Artificial intelligence may write award-winning essays and diagnose disease with remarkable accuracy, but biological brains still hold the upper hand in at least one crucial domain: flexibility.

If you’re not using AI tools like NotebookLM to capture knowledge fields and build out your own “brain,” you’re missing out in a big way. The idea of a “second brain” has inspired millions of people ...

Princeton researchers found that the brain excels at learning because it reuses modular “cognitive blocks” across many tasks. Monkeys switching between visual categorization challenges revealed that ...

Last week, I wrote a post about how high-intensity aerobic exercise can stimulate the release of brain-derived neurotrophic factor (BDNF), a protein that's often described as Miracle-Gro for the brain ...

Princeton researchers found that a primate’s prefrontal cortex reuses modular “cognitive Legos” to solve related tasks, giving biological brains a flexibility that AI still lacks. The insight could ...
