Are you a long-time fan of Archaea, an extremophile-phile, or are you simply curious? Either way, we have good news. We’re delighted to announce the 2026 EMBO Workshop on Archaea, 6–10 July. Sign up: meetings.embo.org/event/26-arc... We look forward to seeing you in Cambridge, UK. Please repost!

Molecular Biology of Archaea: Life Through the Prism of Archaea

In 1977, Woese and colleagues revealed Archaea as a distinct domain of life. Building on this insight, the discovery of Asgard archaea has strengthened the view that many hallmarks of eukaryotic cell…

🥳 Our new paper on C2CD3 is out in @plosbiology.org With the labs of @cellarchlab.com , @chgenoud.bsky.social , and @stearnslab.bsky.social , we revealed the mammalian centriole Distal Ring architecture by combining #UExM and in situ #CryoET. Big congrats to @ebertiaux.bsky.social and all involved.

How does C2CD3 contribute to distal appendage formation in centrioles? @centriolelab.bsky.social show that C2CD3 acts as a central architectural organizer of the distal #centriole, bridging the luminal distal ring complex & peripheral appendage sites @plosbiology.org 🧪 plos.io/496XZuH

C2CD3 localizes to a ring structure observed in the lumen of the distal centriole by in situ cryo-electron tomography. Top: Confocal image of an expanded mouse photoreceptor cell immunolabeled for tubulin (magenta) and C2CD3 (green). DC, daughter centriole; BB, basal body; TZ, transition zone; CC, connecting cilium. Scale bar: 500 nm. Middle: In situ cryo-tomogram slices taken along the longitudinal axis of the centriole and connecting cilium. White arrowheads indicate microtubule triplets, black arrowheads indicate microtubule doublets, orange arrowheads mark the luminal ring structure, and yellow highlights the membrane. Scale bar: 50 nm. Bottom: Model of the architecture of the distal region of the human centriole.

The first article that I edited for @jcb.org is out! It's about presynaptic actin, it's in Drosophila, and it's from @biljanaermanoska.bsky.social, Jonathan Baets and @rodallab.bsky.social. Congrats for this neat work!

Nonmuscle myosin II regulates presynaptic actin and neuronal mechanobiology in Drosophila

Neurons and muscles must maintain structural contact despite mechanical strain. Ermanoska et al. identify a presynaptic actomyosin core at Drosophila neuro

OMG, this is such a cool paper from Patrick Caswell's lab. They express Rab25-mCherry-GFP-nanobody in cells, microinject GFP-magnetic particles, then use a magnet to pull Rab25 to the plasma membrane to show that it can trigger actin protrusions! I want this system. www.science.org/doi/10.1126/...

Live-cell magnetic manipulation of recycling endosomes reveals their direct effect on actin protrusions to promote invasive migration

Repositioning of Rab25 vesicles containing formin and integrin cargos to the cell periphery promotes protrusion formation.
