I guess any useful material (online workshops, code, libraries, tutorials) for complex systems analysis. Could be network science, dynamical systems, AI even. Weโ€™re just trying to have an up-to-date collection of resources for people so they can learn about these topics themselves.

We're planning to include Netneurotools, Brainspace, Neuromaps, BCT, and Neuromatch, but I was hoping that you have something more general in mind for non-neuro folks.

Pardon a scientist analysis of the war but this outlines why there will be ground (special) forces in Iran to remove โ€œ18 to 20 canisters" containing ~1000 pounds of highly enriched uranium ...unless IRGC surrenders, which if you know the Shia mindset, they never will www.nytimes.com/2026/03/07/o...

Once you get past the first 5 minutes of me bumbling around clearly in need of media training, we settle into a nice groove talking about fitting mechanistic models, ML/AI for neuroscience, underconstrainedness vs. degeneracy, and its potential benefits for biology (plus some good chuckles).

Header and abstract page of an original research article in History and Philosophy of the Life Sciences (2026, volume 48, article 12) titled "Modeling versatility as the hallmark of model organisms," authored by Guido I. Prieto and Alejandro Fรกbregas-Tejeda.

Abstract
In recent years, discussions on the epistemology of model organism-based research have emerged in the philosophy of science. A key topic of discussion is how the epistemic insights gained from model organisms differ from those gained through other experimental organisms used in laboratory and field research. Here, we argue that model organisms are epistemically special due to their nature as ontogenetically changeable, standardized, and evolved material model carriers. These characteristics afford six important kinds of modeling versatility that biologists marshal in their investigations: (i) synchronic target versatility; (ii) synchronic scope versatility; (iii) diachronic target versatility; (iv) diachronic scope versatility; (v) manipulation versatility; and (vi) discovery versatility. In presenting these dimensions of modeling versatility, we also clarify key notions such as โ€˜representational target,โ€™ โ€˜representational scope,โ€™ and โ€˜representational powerโ€™ as these apply to modeling practices that involve model organisms.

It has been argued that what sets model organisms apart from other experimental ๐Ÿ‹๐ŸŒฑ is their high representational power. In our latest ๐Ÿ“ƒ, we argue otherwise: the hallmark of MOs lies in the dimensions of modeling versatility they afford to scientists ๐Ÿ‘‡ link.springer.com/article/10.1... #philsci #HPS

Curious to read the arguments in here (paywalled) because for 4 decades any attempts at even nudging the regime towards normalcy was responded with disproportionate violence. Last time ended with thousands dead within two days so how exactly are we measuring cost that it suddenly got harder *now*?
