This Sticker Absorbs Sweat—and Might Diagnose Cystic Fibrosis

In the Middle Ages, a grim adage sometimes turned up in European folklore and children’s stories: Woe to that child which when kissed on the forehead tastes salty. He is bewitched and soon must die. A salty-headed newborn was a frightful sign of a mysterious illness. The witchcraft diagnosis didn’t hold, of course, but today… Okumaya devam et This Sticker Absorbs Sweat—and Might Diagnose Cystic

Variant Hunters Race to Find New Strains Where Testing Lags

In the past year, emerging variants have changed the calculus of the pandemic, forcing countries back into lockdowns and to reconsider vaccine strategies. Basically, it’s now a race: Getting shots to more people will help quell the variants’ spread and slow the emergence of new ones. But in Africa, where only a few countries have… Okumaya devam et Variant Hunters Race to Find New Strains Where Testing

The Thrusters Behind NASA’s Mission to the Asteroid Psyche

A satellite company named Maxar recently delivered a passenger-van-sized chunk of spacecraft to NASA’s Jet Propulsion Laboratory in California. This chassis will serve as the backbone for a robotic spacecraft that will explore a metallic asteroid for the first time. This ambitious mission, named Psyche after the eponymous asteroid it will explore, is due to… Okumaya devam et The Thrusters Behind NASA’s Mission to the Asteroid

In Europe, Backlash Heats Up Over Garbage Incinerators

What’s more, Vähk warned, the EU’s aim for countries to landfill no more than 10 percent of municipal waste by 2035 will unintentionally bolster incinerators’ appeal. “There’s a lot of pressure on minimizing landfill,” he said. That’s worrying, “because we don’t want to move from landfilling to incineration.” It all comes as the EU is… Okumaya devam et In Europe, Backlash Heats Up Over Garbage

A ‘Last Hope’ Experiment Finds Evidence for Unknown Particles

The Theory Initiative decided not to include BMW’s value in their official estimate for a few reasons. The data-driven approach has a slightly smaller error bar, and three different research groups independently calculated the same thing. In contrast, BMW’s lattice calculation was unpublished as of last summer. And although the result agrees well with earlier,… Okumaya devam et A ‘Last Hope’ Experiment Finds Evidence for Unknown

Pandemic Lockdowns Did Cut Air Pollution—but With a Catch

Last April, as people around the world sheltered in place against the Covid-19 pandemic, The Indian Express newspaper published a photo that had gone viral on Twitter, showing a slightly hazy deep blue sky over Uttar Pradesh, the most populous state in northern India. Above a garden trellis, the angular, white peaks of the Himalayan… Okumaya devam et Pandemic Lockdowns Did Cut Air Pollution—but With a

Plastic Is Falling From the Sky. But Where’s It Coming From?

These microplastics aren’t just washing ashore and accumulating on beaches. When waves crash and winds scour the ocean, they launch seawater droplets into the air. These obviously contain salt, but also organic matter and microplastics. “Then the water evaporates, and you’re left just with the aerosols,” or tiny floating bits of particulate matter, says Cornell… Okumaya devam et Plastic Is Falling From the Sky.

Did This Scorching-Hot Planet Lose—and Regain—an Atmosphere?

Laura Kreidberg, who directs research on exoplanet atmospheres at the Max Planck Institute, would like to see an independent analysis of the data before jumping to conclusions. “There are a lot of little decisions in the data processing that can produce unexpected bumps and wiggles,” says Kreidberg. “I’d like to see the spectrum reproduced by… Okumaya devam et Did This Scorching-Hot Planet Lose—and Regain—an

Will Future Electric Vehicles Be Powered by Deep-Sea Metals?

Both expeditions will collect baseline environmental data on the kinds of marine organisms that live on the seafloor, the composition and chemistry of bottom sediments, and the flow of underwater currents at different depths. Knowing these control measurements will be important in determining whether such mining can be done without destroying the underwater habitat. “Our… Okumaya devam et Will Future Electric Vehicles Be Powered by Deep-Sea
