Researchers at Rice University have unveiled groundbreaking insights into magnetism and electronic interactions within advanced materials, potentially revolutionizing fields like quantum computing and high-temperature superconductors. Their study of iron-tin (FeSn) thin films has shifted the understanding of kagome magnets, which are structured in a pattern inspired by traditional Japanese basket weaving. The team discovered that FeSn’s magnetic properties are driven by localized electrons, rather than the previously believed mobile electrons—a revelation that could alter how scientists approach materials in quantum technology.

Despite these advancements, challenges remain in observing magnetic splitting at higher temperatures in kagome magnets. However, in a key development, the team was able to create high-quality FeSn thin films and analyze their electronic structure using a combination of molecular beam epitaxy and angle-resolved photoemission spectroscopy. Their findings showed that the kagome flat bands remained split even at elevated temperatures, a sign that localized electrons drive the material’s magnetic properties. This discovery underscores the complex role electron correlation plays in shaping magnetic behaviors in kagome structures.

Japanese scientists have successfully created hybrid cells that combine animal and plant traits, allowing animal cells to produce energy from sunlight through photosynthesis. This novel approach, led by researchers at the University of Tokyo, could have transformative implications for creating lab-grown tissues, organs for transplants, and even cultivated meat.

In living organisms, animal cells rely on mitochondria to convert chemical energy from food into usable energy. Plant cells, however, use chloroplasts to perform photosynthesis, converting sunlight into cellular energy. In this study, the team introduced chloroplasts from red algae into cultured hamster cells, enabling them to perform photosynthesis—a feat previously achieved only in yeast, a fungus, but never before in animal cells.

Researchers at Princeton University’s School of Engineering have looked to nature—specifically, birds—to enhance flight safety and efficiency in aircraft. Inspired by the covert feathers birds use for precise maneuvers, the team has designed multi-row flaps that deploy automatically to prevent aircraft from stalling.

Birds rely on covert feathers during complex aerial movements, like landing in high winds, to improve control and stability. While engineers have long used single-row flaps in aircraft to improve lift, they haven’t explored multi-row configurations that mimic how birds manage airflow in response to environmental changes. Assistant Professor Aimy Wissa and her team focused on the aerodynamics of deploying multiple rows of flaps and how this design could improve flight performance.
