The world, in perspective.

A tiny region deep within the brain has surprised scientists by revealing a remarkably sophisticated communication system. Previously thought to broadcast the same chemical signal throughout the brain, this region actually sends targeted messages that help control learning, attention, and behavior, according to new research in mice.

A surprising two-year clinical trial found that fish oil supplements successfully delivered omega-3s to the brain but failed to improve memory or protect against Alzheimer's-related brain shrinkage. Researchers suspect that getting these nutrients through a healthy diet may offer benefits that supplements alone cannot provide.

Scientists have discovered why common marmosets have unusually small, smooth brains despite starting development much like other primates. The secret lies in subtle changes to brain-building cells that slow neuron production, revealing new clues about how the large, folded human brain evolved.

Sport mit Donald Trump? Darauf hat Nicko McBrain nach eigener Aussage keine Lust. Lieber würde der Drummer der legendären Rockband Iron Maiden den US-Präsidenten im Gefängnis sehen.

Marnus Labuschagne gifts South Africa his wicket with terrible shot selection.

Nicko McBrain, the long-time drummer for heavy metal band Iron Maiden, recently admitted he’d been invited to play golf with Donald Trump, but turned down the offer because of his staunch anti-MAGA beliefs — and that the president and his “bunch of cronies,” in McBrain’s words, “should be put in jail.” Like Trump, McBrain resides […]

Australia shows a needless sense of urgency at the crease on day four and it backfires spectacularly as South Africa takes firm control in Gqeberha.

The glymphatic system flushes toxins out of the brain, but this seems to be disrupted in Alzheimer's disease, and cholesterol may be involved

This question was posed as part of New Scientist’s Last Word series, in which readers give scientific answers to each other’s questions. Here’s what our readers had to say

It’s the latest in a growing wave of bets that AI companies are making on brain data.

The aging brain may be undergoing a remarkable transformation rather than simply losing its abilities, shifting its focus from remembering details to understanding the bigger picture. Scientists suggest this change could be an evolutionary adaptation that helps older adults develop wisdom and share decades of knowledge with younger generations.

Scientists have found a promising way to protect the brain from Alzheimer’s-related damage by blocking immune cells that contribute to the destruction of neurons. In mice, the treatment preserved roughly 40% more tissue in memory centers and improved memory, even without removing harmful tau protein buildup.

A discovery in tiny algae led to a Nobel Prize-winning breakthrough that allows scientists to switch brain cells on and off using light. The revolutionary technique has already helped researchers activate memories and is opening new possibilities for restoring vision and treating brain disorders.

Scientists have uncovered an unexpected culprit behind sleep loss in Alzheimer’s disease: overactive immune cells in the brain. By temporarily removing these cells, researchers restored more than two hours of sleep per day in mice, revealing a promising new target for treatment.
