Diversity, ecology, cell biology and evolution of the Asgard archaea - Nature Reviews Microbiology The Asgard archaea have become a cornerstone of archaeal research, particularly for studies aiming to unravel the origin and early evolution of eukaryotes. This Review outlines the current state of th...

Just over ten years after the discovery of the first Asgard archaeal genomes, we revisit the rapid expansion of this remarkable archaeal lineage. From diverse genomes and metabolisms to eukaryotic signature proteins and the first cultured representatives.

Gut bacteria rewire fat tissue to burn more energy Study reveals how the gut microbiome and diet work together to transform white fat cells into energy-burning beige fat in mice.

New research from @thexavierlab.bsky.social finds that the gut microbiome fine-tunes fat tissue in mice in response to diet, converting it from energy-storing fat to more energy-burning fat when dietary protein is low.

Exapted CRISPR–Cas12f homologues drive RNA-guided transcription - Nature Specialized σ factors interact with nuclease-dead, CRISPR–Cas12f proteins to form potent, RNA-guided gene activation systems that function independently of fixed promoter motifs.

Just amazing what evolution can come up with. Naturally occurring nuclease deficient Cas12 family members use gRNAs to bind DNA and recruit sigmaE family members that drive txn initiation proximally. 2 papers! 1- describes 2- structure!

Flexible paths to multicellularity Close relatives of animals can become multicellular if distinct individuals join together or if dividing cells remain attached. A species has been found to use both mechanisms.

This species can become multicellular using two mechanisms previously thought to be mutually exclusive

Structural insights into metallocluster trafficking in the nitrogenase assembly scaffold NifEN - Nature Catalysis Structural insights into the assembly of the complex nitrogenase cofactor are scarce. Now, cryo-EM and AlphaFold analyses of NifEN, which converts the precursor (L-cluster) to a mature cofactor (M-clu...

Fantastic collaboration w/ @dbikard.bsky.social @audeber.bsky.social @rayanchikhi.bsky.social labs led by @jmouradesousa.bsky.social : We assessed the rates of variation of anti-phage systems in P4-like satellites and P2 helper phages. Quick conclusion: Huge variation! We focus on 4 key questions/5

Protein–protein interactions (PPIs) are key to discovering and interpreting new biological functions.

We’re excited to introduce 𝑭𝒍𝒂𝒔𝒉𝑷𝑷𝑰: a new application of gLM2 that uses genomic language modeling to predict proteome-wide PPIs in microbial genomes in minutes.

A symbiotic origin of the ribosome? Abstract. The origin of life is one of the great mysteries of science. Of the multiple unsolved problems, the origin of the translation system (the means b

"we propose that the protoribosome was a parasite (...). If this view is correct, then like the spliceosome in the stem eukaryote, a repurposed host-parasite interaction led to a dramatic change in cell biology at the base of the tree of life, in this case leading to the exit from an RNA world"

How a tiny bacterium turns itself into a “tunneling machine” Some symbiotic bacteria can invade micron-scale host passages by wrapping their flagella around themselves and moving like a tunneling machine. Our study reveals how this clever motion enables them to overcome extreme confinement and successfully colonize their hosts.

Researchers in the US might be having feelings about writing grants atm-I know I am!

We still need to write them. In this Evolution Exchange, I again chat with Sam Scheiner, who summarizes how to write a competitive proposal.

His advice is gold, and helpful regardless of funder. Pls RT!

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).

Thank you so much for this perspective, Elise...it's exciting to see lipids getting a little time in the spotlight!! 🤩 #lipidtime @elisecutts.bsky.social

I’ve spent a lot of time over the past two years thinking about genome evolution and how recent research revealing complex gene-gene interactions has complicated traditional ‘gene-centric’ genomic approaches to evolution. So here is a review that consolidates these thoughts!

EBAMP: An efficient de novo broad-spectrum antimicrobial peptide discovery framework Zhao et al. propose EBAMP, a generative-discriminative framework for de novo design of broad-spectrum antimicrobial peptides (AMPs) targeting both bacteria and fungi. EBAMP achieves a high positive rate (37.5%), exhibiting strong antimicrobial activity against multidrug-resistant pathogens with low toxicity, offering a promising strategy against antibiotic resistance.
