How do #stemcells integrate information to coordinate fate decisions? Delighted to finally see our work showing how growth factors regulate the mechano-osmotic state of the #nucleus and #chromatin to control #pluripotency exit out! www.nature.com/articles/s41... see 🧵 👇
Mechano-osmotic signals control chromatin state and fate transitions in pluripotent stem cells - Nature Cell Biology
McCreery, Stubb et al. show that mechano-osmotic changes in the nucleus induce general transcriptional repression and prime chromatin for cell fate transitions by relieving repression of specific differentiation genes.

The Trump HHS spokesman Andrew Nixon is a flat liar. Peer review selects the best grants and awards them for several years and that’s it.

The Trump admin has politicized American science in an unprecedented way and now lies about it. Journalists: ask scientists about what’s happened for the truth.

URGENT: FlyBase has lost practically all its funding overnight; even user fees are tied up in denied grant funding. 🤬🤯

Any lab using @flybase.bsky.social please donate using the link in post below.

This incredible community, on whose backs our #Drosophila labs depend, can't be left out to dry.
My lab studies bacterial infections. We spend a lot of time looking at (or for) species-specific genetic and genomic databases for hosts and microbes. FlyBase is the best of all—there is literally no comparison. Its existence is under threat. Please donate.

NfL beats GFAP in a head-to-head FTD biomarker competition. Gendron et al. show plasma GFAP and NfL correlate with FTD disorder severity; however, NfL outperforms GFAP as a prognostic biomarker and potential susceptibility marker.

1/ Transposable elements are often called "jumping genes" because they mobilize within genomes. 🧬
But did you know they can also jump 𝘣𝘦𝘵𝘸𝘦𝘦𝘯 cells? 🤯
Our new study reveals how retrotransposons invade the germline directly from somatic cells.
