Scientists have demonstrated that negative refraction can be achieved using atomic arrays -- without the need for artificially manufactured metamaterials. Scientists have long sought to control light ...

The pressure exerted on a surface when it is struck by light is tiny, but it is enough to move very small objects. Shigeki Matsuo and co-workers at the University of Tokushima and the Nara Institute ...

QIScope: When imaging low protein levels in live cells on the high-sensitivity QIScope, bioluminescence (blue) significantly outperforms fluorescence (green). (Courtesy: Ruyu Ma - Helmholtz Munich) A ...

ELECTRON micrographs may be considered analogous to X-ray pictures, since the darkness and brightness depend on the thickness and density of the specimen; they are unlike micrographs taken with the ...
