    Autismus bei Mädchen: Durchs Raster gefallen
    24/01/26 09:06:00
    Die bisherige Autismusforschung war zu sehr auf Männer fixiert. Betroffene Mädchen und Frauen erhalten oft keine Diagnose, weil sie ihre Symptome geschickt tarnen.

    Astronomers just revealed a stunning new view of the Milky Way in radio colors
    24/01/26 09:56:41
    A groundbreaking new radio image reveals the Milky Way in more detail than ever before, using low-frequency radio “colors” to map the galaxy’s hidden structures. The image is sharper, deeper, and wider than anything previously released, uncovering both star-forming regions and the remains of ancient stellar explosions. Scientists can now better distinguish where stars are being born versus where they’ve met dramatic ends. The discovery opens powerful new ways to study the life cycle of stars and the shape of our galaxy.
    Astronomers found a black hole growing way too fast
    24/01/26 09:27:23
    Astronomers have spotted a rare, rule-breaking quasar in the early Universe that appears to be growing its central black hole at an astonishing pace. Observations show the black hole is devouring matter far faster than theory says it should—about 13 times the usual “speed limit”—while simultaneously blasting out bright X-rays and launching a powerful radio jet. This surprising combination wasn’t supposed to happen, according to many models, and suggests scientists may be catching the black hole during a brief, unstable growth spurt.
    New catalyst makes plastic upcycling 10x more efficient than platinum
    24/01/26 10:15:29
    Scientists are finding new ways to replace expensive, scarce platinum catalysts with something far more abundant: tungsten carbide. By carefully controlling how tungsten carbide’s atoms are arranged at extremely high temperatures, researchers discovered a specific form that can rival platinum in key chemical reactions, including turning carbon dioxide into useful fuels and chemicals. Even more promising, the same material proved dramatically better at breaking down plastic waste, outperforming platinum by more than tenfold.
    Ancient giant kangaroos could hop after all
    24/01/26 05:21:29
    Giant kangaroos that lived during the Ice Age may not have been as slow and grounded as once believed. A new study finds their leg bones and tendons were likely strong enough to support hopping, despite their massive size. Rather than traveling this way all the time, these animals may have relied on short bursts of hopping. This ability could have played a key role in escaping predators.
    Chemotherapy rewires gut bacteria to block metastasis
    24/01/26 05:12:49
    Chemotherapy’s gut damage turns out to have a surprising upside. By changing nutrient availability in the intestine, it alters gut bacteria and increases levels of a microbial molecule that travels to the bone marrow. This signal reshapes immune cell production, strengthening anti-cancer defenses and making metastatic sites harder for tumors to colonize. Patient data suggest this immune rewiring is linked to better survival.
