Not every cell react the same way to caspase activation. In our recent study (led by @tomcumming.bsky.social and initiated by @avillars.bsky.social ), we tried to better understand what explains this difference and outlined a role of past caspase exposure 👇 www.nature.com/articles/s41...

One of these days I'll nab a top 5 spot... congrats to the winners! www.nikonsmallworld.com/galleries/20...

Excited to announce that the Rikki Garner lab has opened its doors in beautiful Austin, TX! Our interdisciplinary lab @utaustin.bsky.social MBS investigates tissue fluidity as a universal physical regulator of multicellular patterning in health and disease. www.rikkigarnerlab.org 1/n

🔬🧪 We're hiring postdocs&engineers at Institut de la Vision in AMAZING Paris 🇫🇷!! Join a dynamic team working at the nexus of retina developmental biology, spatial omics & advanced imaging Ambitious science in a supportive & young inclusive team 🚀 DM me for more info & please share 🙏 #academicsky

In zebrafish, neural stem cells keep producing neurons throughout life. Pasteur scientists reveal how Notch3 signaling coordinates neighboring stem cells to maintain this balance, insights relevant to brain tumours. www.pasteur.fr/en/research-... @natcomms.nature.com #Neuroscience #StemCells

We would like to add one or two postdocs to our lab in the next couple of years. If you are close to finishing your PhD and interested in the science we do, feel free to reach out to discuss opportunities.

Happy #FluorescenceFriday! ✨🔬 A peek inside a developing quail embryo, where the brain and heart are already taking shape. A tiny embryo doing some seriously impressive developmental heavy lifting. 💪❤️ 📷 @vanderspuy.bsky.social

The kinetochore is essential for cell division across species, but its components and organization evolve dramatically. How can that be? Our first foray into this fascinating question is up now on biorxiv: 🧪 1/12 www.biorxiv.org/content/10.6...

Reminder! The 2026 African Turquoise Killifish Conference is coming to MDI Bio Lab Oct 1–3! Researchers studying aging, regeneration, development & disease are invited to join this hybrid meeting focused on collaboration and scientific discovery. #genesky #scicomm #devbio

Looking for a postdoc to join our project studying actin and membrane dynamics during cell migration. If interested, please reach out to me via email: rytis.prekeris@ucdenver.edu

We're excited to present a single-cell atlas of vertebrate cranial motor neuron development, the first story from my postdoctoral work in the Moens lab, up now on bioRxiv!

We are excited to share our collaboration with @pheereynolds.bsky.social, Robert Hindges & team on retinal plasticity, now out in Neuron! This work shows how visual experience during early development changes the anatomical and functional properties of amacrine cells and ultimately behavior!

Join us on a journey into the dynamics of cells during embryo development. We are offering a fully funded PhD position to investigate cell behavior using cutting-edge quantitative live imaging at the interface of Development, Immunity, and Tissue Biology. embryobioimaging.com

I am excited to present our newest report on a severe outbreak of transmissible cancer in clams in the Pacific Northwest, with a lot of unexpected twists. Led by Sydney Weinandt and Zach Child. www.pnas.org/doi/10.1073/pnas.2611852123 1/14

Annual killifish continue to surprise us: they make neutrophils before almost every other cell type, even before gastrulation. Neutrophils usually arise from the lateral plate mesoderm (forming in cyan), but in killifish they are already patrolling around the embryo in gold. tinyurl.com/killiphil

What if an embryo made immune cells before it finished building the tissue they usually come from? In our new preprint, we show that annual killifish embryos specify neutrophils before germ layers are fully resolved. www.biorxiv.org/content/10.6... Huge thanks to my PI, @ohnolog.bsky.social ! 🧵

First pre-print from the lab, a collaborative effort led by Jess Bourn @bournsupremacy.bsky.social, a fantastic PhD in my group. We resolve a key problem in development + evolution: how do we quantify heterochrony and link temporal variation to phenotype? www.biorxiv.org/content/10.6...

Is there a size limit for cells ? How can cells replicate inside the architecture of their environment? Why do cells self-destroy ? This 15-minute movie vimeo.com/1173229237 shows our 2026 edition of the Living Architectures project at the @museeorsay.bsky.social

Cell scaffold microtubules regulate tissue macrophages' migration & other roles as they participate in epithelial surveillance & wound repair 📹 @errricpeterman.bsky.social et al @uwbiology.bsky.social in @jcellsci.bsky.social ➡️ bpod.org.uk/archive/2026/6/18 with @antdlewis.bsky.social

Happy #fluorescencefriday (and start of vacation!) to all those who are celebrating Lifeact-labeled epidermal stem cells closing a wound after in vivo adult zebrafish skin injury

Dendritic atoh1a+ cells serve as Merkel cell precursors during skin development and regeneration Read this #LifelongDevSI #OA Research Article by Evan Craig, Jeremy Rasmussen @jraslab.bsky.social and colleagues at @uwbiology.bsky.social: journals.biologists.com/dev/article/...

🔎 New from the @jraslab.bsky.social at UW! They used #Langerhans cells within the adult #zebrafish epidermis as a model to investigate roles of microtubules in immune cell tissue surveillance, phagocytosis, and directed migration. 🦓🐟 See it in @jcellsci.bsky.social : https://bit.ly/49fmQhf

Congratulations to @errricpeterman.bsky.social for the second-ever journal cover from the lab!

A small primer on the #NobelPrize awarded to Mary E. Brunkow, Fred Ramsdell and Shimon Sakaguchi today. This prize was for combining two separate fields of immunology research - genetic research on IPEX and immunology research of regulatory T cells (#Tregs), with enormous impact on biology/medicine

cover image yeeeeeeeeehawwwww #flourescentfriday check out our work in the most recent issue of @jcellsci.bsky.social !

Latest paper from the lab! 👀 Check out this macrophage (labeled with a microtubule reporter in blue) avoid an epithelial obstacle (labeled with a nuclear reporter in pink) as it migrates to a wound (off screen to the left) ⬅️ Video credit: @errricpeterman.bsky.social

Thank you @jcellsci.bsky.social for this research highlight "Microtubules help macrophages navigate the epidermal maze" as a companion to our manuscript from @errricpeterman.bsky.social ! journals.biologists.com/jcs/article/...

Congrats to @errricpeterman.bsky.social on leading our latest paper now published in @jcellsci.bsky.social ! Eric found multiple roles for microtubules in tissue-resident macrophage homeostasis and function -- including in helping macrophages navigate around epithelial obstacles during wound repair👇

My awesome Drosophila colleague Akhila Rajan at Fred Hutch (Seattle) is recruiting both a staff scientist and a postdoc to study fat–brain communication, innate immunity, mitochondrial signaling, and brain senescence. Great team, great environment. Apply here: careers-fhcrc.icims.com/jobs/30062/j...
