Xenobots 101 - skin and heart cells

Here’s a new fact of life, that should make for some interesting talk.

This is happening.

It’s amazing the tricks human ingenuity can figure out.
Sad thing is, I don’t see where we’ve learned anything from this ever increasing power and ‘mastery’ of nature’s tiniest components.

Still, truly amazing. I’m a simple human struggling with regular daily life and see all this from that street level perspective.
I’m sure with plenty of free time to devote to studying it closer, my outlooks would evolve. But the reality of our collective failures as reflected in current events (globally and historically) puts the tarnish on all the pride others take in this.

When it comes to living and life, we still don’t know our arses from our heads.
We don’t know what to do with all this knowledge and tinkering we’re frantic avariciously stuffing into our heads.
Or? . . .

Xenobots—living robots made from the stem cells of the African frog ( Xenopus laevis )—had already impressed researchers by moving, healing themselves, and even spontaneously piling up debris that was strewn about. But when those small synthetic particles were replaced with loose stem cells, the little living bots did something remarkable: they brought those cells together, constructing new xenobots.

“These are frog cells replicating in a way that is very different from how frogs do it. No animal or plant known to science replicates in this way,” Harvard University synthetic biologist and roboticist Sam Kriegman, co-lead author on the PNAS paper describing the discovery, says in a press release from Harvard University’s Wyss Institute.

Xenobots were first born when scientists extracted skin stem cells from frog embryos and cultured them in salt water. …

Is this proof of the functional abilities of microtubules? The one common denominator of mitosis in all Eukaryotic organism are microtubules.

Are microtubules found in prokaryotic or eukaryotic cells? 2022 - Question & Answers (hardquestionstoanswer.com)

AFAIK only some prokaryote bacteria and viruses do not use microtubules for genetic transcription and cell division.

Does this prove that microtubules can be used for manufacturing biological organisms? Cell division is one of the required properties of living things. If we can introduce chromosomes into cells we might be able to grow all kinds of organs.

Yes I saw this too a couple of months ago I think.
But I don’t agree with your assessment that we haven’t learned anything from science and our reasoning though.
The quality of life we live now is better than any other previous time in history and unless we annihilate ourselves or go back to a stone-age era from a nuclear war or disaster , then the quality of life will only increase.

It sounds to me that you APPRECIATE this (science and human ingenuity ) more than others, just like I appreciate God more than others.

I see what you, sure, there’s much we’ve learned, yet,
I was referring to an existential awareness, along with appreciation for Earth’s evolution and how much that has to do with who we are and the world we live in.

That appreciation for the Human Mindscape ~ Physical Reality divide.

Yet most take it for granted - and too many seem blind beyond bling and consumption, and playing the big shot. Totally missing the finer points of living a human life, and how fantastically well we have it these days.

I also have a deep appreciation for God. Though I’ve learned to appreciate that all our God’s are created from within our human psyche. Much like science and human ingenuity.

I’ve got my mom to thank.
