AI in the classroom: Research focuses on technology rather than the needs of young people
Generative artificial intelligence (AI) such as ChatGPT has arrived in classrooms and sparked an intense debate about its role in education. These technologies raise the fundamental question of which human skills will still matter in the future.
An adolescent growth spurt in young stars helps giant planets form
Stars form in massive clouds of gas called molecular clouds. As they form, they accrete gas from these clouds, and as the stars rotate, gas and dust accumulates in a rotating disk around the star called a protoplanetary disk. As the name makes clear, this is where planets form
Extreme engineering: Unlocking design secrets of deep-sea microbes
The microbe Pyrodictium abyssi is an archaeon—a member of what's known as the third domain of life—and an extremophile. It lives in deep-sea thermal vents, at temperatures above the boiling point of water, without light or oxygen, withstanding the enormous pressure at ocean
Chameleon-like nanomaterial can adapt its color to mechanical strain

The fossil bird that choked to death on rocks, and no one knows why
A fossil only tells part of the story. When an animal's body is preserved as a fossil, there are often pieces missing, and even a perfectly preserved body doesn't tell the whole story of how that animal behaved, how it lived, and how it ultimately died.
