Glass ceilings can prevent women from advancing in organizational hierarchies, but glass fences may also be limiting — especially to Japanese female faculty who must navigate strong cultural gender expectations, according to a new study.
Researchers have developed nanodiamond sensors with nitrogen-vacancy (NV) centers, offering exceptional brightness and spin properties for quantum sensing and bioimaging. These nanodiamonds outperform commercial options, requiring 20 times less energy and maintaining quantum states 11 times longer. Enhanced sensitivity to magnetic fields and temperature enables precise applications, including disease detection, battery analysis, and thermal management of electronics, marking a significant advancement in nanotechnology-driven quantum sensing for biological and industrial innovations.
Researchers at Tohoku University's AIMR have developed a new Li-O₂ battery cathode using free-standing graphene mesosponge (GMS) sheets, which eliminates the need for vulnerable binders. This design improves oxygen and Li-ion flow, enhancing stability and performance. The team demonstrated significant capacity and stable cycling, with plans to focus on Li metal anodes for further improvements.
Even highly realistic androids can cause unease when their facial expressions lack emotional consistency. Traditionally, a "patchwork method" has been used for facial movements, but it comes with practical limitations. A team developed a new technology using "waveform movements" to create real-time, complex expressions without unnatural transitions. This system reflects internal states, enhancing emotional communication between robots and humans, potentially making androids feel more humanlike.
A new bird deterrent system, "Bird Sonic," is being trialed at Kansai International, Itami, and Kobe airports to enhance flight safety. Developed by Professor Masachika Tsuji of Okayama University of Science and T.M. WORKS, the system uses high-frequency sound waves to repel birds from runways.
Installed on March 1, the device targets species like snipe and lark with adjustable frequencies and diverse sound patterns. With 49 bird strikes reported in FY2023, the one-year trial aims for 80–90% effectiveness, offering a safer and more efficient alternative to traditional methods.
Tokyo, Japan – Researchers from Tokyo Metropolitan University have discovered that around 15 days of dry weather can trigger the flowering of durian. Observations of 110 durian plants revealed that flowering occurred around 50 days after an approximately 15-day dry spell, independent of whether the plant was grafted or grown from a seed. The team’s work might not only impact the production of a valuable agricultural asset but deepen our understanding of tropical ecosystems.
Heterogeneity in host populations significantly influences pathogen evolution, yet most theories assume uniformity. This study uses a meta-population model to examine how local environmental heterogeneity—factors like migration, birth, carrying capacity, and immunity loss—affects pathogen virulence. The findings reveal that greater heterogeneity consistently results in higher virulence compared to homogeneous environments. These results suggest that previous models underestimated evolving virulence, raising concerns that urbanization and increasing environmental diversity may accelerate the emergence of more lethal pathogens.Heterogeneity in host populations significantly influences pathogen evolution, yet most theories assume uniformity.
