Summary: Energy-dependent changes in single nucleotide polymorphisms (SNPs) in microribonucleic acids (microRNAs/miRNAs) were linked from femotosecond blasts of UV light to DNA repair via an extremely sensitive assay for the label-free optical detection and suppression of interfering effects caused by non-specific binding. Interactions in Augmented and Mixed Reality: An Overview 9/20/21 (This article belongs to the Special Issue Extended Reality: From Theory to Applications) All interactions are energy-dependent and microRNA-mediated. ~250 newly indexed articles attest to that fact, which is…
