A multidimensional chemical mapping strategy enables confident determination of the structures of non-coding RNAs at 1-nm resolution, including previously intractable riboswitch and human regulon states.
Fundamental details of the rate and molecular spectrum of transcript errors were revealed in four bacterial species, providing novel insights into transcriptional fidelity and RNA quality-control in prokaryotes.
The first genomic view of beetle luciferase evolution indicates evolutionary independence of luciferase between fireflies and click-beetles, and provide valuable datasets which will accelerate the discovery of new biotechnological tools.
Heterotypic immunity, the ability of immunity induced by one SARS-CoV-2 variant to protect against another, is asymmetric, with the UK (B.1.1.7) variant, eliciting weaker heterotypic immunity than other variants.
Activity-regulated genes in Drosophila neurons differ from the well-characterized situation in mammals, and these genes provided a strategy to construct reporters for monitoring neuronal activity in fly brains.
