Scientists have identified a weakened brain signal that may connect several seemingly unrelated symptoms of schizophrenia, including sensory processing difficulties, disorganized speech, and greater symptom severity. The surprising discovery could help explain the disorder's underlying mechanisms and potentially lead to earlier detection and new treatments.

A study of nearly 13,000 adults found that people consuming the most artificial sweeteners experienced a 62% faster decline in memory and thinking skills, equivalent to approximately 1.6 additional years of brain aging. Six popular sweeteners were linked to faster cognitive decline, raising concerns about the long-term brain health effects of common sugar su

Using statistical techniques, a new study has arrived at a harrowing estimate: Three of four retired pro football players most likely had C.T.E. at death.

Finlay O'Neill thought his sporting days were over when his dislocated a knee at the age of 16. Now he is preparing to play a part in England's bid to retain the Wheelchair Rugby League World Cup.

A major new study reveals that autistic children’s brains process faces differently, and those differences may begin earlier than scientists previously thought. Researchers found that brain signals associated with recognizing faces become more specialized as neurotypical children grow older, but show much less change in autistic children. The discovery could

<p>ARTIFICIAL intelligence is usually presented as weightless, almost entirely digital. We ask it to write, calculate, translate or create an image, and the response appears instantly.

More householders are disconnecting from the gas network or moving into homes without piped gas. But a rule change could mean higher gas bills for those who are stuck with gas.

Why do some people stay mentally sharp even when their brains show signs of Alzheimer’s disease? Scientists in the Netherlands may have uncovered an important clue hidden in a rare group of immature brain cells. Researchers discovered that these cells remain present even in people over 80, but their behavior differs dramatically between those who develop dem

The controversial discovery that our brains can generate new neurons surprisingly late in life is now prompting a rethink of adult brain health, pointing the way to better treatments for stroke, dementia and depression

Scientists have filmed tiny magnetic vortices called skyrmions melting out of an organized lattice for the first time, revealing new ways to manipulate these unusual structures. The breakthrough could help make brain-like computers a reality, potentially enabling dramatically smaller and more energy-efficient technology.

We now know that cells exchanged during pregnancy can take up residency in our brain. Could they influence our development, health or even behaviour? Columnist Helen Thomson explores this mysterious cellular legacy

Scientists have uncovered a surprising new clue to why the Mediterranean diet is so good for the heart, brain, and healthy aging. Researchers at USC found that older adults who closely followed the diet had higher levels of two tiny proteins, humanin and SHMOOSE, produced by the mitochondria, the energy-producing structures inside cells. These proteins have

Scientists discovered that the thick, sticky fluid surrounding glioblastoma tumors can make brain cancer cells smaller, more flexible, and better at invading surrounding tissue. Even more troubling, some of these changes persist after the cells leave the thick fluid, revealing a previously overlooked mechanism that could help this deadly cancer spread.

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.
