Boldly going where no science show has gone before.

The Naked Scientists.

Hello, welcome to this week's naked scientists with Helen Scales.

Hello!

Coveday Vansel.

Hi there, and I'm Chris Smith.

Now coming up this week, why the Boxing Day tsunami wasn't the first of its kind because now

researchers think that it's happened at least three times before. When and how we'll

be finding out also how scientists are making molecular music with nanotubes. The

result are speakers that are very, very loud, but they're

virtually invisible. And also how elephants have learned to avoid roads, to avoid poachers.

Unfortunately, there's a knock-on problem and we'll be finding out what that is in just a second.

Helen.

Thanks, Chris.

This week, it's also our science question and answer show, so we'll be tackling your science questions,

including discovering whether cracking your knuckles causes arthritis, why there's no cure for

the common cold and we've all heard about absolute zero the lowest temperature

possible but is there a maximum or hottest temperature possible?

All intriguing stuff and that's on the way.

Plus we'll be hearing how an engineering group in Cambridge

are grappling with this particularly flighty question.

It's very hard when an aircraft flies over the wind farm to tell which ones an aircraft and which
