Researchers from the Institute of Industrial Science, The University of Tokyo, have created a specially designed “bottlebrush” polymer that was used to produce a reaction space the size of a single molecule. This space acted as a nanoscale vessel to allow new materials, such as specialty polymers, to be created under highly controlled conditions. The technology has applications in advanced technologies such as drug delivery and remote sensing.  

A Japanese research team has successfully achieved direct observation of the charge distribution at the interface of ferroelectric domains. This nanometer-scale distribution was measured using a combination of advanced local charge imaging with a state-of-the-art electron microscope and atomic displacement analysis at the picometer (one trillionth of a meter) scale.

These findings represent a significant breakthrough in understanding the behavior of ferroelectric devices—such as multilayer ceramic capacitors (MLCCs)—which are increasingly in demand for miniaturization and enhanced performance.

 Researchers from The University of Osaka found that both inhibitory and activating killer immunoglobulin-like receptors on natural killer (NK) cells were able to bind repetitive interspersed family proteins expressed on the surface of malaria-infected red blood cells. The role of these proteins in triggering both inhibitory and stimulatory responses from NK cells makes them extremely promising targets for the development of therapies and vaccines for malaria.

The National Institute of Information and Communications Technology (NICT) the Advanced ICT Research Institute, ASTRODESIGN, Inc. , and Fujikura Ltd. have developed a multi-core fiber cable consisting of eight 4-core, standard cladding diameter multi-core fibers, and they have successfully implemented it for the first time as an ultrahigh-capacity data transmission unit in a real system handling uncompressed 8K video.

In an uncompressed 8K video system, approximately 70 Gbps of data must be transmitted per video stream, requiring one single-core single-mode fiber for each uncompressed 8K camera. The developed multi-core fiber cable contains a total of eight standard cladding diameter (125 μm) single-mode 4-core multi-core fibers of two different types within a 3 mm diameter cable, which is equivalent to the 32 single-core single-mode fibers that are conventionally used in uncompressed 8K video systems.

In this implementation, by introducing a transmission unit that utilizes the multi-core fiber cable, we successfully achieved stable system operation by transmitting high-volume video data from multiple 8K cameras installed in a cleanroom, through limited-capacity information conduits and building interior spaces, over 300 m to an 8K video composition device located in a separate building.

This achievement enables the deployment of systems requiring high-capacity data transmission, such as uncompressed 8K video systems, even in cases in which conventional installation was difficult owing to limited space in information conduits or wiring pathways within or between buildings.

Osaka Metropolitan University researchers identified REDD2, a stress-responsive gene that damages insulin-producing pancreatic β-cells under metabolic stress. By disrupting insulin secretion, REDD2 contributes to the onset of type 2 diabetes. Suppressing this gene in mice helped preserve β-cell function and improve glucose control, offering a potential target for early diabetes intervention.

Signs of planet formation may appear earlier than expected around still-forming baby stars, according to new results of higher resolution images produced using new improved techniques to reanalyze radio astronomy archive data. These newly discovered signs of planet formation will provide a better understanding of when it begins around a young star, thereby elucidating the process that leads to planet formation, including habitable planets like Earth.

Atoms slip against one another, eventually sticking in various combinations. Tectonic plates do the same, sliding across each other until they stick in a stationary state. Everything from the tiniest particles to unfathomably large landmasses possesses this fundamental stick and slip characteristic, but only now are scientists beginning to understand the mechanics of the friction underpinning this property.

In joint research with The University of Tokyo (UTokyo) and Nagoya University, National Institute for Materials Science (NIMS) developed a new material "thermoelectric permanent magnet" exhibiting extremely high transverse thermoelectric conversion performance, and achieved transverse thermoelectric generation with a power density of 56.7 mW/cm² around room temperature in a thermoelectric-permanent-magnet-based module. When converted into a value per applied temperature gradient, this is not only the world’s highest power density among transverse thermoelectric modules, but a performance even comparable to commercial longitudinal thermoelectric modules. This achievement is expected to lead to thermal energy harvesting and management technologies that can be utilized everywhere magnets are used. This research result was published in Energy & Environmental Science on March 18, 2025.
