As 2025 comes to a close, my university (Dalhousie U in Halifax, Canada) is recruiting faculty, including outstanding early career researchers, and Canada Research Chairs. Applications are due January 19 2026 (was just notified today!). Please repost.

Getting ready for holiday reading. Provocative title, @mads100tist.bsky.social @chrmosimann.bsky.social 😉

As the semester ends, grades are entered, and grants written, I reflect on the challenges of the past year. World events weigh heavily on us, but we can still marvel at the discoveries over the past year. I wonder what will make the customary top lists of scientific discoveries for 2025.

🚨 PhD Position Available 🚨 I’m recruiting a PhD student to join my lab at the Multiscale Imaging Centre (MIC), Münster, Germany. www.bischofflab.com/jobs Fully funded ✅ #Cellbio #Morphogenesis #Microscopy #Drosophila #PhD (Details Below) Original Posting: stellen.uni-muenster.de/jobposting/d...

Starting shortly! Looking forward to hearing about Sabertoothed cats.

I'm thrilled to share the news that the original Tiktaalik fossils, including the Type Specimen itself, will be on display in Ottawa starting December 19! Check them out. nature.ca/en/visit-us/... 🧪

Sobering.

A rare sea slug who dares to make food from sunlight found in waters near a beach not too far from Halifax, Nova Scotia. Really interesting adaptation. If only we could do this trick…

Voyager 1 is almost one light-day from Earth. The intrepid #spacecraft will cross a major distance milestone in November 2026 - 16.1 billion miles. #Voyager1 #lightday Link for more information: www.popsci.com/science/voya...

Dalhousie offers generous Killam scholarships for both Canadian and international students. My lab is looking for graduate students, and is an exciting opportunity, especially for folks looking to do science in an interesting part of the world.

Stunning work from the Lichtman Lab & Google Connectomics: a true 3D EM reconstruction of a single cortical neuron, with every yellow dot marking a synapse. AI tools trace thousands of spines, revealing the micro-architecture of cortical computation. One cell, an entire universe (Nicolas Hubacz)

Our work out in @devbiol.bsky.social, PDGFra is needed for 🧠 perivascular fibroblast development... ⬇️ perivascular fibroblast = ⬇️ perivascular macrophage...cross-talk? 👀 Led by Hannah Jones @hejcell.bsky.social w/ Kelsey Abrams, Sophia Kim, excited for more projects w/ @fantauzzolab.bsky.social!

Our department @ucdavisvetmed.bsky.social @ucdavis.bsky.social is hiring! We welcome research that diversifies or complements existing strengths in gastrointestinal, neuroimmune, musculoskeletal, cardiorespiratory systems and/or developmental biology. @socdevbio.bsky.social @ascbiology.bsky.social

Dear #Neuroscience researchers, I am Guest Editing an issue in @devdynamics.bsky.social on NEURAL MIGRATION. Due date: March 31, 2026. Great opportunity to showcase your findings on neural migration. #DevBio Please reskeet 🙏 anatomypubs.onlinelibrary.wiley.com/journal/1097...

New IJDB issue! Our cover image features an immunostaining of neural crest cells and their derivatives in an Mllt1 E10.5 murine embryo from the paper by Zinck et al doi.org/10.1387/ijdb... Congratulations to the team of @aineurolab.bsky.social for their outstanding contribution!

Happy to report that our recent findings on the innervation of the masseter made the cover of the International Journal of Developmental Biology @isdb.bsky.social . Early post for #FluorescenceFridays #DevBio @brchfx.bsky.social 🧪 ijdb.ehu.eus/issue/69/

“I’d like to teach the world to sing, in perfect harmony…”

Finally had a bit of time to see @neilshubin.bsky.social Collège de France lectures on YouTube on our evolutionary journey on this rock. Wonderful. Thank you @denisduboule.bsky.social for making these accessible for those of us living far away from the City of Lights.

"Are we going to support talent here in Canada and the development of our students and our researchers who are here?'" Whitaker asked…simply injecting a wave of high-profile academics at the top without supporting the foundation beneath them is "going to leave us short-changed." @caut.bsky.social

The passing of A. Garcia Bellido es.wikipedia.org/wiki/Antonio... means another pioneer of #DevBiol leaving the room. An impactful personality who could create an intellectual storm w/ a sentence. Here from a discussion with L Wolpert pubmed.ncbi.nlm.nih.gov/9654040/ #Drosophila #CellsRUs #Genes

Does anyone know how to turn off copilot in word? An update has forced it presence onto the page margin (bottom right). And I could not find any way to turn it off in the preferences.

I'm thrilled to be able to share this new paper from post-doc Camilla Teng @xsciteng.bsky.social and our collaborators in the Leslie-Clarkson lab @emorygenetics.bsky.social on mechanisms of tissue fusion and cleft lip url: rupress.org/jcb/article/...

I'm curious as to why @bylinetimes.bsky.social are running tech corporation talking points, including pushing them out to hundreds of thousands of people. Here's my recent post breaking down why this line is so profoundly misleading: ketanjoshi.co/2025/08/23/b...

The CSMB is concerned that, despite new investments, Federal Budget 2025 weakens rather than strengthens Canada’s research ecosystem. Sustainable research funding is essential for innovation and competitiveness. Read more: csmb-scbm.ca/csmb-stateme... #CSMB #Budget2025 #ResearchCanada #Science

Grant submitted. Time for walk @dalhousie.bsky.social, leaves blanketing the ground. The cloudy calm before the hurricane fuelled weather tomorrow.

We are looking for graduate students to start in the summer or autumn 2026. Open to students with BSc or MSc degrees. Come explore the maritime region of Canada and do developmental and cellular neuroscience. Please see attached poster. Appreciate reskeets. #DevBio, #Neuroscience 🧪

Fantastic opportunity at The Hospital for Sick Children. Please repost. www.nature.com/naturecareer...

Dinosaur with hooves? Remarkable fossil find, including detailed skin impression, from Alberta. Hooves are eg of convergent evolution. But for what, fast, efficient, locomotion?

🎆 Join us for an unmissable finale to 2025! 🎆 We're thrilled to bring our #cilia & #centrosome community together 25/11/2025 15:00-17:45 GMT! Our 53rd @bscb-official.bsky.social @gensocuk.bsky.social @ukcilianetwork.bsky.social e-symposium schedule is live: www.eventbrite.co.uk/e/bscb-genso... /1

It’s Friday. And today I’m thinking of rivers in a time of dryness. And @robgmacfarlane.bsky.social’s new book “Is A River Alive”. As I read, I think about Peter Gabriel’s lament: “Living river, carry me on Living river, carry me on River, river, carry me on To the place where I come from”.

I'm very excited to announce that UNC Biology has 6 faculty positions open this year! The first is for an Asst Professor who studies organismal resilience using an integrative approach 1/n unc.peopleadmin.com/postings/307...

Happy Saturday everyone. I got a joke for you: Why do bees have sticky hair? Because they use honeycombs!

The @crick.ac.uk is recruiting Early Career Group Leaders - Lab set-up, research costs, salaries for up to 5 researchers - Support for up to 12 years - Access to our core facilities - Competitive salary - Fantastic colleagues - All areas of biology Deadline 27 Nov www.crick.ac.uk/careers-stud...

Interesting to know that John Maynard-Smith, like John Gurdon, went to Eton College, are both were made to feel that science was not for them. Fortunately for us, they decided to not listen to their masters at the college and contributed brilliantly to biology.

Well, this is interesting.

Philip nicely summarizes recent findings from Sebé-Pedrós and colleagues that the origin of multicellular life may come down to extrusions of DNA topology, juxtaposing far-flung genomic regions in the spatiotemporal regulation of gene expression.

Quite the start for John Maynard-Smiths classic little book: “Shaping Life: Genes, Embryos, and Evolution”. #DevBio

Tunneling nanotubes connecting neuronal dendrites in mammalian brains pass ions, allowing propagation of electrical signals in networked clusters of neurons. Also large enough to pass proteins like beta-amyloid, possible mechanism for spread of neurodegeneration.

Very sad news, John Gurdon has died. A developmental biologist's developmental biologist, Nobel prize winner His work is the foundation of much of today's dev & stem cell bio. An inspiration to many, including me. Always asking questions & wanting the answers www.magd.cam.ac.uk/news/profess...
