Explainer: What is chaos theory?

Chaos can help scientists explore subjects from climate change to human brains. Learn about the theory behind this field of science.

Animals

Scientists Say: Coral

Over 4,000 species of fish make their home among the reefs created by these colony-dwelling marine animals.

Climate

Explainer: What is an atmospheric river?

These long-traveling storm systems bring moisture to many parts of the world. Here’s what scientists are learning about them.

Climate

For greener toilets and air conditioning, consider saltwater

Using saltwater would allow coastal cities to save their freshwater for drinking and to reduce their carbon footprints. Some could save money, too.

Environment

Fungi help rescue crops being harmed by microplastics

Microplastics in the soil hinder plant growth. But two finalists at Regeneron ISEF found that fungi and farm waste can reduce the harm.

Fossils

Ancient jellyfish? Upside down this one looks like something else

A new look at an ancient sea animal called Essexella suggests it may have been a type of burrowing sea anemone, not a floating jelly.

Tech

Nanocrystal ‘painted’ films may someday help relieve summer heat

The rainbow palette and cooling powers of new plant-based films comes from their microscopic surface patterns of tiny crystals.

Tech

A device spots and counts honeybees hosting a dangerous parasite

At Regeneron ISEF, three teens debuted an infrared system to detect honeybees carrying mites. It can show beekeepers when a colony needs to be treated.

Environment

Older diesel school buses linked to more student absences

Schools that replaced or upgraded old diesel school buses increased student attendance rates, new research shows.

Environment

Making yards more diverse can reap big environmental benefits

Replacing grass with native plants uses less water and fewer chemicals while providing additional benefits to people and wildlife.

Earth

Under the ice, a hidden lake hints at its origin — and coming end

Lake Mercer may serve as a model for better understanding the birth and life of Antarctica’s hundreds of subglacial lakes.

Earth

A natural ‘cathedral’ lurks deep under Antarctic ice

By drilling into this cavern, scientists have opened a window into the mysterious world of hidden lakes, their occupants — and rivers that run uphill.
