Summary

Get ready for another BIG and BRILLIANT adventure into the wonders of science on this week’s Science Weekly!

This episode plunges us deep beneath the waves as we uncover how dolphins and other ocean animals manage to hold their breath for astonishing lengths of time. Then, we shift from sea to psychology as Battle of the Sciences takes us inside the human mind to explore how thoughts, feelings, and behaviours can shape our physical health.

In Science in the News, Australian tropical rainforests have shocked scientists by releasing more carbon than they absorb. We’re also heading to Wales, where plans for a ground-breaking nuclear power station are underway. And Barny Reed from the RSPCA joins Dan to explain how the UK is moving toward more humane animal testing.

Then it’s over to your questions! Misha wants to know how braces work, and Alison Wood from Whale and Dolphin Conservation reveals how dolphins hold their breath for so long.

Dangerous Dan returns with the grolar bear, a rare hybrid of a grizzly and a polar bear.

And in Battle of the Sciences, Mark McDermott champions health psychology, showing how the way we think and feel can affect our bodies.

Plus, Marina Ventura dives back in with another Ocean Adventure, exploring how oceans help humans survive and thrive.

This week, we learn about:
– How dolphins stay underwater for so long
– Why some rainforests are releasing carbon
– How braces straighten teeth
– What makes the grolar bear so unusual
– How psychology affects your health

All that and more on this week’s Science Weekly!

Welcome along, explorer. Quick question, who's ready for an adventure? Good. I'd hope you'd say that,

0:06.8

because we're on wrong right now. It's time to leave planet Earth and search out the solar system in a brand new Fun Kid Science Weekly.

0:14.7

My name is Dan. This is where we find all that really genius science that's lurking through the universe. And this week we're going underwater, plunging deep down into the ocean to discover

0:25.7

how creatures there stay beneath the waves for so long.

0:31.1

The record-breaking ones can hold their breath for about two hours.

0:35.1

And they go right to the deep ocean depths to search for

0:38.9

giant squid, colossal squid, deep living animals like that, whereas dolphins, they feed much,

0:45.1

much closer to the surface. Also, we're on a mission inside your mind investigating why you think,

0:52.4

feel and act the way that you do.

0:56.5

When you reward a bit of behaviour, you change the likelihood of it happening in the future.

1:03.4

And these rewards can be all sorts of things.

1:05.7

It could just simply be a smile in a conversation with somebody else.

1:10.1

Oh, somebody smiled at me.

1:11.4

Perhaps I'll say that thing again.

1:12.8

They like my joke.

1:14.8

And we're taking a look at a brilliant, strange hybrid bear.

1:18.6

It's all on the way in a brand new Fun Kids Science Weekly.

1:25.7

Let's start with your science in the news.

1:28.3

Australian tropical rainforests have become the first in the world to give out more carbon than they absorb.

1:34.3

This is a problem because carbon helps to heat the world.

1:37.3

It's one of the causes of the climate crisis.

1:40.3

And rainforests are usually thought of as carbon sinks.
