Astronomers have taken a fresh look at the famous “Hand of God” pulsar, combining X-ray data from NASA’s Chandra Observatory with new radio observations from the Australia Telescope Compact Array. At the center is pulsar B1509-58, a rapidly spinning neutron star only about 12 miles wide that powers a nebula stretching 150 light-years across. The strange hand-shaped structure continues to surprise…

A breakthrough pill, baxdrostat, has shown remarkable success in lowering dangerously high blood pressure in patients resistant to standard treatments. In a large international trial, it cut systolic pressure by nearly 10 mmHg, enough to significantly reduce risks of heart attack, stroke, and kidney disease. The drug works by blocking excess aldosterone, a hormone that drives uncontrolled hyperte…

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.

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…

Stanford researchers reveal meandering rivers existed long before plants, overturning textbook geology. Their findings suggest carbon-rich floodplains shaped climate for billions of years.

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…

New research suggests that exercise may not just make us feel younger—it could actually slow or even reverse the body’s 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…

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 oxide—a molecule vital for vascular health.

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 B…

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 fingerp…

Mars isn’t the neatly layered world we once imagined — its mantle is filled with ancient, jagged fragments left over from colossal impacts billions of years ago. Seismic data from NASA’s InSight mission revealed that these buried shards, some up to 4 km wide, are still preserved beneath the planet’s stagnant crust, acting as a geological time capsule.

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. So…

Researchers at the University of Colorado Boulder have unveiled an AI-powered system designed to expose predatory scientific journals—those 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.

Spicomellus afer, a newly analyzed Jurassic ankylosaur from Morocco, is overturning scientists’ 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 fo…

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.
