How do our bodies know what to become?
There are no instructions in our genes that code for the exact 3D structure of our bodies. There's no tiny human contained in our DNA. So, what powers the transformation of the first cell in the embryo to a full-blown organism?
Dr Michael Levin is attacking this problem and, in the process of answering it, his lab is uncovering an entirely new way of looking at biology.
== What we talk about ==
0:04 - Introduction

1:00:12 - How to program Xenobots
1:05:13 - How do you handle the ethical dilemma while you are working with conscious organisms?
1:10:22 - How do you enable the scientific creativity in your lab and amongst your students? And is it a teachable skill?
== About the guest ==
Michael Levin is a Distinguished Professor in the Biology department at Tufts and serves as director of the Allen Discovery Center. He holds a PhD in biology from the Harvard University. At Tufts, his research group is interested in figuring out how our bodies know what to become.
He believes that what guides our body plans is bio-electric communication between different units. Our bodies take shape the way they have because each of our subunits - cells, tissues, organs - collectively decides it to be that way.

Levin is at a whole different level. Everyone who interviewed him, and everyone who talks about him in interviews and podcasts realise that what we have here is something very special. I don’t think the term genius is in any way exaggerating Levins intellect.

I think we absolutely need to understand the lowest level building blocks of intelligence, so that we can really understand all the other levels of intelligence which build up across a great many levels of increasing complexity and thus our high level intelligence is an incredibly dense swarm intelligence with many onion like layers from our highest level of intelligence down through all the many building blocks.

my takeaway is how difficult it is to overcome prejudice kudos to Dr. Levin for his patience and for his wisdom in deciding "Ok, I've said tis 3 different ways. I need to move forward."

The thing is: what is the physical support for the electric structure mentioned ? is it in proteins? is it genetically determined? or is there a weird " master plan" cells obey?

DNA is directing bio electricity is there a possibility it is partly directed (learning process) by microtubules Stuart Hamerhof and Roger Penrose. In other words do you get changes in your experiments where there is no explanation? You find the mechanism but nothing to trigger the mechanism while you know there is a precedent somewhere in nature so it’s a repeat in nature (memory other than DNA)

I find Mike's ideas very intriguing, but I don't like the impulse to relate everything to computer programming. That is not what's going on. It's something quite different, more along the lines of Wal Thornhill's "Electric Universe Theory".

@Demosophist 2 жыл бұрын

We think of a plasma as a fourth stage of matter. It might be more accurate to say that matter as we perceive it, including biological matter, is a form of plasma, most of which is hidden from our senses.

Imo computer programming is the easiest and most-relatable way our brain interprets his ideas, so he uses the most relatable analogy. In other talks he is making different analogies, so I strongly recommend checking him out!
