A large study found that women taking GLP-1 drugs, the medication class behind Ozempic, Wegovy, Mounjaro, and Zepbound, were about 30% less likely to develop breast cancer. Researchers say the findings are promising but not yet proof, and clinical trials are now being planned to test whether these drugs could help prevent breast cancer. Read more ›

Scientists have uncovered a surprising secret about our DNA: it’s not a static blueprint, but a constantly shifting, folding structure that helps control how genes turn on and off. Researchers at the Salk Institute found that different parts of the genome loop and unloop at different speeds, with more active regions constantly reshaping themselves to support gene activity.

A new shape-shifting material can change both its texture and color in seconds, inspired by the camouflage abilities of octopuses. By precisely controlling how a polymer swells with water, researchers can create detailed, reversible patterns at the nanoscale. The material can even mimic realistic surfaces and dynamically adjust how it reflects light. In the future, AI could allow it to automatically blend into its surroundings. Read more ›

Scientists have taken lasers beyond light and into the realm of sound, creating a breakthrough “phonon laser” that manipulates tiny vibrations at the quantum level. By dramatically reducing noise in these systems, researchers can now measure motion and forces with unprecedented precision. This advance could unlock new ways to study gravity, probe quantum physics, and even revolutionize navigation with ultra-accurate, satellite-free systems. Read more ›

Perovskite crystals can dramatically and reversibly change shape when hit with light, a behavior not seen in conventional semiconductors. This effect, called photostriction, can be finely tuned depending on the light’s intensity and color. Researchers say these materials act more like adjustable systems than simple switches. The finding could lead to a new generation of light-powered sensors and devices. Read more ›

A breakthrough urine test could dramatically speed up how doctors treat urinary tract infections, identifying the right antibiotic in under six hours instead of waiting days. By testing directly from urine—skipping the usual lab culturing step—the method quickly shows which drugs stop bacterial growth and which don’t. In trials involving hundreds of patient samples, the test proved highly accurate, matching standard methods in over 96% of cases. Read more ›

Scientists at the University of Waterloo have uncovered a bold new way to explain how the universe began—one that could reshape our understanding of the Big Bang. Instead of relying on patched-together theories, their approach shows that the universe’s explosive early growth may arise naturally from a deeper framework called quantum gravity. Read more ›

Deep sleep does far more than rest the body — it activates a powerful brain-driven system that controls growth hormone, fueling muscle and bone strength, metabolism, and even mental performance. Scientists have now mapped the neural circuits behind this process, uncovering a delicate feedback loop in which sleep boosts growth hormone, and that same hormone helps regulate wakefulness.

Scientists have discovered something that seems almost impossible: under the right conditions, ordinary liquids can snap apart like solid objects. In experiments, researchers found that when certain liquids are stretched with enough force, they don’t just thin and flow—they suddenly fracture with a sharp break, much like metal under stress. This surprising behavior appears to be tied to viscosity, not elasticity, challenging long-held assumptions about how liquids behave. Read more ›

Certain smaller sauropods could stand on their hind legs with surprising ease, giving them access to higher food and a defensive edge. Computer simulations show their bones handled stress better than those of their larger relatives. However, as they grew, the sheer weight made this posture much harder to sustain. What started as a useful trick in youth became a more limited, strategic move in adulthood. Read more ›

A major analysis of nearly 10,000 patients shows that simple, non-drug treatments like knee braces, hydrotherapy, and exercise can significantly ease knee osteoarthritis symptoms. These approaches not only reduce pain and improve mobility, but also avoid the risks tied to common medications. The findings suggest that low-cost, accessible therapies could play a bigger role in how doctors treat arthritis in the future. Read more ›

Astronomers have spotted a bizarre cosmic explosion that refuses to play by the rules—and it’s leaving scientists scrambling for answers. GRB 250702B, detected by NASA’s James Webb Space Telescope and a global network of observatories, lasted an astonishing seven hours—far longer than typical gamma-ray bursts, which usually fade in under a minute.

A blazing supermassive black hole can influence far more than its own galaxy. Scientists found that quasars emit radiation strong enough to shut down star formation in nearby galaxies millions of light-years away. This could explain why some galaxies near early quasars appear faint or missing. The finding suggests galaxies grow and evolve together, not in isolation. Read more ›

A large U.S. study reveals that more than a quarter of people with hard-to-treat high blood pressure may have an overlooked hormone problem. Elevated cortisol—often linked to stress—was found in 27% of these patients, far higher than expected. This hidden condition could explain why standard medications fail. The discovery could lead to new testing and treatments that finally help bring blood pressure under control. Read more ›

A powerful cholesterol-lowering drug may be changing the rules of heart disease prevention. Researchers found that evolocumab, typically used for people who already have cardiovascular disease, can significantly cut the risk of first-time heart attacks and strokes in high-risk patients with diabetes—even before any artery-clogging plaque is detected.

Just a few minutes of getting out of breath each day could dramatically cut your risk of major diseases—including heart disease, dementia, and diabetes. A large study of nearly 100,000 people found that it’s not just how much you move, but how intensely you move that matters. Short bursts of vigorous activity—like rushing for a bus or climbing stairs quickly—were linked to striking reductions in disease risk, especially for inflammatory... Read more ›

Scientists may have been unknowingly inflating microplastics pollution estimates, and the surprising source could be their own lab gloves. A University of Michigan study found that common nitrile and latex gloves release tiny particles called stearates, which closely resemble microplastics and can contaminate samples during testing. In some cases, this led to wildly exaggerated results, forcing researchers to track down the unexpected culprit. Read more ›

Making babies in space may be more complicated than expected, as new research shows sperm struggle to navigate in microgravity. Scientists found that while sperm can still swim normally, they lose their sense of direction without gravity, making it harder to reach and fertilize an egg. In lab experiments simulating space conditions, far fewer sperm successfully made it through a maze designed to mimic the reproductive tract, and fertilization rates... Read more ›

Far beneath the ocean near Japan, scientists have discovered that the magma system linked to the most powerful eruption of the Holocene is slowly rebuilding. By using seismic imaging, researchers mapped a large magma reservoir under the Kikai caldera and confirmed it is the same system that fueled the massive eruption 7,300 years ago. However, the magma now present is newly injected, not leftover, as shown by changes in the... Read more ›

Scientists have finally found a hidden “critical point” in supercooled water that explains why it behaves so strangely. At this point, two different liquid forms of water merge, triggering powerful fluctuations that affect water even at normal temperatures. The breakthrough was made possible by ultra-fast X-ray lasers that captured water before it froze. This discovery could reshape our understanding of water’s role in nature—and possibly even life itself. Read more ›

A team of physicists set out to test some of the most exciting claims in quantum computing—and found a very different story. Instead of confirming breakthroughs, their careful replication studies revealed that signals once hailed as major advances could actually be explained in simpler ways. Despite the importance of these findings, their work initially struggled to get published, highlighting a deeper issue in science. Read more ›
