Polar bear and insulation

Polar bear and insulation

Author: BBC World Service November 29, 2021 Duration: 20:27

S2 Ep 23. The science behind some fascinating fur could help humans keep warm in space. A polar bear’s fur is brilliant at insulating it from freezing arctic temperatures. Each shaft of hair contains multiple chambers which trap heat close to the skin, making it an incredible thermal insulator. Now, scientists have copied its structure to build a light and flexible material which may be useful for the aerospace industry.

Ever wonder where some of our most ingenious inventions truly began? The answers often lie not in a lab, but in the natural world. 30 Animals That Made Us Smarter, from the BBC World Service, delves into the surprising and brilliant ways animal adaptations have sparked human innovation. Each episode focuses on a specific creature, exploring the unique biological trick it has perfected over millennia and how scientists and engineers have translated that into technology that shapes our lives. You'll hear how the kingfisher's beak inspired a quieter bullet train, or how the humpback whale's flippers led to more efficient wind turbines. This isn't just a list of facts; it's a journey into biomimicry, where stories of natural wonder meet human problem-solving. The podcast reveals a hidden dialogue between species, showing how observing a gecko's foot or a termite mound can lead to breakthroughs in medicine, robotics, and sustainable design. It makes you look at both the animal kingdom and the devices around you with entirely new eyes. With the BBC's signature depth and clarity, this series connects the dots in a way that is genuinely illuminating. Prepare for a collection of stories that are as humbling as they are fascinating, reminding us that some of our smartest ideas have been roaming the planet, swimming the oceans, or flying through the skies for far longer than we have.

How can we prevent millions of birds from being killed by flying into windows? The solution could rest with spiders. Webs containing UV reflective threads deter birds from colliding with them. With Patrick Aryee. To see…
Whale and wind turbine [not-audio_url] [/not-audio_url]

Duration: 14:50
The shape of flippers may help with the efficiency of wind turbines, thanks to humpback whales. Bumps on the edge of their flippers assist them, as they power through water. Biologist Frank Fish discovered this when he s…
Gecko and adhesives [not-audio_url] [/not-audio_url]

Spider and rescue robot [not-audio_url] [/not-audio_url]

Duration: 13:13
Meet the spider-inspired robot that one day might just save your life. Based on how spiders move, it could get to places too difficult for a rescue team to access. Just like our eight-legged friends, it can squeeze aroun…
Shark and hospital surfaces [not-audio_url] [/not-audio_url]

Duration: 13:08
Millions of ridged scales make it difficult for bacteria to attach to the skin of a shark. Can we reduce infections and fight superbugs in a similar way? Have a look at our beautiful animation to see how the shark’s scal…
Albatross and drone [not-audio_url] [/not-audio_url]

Duration: 14:59
Imagine a drone that can fly like the Wandering Albatross. The huge bird harnesses power from the wind and sun and glides over the sea. It is extraordinary. And an engineer has designed a robotic glider that can also rid…
