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.

Study Reveals Lung-Brain Link Between Smoking and Neurodegeneration
A University of Chicago team published a study in Science Advances revealing a previously unknown lung‑brain axis that links nicotine exposure to neurodegeneration. The researchers showed that pulmonary neuroendocrine cells (PNECs) release exosomes rich in serotransferrin when stimulated by nicotine, which disrupt iron regulation in neurons. This iron dyshomeostasis triggers oxidative stress, mitochondrial dysfunction and protein aggregation—key features of Alzheimer’s and Parkinson’s disease. The work opens new avenues for therapeutic strategies targeting exosome signaling rather than just vascular damage.
