Korean researchers have developed, for the first time in Korea, a 200Gbps-class photodetector device that can be used in hyperscale AI data centers and 5G/6G mobile communications infrastructure. This technology enables ultrahigh-speed data reception at a level capable of transmitting five 5GB full HD movies per second. Electronics and Telecommunications Research Institute (ETRI) announced that it has developed a photodetector device capable of processing 200Gbps-class optical signals per channel. A photodetector is a key semiconductor component that converts optical signals into electrical signals and is an essential element that determines data reception performance in data centers and communication networks.

Prof. Yingxiang Liu's team at the State Key Laboratory of Robotics and Systems, Harbin Institute of Technology, developed a unique tripodal piezoelectric robot driven by a high-stiffness ring-shaped elastic body. By combining axisymmetric vibration modes with an asymmetric foot arrangement, the proposed robot achieves both planar agile motions and high load capacity.

A new study published in Big Earth Data proposes a large language model (LLM)-based multi-agent framework for remote sensing analysis that integrates data resources, analytical tools, and AI-driven reasoning to assist non-expert users in conducting complex remote sensing tasks. Using the ExpertsRS prototype built on AutoGen and DeepSeek-V3, experiments demonstrate that the system can transform ambiguous queries into expert-level analytical workflows and outperform baseline LLM and single-agent approaches in planning efficiency and result accuracy. The Sentinel-2 dataset used in this study is openly available from the European Space Agency at https://www.esa.int/Applications/Observing_the_Earth/Copernicus/Sentinel-2. The code repository for this work is accessible at https://github.com/zhelunSun/URSA.

Mississippi State scientists are building on two decades of irrigation research to identify production practices that help growers save water while improving crop yields.

Lewis-paired dopants are a promising way to achieve strong, stable doping in organic semiconductors, but their high reactivity makes precise control over doping levels difficult. In a recent study, researchers from Korea tackled this issue by showing that solvent polarity can regulate dopant reactivity during processing. Using this new strategy, they achieved finely tunable, efficient, and stable doping across multiple organic semiconductors, supporting the development of next-generation flexible and sustainable organic electronics.

Ada by Antoine Bello delves into the meaning of creativity in the context of AI through its protagonist Ada, an AI character who writes literary works. In a new article, a researcher from Pusan National University has analyzed the novel to bring out the meaning and forms of creativity by leveraging the perspectives of powerful thinkers, including Walter Benjamin, Henri Bergson, and Jacques Derrida.

Imagine a paint that changes color depending on how hard its surface is hit. It could be used on football helmets to monitor concussion-level impacts, to record the handling history of shipped packages, or placed on insoles to analyze an orthopedic patient’s gait.
