Summary

We explore the explosive science of volcanoes this week! We find out what you can learn from drilling into a restless volcano, how gravity is used to "weigh" volcanoes and watch them fill with magma, and we explore the theories behind volcano formation. Plus, we hear about the genes that could mean you'll live to be 100, fossil evidence of the earliest multi-cellular organism and the signs that Sabre-toothed tigers packed a mighty punch, as well as a big bite. In Kitchen Science, we get messy with a cola and wallpaper paste eruption! Like this podcast? Please help us by supporting the Naked Scientists

The Naked Scientists Hello coming up this week a new breakthrough in melanoma scientists have found

the stem cell that could cause the cancer to spread.

0:25.0

Also how a genetic test could soon be on the cards to tell you if you'll live long enough to receive a telegram from the Queen.

And what one of the world's most powerful lasers is now revealing to scientists about

0:36.4

the inner workings of atoms.

0:39.1

That's all on the way.

0:40.1

Hello, I'm Chris Smith.

0:41.1

Welcome to this week's naked scientists and also here to help me with the show.

0:44.3

Here's Catani Helicap.

Hello!

0:46.7

Also this week we're looking into the science of one of nature's most awesome displays of power,

0:51.9

the volcano. We'll be talking to one researcher who's

0:55.1

drilling into a recent eruption site, that doesn't sound terribly safe to me, to

1:00.0

understand the processes that power volcanoes, We'll also hear how gravity can be

1:04.2

used to effectively weigh a volcano to watch as it fills up with magma and in a

1:08.4

rather explosive kitchen science, Ben's been getting his hands dirty.

1:13.0

Now you seem very well prepared.

1:15.0

You've laid out lots of newspaper and you're wearing a poncho.

1:19.0

So obviously this could get quite messy.

1:21.0

Don't do this indoors.

1:24.4

And you can find out what Ben's been up to and let me tell you it involves making a
