Dynamic nanogates let longer molecules pass faster through flexible pores
Dynamic nanogates let longer molecules pass faster through flexible pores Stephanie Baum Scientific Editor Robert Egan Associate Editor A research team led by Professor Shuichi Hiraoka at the University of Tokyo and Professor Masanori Tachikawa at Yokohama City University has quantitatively analyzed how molecules pass through dynamic nanoscale pores using self-assembled molecular "nanocubes" in water. The researchers discovered an unexpected phenomenon: For linear alkane molecules, longer...
Tiny X-ray telescope could unlock the Moon's hidden chemistry
Tiny X-ray telescope could unlock the Moon's hidden chemistry A tiny new X-ray telescope could unlock the Moon’s hidden chemistry and finally reveal how our nearest neighbor evolved. - Date: - June 6, 2026 - Source: - Tokyo Metropolitan University - Summary: - A lightweight new X-ray telescope could finally give scientists something they’ve never had before: a complete chemical map of the Moon.
Lunar orbiter concept could reveal five key elements across moon in two years
Lunar orbiter concept could reveal five key elements across moon in two years Andrew Zinin Lead Editor 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 lunar 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...
Printed manga may give the brain a storytelling advantage
Printed manga may give the brain a storytelling advantage Robert Egan Associate Editor A new study by researchers at the University of Tokyo explores whether reading manga on paper or on a tablet changes how the brain understands and remembers stories. Participants first read the opening half of a two-part manga story either on paper or on a tablet. Later, while inside an MRI scanner, they read the second half through LCD goggles and answered questions about the story.
Real-time data assimilation system outperforms flood early warning system
Researchers at the Institute of Industrial Science, the University of Tokyo (UTokyo-IIS), have developed a real-time data assimilation system that substantially improves streamflow and flood forecasting accuracy across Japan. This new data assimilation system outperforms Japan's current early warning system. Compared with the previous early warning system, the new data assimilation system yields improved forecasts for 80% of the major river reaches in Japan and enables reliable flood...
Ultrathin nanotubes reach 1 nanometer, opening path to smaller electronics
Researchers in Japan have created some of the world's smallest semiconducting nanotubes, structures 100,000 times thinner than a human hair. By growing molybdenum disulfide inside protective tubes of boron nitride, the researchers, including those from the University of Tokyo, produced highly uniform tubes just 1 nanometer wide, a scale at which it's difficult to make stable nanotube structures. The work confirms decades-old theoretical predictions about how these ultrafine materials behave...
Why plant cells need heme: Hidden signal reshapes photosynthesis gene control
Why plant cells need heme: Hidden signal reshapes photosynthesis gene control Sadie Harley Scientific Editor Andrew Zinin Lead Editor For plants, light is an important environmental factor not only as a source of energy for photosynthesis, but also as a signal for capturing environmental information. Light signals are sensed by photoreceptor proteins called phytochromes. The amino acids that make up proteins are transparent and cannot absorb visible light.
Bacteria uncover distinct strategy to import rare sugar polymers, crystal structures show
Bacteria uncover distinct strategy to import rare sugar polymers, crystal structures show Sadie Harley Scientific Editor Andrew Zinin Lead Editor Even though sugars are often framed as simple sources of energy, they also serve as structurally complex and functionally diverse molecules that mediate interactions between organisms. Among these, β-1,2-glucans, which are a class of glucose-based polymers, stand out for their varied and sometimes subtle roles. Found across a wide range of...
Redesigning an elusive bacterial enzyme into an efficient green catalyst
Redesigning an elusive bacterial enzyme into an efficient green catalyst Sadie Harley Scientific Editor Robert Egan Associate Editor Industrial oxidation chemistry is a cornerstone of modern manufacturing, accounting for nearly one-third of all chemical industrial processes. While essential for making pharmaceuticals, dyes, and many specialty chemicals, industrial oxidation typically relies on high-temperature, high-pressure processes involving toxic oxidizing agents. This has motivated...
Japan's new seafloor record could sharpen megathrust earthquake warnings in Nankai Trough
Japan's new seafloor record could sharpen megathrust earthquake warnings in Nankai Trough Sadie Harley Scientific Editor Robert Egan Associate Editor Off the southern coast of Japan, the Philippine Sea Plate lies underneath the Japanese mainland. The locked tectonic plates threaten to unleash a catastrophic megathrust earthquake, likely within the next few decades. Given the potential devastation a large quake could evoke, constant developments in predictive technology must be sought.
