Scientists found that certain chemical impurities, such as hydrogen and oxygen, help amorphous carbon form graphite-like, ultralow-friction interfaces under mechanical stress. The findings reveal how impurities can enable self-forming lubricating surfaces, offering a new strategy for designing durable, energy-efficient materials.

Researchers at the University of Waterloo have developed a lightweight, flexible polymer material that could replace lead in X-ray aprons while providing comparable protection from harmful radiation. By incorporating specially engineered tungsten nanoparticles into a silicone-based nanocomposite, the team created a shielding material that is nearly 90 per cent lighter than traditional lead aprons, potentially reducing the back and neck injuries commonly experienced by health-care workers who wear them for extended periods.

Researchers at The University of Osaka have developed novel kirigami structures with periodic parallel inclined cuts. Stretching these materials longitudinally causes them to twist and rotate. Thus, these structures provide a mechanism for coupling tension and rotation. The mechanical deformation of these structures can be characterized in terms of a geometrical property, the chirality. Some of the developed chiral structures were auxetic, longitudinal stretching resulting in lateral expansion, instead of contraction. The findings have applications in soft robotics and soft actuators.

Practical utility demonstrated through three-step scale-up synthesis of the antidiabetic drug sitagliptin

Professor Akihiro Kaneko of Okayama University of Science has achieved international recognition for a second consecutive year at Kura Master, a prestigious Japanese sake competition held in France. “Aldebaran,” a red wine produced from Muscat Bailey A grapes grown in Ibara, Okayama Prefecture, under Professor Kaneko’s supervision, received a Gold Award in the Muscat Bailey A category. The award highlights ongoing efforts to preserve a historic local grape variety whose cultivation has declined in recent years. In addition, “Junmai -eme-,” a sake brewed using yeast isolated from Muscat of Alexandria grapes by Professor Kaneko and his research team, earned the competition’s highest distinction, the Platinum Award, in the Junmai Sake category. The awards demonstrate the growing international impact of research and innovation in viticulture and enology at Okayama University of Science.

A research team has uncovered a previously unknown RNA-based control system that helps tea plants regulate amino acid production, a process central to tea flavor, nutritional value, and quality. 

Tokyo, Japan – Researchers from Tokyo Metropolitan University have used simulations to show that a newly developed, compact X-ray telescope could be used to map the chemical composition of the entire Moon surface, a vital breakthrough for understanding its geological evolution. Detailed modeling of the detector and a realistic satellite mission show that two years would be enough to map five key elements, while an array of five-by-five detectors could improve resolution and get results faster.

As the planet warms, soils may release more nitrous oxide, a powerful greenhouse gas linked to agriculture, fertilizer use, and microbial nitrogen cycling. A new study published in Biochar shows that biochar, a carbon-rich material made by heating biomass with limited oxygen, can change how strongly soil nitrous oxide emissions respond to rising temperatures. But the effect is not one-size-fits-all.

Jaspreet Singh Randhawa, a Mississippi State assistant professor of physics, has received a prestigious CAREER Award from the National Science Foundation to support a $700,000 research project on the nuclear reactions that power stellar explosions and other extreme cosmic events.
