Some of the longest-lived organisms on Earth aren’t whales, trees or corals, but microbes buried deep in the earth. This eye-opening essay examines the slowest lives on Earth, asking what such lives mean for how we define life itself @karenlloyd.bsky.social

“A process which led from the amoeba to man appeared to the philosophers to be obviously a progress - though whether the amoeba would agree with this opinion is not known" - Bertrand Russell, 1976. Time-lapse video of Vampyrella lateritia eating Spirogyra algae from Science Source/Oliver Skibbe. 🦠

Can’t wait!! My bacterial cell bio friends, you’re gonna want to go to this GRC and GRS.

Absolutely stoked to have this published in @plosbiology.org We looked at the metabolism of #Klebsiella pneumoniae 🦠🧫. We not only demonstrated lineage-specific #metabolism, but that lineages can cross-feed and support each other. journals.plos.org/plosbiology/... #MicroSky #microbiology 🧬 🧪 💊

The diderm cell envelope is not a stack of layers but a unified scaffold of Inner Membrane–Peptidoglycan–Outer Membrane. We discuss how tethering the OM to the PG in E. coli preserves integrity — and extend the concept across diderm bacteria. Curr Opin Microbiol: doi.org/10.1016/j.mi... #microsky 🔬

I am recruiting graduate students for Fall 2026! The Microbial Ecosystems Lab @hot-mes-asu.bsky.social at ASU studies microbial interactions, spatial ecology, and imaging-driven microbiome science. If you love microbes, microfluidics, or single-cell analysis, let’s talk! www.microbialeco.systems

New release of the TrackMate single particle tracking plugin for ImageJ by @jytinevez.bsky.social looks amazing! forum.image.sc/t/trackmate-... Loads of new features, most excitingly to me deep learning segmentation algorithms including Omnipose (for cells), and Spotiflow (for spots) #bioimaging

Weird word of the day: "kleptosquamy." The testate amoeba Awerintzewia cyclostoma steals scales from other amoeboid organisms to build its own shell. This one has robbed Quadrulella, Netzelia, various euglyphids, and even an Acanthocystis. Kleptosquamy! #amoebae #ProtistsOnSky #biology #nature

Prashant Singh in the lab of Tina Iverson at Vanderbilt published this image of the bacterial 🦠flagellar motor, a detailed molecular model made possibly by CryoEM 🔬. The similarity to mechanical motors are strong enough we can use terms like stator, rotor, rod & gearing to describe it.

🚨 Imagine a bacterium that refuses to follow the textbook: It grows as tangled filaments, divides unevenly, reshapes its own membranes… and even builds grappling hooks. Meet Litorilinea aerophila — and here’s why it blew our minds.

Just published the first chapter of my thesis! 🥰 E. coli regulates the levels of a translation release factor (RF2) via a *purposeful* frameshift during translation. We found that most other bacteria do this too and it's likely an ancient mechanism! journals.asm.org/doi/10.1128/...

Latest from the lab! Analysis of everyone’s favorite regulatory mechanism in bacteria — the RF2 programmed frameshift! Likely present in the ancestor of bacteria, use of this mechanism is influenced by stop codon usage! Big congrats to @cassidyprints.bsky.social journals.asm.org/doi/10.1128/...
