Fennec foxes’ ears can be up to half as long as their bodies. They use them to track movement across the Sahara Desert, including under the sand. In this episode, we follow a fox as he meanders home to his family through the sand dunes as they slowly shift with the wind.

Humpback whales are among the most intelligent animals on Earth. Some scientists believe they might even surpass humans in self-awareness, empathy, and communication skills. In this episode, we swim with a whale as he teams up with other humpbacks to use bubbles to catch fish, rescues a sea lion, and puts his own spin on melodies sung by whales across the Pacific Ocean. This is the world in its natural state, defined by seasons, routines, and cycles. By the time this whale is ready to close one eye and go to sleep, you will be too.

Dung beetles might sound dirty, but the ancient Egyptians believed their god took the form of a dung beetle to roll the morning sun across the sky every day. In this episode, we roll with dung beetles around the world as they push their precious dung—often in balls many times larger than they are—over Florida pastures, Armenian highlands, and the vast South African savanna.

Sloths are the slowest mammals on earth. They can hardly see. They live in rainforests among jaguars, pumas, and countless other predators. Yet they survive. And they do it by being so incredibly slow, and living a life covered in algae. In this episode, we hang with a sloth in the jungle of Costa Rica as he spends a month digesting one single leaf, and we see the symbiosis and collaboration that surrounds him.

Susan S. Scott is an experienced psychotherapist who, due to a back injury, was forced to abandon her therapist's couch and walk for therapy. Through her extended strolls through nature, she discovered the ingenious ability of trees to grow around obstacles and, in essence, heal themselves. The result of Dr. Scott's musings is Healing with Nature. This collection of stories and photos describes a different aspect of the healing process.

Platypuses are mammals unlike any other on earth. They lay eggs, ooze milk through their skin, and can sense electricity. In this episode, we travel with a platypus as he moves through his nightly routine on the island of Tasmania. He uses electroreceptors to hunt underwater and does a synchronized swimming courtship ritual with his mate, who then digs a burrow 40 feet deep into the riverbank to nest.

Brown bears lead deeply cyclical lives. They need to gain sometimes hundreds of pounds during the warmer months to prepare for winter hibernation, a lifestyle that brings them into frequent contact with many other species’ cycles. In this episode, we meander through the Alaska peninsula with a bear and her cubs as she teaches them to hunt salmon at the falls, dig for clams along the coastal mudflats, and use the regional rubbing tree.

Dogs are a familiar and comforting part of many of our lives. In this episode, we take a walk with a pet xoloitzcuintli, or Mexican hairless dog, as he greets his blocks by smell. Along the way, we learn the backstory of squirrels in U.S. cities and observe the very smart and clean neighborhood raccoon.

Elephants are the largest land animals in the world. They are also intensely social and have advanced long-term memories. In this episode, a parade of Asian elephants makes its way through the Sri Lankan forest to a lake for drinks and mud baths, stopping periodically for group naps. The female leading the parade uses infrasonic rumbles—inaudible to humans, but traveling as far as two miles along the surface of the Earth as seismic waves—to invite friends and family around the forest to join her at the reservoir.

Crows have long been the subject of folklore, likely because they’re strikingly similar to humans, leading lives rich in personality, intelligence, and relationships. In this episode, we fly the streets of Seattle with a crow as she grooms her mate, delivers what appears to be a gift, and finally commutes miles away from her territory to gather and chat with thousands of other crows before it’s time to roost for the night.

The sun sinks over the Rio Grande, the mountains around it glow orange, and the world slows down. The Mexican free-tailed bats inside the Jornada Cave are just starting to stretch and murmur. In this episode, we visit the nursery where all the baby bats stay together, and we accompany a new mother as she journeys into the sky with the rest of her crew for a night of hunting bugs via echolocation.

In the tradition of Jared Diamond and Jacques Barzun, prize-winning historian Anthony Pagden presents a sweeping history of the long struggle between East and West, from the Greeks to the present day.

The relationship between East and West has always been one of turmoil. In this historical tour de force, a renowned historian leads us from the world of classical antiquity, through the Dark Ages, to the Crusades, Europe's resurgence, and the dominance of the Ottoman Empire, which almost shattered Europe entirely. Pagden travels from Napoleon in Egypt to Europe's carving up of the finally moribund Ottomans - creating the modern Middle East along the way - and on to the present struggles in Iraq.

Nur zwei große Lebensräume unserer Erde sind scheinbar über lange Zeiträume hinweg gleich geblieben: der Dschungel und das Meer. Doch selbst die Landmassen, auf denen der Urwald liegt, haben sich aufgrund der Kontinentalverschiebungen verändert, und die Aufspal­tung und Verschmelzung der Kontinente hatten Auswirkungen auf die Ausdehnung der warmen, flachen Küstenmeere.

Der Wald tut uns gut, das spüren wir intuitiv. Doch was bisher mehr ein Gefühl war, belegt jetzt die Wissenschaft. Sie erforscht das heilende Band zwischen Mensch und Natur, das einen viel stärkeren Effekt auf uns hat, als wir bisher dachten. So kommunizieren Pflanzen mit unserem Immunsystem, ohne dass es uns bewusst wird, und stärken dabei unsere Widerstandskräfte. Bäume sondern unsichtbare Substanzen ab, die gegen Krebs wirken.

Somos um país urbano: 84% da população brasileira concentra-se em cidades e ao menos metade vive em municípios com mais de 100 mil habitantes. Mas a vida urbana não traz apenas novas oportunidades. Ela propicia doenças provocadas por falta de saneamento, picadas de mosquitos, poluição, violência, ritmo frenético... E tudo isso não ocorre mais apenas nas grandes cidades, mas também nas médias e mesmo pequenas, quase sempre negligenciadas pelo poder público e pelos próprios cidadãos.
