New Mutations Identified in #BirdFlu #Virus
The virus, called #H5N1, has infected #cows in at least 36 #herds in nine states, raising fears that #milk could be infectious — concerns now largely put to rest — and highlighting the risk that many #viruses might jump across species on crowded #farms.
A #genetic analysis sheds light on when the #outbreak began, how the virus spread and where it may be going.

Happy to share the latest manuscript from our lab, in which we propose that eukaryotes evolved from a genomic chimera of Asgard archaea and giant viruses.

https://www.biorxiv.org/content/10.1101/2024.04.22.590592v1

This is a controversial topic, but we believe we have strong evidence to suggest a critical viral role in eukaryogenesis.

Viruses Finally Reveal Their Complex Social Life

Open questions in the social lives of viruses https://academic.oup.com/jeb/article/36/11/1551/7577264

"New research has uncovered a social world of #viruses full of cheating, cooperation and other intrigues, suggesting that viruses make sense only as members of a community."


Who are giant viruses infecting in the ocean?

In a collaborative paper with the Vardi lab, we were able to link many giant virus lineages to protist hosts using #SingleCell #RNASeq. One #protist host (leucocryptos) made up less than 1% of the community, but we could still identify a cryptic viral lineage infecting it, leading to population collapse.

Marine #microorganisms are crucial for #ocean health.

#Bacteria, #archaea, #fungi, #algae and #viruses make up most of the biomass in the seas and form the base of marine food webs.

They support nutrient cycling and drive crucial biogeochemical processes, including key steps in the carbon, nitrogen and silicon cycles.

Ocean modelling must evolve to take their biological complexity into account.

#GiantViruses encode many strange genes in their genomes - partial TCA cycles, actins and myosins, nutrient transporters, etc

What are they doing with all of these crazy genes?

Virophages are viruses that infect giant viruses, typically resulting in a lower burst size for the giant virus. In our latest preprint we report virophage-like sequences associated with insect poxviruses.

Their genomes of these elements are really interesting. This also opens up the possibility that hyperparasitic viruses are associated with a much broader range of DNA viruses than is commonly thought.
