    Schneeball Erde: Wetterzyklen selbst während der schlimmsten Eiszeit der Erdgeschichte
    07/02/26 10:00:00
    Einst war die Erde komplett vereist, und das Wetter kam zum Erliegen. Doch außergewöhnliche Gesteinsschichten zeigen, dass es manchmal trotzdem Wettermuster ähnlich wie heute gab.
    Warkus’ Welt: Kann KI denken und fühlen?

    Scientists create smart synthetic skin that can hide images and change shape
    06/02/26 17:09:31
    Inspired by the shape-shifting skin of octopuses, Penn State researchers developed a smart hydrogel that can change appearance, texture, and shape on command. The material is programmed using a special printing technique that embeds digital instructions directly into the skin. Images and information can remain invisible until triggered by heat, liquids, or stretching.
    A hidden brain effect of prenatal alcohol exposure
    06/02/26 11:26:39
    New research using rhesus monkeys suggests that the brain’s relationship with alcohol may begin forming long before a person ever takes a drink. Scientists found that exposure to alcohol before birth reshaped the brain’s dopamine system, a key player in motivation and reward, and those changes were linked to faster drinking later in adulthood.
    Scientists found a sugar that could defeat deadly superbugs
    06/02/26 10:09:04
    Scientists in Australia have uncovered a clever new way to fight some of the most dangerous drug-resistant bacteria by targeting a sugar that exists only on bacterial cells. By designing antibodies that recognize this unique sugar, researchers were able to guide the immune system to attack and eliminate deadly infections that normally shrug off antibiotics.
    An invisible chemical rain is falling across the planet
    06/02/26 09:17:32
    A new study reveals that chemicals used to replace ozone-damaging CFCs are now driving a surge in a persistent “forever chemical” worldwide. The pollutant, called trifluoroacetic acid, is falling out of the atmosphere into water, land, and ice, including in remote regions like the Arctic. Even as older chemicals are phased out, their long lifetimes mean pollution is still rising.
    Why colorectal cancer breaks the immune system’s rules
    06/02/26 17:03:34
    Colorectal cancer has long baffled scientists because, unlike most tumors, patients often do better when their cancers are packed with immune-suppressing regulatory T cells. New research finally explains why. Scientists discovered that these T cells aren’t all the same: one subtype actually helps keep tumors in check, while another shields cancer from immune attack. The balance between these “good” and “bad” cells can determine whether a tumor grows or shrinks.
