Nowhere on our planet is devoid of life. Plants and animals thrive or survive within every extreme of climate and habitat that it offers. Single species, and often whole communities, adapt to make the most of ice cap and tundra, forest and plain, desert, ocean and volcano. These adaptations can be truly extraordinary. In Living Planet, David Attenborough’s searching eye, unfailing curiosity and infectious enthusiasm explain and illuminate the intricate lives of the these colonies.

According to the UN Convention to Combat Desertification (UNCCD), each year, an estimated 24 billion tons of fertile soil are lost due to erosion. That’s a whopping 3.4 tons lost every year for each person on the planet.

Where do we come from? How did our ancestors settle this planet? How did the great historic civilizations of the world develop? How does a past so shadowy that it has to be painstakingly reconstructed from fragmentary, largely unwritten records nonetheless make us who and what we are?

These 36 lectures bring you the answers that the latest scientific and archaeological research and theorizing suggest about human origins, how populations developed, and the ways in which civilizations spread throughout the globe.

What is life? In this penetrating and wide-ranging book, world-renowned physicist and science communicator Paul Davies searches for answers in a field so new and fast-moving that it lacks a name; it is a domain where biology, computing, logic, chemistry, quantum physics, and nanotechnology intersect.

Deep is a voyage from the ocean's surface to its darkest trenches, the most mysterious places on Earth. Fascinated by the sport of freediving - in which competitors descend to great depths on a single breath - James Nestor embeds with a gang of oceangoing extreme athletes and renegade researchers. He finds whales that communicate with other whales hundreds of miles away, sharks that swim in unerringly straight lines through pitch-black waters, and other strange phenomena.

There is nothing more essential to our health and well-being than breathing. Yet, as a species, humans have lost the ability to breathe correctly, with grave consequences. Journalist James Nestor travels the world to figure out what went wrong and how to fix it. The answers aren’t found in pulmonology labs, as we might expect, but in the muddy digs of ancient burial sites, secret Soviet facilities, New Jersey choir schools, and the smoggy streets of São Paulo. Nestor tracks down men and women exploring the hidden science behind ancient breathing practices.

Acclaimed scientist Hope Jahren has built three laboratories in which she's studied trees, flowers, seeds, and soil. Her first book might have been a revelatory treatise on plant life. Lab Girl is that, but it is also so much more. Because in it, Jahren also shares with us her inspiring life story, in prose that takes your breath away.

Lobster has been a phenomenal success story, with a commercial fishery that has generated enormous wealth and fuelled appetites for one of the world’s most recognizable luxury foods. The great lobster boom that began in the 1990s has also led to violent fights over who has the right to catch this valuable seafood, including many Indigenous people in Canada, who until recently have been excluded from this industry. Now overfishing, trade wars, and climate change are threatening the future of this fishery in deeply troubling ways.

The Real Anthony Fauci details how Fauci, Gates, and their cohorts use their control of media outlets, scientific journals, key government and quasi-governmental agencies, global intelligence agencies, and influential scientists and physicians to flood the public with fearful propaganda about COVID-19 virulence and pathogenesis, and to muzzle debate and ruthlessly censor dissent.

Every day we draw in two thousand gallons of air—and thousands of living things. From the ground to the stratosphere, the air teems with invisible life. This last great biological frontier remains so mysterious that it took over two years for scientists to finally agree that the COVID pandemic was caused by an airborne virus. In Air-Borne, award-winning New York Times columnist and author Carl Zimmer leads us on an odyssey through the living atmosphere and through the history of its discovery.

If you've ever wondered why you seem to get trapped in an endless cycle of obsessive, compulsive thoughts, you don't have to wonder anymore. Grounded in cutting-edge neuroscience and evidence-based cognitive behavioral therapy (CBT), Rewire Your OCD Brain will show you how and why your brain gets stuck in a loop of obsessive thinking, uncertainty, and worry; and offers the tools you need to short-circuit this response and get your symptoms under control-for good.

The past is past, but it does leave clues, and Thomas Halliday has used cutting-edge science to decipher them more completely than ever before. In Otherlands, Halliday makes sixteen fossil sites burst to life.

Food is one of life's great joys. So why has eating become such a source of anxiety and confusion? Bee Wilson shows that in two generations the world has undergone a massive shift from traditional, limited diets to more globalized ways of eating, from bubble tea to quinoa, from Soylent to meal kits. Paradoxically, our diets are getting healthier and less healthy at the same time. For some, there has never been a happier food era than today: a time of unusual herbs, farmers' markets, and internet recipe swaps.

Mary Siisip Geniusz has spent more than thirty years working with, living with, and using the Anishinaabe teachings, recipes, and botanical information, she shares in Plants Have So Much to Give Us, All We Have to Do Is Ask. Geniusz gained much of the knowledge she writes about from her years as an oshkaabewis, a traditionally trained apprentice, and as friend to the late Keewaydinoquay, an Anishinaabe medicine woman from the Leelanau Peninsula in Michigan and a scholar, teacher, and practitioner in the field of native ethnobotany.

Plants play a critical role in how we experience our environment. They create calming green spaces, provide oxygen for us to breathe, and nourish our senses. In The Nature of Plants, ecologist and nursery owner Craig Huegel demystifies the complex lives of plants and provides listeners with an extensive tour into their workings.

When we think of fungi, we likely think of mushrooms. But mushrooms are only fruiting bodies, analogous to apples on a tree. Most fungi live out of sight, yet make up a massively diverse kingdom of organisms that supports and sustains nearly all living systems. Fungi provide a key to understanding the planet on which we live, and the ways we think, feel, and behave.

EMS 20/20 is podcast hosted by two experienced Paramedics. Spencer Oliver and Christopher Pfingsten discuss real calls run by real responders and pull out the lessons you won't find in a text book. This podcast is aimed at Paramedic students, seasoned Paramedics looking to refresh, or any one interested in a deeper dive into pre-hospital health care.

We humans are the inheritors of a dynasty that has reigned over the planet for nearly 66 million years, through fiery cataclysm and ice ages: the mammals. Our lineage includes saber-toothed tigers, woolly mammoths, armadillos the size of a car, cave bears three times the weight of a grizzly, clever scurriers that outlasted Tyrannosaurus rex, and even other types of humans, like Neanderthals.

In Your Brain Is a Time Machine, brain researcher and best-selling author Dean Buonomano draws on evolutionary biology, physics, and philosophy to present his influential theory of how we tell and perceive time. The human brain, he argues, is a complex system that not only tells time but creates it; it constructs our sense of chronological flow and enables "mental time travel" - simulations of future and past events.

Conventional science has long held the position that 'the mind' is merely an illusion, a side effect of electrochemical activity in the physical brain. Now in paperback, Dr Jeffrey Schwartz and Sharon Begley's groundbreaking work, The Mind and the Brain, argues exactly the opposite: that the mind has a life of its own. Dr Schwartz, a leading researcher in brain dysfunctions, and Wall Street Journal science columnist Sharon Begley demonstrate that the human mind is an independent entity that can shape and control the functioning of the physical brain.
