Preschool teachers shape young children’s development, but how their expertise evolves remains less understood. Using video-cued ethnographic interviews, a researcher studied 112 preschool educators across Japan, China, and the United States to explore what drives professional growth. The study revealed cultural differences in mentoring, collaboration, and motivation. These findings led to a new framework for understanding how early childhood teachers change, offering insight into improving teacher development across diverse educational systems.

With climate change exacerbating drought conditions, scientists in Japan have identified a hidden player in plant survival: myosin XI. This unexpected link between the motor protein and hormone signalling that regulates water loss deepens our understanding of plant stress responses. It also opens a promising avenue for engineering drought-resilient crops. Targeting myosin XI could enhance water-use efficiency and help reshape the future of agriculture in an increasingly arid world.

Using a high-throughput fluorescence microscopy system and machine learning algorithms, oxidative stress-related changes in protein localization have been mapped by researchers from Japan. Furthermore, a comprehensive database called Localizatome has been developed by compiling the subcellular protein localization data of 10,287 human proteins. This database provides information on both the steady-state subcellular localization of proteins and dynamic localization changes that occur in response to oxidative stress.

Researchers at The University of Osaka have developed a novel framework for measuring occupancy in open-plan offices with unprecedented precision.  This innovative system uses computer vision and AI to analyze occupancy at a micro-scale level, focusing on specific functional zones within the office.  This addresses a significant gap in current occupancy tracking methods, which typically only provide macro-level data and struggle to capture detailed usage patterns within shared spaces.

As the days grow shorter, many animals prepare for the approaching winter by suspending reproduction. Insects, for example, accumulate energy stores while halting ovarian development through a process known as reproductive diapause. In a recent study published in The Journal of Experimental Biology, researchers at The University of Osaka uncovered a key neuroendocrine pathway underlying this seasonal shift in the bean bug Riptortus pedestris, identifying the neuropeptide corazonin as a molecular signal that suppresses reproduction in response to changes in day length.

Kyoto, Japan -- Experts say quantum computing is the future of computers. Unlike conventional computers, quantum computers leverage the properties of quantum physics such as superposition and interference, theoretically outperforming current equipment to an exponential degree.

When a quantum computer is able to solve a problem unfeasible for current technologies, this is called the quantum advantage. However, this edge is not guaranteed for all calculations, raising fundamental questions regarding the conditions under which such an advantage exists. While previous studies have proposed various sufficient conditions for quantum advantage, the necessity of these conditions has remained unclear.

Motivated by this uncertainty, a team of researchers at Kyoto University has endeavored to understand the necessary and sufficient conditions for quantum advantage, using an approach combining techniques from quantum computing and cryptography, the science of coding information securely.

A fossil discovered in a rock on display at the Nariwa Museum of Art in Takahashi City, Okayama Prefecture, has been identified as Japan’s first Late Triassic ichthyosaur and the first ichthyosaur ever found in western Japan. The find was made by Professor Takafumi Kato and colleagues during a museum-based educational event. CT scans revealed 21 bone fragments, including vertebrae and a scapula, confirming the fossil’s identity. Experts say the discovery offers rare and valuable insight into the evolution and distribution of ichthyosaurs during the Norian stage, when open-ocean species emerged. The fossil is now on public display and is expected to inspire local education and scientific interest.
