A small group of people experience no pleasure from music despite normal hearing and intact emotions. Brain imaging reveals that their auditory and reward systems fail to properly communicate, leaving music emotionally flat. Researchers developed a questionnaire to measure how rewarding music feels across emotions, mood, movement, and social connection. The findings suggest pleasure isn’t all-or-nothing and may depend on how specific brain networks connect. Read more ›

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. It also sets the stage for even more comprehensive livestock genomes... Read more ›

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 users. Read more ›

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 work together could prevent serious, life-threatening events. Read more ›

Scientists at Fermilab’s MicroBooNE experiment have ruled out the existence of the elusive sterile neutrino, a particle proposed for decades to explain puzzling neutrino behavior. Their high-precision measurements showed neutrinos behaving exactly as expected—without any sign of a hidden fourth type. While this closes off a popular theory, it marks a turning point for the field, pushing researchers toward new ideas and more powerful experiments. The result also lays critical... Read more ›

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. Read more ›

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 shape brain development and disease. Read more ›

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. Read more ›

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 why the universe keeps speeding up. Read more ›

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 slowed tumor growth and sparked strong anticancer immune responses. Read more ›

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 as key defenses against infection.

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 could speed up how new crops are adapted for a... Read more ›

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 after. Read more ›

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-forming gas at a staggering rate. Read more ›

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 continents. The discovery could help scientists track the... Read more ›

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 that were previously impossible.

Crystals hidden in Australia’s oldest rocks have revealed new clues about how Earth and the Moon formed. The study suggests Earth’s continents didn’t begin growing until hundreds of millions of years after the planet itself formed. When scientists compared the rocks with Moon samples from the Apollo missions, they found a remarkable match. The results support the idea that a massive cosmic impact gave birth to the Moon.

Although the gut renews itself constantly, its stem cells accumulate age-related molecular changes that quietly alter how genes are switched on and off. Scientists found that this “epigenetic drift” follows a clear pattern and appears in both aging intestines and most colon cancers. Some regions age faster than others, forming a patchwork of weakened tissue more prone to degeneration. Encouragingly, researchers showed this drift can be slowed—and partly reversed—by restoring...

Sleep isn’t just about feeling rested—it may be one of the strongest predictors of how long you live. Researchers analyzing nationwide data found that insufficient sleep was more closely tied to shorter life expectancy than diet, exercise, or loneliness. The connection was consistent year after year and across most U.S. states. The takeaway is simple but powerful: getting seven to nine hours of sleep may be one of the best... Read more ›

New research shows that aging blood can accelerate Alzheimer’s-like changes in the brain, while younger blood may offer protection. In mouse experiments, older blood worsened memory performance and increased toxic protein buildup linked to the disease. The study also uncovered widespread changes in brain proteins tied to communication and signaling. The findings point to the blood as a powerful influencer of brain health—and a promising new therapeutic target. Read more ›
