Researchers in China developed a novel two-terminal β-Ga₂O₃ photo-synapse based on self-trapped holes engineering, achieving low weight update nonlinearity and excellent anti-interference characteristics. The device enables diversified in-sensor computing tasks from image classification to motion recognition, demonstrating great potential for neuromorphic machine vision systems in the artificial intelligence era.

A new study shows that the Pt/C catalyst state before ionomer addition governs later ink dispersion and electrochemical Pt accessibility.

Researchers at Osaka Metropolitan University have produced the first detailed map of molecular gas across Stephan’s Quintet, a nearby group of interacting galaxies where some regions form stars far less efficiently than expected. Their observations reveal that the effect of turbulence on star-forming gases may control whether stars are birthed or not.

This study analyzes 30 surface-water metagenomes from four functionally distinct waterbody types in Beijing, revealing starkly differentiated antibiotic resistance gene (ARG) landscapes. Urban rivers sustained the highest ARG burden, while relatively isolated urban lakes exhibited the lowest. Notably, receiving waters linked to the South-to-North Water Diversion Project maintained an intermediate load yet displayed the strongest coupling between ARGs and mobile genetic elements (R²=0.965), signaling elevated mobilization potential at these hydrological interfaces. The findings provide a foundational ecological framework for tracking resistance transport and informing risk-oriented management of megacity aquatic networks.
