From polymicrobial water kefir grains to PCD in biofilms, microorganisms are magnificently multicellular! Thanks to @embo.org @ibe-barcelona.bsky.social for having Lena Friebel and Thorsten Mascher @tudresden.bsky.social as well as @escolizzi.bsky.social at the #Multicellverse workshop

You can’t talk about microbial multicellularity without mentioning Streptomyces - check out our collaborator Daniel Rozen’s experimental evolution of these filamentous bacteria! Thanks @martaalvarez.bsky.social for snapping a pic! @embo.org #Multicellverse

Our head of #SPP2389 Thorsten Mascher also put the spotlight on the multicellular microbial communities of water kefir - thanks again @evolvedbiofilm.bsky.social ! @embo.org #Multicellverse

Lena brought her research on cannibalism in Bacillus biofilms to the @embo.org multicellularity workshop! Thanks @evolvedbiofilm.bsky.social for the picture! #Multicellverse

All cells – from mammalian cells to microbes – can follow different biological paths. Whether they grow and divide, specialise, age or die depends on the pathway they take. New findings by researchers at ETH Zurich could help influence a cell’s decisions to target diseases such as cancer.

A bit late 🙃 but happy to share our recent findings on #cdiAMP signaling in controlling #cyanobacteria #diurnal rhythm in @cp-iscience.bsky.social www.cell.com/iscience/ful... #cdiAMP is involved in almost all cellular processes, explaining it's essentiality in #cyano @hhu.de @mibinet.bsky.social

PhD position on Regulation and Evolution of Bacterial Multicellularity ( #Streptomyces ) within @spp2389.bsky.social supervised by Natalia Tschowri (Hannover 🇩🇪) and Danny Rozen (Leiden 🇳🇱) with research at both locations deadline: October 31, 2025 www.uni-hannover.de/en/jobs/id/802

Streptomyces and other filamentous actinomycetes are treasure troves of a vast collection of antibiotic compounds - an evolutionary feature linked to their unique multicellular lifestyle

Curious about kin recognition systems? Take notes from Proteus and Myxococcus! @ucberkeleyofficial.bsky.social

Congratulations to our Matthias for winning the @femsmicro.org international microorganism day microbe art contest for best photo and best overall! 🎉🦠 Biofilms truly are beautiful works of multicellular microbial architecture 🏛️ www.internationalmicroorganismday.org/microbeart
