UK-led study reveals hidden massive star clusters deep within nearby galaxies
Astronomers using the VLA and ALMA uncovered previously unseen giant star clusters embedded deep inside nearby galaxies. The findings show that young stellar activity drives the evolution of these galaxies, reshaping their interstellar environments. Multiple observations confirm the clusters act as hidden “ring factories” of star formation.

Hidden Brain Switch Helps You Learn From Mistakes
Scientists at Duke and Harvard identified a hidden cerebellar circuit that resolves a long‑standing paradox: climbing fibers both trigger learning and suppress it. The circuit uses ML12 interneurons to silence ML11 inhibitory cells, briefly releasing the brain's internal brakes and allowing Purkinje cells to generate strong calcium bursts that drive plasticity. This disinhibitory mechanism is strongest when multiple climbing fibers fire together, linking sudden sensory errors to rapid motor learning. The finding opens new avenues for understanding cerebellar disorders such as ataxia and autism spectrum conditions.
