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.

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.

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.

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.

The story of viruses and humanity is a story of fear and ignorance, of grief and heartbreak, and of great bravery and sacrifice. Michael Oldstone tells all these stories as he illuminates the history of the devastating diseases that have tormented humanity, focusing mostly on the most famous viruses. For this revised edition, Oldstone includes discussions of new viruses like SARS, bird flu, virally caused cancers, chronic wasting disease, and West Nile. Viruses, Plagues, and History paints a sweeping portrait of humanity's long-standing conflict with our unseen viral enemies.

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.

Lucid Dreaming - conscious awareness during the dream state - is an exhilarating experience. Because the world you are experiencing is one of your own creation, you can do the impossible and consciously influence the outcome of your dreams.

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.

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.

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.

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.

Life these days can feel like an endless, exhausting to-do list with far too many to-dos and not nearly enough time to complete them. Self-help gurus will tell you to time block, to wake up at five am, to try the Pomodoro method, and get rid of everything in your life that doesn't spark joy—but the reality is you can't bullet journal your way out of exhaustion. Instead, science journalist Amy Arthur argues for a radical new approach: we must learn to manage not our time, but our energy.

This pioneering account sets out to understand the structure of the human brain - the place where mind meets matter. Until recently, the left hemisphere of our brain has been seen as the "rational" side, the superior partner to the right. But is this distinction true? Drawing on a vast body of experimental research, Iain McGilchrist argues while our left brain makes for a wonderful servant, it is a very poor master.

The US spends more than any other nation, nearly four trillion dollars, on health care. Yet, for all that expense, the US is not ranked number one - not even close. In Which Country Has the World's Best Healthcare? Ezekiel Emanuel profiles 11 of the world's health-care systems in pursuit of the best or at least where excellence can be found.

In The WEIRDest People in the World, Joseph Henrich draws on cutting-edge research in anthropology, psychology, economics, and evolutionary biology to explore these questions and more. He illuminates the origins and evolution of family structures, marriage, and religion, and the profound impact these cultural transformations had on human psychology. Mapping these shifts through ancient history and late antiquity, Henrich reveals that the most fundamental institutions of kinship and marriage changed dramatically under pressure from the Roman Catholic Church.

If you have a daughter, it would be surprising if she doesn't struggle with anxiety and worry - either in short episodes or for longer periods. For a variety of reasons, childhood anxiety rates are soaring, especially among girls. Today's parents need to know what contributes to anxiety and worry and how they can empower their daughters to overcome troubling emotions. With your help, she will find the anchoring truth of God's strong, safe love for her and the confidence she needs to thrive.

The Emperor of All Maladies reveals the many faces of an iconic, shape-shifting disease that is the defining plague of our generation. The story of cancer is a story of human ingenuity, resilience, and perseverance but also of hubris, arrogance, paternalism, and misperception, all leveraged against a disease that, just three decades ago, was thought to be easily vanquished in an all-out "war against cancer".

In 2014, after losing several friends and relatives to cancer, an unassuming insurance underwriter in Hoosick Falls, New York, began to suspect that the local water supply was polluted. When he tested his tap water, he discovered dangerous levels of forever chemicals. This set off a chain of events that led to 100 million Americans learning their drinking water was tainted. Although the discovery came as a shock to most, the U.S. government and the manufacturers of these toxic chemicals had known about their hazards for decades.

Statistics show that 50 percent of what determines divorce is genetic temperament. And, if you are one of the 20 percent of people who are born highly sensitive, the risk of an unhappy relationship is especially high. Your finely tuned nervous system, which picks up on subtleties and reflects deeply, would be a romantic asset if both you and your partner understood you better. But without that understanding, your sensitivity is likely to be making your close relationships painful and complicated.
