A simplified brain model captures how slow potassium changes influence fast electrical activity, retaining ion exchange without modeling every neuron in full detail. @elife medicalxpress.com/news/2026-…

Making virtual brain models more biologically realistic by capturing ion exchange

Mean-field models are a powerful tool for understanding collective brain activity. A new model extends this approach by incorporating the exchange of ions between neurons and their surroundings,...

Shoe-wearers had more spongy bone at the back of a key ankle bone, while habitually barefoot people had more at the front—a contrast that could help interpret how human ancestors walked. phys.org/news/2026-10-bones-…

How shoes change our bones—and what that tells us about the evolution of walking

We tend to think of our bones as solid, unchanging support structures inside our bodies, but a recent study from the University of Chicago shows just how much they can change depending on how we use...

AI interrogators missed every AI respondent in 49 reverse Turing tests when the respondents received structured prompts to act human. techxplore.com/news/2026-10-…

AIs fail to reliably detect AIs in reverse Turing tests

The famous "Turing test" of computer science comes from a 1950 paper written by the British computer scientist (and war hero) Alan Turing. There are many variants, but perhaps the most common...

Stronger responses in specific amygdala neurons predicted which new images people would remember later that day, extending the region’s memory role beyond strongly emotional experiences. @NatureNeuro medicalxpress.com/news/2026-…

Amygdala activity predicts which new images may become lasting memories

A walnut-sized area of the brain known as the amygdala plays a giant role in determining which experiences end up in long-term memory and which are forgotten. The Cedars-Sinai Health Sciences...

A lizard tail preserved in amber offers direct evidence of voluntary tail-shedding 99 million years ago, though what triggered the defense remains unknown. phys.org/news/2026-10-lizard…

Lizard tail preserved in amber sheds light on a 100-million-year-old defense mechanism

A lizard making a dramatic escape, leaving its tail wriggling behind as it darts to safety, is an image familiar to many. Tail-shedding is one of the most widespread defenses against predators among...

Metal–organic gate electrodes switched current in three different semiconductors, matching a platinum gate in a direct comparison—but lower-power operation remains a research goal. @advmater techxplore.com/news/2026-10-…

Tunable gate electrodes could help semiconductors operate at lower voltages

Smartphones and computers process information by switching the current that flows inside semiconductors on and off. The gate electrode delivers the signal that controls this switching. Until now,...
