Preprint time! This is a cool one. Complex systems, be they neural nets, interacting genes, or power grids, can produce diverse dynamics-- things like point attractors, limit cycles, and chaos. The dynamic landscape you get depends on how elements interact. But those interactions can also change!

Today was my last day at NIH after 11 years. I grew up nearby, did summer research, and returned “home” to start my lab. I always thought I’d retire from NIH. But with (lots of!) mixed emotions, and many thanks to my amazing lab and colleagues, I’m saying goodbye 🌸 -> 🍁

Bsky hivemind: what are we liking for Xenium cell type classifiers these days? Have tried RCTD, tangram, and label transfer. 50% of the dataset is easy to classify, but wildly different results across classifiers for the other 50%. +1 if anyone’s specifically fought with spinal cord data. Thx!

One of my favorite rhetorical and analytical moves is joining things (showing that different, seemingly unrelated ideas are part of the same phenomenon) and taking them apart (resolving paradoxes by demonstrating that what appears like a contradictory thing is different things, lumped together). 1/
