Scientists have peered inside the skull of a 380-million-year-old Antarctic fish that was closely related to the first animals to walk on land, revealing surprising clues about how life began its move out of the water. Using advanced neutron imaging, researchers discovered that Koharalepis jarviki had features suited for living near the water’s surface, including openings in its skull that may ha…

Deep inside 100-million-year-old amber from Myanmar, scientists uncovered a bizarre ancient bug with clawed front legs that look more like a crab’s pincers than anything seen in modern insects. The discovery is so unusual that researchers say these crab-like “chelae” evolved independently in this lineage, making it only the fourth known example of such structures appearing in insects at all.

New NIH research reveals that semaglutide sparks different responses inside appetite-controlling brain cells, offering fresh insight into why GLP-1 weight-loss drugs don’t work the same for everyone. Scientists also found a possible way to extend the drugs’ effects, potentially helping patients push past weight-loss plateaus.

Generative AI is transforming the workplace faster than ever, but new research from the University of Vaasa suggests the biggest threat may not be AI itself — it’s falling behind in learning how to use it. Researcher Zhe Zhu found that employees who see tools like ChatGPT and Gemini as helpful collaborators rather than job-stealing rivals tend to be more engaged, adaptable, and optimistic about t…

A massive international study could upend 40 years of heart attack treatment. Researchers found that beta blockers—routinely prescribed after uncomplicated heart attacks—offered no real benefit for patients whose heart function remained normal, despite being given to millions worldwide. Even more surprising, women taking the drugs faced a higher risk of death, repeat heart attack, or hospitalizat…

Scientists have uncovered a surprising twist in how cells behave when division goes wrong. Sometimes a cell successfully copies its DNA but fails to split into two, leaving it with double the genetic material — a mistake linked to aging, cancer, and other major diseases. Researchers discovered that not all of these failures are equal.

A mysterious little blue octopus discovered nearly 6,000 feet beneath the waters of the Galápagos Islands has officially been identified as a brand-new species. About the size of a golf ball, the tiny creature stunned researchers during a deep-sea expedition when it suddenly appeared on camera, crawling across the ocean floor near an underwater mountain.

Drinking nitrate-rich beetroot juice may do more than support heart health — it could actually reshape the bacteria living in the mouth in ways that help lower blood pressure in older adults. In the largest study of its kind, researchers found that older people who drank concentrated beetroot juice twice daily for two weeks experienced noticeable blood pressure reductions, while younger adults di…

Scientists at UT Southwestern have uncovered a surprising new “master switch” that helps control how much cholesterol the liver sends into the bloodstream. The newly identified protein, HELZ2, works by shutting down the genetic instructions needed to produce apoB — a key building block of the cholesterol-carrying particles linked to clogged arteries and heart disease.

Scientists at McGill University have found a way to supercharge the immune system’s natural killer (NK) cells, helping them break through the defenses tumors use to stay alive. By temporarily blocking two proteins, researchers turned these cells into far more effective cancer fighters against difficult cancers like leukemia, glioblastoma, kidney cancer, and triple-negative breast cancer.

Researchers found that adding bananas to berry smoothies can dramatically reduce the body’s ability to absorb healthy flavanols. The surprising discovery shows that even simple food combinations can change how much nutrition your body actually gets.

For millions battling chronic nerve pain, even the softest touch can feel agonizing — but scientists may have uncovered a radically new way to stop it at the source. Researchers at Duke University found that damaged nerves can be revived by supplying them with healthy mitochondria, the tiny energy producers inside cells.

Scientists have cracked open the “black box” of feline cancer in a landmark study that genetically analyzed nearly 500 cat tumors from around the world. The research uncovered striking similarities between cancers in cats, dogs, and humans — including shared cancer-driving genes tied to aggressive breast cancers.

Scientists have uncovered the oldest known hand-held wooden tools ever used by humans — and they’re an astonishing 430,000 years old. Buried for hundreds of thousands of years at an ancient lakeside site in Greece, the carefully carved wooden objects reveal that early humans were far more skilled and resourceful than once believed.

By analyzing over 400,000 Reddit posts, researchers discovered that users of popular GLP-1 weight-loss drugs frequently discussed unexpected symptoms like menstrual irregularities, chills, and hot flashes. The findings suggest AI could turn social media into a powerful early-warning system for spotting side effects that clinical trials may miss.
