RNA virus Journal Club is on! 🌳March 17th | Tuesday, 10 AM Berkeley time / 18 PM CET 🕰️ You've probably heard about the meta-virus resource? We will get to dive into metaVR database & huge viral diversity within thanks to @mattlabguy.bsky.social 🥳 All welcome! Details ⬇️ @rdrpsummit.bsky.social
what can be better than global RNA virome and Dolja? Nothing for me.. :) Join RNA virus club (by @rdrpsummit.bsky.social ) already tomorrow: Thu, Feb 12, 11:00 AM Pacific Time (US 🇺🇸, Canada🇨🇦) (or 7pm London time 🇬🇧) for an hour with one and only Prof. Valerian Dolja (Oregon State University)
🦠🧪🧬🚨 New paper and database alert: the new IMG/VR release is now MetaVR ! We have a new website - meta-virome.org - with quick search capabilities for the >24M viruses, >12M vOTUs, and >42M protein clusters (including >790k with predicted structures !). academic.oup.com/nar/advance-...
Meta-virus resource (MetaVR): expanding the frontiers of viral diversity with 24 million uncultivated virus genomes
Abstract. Viruses are ubiquitous in all environments and impact host metabolism, evolution, and ecology, although our knowledge of their biodiversity is st

detectEVE: Fast, Sensitive and Precise Detection of Endogenous Viral Elements in Genomic Data
Endogenous viral elements (EVEs) are fragments of viral genomic material embedded within the host genome. Retroviruses contribute to the majority of EVEs because of their genomic integration during t...

A newly discovered archaeal cell has a tiny genome and can’t metabolize biomolecules. It’s upending biologists’ definition of a living thing. “These types of organisms have been found before, but not as extreme as this,” said microbiologist Thijs Ettema.

The newly described microbe represents a world of parasitic, intercellular biodiversity only beginning to be revealed by genome sequencing.
