Check out this really interesting preprint by @shikharabhat.bsky.social and @kokkonut.bsky.social on models of senescence and their connection to models of multilevel selection. It seems like these fun jump processes, PDEs, and SPDEs arise in a variety of biological contexts.

So were we! A short explainer thread below
