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.

Re: RSV Vaccination Programme Expanded to 3 Million More Older People
The UK health authorities have announced an expansion of the RSVpreF (Abrysvo) vaccination programme to include an additional three million adults aged 60 and older. Clinical trial data published in the New England Journal of Medicine confirm the vaccine’s ability to cut hospital admissions for RSV‑related respiratory disease. However, the same trial reported a modest excess in all‑cause mortality among vaccinated participants—152 deaths out of 65,648 (0.23%) versus 129 deaths out of 65,644 (0.20%) in the control group. The findings have sparked debate over the vaccine’s overall safety profile as the rollout proceeds.
