Protein designers have now created new calcium channels, built bottom-up from scratch. Naturally occurring ion channels, present in the membrane of excitable cells, generate electrical impulses. These electrophysiological signals help direct muscle contraction, the heartbeat and the release of neurotransmitters. Synthetic ion channels could serve as tools for biomedical research, from neuroscience experiments to heart biology models and synthetic cell signaling circuits.
The Japan Science and Technology Agency (JST) will hold the 4th Japan-India Universities Forum in India on November 15, 2025. In the event, we will focus on promoting Japan-India brain circulation and utilization of its human resources in the fields of science, technology, and innovation. Participants from 37 universities and research institutes and related organizations, and 11 business corporations in Japan and 35 universities and research institutes in India will be gathered.
A joint research team from POSTECH, Eunpyeong St. Mary’s Hospital, and Hankuk University of Foreign Studies has developed a 3D-bioprinted retina-on-a-chip and retinal vein occlusion model.
A new method developed at the University of Warwick offers the first simple and predictive way to calculate how irregularly shaped nanoparticles — a dangerous class of airborne pollutant — move through air.
The Korea Research Institute of Standards and Science (KRISS, President Lee Ho Seong) has developed an artificial intelligence (AI)-based image segmentation algorithm that can rapidly reconstruct three-dimensional (3D) structures from two-dimensional (2D) cross-sectional images of biological samples captured using a scanning electron microscope (SEM).
