Seabirds: Scientists Save Black-Footed Albatross From Rising Sea Levels

Most black-footed albatross nest on sandy beaches in Hawaii—but rising sea levels threaten their eggs and chicks. Researchers in Mexico and the United States came up with a way to save these birds: having young albatross hatch and imprint on an island 6000 kilometers away with higher ground. Watch to see the journey of these black-footed albatross. Read the story: https://www.sciencemag.org/news/2021/…

Science: Rise Of ‘Exascale Supercomputers’ (Video)

The next generation of computing is on the horizon, and several new machines may just smash all the records…with two nations neck and neck in a race to get there first.

The ENIAC was capable of about 400 FLOPS. FLOPS stands for floating-point operations per second, which basically tells us how many calculations the computer can do per second. This makes measuring FLOPS a way of calculating computing power. So, the ENIAC was sitting at 400 FLOPS in 1945, and in the ten years it was operational, it may have performed more calculations than all of humanity had up until that point in time—that was the kind of leap digital computing gave us. From that 400 FLOPS we upgraded to 10,000 FLOPS, and then a million, a billion, a trillion, a quadrillion FLOPS. That’s petascale computing, and that’s the level of today’s most powerful supercomputers. But what’s coming next is exascale computing. That’s zeroes. 1 quintillion operations per second. Exascale computers will be a thousand times better performing than the petascale machines we have now. Or, to put it another way, if you wanted to do the same number of calculations that an exascale computer can do in ONE second…you’d be doing math for over 31 billion years.

Tropical Travel: ‘The Hawaiian Islands’ (Video)

The Hawaiian Islands are an archipelago of eight major islands, several atolls, numerous smaller islets, and seamounts in the North Pacific Ocean, extending some 1,500 miles from the island of Hawaiʻi in the south to northernmost Kure Atoll.

Video timeline: The five largest and most scenic Hawaii islands: Kauai (0:00​), Maui (4:21​), Big Island (8:50​), Molokai (13:18​) and Oahu (15:55​).

Investigations: Chinese Telecomunications Giant Huawei – High Tech or Spy?

Telecommunications giant Huawei is said to be one of the most powerful companies in China. But Huawei has been accused of systematic espionage, and some Western governments doubt whether the company is truly independent of the Chinese government.

This documentary investigates concerns about Huawei and internet security. The company is a major player in the manufacture of smartphones, and enjoys a technological lead in the development of the super-fast 5G broadband network worldwide. But the US and some other Western countries suspect that Huawei works closely with the Chinese government on espionage and sabotage operations.

Has Huawei becomne a pawn in the trade war between the US and China? The arrest of Huawei chief financial officer Meng Wanzhou in Canada in 2018 — at the request of US authorities — marked the climax of the conflict between Huawei and Washington. Some European countries also have concerns about the company.

Does Huawei really have close ties to the Chinese government? And what are the benefits and risks for those foreign clients who choose to work with this 5G giant?

Documentary: ‘The Battle Over Antarctica’ (Video)

The world’s major powers agree: the resources of Antarctica should be exploited peacefully. They have promised to promote peace and scientific research in Antarctica, and to protect its environment. But is this spirit real, or just a lot of talk?

This documentary features interviews with researchers, activists, diplomats, and military personnel from Spain, Russia, Portugal, Chile, Argentina, and the United States. There’s been much debate over how to share control of resources in Antarctica, which is the world’s oldest ecosystem. Critics say that behind the scenes, a game of high-stakes poker is underway. Could this competition end in armed conflict? Or will Antarctica serve as a model for peaceful international cooperation? This film addresses these complicated issues with in-depth analysis, accompanied by magnificent images of the Antarctic landscape. The documentary’s soundtrack was composed by Javier Weyler, former drummer of the Welsh rock band, the Stereophonics.

Arctic Journey: From Greenland To Alaska

Two film crews explore the spectacular wilderness of the Arctic. The people who live there face dramatic changes.

Part two takes viewers from East Greenland to Alaska. The region around the North Pole is one of the greatest and least-known wildernesses in the world – and it’s rapidly changing due to global warming. 350 people, most of them Inuit, live in Ittoqqortoormiit in Greenland. The nearest settlement is on neighboring Iceland. Almost 800 kilometers of Arctic Ocean separate the two islands. The film team accompanies an Inuit family through Scoresby Sound, a fjord system on the eastern coast of Greenland.

They travel hundreds of kilometers in small boats through pack ice, passing icebergs as high as skyscrapers. On the way they meet whalers who are hunting for narwhals in summer. In this Inuit culture, narwhal skin and polar bear goulash have ensured survival for thousands of years. Greenpeace and WWF activists want to stop whaling and polar bear hunting – but this poses a threat to the indigenous way of life on Greenland.

On the expedition through the world’s largest fjord system, the team learns about the consequences of global warming: melting permafrost and a rapid increase in greenhouse gases. The changes are worrying. Some say they have brought benefits to the far north — the ice breaks up earlier and so too does the hunting season. However, the risks outweigh this benefit. The knowledge and way of life that have been passed down from generation to generation may soon be unsustainable.
