EMBL meeting on Mechanobiology: @green-te.bsky.social en force, filling the two front rows and prominently featured with >10 posters or talks 🌱✊

Spend less time processing cell images with the Allen Cell Structure Segmenter. This #OpenScience python-based toolkit helps #cellscience researchers navigate complex images by automatically capturing the boundaries of structures. Access at: https://lnkd.in/gpWA7xWH

Our latest work on shape-programmable tissues is out in @science.org. By positioning topological defects in cellular nematics, we encode frustrated 2D force fields that relax into predictable 3D shapes. Collaboration with Marino Arroyo’s lab, led by @pauguillamat.bsky.social at @ibecbarcelona.eu.

🌱🔬We’re exciting to be hosting a new webinar series on quantitative plant imaging with @ajcellbio.bsky.social & @joemckenna.bsky.social. The first webinar will be on 30 April at 15:00 BST. For more info and to sign up to our mailing list or volunteer to give a talk ⤵️

New preprint 🌱 Segment plants in time-series images using foundation model SAM2 - without training a model 🪩. Magician Alex Abbey! 💡SAP works across species, scales, and even z-stacks. From single cells to whole plants→ quantitative growth & dynamics . tinyurl.com/3raedtvm @biosofttau.bsky.social

*Sharing code for research publications* Here's the process that I've ended up with, through various collaborators like Robert Forkel, @simongreenhill.bsky.social , Stephen Francis Mann and others. Not perfect perhaps, but works pretty ok. A student asked, so I made this illustration.

Very happy to announce that I will be joining the Faculty of Biology & @cibss.bsky.social at @uni-freiburg.de as an Emmy-Noether funded group leader. We will tackle the molecular and genetic basis of developmental timing and size control using diverse Oryzias species. We are hiring at all levels !

Our study on shape diversity in cnidarians is now published. The final version includes extensive new data that substantially extend the original bioRxiv preprint. Congrats to everyone who contributed to this work! www.cell.com/cell/fulltex... @embl.org

Deciphering mechanical determinants of morphological evolution

A comparative analysis of cnidarian larval morphogenesis combined with active surface theory identifies a set of mesoscale mechanical modules that predict species-specific shapes. Manipulating these m...

Who needs PowerPoint when you have Quarto and @emilhvitfeldt.bsky.social's extensions?! I wanted to make an image-heavy presentation. Usually, I'd reach for Keynote. But Emil shared quarto-revealjs-editable, which let me stay in Quarto land 🥰 Thanks, Emil! Find it here: github.com/EmilHvitfeld...

We recently published a first story on combining spatial and single cell transcriptomics in barley (see here: www.nature.com/articles/s41...) Lets go for the next level now, i.e. understanding gene networks and barley meristem development in 4D!

Spatially resolved gene expression during barley development was done by integrating an scRNA-seq dataset from cells with unknown position with spatial transcriptomics. This dataset is publicly availa...

dplyr 1.2.0 is out now and we are SO excited! - `filter_out()` for dropping rows - `recode_values()`, `replace_values()`, and `replace_when()` that join `case_when()` as a complete family of recoding/replacing tools These are huge quality of life wins for #rstats! tidyverse.org/blog/2026/02...

dplyr 1.2.0

dplyr 1.2.0 fills in some important gaps in dplyr's API: we've added a new complement to `filter()` focused on dropping rows, and we've expanded the `case_when()` family with three new recoding and re...

New preprint! SOSEKI polarity proteins are mechanoresponsive integrators linking growth and tissue mechanics during lateral root formation. Their polarity marks growth boundaries and reorganises in response to mechanical alterations —reshaping how we think about axis formation. tinyurl.com/28p7af2w

📢 It came to my attention that due to more restrictive recent regulations, our colleagues in Japan have immense difficulties shipping (receiving?) seeds by mail. Apparently, having someone carry them is the most reliable option. Anyone travelling soon from 🇯🇵 to 🇪🇺?

Our work on mapping the dynamics of phospholipids during lateral root formation is now published in @jxbotany.bsky.social We show that PI(4,5)P₂ plays a key role: targeted reduction in pericycle promotes LR development. → academic.oup.com/jxb/advance-...
