T.S.B. proud partners of the Pride of Britain Awards. Stripping down science to the Naked Scientists. I'm Chris Smith.

This week we're taking on your science questions including finding out what happens if you

shine a laser beam through a magnifying glass do you get some kind of super laser as a result.

Plus we've got news that we're very unlikely to be alone in the universe.

A new study suggests that as many as one in four stars resembling our own sun is likely to have an Earth-sized planet orbiting it.

That's all on the way. Also joining us this week on the program, because it is National Pathology Week,

is Pathologist Dr. Susie Lishman. Hello Susie.

Good evening, Chris. She'll be answering your pathology questions and also with us this

week is our kitchen science king. That's Dave Anseuhardi.

Hello and this week I've got a great trick for you to try at home, which will maybe you see the information

which is actually stored on your credit card.

I'll explain how you can do it later in the program.

Might come in handy if you've got someone who's a bit of a spender freak on your credit card.

Maybe not, I don't know, but I'm intrigued all the same, thank you Dave.

If you've got any science questions, we would love to hear from you.
