MIT quantum breakthrough edges toward room-temp superconductors10:22 MIT scientists uncovered direct evidence of unconventional superconductivity in magic-angle graphene by observing a distinctive V-shaped energy gap. The discovery hints that electron pairing in this material may arise from strong electronic interactions instead of lattice vibrations. Einstein might have been wrong about black holes9:19 Researchers are using black hole shadows to challenge Einstein’s theory of relativity. With new simulations and future ultra-sharp telescope images, they may uncover signs that his famous equations don’t tell the whole story. Deep-sea mining starves life in the ocean’s twilight zone9:19 Scientists have discovered that deep-sea mining plumes can strip vital nutrition from the ocean’s twilight zone, replacing natural food with nutrient-poor sediment. The resulting “junk food” effect could starve life across entire marine ecosystems. Laser satellites expose a secret Antarctic carbon burst8:15 A new study shows that the Southern Ocean releases far more carbon dioxide in winter than once thought. By combining laser satellite data with AI analysis, scientists managed to “see” through the polar darkness for the first time. The results reveal a 40% undercount in winter emissions, changing how researchers view the ocean’s carbon balance and its impact on climate models. A hidden cellular cleanup trick could reverse aging4:58 Researchers found that the body’s natural recycling system, the lysosome, plays a vital role in removing the protein that drives premature aging. When this system breaks down, aging speeds up. By reactivating it, scientists were able to help cells recover their youthful behavior. The discovery opens exciting possibilities for anti-aging treatments. Stanford makes stem cell transplants safer without chemo4:58 A Stanford-led team has replaced toxic pre-transplant chemotherapy with a targeted antibody, allowing children with Fanconi anemia to receive stem cell transplants safely. The antibody, briquilimab, removes diseased stem cells without radiation, enabling nearly complete donor cell replacement. The approach also widens donor eligibility and could soon be applied to other bone marrow failure diseas… Scientists find hidden brain damage from a common pesticide17:11 Prenatal exposure to the insecticide chlorpyrifos causes widespread brain abnormalities and poorer motor skills in children. Even after a residential ban, ongoing agricultural use continues to endanger developing brains. After 250 years, an 18th-century mechanical volcano erupts to life17:11 An 18th-century mechanical artwork depicting Mount Vesuvius’ eruption has finally erupted — 250 years later. University of Melbourne students reconstructed Sir William Hamilton’s imaginative fusion of art and engineering using modern technology. Their re-creation glows with programmable lights and movement, reanimating history’s forgotten passion for science and spectacle. Black hole blast outshines 10 trillion Suns17:11 A colossal black hole 10 billion light-years away has been caught devouring one of the universe’s biggest stars, unleashing a flare 30 times brighter than any seen before. The flare, detected by Caltech’s ZTF, likely marks a tidal disruption event — when a star is shredded by a black hole’s gravity. CERN creates cosmic “fireballs” that could reveal the Universe’s hidden magnetism17:11 Using CERN’s Super Proton Synchrotron, researchers generated plasma fireballs to simulate blazar jets. The beams stayed stable, suggesting plasma instabilities aren’t responsible for missing gamma rays. Instead, the data strengthens the idea of ancient intergalactic magnetic fields, possibly from the Universe’s earliest moments. Rare desert berry could transform diabetes treatment11:50 An extract from a desert berry used in traditional Chinese medicine restored insulin function and stabilized metabolism in diabetic mice. The findings hint at a powerful natural alternative for holistic diabetes treatment. The hidden “Big Bang” that decides how bowel cancer grows11:50 Scientists have pinpointed a “Big Bang” moment in bowel cancer—when cells first evade the immune system. This early immune escape locks in how the cancer will behave as it grows. The discovery could help predict which patients respond to immunotherapy and lead to new vaccine strategies Scientists discover how hair cells can help heal skin faster11:50 Rockefeller scientists uncovered how hair follicle stem cells can switch from growing hair to repairing skin when nutrients run low. The key lies in serine, an amino acid that activates a stress signal telling cells to conserve energy. When both injury and low serine occur, stem cells fully pivot to skin repair. The discovery could lead to dietary or medical ways to boost healing. The bright colors in your food may be harming your kids11:50 Almost 20% of packaged foods and beverages in the US contain synthetic dyes, often paired with excessive sugar to attract children. These additives have been linked to behavioral issues, yet remain widespread among major brands like Mars and PepsiCo. Experts criticize the FDA for relying on voluntary reform, contrasting it with Europe’s stricter labeling laws. Growing state-level action offers ho… Mini llama proteins show promise for Alzheimer’s treatment7.listopadu Miniature antibodies from camels and llamas can slip into the brain more easily than conventional drugs, offering a new way to treat disorders like Alzheimer’s and schizophrenia. Researchers say these “nanobodies” could reshape the future of brain medicine. |
