Inside the spinal cord of a zebrafish embryo, new neurons light up in different colors, letting scientists track nerve circuit development. ...

In principle WERS offers a solution to the inherent issue of low sensitivity to which Raman spectroscopy is prone. Rather than employing free-space optical components, WERS incorporates Raman spectroscopy into a waveguide structure, allowing the waveguide to transport incident light,...

Smart glass technology that starts opaque but turns transparent when filled with index-matching fluid....

Technique would allow addition of optical communication components to existing chips with little modification of their designs....

The Fraunhofer Institute for Laser Technology (ILT), based in Aachen, Germany, has developed a new ablative process for the ultra-precise machining of aspherical optics. Aspheres offer numerous advantages to optical designers, however the mechanical processing required to manufacture them is...

An imaging technique that builds on Bessel beam based light-sheet microscopy and Airy beam based light-sheet microscopy could result in less intrusive and more effective diagnosis for patients. The new method, published in Science Advances, allows light to be shaped so it can reach...

To better understand how proteins move and interact within a cell membrane, an imaging method called live-cell single fluorescent-molecule imaging (SFMI) can be used to tag each protein in the membrane with a fluorescent marker....

Simultaneous imaging and energy harvesting achieved in new design of "self-powering" CMOS image sensor pixels....

University of Illinois researchers, using a camera inspired by the polarization-sensitive eyes of mantis shrimp, have collected subsea information that could lead to a new form of underwater GPS....

With novel optoelectronic chips and a new partnership with a top silicon-chip manufacturer, MIT spinout Ayar Labs aims to increase speed and reduce energy consumption in computing, starting with data centers. Backed by years of research at MIT and elsewhere,...
