Researchers found that simply changing what people thought they were drinking—sugar or artificial sweetener—could dramatically shift how much they enjoyed it. When participants believed a drink had artificial sweeteners, real sugar tasted less enjoyable, but when they expected sugar, even artificially sweetened drinks became more pleasurable.

Instead of diagnoses, it’s the severity of autism-like traits that seems to shape how the brain is wired—even in children who don’t officially have autism. The study found that certain brain networks tied to thinking and social behavior stay unusually connected in kids with stronger autism symptoms, hinting at a different developmental path.

Using cutting-edge MRI scans, researchers discovered that fluid flows along the middle meningeal artery in a slow, lymphatic-like pattern—very different from blood. This confirms the presence of a previously unknown drainage hub in humans. The finding could transform how scientists approach brain aging, injury, and diseases like Alzheimer’s.

In experiments with genetically engineered mice, removing this protein led to memory loss, brain damage, and other hallmarks of Alzheimer’s, including weakened blood-brain barriers and reduced formation of new neurons. The findings suggest that this “rotten egg” gas, when carefully regulated, may actually protect brain cells and support memory.

While nearly everyone agrees that studying the autistic brain is essential, most people are unaware that brain donation after death is a key part of making that research possible. Unlike organ donation, brain donation is a separate process, and widespread confusion remains about how it works, when it must occur, and who can participate.

Researchers found that astrocytes—once thought to just support neurons—actually play a key role in controlling appetite. After a meal, glucose triggers tanycytes, which send signals to astrocytes that then activate fullness neurons. This newly discovered pathway could lead to innovative treatments for obesity and eating disorders.

Researchers found they actively help form, recall, and weaken fear responses by interacting with neurons in real time. Changing astrocyte activity directly altered how strong fear memories became. This breakthrough could lead to entirely new treatments for anxiety-related disorders.

The mutation disrupts a brain circuit involved in flexible decision-making, causing mice to stick with outdated choices even when conditions change. Researchers pinpointed the issue to a key thalamus–prefrontal cortex pathway. By reactivating this circuit, they were able to restore normal behavior—raising hope for future therapies.

Scientists have now mapped the neural circuits behind this process, uncovering a delicate feedback loop in which sleep boosts growth hormone, and that same hormone helps regulate wakefulness. Mon, 30 Mar 2026 21:39:42 EDT https://www.sciencedaily.com/releases/2026/03/260330210905.htm https://www.sciencedaily.com/releases/2026/03/260330001126.htm Just a few minutes of getting out of breath each day could dramatically cut your risk of major diseases—including heart disease, dementia, and diabetes. A large study of nearly 100,000 people found that it’s not just how much you move, but how intensely you move that matters. Short bursts of vigorous activity—like rushing for a bus or climbing stairs quickly—were linked to striking reductions in disease risk, especially for inflammatory conditions and brain health. Mon, 30 Mar 2026 01:07:46 EDT https://www.sciencedaily.com/releases/2026/03/260330001126.htm https://www.sciencedaily.com/releases/2026/03/260328043556.htm After a stroke, the brain may do something surprisingly hopeful—it can “refresh” parts of itself. Researchers analyzing brain scans from over 500 stroke survivors found that while the damaged side of the brain appears to age faster, the opposite, unaffected side can actually look younger. This unexpected shift seems to reflect the brain’s effort to rewire itself, strengthening healthy regions to compensate for lost function.

Researchers found that immersive dreaming can actually make sleep feel deeper and more refreshing, even when brain activity is high. Surprisingly, people reported their deepest sleep after intense dream experiences, not just during quiet, inactive periods. This suggests dreams may play a key role in helping us feel truly rested. Thu, 26 Mar 2026 02:00:56 EDT https://www.sciencedaily.com/releases/2026/03/260326011458.htm https://www.sciencedaily.com/releases/2026/03/260324024247.htm Scientists have found that your brain separates memories into “what” and “where/when” using two different groups of neurons. One set responds to specific objects or people, while another tracks the context or situation. When you remember something correctly, these groups briefly connect and reconstruct the full memory. This system may be the secret behind how we recognize the same things across totally different experiences. Tue, 24 Mar 2026 21:13:47 EDT https://www.sciencedaily.com/releases/2026/03/260324024247.htm https://www.sciencedaily.com/releases/2026/03/260323005526.htm Scientists have uncovered a hidden “death switch” in the brain that may be driving Alzheimer’s disease—and even found a way to turn it off in mice. The culprit is a toxic pairing of two proteins that, when combined, triggers the destruction of brain cells and fuels memory loss. By using a new compound to break apart this deadly duo, researchers were able to slow disease progression, protect brain cells, and even reduce hallmark amyloid buildup. Mon, 23 Mar 2026 05:34:10 EDT https://www.sciencedaily.com/releases/2026/03/260323005526.htm https://www.sciencedaily.com/releases/2026/03/260320073819.htm Many people believe closing their eyes sharpens hearing, but that is not always true. In noisy settings, participants struggled more to hear faint sounds with their eyes closed, while matching visuals made it easier. Researchers found that shutting the eyes leads the brain to over-filter incoming sounds. Keeping your eyes open may actually improve how well you hear in noise. Fri, 20 Mar 2026 07:49:51 EDT https://www.sciencedaily.com/releases/2026/03/260320073819.htm https://www.sciencedaily.com/releases/2026/03/260317064444.htm Early life stress may set the stage for long-term digestive problems by disrupting the gut-brain connection. Studies in both mice and thousands of children found links to symptoms like pain, constipation, and IBS. Scientists discovered that different biological pathways control different gut issues, hinting at more personalized treatments in the future. The research also highlights how a child’s early environment can have lasting physical effects—not just emotional ones.

Researchers found that people living in areas with sustained exposure had more than 2.5 times the likelihood of developing the disorder. Lab experiments reinforced the finding: animals exposed to the chemical developed movement problems, lost dopamine-producing neurons, and showed the same toxic protein buildup seen in Parkinson’s patients. Mon, 16 Mar 2026 18:49:45 EDT https://www.sciencedaily.com/releases/2026/03/260315225125.htm https://www.sciencedaily.com/releases/2026/03/260311004720.htm Scientists have developed a promising new approach to treating Alzheimer’s disease by turning ordinary brain cells into powerful plaque-clearing machines. Instead of requiring frequent antibody infusions like current therapies, the experimental treatment uses genetically engineered astrocytes — abundant support cells in the brain — that are equipped with a CAR “homing device” similar to those used in cancer immunotherapy.

Researchers at Michigan State University discovered that repeated cocaine use rewires communication between the brain’s reward system and the hippocampus, the region responsible for memory. A protein called DeltaFosB builds up with continued drug use and acts like a genetic switch, altering how neurons function and strengthening the brain’s drive to seek cocaine.

The organ contains a wide variety of specialized cells and is closely linked to the animal’s nerve network, allowing it to coordinate behavior and orientation in the water. Researchers say it may function as a primitive brain-like center. The discovery suggests that centralized nervous systems might have evolved independently in different animal lineages.

Scientists discovered that tissue stiffness can trigger the production of guidance molecules through a force-sensing protein called Piezo1. This protein not only detects mechanical forces but also helps maintain the structure of brain tissue. The discovery reveals a powerful link between the brain’s physical environment and how its wiring is built.

Researchers at the University of Notre Dame now suggest that intelligence doesn’t live in one “smart” region of the brain at all. Instead, it emerges from how efficiently and flexibly the brain’s many networks communicate and coordinate with each other.

By combining laser-based imaging with machine learning, they uncovered chemical changes that spread unevenly across the brain and extend beyond amyloid plaques. Key memory regions showed major shifts in cholesterol and energy-related molecules. The findings hint that Alzheimer’s is a whole-brain metabolic disruption—not just a protein problem.

Researchers found that Chlamydia pneumoniae can invade the retina and brain, where it sparks inflammation, nerve cell death, and the buildup of amyloid-beta—the hallmark protein linked to Alzheimer’s. Higher levels of the bacterium were found in people with Alzheimer’s, especially those carrying the high-risk APOE4 gene, and were tied to more severe cognitive decline.

New research reveals that while digital-style encoding could theoretically compress information more tightly, it would demand far more mental effort from both speaker and listener. Instead, language is built around familiar words and predictable patterns that reflect our real-world experiences, allowing the brain to constantly anticipate what comes next and narrow down meaning step by step.

Early brain scans showed that gray matter changes dramatically through the teen years, and because studies stopped around age 20, scientists estimated development might wrap up in the mid-20s. But newer, massive brain-imaging research paints a different picture: key wiring and network efficiency in the brain continue evolving into the early 30s.

Using a powerful new AI-based system called SIGNET, the team uncovered cause-and-effect relationships between genes across six major brain cell types, revealing which genes are truly driving harmful changes. The most dramatic disruptions were found in excitatory neurons, where thousands of genetic interactions appear to be extensively rewired as the disease progresses.

Neuroscientists at Northwestern University have shown that dreams can actually be nudged in specific directions — and those dream tweaks may boost creativity. By playing subtle sound cues during REM sleep, researchers prompted people to dream about unsolved brain teasers they had struggled with earlier. An astonishing 75% of participants dreamed about the cued puzzles, and those puzzles were solved far more often the next day.

They found that special support cells called astrocytes—located far from the actual injury—spring into action after damage. These “lesion-remote astrocytes” send out a protein signal, CCN1, that reprograms immune cells to efficiently clean up fatty nerve debris.

Researchers found that boosting DMTF1 can restore the ability of neural stem cells to regenerate, even when age-related damage has set in. Without it, these cells struggle to renew and support memory and learning. The findings raise hopes for treatments that could slow or even reverse aspects of brain aging.

In a major 20-year study of adults 65 and older, those who completed five to six weeks of adaptive “speed of processing” training — along with a few booster sessions — were significantly less likely to develop dementia, including Alzheimer’s disease, even two decades later. Participants who received the boosted speed training had a 25% lower dementia risk compared to those who received no training, making it the only intervention in the trial to show such a lasting protective effect.

Smell, touch, sound, sight, and balance constantly influence one another, shaping how food tastes, objects feel, and even how heavy our bodies seem. Scientists now believe humans may have more than 20 distinct senses working at once. Everyday illusions and experiences reveal just how surprisingly complex perception really is.

Scientists found that this network becomes overly connected, disrupting not just movement but also thinking and other bodily functions. When researchers targeted it with non-invasive brain stimulation, patients showed much stronger symptom improvement than with conventional stimulation. The discovery could reshape how Parkinson’s is diagnosed and treated.

Brain scans revealed grey matter loss in areas tied to memory and emotional regulation, while many women reported increased anxiety, depression, and fatigue. Hormone therapy did not reverse these effects, though it may slow age-related declines in reaction speed. Researchers say menopause could represent an important turning point for brain health.

In mouse experiments, flavanol intake boosted activity, curiosity, learning, and memory—despite these compounds barely entering the bloodstream. The key appears to be sensory stimulation: the taste itself activates brain pathways linked to attention, motivation, and stress response, lighting up regions involved in arousal and memory.

Brain scans revealed distinct patterns as infants looked at pictures of animals, toys, and everyday objects, showing early category recognition. Scientists used AI to help decode these patterns, offering a rare glimpse into infant thinking. The results suggest babies begin learning and understanding far sooner than expected.

Researchers at MIT are exploring transcranial focused ultrasound, a noninvasive technology that can precisely stimulate deep regions of the brain that were previously off-limits. In a new “roadmap” paper, they explain how this method could finally let scientists test cause-and-effect in consciousness research, not just observe correlations.

Among adults without a genetic risk for Alzheimer’s, eating more full-fat cheese was associated with a noticeably lower risk of developing the disease, while higher cream intake was tied to reduced dementia risk overall. The findings challenge decades of low-fat dietary advice but come with important caveats.

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 cells lose their stability, and the animals struggle to remember where they’ve been.

New research argues that developing scientific tests for awareness could transform medicine, animal welfare, law, and AI development. But identifying consciousness in machines, brain organoids, or patients could also force society to rethink responsibility, rights, and moral boundaries. The question of what it means to be conscious has never been more urgent—or more unsettling.

In the U.S., the vast majority of non-hospitalized patients described brain fog, depression, and anxiety, while far fewer patients in countries like India and Nigeria reported the same issues. The difference doesn’t appear to be about the virus itself, but about culture, stigma, and access to mental health care.

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 learning efficiency while using far less training data. It could pave the way for more flexible, human-like AI systems.

Using advanced MRI scans and data from nearly 26,000 people, researchers identified two surprising fat patterns tied to faster brain aging, cognitive decline, and higher neurological disease risk. One involves unusually high fat buildup in the pancreas, even without much liver fat, while the other—often called “skinny fat”—affects people who don’t appear severely obese but carry excess fat relative to muscle.

Researchers found that Toxoplasma gondii cysts contain multiple parasite subtypes, not just one sleeping form. Some are primed to reactivate and cause disease, which helps explain why infections are so hard to treat. The discovery could reshape efforts to develop drugs that finally eliminate the parasite for good.
