UK-led study reveals hidden massive star clusters deep inside nearby galaxies
Astronomers using the VLA and ALMA uncovered previously unseen giant star clusters, described as "ring factories," embedded within nearby galaxies. A complementary analysis of roughly 18,000 star‑forming regions showed that the energetic activity of young stars plays a decisive role in shaping galaxy evolution.

High‑fat Diets Linked to Rapid Decline in Protective Gut Immune Cells
A preclinical study from Mass General Brigham shows that short‑term consumption of a high‑fat diet rapidly depletes intestinal group 3 innate lymphoid cells (ILC3s). The loss, driven by microbiota‑induced inflammation and mitochondrial stress, reduces IL‑22 production, increases gut permeability, and sparks inflammation. Th17 cells remain largely unaffected, highlighting a selective vulnerability. The researchers found that switching to a lower‑fat diet can restore ILC3 levels, suggesting early dietary intervention could mitigate barrier dysfunction and related chronic diseases.
