The Last Universal Common Ancestor of Ribosome-Encoding Organisms: Portrait of LUCA - Journal of Molecular Evolution
The existence of LUCA in the distant past is the logical consequence of the binary mechanism of cell division.SpringerLink
Genomic analyses of Symbiomonas scintillans show no evidence for endosymbiotic bacteria but does reveal the presence of giant viruses
Author summary Endosymbiotic bacteria are found in a wide variety of hosts across the tree of eukaryotes and have been proposed to be evolutionarily and ecologically significant, but in most cases, we know little to nothing about them.journals.plos.org

Follow the leader: A new study of #flagella in #algae reveals how they coordinate their movements to ensure cells steer efficiently https://elifesciences.org/digests/86102/follow-the-leader #protists #microbes
The younger flagellum sets the beat for #Chlamydomonas reinhardtii https://elifesciences.org/articles/86102
"To steer, C. reinhardtii adjusts the strength of the strokes made by each flagellum. Despite this asymmetry, the flagella must continue to beat in synchrony to move efficiently."
The younger flagellum sets the beat for Chlamydomonas reinhardtii
External hydrodynamic forcing on each flagellum of Chlamydomonas reinhardtii reveals a leader-follower relation between the two flagella in the synchronous beating.Da Wei (eLife Sciences Publications, Ltd)
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.”

#Mutualism on the edge: Understanding the #Paramecium–#Chlorella symbiosis https://journals.plos.org/plosbiology/article?id=10.1371%2Fjournal.pbio.3002563
"Exploring the mechanisms that underpin #symbiosis requires an understanding of how these complex interactions are maintained in diverse model systems. The ciliate #protist, Paramecium bursaria, offers a valuable insight into how emergent endosymbiotic interactions have evolved."

Minimalist or maximalist? The life of a #microbe a mile underground
https://phys.org/news/2023-11-minimalist-maximalist-life-microbe-mile.html paper: https://ami-journals.onlinelibrary.wiley.com/doi/10.1111/1462-2920.16543
Magdalena Osburn: "The deep subsurface #biosphere is enormous; it's just a vast amount of space... Many of the #microbes we found were either minimalist: ultra-streamlined with one job that it does very well alongside a close consortium of collaborators, or it can do a little bit of everything. These maximalists are ready for every resource that comes along."

If you added up all the microbes living deep below Earth's surface, the amount of biomass would outweigh all life within our oceans.Amanda Morris (Phys.org)

This new research in Nature Microbiology explores how hydrogen in seawater supports growth of multiple and diverse #bacterial species.
Fof those (like me) in #Melbourne , you may be interested that the research also includes study of this process within #PortPhillipBay sediments.

The Early Microbial Colonizers of a Short-Lived Volcanic Island in the Kingdom of #Tonga https://journals.asm.org/doi/10.1128/mbio.03313-22
"We didn't see what we were expecting. We thought we'd see organisms you find when a glacier retreats, or #cyanobacteria, more typical early colonizer species—but instead we found a unique group of #bacteria that metabolize sulfur and atmospheric gases."
Rare opportunity to study short-lived volcanic island reveals sulfur-metabolizing microbes
