A research team comprising members from the National Institute for Materials Science (NIMS), Tohoku University, and the Photon Science Innovation Center (PhoSIC) has successfully identified the optimal composition of a Co-Mn-Si Heusler alloy exhibiting the highest spin polarization—a key property of half-metallic materials—in just one day of experiments. This achievement was made possible by fabricating a composition-spread thin film on a single substrate and conducting photoelectron measurements at a 3 GeV high-brilliance synchrotron radiation facility, NanoTerasu. This highly efficient optimization approach is expected to accelerate the development of high-performance spintronic materials.

Scientists have identified a simple, noninvasive method for assessing blood glucose regulation using continuous glucose monitoring (CGM) data. Their approach, which tracks glucose fluctuations, outperforms traditional markers in predicting diabetes risk. To expand accessibility, they have developed a web application for easy calculation of CGM-based indices.

Researchers at Tohoku University explored a colloidal crystal model to produce specific polymorphs, required for use in materials science and pharmaceuticals.

Researchers have developed a light-induced DNA detection method that enables rapid, PCR-free genetic analysis. Their technique offers ultra-sensitive mutation detection in just five minutes, reducing costs and simplifying testing. The method has significant potential in healthcare, environmental conservation, and personal health monitoring.

Ultrasound imaging is one of the most widely used diagnostic tools in modern medicine. Behind its non-invasive magic lies a class of materials known as piezoelectric single crystals, which can convert electrical signals into mechanical vibrations and vice versa. Now, in a world-first, a research team from Kumamoto University has successfully visualized how tiny structures inside one of these crystals respond to electric fields in real time—shedding light on the dynamics of nanostructure in materials used in ultrasound probes.

A NIMS research team has developed an approach capable of accurately and  short-timeframe predicting the degradation behavior of electrocatalysts used in water electrolyzers by employing data assimilation—a method commonly employed in weather forecasting. After analyzing only 300 hours of experimental data, this approach accurately predicted the degradation of an electrocatalytic material occurring after approximately 900 hours of water electrolysis. This approach is able to accelerate and simplify the comparison of degradation properties among various electrocatalytic materials, potentially facilitating investigations into their degradation mechanisms and expediting the development of more efficient, economical and durable electrocatalytic materials.

Okinawa and its surrounding waters represent what marine biologists call a "shark and ray hotspot" in terms of both diversity and conservation significance. In this episode of the OIST podcast, Dr. Fabienne Ziadi-Künzli, a marine biologist and shark researcher at the Okinawa Institute of Science and Technology (OIST), explained that this region creates unique habitats for sharks throughout their different life stages.

Researchers at Osaka Metropolitan University investigated the effect of demand-responsive transport (DRT) on residents’ average daily steps.

Tokyo, Japan – Researchers from Tokyo Metropolitan University have found that the motion of unlabeled cells can be used to tell whether they are cancerous or healthy. They observed malignant fibrosarcoma cells and healthy fibroblasts on a dish and found that tracking and analysis of their paths can be used to differentiate them with up to 94% accuracy. Beyond diagnosis, their technique may also shed light on cell motility related functions, like tissue healing.
