This is from 7 years ago (merenlab.org/2019/02/24/f...). We are talking about the same things today. We will be talking about the same things 7 years from now. There is no one to blame for this apart from ourselves. I find it very depressing.

New publication out @natcomms.nature.com! We identify novel viruses that actively infect highly productive chemoautotrophs, and reveal key trophic interactions and virus-host dynamics that impact microbial carbon cycling in aphotic environments.

Ecosystem health shapes viral ecology in peatland soils - Nature Microbiology Metagenomics shows that viral diversity and community structure are shaped by geography and ecosystem health status, positioning viruses as unexpected players in peatland restoration.

Our paper "Ecosystem health shapes viral ecology in peatland soils" is out in Nature Microbiology!

We show that peatland health strongly structures viral communities, shaping virus–host networks, and carbon and nutrient cycling. Please share.

Comparison of short-read and long-read metagenome assemblies in a natural soil community highlights systematic bias in recovery of high-diversity populations Abstract. Comparisons of long-read and short-read (meta)genome assemblies typically show that short-read sequence assemblies are less error-prone, but stru

🧬🦠🚨 Another new paper alert, this time led by @maureenbug.bsky.social ! In collaboration with the Emerson lab and
@titus.idyll.org lab (@taylorreiter.bsky.social), both at UC Davis. Asking the question: what are we missing in short-read metagenome assembly, and why ?

My first PhD paper is out in @isme-microbes.bsky.social
We found that giant viruses are associated with carbon export to the deep ocean, supporting the viral shuttle hypothesis.

Lab’s first publication as #newPI @isme-microbes.bsky.social 😃

We observed evidence supporting the viral shuttle hypothesis in giant viruses. We also observed convergent evolution amongst giant viruses and bacteriophages to light-energy and nutrient limitation.

New from the Carter Lab!

Led by @bhuwanabbot.bsky.social, we sequenced almost twice as many complete genomes as were available for the endofungal Mycetohabitans genus.

Unsurprisingly, they are a little weird, giving us insight into endosymbiotic genome changes 🧬 🦠
