Novel DNA-based assemblies for the development of remote-controlled microsystems

Institute of Science Tokyo
Peer-Reviewed Publication

Remote-controlled microflow using light-controlled state transitions within DNA condensates has been reported by scientists from Institute of Science Tokyo, Japan. By switching between ultraviolet light (UV) and visible light irradiation, the researchers demonstrated that the novel DNA motifs containing azobenzene can dissociate or reassemble. Furthermore, localized photo-switching within a DNA liquid condensate generated two distinct directional motions. This study can fuel the development of innovative fluid-based diagnostic chips and molecular computers.

Which legume crop rotation pattern better promotes soil health?

Higher Education Press
Peer-Reviewed Publication

A team led by Prof. Zhenke Zhu from Ningbo University analyzed 261 soil samples across China to systematically compare the impacts of different legume crop rotations on soil properties and microbial communities, revealing the unique advantages of faba bean (Vicia faba) rotation in enhancing soil multifunctionality and its microbial-driven mechanisms. The relevant paper has been published in Frontiers of Agricultural Science and Engineering (DOI: 10.15302/J-FASE-2025604).
