Stripping down science, the naked scientists.

The Naked Scientists. Today, Sunday the 15th of April, marks 100 years since the sinking of the Titanic.

And in recognition of the centenary, this week we're diving into the underwater world to look at a new vehicle

being delivered by Rolls-Royce to rescue people trapped in sunken submarines.

In exercises we've demonstrated the ability to leave the surface, go to the disabled submarine

perhaps 80 to 100 meters below the surface and achieve a mate in less than 15 minutes.

We'll also find out what else is lurking in the depths with the help of a marine scientist who studies the deepest places on earth, up to seven miles down.

Hello, I'm Ben Valsler and also here this week is Sarah Kaster Perry.

Hello!

In the news this week, what are robots revealing about how we hear in noisy places and

how do homing pigeons find their way home?

So if you would like to get in touch with any questions or any comments?

100 years ago today, the cruise ship Titanic hit an iceberg and sank with a

tragic loss of life. So to start today's show we're going to look at some

technology that's designed to save lives out at sea.

Submarines, manned or unmanned, have been vital in learning about the deep sea, as well as playing an essential role as part of our armed forces.

But sometimes subs get into trouble.

And like the passengers of a surface vehicle, submariners don't have the option to simply bail out into lifeboats,

and this makes submarine accidents very dangerous.
