Views: ‘Argentina – Falls, Glaciers & Mountains’ (4K)

Argentina, officially the Argentine Republic, is a country located mostly in the southern half of South America.

Sharing the bulk of the Southern Cone with Chile to the west, the country is also bordered by Bolivia and Paraguay to the north, Brazil to the northeast, Uruguay and the South Atlantic Ocean to the east, and the Drake Passage to the south. With a mainland area of 2,780,400 km2 (1,073,500 sq mi),[B] Argentina is the eighth-largest country in the world, the fourth largest in the Americas, the second largest in South America after Brazil, and the largest Spanish-speaking nation by area. The sovereign state is subdivided into twenty-three provinces (Spanishprovincias, singular provincia) and one autonomous city (ciudad autónoma), Buenos Aires, which is the federal capital of the nation (Spanish: Capital Federal) as decided by Congress.[18] The provinces and the capital have their own constitutions, but exist under a federal system. Argentina claims sovereignty over part of Antarctica, the Falkland Islands (Spanish: Islas Malvinas), and South Georgia and the South Sandwich Islands.

Arctic Travel: Iceland’s ‘Vatnajökull’ – Largest Glacier In Europe (Video)

Iceland truly is the land of fire and ice – aside from having some of the world’s most active volcanoes, it’s also home to Europe’s largest glacier: Vatnajökull. The Vatnajökull glacier stretches some 143 kilometers east to west, and over 98 kilometers north and south, holding a massive 3000 cubic kilometers of pure ice. As well as the breathtaking hiking routes across the glacier, there are also many beautiful blue ice caves to take you quite literally into the heart of the glacier. Our Euromaxx-Reporter Hendrik Welling went to Iceland to find out what makes this mountain of ice so amazing.

Vatnajökull is the largest and most voluminous ice cap in Iceland, and the second largest in area in Europe after the Severny Island ice cap of Novaya Zemlya. It is in the south-east of the island, covering approximately 8% of the country. 

Travel & Science Videos: ‘Everest Glaciology – Truth In The Ice’ (NatGeo)

As part of the National Geographic and Rolex Perpetual Planet Everest Expedition, a team of scientists and Sherpa guides sets out to collect information about glacial change in the Himalayas. By extracting ice cores from the highest glacier in the world, the team has begun to uncover details about climate change that have – until now – been hidden in this hard-to-reach ice. The National Geographic Society uses the power of science, exploration, education, and storytelling to illuminate and protect the wonder of our world.

Top New Science Podcasts: Cooling Computer Chips, Covid-19 & Avalanches

Nature looks at: Keeping electronics from overheating, Covid-19 changes, and how to include minority populations in genetic analyses.

In this episode:

00:46 Cool computers

Keeping components cool is a major hurdle when it comes to increasing electronic power. This week, we find out about a new way to integrate tiny microfluidic channels directly into circuits, to help keep them cool. Research Article: van Erp et al.

06:57 Coronapod

By comparing coronavirus genomes taken from people around the world, researchers are getting an idea of how SARS-CoV-2 is changing as it spreads. We discuss a particular genetic mutation that rapidly became dominant early in the pandemic, and the effect it may have had on the outbreak. News: The coronavirus is mutating — does it matter?

21:41 Research Highlights

How rock avalanches can cause destructive air blasts, and melting glaciers cause lakes to grow. Research Highlight: The violent blasts that can add to an avalanche’s devastationResearch Article: Shugar et al.

23:59 The people left out of genetic studies

Minority populations are often underrepresented in genetic study recruitment. However, even when data about them is collected it may go unused. We find out why, and what can be done about it. Comment: Don’t ignore genetic data from minority populations

30:51 Briefing Chat

We discuss some of the latest stories highlighted in the Nature Briefing. This week we discuss how bacterially-infected mosquitoes could curb dengue fever, and some surprisingly large black holes. Nature News: The mosquito strategy that could eliminate dengueNature News: ‘It’s mindboggling!’: astronomers detect most powerful black-hole collision yet

Travel & Exploration: The “Changing Glaciers Of Iceland” (NatGeo Video)

National Geographic Explorer M Jackson is fascinated by glaciers. That fascination takes her to Iceland where she tromps through ever-shifting ice tunnels and leads local students to see their country’s largest and most endangered glacier. The National Geographic Society uses the power of science, exploration, education, and storytelling to illuminate and protect the wonder of our world.

Top New Science Podcasts: Covid-19 Inflammatory Response, Glacier Retreat

science-magazine-podcastsFirst up this week, Staff Writer Jennifer Couzin-Frankel talks with host Sarah Crespi about a rare inflammatory response in children that has appeared in a number of COVID-19 hot spots. 

Next, Julian Dowdeswell, director of the Scott Polar Research Institute and professor of physical geography at the University of Cambridge, talks with producer Meagan Cantwell about tracing the retreat of Antarctica’s glaciers by examining the ocean floor. Finally, Kiki Sanford interviews author Danny Dorling about his new book, Slowdown: The End of the Great Acceleration―and Why It’s Good for the Planet, the Economy, and Our Lives.
