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.

Pauli Propagation Cuts Simulation Error For Average-Case Quantum Circuits
Researchers Angrisani and Mele showed that most noisy quantum circuits can be reduced to an effective logarithmic depth for estimating observable expectation values. By applying Pauli‑propagation algorithms with a carefully designed truncation, the simulation error drops inversely polynomially as circuit size grows. The method works for arbitrary local noise, including amplitude damping and dephasing, and was validated on 6×6 and 11×11 qubit lattices. These results broaden the class of quantum systems that can be efficiently simulated on classical hardware.
