    Paläontologie: Riesiges »Meerungeheuer« in Marokko enteckt
    08/03/26 14:00:00
    In Marokko befindet sich eine der wichtigsten Fossilienlagerstätten der Erde. Sie brachte nun ein weiteres Fossil eines walgroßen Mosasauriers hervor.
    Freistetters Formelwelt: Was ist das Nichts?
    08/03/26 12:00:00
    Das Nichts ist in der Mathematik genauso wichtig wie die Unendlichkeit – und oft genauso schwer zu verstehen.
    Erste globale Bestandsaufnahme: Invasive große Tiere in Seen: Jede zweite Art macht Probleme
    08/03/26 11:00:00
    Forscher zählen weltweit 93 große invasive Arten in Süßgewässern. Jede Zweite davon richtet Schäden an – oft mit Folgen für Umwelt und Menschen.
    Quantenkosmologie: Das Paradoxon fehlender Information im Universum
    08/03/26 10:18:00
    Verbindet man Quantenphysik und Kosmologie, stößt man auf ein Universum, das überraschend simpel wirkt – zu simpel. Die überraschende Rolle eines Beobachters soll das Rätsel lösen.

    Satellites are exposing weak bridges in America and around the world
    08/03/26 11:38:15
    Satellites are giving scientists a powerful new way to watch over the world’s bridges. Using radar imaging, researchers can detect millimeter-scale movements that may signal early structural problems long before inspectors notice them. The study found many bridges—especially in North America—are aging and increasingly vulnerable, but satellite monitoring could sharply reduce the number classified as high-risk. The approach could be especially valuable in regions where traditional monitoring barely exists.
    Scientists say this simple diet change could transform your gut health
    08/03/26 20:57:15
    A growing trend called “fibermaxxing” is putting dietary fiber in the spotlight—and for good reason. Fiber plays a powerful role in keeping the body healthy, from supporting digestion and feeding beneficial gut microbes to helping regulate blood sugar and cholesterol. Researchers say getting enough fiber may even lower the risk of conditions like obesity, diabetes, and certain cancers.
    Scientists stunned to find signs of ancient life in a place no one expected
    08/03/26 22:31:54
    While exploring ancient seabeds in Morocco, scientists discovered strange wrinkle-like textures in deep-water sediments that shouldn’t have been there. These structures are usually made by sunlight-loving microbial mats in shallow waters. But the rocks formed far below the reach of light, suggesting a different explanation. Evidence points to chemosynthetic microbes—organisms powered by chemical reactions—creating the mats in the dark depths of an ancient ocean.
    165,000 dementia patients reveal hidden stroke risk from common drug
    08/03/26 21:45:01
    A massive UK study of more than 165,000 dementia patients has uncovered troubling new evidence about risperidone, a commonly used drug for severe agitation. Researchers found the antipsychotic increases stroke risk in dementia patients across the board—including those with no prior heart disease or stroke—challenging the long-held belief that some patients might be safer candidates than others. Because risperidone is the only drug of its type licensed for dementia, doctors often use it as a last resort when distressing symptoms become unmanageable.
    A perfectly balanced atom just broke one of nuclear physics’ biggest rules
    08/03/26 07:01:02
    Physicists have discovered a surprising new “Island of Inversion” in a place no one expected: among nuclei where the number of protons equals the number of neutrons. For decades, these strange regions—where atomic nuclei abandon their usual orderly structure and become strongly deformed—were thought to exist only in highly neutron-rich isotopes far from stability. But experiments on molybdenum isotopes revealed that molybdenum-84 behaves dramatically differently from its close neighbor molybdenum-86, even though they differ by just two neutrons.
