Hidden household toxin triples liver disease risk, study finds17:55 Scientists have uncovered a new environmental culprit behind liver disease: tetrachloroethylene (PCE), a chemical used in dry cleaning and household products. The study found that people with PCE exposure were three times more likely to develop severe liver scarring, even when traditional risk factors like alcohol or obesity were absent. The chemical is widespread in air, water, and consumer good… Scientists just found a material that beats diamond at its own game17:55 Boron arsenide has dethroned diamond as the best heat conductor, thanks to refined crystal purity and improved synthesis methods. This discovery could transform next-generation electronics by combining record-breaking thermal conductivity with strong semiconductor properties. A 540-million-year-old fossil is rewriting evolution17:55 Over 500 million years ago, the Cambrian Period sparked an explosion of skeletal creativity. Salterella, a peculiar fossil, defied conventions by combining two different mineral-building methods. After decades of confusion, scientists have linked it to the cnidarian family. The find deepens our understanding of how animals first learned to build their own skeletons. Scientists find 15 gut bacteria that may drive heart disease17:55 Scientists in Seoul have uncovered 15 gut bacterial species linked to coronary artery disease, showing that microbes can influence heart health far beyond digestion. Their findings reveal how shifts in gut microbial function — including inflammation, loss of protective species, and overactive metabolic pathways — may drive disease progression. Intriguingly, even “good” bacteria like Faecalibacter… New study finds Ozempic and Mounjaro protect the heart too17:55 New research from the Technical University of Munich and Harvard Medical School reveals that popular GLP-1-based drugs, semaglutide (Ozempic) and tirzepatide (Mounjaro), not only promote weight loss but also significantly reduce the risk of heart attacks and strokes in patients with type 2 diabetes. Using real-world insurance data, the study found up to an 18% reduction in major cardiovascular ev… NASA's Webb finds life’s building blocks frozen in a galaxy next door14:20 Astronomers using the James Webb Space Telescope have uncovered a trove of complex organic molecules frozen in ice around a young star in a neighboring galaxy — including the first-ever detection of acetic acid beyond the Milky Way. Found in the Large Magellanic Cloud, these molecules formed under harsh, metal-poor conditions similar to those in the early universe, suggesting that the chemical pr… Wegovy and Ozempic tied to dramatically lower cancer deaths14:20 GLP-1 drugs such as Ozempic and Wegovy may extend the lives of colon cancer patients, according to a major UC San Diego study. Patients on the medications had less than half the mortality rate of non-users. Researchers suspect the drugs’ anti-inflammatory and metabolic effects contribute to improved outcomes. They’re now calling for clinical trials to test whether these findings reflect a true an… Astronomers stunned by three Earth-sized planets orbiting two suns10:52 Scientists have identified three Earth-sized planets orbiting two stars in the TOI-2267 system. Remarkably, planets transit around both stars — a first in astronomy. The system’s compact, cold nature defies conventional theories of planetary formation. Future studies using JWST and other advanced telescopes could reveal what these worlds are truly made of. Earth is slowly peeling its continents from below, fueling ocean volcanoes9:12 Researchers discovered that continents don’t just split at the surface—they also peel from below, feeding volcanic activity in the oceans. Simulations reveal that slow mantle waves strip continental roots and push them deep into the oceanic mantle. Data from the Indian Ocean confirms this hidden recycling process, which can last tens of millions of years. Scientists shocked as bumblebees learn to read simple “Morse code”8:39 In a first-of-its-kind study, scientists found that bumblebees can tell the difference between short and long light flashes, much like recognizing Morse code. The insects learned which signal led to a sweet reward, demonstrating an unexpected sense of timing. This ability may stem from a fundamental neural process, suggesting that even tiny brains have complex time-tracking mechanisms relevant to… What brain scans reveal about soccer fans’ passion and rage8:39 Researchers scanning soccer fans’ brains found that wins trigger bursts of reward activity while losses dampen control signals. The results show how loyalty and rivalry can override logic, turning competition into an emotional storm. The same brain circuits that fuel sports passion may also underlie political or social fanaticism. Early experiences, the study suggests, shape whether these circuit… The rarest element on Earth could revolutionize cancer treatment8:39 Texas A&M scientists have unlocked new potential for astatine-211, a rare and short-lived element, as a highly precise cancer-fighting isotope. Its alpha emissions destroy tumor cells while sparing healthy tissue, making it ideal for targeted therapy. AI revives lost 3,000-year-old Babylonian hymn19:47 Researchers have rediscovered a long-lost Babylonian hymn from 1000 BCE, using artificial intelligence to piece together fragments scattered across the world. The hymn glorifies ancient Babylon’s beauty, prosperity, and inclusivity, even describing women’s priestly roles — a rarity in surviving texts. Once a school favorite, it now provides a rare glimpse into everyday life and beliefs of the cit… Entangled spins give diamonds a quantum advantage19:47 UC Santa Barbara physicists have engineered entangled spin systems in diamond that surpass classical sensing limits through quantum squeezing. Their breakthrough enables next-generation quantum sensors that are powerful, compact, and ready for real-world use. Tiny implant wipes out bladder cancer in 82% of patients19:47 TAR-200, a small drug-releasing implant, wiped out tumors in most patients with high-risk bladder cancer. Its slow, consistent release of chemotherapy proved far more effective than traditional short-term treatments. The therapy may replace bladder removal surgery for many and has earned FDA Priority Review due to its impressive results. |
