Innovations in microscopy and imaging technologies are pushing the boundaries of biological research and diagnostics. Developments include a chip-based, label-free super-resolution microscopy technique, confocal squared spinning-disk image scanning microscopy for high-fidelity tissue imaging, and gated single-photon camera fluorescence lifetime imaging for single molecules. Ultrafast optical metasurface switching and neuromorphic Hebbian learning with magnetic tunnel synapses further exemplify progress in the photonics and computational imaging fields, enabling deeper understanding of cellular dynamics and neural processes.
