Forecasting the Next Pandemic Led by scientists from Yale and the University of Oklahoma, the Viral Emergence Research Initiative (Verena) is one of the largest pandemic prevention research

Very special to wake up today to a profile of @viralemergence.org from Yale. We’re in month eight of turmoil right now, and it’s hard to focus on the science, but the truth is: we have a lot more work to do.

PearTree — Phylogenetic Tree Viewer

So I pleased to announce the conceptual spawn of FigTree: PearTree (acronym still to be finalised). If you want to dive right in it is hosted as a web app here: artic-network.github.io/peartree (click the “Example...” button for immediate candy and then click every button you can find).

You know that annoying NSF form "List every coauthor/co-PI from the last 4y" ?

At @cevianlabs.io we built a free tool that drafts the COI form from your PDF CV in minutes. Check it out 👇

ARTIC 2 measles resources are live!

As part of the Wellcome Trust funded ARTIC 2 project we have developed a collection of measles virus resources that are now openly available at artic.network/viruses/mev

This is finally out.

Very short take home. All the variation in spike that produced the immune escape characteristics of Omicron can occur in one single persistently infected individual over the period of a year.

This is why persistent infections matter

PacBio Sells Short Read Tech To Illumina PacBio has finally sold their short read sequencing assets to Illumina for ~$50M.

PacBio folds its short-read sequencing hand.
-Sad for us because Omniome's tech (the current Onso instrument) was promising for its Q40 reads that help those interested in calling rare variants accurately (like me).
-Sad for them too because $$$

Check out our new print that combines dense sequencing and phylodynamics to uncover a bunch of 😎 things about an understudied virus.

- Doesn't evolve for 10 months a year ✅
- Uses some mossies for maintenance, others for spread ✅

Microbial Evolution: Impacts on Human Health

Call for Papers

A defining characteristic of infectious diseases is that they evolve. The consequences of this evolution are among the most pressing medical issues facing humanity, including emerging pandemics, antibiotic resistance, and the success or failure of vaccines. Pathogen evolution profoundly influences virulence, transmission, and responses to a broad array of human interventions. While the evolutionary dynamics of pathogens have historically been challenging to study, large-scale genomic sequencing, novel computational tools, and experimental methods are rapidly changing the field. We encourage submissions on the broad topic of the evolution of infectious diseases.

This Special Issue aims to feature research that blends evolutionary approaches to understanding pathogen heterogeneity and ongoing genetic change in clinical samples and models of human infection. It also seeks to highlight opportunities to design treatment and prevention strategies that remain effective in the face of ongoing pathogen evolution.

Submission – open until January 31, 2027

Guest editors
Robert Woods, MD PhD, University of Michigan
Camilo Barbosa, PhD, University of Michigan
