A cat named Pepper has once again helped scientists discover a new virus—this time a mysterious orthoreovirus found in a shrew. Researchers from the University of Florida, including virologist John Lednicky, identified this strain during unrelated ...
A surprising new study has uncovered over 200 misfolded proteins in the brains of aging rats with cognitive decline, beyond the infamous amyloid and tau plaques long blamed for Alzheimer’s. These shape-shifting proteins don’t clump into visible ...
Adopting a physically active lifestyle at any stage of adulthood significantly lowers your risk of dying from any cause, especially from cardiovascular disease. A sweeping analysis of 85 studies confirms that those who stay active consistently ...
Scientists at ETH Zurich have broken new ground by generating over 400 types of nerve cells from stem cells in the lab, far surpassing previous efforts that produced only a few dozen. By ...
A team of researchers has discovered that a protein called cypin plays a powerful role in helping brain cells connect and communicate, which is crucial for learning and memory. By uncovering how ...
A team at Scripps Research has created a microchip that can rapidly reveal how a person's antibodies respond to viruses using only a drop of blood. This game-changing technology, called mEM, ...
Scientists have uncovered DNA from 214 ancient pathogens in prehistoric humans, including the oldest known evidence of plague. The findings show zoonotic diseases began spreading around 6,500 years ...
Artificial intelligence is now designing custom proteins in seconds—a process that once took years—paving the way for cures to diseases like cancer and antibiotic-resistant infections. Australian scientists have joined this biomedical frontier ...
What if your brain is the reason some pain feels unbearable? Scientists at the Salk Institute have discovered a hidden brain circuit that gives pain its emotional punch—essentially transforming ordinary discomfort into lasting misery. This ...
MIT engineers have developed a tiny implantable device that could revolutionize emergency treatment for people with Type 1 diabetes. The device contains a powdered form of glucagon and can be remotely triggered—either manually or automatically by ...
Midlife sleep habits may matter more than previously thought. A large study finds that poor sleep, alongside high blood pressure and nicotine use, sharply increases the risk of heart problems in menopausal women yet only 1 in 5 score well on overall ...
Scientists at UCSF combined advanced brain-network modeling, genetics, and imaging to reveal how tau protein travels through neural highways and how certain genes either accelerate its toxic journey or shield brain regions from damage. Their ...

Stanford researchers discovered that dialing down an overactive enzyme, LRRK2, can regrow lost cellular “antennae” in key brain cells, restoring vital dopamine communication and neuroprotective ...

Breathing polluted air—even at levels considered “safe”—may quietly damage your heart. A new study using advanced MRI scans found that people exposed to more air pollution showed early signs ...

A new brain scan tool shows how quickly your body and mind are aging. It can spot early signs of diseases like dementia, long before symptoms begin. The scan looks at hidden clues in your brain to ...

Locked-down Hungarians who gained or lost pets saw almost no lasting shift in mood or loneliness, and new dog owners actually felt less calm and satisfied over time—hinting that the storied “pet ...

Cambridge scientists have spotted gut bacteria that greedily soak up PFAS “forever chemicals,” then ferry them safely out of the body in animal tests, removing up to three-quarters of the toxins ...

Researchers testing urine from 2- to 4-year-olds in four U.S. states uncovered 96 different chemicals, many of them unmonitored and linked to hormone and brain disruption. Legacy toxins like ...

Illinois engineers fused ultrafast imaging with smart algorithms to peek at living brain chemistry, turning routine MRIs into metabolic microscopes. The system distinguishes healthy regions, grades ...

Over a thousand students revealed a striking link between lactose intolerance and nightmare-filled nights, hinting that midnight stomach turmoil from dairy can invade dreams. Researchers suggest ...

Teen vaping is changing fast — and not in a good way. A large national study found that more adolescents are vaping THC, CBD, and especially synthetic cannabinoids, which are often unregulated and ...
