This study identifies 908 new isomorphic eukaryotic signature proteins in Asgard archaea, suggesting their ancestor was more complex than previously thought.

The paper identifies tubulins in Asgard archaea and shows they form mini-microtubules with eukaryotic-like properties, suggesting an archaeal origin for microtubules.

This study investigates DnaA titration on the E. coli chromosome and shows it controls free DnaA levels in a growth rate-dependent manner, preventing re-initiation during slow growth.

WitChi detects and prunes compositional bias in phylogenomic alignments using chi-squared testing, improving phylogenetic accuracy in large datasets.

This study shows that complex nutrient environments drive genetic diversification in Bacteroides thetaiotaomicron through increased SNPs and DNA inversions, leading to adaptive traits like faster glucose depletion and amylopectin degradation.

This study shows that archaea can synthesize fatty acids using a newly identified pathway and enzyme complex, providing insights into their evolutionary lipid composition.

The paper identifies an Asgard archaeal Argonaute, HrAgo1, that performs RNA-guided RNA silencing, bridging the gap between prokaryotic and eukaryotic Argonaute mechanisms.

This study analyzes five new Korarchaeota metagenome-assembled genomes to reveal their phylogenomic position and genomic adaptations to habitat switching.

The paper analyzes bacterial endosymbionts in spiders, reconstructing their genomes and showing their evolutionary relationships and interactions with the host.

The paper analyzes the ecology, evolution, and genomic diversity of Rhabdochlamydiaceae, a chlamydial family infecting arthropods, revealing genome reduction and transposable element dynamics.
