I am happy to share a new preprint with Daecheol Kim, Yefei Zhang, and Yuxuan Zhao on The Keller-Segel Model for Chemotaxis on Metapopulation Graphs and Graphons. In this paper, we explore spatial pattern formation through directed motion on patch-structured populations. arxiv.org/abs/2610.31049

arxiv.orgThe Keller-Segel Model for Chemotaxis on Metapopulation Graphs and GraphonsMany models of spatial populations use directed motion towards environmental attractants as a mechanism for spatial pattern formation. While prior approaches typically focus on partial differential eq...

Please RT: Do you use math to address interesting biological problems? Join us at Vanderbilt BioSci! We are conducting an open-rank TT search in Theoretical Biology: apply.interfolio.com/194619. We are a friendly and collaborative department with interests spanning a range of biological disciplines!

Port Richmond Station, Philadelphia, 1925. Coal unloaded from Delaware barges. Firemen watched twelve stoker fires through peepholes. Oilers judged bearings by bare palm, every pipe clad in asbestos. Turbines ran 24/7 under the 125-vaulted ceiling; for 60 years.

Why do societies rely on rigid moral rules? Don't lie. Keep your promises. Don't steal. We all recognize there are good reasons to make exceptions. So why are moral rules so often categorical? Our new paper proposes an answer. 🧵

And, here, in much more detail. This is an absolutely critical read for all federally funded scientists and institutions. Now is not the time to sit in the corner, hoping you won't be noticed - now is the time for action. elizabethginexi.substack.com/p/summary-of...

New paper out in Proceedings of the Royal Society B: we apply linguistic tools to sperm whale vowels. The result: sperm whale vowels do not just look like human vowels. They also behave like them. We found several parallels. Like in Latin, whales have short and long vowels.

We are recruiting 1-2 postdoctoral fellows to investigate the specificity of human anti-influenza virus antibodies, and to determine how these antibodies impact global antigenic drift of influenza viruses. Join our lab at Penn in Philly. Reach out if you are interested in applying! Please repost!

The last time I tried to engage with Jay Bhattacharya in dialogue I ended up on administrative leave. 🤷‍♀️

Katy Milkman@katymilkman.bsky.social

To everyone responding with vitriol: please come! Our goal in choosing speakers was to platform both popular and unpopular figures advocating for scientific reforms to spark productive conversations across divides! If this makes you angry, come engage in dialogue — that’s how we improve.
