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.

Tobacco Plant Altered to Produce Five Psychedelic Drugs
Scientists at Israel's Weizmann Institute have engineered tobacco (Nicotiana benthamiana) to produce five psychedelic compounds—including psilocin, psilocybin, DMT, bufotenin and 5‑methoxy‑DMT—using agroinfiltration, a transient gene‑delivery method that does not integrate DNA into the plant genome. The approach leverages nine introduced genes to recreate the full biosynthetic pathways, offering a potentially simpler, greener alternative to chemical synthesis or wild harvesting. Researchers argue that greenhouse‑grown tobacco could serve as a scalable "green factory" for research‑grade psychedelics. They caution that permanent inheritance of these pathways would raise security and regulatory concerns.
