The Hello, Hello and in the show this week power at your fingertips scientists have invented a new

material that can generate electricity from the heat in your digits. Also what

the Large Hadron Collider is about to start looking for next and how new types of LED

are making it possible to transmit data through ambient lighting.

If you are sitting at an aircraft with a light above you, If you're in a meeting room with lights above

the meeting table, then those lights are a means of communicating information,

a potential supplement or replacement to Wi-Fi.

All illuminating stuff.

Plus this week we're analyzing asteroids.

We'll find out where asteroids come from, and is one about to collide with the Earth.

We're also meeting the asteroid miners.

There are companies out there looking to go prospecting in outer space,

but how do you mine an asteroid?

If you would like to get in touch with us here at the naked scientists, email Chris at the

naked scientist.com, tweet at naked scientists or find us on Facebook.

The naked scientist podcast is powered by UKfast.co. Now first up joining Dominic and me to take a look at the science news this week is

science journalist Mark Peplo. Lori Winkless, who's a scientist at the National Physical Laboratory and also BBC broadcaster Victoria Gill.

So let's kick off with you, Laurie.

A Thermoelectrics at your fingertips. Tell us more.

Yes, it's a really interesting paper that's just been published.

It's a group of Korean researchers who've produced a flexible thin film thermoelectric device

that can generate electricity simply from the heat produced by your fingertips.
