Uplifting Antarctic shores point to accelerating loss of glaciers
It appears the Pine Island and “Doomsday” Thwaites glaciers are losing ice — and shrinking faster — than at any time in the past 5,500 years.

Some Greenland polar bears are surviving with very little sea ice
The ‘glacial mélange’ on which they’ve come to rely — a mix of ice, snow and slush — could be a temporary refuge for some polar bears.

Palm-size marsupials may face extinction from wild ‘house’ cats
After surviving Australian bushfires, the Kangaroo Island dunnart is losing ground as it's targeted by hungry predators.

Let’s learn about amphibians
Amphibians are named after the Greek word for “double life” because many transform from water dwellers to landlubbers as they grow up.

Coastal cities around the world are sinking, satellite data show
Of 99 coastal cities studied, nearly one-third are sinking. This leaves coastal communities increasingly vulnerable to rising seas.
- Chemistry
Reusable plastic bottles release hundreds of pollutants into water
Data show the plastic ends up tainting drinking water. For now, scientists don’t know what health risks downing these pollutants might pose.

Bubbles could help remove trash from rivers
One young engineer devised a way to make bubbles sweep away the trash floating down a creek, like the one in her backyard.

Let’s learn about cellulose
The world’s most abundant natural polymer is finding all kinds of new uses, in everything from ice cream to construction.

Scientists Say: Atmosphere
An atmosphere is an envelope of gas around a planet, dwarf planet or moon.

Night lights make even the seas bright
Light from coastal cities and offshore development may shine deep enough to disrupt tiny critters living dozens of meters (yards) below the surface.

Ponds made to control floods can spew climate-warming gases, study finds
Younger stormwater ponds can release more carbon in gases than they absorb, a study finds. That could aggravate global warming.

Analyze This: Corals stash microplastics in their skeletons
Scientists have wondered where the ocean’s microplastic pollution ends up. Corals may trap about 1 percent of particles in tropical waters each year.
