Hello, welcome along to a brand new Fun Kids Science Weekly. This is the only podcast that has a real search of the solar system that finds any science secrets squirreling away within. My name is Dan, and let's get to it.

This week, we'll answer some of your questions. You can always send them as a voice note to me on the free Fun Kids app.

And we're trying to find out how fish managed to breathe, even though they're, well, underwater.

Like us, fish have to get oxygen.

And rather like we have our own lungs, they have an organ, a special part of their body that is specifically

designed to get as much oxygen out the water as possible, and that's called their gills.

Also, our battle of the sciences this week takes us into the world of cognitive neuroscience,

so it's all about your brain and why it thinks the way it does.

And your brain is one of the most amazing things in your body.

It's like a super powerful computer that controls absolutely everything you do, from breathing

to walking, thinking and feeling.

And we're climbing trees in Indonesia to track down our dangerous Dan beast this week.

So let's get going with a brand new Fun Kids Science Weekly.

And we start with your science in the news. A badly burnt scroll from the Roman town of Herculaneum has been

digitally unwrapped, providing the first look at what's written inside for 2,000 years.

Now, the document, which looks like a big lump of charcoal, really, was charred by the volcanic eruption

of Mount Vesuvius back in 79 AD, and is too fragile to ever be physically opened.

But scientists have done something really incredible. They've used

a combination of x-ray imaging and artificial intelligence to like virtually unfurl it. They've managed

to scan it even though it's tightly packed in and they can read it on the computer, revealing rows and

columns of texts. Now some letters are already very visible in this ancient

scroll, and the team believes it's a work of philosophy, but they do say that more work is needed
