Healthy soils are life-giving black gold
Scientists explain why everyone needs to value the soils beneath our feet — and why we should not view them as dirt.
- Agriculture
Soil (and its inhabitants) by the numbers
Teeming with life, soils have more going on than most of us realize.

Honeybees fend off deadly hornets by decorating hives with poop
Bees usually collect pollen and nectar. Scientists were surprised to find that Asian honeybees also gather animal dung to defend their hives.

Dew collector brings water to thirsty plants
This invention grabs water from the air at night. All it needs is the sun’s warmth the next day to release that moisture to growing plants.

How to grow your own science experiment
Does fertilizer help plants grow better? You might expect it to, but how can you know? This experiment will help you test it yourself.

Learning what stresses queen bees could save their hives
Beehives often die off after the queen gets too stressed to make enough babies. New tests could identify what stressed her — and point to solutions.
- Climate
Student scientists work to help all of us survive a warmer world
From glaciers in the refrigerator to a rover in the field, here’s how young scientists are looking to help us adapt to climate change.

Scientists Say: Carbohydrate
Carbohydrates are molecules with carbon, oxygen and hydrogen. Animals break down these chemicals in food to get energy.

Pesticides contaminate most food of western U.S. monarchs
Monarch caterpillars eat only milkweeds. A new study finds widespread pesticide use has tainted these plants across the insect’s western U.S. breeding grounds.
- Ecosystems
Scientists Say: Prairie
Prairies are flat, fertile grasslands in North America. They are their own unique ecosystem.

Let’s learn about rain
People need rain for their crops and their drinking fountains. But there sometimes can be too much of a good thing.
- Plants
Let’s learn about trees
These long-lived woody plants provide shade for people, homes for animals — and help protect the planet against climate change.
