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.

Scientists Map How the Body Traps 'Sleeping' Tuberculosis
Scientists at James Cook University used spatial transcriptomics to map where latent Mycobacterium tuberculosis resides within lymph nodes and bone marrow, revealing how the immune system contains the dormant bacteria. The study, published in Nature Communications, identified CD8⁺ T cells as pivotal players in this containment. By creating a novel extra‑pulmonary infection model, the researchers could test a new TB vaccine candidate aimed at preventing reactivation. With roughly 2 billion people harboring latent TB, the work offers a critical step toward reducing future active disease cases.
