Stripping down science, the naked scientists.

Hello, welcome to this week's naked scientists with me, Dr Chris Smith, and with Dave Ansel.

This week we'll be hearing how earthquake science can be used to diagnose broken bones in both athletes and even race horses,

finding out how to build lasers on microchips to make them go even faster,

and uncovering the cause of out-of-body experiences.

And also tonight we'll be exploring the science of catalysts including how your car's

catalytic converter works and also how catalysts can help to solve the Earth's

looming energy and pollution crises.

Emma Schofield and Fraser Armstrong will be joining us to explain how that works.

In this week's kitchen science, Dave will be doing the experiment live here in the studio and he'll be using

Emma and Fraser as the guinea pigs if you want to take part all you're going to

need is yourself and a slice of bread. If you fancy winning yourself a lemon-powered

clock or even a copy of Dr. Chris's new book, Naked Science,

keep listening to find out how.

Computer chips are so I don't get a problem because they're getting faster and faster and

faster and it's hard to get information from one side of the chip to the other.

So what people want to do is use light rather than electrical communications to move the

information around. But the problem is silicon can't actually make it, you can't make a

laser out of silicon because if you when you try

and do it instead of getting light out you get heat out and you can do it with other

semiconductors like gallium acid and indium phosphide but the problem is that you
