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.

Asteroids with tiny moons may be quietly trading material across space. Images from NASA’s DART mission revealed faint streaks on the moon Dimorphos—evidence of slow “cosmic snowballs” drifting from its parent asteroid, Didymos. The discovery provides the first direct visual proof that sunlight can spin asteroids fast enough to shed debris that lands on nearby companions. It also shows that near-Earth asteroids are much more active and constantly reshaped than scientists once believed.

Researchers have uncovered a surprising molecular chain reaction in the brain that may play a role in some forms of autism. The study suggests that nitric oxide, a tiny signaling molecule normally involved in fine-tuning communication between brain cells, can sometimes trigger a cascade of changes inside neurons. When nitric oxide activity rises, it can alter a protective protein called TSC2, weakening an important cellular brake and allowing the mTOR pathway, which controls growth and protein production, to become overactive.

Solid-state batteries could be safer and more energy-dense than today’s lithium-ion technology, but finding materials that allow ions to move quickly through solid electrolytes has been difficult. Researchers developed a machine learning pipeline that predicts Raman spectra and identifies a distinctive low-frequency signal linked to liquid-like ion motion inside crystals. This signal appears when rapid ion movement temporarily disrupts a crystal’s symmetry. The approach could dramatically speed up the discovery of superionic materials for advanced batteries.

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.
