Your Epigenetic Age Is Aging Your Brain, but Not in the Way Scientists Expected

A man covering his eyes in embarassment

Inside every cell in your body, a chemical clock is running. Not ticking exactly, more like drifting: patterns of methyl groups latching onto DNA, accumulating and shifting in ways that reflect everything you’ve done, breathed, eaten, and been exposed to across a lifetime. Researchers have spent the better part of two decades trying to read … Read more

Alzheimer’s Drugs Clear the Plaques but Leave Patients No Better Off

Drugs that target amyloid beta proteins in the brain likely have no clinically meaningful positive effects, while increasing the risk of bleeding and swelling in the brain, a new Cochrane review has found.

The brain scans look unambiguous. After 18 months of treatment, the amyloid plaques that riddle the brains of early Alzheimer’s patients are visibly reduced, sometimes dramatically so. The drug is doing exactly what it was designed to do: hunting down those sticky protein deposits and clearing them away. So why aren’t the patients getting better? … Read more

AI Disclosure Labels Reduce Trust in True Science Posts While Boosting False Ones

big yellow ai warning sign

Slapping a label on AI-generated content is the regulatory world’s current favourite answer to the misinformation problem. Transparent, scalable, required by law in China and under the EU AI Act, endorsed by Meta and X. The logic seems obvious enough: tell people a machine wrote something and they’ll scrutinise it harder. They didn’t, as it … Read more

Shrunken AI Models Reveal How the Brain’s Visual Neurons Actually Work

ML technique "prunes" the model, to make it more compact.

Somewhere in the visual cortex of a macaque monkey, a single neuron fires every time a small dot appears in the right location. Not a circle, not a line — a dot, specifically, at a specific size. For decades, neuroscientists could describe this selectivity without really explaining it. Now, for the first time, they can … Read more
