The changes in cytoplasmic ion concentration orchestrate global cellular dynamics through wire-like ion fluxes along pre-existing and self-assembling cytoskeleton to engage the ER mitochondria, & nucleus.

Looking to hire a postdoc to do AI-designed biology with Michael Levin and myself.

Please RT; DM if interested.

Here's what happened the last time we teamed up:

Some interesting stuff at this channel:

including yesterday's panel session

'After Babel: Talking to Aliens & the Mathematics of Communication'

New commentary, Chris Fields and I:

Weird thread on logic gates:

We all know and love the XOR gate. Synergy! But here's a weird link to the AND gate.

Let's create a 'meta gate' that describes whether we can compute the correct answer for the XOR gate given the inputs... 1/N

I have no doubt this will be very worthwhile:

Prompted by wjmccartan-Billy, I updated my insufficient words about Dan Dennett
thoughtforms.life/farewell-dan-d… with audio of a talk by him in our lab,
I have no video, but if you scroll down to the end of the post, there is now a link to an audio recording of a lecture he gave; ~ hour

Any ideas for a good peer-reviewed journal that takes full-length (8K+ words) Perspective pieces relevant to AI, biology, cognition, and society?

A really interesting, detailed talk given to our group by Joscha Bach : Cyber Animism

(sorry for the first version I uploaded and had to take down, turns out that zoom somehow added a 2nd, blank audio track and it was killing the sound)

Some thoughts on AI and related issues, from the perspective of Diverse Intelligence:

It’s amazing how many empirical features of interactions and collective response can emerge from a simple imperative: to minimize surprise.

Paper! Imagine walking on the floor with your hands…We made this for living tissues using E-cadherin (cell handshake protein). Cells treat the floor as a giant cell and ‘get weird’—>new biomedical material! Hurray KevinSuh*/ElenaCho*,Isaac Breinyn. doi.org/10.1016/j.celr…! 🧵

Michael Levin and I are at it again! :-)
