More than timber: Wohlleben, Stamets and Rosolie on the value of old forests

Peter Wohlleben describes a forest as a cooperative community with mother trees that grow slowly and share food, Paul Stamets presents the agarikon, an old-growth forest mushroom that can live for a century, as part of an old-growth library, and Paul Rosolie tells how an expedition stumbled onto untouched ancient forest beside a freshly cut logging road. Side by side, their accounts give readers reasons to value old forests for more than their timber.

Bearing witness: how exposing atrocity can move the world, and when it fails

Solzhenitsyn's secretly written Gulag Archipelago, the insurance lawsuit that exposed the Zorg massacre, Skye Fitzgerald's films and Gareth Jones's reporting on the Holodomor show how documenting abuse has broken official silence and helped spark change. Michael Malice's account of the journalists who denied the famine, and Norman Naimark's and Fitzgerald's warnings about atrocities that continue in plain view, show that the record can be suppressed or ignored, and that witness works only when people act on it.

Famine as a weapon: from Stalin's Holodomor to Yemen's hunger wards

Norman Naimark explains the Holodomor, Stalin's terror famine in Ukraine, and what counts as genocide, Michael Malice tells the story of the Holodomor and the journalists who looked away, and Skye Fitzgerald describes hunger as a weapon of war in Yemen and the political decisions behind it. Seen together, they show that mass starvation can be a choice made by people in power, which changes who should be held responsible for it.

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.

Racing mind at bedtime: wind-down rituals that quiet the brain

Rebecca Robbins, Mel Robbins, Gina Poe and Walker each recommend a deliberate buffer before bed, from a fixed wind-down ritual to phrases and tasks that get the mind off itself. The common thread is that sleep cannot be forced, only prepared for.

Too much sleep: when long nights are a warning sign

Walker and Attia both address oversleeping, noting that very long sleep is often a marker of poor sleep quality, illness or depression. It corrects the idea that more time in bed is always better.

Behaviors first, then magnesium, apigenin and theanine: the sleep supplement order

Huberman's sleep toolkit and supplement framework and Walker's review of the evidence agree that supplements come after light, timing and temperature, and that the options should be tried one at a time. It gives readers a sober way to judge sleep products without relying on melatonin.

Sleeping on a problem: how dreams and REM produce creative answers

Walker, Poe, Jandial and Rick Rubin describe sleep as a state in which the brain links distant ideas, which is why solutions and new ideas often appear after a night's sleep or on waking. It gives creative workers a reason to capture ideas on waking and to schedule hard problems before sleep.

Dire wolves, thylacines and Ice Age bones: the pull of lost species

Forrest Galante explains why the thylacine and other lost species matter, Harland Williams and Joe Rogan discuss hybrid experiments and dire wolves, and John Reeves describes the Ice Age fossils coming out of Alaska's permafrost and his fight with a museum over them. Extinct animals hold a strong grip on the imagination, and these conversations show what that fascination can do for science and where it leads to disputes.

Following the money in conservation and climate: where spending helps

Forrest Galante criticizes broken conservation science and questions billionaire projects such as mosquito nets, Cameron Hanes follows the money through nonprofits and politics, and Bjørn Lomborg and Andrew Revkin weigh the cost of climate policy against better ways to spend. Each argues that good intentions and large budgets often miss the target, so the question for donors and voters is what the money buys.

Self-hypnosis for insomnia: a tool for falling back asleep

Psychiatrist David Spiegel describes clinical hypnosis as a way to calm the body and return to sleep, and Huberman uses hypnosis as a deliberate rest tool in his own routine. It offers a drug-free option for people whose problem is an overactive mind at night.

How to get more deep sleep: the few things that move it

Huberman's answers on slow-wave sleep and Walker's account of what deep sleep does point to the same short list: remove alcohol, late caffeine and late meals, time exercise well and keep the timing of sleep steady. Deep sleep carries growth hormone release and physical repair, so it is worth protecting directly.

Alone at the edge: what solitary fieldwork teaches scientists and explorers

Diane Boyd lived alone in the wilderness during her wolf research, Paul Rosolie describes surviving the jungle alone and getting lost in it, and Nathalie Cabrol recounts diving volcanic lakes at 20,000 feet and living through an earthquake on a volcano. Their accounts show what isolation and real danger demand of a researcher, and why some of the most important field knowledge is gathered that way.

When you train shapes how you sleep: exercise timing rules

Andy Galpin, Walker, Hattar and Huberman discuss how morning or afternoon exercise supports sleep while late, stimulant-fueled sessions can delay it. For people who can only train at night, they describe how to limit the damage.

Don't Trust Your Sleep Score Too Much: Poe, Huberman and Attia on Trackers

Gina Poe and Andrew Huberman say consumer trackers only estimate sleep stages, about 70% accurate at best, and that the score itself changes how rested people feel the next day. All three still use trackers, and advise reading the numbers as averages and prompts to adjust habits, next to how your body actually feels.

Eating what you hunt and catch: wild game, bear meat and contaminated fish

Luke Bryan talks about cooking wild game, Cameron Hanes about bear meat, Steven Rinella about mercury and arsenic in wild fish, and Paul Rosolie contrasts local jungle diets with America's food system. Together they show wild food as both a real alternative and something with its own risks that eaters should understand.

Is six hours enough, and can you recover from years of short sleep?

In live Q&As and with Walker, Huberman takes up how much sleep individuals really need, whether lost sleep can be made up and what improves after years of short nights. The answers replace a single eight-hour rule with a way to judge personal need.

No sunrise, no problem: getting morning light in dark winters

Huberman's Q&As and his daily-routine episodes and pulmonologist Roger Seheult address what to do when the sun is not up or winter days are short, from bright artificial light to getting outside whenever daylight arrives. It keeps the morning light habit workable for people at high latitudes and early risers.
