- newMajor trial challenges how doctors decide who really needs statins
A study of nearly 5,800 adults found that heart scans measuring calcium buildup in the arteries led to the same observed rate of major cardiovascular events as traditional risk assessments, despite recommending statins to far fewer patients. Surprisingly, patients advised to take statins based on their scans were nearly three times as likely to stick with their medication, raising intriguing questions about how doctors should identify and treat heart disease risk.

- newFor decades, we were told to avoid full-fat dairy. New research says otherwise
Full-fat dairy may not be the health villain it has long been portrayed as, according to a new study finding that three daily servings did not worsen weight, cholesterol, or insulin resistance over 12 weeks. Researchers also observed improvements in blood pressure and nutrient intake, raising questions about longstanding recommendations to choose low-fat dairy.

- newAn anti-aging drug may help protect the brain before Alzheimer's symptoms begin
A surprising new study suggests that an anti-aging drug could help protect people genetically predisposed to Alzheimer's disease. Researchers found that just four weeks of low-dose rapamycin improved brain blood flow in healthy middle-aged adults carrying the high-risk APOE4 gene variant, with women showing the strongest benefits. Because declining blood flow can occur years before Alzheimer's symptoms appear, the discovery raises hopes for preventing or delaying the disease before memory loss b…

- Scientists discover mysterious “lonely” brain waves linked to memory loss
Scientists have uncovered a surprising link between Alzheimer’s-related protein buildup, disrupted brain waves during deep sleep, and fading memory. The findings suggest that hidden changes in how the brain processes memories overnight may contribute to age-related memory loss long before Alzheimer’s symptoms appear.

- Goodbye, cavities? Scientists create gel that could regrow tooth enamel
Scientists have developed a revolutionary gel that could regrow lost tooth enamel by harnessing minerals naturally found in saliva, potentially overcoming one of dentistry’s biggest limitations. The regenerated enamel behaves much like healthy enamel, raising hopes for a simple treatment that could repair damaged teeth, prevent decay, and reduce sensitivity.

- Scientists solve 30-year-old mystery and discover a hidden defense against inflammation
Scientists have solved a decades-old mystery and uncovered a hidden immune system defense that protects healthy cells from the very inflammation meant to fight infections. The surprising discovery could lead to new approaches for treating cancer, inflammatory bowel disease, and other conditions involving excessive inflammation.

- Scientists turn viruses into weapons against deadly superbugs
Scientists are advancing a promising new way to fight antibiotic-resistant infections by using viruses that specifically target and kill harmful bacteria. An international team has released the first coordinated guidelines for personalized phage therapy, offering a roadmap for safely bringing this experimental treatment into clinical practice. Early findings are encouraging, with one study reporting improvement in 77% of patients and the disappearance of targeted bacteria in 61%.

- A surprising discovery could help aging muscles repair themselves
Scientists have discovered a compound that transforms a natural muscle-repair protein into a more powerful version dubbed "Super HGF," more than doubling its ability to bind to a key receptor while protecting it from age-related chemical damage. The breakthrough, supported by early mouse experiments, could eventually help combat muscle loss and preserve strength as people age.

- Scientists may have finally explained why our brains and bodies are cross-wired
Scientists propose that the brain’s mysterious cross-wiring, which connects each hemisphere to the opposite side of the body, may have originated more than 500 million years ago in the visual systems of ancient fish. Rather than evolving for a specific advantage, this unusual arrangement may simply be a legacy of evolution building new brain circuits on an ancient foundation.

- Permanent daylight saving time has a dark side, scientists warn
A new study warns that permanent daylight saving time could force American children to make at least 2 billion additional school commutes in darkness, potentially increasing safety risks and disrupting their biological clocks. Researchers found that fatal crashes involving school-aged pedestrians were roughly twice as likely during dark mornings as after sunrise.

- AI helps Stanford scientists discover a “natural Ozempic” with a surprising advantage
Stanford researchers have discovered an AI-identified natural molecule that dramatically suppresses appetite and promotes fat loss in animals, potentially offering an Ozempic-like weight-loss treatment without common digestive side effects or significant muscle loss. Called BRP, the molecule reduced food intake by up to 50% and targets a different brain pathway, raising hopes for a more precise obesity treatment if future human trials prove successful.

- Gene editing could replace a lifetime of medication, but there's a catch
A single gene-editing treatment could someday protect against heart disease, high cholesterol, and other common conditions for decades, potentially replacing lifelong medications. But scientists warn that permanently altering genes introduces risks that could take years to emerge, making long-term safety a critical challenge.

- Scientists trick cancer cells into making the drugs that kill them
Scientists have developed a promising new cancer-fighting strategy that uses carbon monoxide naturally produced by tumor cells to manufacture powerful drugs inside the cancer cells themselves. Early laboratory experiments suggest the technique could selectively attack cancer while sparing healthy cells, potentially paving the way for safer chemotherapy alternatives.

- Kids who eat more ultra-processed foods show a troubling brain response
A new study suggests that ultra-processed foods may influence children's developing brains in ways that encourage weight gain. Researchers from USC studied 46 children ages 7 to 10 and found that those who ate more ultra-processed foods showed stronger activity in the brain's reward system when viewing tempting foods like cookies and French fries. These heightened brain responses were linked to greater increases in body fat and body mass index (BMI) one year later, suggesting that the brain's se…

- The brain’s hidden fear mechanism may explain anxiety and PTSD
A surprising new discovery suggests that fear may cause the brain to blur the line between danger and safety rather than distinguish them more clearly. By observing brain activity in mice using augmented reality, scientists found that memories of threatening and harmless environments began to overlap, potentially allowing faster responses to danger. This "better safe than sorry" survival mechanism could help explain why people with anxiety or PTSD sometimes experience intense fear in completely…
