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.

This glitter gets its color from plants, not a synthetic plastic
In the new material, tiny arrangements of cellulose reflect light in specific ways to create vibrant hues in an environmentally friendly glitter.

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.

Scientists Say: Savanna
Savannas exist where there is more rainfall than in a desert, but less than in a forest.

A new way to make plastics could keep them from littering the seas
Borrowing from genetics, scientists are creating plastics that will degrade. They can even choose how quickly these materials break down.

Secret forest fungi partner with plants — and help the climate
Forest fungi are far more than mere mushrooms. They explore. They move nutrients and messages between plants. They can even help fight climate change.

Explainer: The age of dinosaurs
Take a trip back to the Mesozoic Era to explore how geologic events, ecosystems and evolution were connected during the so-called age of dinosaurs.

The ultimate genealogical search hunts for our earliest ancestors
The complex search to identify humans’ most distant cousins is long, complex and far from straightforward. It’s also far from over.

Scientists Say: Avalanche
The word avalanche usually refers to a huge snowslide down a mountain, but it can also be used to describe any large mass of material tumbling downhill.

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.
- Climate
Scientists Say: El Niño and La Niña
El Niño and La Niña are part of a climate cycle that results in major weather changes every few years.
