Global warming may have halted a glacial period already underway: an Arctic ice cap began expanding about 2,000 years ago, then started shrinking in the 1960s. @columbiaclimate @sciencemagazine phys.org/news/2026-10-global…

Global warming may have halted an emerging ice age, study suggests

Two thousand years ago, the Arctic remnants of a once-vast ice sheet started to grow again. It was the beginning of a new glacial period, more conversationally known as the next ice age—but by the...

Quantum interference has trapped electron waves in a metal for the first time, binding them near atomic defects in Pd₅AlI₂ despite available escape paths. @columbia @NaturePhysics @sciencemagazine phys.org/news/2026-10-quantu…

Quantum interference traps electron waves in metal for first time

Ever since quantum mechanics first described particles, like electrons, as rippling waves, researchers have wondered if those waves could be trapped in place. Writing today in Science a century...

A weaker, slower brain signal may link several schizophrenia symptoms: people with the largest signal differences tended to have worse timing difficulties, more disorganized speech and more severe symptoms. @mcgillu @ScienceAdvances medicalxpress.com/news/2026-…

Imaging study links several schizophrenia symptoms to a single brain signal

Schizophrenia is often described as a list of separate problems. People may perceive the world differently, act on their surroundings differently or speak in ways that are hard to follow. A new study...

AI agents invented games on virtual islands without assigned tasks, improvising versions of bowling, basketball and juggling during 30 hours of exploration. @arxiv techxplore.com/news/2026-10-…

Strand AI on a desert island, and it starts playing and inventing games

AI agents tend to do things when we give them specific commands, such as analyzing data and answering questions. But what would they do if left to their own devices?
