I have you loud and clear.

Hello.

Hello.

Welcome.

H.

Science and that is the say physics, medicine, nature,

big time, brain, life, the universe.

Hello this week, life here on Earth uses DNA,

but why does it do that? And would aliens be made of the same stuff?

Plus in the news how your gut microbes are controlling your genes, a new way to fight phobias

and life on Mars. We get a sneak peek at where the first

human colonist will live on the red planet. I'm Georgia Mills. I'm Chris Smith and

this is The Naked Scientists. The Naked Scientists Podcast is powered by UKfast.co.uk. We don't usually start the show like this, but we're breaking with tradition to ask if you can help us.

The naked scientist has been going for over 15 years now and

during that time we've created more than 1,000 programs which have been downloaded

tens of millions of times by listeners just like you all over the world.

We want to make sure that the naked scientist programs can remain available for free, for everyone, forever.

To do that, we need to meet our running costs, rebuild a website that's groaning under the strain of 80,000 pages of content,

and bring you a brand new suite of programs for 2017.

Now our target is to raise 50,000 pounds or more in the run up to

Christmas and we're hoping that you can help us out. This week appropriately

enough it's giving Tuesday so we'd like to appeal to you if you enjoy the program
