A review paper by scientists from Beijing Institute of Technology reviewed the theoretical foundations, key technologies, innovative applications, and future challenges of autonomous robots in precise drug delivery, a field with revolutionary potential.

The new research paper, published on Jun. 29 in the journal Cyborg and Bionic Systems, provided a hierarchical, function‑oriented framework that directly links microrobot design to the progressive physiological barriers encountered in vivo, from accessible body cavities to the most challenging immune‑privileged sites.

A recent study uncovers the most comprehensive explanation to date for the unprecedented Arctic ozone event of March 2024, revealing new insights into the complex connections between tropical variability, atmospheric wave dynamics and polar ozone in a warming world.

With the long-term on-orbit operation of the China Space Station, using nanosatellite swarms for cooperative observation of its external structures has become an important technical direction for enhancing in‑orbit monitoring capabilities. However, the space station itself has a non‑spherical complex geometry (e.g., protruding structures such as modules and docking ports) and may perform attitude maneuvers (e.g., sun‑pointing) during orbital flight, making it a dynamic obstacle with both intricate shape and rotational motion relative to the nanosatellites. Traditional artificial potential field obstacle avoidance methods mostly simplify obstacles as spheres or ellipsoids, which cannot accurately characterize the composite geometric features of the space station, and usually ignore the obstacle's own rotational motion. This leads to difficulties in constructing the repulsive potential field, limited maneuvering space, and, more critically, a lack of rigorous theoretical proof to guarantee closed-loop system stability and collision avoidance. Therefore, developing a nanosatellite formation control method that can handle rotating non‑spherical obstacles while providing strict stability guarantees is of significant theoretical importance and engineering value for ensuring safe fly-around and efficient cooperative observation in the vicinity of the space station.

To address the long-standing trade-off between high uniformity and system complexity in conventional lithographic illumination, a team led by Academician Shaohua Yu at Peng Cheng Laboratory and Prof. Zizheng Cao at Zhejiang University proposes a fundamentally new solution: a lensless monitoring and uniform lithographic illumination system based on asymmetric diffusion metasurfaces.

The present study develops a taste bud organoid-based biosensor using a 3-dimensional microelectrode array to systematically investigate the modulatory effects of caffeine on various taste perceptions.
