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.
- Animals
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.

The pebbled path to planets
Small pebbles zipping through a sea of gas may give rise to mighty planets.
- Fossils
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.

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.
- Planets
The Perseverance rover split CO2 on Mars to make breathable air
This oxygen-making experiment shows that astronauts could one day make air to breathe and to help fuel their ride back home.
- Climate
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.
