This is Generation 1, the climate podcast from University College London.

Bringing groundbreaking research from the front lines of climate science,

we tackle climate action in all its forms from policy and activism to AI and urban planning.

I am a tech optimist. I am optimistic that it will help us solve some of the challenges,

especially related to climate

change.

It's science, but not as you know it, the naked scientists.

Hello and welcome to this week's naked scientists with Chris Smith.

Hello.

Dave Ansel.

Hi there.

And I'm Dr. Kat Arnie.

And in this week's program, we have the robot equivalent of Spider-Man, a new invention

that could see robots running up walls using electricity to stick on. Also, we've discovered how

scientists have uncovered the basis of how good gut bugs could make us healthier, and we've got

some fresh insights into prostate cancer and how hormones can play a key role in the disease.

And that's all on the way, Chris.

Thank you very much, Cannell. This week it's our science phonin extravaganza, so we're going to be taking your science questions and hopefully answering them for you. We've so far heard from Steve. He wants to know, would you bleed blue blood into a vacuum? Answer to that one coming up shortly. Also, pro fran wants to know why things seem to shimmer in the distance on a hot day, and Zach says what would happen if two planets collided? So the answers to all of those are on the way. Plus, we're going to be hearing how the internet is now giving the aviation industry a run for its money when it comes for global warming. We're looking at probably two and a half, three megawatts of heat being rejected from this roof at the moment. To give a sense of how much heat that is, if that were turned into electrical energy, that would be enough to power a thousand homes. Pretty much exactly right, yes. So it sounds like a very hot story. We'll also have the latest on how the Phoenix mission is getting on with its analysis on the surface of Mars.

That's coming up, Dave.

Thanks, Chris, and in this week's kitchen science, I'll be showing you how to create a very unusual and beautiful effect. You'll need some milk, some food colouring and some detergent. Instructions on how to do it, they are on the way. That sounds fab. So if you've got a question for us and the wacky the better, I don't know why I'm saying that, we could get into trouble.
