Researchers from the Japan Advanced Institute of Science and Technology (JAIST) and the University of Tokyo have designed bioinspired hydrogels capable of using sunlight to produce hydrogen and oxygen from water. Hydrogels contain polymer networks that facilitate energy conversion, offering a breakthrough approach to generating renewable hydrogen energy. This research shows how polymer-based systems could revolutionize sustainable energy production.

Osaka Metropolitan University researchers have found that administering the dried seeds of a type of jujube called Ziziphus jujuba Miller var. spinosa, used as a medicinal herb in traditional Chinese medicine, holds promise in restoring cognitive and motor function in model mice.

Sodium-containing transition-metal layered oxides are promising electrode materials for sodium-ion batteries, a potential alternative to lithium-ion batteries. However, the vast number of possible elemental compositions for their electrodes makes identifying optimal compositions challenging. In a recent study, researchers from Japan leveraged extensive experimental data and machine learning to predict the optimal composition of sodium-ion batteries. Their approach could help reduce time and resources needed during exploratory research, speeding up the transition to renewable energy.

Studying synapses in live human brains is crucial for understanding many psychiatric disorders. Now, using positron emission tomography of the brain of patients with psychiatric disorders, researchers from Japan have developed and used a novel technology to visualize the distribution of AMPA receptors, one of the most important molecules in synaptic transmission. Their efforts could lead to more accurate diagnosis and targeted treatments for diseases like schizophrenia, bipolar disorder, and autism spectrum disorder.

Hydrogen, a promising fuel, has extensive applications in many sectors. However, its safe and widespread use necessitates reliable sensing methods. While tunable diode laser absorption spectroscopy (TDLAS) has proved to be an effective gas sensing method, detecting hydrogen using TDLAS is difficult due to its weak light absorption property in the infrared region. Addressing this issue, researchers developed an innovative calibration-free technique that significantly enhances the accuracy and detection limits for sensing hydrogen using TDLAS.

 Plesiosaurs once roamed Earth’s waters, using four equal flippers to propel their elongated bodies through the water. Fossils from these Mesozoic marine reptiles do not preserve the muscle tissue needed to explain how they maneuvered. Yet a group of researchers have harnessed a bio-inspired control system, creating a plesiosaur-like robot that reveals key insights into how they once traversed the oceans. The model could be used in the future to shed light on the movement of other extinct animals.

Hydrogen's potential as a promising future energy source is increasingly recognized. However, safely transporting large quantities of hydrogen gas remains a notable challenge. Researchers from University of Tsukuba have addressed this issue by developing a durable, poison-resistant non-noble metal anode that can potentially replace the expensive metal electrodes currently used in organic hydride electrolytic synthesis. This method allows the handling of hydrogen as a liquid energy carrier.

Researchers from Osaka University found that Highly Sensitive Persons (HSPs) in the workplace experience significantly higher levels of stress compared to their non-HSP colleagues. Approximately 26% of working adults could be classified as HSPs, indicating that a substantial portion of the workforce might be experiencing higher levels of stress. Interestingly, HSPs also exhibit greater empathy, suggesting that their heightened sensitivity enables them to connect deeply with others, potentially fostering a more supportive work environment.
