It looks like there is considerable murmuration happening in @bluesky by flocks of #science! Time to migrate... I will switch to using a handle for our physical biology of #embryos lab @McMaster. Please follow: bsky.app/profile/pbodslab.bs…

Excited to speak at next week’s VGZT!
Next week, we’re back with two unique development talks: mouse gastruloids 🐭 with @KStapornwongkul and turtles 🐢 with Agáta & Barbora. Mark your calendar—you won’t want to miss this! 🗓️ Dec 5, 12:30 EST / 18:30 CET / 17:30 UTC 🕥

Happy that the backbone project of my postdoc research is published out @Dev_Cell !
🌟 New Paper Alert! 🚨 How does a developing embryo know where to place somite boundaries? 🦴🐟 Our latest study authors.elsevier.com/a/1kATe… in @Dev_Cell reveals a missing piece of the puzzle involving ERK oscillations and the segmentation clock (nature.com/articles/s41586-0…) (1/)

This project eventually bud off the published work which showed how to convince vertebrate embryos lacking a molecular clock to make somites: nature.com/articles/s41586-0… Unexpectedly, clock, a shortlived transcriptional repressor, lowers ERK activity by stabilizing ERK posphatases!

thanks all in @OzbudakLab and beyond who ended up collaborating with me and teaching me new things in this project as it came to its present form: authors.elsevier.com/c/1kATe…

Wonderful news Masha; to the many cool microscopy and discoveries!
🪰🔬🦠Happy starting my "Cell immigration" lab at fantastic @MSKCancerCenter!! #microscopy, #modelling #Drosophila #organoids. Looking for postdocs, students - come join us🫐 here in NYC mskcc.org/research/ski/labs/…

Looking forward to host you here @McMasterU as well on Thursday! @machealthsci @biogradmcmaster
Ontario friends I am visiting next week! On Wednesday I'll be speaking in Toronto at the MaRs building (1PM in 15th floor seminar room). On Thursday I'm speaking at McMaster (4-5 in MDCL). I'll talk about what happens when flies taste bacteria & swarm intelligence in stem cells!

The desynchronization of cell divisions in early mammalian embryos—once seen as a random process—instead plays a crucial role in ensuring robust development, shedding light on how embryos maintain precision despite biological noise, researchers report in Science. bit.ly/3Y523WH

Paul Dirac was so famously laconic that his colleagues joked about "a Dirac" being a unit of silence.

New preprint: We have developed an integrated pipeline to i) image gastruloids in toto with dual-view 2-photon🔬, ii) quantitatify cell and tissue-scale patterns of gene expression and morphometric features, iii) interact with the data in @napari_imaging. biorxiv.org/content/10.1101/…

I am on the job market this year for tenure-track positions in Canada and the US! My research program will investigate genetic and biological pathway bottlenecks in organ development that result in congenital anomalies, using animal models and microscopy imaging 1/2

1/ Thanks Rita! The @naturemethods comment follows from my “Confessions” talk last February and is motivated by my desire to recruit financial backers, AI collaborators, and highly motivated data scientists and biologists to join us for our “Cell Observatory” mission. youtube.com/watch?v=OhCVBx_Z…

A quick and thought-provoking read on the state of fluorescence microscopy and what it will take to tackle the most complex questions in biology from Eric Betzig. Highly recommended reading!
