Astonishing diversity and multifaceted biological connections of Type IV restriction-modification systems
Detecting co-selection through excess linkage disequilibrium in bacterial genomes
I wrote a short guide on how to build both alignment-free and reference-based prokaryote phylogenetic trees from SNP alignments without using snippy, check it out
SKA is a tool for comparing small and highly similar genomes using split k-mers. This guide will explain how to use SKA to build a phylogenetic tree for different Escherichia coli lineages in a few minutes. Although SKA is tailored more towards analysing variation within a lineage, tree-building ends up working fine for the whole species but requires more memory. Why SKA is good for building phylogenetic trees The basic approach to building a tree with SKA is to generate a SNP alignment using split k-mers and then feed that to a tree building algorithm of choice.
Sensing Blue Light: From Bacteria to Birds
by Mechas
That many birds migrate over long distances is a well-known fact. But reading the book "World on the Wing: The Global Odyssey of Migratory Birds" by Scott Weidensaul proved to be a true eye-opener. I also learned a fact that really stuck with me.

The Atlas of Cell Structure
by Roberto
Our knowledge of the structure of microbial cells just keeps getting better as the resolution of imaging techniques continues to increase. A key player in this rapidly evolving technological field is cryo-electron tomography (cryoET) which, aided by powerful computational tools, allows for the generation of three-dimensional images of whole microbial cells...

Talmudic Question #202
Why do bacteria – think Agrobacterium, Streptomyces, Borrelia among others – not care at all if they have linear and circular chromosomes and episomes (plasmids, prophages) side-by-side in one cell?

Ultrahigh-affinity transport proteins from ubiquitous marine bacteria reveal mechanisms and global patterns of nutrient uptake

Absolutely killer study, we need more work like this at 100x the scale. Need to think about the next generation of genome annotations.... and the data that will go into them
Transforming an existing phenotypic classification of viruses into one based on evolutionary relationships that can accommodate the vast number of viruses characterized in metagenomics and environmental studies is an ongoing challenge. This Consensus View explains how such a taxonomy can be expanded to encapsulate viral diversity and to recognize independent biological origins of different virus groups.
