21+ hour, 10+ min ago   (534+ words) Researchers at the University of Toronto and the University of Saskatchewan have engineered a compact, far-red light-responsive protein pair that could redefine how scientists switch molecules on and off inside living cells. The new system, described in Nature Methods, pairs…...

1+ day, 2+ hour ago   (73+ words) Light passing through a carefully engineered nanostructure can behave in ways that ordinary optics never allows. It can cancel itself out at certain frequencies, reinforce itself at others, and produce sharply asymmetric spectral lines that seem to defy the smooth,…...

2+ day, 13+ hour ago   (184+ words) Researchers at Wuhan University developed a molecular-sieve-assisted confined molten-salt route to grow 2.66 nm Na2Nb4O11 single-crystal sheets. Devices made from the material combined sensitive ultraviolet detection with millisecond response and stable cycling, and enabled UV imaging and proof-of-concept two-wavelength physical-layer information encoding....
