we propose a new theory of metabolic scaling grounded in thermodynamics and stochastic fluctuations at the cellular level.

Neuronal signatures of successful one-shot memory in mid-level visual cortex

Thinking, Searching, and Acting
A reflection on reasoning models. It's easy to fixate on the "thinking" that gave reasoning models their name, but just over a year out from o1-preview's release by OpenAI, the core primitives that make up models today has expanded.

How does the brain decide? 🧠

Our new @nature.com paper shows that neural activity switches from an 'evidence gathering' to a 'commitment' state at a precise moment we call nTc.

After nTc, new evidence is ignored, revealing a neural marker for the instant when the mind is made up.

Hybridization and introgression are major evolutionary processes. Since the 1940s, the prevailing view has been that they shape plants far more than animals. In our new study (www.science.org/doi/10.1126/...
), we find the opposite: animals exchange genes more, and for longer, than plants

Esoteric languages challenge coders to think way outside the box. In a conversation with @spectrum.ieee.org, author and artist Daniel Temkin dives into the coding exercise/art form. Look for his new book, "Forty-Four Esolangs: The Art of Esoteric Code," later this month:

How do humans learn from arbitrary, abstract goals? We show that, when goal spaces can be compressed, costly working-memory processes give way to internalized reward functions, enabling efficient goal-dependent reinforcement learning. @annecollins.bsky.social arxiv.org/abs/2509.06810
