A study on calcium bioavailability by researchers with the Arkansas Agricultural Experiment Station show that two calcium availability tests — a classic approach and a newer, speedier test — offer reliable results that can help poultry producers optimize calcium digestibility.

For the first time in the world, a joint research team from NIMS, Nagoya University and The University of Tokyo has successfully observed the transverse Thomson effect—a phenomenon in which metals or semiconductors release or absorb heat when a heat current, charge current and magnetic field are applied orthogonally to each other. This achievement may contribute to advances in physics and materials science related to the conversion between heat, electricity and magnetism, as well as to the development of new thermal management technologies. The research was published in Nature Physics on June 26, 2025.

Using Lego Mindstorms EV3, researchers from Kyushu University have developed a new 3D bioprinting method that can customize the texture, adhesiveness, and water retention of protein-based emulsion gels for dysphagia diets using controlled radiofrequency and microwave energy.

Elusive low-energy constant determined from fundamental theory

Potassium- and calcium-modified ilmenite oxygen carriers, developed by Institute of Science Tokyo, significantly improve hydrogen yields and redox reaction efficiency in chemical looping systems. The chemical modification of ilmenite results in the formation of a calcium titanate phase with iron substitution. This advancement enhances the oxide ion diffusion, accelerates hydrogen production, and also enables a polygeneration system for simultaneous hydrogen production, carbon dioxide capture, and power generation—paving the way to scalable, carbon-neutral energy systems.

Researchers at Soochow University have conducted a comprehensive electrokinetic study on cation-coupled electrochemical CO₂ reduction to formic acid or formate. Published in Science Bulletin, the study provides compelling experimental evidence that supports existing computational predictions: the reaction proceeds through sequential electron and proton transfers, rather than a concerted proton-coupled electron transfer pathway.

A research team from Zhengzhou University has systematically sort out the mechanistic frameworks and theoretical underpinnings of triboelectric nanogenerators (TENGs), concurrently introducing four cutting-edge application frontiers: fluid energy harvesting, self-adaptive sensors and systems, high-voltage power sources, and interface probes. Beyond dissecting persistent technological bottlenecks, this review establishes actionable development trajectories to steer next-generation advancements.
