TLDR: we recommend checking the genomic coverage of metagenomic taxonomic classifications from a tool like Kraken to remove false positives w/out large drops in recall. 1/
From classification to confirmation: verifying taxonomic classifications by mapping metagenomic reads to reference genomes
Background: Obtaining high precision while maintaining high recall is an ongoing problem for metagenomic taxonomic classification in microbial ecology research. Parameter adjustments can achieve this ...

Metabolic redundancy is required for microbial polyethylene assimilation. Cellular and metagenomic analyses show that redundancy of the fatty acid metabolism is essential to process the enormous pool of oxidised aliphatic metabolites generated by weathered PE #plastic www.biorxiv.org/content/10.6...
Metabolic redundancy is required for microbial polyethylene assimilation
Polyethylene (PE) is amongst the most recalcitrant synthetic polymers, and only a limited number of microbes have been shown to utilise it as their sole carbon and energy source. Here, we investigated...

We have created a bacterium that eats plastic! We named it PETBuster! Great work by PhD student Dekel Freund @dekel-freund.bsky.social.

A synthetic bacterium that degrades and assimilates poly(ethylene terephthalate)
Polyethylene terephthalate (PET) is the fourth most commonly used plastic worldwide. Like all plastics, post-consumer PET is poorly managed and accumulates in the environment, posing significant ecolo...

Not that you care, but I still wanted to let you know that if I see a paper full of bogus citations with your name on it, I'm not talking to you anymore.

I was so triggered by a paper I was reading this morning, I am drinking my second coffee.

Our latest paper, in which @brinda.eu (along with @zaminiqbal.bsky.social and others) introduces phylogenetic compression for storage and search of enormous microbial genome libraries, was published today in @naturemethods.bsky.social:

My editorial simultaneously published in all of @asm.org's journals addresses the ongoing effort by the administration to halt efforts to diversify science. It should be obvious from ASM Journals' efforts over the years, but we aren't fans journals.asm.org/doi/10.1128/...
A call for healing and unity | mBio
Executive orders signed since 20 January 2025 aim to end programs intended to diversify the scientific workforce via equitable and inclusive practices and processes; cut federal funding for research and innovation; and stifle scientific communications. They represent a stunning reversal of policies that have been the bedrock of the U.S. scientific research enterprise and its leadership in the world, and therefore not surprisingly they have been met with a number of legal challenges. Some of the executive orders have been blocked by temporary restraining orders, and others are pending judicial review.

I guess I’ll start off on here with my last tweet?

I’m pleased to share my new preprint with @betascience.bsky.social, where we introduce a new database for PICRUSt2 functional predictions.

PICRUSt2-MPGA: an update to the reference database used for functional prediction within PICRUSt2
Summary PICRUSt2 is a bioinformatic tool that predicts microbial functions in amplicon sequencing data using a database of annotated reference genomes. We have constructed an updated database for PICR...
