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.

Maternal Exposure to Short-Chain PFAS Causes Persistent Memory Problems in Adult Rats
Researchers at the University of Bologna found that prenatal and lactational exposure to short‑chain PFAS chemicals—specifically GenX and PFBA—produces lasting memory and learning deficits in adult rats. The study administered low‑dose contaminated diets to pregnant females, then evaluated offspring behavior, hippocampal structure, and molecular markers after the chemicals had cleared from the brain. Exposed rats showed slower spatial learning, reduced synaptic formation, heightened brain inflammation, and altered sex hormone levels. These findings suggest that even non‑acutely toxic PFAS can disrupt neurodevelopmental processes.
