Researchers at The University of Osaka have developed an improved technique called “tapping-mode scanning probe electrospray ionization” (t-SPESI), allowing the analysis of regions within individual cells with greater sensitivity and stability.

Researchers at the Nano Life Science Institute (WPI-NanoLSI) at Kanazawa University, Institute for Molecular Science and SOKENDAI have uncovered the hidden mechanism behind a molecular switch—a molecule that can change between different structural states in response to a chemical signal. Their study, published in the Journal of the American Chemical Society, reveals how molecules can gradually switch between alternative states, a process that could help scientists design future molecular machines, smart materials, and molecular information technologies. To make the discovery, Shigehisa Akine and colleagues created a specially designed molecular cage that changes shape unusually slowly. This allowed them to observe, for the first time, the sequence of molecular events that occurs after the molecule receives a chemical input. The study provides one of the clearest views yet of how molecular recognition triggers structural change and demonstrates that the response speed of a molecular system can itself be engineered through molecular design.

Researchers break a fundamental rule to create a new concept: heat that can be directed and “programmed”. In most materials, heat absorption and heat emission are linked, meaning a surface that absorbs thermal radiation well from a particular direction will also emit it in the same way. A team from OMU in Japan has designed a reconfigurable device that breaks this symmetry, enabling heat to be absorbed and emitted differently depending on the direction of absorption. This technology could eventually lead to smarter thermal-management systems and infrared sensors.

Researchers at the University of Osaka developed a light-driven method for synthesizing Davis reagents that generates the hazardous oxidant mCPBA only on demand and consumes it immediately. Kinetic analysis showed no detectable accumulation of the oxidant, improving process safety. The reaction proceeds at room temperature in non-halogenated solvents and can use sunlight or LEDs, offering a safer, greener, and scalable alternative for pharmaceutical-related synthesis.

Hiroshima University researchers have demonstrated a proof of concept for the mass-production of genome-edited T cells that can be used to treat malignant tumors, using a genetic engineering technique called Platinum TALEN.

Researchers at the University of Osaka have used machine learning to develop a systematic framework for structural descriptors in supercooled water. A neural network model was used to quantitatively assess the performance of 16 structural descriptors in differentiating between two states of water, a high-density liquid and a low-density liquid. The framework could be used to further our understanding of the anomalous behavior of water.

Researchers from the University of Osaka found that the human brain represents social relationships learned through drama viewing, especially antagonistic ties. Participants watched six episodes of SUITS and underwent fMRI scans before and after viewing. Brain activity patterns after viewing reflected rivalries and conflicts among characters, particularly in regions involved in social cognition. The findings suggest that negative relationships help structure the brain’s internal social maps.

Researchers at Tohoku University have discovered a promising strategy that converts harmful carbon dioxide into valuable fuels and chemicals by precisely altering nanoclusters made of copper.

The abundance of sulfur not only makes lithium-sulfur batteries cheaper to manufacture, but they also boast superior energy-storage capacity to current lithium-ion technologies. But one problem preventing practical deployment is polysulfide shuttling—when polysulfides formed during battery cycling escape the cathode and drift into unwanted areas and cause the battery to erode. Now, a group of researchers from Tohoku University has solved this problem with a molecularly designed covalent organic framework (COF)–graphene interlayer. Like a security checkpoint that both identifies threats and efficiently streams people where they need to go, the interlayer combines chemical trapping, rapid charge transport, and sulfur-conversion promotion.

Magnets can store data – but there is a limit. To improve the data density of memory devices, researchers at Tohoku University delved into ways to exert precise control over a unique material called metallic helimagnets.

Researchers at National Taiwan University and the University of Southern Denmark show that obesity in male mice raises let-7 microRNAs in sperm, which silence the enzyme DICER1 and impair mitochondrial function in the fat tissue of their offspring. Weight loss reverses part of the effect in both mice and men.

A research team from City University of Hong Kong (CityUHK) has recently overcome a technological bottleneck that has persisted for over a decade.

Oxidative addition is often carried out using transition metals and is challenging to perform at centers of more abundant main-group elements, particularly group 13 elements. Researchers at The University of Osaka, led by Takuya Kodama, achieved oxidative addition of an aryl iodide to a group 13 (gallium) center. The reaction is initiated by visible light. The reaction proceeds via a novel mechanism, photoinduced disproportionation, whereby photoexcited gallium exchanges electrons with ground-state gallium.

Black-box optimization, particularly Bayesian optimization, is a practical approach for weather-intervention design, achieving meaningful rainfall reduction even under a very limited budget of expensive weather simulations, finding effective actions with only a small number of trials.

Researchers at the University of Osaka have synergistically combined three strategies for energy dissipation to enhance the toughness of elastomers. Rotaxane molecules with sacrificial bonds are incorporated into an elastomer. Under increasing external force, three mechanisms become sequentially activated: sliding of the rotaxane molecules, force-induced bond scission in the rings to form linear chains, and entanglement of the resulting chains. A polyurethane elastomer synthesized using this strategy was five times tougher than a conventional polyurethane.

A field experiment with the Japan Marrow Donor Program showed that adding one factual sentence to HLA match letters—telling potential donors that compatible registered donors are limited—raised progression to confirmatory typing by 7.3%. The intervention was low-cost and simple, while combined messages weakened the effect. The result could help reduce donor dropout and improve stem cell transplant coordination.
