Molecular insights may foster effective therapies for COVID-19 patients

Viral and bacterial pathogens wield pathogenic or virulent proteins that interact with high-value targets inside human cells, attacking what is known as the host interactome. The host interactome is the network map of all the protein-protein interactions inside cells.

Elegant, efficient way to find recombinant SARS-CoV-2 viruses from >85,000 genomes

The low divergence of near-identical genomes that are sequenced in short periods presents a statistical challenge that is not addressed by methods available currently. In a recent bioRxiv** paper, Ales Varabyou et al. from John Hopkins University present an efficient method designed to detect recombination and reassortment events between clades of viral genomes – a new algorithm called ‘Bolotie’.
