A groundbreaking cattle genome has given researchers their clearest look yet at what makes Wagyu beef so special. By uncovering hundreds of new genes and hidden genetic variations, scientists can now pinpoint traits linked to marbling, health, and productivity with far greater accuracy. The advance could boost profits for beef producers while improving breeding outcomes across many cattle breeds.…

Most U.S. adults have risk factors tied to a little-known condition called CKM syndrome, which connects heart disease, kidney problems, diabetes, and obesity into one powerful health threat. When these issues overlap, the danger rises far more than when they occur alone. Despite low awareness, people are eager to learn how CKM is diagnosed and treated. Experts say understanding how these systems …

Weight-loss drugs like Ozempic and Wegovy are changing how Americans spend money on food. A large Cornell study found households cut grocery spending by over 5% within six months, with even bigger drops at fast-food restaurants. Snack foods and sweets saw the steepest declines, while only a few categories like yogurt and fruit rose slightly. The effects linger for at least a year among continued …

A new study warns that war in Gaza has pushed children to the edge, leaving many too hungry, weak, or traumatized to learn. Education has nearly collapsed, with years of schooling lost to conflict, hunger, and fear. Researchers say children are losing faith in the future and in basic ideas like peace and human rights. Without urgent aid, Gaza faces the risk of a lost generation.

A large genetic screen has revealed how stem cells transform into brain cells, exposing hundreds of genes that make this process possible. Among the discoveries is PEDS1, a gene now linked to a previously unknown neurodevelopmental disorder in children. When PEDS1 does not work properly, brain growth and nerve cell formation are impaired. The findings help explain how early genetic changes can sh…

A new international trial has delivered striking results for people on dialysis, showing that daily fish oil supplements can sharply reduce serious heart-related events. Patients taking fish oil had far fewer heart attacks, strokes, and cardiac deaths than those on placebo. Researchers say this is especially important because dialysis patients face extreme cardiovascular risk and few proven treat…

Roasted coffee may do more than wake you up—it could help control blood sugar. Researchers discovered several new coffee compounds that inhibit α-glucosidase, a key enzyme linked to type 2 diabetes. Some of these molecules were even more potent than a common anti-diabetic drug. The study also introduced a faster, greener way to uncover health-boosting compounds in complex foods.

The accelerating expansion of the universe is usually explained by an invisible force known as dark energy. But a new study suggests this mysterious ingredient may not be necessary after all. Using an extended version of Einstein’s gravity, researchers found that cosmic acceleration can arise naturally from a more general geometry of spacetime. The result hints at a radical new way to understand …

Scientists have unveiled a new way to capture ultra-sharp optical images without lenses or painstaking alignment. The approach uses multiple sensors to collect raw light patterns independently, then synchronizes them later using computation. This sidesteps long-standing physical limits that have held optical imaging back for decades. The result is wide-field, sub-micron resolution from distances …

KAIST researchers have developed a way to reprogram immune cells already inside tumors into cancer-killing machines. A drug injected directly into the tumor is absorbed by macrophages, prompting them to recognize and attack cancer cells while activating nearby immune defenses. This eliminates the need for lab-based cell extraction and modification. In animal models, the strategy significantly slo…

Scientists have used CRISPR to give the goldenberry a modern makeover, shrinking the plant by about a third and making it easier to farm. Goldenberries are tasty and nutritious but notoriously unruly, with bushy plants that complicate harvesting. By editing a few key genes and selectively breeding the best-tasting fruits, researchers created new varieties ready for wider cultivation. The approach…

In a striking real-world experiment, flu patients spent days indoors with healthy volunteers, but the virus never spread. Researchers found that limited coughing and well-mixed indoor air kept virus levels low, even with close contact. Age may have helped too, since middle-aged adults are less likely to catch the flu than younger people. The results highlight ventilation, air movement, and masks …

A rapid climate collapse during the Late Ordovician Mass Extinction devastated ocean life and reshuffled Earth’s ecosystems. In the aftermath, jawed vertebrates gained an unexpected edge by surviving in isolated marine refuges. Over millions of years, they diversified into many forms while competitors faded away. This ancient reset helped determine which creatures would dominate the planet ever a…

Scientists have discovered an enormous stream of super-hot gas erupting from a nearby galaxy, driven by a powerful black hole at its center. The jets stretch farther than the galaxy itself and spiral outward in a rare, never-before-seen pattern. NASA’s James Webb Space Telescope pierced through thick dust to reveal this violent outflow. The process is so intense it’s robbing the galaxy of star-fo…

Scientists have identified a brand-new species of worm living in the Great Salt Lake, marking only the third known animal group able to survive its extreme salinity. The species, named Diplolaimelloides woaabi with guidance from Indigenous elders, appears to exist only in this lake. How it got there remains a mystery, with theories ranging from ancient oceans to birds transporting it across conti…
