A new dual-light microscope lets researchers observe micro- and nanoscale activity inside living cells without using dyes. The system captures both detailed structures and tiny moving particles at ...

Three years after a team of Caltech scientists showed that pairs of entangled photons could double the resolution of a light microscope, the same lab has figured out a way to double down on that ...

Three years after a group of Caltech researchers demonstrated that pairs of entangled photons could quadruple a light ...

Overcoming the resolution limit in a light microscope of around half a wavelength of light (about 250 nanometers) is one of the most significant developments in optics. Due to the wave nature of light ...
