Teen inventors say: There’s got to be a better way
Finalists in the 2022 Regeneron Science Talent Search are revamping prostheses, earthquake safety systems and air travel.

Satellites find big climate threats — ultra-emitters of methane
Eyes in the sky show many of the worst methane emitters are in countries that produce a lot of oil and gas, such as Russia and the United States.
- Chemistry
New process can transform urban CO2 pollution into a resource
Researchers have developed a liquid metal that breaks down carbon dioxide in the air, converting it from a climate threat into a valuable raw material.

Clothes dryers may be a major source of airborne microplastics
Scientists thought washing machines were a leading contributor of microplastics. Now it appears dryers may be an even bigger problem.

Analyze This: Masks cut the distance that spit droplets fly
Both cloth masks and surgical masks reduced the distance spit traveled from a person talking or coughing by at least half, compared with no mask.

Recycling a climate-warming gas could make ‘greener’ farmed fish
Instead of warming the climate, methane gas can be collected to help farmers. Along the way, it may also save some fish.

Snail slime + gold could boost the power of sunscreens and more
These two strange ingredients could make skin-care products that are better for both our skin and the environment.

Could reusable ‘jelly ice’ cubes replace regular ice?
These hydrogel “jelly ice cubes” are made mostly of gelatin and water. They won’t melt, even when thawed, and may provide new food cooling options.

From icebergs to smoke, forecasting where dangers will drift
Smoke drifts. Fish eggs float downstream. Where such drifting things end up may seem a mystery. But research can predict where they’ll end up.
- Microbes
Genes point to how some bacteria can gobble up electricity
A new study shows how some microbes absorb and release electrons — a trait that may point to new fuels or ways to store energy.

Vikings were in North America 1,000 years ago
Wooden objects provide the most precise dating yet for a Viking settlement on the coast of Newfoundland in Canada.
