Ok now we have recognized optogenetics, which massively deserved that Nobel medal. Next on the list is dopamine, right? Wolfram Schultz and colleagues have changed our understanding of the brain and mind to the point that dopamine/reward are now part of popular culture (and for the right reasons).

UAI 2026 paper: A genetic perturbation can change the connectome, a new policy can rewire economic links between firms. In each case, interventions change the graph itself which standard SCMs treat as fixed. We tackle this in Partially Observed Structural Causal Models (POSCMs).
Expanded DAG for a 3-node POSCM under ordered generation. An exogenous ordering τ feeds context variables β₁, β₂, β₃; each βᵢ generates adjacency variables A_ji, which gate the value channels between endogenous variables V₁, V₂, V₃ and also feed the mechanism variables f₁, f₂, f₃. Phase I covers structure and context generation; Phase II covers mechanism assignment and value generation.

One highlight: brain energy use is remarkably stable across rest & active engagement. "Rest" isn't idling like a car at a stoplight; it's replay, consolidation. So real efficiency gains could come not from powering down, but from making offline processing do more to *globally* maximize efficiency.

p-values are widely misused. Goodman has a "dirty dozen" list of misconceptions. Two common ones: "p = 0.05 means the null has a 5% chance of being true" (no — that's a posterior, not a likelihood) and "p > 0.05 lets us accept the null" (also no — failing to reject ≠ evidence for).
