Novel research reveals thriving microbial life in trees phys.org/news/2025-08-reveals-…
A diverse and distinct #microbiome inside living trees nature.com/articles/s41586-025…
"A single tree hosts about one trillion #bacteria in its woody tissue... #microbes are partitioned between heartwood and sapwood with each having its own unique microbiomes with minimal similarity to other tissues... They are actively producing gases and cycling nutrients... these communities may have coevolved with #trees over time"

#Microbes used poison gas in battle for iron in the Earth's early oceans phys.org/news/2024-10-microbes…
Inhibition of phototrophic iron oxidation by nitric oxide in ferruginous environments: Verena Nikeleit et al. nature.com/articles/s41561-024…
"A new study investigates how various #bacteria excrete insoluble iron as part of their metabolic processes. Some—the phototrophic iron oxidizers—gain energy by oxidizing Fe with the help of sunlight, and others by reacting Fe with nitrate as an oxidizing agent."
Some microbes used poison gas in battle for iron in the Earth's early oceans, geomicrobiologists find
Early in the Earth's development, the atmosphere contained no oxygen. Yet the iron dissolved in the oceans was oxidized in gigantic quantities and deposited as rock. It can be seen today, for example, as banded iron ore in South Africa.University of Tübingen (Phys.org)

"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."

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.”

Minimalist or maximalist? The life of a #microbe a mile underground
phys.org/news/2023-11-minimali… paper: ami-journals.onlinelibrary.wil…
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."

Endless microbes most beautiful and most wonderful
"To reflect the importance of microbes and to create a home for microbiology research using genetics, PLOS Genetics will be launching a new section on Microbial Genetics. "
As we (humans) get to grips with how to scale up #hydrogen as an energy source (and for energy storage) and as part replacement for #fossilfuels, this new research (once again) shows that #microbes have beaten us to it and evolved their own solutions for energy - in this case using hydrogen power.
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.
