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.

Burden of Colon and Rectum Cancer Attributable to a Diet High in Red Meat in the United States, 1990–2021
A new analysis of Global Burden of Disease 2021 data estimates that 12,053 colorectal cancer deaths in the United States in 2021 were attributable to a diet high in red meat. Age‑standardized mortality and DALY rates have declined modestly since 1990 (EAPC −1.69% and −1.38% respectively), yet deaths among adults aged 25‑49 are rising. The burden varies sharply by state, with Mississippi, Louisiana and West Virginia showing the highest age‑standardized rates. Decomposition shows population growth, not worsening risk, as the primary driver of the rising absolute death count.
