This is all well outside my area of expertise, but my impression is that Michael Levin's work with bioelectricity is on the cusp of #6 Somatic limb regeneration.

SMEs please correct the record if I'm mistaken.

Unfamiliar with Levin’s work, but:

There’s also this study [0] I read recently, along a different path of using known growth factors and proteins to kick off regeneration.

		ECM (Extracellular Matrix) has been studied for similar properties: https://www.biorxiv.org/content/10.64898/2026.08.05.742898v1... "Extracellular matrix particle treatment induces digit regeneration in soft-tissue preserved amputation (SPA) model of adult mice"

Everyone interested in biology and intelligence should look up Michaels work, it is amazing because he's ignored a lot of assumptions that are held by the community and come up with new and interesting tests.

Also his work on algorithmic intelligence in cells and the mathematical foundation of intelligence will change many fields, including AI, if it can be empirically tested.
