Didn't Robert O Becker also explored this space?

Yeah, AFAIK Becker's "The Body Electric: Electromagnetism and the Foundation of Life" is pretty much all there was until Michael Levin came along and picked up the torch. IMO it's one of those weird "holes": why so little interest in human tissue regeneration?

There's this HN comment I've always found interesting: https://news.ycombinator.com/item?id=32744294

This technology doesn't seem to be limited to existing limbs and organs. After replacing a missing arm you could add a third arm. A man could grow a uterus since he has the X chromosomes and with a transplant that includes Y chromosomes, a woman could grow testes. Parthenogenesis could become a choice. Another head seems possible. The limits are more likely to come from regulation than a reluctance of people to trans…

But it would cost you an arm and a leg. At least initially.

Now there's a future society you don't see written about: a standard part of a marriage is the partners exchange immune-compatibilized gonads with their genetic material, so if one partner dies the other still retains the ability to grow viable off-spring from the pairing.

Isn't this already possible by freezing eggs or sperms?

"Ma'am, I'm here to enforce the terms of the divorce agreement. I need you to take his gonads out of your purse and hand them over."

I mean I imagined it would be like, having them surgically implanted somewhere near the kidney's (large blood supply organ).

Which would make this scenario far more cyberpunk.

So, in other words, if this technology pans out, this could be possible https://mortalkombat.fandom.com/wiki/Goro

This implies that your brain could handle 4 arms. Chances are they would just be dead limbs.

Obviously we can grow an extra brain that will operate the extra limbs.

Is this related to any new research? I’ve been interested in this stuff for a while, but this just looks like a rehashing of previous work.

--My question as well. Am I missing a published date on this podcast? It’s my first time seeing their content. This isn’t their latest episode and I am wondering how recent it is.--

Edit: it’s from April 27, 2023. I did miss it. Says it on the linked page
