Chemistry

Simple process destroys toxic and widespread ‘forever’ pollutants

Ultraviolet light, sulfite and iodide break down these PFAS molecules faster and more thoroughly than other methods.

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.

Animals

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.

Chemistry

Let’s learn about diamond

Diamond is born under extreme heat and pressure inside Earth and elsewhere in the universe.

Scientists Say: Fault

A fault is a crack in Earth’s crust where pieces of rock scrape past each other.

Tiny gemstones show when Earth’s crust first started moving

Chemical hints observed in zircons suggest when the important process of plate tectonics first took off.

Cool Jobs: Bringing paleontology to the people

From museums to movies, these three paleontologists totally rock their connections with the public.

Climate

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.

Earth

A new clock shows how gravity warps time — even over tiny distances

This clock measured how gravity changes the passage of time in different places — even spots just one millimeter apart.

Archaeology

Muons reveal the inner worlds of pyramids, volcanoes and more

Tracking these subatomic particles can uncover surprising hidden structures.

Agriculture

Here’s why cricket farmers may want to go green — literally

Crickets are great sources of protein, but they often kill each other in captivity. Green light could help solve the problem, two teens find.

Environment

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.
