Stone Age People Brutalized Their Prisoners of War, New Evidence Suggests

gizmodo.com Margherita Bassi 2025-11-10 08:00:20

When we think of Stone Age people, most imagine small communities living in caves, cutting into their most recent hunt with primitive tools, and imitating their environment with illustrative rock art. People during the Neolithic, however—the last stage of the Stone Age (around 9000 to 3300 BCE)—also waged wars and absolutely demolished their enemies. In a study published today in the journal Science Advances, researchers present horrific evidence suggesting that Neolithic people in northeastern

Researchers Find Strange Link Between Marathon Running and Cancer

gizmodo.com Ed Cara 2025-11-12 16:50:30

Some of the most physically fit people in the world may have a unique health risk. New research uncovers a possible link between marathon running and colorectal cancer. Oncologists at the Inova Schar Cancer Institute in Virginia conducted the study, which examined the colons of relatively young people who had run several long-distance races. They found these runners had a much higher rate of having potentially dangerous adenomas (a type of polyp) than would be expected for their age. Though the

Psychiatrists Warn That Talking to AI Is Leading to Severe Mental Health Issues

In a jarring new analysis, psychiatric researchers found that a wide swath of mental health issues have already been associated with artificial intelligence usage — and virtually every top AI company has been implicated. Sifting through academic databases and news articles between November 2024 and July 2025, Duke psychiatry professor Allen Frances and Johns Hopkins cognitive science student Luciana Ramos discovered, as they wrote in a new report for the Psychiatric Times, that the mental healt

These Chunks of Ice Move All By Themselves, Thanks to a Cool Engineering Trick

gizmodo.com Margherita Bassi 2025-11-16 06:20:54

It looks like something straight out of a Ouija board horror movie, but frosty—researchers have figured out how to make ice move by itself. A video capturing the creepy dynamic features an ice disk melting on a metal surface etched with an asymmetrical herringbone pattern. The ice and its small puddle slowly start to move sideways before suddenly picking up speed and slingshotting across the metal plate. The researchers suggest that this sort of independent movement could one day generate power

Scientists Identify a New Glitch in Human Thinking

Good news, everyone! Scientists at the University of California, Berkeley, have coined a new term to describe our brains being dumb. In a recent study, they provide evidence for a distinct but common kind of cognitive bias—one that makes us reluctant to take the easier path in life if it means retracing our steps. The researchers have named the bias the “doubling-back aversion.” In several experiments, they found that people often refuse to choose a more efficient solution or route if it requir

The Inca were a pre-Columbian civilization whose empire sprawled along South America’s Pacific Coast from the 15th to the 16th century CE. Like other Andean peoples, they used khipus (also known as quipus), an intricate cord and knot system used to record information. According to Spanish colonial-era sources, only male Inca elites could make khipus. A new study, however, challenges this widespread notion.

This quantum radar could image buried objects

technologyreview.com Sophia Chen 2025-11-30 14:00:00

The glass cell that serves as the radar’s quantum component is full of cesium atoms kept at room temperature. The researchers use lasers to get each individual cesium atom to swell to nearly the size of a bacterium, about 10,000 times bigger than the usual size. Atoms in this bloated condition are called Rydberg atoms. When incoming radio waves hit Rydberg atoms, they disturb the distribution of electrons around their nuclei.
