An Osaka Metropolitan University research team observing anemonefish in the field found they engage in interesting feeding behavior with their host sea anemones.

The less carbon dioxide polluting our air, the better. Researchers are investigating non-toxic, low-cost electrocatalysts to turn our sustainability goals into reality.

Tohoku University researchers are looking underfoot to uncover the mysterious past of Mars: Martian regoliths in the soil. Their water storage capabilities may help us understand the change in water on Mars over time.

Osaka Metropolitan University and Osaka University researchers investigated the factors influencing older adults’ acceptance and use of demand-responsive transport (DRT) in Senboku New Town, Osaka. The results revealed a significant relationship between social influence and behavior intention for both older people and adults.

A research team from Nagoya University in Japan demonstrated the “world's smallest shooting game,” a unique nanoscale game inspired by classic arcade games. This achievement was made possible by real-time control of the force fields between nanoparticles using focused electron beams. This research has practical applications, as the manipulation of nanoscale objects could revolutionize biomedical engineering and nanotechnology.

Researchers from Japan and Taiwan reveal for the first time that helium, usually considered chemically inert, can bond with iron under high pressures. They used a laser-heated diamond anvil cell to find this, and the discovery suggests there could be huge amounts of helium in the Earth’s core. This could challenge long-standing ideas about the planet’s internal structure and history, and may even reveal details of the nebula our solar system coalesced from.

Grouting is a widely used construction technique that involves injecting stabilizing materials into soil to ensure structural stability, which is especially beneficial in earthquake-prone regions. Now, scientists from Japan have developed an innovative, carbon-neutral grout made from waste fluids of geothermal energy harvesting systems. Their new material shows a 50% increase in liquefaction resistance compared to conventional grouts, while also addressing environmental concerns associated with the construction industry.

Heteroepitaxial growth technology has made it possible to create larger diamond substrates, opening new opportunities for industrial-scale production of diamond quantum sensors. A research team led by Institute of Science Tokyo in collaboration with Shin-Etsu Chemical Co., Ltd. and the National Institute of Advanced Industrial Science and Technology, successfully fabricated large-area (111)-orientated diamond crystal substrates on heterogeneous (non-diamond) substrates, demonstrating the potential for industrialization of precise, noise-resistant current measurements for electric vehicle battery monitoring.

Gas sensors are essential for personal safety and environmental monitoring, but traditional sensors have limitations in sensitivity and energy efficiency. Now, researchers from Japan have developed an improved gas-sensing technology by treating graphene sheets with plasma under different conditions, creating structural and chemical defects that enhance ammonia detection. These functionalized graphene sheets exhibited superior sensing performance compared to pristine graphene, potentially paving the way for wearable gas detection devices for everyday use.

A new study led by Dr. Yoshinori Takei and Dr. Atsushi Sugiyama of the Department of Pharmacology, Faculty of Medicine, Toho University, along with Dr. Akira Hirasawa of the Graduate School of Pharmaceutical Sciences, Kyoto University, and Dr. Yoko Amagase of the Faculty of Pharmacy, Osaka Medical and Pharmaceutical University, reveals a novel connection between aging of visceral adipose tissue and brain health. These findings were published online on February 13, 2025, in GeroScience, the official journal of the American Aging Association.
