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.

Author Correction: A PP1–PP2A Phosphatase Relay Controls Mitotic Progression
The authors of the Nature paper on the PP1‑PP2A phosphatase relay have issued a correction after a reader spotted a duplicated anti‑HA blot in Extended Data Fig. 7c. The duplicated image, originally a copy of panel e, has been replaced with the correct blot from a separate experiment, and the revised panels are now provided as supplementary material. The amendment does not alter the study’s core conclusions about mitotic progression. The correction underscores the authors’ commitment to data integrity and transparency.
