The Jahn–Teller effect is a well-explored phenomenon in solid-state physics. In a new development, researchers from Waseda University, Japan, focused on spinel-type compounds with the formula AV₂O₄, discovering a phenomenon in which a structural phase transition occurs simultaneously with magnetic ordering in Co₁₋ₓFeₓV₂O₄. This innovation holds fundamental scientific interest and is expected to open new avenues for applications in quantum information.

In fusion research, the plasma core must be heated to about one hundred million degrees, but heat naturally spreads outward, making it important to slow this spreading as much as possible. Turbulence that appears together with the heat also moves outward. A research team at the National Institute for Fusion Science used the Large Helical Device to study this process and identified turbulence that acts as a mediator, rapidly distributing heat across the plasma. When rapid heating was applied, this mediator became stronger and caused the heat to spread almost instantly. The team also showed for the first time that turbulence plays two roles, both carrying heat and connecting distant regions. These findings reveal how sudden heat spreading occurs and provide a basis for predicting and controlling heat transport in future fusion reactors.

At the base of mossy trees, deep in the mountains of Taiwan and mainland Japan or nestled in the subtropical forests of Okinawa, grows what most might mistake for a mushroom – but what is actually a very unique plant with some of the smallest flowers and seeds in the world. With no chlorophyll to photosynthesize with and no root system to supply it with water from the ground, Balanophora has evolved a series of extreme traits to survive entirely as a parasite on the roots of specific trees. Some species and populations produce seeds only without fertilization (obligate agamospermy) – which is exceedingly rare in the plant kingdom. 

Researchers from the Okinawa Institute of Science and Technology (OIST), Kobe University, and the University of Taipei have now joined forces to survey Balanophora across its sparse and inaccessible habitats, upending our understanding of photosynthesis loss in land plants, obligate agamospermy, and the role of the plastids.   

Computer simulations revealed the detailed mechanism of how the protein "dynamin" works to form small vesicles within cells.

While dynamin uses GTP hydrolysis energy to change shape, it was unclear how this leads to membrane constriction. Simulations showed that instead of simply tightening, dynamin "loosens" (expands) at a certain stage to generate the force needed to narrow the surrounding membrane tube.

This study provides a clearer explanation for membrane deformation and vesicle formation processes in cells, offering insights for artificial nano-device design.

Researchers from The University of Osaka have developed a novel reverse genetics system to study norovirus, the leading cause of gastroenteritis. This efficient system can generate infectious viral particles by simply injecting viral genetic material into zebrafish embryos. They were able to alter the genetic material to create modified viruses, enabling the evaluation of antiviral drugs and novel vaccine development. The advances provided by this new system will have a significant effect on public health.

Polydopamine-coated magnetic liposomes offer insight into the lectin–glycan interactions in motion. By observing minute changes in the rotational motion of magnetic nanoparticles under alternating magnetic field, the technique reveals binding patterns, including strong multivalent binding events under natural and physiological conditions. The findings of this study emphasize the role of structure–property relationships, while designing magnetic liposome-based biorecognition systems. This approach could accelerate innovations in diagnostics, glycoscience research, and drug discovery.

Biological supramolecular structures exhibit both lateral and longitudinal interactions, rendering the structure responsive to changes. Thus far, lateral interactions of synthetically assembled supramolecular polymers have only been elucidated. Inspired by microtubules, this study reports cooperative self-assembly of aryl barbiturate molecules into helical coils, driven by the concerted action of noncovalent lateral and longitudinal interactions. These synthetic polymers uniquely alter with changes in temperature. This conceptual advancement will influence future material designs of next-generation polymers.
