1/ Excited to share our new study with @brumbaugh-lab.bsky.social, out in @natbiotech.nature.com! P-bodies selectively sequester RNAs encoding cell fate regulators, often from the preceding developmental stage. Releasing these RNAs can drive changes in cell identity. 🧵 www.nature.com/articles/s41...

Really excited to present the results of a fantastic collaboration with Jesse Veenvliet @jesseveenvliet.bsky.social @mpi-cbg.de @poldresden.bsky.social 🤩 We find a unique mechanism for body axis elongation in mammals, different from other vertebrate species ➡️ www.biorxiv.org/content/10.1...

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....

Many proteins bind RNA, yet we still don’t know what RNAs most bind because methods map one RBP at a time. In @cp-cell.bsky.social, with the Jovanovic lab, we describe SPIDR – a method for mapping the RNA binding sites of dozens of RBPs in a single experiment. www.sciencedirect.com/science/arti...

What allows lamins A and C to confer much stronger mechanical stability to the nuclei than lamin B? We show that even though all lamins can protect the nucleus from small cell intrinsic forces, only lamin A/C protect the nucleus from large deformations: www.biorxiv.org/content/10.1... 1/n

1/ Super excited to share my first preprint from @andersshansen.bsky.social Lab! We used MINFLUX to track chromatin (H2B-Halo and Fbn2 locus) at an unprecedented 200 μs, then combined it with SPT to span μs-minutes (H2B) or SPT & Super-Res Live-Cell Imaging (SRLCI) to span μs-hours (Fbn2)

New paper out! Would you like to fluorescently label the plasma membrane in live, fixed or permeabilized cells? I tested different lipid structures and labelling approaches to decide what makes a good membrane labelling probe for such imaging experiments! www.biorxiv.org/content/10.1...
