In multicore optical fibers, a key research question was whether low-power and high-power laser pulses would distribute light differently among seven cores. Researchers from Russia found that low power gave random, unstable distribution, whereas higher power produced equal sharing across all cores and stability against bending and vibrations. The far-field pattern changed from speckled to bell-shaped. Modeling showed a statistical mechanism, where the pulse broke into many sub-pulses whose averaging produced stable equalization.

Small flapping-wing (FW) robots could support applications such as inspection and search and rescue. However, they are highly susceptible to disturbances such as wind gusts, making stable flight challenging. Researchers from Chiba University investigated the flight dynamics of a commercial FW robot and discovered a behavior that limits how quickly its control system can correct disturbances. They developed a control method that accounts for this limitation, helping the robot achieve more stable and accurate flight.

As part of the plans to build a fusion reactor in Germany, the Federal Government is establishing new research hubs. The Karlsruhe Institute of Technology (KIT) will play a significant role in this effort: KIT researchers are developing key technologies for the fuel cycle, high-performance materials, and essential reactor components. By contributing its broad expertise, KIT helps turn fusion technology into a practical reality and plays a leading role in advancing it from fundamental research to real-world application.

A new technology has been developed that can produce ammonia—an essential carrier for storing and transporting clean hydrogen energy—more efficiently.
