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...

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 don’t neural networks learn all at once, but instead progress from simple to complex solutions? And what does “simple” 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...

Infants organise their visual world into categories at two-months-old! So happy to see these results published - congratulations Cliona and the rest of the FOUNDCOG team.
1/7 Can infants recognise the world around them? 👶🧠 As part of the FOUNDCOG project, we scanned 134 awake infants using fMRI. Published today in Nature Neuroscience, our research reveals 2-month-old infants already possess complex visual representations in VVC that align with DNNs.

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

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

On a recent January evening, security forces began firing into a crowd of demonstrators in Mashhad, Iran. “I saw an eight-year-old child who was shot in the chest,” a pediatrician said. “This regime has no sense of humanity.” www.newyorker.com/news/as-told...
