3-D imaging provides window into living cells, no dye required
(Phys.org) —Living cells are ready for their close-ups, thanks to a new imaging technique that needs no dyes or other chemicals, yet renders high-resolution, three-dimensional, quantitative imagery of cells ...
Researchers create on-chip interference between pairs of photon sources
Novel X-ray device developed
Using a compact but powerful laser, a research team at the University of Nebraska-Lincoln has developed a new way to generate synchrotron X-rays.
Tiny lasers light up future electronics
(Phys.org) —Faster, smaller electronics are one step closer with researchers from The Australian National University successfully making the first room temperature lasers from gallium arsenide nanowires.
Plasmonic crystal alters to match light-frequency source
Gems are known for the beauty of the light that passes through them. But it is the fixed atomic arrangements of these crystals that determine the light frequencies permitted passage.
Light-activated medical implants: Team develops light-guiding hydrogel for cell-based sensing
Topological light: Living on the edge
(Phys.org) —Topology—the understanding of how things are connected—remains abstract, even with the popular example of doughnuts and coffee cups. This concept, esoteric as it appears, is also neat because ...
New material gives visible light an infinite wavelength
Researchers from the FOM Institute AMOLF and the University of Pennsylvania have fabricated a material which gives visible light a nearly infinite wavelength. The new metamaterial is made by stacking silver ...
