A massive Swedish study tracking nearly 28,000 people for 25 years found an unexpected link between full-fat dairy and brain health. Among adults without a genetic risk for Alzheimer’s, eating more full-fat cheese was associated with a noticeably ...
Scientists still don’t know how the brain turns physical activity into thoughts, feelings, and awareness—but a powerful new tool may help crack the mystery. Researchers at MIT are exploring transcranial focused ultrasound, a noninvasive ...
When the brain rests, it usually replays recent experiences to strengthen memory. Scientists found that in Alzheimer’s-like mice, this replay still occurs — but the signals are jumbled and poorly coordinated. As a result, memory-supporting brain ...
Middle age is becoming a tougher chapter for many Americans, especially those born in the 1960s and early 1970s. Compared with earlier generations, they report more loneliness and depression, along with weaker physical strength and declining memory. ...
Scientists warn that rapid advances in AI and neurotechnology are outpacing our understanding of consciousness, creating serious ethical risks. New research argues that developing scientific tests ...
Scientists in Sweden and Norway have uncovered a promising way to spot Parkinson’s disease years—possibly decades—before its most damaging symptoms appear. By detecting subtle biological signals in the blood tied to how cells handle stress and ...
A massive international study of more than 3,100 long COVID patients uncovered a striking divide in how brain-related symptoms are reported around the world. In the U.S., the vast majority of non-hospitalized patients described brain fog, ...
Where your body stores fat may matter just as much as how much you carry—especially for your brain. Using advanced MRI scans and data from nearly 26,000 people, researchers identified two surprising fat patterns tied to faster brain aging, ...
AI may learn better when it’s allowed to talk to itself. Researchers showed that internal “mumbling,” combined with short-term memory, helps AI adapt to new tasks, switch goals, and handle complex challenges more easily. This approach boosts ...
A common parasite long thought to lie dormant is actually much more active and complex. Researchers found that Toxoplasma gondii cysts contain multiple parasite subtypes, not just one sleeping form. Some are primed to reactivate and cause disease, ...
Findings could create new opportunities to treat and study neurodegenerative diseasesScientists discovered that sugar metabolism plays a surprising role in whether injured neurons collapse or cling to life. By activating internal protective ...
A new genetic study suggests that obesity and high blood pressure may play a direct role in causing dementia, not just increasing the risk. By analyzing data from large populations in Denmark and the U.K., researchers found strong evidence that ...

Researchers have identified a key molecular interaction that accelerates Parkinson’s disease by damaging the brain’s energy systems. They designed a new treatment that intercepts this harmful ...

Cannabis-based medicines have been widely promoted as a potential answer for people living with chronic nerve pain—but a major new review finds the evidence just isn’t there yet. After analyzing ...

Scientists have discovered that the adolescent brain does more than prune old connections. During the teen years, it actively builds dense new clusters of synapses in specific parts of neurons. These ...

Researchers report that vagus nerve stimulation helped many people with long-standing, treatment-resistant depression feel better—and stay better—for at least two years. Most participants had ...

A massive international brain study has revealed that memory decline with age isn’t driven by a single brain region or gene, but by widespread structural changes across the brain that build up over ...

A new study reveals that alpha brain waves help the brain decide what belongs to your body. Faster rhythms allow the brain to match sight and touch more precisely, strengthening the feeling that a ...

Despite longstanding guidelines, many dementia patients are still prescribed brain-altering medications that can raise the risk of falls and confusion. A new study shows that while prescribing has ...

Researchers have identified OTULIN, an immune-regulating enzyme, as a key trigger of tau buildup in the brain. When OTULIN was disabled, tau vanished from neurons and brain cells remained healthy. ...

A large genetic screen has revealed how stem cells transform into brain cells, exposing hundreds of genes that make this process possible. Among the discoveries is PEDS1, a gene now linked to a ...

New research shows gut bacteria can directly influence how the brain develops and functions. When scientists transferred microbes from different primates into mice, the animals’ brains began to ...

The brain constantly blends split-second reactions with slower, more thoughtful processing, and new research shows how it pulls this off. Scientists discovered that brain regions operate on different ...

A new study suggests the vagus nerve may be one of the heart’s most important defenders against aging. Researchers found that keeping this nerve connected to the heart helps protect heart cells and ...

ADHD stimulants appear to work less by sharpening focus and more by waking up the brain. Brain scans revealed that these medications activate reward and alertness systems, helping children stay ...

Researchers have created a protein that can detect the faint chemical signals neurons receive from other brain cells. By tracking glutamate in real time, scientists can finally see how neurons ...

Alzheimer’s has long been considered irreversible, but new research challenges that assumption. Scientists discovered that severe drops in the brain’s energy supply help drive the disease—and ...

Attention depends on the brain’s ability to filter out distractions, but new research suggests this works best when background brain activity is quieter. Scientists found that lowering certain ...

A new study suggests that dementia may be driven in part by faulty blood flow in the brain. Researchers found that losing a key lipid causes blood vessels to become overactive, disrupting circulation ...

The familiar fight between “mind as software” and “mind as biology” may be a false choice. This work proposes biological computationalism: the idea that brains compute, but not in the ...

Cannabis products with higher THC levels may slightly reduce chronic pain, particularly nerve pain, according to a review of multiple clinical trials. The improvement was small and short-lived, while ...

A new study suggests temporal lobe epilepsy may be linked to early aging of certain brain cells. When researchers removed these aging cells in mice, seizures dropped, memory improved, and some ...
