Sometimes the simplest solution is the best one. This research shows how exposing a single active site has huge implications for producing green energy.

Probabilistic computers can solve certain problems more efficiently than traditional computers, but are usually saddled with a power-hungry, bulky, analog component. That is, until a research team developed a fully digital p-bit 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.

Listening to the "whispers" of electrons and crystals has lead to a quantum discovery with terahertz light that could help us advance technological innovations and life science research.

Researchers from The University of Osaka found migration of glucose and fructose from the blood to saliva drives oral microbiome dysbiosis in patients with type 2 diabetes, increasing the development of dental caries. This suggests that glycemic control could be an effective strategy for controlling dental caries in this population.

Elastic fiber component level in human hepatic stellate cells may predict liver damage

Rechargeable batteries get a supercharged boost from newly developed RAMOFs that don’t break down in water, which was previously a major problem for this material.

Researchers at the Nano Life Science Institute (WPI-NanoLSI), Kanazawa University, report in ACS Nano the successful creation of artificial synaptic vesicles that can be remotely controlled by near-infrared (NIR) light. By embedding a phthalocyanine dye into lipid bilayers, the team achieved local heating that modulates membrane permeability, enabling precise release of neurotransmitters such as acetylcholine. These findings demonstrate that nanoscale heating can control communication between nerve cells. The work opens new avenues for non-genetic modulation of neuronal activity, with potential applications in neuroscience, drug delivery, and bioengineering.

Researchers at the Nano Life Science Institute (WPI-NanoLSI), Kanazawa University, have developed a breakthrough method for quantitative imaging of ATP levels inside living cells. The study, published in Nature Communications, introduces qMaLioffG, a genetically encoded fluorescence lifetime indicator that allows scientists to observe how cells produce and consume energy in real time.

Sonochemical degradation of carbon tetrachloride was found to increase in the presence of alcohols

Slow earthquakes have been discovered to exhibit anomalously slow, long-lasting, and small slips, adjacent to regular earthquakes where we sometimes feel catastrophic vibration. However, no one knows the reason why they show such strange characteristics. In a study published in a scientific journal Nature Communications, researchers at The University of Osaka succeeded in experimentally reproducing the multiple features of slow earthquakes in the lab and suggested the grain-scale origin of them based on their direct observations.

Researchers from The University of Osaka created a reagent for important building-block molecules with an abundant main-group element, gallium. These early findings show that an organic gallium compound can display transition-metal-like reactivity under light irradiation. Using common main-group elements like gallium offers a new way to make sustainable catalysts that do not need expensive transition metals, which are environmentally damaging and vulnerable to supply disruption.

A research group led by Associate Professor Islam MD Parvez and Professor Kenji Hato of the Graduate School of Agriculture at Ehime University has developed "Hort-YOLO," a real-time monitoring system for horticultural crops. This system is an advanced object detection network focused on accurate and context-aware analysis of crops, and simultaneously achieves a balance between annotation speed and scalability of supervised learning, making it practical for deployment in real-world environments.

Researchers from The University of Osaka developed mirror-image semiconductor polymer molecules for organic solar cells. The new acceptor molecules prevent recombination of electrons and holes by generating currents with spin-polarization of about 70% in which one electron spin dominates. Solar cells containing the new acceptors showed three times higher efficiency than the non-mirror-image version. Using mirror-image acceptor molecules provides a new way of increasing efficiency in clean energy technology.

A commoning approach for democratic, community-centric weather modification

Researchers from The University of Osaka fabricated a nanopore surrounded by a gate as a cooling system with enhanced efficiency for semiconductor chips. Applying a voltage to the gate induces the flow of ions through the nanopore. Creating a salt gradient makes the ion flow unidirectional. Heat is dragged along with the ions, resulting in heat transfer. Changing the applied voltage from negative to positive switches the system from cooling to heating.

Researchers from Japan have unveiled a comprehensive dataset detailing the psychological and social responses of Japanese adults to the COVID-19 pandemic. Spanning 30 survey waves from January 2020 to March 2024, the open dataset captures how Japanese adults’ risk perception, preventive behaviors, policy attitudes, views toward foreigners, and psychological distress evolved over more than four years of uncertainty. Published as a data paper in Data in Brief, this resource is now openly accessible to the global community.

Superconductive materials can conduct electricity with no resistance, but typically only at very low temperatures. Realizing superconductivity at room temperature could enable advanced, energy-efficient electronics and other technologies. Now, an international research team is one step closer to such an achievement.

Scientists at the Nano Life Science Institute (WPI-NanoLSI), Kanazawa University, have discovered how a gene-regulating protein forms tiny liquid-like droplets inside the cell nucleus (the compartment that stores and manages DNA) to guard against cancer. Their study, published in Nature Communications, shows that these protein droplets act as control centers that keep tumor-suppressor genes switched on.

Physicists at The University of Osaka have unveiled a breakthrough theoretical framework that uncovers the hidden physical rule behind one of the most powerful compression methods in laser fusion science — the stacked-shock implosion. While multi-shock ignition has recently proven its effectiveness in major laser facilities worldwide, this new study identifies the underlying law that governs such implosions, expressed in an elegant and compact analytic form.

Astronomers have uncovered a previously unknown, extreme kind of star factory by taking the temperature of a distant galaxy using the ALMA telescope. The galaxy is glowing intensely in superheated cosmic dust while forming stars 180 times faster than our own Milky Way. The discovery indicates how galaxies could have grown quickly when the universe was very young, solving a long-standing puzzle for astronomers.
