1. Inside the mysterious collapse of dark matter halos

   Physicists have unveiled a new way to simulate a mysterious form of dark matter that can collide with itself but not with normal matter. This self-interacting dark matter may trigger a dramatic collapse inside dark matter halos, heating and densifying their cores in surprising ways. Until now, this crucial middle ground of behavior was nearly impossible to model accurately. The new code makes these simulations faster, more precise, and accessible enough to run on a laptop.

2. A “dormant” brain protein turns out to be a powerful switch

   Scientists at Johns Hopkins have uncovered a surprising new way to influence brain activity by targeting a long-mysterious class of proteins linked to anxiety, schizophrenia, and movement disorders. Once thought to be mostly inactive, these proteins—called GluDs—turn out to play an active role in how brain cells communicate and form connections.

3. This tiny power module could change how the world uses energy

   As global energy demand surges—driven by AI-hungry data centers, advanced manufacturing, and electrified transportation—researchers at the National Renewable Energy Laboratory have unveiled a breakthrough that could help squeeze far more power from existing electricity supplies. Their new silicon-carbide-based power module, called ULIS, packs dramatically more power into a smaller, lighter, and cheaper design while wasting far less energy in the process.

4. How the frog meat trade helped spread a deadly fungus worldwide

   A deadly fungus that has wiped out hundreds of amphibian species worldwide may have started its global journey in Brazil. Genetic evidence and trade data suggest the fungus hitchhiked across the world via international frog meat markets. The findings raise urgent concerns about how wildlife trade can spread hidden biological threats.

5. Major review finds no autism or ADHD risk from pregnancy Tylenol

   A major new scientific review brings reassuring news for expectant parents: using acetaminophen, commonly known as Tylenol, during pregnancy does not increase a child’s risk of autism, ADHD, or intellectual disability. Researchers analyzed 43 high-quality studies, including powerful sibling comparisons that help separate medication effects from genetics and family environment. Earlier warnings appear to have been driven by underlying maternal health factors such as fever or pain rather than the medication itself.
