It’s out! Our paper “Marine Sediments Illuminate Chlamydiae Diversity and Evolution” was published in @CurrentBiology today! Below a thread with major highlights 1/11 cell.com/current-biolog…

We present PhyloMagnet, a workflow to screen meta-omics datasets for taxa and genes of interest. Developped by @maxemilschon in the @Ettema_lab academic.oup.com/bioinformatics…

This is a pretty cool discovery! biorxiv.org/content/10.110…

I'm beyond excited to share our first #plastic-#microbe article on bacterial candidates for colonization and degradation of #marine plastic debris in Environmental Science & Technology pubs.acs.org/doi/full/10.10… and my excellent student Line Roager's very first article 😊👑🦠

Lateral transfers repeatedly remodeled the oxygen detoxification pathway in Diplomonads, likely helping anaerobes like the parasitic Giardia intestinalis adapt to low-oxygen environments like the host digestive tract: buff.ly/2mutnPP @alejimgon @_feifeixu @janandericm

Ever wonder about the accuracy of gene predictions? We did. Turns out that gene callers are 5% or more inaccurate. They are particularly bad at choosing the correct start codon. Our collaboration with the Gonzalez lab at UCSD, now out in Bioinformatics: academic.oup.com/bioinformatics…


This is amazing

OK y'all, it is now my pleasure to show off some of the truly, genuinely heinous plots students in my Reproducible Data Analysis class made. Content warning: these plots are f***ing awful.

CB: Both raw read & consensus accuracy continue to improve. We’re seeing some great results from the Community, eg. Soren Karst’s method for long amplicons with UMIs had an error rate of just 0.03% across the whole rRNA operon of 4.4 kb bit.ly/30V2Iv4 #GenomeScience2019

The first plastid symbiosis likely took place in freshwater or terrestrial environments. Did it also occur in warm habitats?

When I die I want the academic publishing industry to lower me into the grave so it can let me down one last time. #academia

Great news everyone, the genome profiling manuscript is on #bioRxiv! We present in there GenomeScope and #smudgeplot. These tools have fundamentally changed my views on genomics, so I feel I should elaborate a bit 🤔

Proud of our new postdoc @PrecambrianGoat who published one of his PhD chapters in @NatureMicrobiol today “An archaeal origin of the Wood–Ljungdahl H4MPT branch and the emergence of bacterial methylotrophy“ nature.com/articles/s4156…
