Starting my morning with some light reading of “The Body Electric” by Robert O. Becker.

Timing plays a crucial role apparently in the way that an amputated limb regenerates.

An experiment was done where the Blastema (the embryonic-like cell growth that stimulates regeneration) was transplanted from a salamander, first early on and then at a later stage of development. If the Blastema formed on the forearm for 5-7 days and was then transplanted to the leg, it would actually produce a leg. However, if the Blastema was allowed to develop for a longer period before being transplanted to the leg, it would reproduce a forearm instead.

Really interesting and cool stuff here. This reminds me a bit of how young children are able to learn languages better early on in life. I guess you could say that about learning anything - earlier is often better.
