Our new paper on the distribution of the benthic ctenophore Vallicula integrates diverse observations (iNAT, literature, museum specimens, and eDNA metabarcodes) to show that Vallicula multiformis is circumtropical to subtropical. onlinelibrary.wiley.com/doi/10.1111/...

New paper in Systematic Biology! We show how micro-synteny can help resolve a tricky fish #phylogenetic problem where traditional sequence-based analyses fall short. Genomes archive evolutionary history in more than just their basepairs. doi.org/10.1093/sysb... #fish #genomics #evolution

In addition to the terminations of existing awards, new NSF grants are still stopped completely since DOGE was granted access to systems a week ago. Last Thursday, an agency spokesperson said "NSF continues to issue awards." That does not appear to be the case.

Graph of NSF awards. Compares April 2024 to April 2025, which levels off.

“They apparently just sort of walked past security and said: ‘Get out of my way,’ and they’re looking for access for the IT systems, as they have in other agencies,” said a former Noaa official. “They will have access to the entire computer system, a lot of which is confidential information.”

I hope federally funded scientists are preparing for large scale, bad faith attacks by Musk and his troll army. It’s pretty clear the DOGE operation is going to take snippets of grant proposals and papers, present them out of context, and direct weaponized harassment of individual people.

Elon Musk takes far more federal dollars with far less oversight than any of the public scientists facing attacks. People who come under attack should respond by making sure anyone listening knows how much federal money Musk makes, and how he shields it from scrutiny.
