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.

Natural Compound Obakulactone Shows Therapeutic Potential for Rheumatoid Arthritis
Researchers have identified obakulactone, a natural tetracyclic triterpenoid from Phellodendri cortex, as a promising therapeutic for rheumatoid arthritis (RA). In a CFA‑induced rat model, oral dosing (50‑200 mg·kg⁻¹·d⁻¹) over 21 days markedly reduced joint swelling, restored cartilage integrity, and modulated immune cell infiltration. Multi‑omics analyses revealed that obakulactone promotes ubiquitin‑proteasome degradation of ACOT1, normalizing unsaturated fatty‑acid metabolism and dampening JAK‑STAT/PI3K‑AKT signaling. The findings position ACOT1 inhibition and fatty‑acid reprogramming as novel anti‑RA strategies.
Nanophotonic Chips Finally Make the Proteome Visible
