An AI fed raw collider data reproduced famous particle masses on its own
A computer model was fed about a billion real particle collisions and told almost no physics. The fake collisions it then produced show the correct masses of several known particles, matching values physicists had already measured.

Today's best AI models often fail at simply copying text back exactly
Leading AI chat models make mistakes when asked to repeat a piece of text word for word. On long, repetitive text, five top models copied it correctly less than half the time.

A tiny robot that folds from a hand into a walking humanoid
Researchers built one small 27-joint robot whose parts rearrange to become either a five-fingered hand or a mini walking humanoid. The same hand fingers slide down to become the robot's legs and arms.

A protein-folding AI may secretly hold clues about how proteins move, not just their final shape
AlphaFold2 is a program that predicts a protein's folded shape. By gently blurring and shrinking the numbers inside it, a researcher pulled out a range of shapes that matched how one real protein bends and comes apart in physics simulations.
