What are the preferences of novel in silico and in vivo agents that aren't directly engineered toward a specific set of behaviors? An example, from the world of Lenia (en.wikipedia.org/wiki/Lenia) - here's our #preprint on agnosiophobia (avoidance of the unknown): arxiv.org/abs/2605.30708

I'm not sure about "fast=night science". To me, the fast part describes fitting/learning by heart of things that need to go quickly from the hand. Deep, intuitive insights which you can't put your finger on just yet (creative night science) is more subtle: it's models forming via distributed insight

Indeed Oded. Some Will think of #TCTeAC as escapism, but I think it was showing us how beautiful we can make this world if the guiding values are respect & trust, and if world leaders would adopt a vision that is based on hope instead of hatred. On collaboration instead of competition. 💚

A very short summary of "Data Visualization against fascism": Fascism conceals truths, disregards evidence-based decision-making, and jeopardizes the education of the next generation. Standing up against means: MONITOR, EXPOSE, and EDUCATE. As scientists we are ready for this! #TCTeAC

Let's not be #TCTeAC "The Conference To END All Conferences", but a new format of many more such events. Depating science outside of our typical nutshell (scientifically and mentally) has great potential - we could have come up with 50+ project proposals together. Let's bring fun back to science :)

#TCTeAC - the Woodstock of Biology2 & #nightscience - was such an amazing event!! We met great scientists who creatively presented their high quality work. We dreamt and discussed in a very broad, open-minded setting. Talking science outside of our nutshell can be soo valuable - let's do this again!

Everybody is just talking about the fun #TCTeAC but the high quality of science, across a diverse range of fields, was equally impressive. Thanks to the organizers, such a unique event.

Over the last century, biologists developed a strong model of morphogenesis: the genome defines the microscopic hardware that sets the rules of how cells interact wich leads to the emergence of an organism. We invite you to see this through the lens of collective and generative intelligence.
