Scientists just found cancer cells’ hidden power source

When cancer cells are physically squeezed, they mount an instant, high-energy defense by rushing mitochondria to the cell nucleus, unleashing a surge of ATP that fuels DNA repair and survival. This newly discovered mechanism, visualized in real time with advanced microscopy, shows mitochondria acting like emergency first responders rather than static power plants. The structures, called NAMs, were also identified in patient tumor biopsies, suggesting real-world relevance to cancer’s spread.

Scientists discover hidden protein that switches off hunger

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 eating” signals. The discovery offers new hope for tackling obesity by targeting this natural hunger switch.

Hidden cellular “power switch” could transform Parkinson’s treatment

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 regulator improved symptoms and mitochondrial health. The findings could inspire new drugs for Parkinson’s, mitochondrial disorders, and even cancer.

The vitamin D mistake weakening your immunity

Scientists discovered that vitamin D2 supplements can lower levels of vitamin D3, the form the body uses most effectively. Unlike D2, vitamin D3 enhances the immune system’s first line of defense against infections. This raises questions about which type of supplement should be prioritized.

This “chaos enzyme” may hold the key to stopping cancer spread

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. Blocking EZH2 restored stability and prevented cancer cells from traveling to distant organs. This discovery opens the door to new therapies that may finally tame this aggressive disease.

Surprising study reveals what really kills fatty liver disease patients

Metabolic dysfunction-associated steatotic liver disease (MASLD) affects over a third of the global population and is linked to serious health problems. A new study has revealed that high blood pressure, diabetes, and low HDL cholesterol are the deadliest cardiometabolic risk factors for patients with MASLD, with high blood pressure proving to be even riskier than diabetes. The findings also show that obesity and body mass index significantly influence mortality, and that each additional risk factor compounds the danger.

The invisible chemical in the air that could be raising Parkinson’s risk

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 million people, finding that those living in areas with the highest outdoor TCE levels faced a 10% greater risk of developing Parkinson’s.

Scientists just cracked the mystery of why cancer immunotherapy fails

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, TexPSR accelerates protein production, flooding the cells with toxic buildup. Blocking it restored T-cell function and improved cancer immunotherapy.

A flu test you can chew

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 alternative to nasal swabs. Unlike current tests that are slow, costly, or miss early infections, this method could catch the flu before symptoms appear.

Millions could be living with hidden smell loss after COVID without knowing

A massive NIH-backed study reveals that COVID-19’s toll on smell may be more widespread and lasting than most realize. Even patients without noticeable symptoms often performed poorly on scent tests, raising safety and health concerns. Because smell loss can signal deeper neurological issues, experts are calling for routine testing and exploring new treatments.

How gaslighting tricks the brain into questioning reality

Gaslighting, often seen as a form of manipulation, has now been reframed by researchers at McGill University and the University of Toronto as a learning process rooted in how our brains handle prediction and surprise. Instead of merely being explained through outdated psychodynamic theories, this new model highlights how trust and close relationships can be exploited by manipulators who repeatedly undermine a person’s confidence in their own reality.

DOLPHIN AI uncovers hundreds of invisible cancer markers

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 cells to simulate disease and drug responses.

Blocking one protein supercharges the immune system against cancer

Scientists have found a way to supercharge the immune system’s T cells by blocking a protein called Ant2, essentially rewiring how these cells generate energy. This metabolic reprogramming makes them more resilient, faster, and deadlier against tumors.

A plant compound might be the secret weapon against gum disease

A team of researchers tested morin, a plant compound, against gum disease bacteria and found strong antimicrobial benefits. By encapsulating it in polymers, they created a powdered form for oral hygiene products. This could replace antibiotics, avoid side effects from existing treatments, and help vulnerable patients maintain oral health.
