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.
- Computing
Teen-created software IDs skin conditions, risky drivers and more
Researchers at the 2023 Regeneron ISEF unveiled computer programs to diagnose skin conditions, warn of dangerous driving and translate sign language.
- Math
Math explains why dense crowds form surprisingly orderly lines
New research into the behavior of moving groups of people adds to decades of study on the wisdom of crowds.
- 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.
- Math
Scientists Say: Parabola
A parabola is a U-shaped curve, where every point along that curve is the same distance from another point and a line.
- Humans
Race car drivers usually blink at the same places in each lap
Blinking is usually thought to be somewhat random. But a new study tracking blinks in Formula One drivers shows it can be predictable — and strategic.
- Brain
Neuroscientists use brain scans to decode people’s thoughts
The research may lead to new devices for people who can’t communicate easily. It also raises privacy concerns.
- 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.
- Math
Scientists Say: Ellipse
Ellipse describes the shapes of planetary orbits around their stars and explains the wacky acoustic phenomenon of “whispering chambers.”
- Fossils
T. rex may have hidden its teeth behind lips
Dinosaurs like Tyrannosaurus have long been portrayed with their big teeth bared. But new research suggests this wasn’t so.
- Math
An ‘einstein’ shape eluded mathematicians for 50 years. Now they found one
The shapes can form an infinite tiled pattern that never repeats. The first is a 13-sided shape nicknamed “the hat.”
