Code is written for people: Knuth, Guido and the Hitchhiker's Guide on readability

Donald Knuth explains in two conversations why he writes programs as literature through literate programming, Guido van Rossum describes programs as recipes written for two audiences and digs into code readability, and The Hitchhiker's Guide to Python devotes its core chapters to writing and reading great code. Treating the human reader as the main audience changes how programmers name, structure and explain their work, and makes code easier to maintain.

Melatonin as the body's calendar: light, seasons and mood

Andrew Huberman's light episodes describe melatonin as the body's seasonal calendar, his episode on time perception calls circannual entrainment a calendar written in melatonin, his office-hours answers link seasons, melatonin, serotonin and mood, and Samer Hattar takes up night waking, melatonin and seasons with him. Seeing melatonin as a signal of the time of year, not just a sleep switch, helps explain why mood shifts with the seasons.

Turning Back the Clock: Age Reversal, Escape Velocity and What Is Actually Proven

David Sinclair reports that a cellular reprogramming therapy has entered its first human trial, Ray Kurzweil forecasts more than a year of added life expectancy per year by the end of the decade, and Nick Bostrom and Michael Levin add what ending aging would demand and another biological route to it. The sources contain no outside critic of these claims, so this piece sorts each one by its evidence: shown in animals, shown in human cells, under test in people, or still a prediction.

Your mouth is a health organ: oral bacteria, fluoride and whole-body disease

Dentist Staci Whitman and Huberman's oral health episode treat the mouth as a living ecosystem that teeth repair within, and warn that harsh mouthwash and constant snacking damage it, while James Nestor ties shrinking jaws to breathing problems. Looking after the mouth turns out to protect far more than teeth.

Growth hormone: the youth hormone that may not lengthen life

Clinics offer growth hormone and drugs that release it to restore youthful muscle and skin, and Kyle Gillett and Craig Koniver describe using them, yet David Sinclair notes that lower growth signaling goes with longer life and Huberman lists the risks of injecting it. The contrast shows why feeling younger and living longer are not always the same goal.

Honest machines: why labelling AI as AI is necessary and not enough

Yuval Noah Harari wants AI that poses as human banned, and Anthropic's Amanda Askell says models should always be honest about what they are. Kate Darling and Rana el Kaliouby show why a label alone falls short: people bond with machines they know are machines, so honesty also has to cover whose interests a system serves and what it can really do.

Can a machine be conscious? Physicists, philosophers and builders disagree

Harari separates intelligence from consciousness, Penrose argues understanding cannot be computed, Tegmark calls consciousness information processing, and Thomas Campbell and Joe Rogan treat today's AIs as possibly aware. Laying the positions side by side shows what each would count as evidence, which matters once people start asking whether AI systems deserve moral consideration.
