The National Science Foundation sign on our Eisenhower Av building is now gone.

The NSF mural in the foyer is removed and torn off in sheets.

We were supposed to celebrate the 75th anniversary of the agency in May 2025. That never happened.

Phylogenomics of Cypriniformes, the most diverse order of freshwater fishes: consensus, challenges and limitations
Cypriniformes, the most species-rich order of freshwater fishes (∼5,000 species), represents a key lineage for understanding vertebrate diversification in freshwater ecosystems. This clade includes several highly miniaturized and understudied lineages whose phylogenetic placements have long remained contentious. Here, we present the first phylogenomic analysis of Cypriniformes with complete family-level representation and broad genus-level coverage, encompassing 316 species comprising approximately 30% of all described genera. Our dataset integrates 257 newly assembled genomes with publicly available resources and analyzes multiple sets of genome-wide markers using both concatenation-based and coalescent-aware approaches. The general concordance among analytical frameworks indicates that the backbone topology of Cypriniformes is now established, allowing clear identification between well-supported clades and regions of persistent conflict. Our results strengthen the evolutionary relationships of several miniaturized lineages, while identifying recalcitrant relationships shaped by both biological processes and model artefacts that can yield superficially similar patterns of phylogenetic conflict. Our study substantially expands genomic representation and establishes a phylogenomic foundation for future comparative, developmental, and evolutionary research in this freshwater radiation. ### Competing Interest Statement The authors have declared no competing interest.

Here's a question to vertebrate paleontologists: aren't chondrichthyan teeth and osteichthyan homologous? I'm reading something suggesting that chondrichthyans might have been present in the Ordovician based on scales, but the probability of failing to find teeth for that long is absurdly low.

When @omearabrian.bsky.social saw the manuscript, he described it as: ‘What if this figure could be an entire paper?’

I choose to interpret that as high praise.

Another eg from a few years ago. I got students to guess the purpose of the berry-like redness of ant abdomen. I then revealed that redness was due to ant parasite & got them to guess again why it would evolve to tigger its host to resemble a berry. newsarchive.berkeley.edu/news/media/r...

For some reason my Monstera pinnatipartita flower developed a colored edge? First time getting this species to bloom so I don't know how it usually is, but pictures online look all white, like it started out, but it developed some color lager.

I know it's probably crazy, but I did indeed check that The Lord of the Rings extended edition trilogy theater re-release is scheduled with 3 showings per day at 3 hour intervals. Since the movies are over three hours long, this makes viewing all three of them in a day impossible.

A spectacle to behold, in the shallows, hugging this island, we see broad cowtail rays and mangrove whiprays - and looking with a close eye, few juvenile blacktip reef sharks weave between the rays.
