Check out our preprint investigating host use in sympatric Caenorhabditis nematodes! We found three Caenorhabditis species in a local community are associated with different invert taxa, and document a strong association between one species and invasive nitidulid beetles.

It's horrific but also this is pretty much a regular arrest. That's how violent arrests are. I am glad people can see it and be horrified -- that's what police are out there doing every day, legally. Every 3 seconds basically.
New video shows ICE agents detaining a US citizen legal observer in Minneapolis.
The agents smashed his car window, dragged him out, and placed a knee on his neck.

One of the biggest tells of gen-AI ants is the waist.
I think this is because most ants belong to one of two subfamilies- Myrmicinae and Formicinae- that have very different waist structures, but the algorithms often average them into fake ants in a non-existent morphospace in between.
