    Ahnungslosigkeit als Schritt zu echter Erkenntnis? So will es die sokratische Methode. Bis heute fördert sie das Lernen in Schulen und Hochschulen, wie unser Kolumnist weiß.
    Unwahrscheinlich tödlich: Tod durch Lachen
    07/03/26 09:53:00
    Ein Lachkrampf ist zwar in der Regel komplett harmlos – doch in seltenen Fällen besteht eine gewisse Gefahr, sich dabei zu verletzen oder sogar einen Herzinfarkt zu erleiden.
    Historische Duftforschung: Forscher machen historische Gerüche wieder erlebbar

    Auch Gerüche müssen vor dem Verschwinden gerettet werden, sagen Dufthistoriker – zumal der Duft uns wie kein anderer Sinn in die Vergangenheit katapultieren kann.

    Mayo Clinic discovers rare gene mutation that causes fatty liver disease
    07/03/26 12:04:29
    Mayo Clinic researchers have identified a rare mutation in the MET gene that can directly cause metabolic dysfunction-associated steatotic liver disease. The mutation disrupts the liver’s ability to process fat, leading to inflammation, scarring, and potentially cirrhosis. The discovery began with a father and daughter who had the disease without typical risk factors. Large-scale genomic data suggests similar rare variants may quietly contribute to the disease in many more people.
    A 4,000-year-old sheep reveals the secret of an ancient plague
    07/03/26 09:41:28
    A mysterious form of plague that spread across Eurasia thousands of years before the Black Death has finally revealed a crucial clue. Scientists analyzing ancient DNA discovered the bacterium Yersinia pestis in a 4,000-year-old domesticated sheep from a Bronze Age settlement in the Ural Mountains—the first time the pathogen has ever been found in a non-human host from that era. Because this early strain couldn’t spread through fleas like the medieval plague, researchers have long puzzled over how it traveled so widely.
    Scientists discover protein that triggers diabetic blindness
    07/03/26 10:48:42
    A newly identified protein may hold the key to preventing diabetic blindness. Researchers discovered that LRG1 triggers the earliest damage in diabetic retinopathy by constricting tiny retinal blood vessels and reducing oxygen supply. In mice, shutting down this protein stopped the damage before it could take hold. The finding could pave the way for treatments that protect vision before symptoms ever begin.
    Physicists finally see strange magnetic vortices predicted 50 years ago
    07/03/26 06:36:21
    A team of physicists has experimentally confirmed a long-predicted sequence of exotic magnetic phases in an atomically thin material. When cooled, the material forms tiny magnetic vortices before transitioning into a second ordered magnetic state—exactly as predicted by a famous theoretical model from the 1970s. Observing both phases together for the first time validates key ideas about how magnetism behaves in two dimensions. The findings could help inspire ultracompact technologies built on nanoscale magnetic control.
    Antarctica has a strange gravity hole and scientists finally know why
    07/03/26 06:45:53
    Gravity may seem constant, but it actually varies across the planet—and one of the strangest places is Antarctica, where gravity is slightly weaker than expected. Scientists have traced this “gravity hole” to slow, deep movements of rock inside Earth that unfolded over tens of millions of years. Using earthquake data to essentially create a CT scan of the planet’s interior, researchers reconstructed how the anomaly evolved and discovered that it strengthened between about 50 and 30 million years ago.
