Using catalytic chemistry, researchers at Institute of Science Tokyo have achieved dynamic control of artificial membranes, enabling life-like membrane behavior. By employing an artificial metalloenzyme that performs a ring-closing metathesis reaction, the team induced the disappearance of phase-separated domains as well as membrane division in artificial membranes, imitating the dynamic behavior of natural biological membranes. This transformative research marks a milestone in synthetic cell technologies, paving the way for innovative therapeutic breakthroughs.

Slow earthquakes have been discovered to exhibit anomalously slow, long-lasting, and small slips, adjacent to regular earthquakes where we sometimes feel catastrophic vibration. However, no one knows the reason why they show such strange characteristics. In a study published in a scientific journal Nature Communications, researchers at The University of Osaka succeeded in experimentally reproducing the multiple features of slow earthquakes in the lab and suggested the grain-scale origin of them based on their direct observations.

01 December 2025 / Kiel. A study by an international team involving the GEOMAR Helmholtz Centre for Ocean Research Kiel shows that the expansion of Antarctic Bottom Water during a major warming phase around 12,000 years ago displaced a carbon-rich mass of deep-water in the Atlantic sector of the Southern Ocean. This process released carbon dioxide that had been stored in the deep ocean, thereby contributing to the end of the last Ice Age. The study provides important insights into how the ocean may respond as Antarctica continues to warm today. The findings are published today in Nature Geoscience.

Inspired by snake pit organs, we propose a CMOS-integrated upconverter system achieving room-temperature, 4K ultra-high-resolution short-wave and mid-wave infrared imaging. Utilizing colloidal quantum dot barrier heterojunctions and co-hosted emitting units, the device demonstrates superior luminance and upconversion efficiency. This innovation breaks visible light limitations, advancing applications in night vision, agriculture, and industrial inspection.
