Beta blockers, used for decades after heart attacks, provide no benefit for patients with preserved heart function, according to the REBOOT trial. The massive study also found women faced higher risks when taking the drug. Experts say the results will change heart treatment guidelines worldwide. Read more âș

As the Great Salt Lake shrinks, scientists are uncovering mysterious groundwater-fed oases hidden beneath its drying lakebed. Reed-covered mounds and strange surface disturbances hint at a vast underground plumbing system that pushes fresh water up under pressure. Using advanced tools like airborne electromagnetic surveys and piezometers, researchers are mapping the hidden freshwater reserves and testing whether they could help restore fragile lakebed crusts, reduce dust pollution, and reveal long-buried se Read more âș

New research suggests that exercise may not just make us feel youngerâit could actually slow or even reverse the bodyâs molecular clock. By looking at DNA markers of aging, scientists found that structured exercise like aerobic and strength training has stronger anti-aging effects than casual activity. Evidence from both mice and humans shows measurable reductions in biological age, with benefits reaching beyond muscles to the heart, liver, fat tissue, and... Read more âș

Drinking nitrate-rich beetroot juice lowered blood pressure in older adults by reshaping their oral microbiome, according to researchers at the University of Exeter. The study found that beneficial bacteria increased while harmful ones decreased, leading to better conversion of dietary nitrates into nitric oxideâa molecule vital for vascular health. Read more âș

A massive global study uncovered a striking paradox: even as total burned land has dropped by more than a quarter since 2002, human exposure to wildfires has skyrocketed. Africa accounts for a staggering 85% of these exposures, while California stands out as an extreme hotspot despite its relatively small share of burned land. Climate change is fueling more intense fire weather, population growth is pushing communities into fire-prone landscapes, and... Read more âș

Astronomers at the University of Missouri, using the James Webb Space Telescope, have uncovered 300 unusually bright cosmic objects that may be some of the earliest galaxies ever formed. By applying techniques like infrared imaging, dropout analysis, and spectral energy distribution fitting, the team has identified candidates that could force scientists to rethink how galaxies emerged after the Big Bang.

Astronomers using the James Webb Space Telescope have uncovered a planet-forming disk shockingly rich in carbon dioxide but nearly devoid of water, upending traditional theories of planetary chemistry. Found in a harsh star-forming region flooded with radiation, the discovery hints that cosmic environments may drastically reshape the ingredients that shape planets. The unexpected isotopic fingerprints of CO2 could even help solve mysteries about the origins of meteorites and comets in... Read more âș

Mars isnât the neatly layered world we once imagined â its mantle is filled with ancient, jagged fragments left over from colossal impacts billions of years ago. Seismic data from NASAâs InSight mission revealed that these buried shards, some up to 4 km wide, are still preserved beneath the planetâs stagnant crust, acting as a geological time capsule.

Spicomellus afer, a newly analyzed Jurassic ankylosaur from Morocco, is overturning scientistsâ understanding of dinosaur evolution. Unlike any other known creature, it carried a collar of meter-long spikes fused directly to its ribs, along with an early form of tail weaponry that predates similar adaptations by over 30 million years. These bizarre features suggest its armor may have been used for show as well as protection, before shifting toward defense... Read more âș

Researchers at the University of Colorado Boulder have unveiled an AI-powered system designed to expose predatory scientific journalsâthose that trick scientists into paying for publication without proper peer review. By analyzing journal websites for red flags like fake editorial boards, excessive self-citation, and sloppy errors, the AI flagged over 1,400 suspicious titles out of 15,200. Read more âș

Scientists at Mount Sinai have created an artificial intelligence system that can predict how likely rare genetic mutations are to actually cause disease. By combining machine learning with millions of electronic health records and routine lab tests like cholesterol or kidney function, the system produces "ML penetrance" scores that place genetic risk on a spectrum rather than a simple yes/no. Some variants once thought dangerous showed little real-world impact, while... Read more âș

Scientists have uncovered a surprising new healing mechanism in injured cells called cathartocytosis, in which cells "vomit" out their internal machinery to revert more quickly to a stem cell-like state. While this messy shortcut helps tissues regenerate faster, it also leaves behind debris that can fuel inflammation and even cancer. Read more âș

Men eating ultra-processed foods gained more fat than those eating unprocessed meals, even with equal calories. Their hormone levels shifted in worrying ways, with testosterone falling and pollutants rising. Researchers say the processing itself, not overeating, is to blame. Read more âș

Scientists have finally uncovered direct genetic evidence of Yersinia pestis â the bacterium behind the Plague of Justinian â in a mass grave in Jerash, Jordan. This long-sought discovery resolves a centuries-old debate, confirming that the plague that devastated the Byzantine Empire truly was caused by the same pathogen behind later outbreaks like the Black Death.

Astronomers have spotted 3I/ATLAS, just the third interstellar object ever seen in our solar system. Bigger, faster, and possibly far older than âOumuamua or Borisov, this icy traveler could help unlock clues about how other star systems formed billions of years ago. Read more âș

Yale scientists discovered that cavefish species independently evolved blindness and depigmentation as they adapted to dark cave environments, with some lineages dating back over 11 million years. This new genetic method not only reveals ancient cave ages but may also shed light on human eye diseases. Read more âș

Scientists have identified a new giant lizard, Bolg amondol, from Utahâs Kaiparowits Formation, named after Tolkienâs goblin prince. Part of the monstersaur lineage, Bolg reveals that multiple large lizards coexisted with dinosaurs, suggesting a thriving ecosystem. Its discovery in long-stored fossils underscores how museums hold hidden scientific gems. Read more âș

Seventy million years ago, southern Patagonia was home to dinosaurs, turtles, and mammalsâbut also to a fierce crocodile-like predator. A newly discovered fossil, astonishingly well-preserved, reveals Kostensuchus atrox, a powerful 3.5-meter-long apex predator with crushing jaws and sharp teeth capable of devouring medium-sized dinosaurs. As one of the largest hunters of its time and the first of its kind found in the Chorrillo Formation, this find offers rare insight into... Read more âș

Quantum scientists in Innsbruck have taken a major leap toward building the internet of the future. Using a string of calcium ions and finely tuned lasers, they created quantum nodes capable of generating streams of entangled photons with 92% fidelity. This scalable setup could one day link quantum computers across continents, enable unbreakable communication, and even transform timekeeping by powering a global network of optical atomic clocks that are so...
