Warm feathers may have helped dinos survive mass Triassic die-off
Dinosaurs may have weathered freezing conditions about 202 million years ago, thanks to warm feathery coats.

Let’s learn about heat waves
Heat waves often occur when a high-pressure system lingers over a certain area. These deadly events are on the rise due to climate change.

Earth’s rock collection hints at how to search for life elsewhere
A new way to sort minerals focuses on how they formed. It provides new clues about Earth’s crystal past and how to find life on other planets.
- 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.

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.

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.

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.
