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.

AI in Science
The paper by Agrawal, McHale and Oettl frames artificial intelligence as an augmentation tool that expands scientists' ability to search combinatorial spaces, rather than fully automating research. By dissecting the knowledge‑production process into stages, the authors reveal a “jagged frontier” where AI delivers uneven returns across fields—data‑rich biology sees larger gains than anomaly‑sparse physics. Tools such as AlphaFold provide strong design assistance, while subtler question‑generation systems support ideation. Human judgment remains indispensable for abductive inference and nuanced trade‑offs, especially in data‑sparse environments, highlighting the need for AI‑expert training and organizational redesign.
This Overlooked Organ May Be More Vital for Longevity than Scientists Realized
