Warning: Wildfires might make you itch
Western wildfires are on the rise due to climate change and land use. Now a study adds eczema to the list of health risks that smoke might trigger.
- Climate
Climate may have sent drift of the North Pole toward Greenland
This mid-1990s shift in the pole’s movement was driven by glacial melt. And that was triggered in part by climate change, a new study reports.

The secret to T. rex‘s incredible biting force is at last revealed
The force of a T. rex bite was roughly 6 metric tons. A new study points to what’s behind that mighty force.
- Space
Stars made of antimatter could lurk in our galaxy
Fourteen sources of gamma rays in our galaxy look like they could be antistars — celestial bodies made of antimatter.
- Chemistry
Scientists Say: Bond
In chemistry, this attachment between atoms forms because of the power of attraction. Chemical bonds make up every solid object on Earth.
- Earth
Only 3 percent of Earth’s land is unchanged by people
A sweeping survey of land-based ecosystems finds that very few still support all the animals they used to. Reintroducing lost species could help.
- Planets
The pebbled path to planets
Small pebbles zipping through a sea of gas may give rise to mighty planets.
- Humans
How scientists can get a better picture of our extinct relatives
Facial reconstructions of extinct species have historically been more art than science. Some researchers hope to change that.
- Brain
Let’s learn about touch
Most senses are concentrated around your head. But touch all over your body, and you need every inch.
- Agriculture
New technologies might help keep drought-prone farms green
After learning how much damage drought can do to crops, two teens designed ways to detect a thirsty plant and make sure it gets enough water.

Local glacier could be gone in a decade, young scientist finds
A teen calculated the volume of a glacier by drilling into it with jets of steam — then used that to estimate how long before all its ice will be gone.
- Plants
Scientists Say: Pollen
Pollen is a mass of tiny reproductive cells. These grains combine with egg cells to form seeds — but on the way, they can make some people miserable.
