New x-ray microscopy technique could help accelerate efforts to map neural circuits

One of the grand quests in neuroscience is to build a precise map of the brain, charting all its neurons and the connections between them. Such a wiring diagram, called a connectome, promises to help shed light on how a collection of cells can together give rise to thoughts, memories, behaviors and myriad other functions.

A map of SARS-CoV-2 escape mutations enables the development of therapeutic antibody cocktails

A recent tour-de-force study by the US researchers describes a comprehensive approach to completely map mutations to the SARS-CoV-2 receptor-binding domain (RBD) that escape antibody binding – enabling, in turn, rational design of antibody therapeutics and appraisal of the antigenic consequences of viral evolution. The results are currently available in a bioRxiv preprint paper.
