Long before humans built cities or wrote words, our ancestors may have faced a hidden threat that shaped who we became. Scientists studying ancient teeth found that early humans, great apes, and even Neanderthals were exposed to lead millions of ...
Johns Hopkins scientists uncovered microscopic “nanotube” channels that neurons use to transfer toxic molecules. While this process clears waste, it can also spread harmful proteins like amyloid-beta. Alzheimer’s-model mice showed more ...
Scientists discovered that lean pork builds muscle more effectively post-workout than high-fat pork, even with identical protein levels. Using advanced tracking techniques, they found that fat content blunted the body’s muscle-building response. ...
Korean researchers found that low-dose radiation therapy eased knee pain and improved movement in people with mild to moderate osteoarthritis. The treatment, far weaker than cancer radiation, showed real benefits beyond placebo. With no side effects ...
A new human liver organoid microarray developed by Cincinnati Children’s and Roche recreates immune-driven liver injury in the lab. Built from patient-derived stem cells and immune cells, it accurately models how genetics influence drug reactions. ...
Researchers have synthesized enhanced vitamin K analogues that outperform natural vitamin K in promoting neuron growth. The new compounds, which combine vitamin K with retinoic acid, activate the mGluR1 receptor to drive neurogenesis. They also ...
Researchers at USC have created the first method to noninvasively measure microscopic blood vessel pulses in the human brain. Using advanced 7T MRI, they found these tiny pulsations grow stronger with age and vascular risk, disrupting the brain’s ...
Scientists at UC Irvine have found a way to potentially reverse age-related vision loss by targeting the ELOVL2 “aging gene” and restoring vital fatty acids in the retina. Their experiments in mice show that supplementing with specific ...
Groundbreaking Harvard research is exposing hidden energy failures inside brain cells that may drive major psychiatric conditions. By studying reprogrammed neurons, scientists are revealing how cellular metabolism shapes mood, thought, and ...
Scientists at Mass General Brigham have created HPV-DeepSeek, a blood test that can detect HPV-linked head and neck cancers nearly a decade before diagnosis. By finding viral DNA in the bloodstream, the test achieved 99% sensitivity and specificity. ...
A team at Massachusetts General Hospital uncovered that an immune defense protein, Resistin-like molecule gamma, attacks heart cells after a heart attack—literally punching holes in them. This discovery explains why dangerous, fast heart rhythms ...
Finasteride, a common hair-loss drug, has long been tied to depression and suicide, but regulators ignored the warnings. Prof. Mayer Brezis’s review exposes global data showing psychiatric harm and a pattern of inaction by Merck and the FDA. ...

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 ...

MIT and Harvard scientists have designed an advanced type of immune cell called a CAR-NK cell that can destroy cancer while avoiding attack from the body’s own immune defenses. This innovation ...

Men’s heavy drinking is fueling a hidden crisis affecting millions of women and children worldwide. The harms, from violence to financial instability, are especially severe where gender inequality ...

Researchers discovered that stevioside, a compound from the Stevia plant, enhances the skin absorption of minoxidil, the main treatment for pattern baldness. In mice, a stevioside-infused patch ...

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 ...

A new study shows glioblastoma isn’t confined to the brain—it erodes the skull and hijacks the immune system within skull marrow. The cancer opens channels that let inflammatory cells enter the ...

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 ...

A Weill Cornell Medicine team has found that triple-negative breast cancer depends on the enzyme EZH2 to spread. By silencing key genes, EZH2 drives chaotic cell divisions and fuels metastasis. ...

New research from Houston Methodist reveals how obesity may directly drive Alzheimer’s disease. Scientists discovered that tiny messengers released by fat tissue, called extracellular vesicles, can ...

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 ...

A surprising link between Alzheimer’s and cancer reveals that amyloid beta, a harmful protein in the brain, actually empowers the immune system. It strengthens T-cells’ energy production, helping ...

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 ...

A massive nationwide study has linked long-term exposure to the industrial chemical trichloroethylene (TCE) with a higher risk of Parkinson’s disease in older adults. Researchers examined over 1.1 ...

Ohio State researchers have discovered that exhausted T cells collapse under the weight of misfolded proteins, activating a destructive stress response called TexPSR. Unlike normal stress systems, ...

Flu detection could soon be as simple as chewing gum. Scientists have created a molecular sensor that releases a thyme-like flavor when it encounters influenza, offering a low-tech, taste-based ...

A new AI tool called DOLPHIN exposes hidden genetic markers inside single cells, enabling earlier detection and more precise treatment choices. It also sets the stage for building virtual models of ...

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 ...

Researchers have uncovered how a protein called MRAP2 acts as a key regulator of hunger. It helps move the appetite receptor MC4R to the cell’s surface, allowing it to send stronger “stop ...
