A research team led by Dr. Masaki Arata and Professor Toshihiko Fujimori at Japan’s National Institute for Basic Biology investigated how longitudinal oviduct epithelial folds affect oocyte transport. Using mutant mice with disrupted fold architecture due to reduced VANGL1 protein, they discovered that directional ciliary beating remained largely intact, and the mice remained fertile. Tracking fluorescent beads revealed that transport in mutants was slower and less direct. The findings demonstrate that while longitudinal folds of the oviduct are not strictly essential for moving eggs to the uterus, they serve to optimize transport speed, stability, and overall efficiency.
Researchers from the University of Osaka, Gunma University and Kyushu University created lipid mimic molecules that form “island”-like groups called lipid domains in artificial lipid membranes. The domains are thermally stable because the propellor-shaped moiety of the lipid mimic molecules interlock and the surrounding lipids fit into the spaces between. This new method of forming domains may allow artificial lipid membrane materials to be created for catalysis, capturing molecules, and drug delivery.
A research team has revealed that THIK-1, a two-pore domain K+ (K2P) channel expressed in immune cells, including brain microglia and systemic macrophages, is inhibited by a steroid 17β-estradiol, a key female sex hormone. The researchers also found that a human THIK-1 genetic variant is sensitive to the hormone at low, naturally occurring physiological concentrations, showing a 12% reduction in activity.
A research team led by Professor Hitoshi Yamamoto of Rissho University analyzed five years of longitudinal panel survey data collected between 2020 and 2024 and examined how vaccine-related conspiracy beliefs were associated with media skepticism during the COVID-19 pandemic. The study's results appeared in Scientific Reports on August 8, 2026.
A highly integrated phased-array wireless integrated circuit developed at Institute of Science Tokyo, Japan, enables 144 Gbps dual-polarized multiple-input multiple-output (MIMO) communication in the 150 GHz sub-terahertz band, bringing practical 6G devices a step closer to reality. By developing a highly integrated phased-array transceiver with a significantly smaller circuit footprint, the research paves the way for future applications such as immersive extended reality and remote healthcare services.
In hub-filament systems, radially converging filaments are known to channel dense gas into hubs where massive stars form, but the contribution of inter-filamentary diffuse gas has remained unclear. In this study, researchers mapped gas motions in the Monoceros R2 star-forming region using carbon monoxide observations. They found that diffuse inter-filamentary gas not only flows directly toward the central hub but also replenishes dense filaments, substantially increasing the total gas reservoir available for massive star formation.
