Skip your daily nap, shrink your brain. A study by researchers from University College London and the University of the Republic in Uruguay has found that people who habitually take daytime naps tend to have significantly larger total brain volume—a key indicator of brain health that typically declines with age and is associated with reduced dementia risk. The team used Mendelian randomization, a method that leverages genetic variants (present from birth) that make people more likely to nap regularly. By analyzing brain MRI scans and health records from more than 35,000 participants in the UK Biobank, they discovered that those genetically inclined to nap had brain volumes corresponding to 2.6 to 6.5 fewer years of aging. While this doesn’t definitively prove that napping itself enlarges the brain, the genetic approach helps rule out many lifestyle-related confounding factors, providing stronger evidence of a potential causal relationship than traditional observational studies. Notably, the researchers found no link between napping predisposition and performance on tests of reaction time, memory, or visual processing. However, previous studies have shown that short naps can deliver immediate cognitive benefits. The study lacked specific data on nap duration, but prior research suggests naps of 30 minutes or less provide the greatest advantages while minimizing disruption to nighttime sleep. This is the largest study to date linking regular napping with brain structure. Although further research is needed in more diverse populations, the findings bolster the idea that a brief daytime rest may help preserve brain volume and support long-term cognitive health.

Everyone's excited about Karpathy's autoresearch that automates the experiment loop. We automated the whole damn thing. Meet AutoResearchClaw: one message in, full conference paper out. Real experiments. Real citations. Real code. No human in the loop. One message in → full paper out. Here's what happens in between: Raids arXiv & Semantic Scholar, digests 50+ papers in minutes Three AI agents FIGHT over the best hypothesis (one swings big, one sanity-checks, one tries to kill every idea) Writes experiment code from scratch, adapts to your hardware Code crashes at 3am? It reads the stack trace, rewrites the fix, keeps going Results weak? It pivots to entirely new hypotheses and starts over Drafts a full paper with citations, every single one verified against live databases No babysitting. No Slack messages. No "hey can you re-run this." Karpathy built the experiment loop. We built the whole lab. Chat an idea. Get a paper. Try it : https:// github.com/aiming-lab/Aut oResearchClaw … Kudos to the team @JiaqiLiu835914 , @richardxp888 , @lillianwei423 , @StephenQS0710 , @Xinyu2ML , @HaoqinT , @zhengop , @cihangxie , @dingmyu , and we are looking for more contributors.
