An international study published in Nature Climate Change reveals that vast regions of the global ocean are experiencing compound state change, with simultaneously warming, becoming saltier or fresher, losing oxygen, and acidifying—clear indicators of climate change pushing marine environments into uncharted territory.

Image scanning microscopy based on multifocal metalens for sub-diffraction-limited imaging of brain organoids

Super-resolution imaging is essential for visualizing fine biological structures beyond the diffraction limit. To advance this field, Scientists in Korea developed a super-resolution imaging system based on a novel multifocal metalens. This ultrathin metalens generates dense, uniform focal arrays optimized for image scanning microscopy (ISM), achieving twice the resolution of conventional wide-field (WF) imaging. The technique successfully revealed fine neuronal structures in brain organoids and is expected to open new avenues for advanced optical microscopy systems.
