Our photoswitchable HaloTag is out in Angewandte Chemie @angewandtechemie.bsky.social ! We now also show that this system can be used to control emitter density in SMLM. Congrats to Franzi, Bego, and our amazing collaborators. Check it out: onlinelibrary.wiley.com/doi/full/10....

Great thread about one of my very favorite cellular structures! Also home to one of our labs favorite proteins, Canoe/Afadin

A very curious paper from the De Robertis lab shows how Cerberus - a growth factor that inhibits Wnt signalling, and IGF - a growth factor that activates MAPK signalling, can synergistically induce a new head (aka ectopic archencephalic differentiation) in Xenopus embryos. doi.org/10.1016/j.cd...

MEIOC facilitates meiotic entry in the mammalian female germ line This Research Highlight showcases work by Esther G. Ushuhuda, Maria M. Mikedis (@mariamikedis.bsky.social) and colleagues: journals.biologists.com/dev/article/...

With support from the NIH, the Center for Economic Justice and Action is leading the FRESH Study to better understand how nutrition/basic needs shape the long-term health of young adults. Researchers hope findings will support investment in basic needs for college students: https://bit.ly/4shF5tv

Organoid technology is one of the most significant advancements deriving from developmental biology. Yet, many aspects of the biology of organoid itself remain elusive, one of which is the role of mesenchymal stem cells. This review: doi.org/10.1016/j.cd... by Wang et al discusses this in detail.

Axolotl can regrow lost limbs, matching their body size. How? Our new theory-experiment paper in @pnas.org proposes how oppositely oriented morphogen gradients scaling with animal size promote proportional growth. Great collaboration with @tatianasg.bsky.social @cmcb-tud.bsky.social

ECM as a cell-cycle brake. Led by Liyuan Sui (Dahmann lab), we show that the ECM gates Yorkie nuclear entry to halt proliferation at final size via G2 arrest in the Drosophila wing disc. Programmed ECM degradation later enables re-entry + proper adult wing size. Link 👇 #Mechanobiology #ECM

Excited to share Alison's @alisonkickuth.bsky.social paper from the lab out in @nature.com this week! We uncovered how a mechanical ratchet mechanism drives cytokinesis in early #zebrafish embryos. Read more in this thread 🧵 and at www.nature.com/articles/s41... 🤩 @poldresden.bsky.social @mpi-cbg.de

Our study illustrates how a single TE family can sculpt the regulatory architecture underlying a complex developmental cascade. It adds to a growing number of studies supporting Barbara McCintock’s prescient vision of TEs as “controlling elements” 💕 Hope you enjoy our preprint!

Another fascinating - and totally serendipitous - example of how human biological sex isn't always binary, despite executive orders that it is. In this case an XX/XY mosaic individual was a fertile female. Other XX/XY mosaics can be phenotypically male.

This went under the radar but answers a fundamental question in Epigenetics... From many hundreds of olfactory receptor genes, each neuron selects expression of only single one (near-randomly). How? Outstanding work from Mathieu Boulard and colleagues www.biorxiv.org/content/10.6...

When RNA Degradation 🤝 meets 🤝 Protein Degradation! tinyurl.com/E3TDMD In a collaboration of @bartellab.bsky.social and Schulman lab, we show that, in target-directed microRNA degradation (TDMD), 2-RNA-factors recruit an E3 ligase and induce the degradation of not only a protein but also RNA (1/5).
