In How Cold Affects Your Body’s Defenses, host Harith Iskander explains how cold temperatures can impact your body’s ability to fight off infections. When you’re cold, the blood vessels constrict, reducing blood flow to certain areas of the body. This process can weaken the immune system, making it easier for viruses, like the common cold, to take hold. This video is excerpted from BBC’s Got Science?, a science magazine series that explores and explains science in everyday life.
In Bison and Foxes Battle the Cold, narrator Sir David Attenborough takes us through the harsh conditions of the North American prairies, where bison use their strength to uncover food buried beneath the snow, and foxes rely on skill and precision to hunt for meals. This video is excerpted from BBC’s Planet Earth II, a breathtaking documentary series that highlights the natural wonders of our planet.
In A Deep Dive Into Titan’s Mysterious Skies, Professor Brian Cox explains how Saturn’s moon Titan is unique in that it has an Earth-like atmosphere. Its deep, dense atmosphere is rich in nitrogen and contains methane. Though Titan is small, and therefore has weak gravitational pull, it is able to hold onto its atmosphere because the gases are very cold. This video is excerpted from BBC’s Wonders of the Solar System, a spellbinding documentary series that explores the most extreme locations on Earth to explain how the laws of physics carved natural wonders across the Solar System.
In How Trees Prepare for the Toughest Seasons, narrator Sir David Attenborough explains how trees survive harsh winter environments. In northern forests, trees prepare for the cold by pulling water into their trunks and creating a sugary antifreeze. But while most trees lose their leaves, pine trees can survive temperatures as low as -40°F and keep their needles all winter. One special type of pine, the bristlecone, can live for up to 5,000 years, with its cones growing for only six weeks each year. This video is excerpted from BBC's Life, a show that explores the remarkable strategies animals and plants use to ensure their survival.
In The Go Jetters and the Reindeer Herders of Norway, the Go Jetters crew discovesr a herd of reindeer that are migrating through Norway. Ubercorn shares funky facts about how reindeer have adapted to living so far north, and how the Sami people care for them. This video is excerpted from BBC’s Go Jetters, a series that follows the adventures of four international heroes as they travel the globe visiting landmarks and solving environmental problems with Ubercorn, a disco-dancing unicorn.
In The Go Jetters Discover the Magic of Antarctica!, the Go Jetters crew travels to Antarctica, the coldest and windiest place on Earth. In this frozen land, you'll discover huge ice rivers called glaciers, and even hear the ice creak as it moves! Learn all about the South Pole, where penguins live and play, and explore the world’s biggest glacier, the Lambert Glacier. This video is excerpted from BBC’s Go Jetters, a series that follows the adventures of four plucky international heroes as they travel the globe visiting the world’s most famous landmarks with their friend and mentor, Ubercorn, a disco-dancing unicorn.
In A Surprising Discovery in the Cold Seep Ecosystem, narrator Sir David Attenborough explores the cold seep ecosystem. Learn about the ecosystems that scientists have recently discovered in the Gulf of Mexico. This video is excerpted from BBC’s Blue Planet, a definitive documentary series diving into the mysterious depths of the sea to discover the natural history of the world’s oceans and the rarely seen marine life that reside there.
