Wolpert and Kolchinsky have defined semantic information by framing an agent's ability to maintain itself (autonomous agency) as the ability to remain in a low-entropy state. In this way, having high semantic content is a necessary condition for any physical system to be alive./2

Number of works focused on autopoiesis and (M, R)-systems. Counts are based on the Web of Science. It would be interesting to see if the trend has changed from 2013 to 2024...

However, names like Pattee, Cariani, and Hofmeyr were left out of their scope despite their enormous contributions to the topic. As shown in my latest #complexitycat essay, the first in proposing time to resolve self-reference was Tomek Korbak, not them!/3

Don't get me wrong, the authors did a great job of challenging conventional scientific assumptions and exploring alternative frameworks for understanding living systems, proposing a solution to the paradoxes of self-reference, and outlining new directions for artificial life./2

Last week, #complexitycat brought you a short essay tracing the idea of life as a thermodynamic phenomenon out of equilibrium, discovering that Schrödinger failed to cite relevant contributions when writing his popular “What is Life?”.

Our last keynote speaker at #ALIFE2025 is @annaciaunica.bsky.social, who discussed the importance of bodies when talking about intelligence and agency. Her integrative approach shows that we need to adapt and extend the notion embodiedment to reflect the co-autopoietic nature of life.

How can the physics of the Game of Life be modified to create extended non-equilibrium conditions? What new structures could be created with these changes? Hank Rainwater addresses these questions, showing self-organization and phase transitions in driven CA.

Fernando Rodríguez Vergara uses von Neumann's kinematic automaton as a motivation to distinguish life from computation, being the capacity of adaptation one of the main differences. Algorithms are fixed, substrate-dependent entities lacking organizational closure.

Are there universal laws of life? Our keynote speaker today at #ALIFE2025 is Chris Kempes, who dedicated his talk to the question above. He mainly focused on the constraints that life needs to emerge, showing that there are general scaling laws between multiple biological traits.
