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.

How the Microvasculature Drives the Human Aging Process
Recent research highlights the microvasculature as a central driver of human aging, with capillary rarefaction, endothelial dysfunction, and glycocalyx degradation limiting oxygen delivery to cells. This vascular decline triggers low‑grade hypoxia, inflammation, and mitochondrial inefficiency, linking it to age‑related diseases such as dementia, heart failure, and diabetic complications. Interventions that enhance microvascular health—exercise, shear‑stress‑induced nitric oxide, and emerging evidence for GLP‑1 and SGLT2 therapies—show promise in preserving metabolic resilience and longevity.
