Automated spoken English assessment tests have gained popularity for their well-documented advantages, such as ease of administration and cost efficiency. However, they often focus on single modalities, such as text or audio, and have limited relevance in interactive settings. Now, in a new research study, researchers from the Japan Advanced Institute of Science and Technology have developed a multi-output learning framework that can simultaneously assess multiple aspects of spoken English proficiency.

An overactive immune response can damage the kidneys but also presents a promising target for treatments to slow or prevent disease progression.

A team led by Professor Masakatsu Murakami has developed a novel concept called micronozzle acceleration (MNA). By designing a microtarget with tiny nozzle-like features and irradiating it with ultraintense, ultrashort laser pulses, the team successfully demonstrated—through advanced numerical simulations—the generation of high-quality, GeV-class proton beams: a world-first achievement.

Turbulence—where flows and vortices intricately intertwine—is a fundamental phenomenon found across nature, from our everyday surroundings to the cosmos. In particular, high-temperature fusion plasmas exhibit highly complex turbulence, driven by the coupled fluctuations of multiple physical quantities such as density, temperature, and magnetic fields. A research team led by  Dr Go Yatomi of the National Institute for Fusion Science (a graduate student at SOKENDAI at the time of submission) and Associate Professor Motoki Nakata of Komazawa University (also a visiting researcher at RIKEN) has developed a novel method to analyze turbulent states and interactions from the perspective of "information," drawing inspiration from mathematical frameworks in quantum mechanics, such as information entropy. This approach enables the discovery of previously overlooked turbulence regimes in plasmas and reveals essential nonlinear interactions between multi-scale vortices and flows—interactions that conventional energy-based analyses often miss. The study also proposes potential applications of the method to experimental diagnostics of turbulence and fluctuations. Looking ahead, this technique is expected to extend beyond plasma physics, offering new insights into complex systems in atmospheric and oceanic sciences, as well as in social dynamics, where complex flows and multi-variable interactions also play critical roles.

An Osaka Metropolitan University-led team investigated whether participation in community gathering places reduces the risk of LOI among older adults, including those with mild disability.

Researchers proposed a novel strategy for using a magnetic field to boost the efficiency of single-atom catalysts – thus speeding up helpful reactions used for ammonia production and wastewater treatment.

Understanding the fundamental energy configuration of thermally activated delayed fluorescence (TADF) materials, the key material that make OLEDs, is critical in developing new more advanced OLEDs. However, current analytical methods have been occasionally unreliable due to its inherent subjectivity and conditional assumptions. Now, researchers have developed a new analytical model that details the kinetics and state dynamics of excitons in TADF materials.

Haptophytes—the unicellular photosynthetic marine algae—are one of the major contributors to marine biomass. Scientists at Okayama University, Japan, unveil the first high-resolution structure of the photosystem II–FCPII (photosynthetic supercomplex) in a marine haptophyte, Chrysotila roscoffensis. This discovery sheds light on the unique approach of sunlight capture and energy management by the complex, offering new insights into marine biology and potential advances in artificial photosynthesis technology.

Emerging theories suggest that communication challenges arise from differing perspectives between autistic and non-autistic partners rather than individual socio-cognitive deficits. In addition, while social behavior varies between cultures, observations from Western cultures dominate our understanding of autism. Researchers from Japan and the UK have conducted a cross-cultural analysis comparing the mentalizing performance of British and Japanese autistic and non-autistic adults. Their study highlights the need for more culturally sensitive socio-cognitive measures to assess autistic traits.

A newly identified centromeric structure, the CENP-A–H4 octasome, may reveal how chromosomes segregate properly during cell division, report researchers from Japan. Using cryo-electron microscopy, they visualized this complex formed only of histones CENP-A and H4, wrapped around 120 base pairs of DNA, revealing unique features important for mitosis. These findings may provide a novel perspective for understanding diseases caused by abnormal cell division, including cancer.
