Neurons, the cells in brains and spinal cords that make up the central nervous system, communicate by firing electrical pulses. But scientists have found hints that neurons may transmit light as well, ...

Short pulses from a laser can be twisted into a series of doughnut-like vortices, offering a way to transmit more information using light. We usually encounter vortices in water and air, but similar ...

Forward-looking: Silicon photonics could provide an alternative solution to the growing pains of purely silicon-based chips in computing and data transmission. Light-based CPUs are likely still a long ...
