How the Earth Works takes you on an astonishing journey through time and space. In 48 lectures, you will look at what went into making our planet - from the big bang, to the formation of the solar system, to the subsequent evolution of Earth.

In Dinosaurs Rediscovered, leading paleontologist Michael J. Benton gathers together all the latest paleontological evidence, tracing the transformation of dinosaur study from its roots in antiquated natural history to an indisputably scientific field. Among other things, the book explores how dinosaur remains are found and excavated, and especially how paleontologists read the details of dinosaurs' lives from their fossils - their colors, their growth, and even whether we will ever be able to bring them back to life.

The legendary annihilation in 1883 of the volcano-island of Krakatoa - the name has since become a byword for a cataclysmic disaster - was followed by an immense tsunami that killed nearly 40,000 people. Beyond the purely physical horrors of an event that has only very recently been properly understood, the eruption changed the world in more ways than could possibly be imagined. Dust swirled round die planet for years, causing temperatures to plummet and sunsets to turn vivid with lurid and unsettling displays of light.

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.

Gardening in Canada podcast is a podcast dedicated to the science of gardening. From cold climate gardening to indoor plants a soil scientist takes you on the journey of being a plant hobbyist

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.

Fifty thousand years ago, we were not the only species of human in the world. There were at least four others, including the Neanderthals, Homo floresiensis, Homo luzonesis and the Denisovans. At the forefront of the latter's ground-breaking discovery was Oxford Professor Tom Higham. In The World Before Us, he explains the scientific and technological advancements.

In each episode, we bring you riveting interviews with individuals who have had encounters with the elusive Sasquatch. Each one of these stories will leave you wanting more. But that's not all. We go beyond the encounters and explore the realm of Bigfoot research from a critical thinking perspective. We bring you interviews with field researchers who dedicate their lives to unraveling the mysteries surrounding Sasquatch. These dedicated individuals use hard science and rigorous methodologies to investigate the existence of this legendary creature. Through thought-provoking discussions, we aim ...

A Short History of Nearly Everything is Bill Bryson’s quest to find out everything that has happened from the Big Bang to the rise of civilization - how we got from there, being nothing at all, to here, being us. His challenge is to take subjects that normally bore the pants off most of us and see if there isn't some way to render them comprehensible to people who have never thought they could be interested in science. It's not so much about what we know, as about how we know what we know.

There are few remaining frontiers on our planet. But perhaps the wildest, and least understood, are the world's oceans: too big to police, and under no clear international authority, these immense regions of treacherous water play host to rampant criminality and exploitation.

In just the past twenty years, we have learned more about dinosaurs than we did in the previous two centuries. This book describes the extraordinary advances in palaeontology that are beginning to solve many of the mysteries surrounding these marvelous prehistoric creatures, from their ways of communicating to their mating habits, the colour of their skin, their migration patterns and extinction. How did dinosaurs rear their young? What did they eat? What did T. rex actually do with those tiny arms?

World renowned scientist, Dr. Gerald Pollack, takes us on a fantastic voyage through water, showing us a hidden universe teeming with physical activity - providing simple explanations for everyday phenomena, which you have inevitably seen but not really understood. Have you ever wondered how do clouds made up of dense water droplets manage to float in the sky? Why don't your joints squeak as they rub together? Why do you sink in dry sand, but not in wet sand? Pollack uses a recent and fundamental scientific finding - EZ water - to help explain these and many other head-scratchers.

As one of the most celebrated cave divers in the world, Jill Heinerth has seen the planet in a way almost no one has. In a workday, she might swim below your home, through conduits in volcanoes or cracks in the world's largest iceberg. She's an explorer, a scientist's eyes and hands underwater - discovering new species and examining our finite freshwater reserves - and a filmmaker documenting the wonders of underwater life. Often the lone woman in a male-dominated domain, she tests the limits of human endurance at every tight turn, risking her life with each mission.

CBC Radio's Quirks and Quarks covers the quirks of the expanding universe to the quarks within a single atom... and everything in between.

Adored by children and adults alike, tyrannosaurus is the most famous dinosaur in the world, one that pops up again and again in pop culture, often battling other beasts such as King Kong, triceratops, or velociraptors in Jurassic Park. But despite the hype, tyrannosaurus and the other tyrannosaurs are fascinating animals in their own right and are among the best-studied of all dinosaurs.

Cosmos is one of the bestselling science books of all time. In clear-eyed prose, Sagan reveals a jewel-like blue world inhabited by a life form that is just beginning to discover its own identity and to venture into the vast ocean of space.

For months in early 1980, scientists, journalists, and ordinary people listened anxiously to rumblings in the long quiescent volcano Mount St. Helens. Still, when a massive explosion took the top off the mountain, no one was prepared. Fifty-seven people died, including newlywed logger John Killian (for years afterward, his father searched for him in the ash), scientist Dave Johnston, and celebrated local curmudgeon Harry Truman. The lives of many others were forever changed.

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.

Join David and Will as they explore the paleontologists’ perspective on various topics in life and earth history. Each episode features a main discussion on a topic requested by the listeners, presented as a lighthearted and educational conversation about fossils, evolution, deep time, and more. Before the main discussion, each episode also includes a news segment, covering recent research related to paleontology and evolution.

What if Atlantis wasn't a myth but an early precursor to a new age of great flooding? Across the globe, scientists and civilians alike are noticing rapidly rising sea levels and higher and higher tides pushing more water directly into the places we live, from our most vibrant, historic cities to our last remaining traditional coastal villages. With each crack in the great ice sheets of the Arctic and Antarctica and each tick upward of Earth's thermometer, we are moving closer to the brink of broad disaster.
