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.

Researchers at Beijing Institute of Technology developed a spatially shaped femtosecond-laser method for patterning quantum-dot colour-conversion pixels. The approach creates microholes down to 100 nm and produces red and green CdSe quantum-dot pixels as small as approximately 700 nm, yielding monochromatic and dual-colour arrays with high uniformity. This mask-free strategy offers a promising route toward high-resolution full-colour micro-LED displays for AR/VR and other advanced applications.

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

A new review in Medicine Plus traces a century of deep brain stimulation (DBS), explaining how the therapy alters pathological activity from local circuits to whole-brain networks, and mapping targets and clinical evidence across 16 neurological and psychiatric disorders. It also examines adaptive stimulation, directional leads, and biomarker-guided approaches that could make treatment more precise and personalized.

A new review in Medicine Plus outlines a transformative paradigm for luminal cancers using engineered microbe-based micro/nanorobots. Deployed via oral, suppository, or intracavitary routes, these living platforms bypass physiological barriers, colonize tumor niches, continuously synthesize therapeutics, and remodel the tumor microenvironment. Merging microbial adaptability with synthetic biology, they usher in an era of persistent, spatially controlled intervention.

A new review in Medicine Plus traces the evolution of mRNA lipid nanoparticles (mRNA-LNPs) from prophylactic vaccine vehicles to programmable therapeutic platforms. The authors detail clinical and preclinical progress across infectious disease, cancer, autoimmunity, rare genetic disease and tissue repair, while identifying key translational hurdles including extrahepatic targeting, repeat-dose immunogenicity, off-target editing risks, and scalable manufacturing.
