Psychedelic drugs can trigger characteristic hallucinations, which have long been thought to hold clues about the brain’s circuitry. After nearly a century of study, a possible explanation is crystallizing.
In a renewed attempt at a grand unified theory of brain function, physicists now argue that brains optimize performance by staying near — though not exactly at — the critical point between two phases.
The renowned British physicist, who died at 76, left behind a riddle that could eventually lead his successors to the theory of quantum gravity.
Does the force of gravity change at large scales? Perhaps not, but a new theory of dark matter shows why that could appear to be the case.
A different kind of dark matter could help to resolve an old celestial conundrum.
Juggling has advanced enormously in recent decades, thanks in part to the mathematical study of possible patterns.
The ancient creatures who first crawled onto land may have been lured by the informational benefit that comes from seeing through air.
A new theory explains how fragile quantum states may be able to exist for hours or even days in our warm, wet brain. Experiments should soon test the idea.
Researchers are uncovering the hidden laws that reveal how the Internet grows, how viruses spread, and how financial bubbles burst.
