Mutated optic rod photoreceptors have been reprogrammed, using the gene-editing tool CRISPR/Cas9, reversing cellular degeneration and restoring visual function in two mouse models of retinitis pigmentosa. The study was done by researchers at University of California San Diego School of Medicine and Shiley Eye Institute at UC San Diego Health, with colleagues in China. Retinitis… Read more

A new technique which delivers light deeper into human tissue than previously possible has been developed by researchers at the University of St Andrews and Harvard Medical School. The new method, published in the journal Nature Communications, could help heal wounds faster and treat tumors more efficiently. Through a process called photochemical tissue bonding, light… Read more

The theory of resonance fluorescence, a classic phenomenon in quantum optics, has been extended to 2D nanostructures that have novel light emission properties. The research, from physicists at the University of Southampton, has potential applications in photonics devices that are based on the optical properties of quantum wells. Resonance fluorescence is fluorescence from an atom… Read more

Invention of the first integrated circularly polarized light detector on a silicon chip opens the door for development of small, portable sensors that could expand the use of polarized light for drug screening, surveillance, optical communications and quantum computing, among other potential applications. The new detector was developed by a team of Vanderbilt University engineers… Read more

The tiny ocean creatures known as sea sapphires perform a sort of magic trick as they swim- one second they appear in iridescent shades of blue, purple or green, and the next they may turn invisible (at least the blue ones turn completely transparent). How do they get their bright colors and what enables them… Read more
