The central idea is integration rather than addition. AQUA HUMAN ditches the external tanks and brings breathing, temperature regulation, and mobility into the suit's structure itself, functioning as a single synchronized system.

The UK Health Security Agency reported around 1,504 heat-associated deaths in England during summer 2025, roughly half the predicted 3,039, despite the season being the warmest on record.

The study highlights how rapid Arctic warming increases the frequency of extreme weather events, particularly concurrent heatwaves across Europe and eastern Asia.

Coles' brain was preserved with a slurry of 'cryoprotective' chemicals, and despite expectations of damage, the tissue structure survived with relative vigor.

There's a glorious smugness that can only be experienced by exercising outdoors in winter conditions. The fresh air, the endorphins, the reduced risk of heart disease they're all nice bonuses, but nothing beats that knowing nod from another rain-drenched runner, or the horrified faces of nearby dog walkers as you stride confidently into the sea for a winter dip.

I don't know who invented this crazy challenge, but the idea is to put someone in a carved-out ice bowl and see if they can get out. Check it out! The bowl is shaped like the inside of a sphere, so the higher up the sides you go, the steeper it gets. If you think an icy sidewalk is slippery, try going uphill on an icy sidewalk. What do you do when faced with a problem like this? You build a physics model, of course.

He had flown in from Mar-a-Lago and, he told me, was there to observe. The next day, he watched as Åsa Rennermalm, a Rutgers University professor who studies polar regions, sat onstage with European foreign ministers and spoke out against cuts to U.S. science funding. "A leading US Arctic scientist is on stage absolutely ripping her country to the delight of the audience," Dans wrote on X. "Embarassing." He punctuated his post with an American-flag emoji.

Wind chill is a measure of how quickly bodies lose heat when you combine low temperatures with high winds. And wind chill conditions can be dangerous. "The stronger the winds [and] the colder it is, the more likely you are to develop frostbite in a short amount of time or hypothermia," says Jessica Lee of the National Weather Service's Weather Prediction Center.

These freezers operate under extreme thermal and electrical conditions. Exposure to subzero environments, high-powered compressors, and sensitive control systems creates risks that demand structured procedures. Facilities that rely on equipment like a freezer -40C, must apply disciplined handling standards to protect both staff and stored materials.

That seemingly paradoxical dynamic results from several factors. Foremost among them is the rebound of land beneath the Greenland Ice Sheet, a mile-thick body of glacial ice that covers 80 percent of the island and is being lost to melting at a rate of roughly 200 billion tons each year. As the ice sheet loses mass, the land beneath rises.

'They save up ice like a savings account and then spend it all very quickly like a Black Friday event.'

Decades of successful scientific collaboration could be at risk if Europe-US political relations continue to fray over trade and defense issues. For more than 30 years, Arctic nations have worked together across the physical, biological and social sciences to understand one of the world's fastest changing regions. Since the late 1970s, the Arctic has lost around 33,000 square miles of sea ice each year roughly the same area as Czechia.

Polar bears are the poster children of climate changeand for good reason. These giant bears hunt, mate and spend their days hanging out on Arctic sea ice, which is rapidly disappearing as the climate warms. But some polar bears, it seems, are far more resilient than we realized: new research suggests that in one region, the bears are adapting to the declining sea ice.

Green iguanas (Iguana iguana) are not native to the U.S. but were brought to Florida in the 1960s, where they have, for the most part, flourishedexcept, that is, when temperatures have dropped below 50 degrees F (10 degrees C). These chilly conditions can cause a cold shock in the lizards. And because the iguanas tend to sleep in trees, getting cold shocked can sometimes cause the animals to fall from the skies in an infamous Florida phenomenon.

During a rare break in the weather, the NYT says helicopters airlifted the researchers and their equipment 19 miles to their planned outpost site on top of the glacier. The two helicopters involved flew a dozen total loads of cargo from the icebreaker ship to the camp site, while glacial scientists and engineers erected a small tent city, complete with bathrooms, generators, and a mess hall.
