Optical lattice clocks are emerging timekeeping devices based on tens of thousands of ultracold atoms trapped in an optical lattice (i.e., a grid of laser light). By oscillating between two distinct quantum states at a particular ...
Macrophages drive key immune processes including inflammation, tissue repair, and tumorigenesis via distinct polarization states whose accurate identification is vital for diagnosis and immunotherapy. However, methods like ...
