A research paper by scientists at The Chinese University of Hong Kong proposed a 3D radar-based control scheme that realizes the navigated locomotion of microswimmers in 3D space with multiple static and dynamic obstacles. The new research paper, published on Jun. 2 in the journal Cyborg and Bionic Systems, presented a 3D hierarchical radar with a motion sphere and a detection sphere is firstly developed. Using the radar-based avoidance approach, the desired motion direction for the microswimmer to avoid obstacles can be obtained, and the coarse-to-fine search is used to decrease the computational load of the algorithm. Three navigation modes of the microswimmer in 3D space with dynamic conditions are realized by the radar-based navigation strategy that combines the global path planning algorithm and the radar-based avoidance approach.

Severe weather events, such as heavy rainfall, are becoming increasingly commonare on the rise worldwide. Reliable assessments of these events can save lives and protect property. Researchers at the Karlsruhe Institute of Technology (KIT) have presented developed a new method that uses artificial intelligence (AI) to convert low-resolution global weather data into high-resolution precipitation maps. The method is fast, efficient, and independent of location. Their findings have been published in npj Climate and Atmospheric Science: https://doi.org/10.1038/s41612-025-01103-y 

CZI announced its latest AI model, GREmLN, aimed at helping researchers better understand how cells behave by focusing on the key networks that control cell behavior.

Researchers from Seoul National University (Prof. Seung-Kyun Kang), the Korea Institute of Science and Technology, KIST (Dr. Hyojin Lee), Kwangwoon University (Prof. Jeonghyun Kim), and Gyeongsang National University (Prof. Seongchan Kim) have developed a wireless implantable drug delivery system that enables anticancer drugs to penetrate deep into solid tumors—without harming surrounding healthy tissue. The multidisciplinary team, led by experts in materials science, bioelectronics, and pharmaceutical engineering, offers a new strategy to enhance the efficacy of chemotherapy while minimizing side effects.
