Heat waves appear more life-threatening than scientists once thought
This is bad news as a warming planet leads to growing numbers of excessive heat waves — and millions more people facing potentially deadly temperatures.

Scientists Say: Humidity
Feel sticky when you step outside on a summer day? Blame humidity — water in the air.

Wildfire smoke seems to pose its biggest health risk to kids
New studies, some of them in young monkeys, point to vulnerabilities affecting kids' airways, brains and immune systems.

Western wildfire smoke poses health risks from coast to coast
As wildfires become more common, their hazardous smoke is sending East Coast residents — especially children — to emergency rooms.

Whale sharks may be the world’s largest omnivores
Chemical clues in the sharks’ skin show that the animals eat and digest algae.

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.

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.

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.
