DOUGLAS FARMER, SENIOR EDITOR [email protected]An exploration into quantum effects produced in nanoscale biological processes has the potential to upend traditional perceptions of the causes and effects of Alzheimer’s disease and other neurological conditions. Researchers have discovered that when tryptophan, an amino acid that is a fundamental building block of certain proteins, collects in a structural network within neural fibers, it can collect harmful ultraviolet light and release it at biologically safe intensities. The scientists at the Quantum Biology Laboratory at Howard University have focused their recent...Read full articleRelated content from Photonics MediaArticlesPhotoacoustic Microscopy Method Delivers Higher SensitivityA multispectral, super-low-dose photoacoustic microscopy (SLD-PAM) system developed by City University of Hong Kong (CUHK) achieves significantly higher sensitivity than traditional optical...BioPhotonics Nov/Dec 2023 IssueWavefront Shaping Improves Tissue Imaging for Disease DetectionWavefront shaping is used to reverse the optical distortion caused by Earth’s atmosphere and provide clear images of distant planets.
