Researchers have demonstrated the world’s first simultaneous generation of 3,070 optical vortices at megawatt-class peak power (58 MW). By reformulating Hermite–Gaussian to Laguerre–Gaussian mode conversion and implementing it through a compact multibeam interference architecture, the team achieved more than three orders of magnitude improvement in both vortex number and peak power. The work establishes a scalable framework for high-intensity structured-light generation.

Butterfly wings were the inspiration behind this new, lightweight lattice structure that doesn’t compromise on sturdiness.

Researchers at The University of Osaka developed an eight-week training program that teaches CBT by encouraging graduate students to apply CBT techniques to their own experiences and reflect on the process. In a preliminary study of 29 trainees, the program showed high satisfaction, low adverse events, and perceived benefits in CBT understanding, self-awareness, and reflective skills. The approach may provide a promising new model for training mental health professionals.

Skepticism about claims regarding sustainability reduces consumers’ intentions to purchase sustainable products by weakening two important drivers of green consumption: people’s willingness to look for trustworthy environmental information and their anticipated guilt about making less sustainable choices.

Researchers investigated how the η′ meson behaves inside atomic nuclei and found evidence that it may form bound states known as η′-mesic nuclei. Using high-energy particle experiments and sophisticated data analysis, the team observed signals consistent with theoretical predictions and measured a possible change in the particle’s mass in nuclear matter. These findings provide new insight into the structure of the vacuum and the origin of mass.

A joint research team between the Center for Quantum Information and Quantum Biology (QIQB) at The University of Osaka and Fixstars Corporation has demonstrated one of the world's largest classical simulations of iterative quantum phase estimation (IQPE) quantum circuits for quantum chemistry on up to 1,024 GPUs, surpassing the previous 40-qubit limit. The result expands the scale of molecular systems available for the development and validation of quantum algorithms for future fault-tolerant quantum computers, supporting progress toward industrial applications in drug discovery and materials development.

Free-electron lasers can be tuned to operate over a wide range of wavelengths, but they conventionally require large-scale facilities. Researchers from The University of Osaka show that laser wakefield acceleration can dramatically miniaturize this technology by improving plasma stability and electron beam quality. Their study demonstrates such lasers in the extreme ultraviolet, with the ultimate goal of further refining the technology to operate at x-ray wavelengths.

Researchers identified the tegmentum in the midbrain as an ‘integration center’ of fish. The area receives visual information from the eyes that is combined with color information detected by the pineal organ—the ‘third eye.’ These inputs are integrated to control how fish orient themselves in the water.

Hiroshima University researchers have developed a practical framework to identify candidate pathogenic variants hidden among the large number of variants of uncertain significance (VUS) detected in comprehensive genomic profiling (CGP) of cancers. This framework could improve the accuracy of precision oncology by more reliable prioritization of VUS.

Assessing the Impact of Chemical Contaminants on Finless Porpoises Using In Vitro Data and Mass Distribution Modeling

Fujitsu Limited and the Center for Quantum Information and Quantum Biology at The University of Osaka today announced the development of a new technology designed to accelerate the industrial application of quantum computers in the era of early fault-tolerant quantum computing (early-FTQC). By combining ver. 3 of the STAR architecture, a unique highly efficient phase rotation gate quantum computing architecture, with a novel molecular model optimization technique, researchers have significantly reduced computational resource requirements. This breakthrough will enable the energy calculations for chemical material design such as catalyst molecules, within a realistic timeframe using early-FTQC quantum computers. These kinds of calculations are currently not possible using current computers, and would take millennia even using previous versions of the STAR architecture. The technologies are expected to contribute to solving various societal challenges, including accelerating drug discovery, improving the efficiency of ammonia synthesis processes, and advancing carbon recycling technologies.

Researchers from The University of Osaka found that leukemia caused by NUTM1 rearrangements is distinguished from other forms of B-cell acute lymphoblastic leukemia (B-ALL) by a unique pattern of gene activity and gene regulation. Unlike the common form of B-ALL caused by KMT2A rearrangement, which is resistant to treatment, leukemic cells with NUTM1 rearrangements are highly sensitivity to chemotherapy.
