A nanoscale optical device has been developed that allows independent control over the intensity and phase of light. By applying voltage, this innovative device can freely manipulate the phase and ...

Light-intensity walking reduces postprandial glucose and diastolic blood pressure in young adults with obesity and can improve insulin levels, depending on the walking pattern. Researchers conducted a ...

Researchers in Hong Kong and the UK have revealed how one species of self-propelling microbes can actively change the path of their swimming motions, depending on how much light they receive.

Scientists in China have developed a metasurface platform that realizes true three-dimensional (3D) vectorial holography by ...
