From mini-brains to spider-inspired gloves and wolf apple coatings, scientists are turning eerie-sounding experiments into real innovations that could revolutionize health and sustainability. Lab-grown brain organoids may replace animal testing, ...
Researchers used supramolecular nanoparticles to repair the brain’s vascular system and reverse Alzheimer’s in mice. Instead of carrying drugs, the nanoparticles themselves triggered natural clearance of amyloid-β proteins. This restored ...
People with gum disease may have higher levels of brain white matter damage, a new study finds. Researchers observed that participants with gum disease had significantly more white matter hyperintensities, even after accounting for other risk ...
New research reveals that intelligence plays a key role in how well people process speech in noisy environments. The study compared neurotypical and neurodivergent individuals and found that cognitive ability predicted performance across all groups. ...
Researchers found that neurons can use fat, not just sugar, to power the brain. When a protein called DDHD2 fails, this process breaks down and leads to serious brain problems. Scientists were able to restore damaged cells by feeding them fatty ...
Inside your body, an intricate communication network constantly monitors breathing, heart rate, digestion, and immune function — a hidden “sixth sense” called interoception. Now, Nobel laureate ...
Cedars-Sinai researchers created “young” immune cells from human stem cells that reversed cognitive decline and Alzheimer’s symptoms in mice. The treated animals showed better memory and healthier brain structures. The cells seemed to protect ...
Scientists have uncovered a toxic alliance between Aβ and fibrinogen that may explain how Alzheimer’s disease begins. The two proteins together create stubborn clots that damage blood vessels and spark inflammation in the brain. These effects ...
New research reveals that exercise counteracts the mood-damaging effects of a Western-style diet through specific gut and hormonal mechanisms. Running restored metabolites tied to mental well-being and balanced key hormones like insulin and leptin. ...
Menopause brings profound shifts not just in hormones but in the very structure of the brain. Scientists have found that gray matter in regions tied to memory and thinking can shrink, while white matter may show damage linked to blood flow issues. ...
A major collaboration between UC San Diego and 23andMe identified genes that shape cannabis use behaviors. The study linked the CADM2 and GRM3 genes to cannabis use and connected these patterns to more than 100 traits across mental and physical ...
SuperAgers defy normal aging by keeping sharp memories and healthy brains well into their 80s. Northwestern scientists discovered that these individuals either resist the buildup of harmful brain ...

Researchers have identified two compounds, K102 and K110, that could repair the nerve damage from multiple sclerosis. These drugs help regenerate the protective myelin sheath and balance immune ...

Scientists have pinpointed Y1 receptor neurons in the brain that can override chronic pain signals when survival instincts like hunger or fear take precedence. Acting like a neural switchboard, these ...

Researchers from Leeds found that overeating is driven more by what people believe about food than by its actual ingredients or level of processing. Foods perceived as fatty, sweet, or highly ...

Stanford scientists found that aging disrupts the brain’s internal navigation system in mice, mirroring spatial memory decline in humans. Older mice struggled to recall familiar locations, while a ...

Researchers uncovered a key cellular regulator, PP2A-B55alpha, that controls both the cleanup of damaged mitochondria and the creation of new ones. In Parkinson’s disease models, reducing this ...

Penn researchers found that psilocybin can calm brain circuits tied to pain and mood, easing both physical suffering and emotional distress in animal studies. The compound works in the anterior ...

Researchers have designed a peptide that prevents the deadly misfolding of alpha-synuclein, the protein behind Parkinson’s and some dementias. In lab and animal tests, it stabilized the protein and ...

Scientists confirmed that pianists can alter timbre through touch, using advanced sensors to capture micro-movements that shape sound perception. The discovery bridges art and science, promising ...

Dolphins washing up on Florida’s shores may be victims of the same kind of brain degeneration seen in humans with Alzheimer’s disease. Researchers discovered that cyanobacterial toxins—worsened ...

Researchers in Japan have pinpointed a biological cause of Long COVID brain fog using advanced PET brain imaging. They discovered widespread increases in AMPA receptor density linked to cognitive ...

Scientists discovered that lifelong social support can slow biological aging. Using DNA-based “epigenetic clocks,” they found that people with richer, more sustained relationships showed younger ...

Boston University researchers found that ordinary moments can gain staying power if they’re connected to significant emotional events. Using studies with hundreds of participants, they showed that ...

New studies show that a bacterial molecule, peptidoglycan, is present in the brain and fluctuates with sleep patterns. This challenges the idea that sleep is solely brain-driven, instead suggesting ...

A University of New Mexico scientist is revealing what might be one of the most overlooked causes of dementia — damage in the brain’s tiny blood vessels. Dr. Elaine Bearer has created a new way ...

Researchers in Japan discovered that Parkinson’s patients diagnosed in their 80s are far more likely to show signs of amyloid buildup, a hallmark of Alzheimer’s, even without dementia symptoms. ...

For decades, scientists believed Alzheimer’s was driven mainly by sticky protein plaques and tangles in the brain. Now Purdue researchers have revealed a hidden culprit: fat. They found that brain ...

New studies reveal that lifestyle changes—such as exercise, healthy eating, and social engagement—can help slow or prevent cognitive decline. Experts say this low-cost, powerful approach could ...

Scientists in Zurich have shown that stem cell transplants can reverse stroke damage by regenerating neurons, restoring motor functions, and even repairing blood vessels. The breakthrough not only ...

Scientists have uncovered how the brain reroutes its communication pathways depending on whether it’s processing something new or recalling the familiar. By fine-tuning the balance between ...

Addiction often isn’t about chasing pleasure—it’s about escaping pain. Researchers at Scripps Research have discovered that a tiny brain region called the paraventricular nucleus of the ...
