Ancestor Trouble is one writer’s attempt to use genealogy - a once-niche hobby that has grown into a multi-billion-dollar industry - to expose the secrets and contradictions of her own ancestors, and to argue for the transformational possibilities that reckoning with our ancestors offers all of us.

A comprehensive catalog of the most devastating and deadly events-natural or man-made-in human history. If you follow the news it can seem like injury, sickness, and death are now constant, inescapable occurrences that threaten us every second of every day. But such catastrophic events - as terrible and frightening as they are - have been happening for as long as mankind has walked the Earth.... and even before. From ancient volcanoes and floods to epidemics of cholera and smallpox to Hitler's mass killings in the 20th century, humanity's continued existence has always seemed perilous.

Thousands of religions have adherents today, and countless more have existed throughout history. What accounts for this astonishing diversity?

Founder Ellie Laks started The Gentle Barn after adopting a sick goat from a run-down petting zoo in 1999. Some 200 animals later (including chickens, horses, pigs, cows, rabbits, emus, and more), The Gentle Barn has become an extraordinary nonprofit that brings together a volunteer staff of community members and at-risk teens to rehabilitate abandoned and/or abused animals. My Gentle Barn weaves together the story of how the Barn came to be what it is today with Ellie's own journey.

Rivers, on a long view, are alive. They are born; they change; they shift their channels; they forge new routes to the sea; they move both gradually and violently; they can teem (usually) with life; they may die a quasi-natural death; they are frequently maimed and even murdered. It is the annual flood pulse—the brief time when the river occupies the floodplain—that gives a river its vitality, but it is human engineering that kills it, suppressing the flood pulse with dams, irrigation, siltation, dikes, and levees.

Passengers get bumped from flights. Phone menus disconnect. Automated financial trades produce market collapse. Of all the challenges in modern life, some of the most vexing come from our relationships with automation: a large system does us wrong, and there’s nothing we can do about it. The problem, economist Dan Davies shows, is accountability sinks: systems in which decisions are delegated to a complex rule book or set of standard procedures, making it impossible to identify the source of mistakes when they happen.

In this 2nd episode of We’re All Ears, host Janet Marlow, sound behaviorist and founder of Pet Acoustics, explores how stress affects dogs and cats — not just emotionally, but biologically.

With real insights from veterinarians, pet parents, shelters, groomers, and trainers, this episode is your guide to helping animals feel safe, calm, and cared for — one sound at a time.

What links a Möbius strip, brain folds and termite mounds? The answer is Harvard University’s L. Mahadevan, whose career has been devoted to using mathematics and physics to explore the form and function of common phenomena. Mahadevan, or Maha to his friends and colleagues, has long been fascinated by questions one wouldn’t normally ask — from the equilibrium shape of inert objects like a Möbius strip, to the complex factors that drive biological systems like morphogenesis or social insect colonies. In this episode of The Joy of Why, Mahadevan tells co-host Steven Strogatz what ...

Jordan Peterson and Sam Harris explore the breakdown of institutions in the digital age, and how difficult it’s become to identify what’s true and what’s not. Harris voices deep concern over the role independent media and social platforms play in amplifying misinformation, especially post-October 7th. They discuss the addictive, fragmenting nature of platforms like X, the erosion of trust in institutions, the dangers of AI-generated identity theft — and possible solutions. The result is a sobering analysis of epistemic collapse, digital psychopathy, and the urgent need for ...

Schon seit 1977 sind Satelliten mit dem Namen Meteosat im All. Derzeit läuft die Umstellung auf die dritte Generation. Hierfür kommen zwei verschiedene Satellitentypen zum Einsatz: "Imager" und "Sounder". Der erste Imager ist bereits im All, der erste Sounder soll im Juli 2025 folgen. Auf diesem Satelliten fliegt ein weiteres Instrument mit: Sentinel-4. Ich konnte bei OHB in Bremen konnte den ersten Sounder-Satelliten im Reinraum sehen und hatte die Gelegenheit für eine ganze Reihe von Gesprächen.

Excitement and nerves were at an all time high as my car crept down the gravel road, the sun having just slipped below the horizon. I was on the hunt, following clues to lead me to my prize. My treasure was the somewhat elusive American woodcock, and I was hoping to catch a glimpse of their infamous skydance.

Voor de bestudering van gedragsevolutie zijn we aangewezen op eigentijdse experimenten en vergelijkingen met dieren. Op basis van de neodarwinistische evolutietheorie kan aangetoond worden hoe het gedrag van mens en dier zich ontwikkelt als gevolg van de strijd om het bestaan en de overleving van de geschiktste. Door het grote voortplantingsvermogen en de beperkte draagkracht van het milieu ontstaat er concurrentie. De verschillen in eigenschappen zijn erfelijk en daardoor ontstaat er een natuurlijke selectie van "betere" eigenschappen.

All Things Bright and Beautiful is the beloved sequel to Herriot's first collection, All Creatures Great and Small, and picks up as Herriot, now newly married, journeys among the remote hillside farms and valley towns of the Yorkshire Dales, caring for their inhabitants - both two- and four-legged. Throughout, Herriot's deep compassion, humor, and love of life shine as we laugh, cry, and delight in the portraits of his many varied animal patients and their equally varied owners.

In 1973, Norma Cobb, her husband Lester, and their five children pulled up stakes in the lower 48 and headed north to Alaska to follow a pioneer dream of claiming land under the Homestead Act. The only land available lay north of Fairbanks near the Arctic Circle where grizzlies outnumbered humans 20 to one. In addition to fierce winters and predatory animals, the Alaskan frontier drew the more unsavory elements of society's fringes. From the beginning, the Cobbs found themselves pitted in a life or death feud with unscrupulous neighbors who would rob from new settlers.
