A hidden “backup heater” that helps burn fat and boost metabolism18:06 Scientists have uncovered a surprising new way the body can burn energy and stay warm. Deep inside fat tissue, they found a hidden system that helps the body use up calories, even without exercise. By studying mice, researchers discovered that brown fat — the type that keeps us warm — has a backup “heater” that kicks in when needed. Tiny asteroid flew right over Antarctica, and no one saw it coming18:06 Asteroid 2025 TF zipped past Earth above Antarctica, coming within 428 km of the surface. Roughly the size of a small car, it was detected hours after the flyby and posed no danger. ESA astronomers later confirmed its trajectory with extraordinary accuracy. JWST spots a hidden red supergiant just before it exploded18:06 The James Webb Space Telescope has uncovered a massive red supergiant star just before it exploded, finally solving a cosmic mystery. Hidden beneath layers of dust, the doomed star revealed itself through Webb’s infrared eyes. The finding shows that many massive stars do explode but are obscured from view — until now. Scientists stunned by wild Martian dust devils racing at hurricane speeds18:06 Mars may look calm, but new research reveals it’s a world of fierce winds and swirling dust devils racing at hurricane-like speeds. Using deep learning on thousands of satellite images from European orbiters, scientists have discovered that Martian winds can reach up to 160 km/h — much stronger than previously thought. These powerful gusts play a key role in shaping the planet’s weather and clima… Common medications may secretly rewire your gut for years18:06 Drugs taken years—even decades—ago can leave lasting imprints on the gut microbiome, reshaping the community of microbes long after treatment stops. Scientists analyzing over 2,500 Estonian Biobank samples discovered that antibiotics aren’t the only culprits—antidepressants, beta-blockers, and anxiety medications also disrupt gut ecosystems. Some drugs from the same class even have different micr… Glowing shark and hidden crab found deep off Australia18:06 In a stunning glimpse into the mysteries of the deep, scientists have uncovered two new marine species off Western Australia—a glowing lanternshark and a tiny porcelain crab. The discoveries, made from specimens collected during a 2022 CSIRO research voyage, highlight both the dazzling adaptations of life in the deep sea and the vast number of species yet to be described. Scientists shocked as birds soaked in “forever chemicals” still thrive18:06 Tree swallows in polluted U.S. regions are accumulating high levels of “forever chemicals.” These durable pollutants, used in firefighting foams and consumer products, are found everywhere from soil to human blood. Surprisingly, researchers observed no significant impact on the birds’ reproduction, suggesting possible resilience in wild populations. Scientists suggest the brain may work best with 7 senses, not just 56:20 Scientists at Skoltech developed a new mathematical model of memory that explores how information is encoded and stored. Their analysis suggests that memory works best in a seven-dimensional conceptual space — equivalent to having seven senses. The finding implies that both humans and AI might benefit from broader sensory inputs to optimize learning and recall. Scientists reveal green tea’s fat-burning secret5:48 New research shows green tea may help the body burn fat and balance blood sugar. In a study with obese mice, it improved metabolism and muscle health without harming lean animals. Scientists say its powerful plant compounds work together to regulate fat and energy use. The findings hint that green tea could be a natural support for healthy weight management. Scientists just found a molecule that could stop Parkinson’s in its tracks5:48 Researchers have designed a peptide that prevents the deadly misfolding of alpha-synuclein, the protein behind Parkinson’s and some dementias. In lab and animal tests, it stabilized the protein and improved motor function. The work demonstrates the power of rational drug design in tackling brain diseases that have long lacked effective treatments. New pill could finally control stubborn high blood pressure5:48 A new pill called baxdrostat may offer hope for people whose blood pressure stays high even after taking standard medications. In a recent study, the drug lowered blood pressure and also seemed to protect the kidneys by reducing signs of damage. Doctors say this could help millions of people with chronic kidney disease, a condition that often makes blood pressure harder to control. Scientists just proved the moai could walk, solving a 500-year mystery8.října Researchers confirmed that Rapa Nui’s moai statues could “walk” upright using a rocking motion, aided by rope and just a few people. Experiments with replicas and 3D models revealed design features like a forward lean and curved bases that made movement possible. Concave roads across the island further supported this transport method. The findings celebrate the innovation and intelligence of the … Scientists discover orchids sprouting from decaying wood8.října Kobe University researchers found that orchids rely on wood-decaying fungi to germinate, feeding on the carbon from rotting logs. Their seedlings only grow near deadwood, forming precise fungal partnerships that mirror those seen in adult orchids with coral-like roots. This discovery highlights a hidden carbon pathway in forest ecosystems and explains the evolution of fully fungus-dependent orchi… Record Amazon fires release more carbon than an entire country8.října The Amazon has suffered its most destructive fire season in more than two decades, releasing a staggering 791 million tons of carbon dioxide—on par with Germany’s annual emissions. Scientists found that for the first time, fire-driven degradation, not deforestation, was the main source of carbon emissions, signaling a dangerous shift in the rainforest’s decline. Using advanced satellite systems a… Scientists unlock the quantum magic hidden in diamonds8.října Researchers have found a way to extract almost every photon from diamond color centers, a key obstacle in quantum technology. Using hybrid nanoantennas, they precisely guided light from nanodiamonds into a single direction, achieving 80% efficiency at room temperature. The innovation could make practical quantum sensors and secure communication devices much closer to reality. |
