What would happen if cells would express more molecular motors ?
They would break all microtubules 😱
As shown by recent great work from @kjverhey1.bsky.social

that time of the year... writing letters for 8 UG's applying to grad school, each of them to ~15 programs. And while I passionately support every one of them, thats A LOT of letters, a lot of web sites to keep track of, a lot of my time. Why dont Grad programs use interfolio? One and done???

ATP-dependent remodeling of chromatin condensates reveals distinct mesoscale outcomes Adenosine triphosphate (ATP)–dependent chromatin remodeling enzymes mobilize nucleosomes, but how such mobilization affects chromatin condensation is unclear. We investigate effects of two major remod...

Today I am so pleased to present our work on how chromatin remodelers affect mesoscale chromatin organization.

Despite the current US Government shutdown, the National Cryo-EM Facility housed at Frederick National Laboratory remains open. FNL is operated by federal contractors that are forward funded and we have not run out of money yet. This status may change depending on the length of the shutdown.

Come join us in Oxford! Two positions open right now in @oxfordbiochemistry.bsky.social
It’s a great place to work. Really supportive colleagues, great students, colleges provide a unique social environment - in summary, it’s a lot of fun.

RNA polymerase II is a polar roadblock to a progressing DNA fork Nature Communications - Transcription–replication conflicts can threaten genome stability. Here, the authors show that RNA polymerase II (Pol II) is a stronger roadblock to a DNA fork in the...

Great work from Michelle Wang’s group at Cornell exploring how RNAP II and associated R-loops act as intrinsic roadblocks during mechanical DNA unzipping. These findings have mechanistic implications for transcription–replication conflict.

Tenure-track Position in Biophysics at Carnegie Mellon University, Department of Physics Location: Pittsburgh, PA Open Date: Sep 19, 2025 Description The Department of Physics at Carnegie Mellon University invites applications for a tenure-track faculty position in biophysics. The appointment is intended to be at the Assistant Professor level, but exceptional candidates at a higher level may also be considered. We seek outstanding candidates with a strong record in cellular and subcellular biophysics. Topics of particular interest include, but are not limited to, uncovering how key characteristics of living systems arise from the interplay between supramolecular cellular structures, how the emergent cellular circuitry defines goals and enables robust decision making, and how metabolic resources are allocated. This encompasses understanding of how information is learned, stored, transduced, and processed across subcellular structures. Applicants with theoretical, data science, or experimental backgrounds within biological physics are encouraged to apply. The ideal candidate will strengthen and extend research programs of current biophysics faculty in the Department of Physics and collaborate with broader life science activities across many departments at CMU and the wider Pittsburgh area. More details on Interfolio: https://apply.interfolio.com/174360

I am super excited to announce that we have a tenure-track faculty position in biophysics open in the Department of Physics at Carnegie Mellon! 🧪

What if NIH had been 40% smaller? Replaying history with less NIH funding shows widespread impacts on drug-linked research

This paper does a great job with a "It's a Wonderful Life" scenario about NIH, supposing the consequences of the bottom 40% of the funding NIH grants never existed.
