Write your program officer and grants management official TODAY and thank them! It takes 30 seconds and its really appreciated. The only reason they're remotely this close is because those folks are working 60 hour weeks under immense pressure
Here are data on the percentage of FY2024 appropriation committed to date in FY2025. Most ICs are well on track, but four ICs (NIMHD, NINR, NHLBI, NHGRI) still appear to be under 80%.
Note that values >100% reflect either a higher appropriation for FY25 or an increased % devoted to grants.

🎉Check out our new preprint!! 🧬We found that lamin mutations in muscular dystrophy don’t just affect the nucleus — they disrupt a nucleolar–ribosomal axis that reorganizes the entire cytoplasm.
Very grateful to @danstarrucdavis.bsky.social, @gwgl.bsky.social and our lab for collaboration & support!

figured out why muscular dystrophy mutations cause such widespread cellular chaos. The answer wasn't what we expected - and it changes how we think about the disease. Thread🧵 (1/6). www.biorxiv.org/content/10.1...

Centrosomes might look tough, but they are actually big softies - see the latest work from the Dammermann lab now on BioRxiv:
1/6 Extremely happy to share my PhD work is out on bioRxiv! We discovered that microtubules deform mitotic centrosomes. When we removed them, the SPD-5 scaffold became denser but didn't lose material. This suggests it's an elastically deformable solid! This only happens in mitosis.
