UK-led study reveals hidden massive star clusters deep inside nearby galaxies
Astronomers using the VLA and ALMA uncovered previously unseen giant star clusters, described as "ring factories," embedded within nearby galaxies. A complementary analysis of roughly 18,000 star‑forming regions showed that the energetic activity of young stars plays a decisive role in shaping galaxy evolution.

Entanglement’s Dynamic Response Reveals Connections Between Complex States of Matter
Researchers demonstrated that two entanglement measures respond predictably to modular flow, a real‑time evolution driven by the entanglement Hamiltonian. They unified these responses in a single generating function that generalises the Rényi commutator and directly encodes chiral topological invariants such as the chiral central charge and Hall conductance. The analytical framework was validated on free‑fermion models and through effective field theory regularised by chiral conformal field theory. This establishes entanglement dynamics as a precise diagnostic for topological order in quantum materials.
