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.

Monash University Research Highlights Safer, Smarter Human-Robot Teamwork in Manufacturing
Monash University researchers published a review in the International Journal of Production Research showing that better prediction of human behaviour by robots can make manufacturing safer, more adaptive and efficient as Industry 5.0 evolves. The study compares mechanism‑based, data‑driven and hybrid prediction models, concluding that integrated approaches deliver the strongest performance. It highlights challenges such as human variability, scarce multimodal datasets, and the need to account for trust and cognitive load. The authors propose a unified framework that combines multimodal data, physical modelling and adaptive control to improve human‑robot teamwork.

Paradoxical Role of the Mesocorticolimbic Netrin1-DCC Pathway in Social Competition and Vulnerability to Methamphetamine Abuse During Adolescence
Researchers discovered that adolescent social competition up‑regulates the mesocorticolimbic Netrin‑1/DCC pathway, reshaping dopamine projections in the prefrontal cortex and heightening methamphetamine self‑administration in mice. Elevated DCC expression conferred social dominance but simultaneously increased drug‑seeking behavior. Pharmacological blockade of DCC reduced...

BDNF Restores Impaired Long-Term Potentiation of GABAergic Synapses Induced by Chronic Ethanol Exposure in the VTA and Attenuates Reward-Seeking Behavior
Chronic intermittent ethanol exposure in mice reduces brain‑derived neurotrophic factor (BDNF) levels in the ventral tegmental area (VTA) and abolishes long‑term potentiation of GABAergic synapses (LTP GABA) onto dopamine neurons. This impairment is presynaptic, leading to heightened dopamine neuron activity during...
