My friends in the Life of Retaria group decided to make a podcast! In the first episode, they interview @fabnot.bsky.social about his journey as a scientist. I loved the first episode, hope you do too! @juliemeilland.bsky.social @sandinmm.bsky.social et al.

I think that's a typo!

Evolution and origins of multicellularity across the tree of life The study of the origins and evolution of multicellularity in different lineages has recently captured the attention of many research groups and is fueling the generation of numerous innovative resea…

@amoebadiscovery.bsky.social made an iteresting interview with me about #heliozoa and #centrohelids - I think these organisms are really important, understudied and gorgeous 😍 Also lots other intresting reading and beatiful pictures! #protistsonsky link: tinyurl.com/adiscovery1

Cell cycle arrest in the cnidarian-dinoflagellate symbiosis.

Corals maintain stable populations of essential photosynthetic symbionts by controlling their cell cycle, not by eating them! Our new #PNAS paper monitored and modelled #aiptasia cell cycle, autophagy, and expulsion for over a year. #symbiosis #microbiology www.pnas.org/doi/10.1073/...

Oxford historian faces deportation from UK after doing research on India … in India Home Office told Manikarnika Dutta to quit Britain for spending too many days abroad for study

This. A thousand times this.

"If the UK genuinely seeks to position itself as a global leader in academia and innovation, it must foster an environment that is welcoming to top talent."

"[coiled-coil domain-containing] proteins are part of the stalk sheath, and their N-glycosylation may enhance adhesion between the cell body and stalk through lectin interactions [in E. hentscheli]"; epidermal growth factor-like proteins also key stalk components

Epistylis hentscheli - (A–C) Images of WGA staining (green), DAPI staining (blue), centrin (pink) and target antigen of the anti-CCDC antibody (red) by immunofluorescence using confocal microscopy, with a single section of the merged images (D).

Decoding the Nature of the Peritrich Stalk: A Distinctive Organelle in a Large Group of Ciliated Unicellular Eukaryotes Ciliates represent a diverse assemblage of ancient single-celled eukaryotes characterized by diverse morphological features. Among certain sessilid peritrich ciliates, an exceptional morphological st...

Really interesting look at the makeup of the peritrich stalk: onlinelibrary.wiley.com/doi/full/10....

We got to tackle three major questions in biology. So if you are interested in...
A) The nature of LECA
B) The relevance of patchy proteins for cellular models
C) The trafficking machinery present in diplonemids
have we got a paper for you!

Illustration depicting the ways in which fungi can exchange genetic material with each other. Starship mediated HGT is confirmed experimentally in this preprint.

We did it! We caught Starship #transposons moving between #fungal species in the lab, including between species separated by ~100my. We think Starships are a mediator of HGT in fungi, akin to conjugative elements in bacteria. Check out the preprint. www.biorxiv.org/content/10.1...
