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.

Two cutting-edge research projects at Bar-Ilan University have been awarded Proof of Concept (PoC) Grants from the European Research Council (ERC)—a major achievement that highlights the university’s interdisciplinary leadership in both biomedical science and AI-driven public policy.

We need to make our energy system more sustainable – but what is the best way to achieve this? In order to plan the energy supply of the future, policymakers need sound facts and figures. Science already provides reliable models for comparing the sustainability and the costs of different energy systems. Now, Empa researchers have also developed a model for calculating supply security.

The public, legislators, and media often group per- and polyfluoroalkyl substances, known as PFAS or “forever chemicals,” which are found globally in countless products, into a single category. While certain PFAS are harmful for human and public health, new articles in Heart Rhythm, the official journal of the Heart Rhythm Society, the Cardiac Electrophysiology Society, and the Pediatric & Congenital Electrophysiology Society, published by Elsevier, emphasize that fluoropolymers, a specific class of PFAS, are not considered environmental contaminants and are indispensable for use in medical devices. Experts call for a balanced approach to protect both the environment and availability of essential medical technologies.
