Throughout his research into memory theory, Nelson Dellis found existing memory improvement guides to be wanting - overcomplicated, dry, and stodgy. So he decided to create a book that is approachable and fun, centered on what people actually need to remember. In Remember It!, Dellis teaches us how to make the most of our memory, using his competition-winning techniques.

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.

The story of our world and the different living things that have populated it is an amazing epic with millions of species, exotic settings, planet-wide cataclysms, and surprising plot twists. These 36 lectures tell the all-embracing story of life on Earth - its origins, extinctions, and evolutions - in a manner that assumes no background in science. At half an hour per lecture, you’ll cover the entire 4.54-billion-year history of Earth in 18 hours, averaging 70,000 years per second!

The fifth volume of memoirs from the author who inspired the BBC series All Creatures Great and Small. During his decades spent as a country vet in Yorkshire, James Herriot has seen huge advances in medical science, technological leaps, and a world irrevocably changed by war. Yet some things have always stayed the same - gruff farmers, hypochondriac pet owners, and animals that never do quite what you expect them to.

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.

For a thousand generations, human beings viewed themselves as part of the wider community of nature, and they carried on active relationships not only with other people but with other animals, plants, and natural objects (including mountains, rivers, winds, and weather patterns) that we have only lately come to think of as "inanimate". How, then, did humans come to sever their ancient reciprocity with the natural world?

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.

As a botanist and professor of plant ecology, Robin Wall Kimmerer has spent a career learning how to ask questions of nature using the tools of science. As a Potawatomi woman, she learned from elders, family, and history that the Potawatomi, as well as a majority of other cultures indigenous to this land, consider plants and animals to be our oldest teachers.

Whether you live in a mountain cabin or a city loft, plant spirits present themselves to us everywhere. Since its first edition in 1995, Plant Spirit Medicine has passed among countless audiences drawn to indigenous spirituality and all things alive and green. In this updated edition, Eliot Cowan invites us to discover the healing power of plants - not merely their physical medicinal properties, but the deeper wisdom and gifts that they offer.

One of the most complicated and advanced computers on Earth can't be purchased in any store. This astonishing device, responsible for storing and retrieving vast quantities of information that can be accessed at a moment's notice, is the human brain. How does such a dynamic and powerful machine make memories, learn a language, and remember how to drive a car? What habits can we adopt in order to learn more effectively throughout our lives? The answers to these questions are merely the tip of the iceberg in The Learning Brain.

Sleep is one of the most important but least understood aspects of our life, wellness, and longevity. Until very recently, science had no answer to the question of why we sleep, or what good it served, or why we suffer such devastating health consequences when we don't sleep. Compared to the other basic drives in life - eating, drinking, and reproducing - the purpose of sleep remained elusive.

The theory of evolution unites the past, present, and future of living things. It puts humanity's place in the universe into necessary perspective. Despite a history of controversy, the evidence for evolution continues to accumulate as a result of many separate strands of incredible scientific sleuthing. In The Story of Evolution in 25 Discoveries, Donald R. Prothero explores the most fascinating breakthroughs in piecing together the evidence for evolution.

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 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.

Levitin looks at the science behind what we all can learn from those who age joyously, as well as how to adapt our culture to take full advantage of older people's wisdom and experience. Throughout his exploration of what aging really means, using research from developmental neuroscience and the psychology of individual differences, Levitin reveals resilience strategies and practical, cognitive enhancing tricks everyone should do as they age.

Chemistry and Our Universe: How It All Works is your in-depth introduction to this vital field, taught through 60 engaging half-hour lectures that are suitable for any background or none at all. Covering a year’s worth of introductory general chemistry at the college level, plus intriguing topics that are rarely discussed in the classroom, this amazingly comprehensive course requires nothing more advanced than high-school math. Your guide is Professor Ron B. Davis, Jr., a research chemist and award-winning teacher at Georgetown University.

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.

This course chronicles the history of Earth and life on Earth from the point of view of the minerals that made it all happen. A major theme is how minerals and life coevolved, leading to the unprecedented mineral diversity on our world compared to the other planets in the solar system. Professor Hazen tells this epic story in 48 action-packed lectures that take you from the big bang to the formation of the solar system to the major milestones that marked the evolution of Earth and life.

Evolutionary theory has long established that humans are animals: Modern Homo sapiens are primates who share an ancestor with monkeys and other great apes. Our genome is 98 percent identical to a chimpanzee's. And yet we think of ourselves as exceptional. Are we? In this original and entertaining tour of life on Earth, Adam Rutherford explores the profound paradox of the "human animal".

Sadhguru, founder of Isha Foundation is a yogi, mystic and spiritual master with a difference. An arresting blend of profundity and pragmatism, his life and work serve as a reminder that inner sciences are not esoteric philosophies from an outdated past, but a contemporary science vitally relevant to our times.
