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.

HIV Remains Suppressed in Some Patients After Treatment Withdrawal
Scientists at Gladstone Institutes identified two host genes, DDIT4 and ZNF254, that act as molecular locks keeping HIV dormant after antiretroviral therapy (ART) cessation. Multi‑omic analysis of 75 participants from analytical treatment interruption trials linked higher expression of these genes, as well as stem‑cell memory CD8+ T cells and atypical NK cells, to delayed viral rebound. The common diabetes drug metformin was shown to induce DDIT4, blocking HIV reactivation in vitro, suggesting a low‑cost, repurposable pathway toward ART‑free remission. The team plans preclinical and clinical studies to test metformin’s therapeutic potential.
Occasional Use of Classic Psychedelics Linked to Enhanced Cognitive Flexibility in Young Adults
A cross‑sectional study of 136 young adults found that occasional use of classic psychedelics such as LSD and psilocybin does not impair overall cognition and may enhance mental adaptability. While test scores for memory, attention and processing speed were comparable...
