Hydrogen can store renewable energy, but then what stores the hydrogen? A new AI-powered, logic-based method provides probable materials for the job – and explains the reasoning behind its decision.

The study discovered that soil pH is a key factor in regulating the symbiotic relationship between pests and soil bacteria.

Researchers at the University of Osaka found that direct survey questions may overstate negative attitudes toward the news media in Japan. In two web-based randomized experiments, 45.1% of respondents agreed that “the mass media are harmful to society” when asked directly, compared with an indirect estimate of 29.7% from a list experiment. The findings suggest that, where media criticism is easy to express, direct questions may inflate anti-media sentiment.

Magnetic fields are generally known to destroy superconductivity in a material. However, in exceptional cases they can lead to what is known as “reentrant superconductivity”— where superconductivity disappears as expected but then unexpectedly returns when the magnetic field is increased further. This behavior is sometimes seen in bulk, three-dimensional materials, but now, researcher have seen the phenomenon in a very thin conducting layer at the boundary between two insulating oxide materials.

Pollinators are commonly classified into functional groups based on similarities in morphology and behavior, under the assumption that such groupings reflect comparable contributions to plant reproduction. Researchers at University of Tsukuba challenge this conventional assumption by analyzing pollen carried on insect bodies. The team found that even among morphologically similar pollinators differed substantialy in both the types and composition of pollen they transported. These differences suggest considerable variation in floral fidelity—the tendency to repeatedly visit specific plant species—and may also affect the potential for heterospecific pollen transfer (HPT).

New experimental evidence demonstrates that discrete space-time crystals can be realized in classical soft-matter systems, thereby moving beyond the traditional complexities of quantum mechanics.

A tandem neural network capable of inferring key physical parameters of semiconductor materials from simple transistor measurements has been developed, as reported by researchers from Institute of Science Tokyo. While conventional approaches for this type of analysis require hours or even days, the proposed system produces results in under one millisecond with near-perfect accuracy.

CADASIL, an inherited disease caused by mutations in the NOTCH3 gene, damages the brain’s small blood vessels, leading to strokes, cognitive decline, and early dementia. Despite decades of research, its underlying disease mechanisms remain poorly understood due to the lack of suitable disease models. To tackle this issue, researchers have developed the world’s first zebrafish model of CADASIL, which reproduces several key features of the disease. Their findings will help identify potential therapeutic targets. 

Sjögren disease, an autoimmune disease characterized by dry mouth and dry eyes, may reduce patients’ quality of life. While CD4⁺ T cells are key drivers of immune-mediated tissue damage and chronic inflammation, the role of pathogenic CD4⁺ T cell subsets and their non-immune cell partners remains unexplored. Researchers have now identified the preferential CD4⁺ T cell-fibroblast cellular interaction that amplifies inflammatory proteins and tissue damage, representing a potential target for therapeutic intervention in Sjögren disease.

According to the Times Higher Education Sustainability Impact Rankings 2026, released on June 24, Hokkaido University ranks 7th globally and has maintained 1st place in Japan for the seventh consecutive year.
