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.

Alpheus Medical Advances to Phase 2b Testing of Experimental Brain Cancer Therapy
Alpheus Medical has enrolled 10 patients in a Phase 2b randomized trial of its Porphyrin Metabolite Activation (PoMA) therapy for newly diagnosed glioblastoma. PoMA uses a tumor‑selective drug activated by low‑intensity diffuse ultrasound to treat the entire affected brain hemisphere, aiming to overcome the disease’s infiltrative nature. The study will eventually enroll more than 100 patients across up to 15 U.S. and European sites, with progression‑free survival as the primary endpoint. Early enrollment signals strong interest and could reshape glioblastoma treatment if efficacy is demonstrated.
