National Sleep Foundation — 2025 Annual Sleep in America Poll
The National Sleep Foundation’s annual poll, covering 4,800 adults across six countries, paints a concerning picture: 62% of adults report their sleep needs are not being met on weeknights, up from 45% in 2019. The report includes country-by-country breakdowns, age and gender analysis, and practical recommendations.
Dr. Matthew Walker, professor of neuroscience at UC Berkeley and author of Why We Sleep, joins us for a wide-ranging conversation about what happens in the brain during sleep, why modern life is destroying our sleep quality, and practical steps anyone can take tonight.
This is essential listening for anyone who has ever felt tired — which is to say, everyone.
“Talk is cheap. Show me the code.”
— Linus Torvalds, creator of Linux and Git
Torvalds made this remark during a keynote at the Open Source Summit, pushing back on what he calls “vaporware culture” in the AI space. The full interview covers his views on Rust in the Linux kernel, AI-assisted code generation, and why he still uses a custom email client from 1991.

A 20-year longitudinal study tracking 11,000 adults has found that those who consumed more than four servings of ultra-processed food per day showed cognitive decline equivalent to four years of accelerated ageing by their late fifties.
A new generation of performance scientists is reshaping how professional sports teams approach recovery. FC Barcelona’s recovery team reports that players who average 9.5 hours of sleep make 34% fewer errors in high-pressure match situations. The NBA’s elite teams have restructured travel schedules entirely around sleep quality.
When Meta released Llama 3 weights publicly last spring, few predicted it would catalyse such a dramatic shift in the AI landscape. Within three months, over 4,000 derivative models appeared on HuggingFace. Startups are now building production products on fine-tuned Llama 3 variants at a fraction of the cost of GPT-4 API calls.
