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.

Let’s learn about the science of the Winter Olympics
From scientific innovations to climate change and weather, there’s plenty of science to be found among the feats of amazing athleticism.

The ‘Doomsday’ glacier may soon trigger a dramatic sea-level rise
The ice shelf that had kept it in place could fail within five years. That would speed the glacier’s slip into the ocean, boosting a rise in sea levels.

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.

In blazing heat, some plants open leaf pores — and risk death
When heat waves and droughts collide, water is precious. Some thirsty plants try to cool off by opening tiny pores — only to lose water even faster.

Rewilding returns lost species to strengthen ecosystems
Restoring the missing species can help undo human-caused problems by aiding forests, slowing climate change and reducing wildfires.

Climate change is upping the height of Earth’s lower atmosphere
The upper edge of the troposphere, the slice of sky closest to the ground, rose 50 to 60 meters (165 to 200 feet) a decade from 1980 to 2020.

Can scientists develop an icy sanctuary for Arctic life?
The final refuge for summer sea ice may also protect the creatures that depend on it. Saving it is an ambitious goal with many hurdles.

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.

Analyze This: Nutrients from sewage may harm coastal ecosystems
A new model suggests that 58 percent of coral reefs and 88 percent of seagrass beds are exposed to excess nitrogen from wastewater.

Leaky sewer pipes pollute urban streams and bays with drugs
Scientists find that leaking sewer pipes around Baltimore, Md., spew thousands of doses of medicines into the Chesapeake Bay and other waterways.

Everyday plastics can pollute, leaching thousands of chemicals
Plastic bags and containers leach potentially toxic chemicals into both food and water, but researchers yet don’t know how they might affect health.
