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.

Folate Deficiency Correlates with Severity of Primary Biliary Cholangitis via Modulating Key Regulatory Genes
A new study of 90 primary biliary cholangitis (PBC) patients found serum folate levels significantly lower than in healthy controls and progressively reduced in late‑stage disease. Folate concentrations correlated inversely with liver enzymes, immunoglobulin G and liver stiffness measurements, and a combined panel of folate, direct bilirubin and elastography achieved an AUC of 0.974 for detecting advanced PBC. RNA‑sequencing revealed thousands of differentially expressed genes linked to metabolism and immunity, with six candidate proteins—including ARID3B, MXD1 and AHRR—validated by ELISA as folate‑responsive. The authors propose folate deficiency as both a biomarker and a potential driver of PBC progression.
