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.

Active Matter that Can Crawl, Walk and Dig Challenges Classical Engineering Principles
Researchers from Amsterdam, Cambridge and the University of New South Wales have created active materials by linking rods with tiny motors, producing non‑reciprocal interactions that turn ordinary buckling into a repeatable, oscillating process. The resulting filaments can crawl, walk and even dig, a behavior highlighted on the cover of PNAS. In a separate study, the same team showed that in two‑dimensional lattices, adding more active components can paradoxically make the bulk material less responsive, defying Le Chatelier’s principle. These findings open new routes for autonomous, soft robotic structures.
