	Found a quite interesting paper on evolution, aging, and mice as a biomedical test model: sciencedirect.com/science/articl… from an also interesting (long) podcast episode: stitcher.com/podcast/kast-m…

	Odgovor korisniku/ci @pranavpark A lot of it is the "age" of the head (time from induction) - they get more dominant as they mature.

	Odgovor korisniku/ci @MmkWazir Planaria are not an expensive system, comparatively. That part is relatively easy. But, behavior experiments are quite tricky, and state of the art molecular neuroscience techniques aren’t cheap. If you have a solid plan, a typical grant would cover it, I guess.

	Odgovor korisniku/ci @alexbortvinlab Depends on origin. Cut middle from 2-headed parent - the 2 new heads are basically equivalent. But if induce an ectopic head in presence of mature head, the mature one is dominant and the new one takes time to spread its influence. Mechanism here: biorxiv.org/content/10.110…

	Here's one of the long-form essays on Causation in biology expanding on nature.com/articles/s4158…: "Biophysics of Regenerative Repair Suggests New Perspectives on Biological Causation": onlinelibrary.wiley.com/doi/full/10.10… Others' (like @yoginho's) should be out soon in forthcoming collection. pic.twitter.com/e2dKaqWvw9

	Odgovor korisniku/ci @IntuitMachine I suspect it's (also) related to plasticity of body to maintain robustness despite developmental change (mutations, parasites, and now, experimental manipulations). Ectopic organs often end up very functional: jeb.biologists.org/content/216/6/… The brain can recognize and use ectopic eyes!

	What model systems’ embryos are easily dissociated into cells? Chemical method, ideally (not manual dissection), and we want the cells to stay alive (not for fixation). Can zebrafish? C. elegans? Other invertebrates? The weirder the better. Ideas?

	Rubber Hand Illusion youtube.com/watch?v=TCQbyg… & more generally en.wikipedia.org/wiki/Body_tran… Isn't it weird that despite long evolutionary time of dependable (constant) body structure, brain is willing to abandon default, & revise somatic self-model after mere ~20 minutes of experience?

	Odgovor korisniku/ci @bliss_wander @dakami Code & data = long topic, but I can point to interesting example of tissues keeping counterfactual information = representation of goal state to pursue in future. Relevant, as any state of tissue *now* suggests "no separate data". But alternative happens: authors.elsevier.com/sd/article/S00…

	Before very important Jan. event, told myself "no thinking about new directions until all prep is done & we get past it." Oddly, this triggered flood of new ideas (written down for later). Is this a known thing? What strategies do you all use for enhancing actionable creativity? pic.twitter.com/zKkejF932T
