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.

SARS-CoV-2 Delta and Omicron BA.2 Show Clustered Spike D614 Reversions. What It Could Mean for Surveillance
Researchers from the University of Tsukuba and the Institute of Science Tokyo have uncovered nonrandom spike D614 reversion events in SARS‑CoV‑2, where the previously dominant G614 mutation reverted to the ancestral D614 residue. The reversions are concentrated in delta and omicron BA.2 lineages and display distinct temporal spikes and geographic clustering. Analysis of global genomic databases revealed dozens of such events, suggesting they are not random sequencing artifacts. The study highlights a previously underappreciated layer of viral plasticity.
