The position of biomineralization peptides within liposomes can influence how gold nanoparticles grow, reports a research team from Institute of Science Tokyo. Peptides localized at the membrane interface promote branched structures, while those confined to the liposome interior favor spherical nanoparticles. The findings offer a new strategy for controlling nanoscale reaction environments in nanoparticle synthesis.

A new Review in Trends in Genetics revisits the chromosome scaffold model and integrates recent findings on condensins, topoisomerase IIα, and physical forces that shape mitotic chromosomes. The authors propose that pre-existing condensed chromatin domains in interphase nuclei may serve as dynamic “building blocks” that are gathered, crosslinked, and reorganized during mitosis, linking chromosome-associated proteins with the physical properties of chromatin.

Okayama University of Science has teamed up with the 1,100-year-old Okayama Shrine to create a unique goshuin, a traditional Japanese shrine seal, featuring Tarbosaurus, one of Asia’s largest carnivorous dinosaurs. Scientifically supervised by the university’s Department of Dinosaur Paleontology, the collaboration brings together dinosaur research and Japanese tradition while encouraging visitors to discover Okayama’s growing connection to dinosaurs.

Researchers developed a zebrafish–Yersinia ruckeri model to quantify how pathogen levels, exposure time and Far-UVC irradiation shape infection outcomes. As illustrated in the figure, the cumulative exposure parameter Λ combines pathogen level and exposure time and marks a critical boundary for infection control. Far-UVC can shift the system below this boundary by reducing viable pathogens. This quantitative framework may guide smarter infection-control strategies for crowded indoor spaces and strengthen preparedness for future pandemics.

Tokyo, Japan – Researchers from Tokyo Metropolitan University have identified how certain dangerous bacteria are spread. They studied chain-like adherence pattern (CLAP) varieties of Shiga toxin-producing E. coli (STEC), finding that single bacteria attach to a surface and elongate before dividing, producing chains without ever separating. Under flow, chain ends which are torn off can attach elsewhere, dispersing the strain. They identified a new gene family mediating CLAP formation, illuminating new aspects of infection mechanisms and potential treatments.

Roughly one-third of the food produced worldwide is wasted, and researchers at Kyushu University are turning to packaging for a solution. Their review brings together intelligent sensing materials, self-healing films, and AI-driven prediction to expand packaging's role from passive protection to active, real-time sensing. Through a closed loop of recognition, judgment, actuation, and feedback, the team aims to make packaging a trusted, responsive part throughout the food system, from producers to consumers.

Metal and dielectric nanostructures have traditionally offered different optical advantages, but combining both functions usually requires complex hybrid designs. Now, researchers demonstrate that a single MoOCl₂ nanostructure can independently support metallic and dielectric resonance modes controlled by orthogonal light polarizations. The two nonhybrid modes coexist without crosstalk, enabling precise light manipulation and opening new opportunities for compact photonic devices, optical communication, sensing, and multifunctional metasurfaces for future integrated photonic technologies and devices. 

Chemical bonding can strongly influence the structure and electronic properties of transition-metal materials. In layered vanadium chalcogenide (Li₀.₅VS₂) electron-deficient bonding configurations reorganize from zigzag-chain networks to a more localized dimer-like states as temperature goes down. It also exhibits a magnetic state crossover, while retaining metallic conductivity. The findings highlight electron-deficient bonding as an emergent electronic degree of freedom and provide a framework for understanding competing electronic states in correlated materials. 

Kyocera Corporation and Tohoku University have developed a new technology that integrates optical isolators directly onto silicon photonics chips using laser annealing. Building on their previous collaboration, the two organizations will continue working toward commercialization and more efficient, sustainable information technologies.
