Live from the BBC The Naked Scientists.

And a very good evening to you in radio land and podcast land out there. We are the naked scientists. It's me

Dr Catani and here with me is Dr Dave Ansel. Hi and we're going to be telling you

why gossip may actually be a good thing for you and how scientists want to use lasers to push satellites around.

If you've got any questions about the technology of music, how sounds are made, what sort of

of things sounds being used for, get calling in 08459, 25,000 and you can email us at Chris at the Naked Scientist.com.

So get calling in any questions to do with music, technology, and also general science and technology.

Get calling in 849, 25-2,000. And here we also have some news from

Dave. Well scientists, astronomers have always had a big problem. They want to be able to see

very, very small things a very long way away and see that you need a really big problem. They want to be able to see very, very small things, a very long way away.
