Super excited about this review/new data preprint on aquatic plant photosynthetic methods - turns out its *hard* to measure stuff underwater! Led by awesome grad in the lab @ellliieee.bsky.social with postdoc @wickellomics.bsky.social and some brilliant people at LiCor! 💧🌿

As we all eagerly (anxiously?) await NSF's release of the 2026 GRFP solicitation, please consider signing up as a mentor for BSA's GRFP workshop. We especially need more senior mentors (PIs, postdocs, and research scientists)!

I got an email yesterday afternoon that my NSF SPRF Postdoctoral Fellowship was terminated. My grant focused on testing interventions to address online misinformation and I was 8 months into a two year appointment.

The first step in generating public support for science is telling people what the heck we're doing and why it matters! If you are a researcher who benefits from federal funding, please consider writing a letter to your local paper: blogs.cornell.edu/asap/events-...

To update people on the NSF PRFB situation: despite the court challenge and rescinding the original memo, the NSF has continued to comply with the executive order. They have not communicated with us at all and our paychecks are still canceled indefinitely. I know people who cannot pay their rent.

We are working on a major update to Mesquite, version 4! We welcome any suggestions for features or fixes. A major emphasis will be phylogenomic data. We may not have time for more big features, but please suggest small features for data maintenance or editing that could make your lives easier.

Our groups' goal is to produce genomes that are useful; this does not always mean 'telomere-to-telomere' assemblies. The hybrid sugarcane genome is a nice example of this. The article is out this week in Nature: www.nature.com/articles/s41...
