Stochasticity, determinism, and contingency shape genome evolution of endosymbiotic bacteria - Nature Communications
Endosymbionts often have small genomes that maintain minimal functions required to serve their hosts. This study examines cases of new endosymbiont acquisition and finds genome degeneration involves both stochastic and deterministic processes that shโฆNature

Mesmerising microbes: bacteria as youโve never seen it before โ in pictures
โAs 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.โ

Never a Dull Enzyme
by Roberto โ The tricarboxylic acid enzyme citrate synthase from Synechococcus elongatus has the remarkable feature that it self-assembles into multimeric fractal shapes, specifically Sierpiลski 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.

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.
