can tell us about the birth of the universe. We learn about quarks, antimatter and the 'god particle' and discover that scientists are actually trying to build a black hole in the lab! Also, nano-wires give us the world's smallest solar cells, we hear about glue from mussels that sticks to teflon and the genes that tell you when to wee. Plus Meera peers inside the Dead Sea scrolls without even having to unroll them, using x-rays called 'synchrotron light', and Ben and Dave show you how to... Like this podcast?

Stripping down science, the naked scientists.

0:06.0

Hello, welcome to this week's edition of the naked scientist

0:09.0

from me, Chris Smith and also with Kat Arnie.

0:11.0

Hello, cat.

0:12.0

Now coming up this week, we've heard of solar cells,

0:14.6

but now scientists have made the world's smallest examples of them.

0:17.3

They're solar-powered nanowires.

0:19.1

They're absolutely tiny.

0:20.1

They're just 200 times thinner than a human hair.

0:23.0

So absolutely microscopic, how do they work?

0:24.9

Well, we'll be finding out surely.

0:26.4

Also, we'll be hearing how researchers have used a chemical,

0:30.1

which is normally found in the brain

0:31.6

to produce a glue that's so sticky that it'll even

0:34.1

bind to Teflon, so what can we do with it, and also how scientists have discovered how the human

0:38.9

body combats viruses and in particular hepatitis C. That's all on the way.

0:43.0

Also this week we are delving into particle physics

0:46.0

including paying a visit to the diamond synchrotron in Oxford.

0:49.0

That's the most expensive diamond I think we'll ever get near to.

0:52.0

And this is helping scientists to solve the mystery of the dead sea scrolls

0:55.7

Those ancient parchments that go back thousands of years, but actually too delicate to even unroll

1:00.9

We can take lots and lots of pictures at different angles of a piece of parchment
