We have a new preprint describing a method for #bacteriophage phylogenetics and comparative genomics.

Maybe useful for those interested in all the amazing #phages out there and their bizarre mosaic genomes

Very nice study from Henshaw et al shows that #marine heterotrophic bacteria can sense and move towards cyanobacteria when the latter are infected with #viruses.

Presumably the signatures of early infection are a sign that nutrients from a lysed cell will be available soon.

This is a nice study that has implications for understanding the role of viruses in the #ocean.

Ran my way back from work at 3AM to streak out Archaea cells from a very generous collaborator. First round of plates are already cooking in the incubator - once we have data we'll know something about conserved genomic architecture dating back 250 million years. Exciting.

A newly discovered bacterium, Uabimicrobium helgolandensis, eats other bacteria and is a kind of 'bacteria of prey,' that should not even exist based on previous concepts about microbial cells. It could be a kind of microbial missing link, researchers suggest.

Phage & Bacteria: A Space for Mutual Co-Existence
by Roberto — Phage-bacteria population dynamics can be remarkably complex. This is reflected in the natural history of both; new phage defense systems in bacteria and anti-defense systems in phage seem to be discovered daily. Behind these intricate strategies to help in the reproductive success of each lies the basic problem of any predator-prey relationship.

Mesmerising microbes: bacteria as you’ve never seen it before – in pictures

As a side hustle he manipulates and photographs the microbial world; his images are collected in a book, Beautiful Bacteria. Taking bacteria from substances such as wastewater, dental plaque or kimchi, Danino lets them multiply in a petri dish, adding dyes. The results are artworks differing from the digital enhancements often made in scientific photography to make images more informative.

Never a Dull Enzyme

by Roberto — The tricarboxylic acid enzyme citrate synthase from Synechococcus elongatus has the remarkable feature that it self-assembles into multimeric fractal shapes, specifically Sierpiński triangles. As Arthur Kornberg would have said: "Never a dull enzyme!"...

Who are giant viruses infecting in the ocean?

In a collaborative paper with the Vardi lab, we were able to link many giant virus lineages to protist hosts using #SingleCell #RNASeq. One #protist host (leucocryptos) made up less than 1% of the community, but we could still identify a cryptic viral lineage infecting it, leading to population collapse.

Looking for some suggestions - I'm working with Archaeal genomic regions whose optimally fitting model seems to be Tamura-Nei (https://doi.org/10.1093/oxfordjournals.molbev.a040023).

Would it be too much to suspect the Archaeal region is under similar types of evolutionary pressure?

French chemist and microbiologist Louis Pasteur was born #OTD in 1822

He is renowned for his discoveries of the principles of vaccination, microbial fermentation, and pasteurization, the last of which was named after him. His research in chemistry led to remarkable breakthroughs in the understanding of the causes & preventions of diseases, which laid down the foundations of hygiene, public health & much of modern medicine.
