Why did consciousness evolve at all? A superb special issue of @royalsocietypublishing.org brings together experts across disciplines to explore the functions of consciousness and why it emerged in some species but not others. @tecumsehfitch.bsky.social royalsocietypublishing.org/rstb/issue/3...

Could the logic of life be shaped by the architecture of biological circuitry? In this paper, @manlius.bsky.social shows how genetic, metabolic, and social networks can govern slow evolutionary dynamics in a unified nonequilibrium framework. iopscience.iop.org/article/10.1...

The evolutionary potential of symbiosis Abstract. Symbiosis is considered a source of evolutionary innovation. Example innovations that have evolved in symbioses include new organs, morphological

New perspective on the evolutionary potential of symbiotic interactions!

Is there something special about symbiosis that leads to new traits and adaptations? If so, how would we know and how would this work?

Why donโ€™t neural networks learn all at once, but instead progress from simple to complex solutions? And what does โ€œsimpleโ€ even mean across different neural network architectures?

Iranians are experiencing a collective trauma. Thousands have been killed/injured in recent events, the economy is crippled & the threat of a wider conflict is real. This is especially difficult for those living in Iran, as many have lost (or fear losing) loved ones. www.nature.com/articles/d41...

Are episodic and semantic memory really that different? Using closely matched tasks, we found no substantial neural differences between recalling personal experiences and general knowledge: https://www.nature.com/articles/s41562-025-02390-4

This is what an engineer would typically do: to build a robot, one would design perception modules, typically one per sensory modality, planning modules, and motor control modules (but see Brooks (1986) for an alternative way of building robots). The reasons for this modularity are cognitive and social. Cognitively, this allows one to focus on one simple problem at a time, following Descartesโ€™ rule of analysis (Descartes, 1637): to divide the problem into smaller, more intelligible, pieces ("Diviser chacune des difficultรฉs que j'examinerais, en autant de parcelles qu'il se pourrait et qu'il serait requis pour les mieux rรฉsoudre"). Socially, it also allows work to be divided between different people, or even different companies: one in charge of each module. These modules can then be reused in different contexts, different machines that combine modules in new ways. For this to work, the input-output properties of modules are well-specified, for example by stating that a moduleโ€™s output represents sound direction. What the output represents should not depend on the context in which the module is embedded.
Thus, there are excellent reasons for engineers to use modular design. But brains are not made by people, let alone by human societies. However appealing the functional argument for computational modularity might be, it is hard to reconcile with the known physiology and anatomy of nervous systems.

Brain modularity is a concept inspired by how we make machines. But brains are not made by people.

We could all use some extra stress #resilience rn. But how does it work in the brain? On the surface, resilience looks like ignoring stress. Does the brain fail to respond? Or are active adaptations required? Or are resilience and susceptibility divergent paths? doi.org/10.1016/j.celrep.2025.116867

A bird's-eye view of a former Auschwitz II-Birkenau camp showing a wide dirt pathway flanked by parallel rows of barbed-wire fences. Groups of visitors walk along the path, surrounded by the remnants of brick structures and barracks, now reduced to foundations. Green grass contrasts with the somber history of the site, as the path leads toward a guard tower in the distance.

Auschwitz was at the end of a process. We must remember that it did not start from gas chambers.

This hatred gradually developed: from ideas, words, stereotypes & prejudice through legal exclusion, dehumanization & escalating violence... to systematic and industrial murder.

Auschwitz took time.
