🧠 New preprint by Codol et al. (2025): Brain-like #NeuralDynamics for #behavioral control develop through #ReinforcementLearning. They show that only #RL, not #SupervisedLearning, yields neural activity geometries & dynamics matching monkey #MotorCortex recordings. RL-trained #RNNs operate at the edge of #chaos, reproduce adaptive reorganization under #visuomotor rotation, and require realistic limb #biomechanics to achieve brain-like control.

The most accurate carotid artery model to date — the first to capture both the soft, low-pressure behavior and the stiff, high-pressure response of the vessel.
Built on the same principles as Fung’s law, but improved: our 2014 α–β framework fits strain energy first, then derives pressure — like how F = dE/dx gives the force in a spring. Here E is the strain energy — the quantity Fung’s law was originally built around. Strain energy is differentiated to give force, and in the fits below that force corresponds to pressure.
The 1987 plot below (Fung-type) fits well only at high pressures; the 2019 plot fits low pressures. Ours is the first to capture both perfectly.

🪲💧 Ripple #bugs live their entire lives on the surface of streams, pivoting in less than the blink of an eye while stirring the #water beneath them into swirling vortices.
#Biomechanics researcher Víctor Ortega-Jiménez spent five years figuring out their secret: feather-like oars on their middle legs that deploy and collapse in just 10 milliseconds. Engineers are now building small #robots that mimic these water-skating abilities.
