Transmission light microscopy is any optical microscopy technique that relies on detection of light from the opposite side of the sample that was illuminated.
Living snakes replace their teeth without external resorption. Here, the authors use histology to show that odontoclasts resorb dentine internally and investigate this mechanism in fossil snakes.
The authors present a planar photonic chip, which operate as a multiple-order analog spatial differentiator. It provides a route for designing fast, power-efficient, compact and low-cost devices used in edge detection and optical image processing, thus expanding the functions of standard microscopes.
Multi-colour light fields allow a nonlinear coupling between free electrons and propagating light by stimulated Compton scattering, without the need for near fields to mediate the interaction.
