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.

Pandora's Lab takes us from opium's heyday as the pain reliever of choice to recognition of opioids as a major cause of death in the United States; from the rise of trans fats as the golden ingredient for tastier, cheaper food to the heart disease epidemic that followed; and from the cries to ban DDT for the sake of the environment to an epidemic-level rise in world malaria.

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.

His career as a naturalist and broadcaster has spanned nearly five decades and there are very few places on the globe that he has not visited. In this volume of memoirs David tells stories of the people and animals he has met and the places that he has visited. Over the last 25 years he has established himself as the world's leading Natural History programme maker with several landmark BBC series.

Sleep is one of the most important aspects of our life, health and longevity and yet it is increasingly neglected in 21st century society, with devastating consequences: every major disease in the developed world - Alzheimer's, cancer, obesity, diabetes - has very strong causal links to deficient sleep. Until very recently, science had no answer to the question of why we sleep, or what good it served, or why its absence is so damaging to our health. Compared to the other basic drives in life - eating, drinking and reproducing - the purpose of sleep remained elusive.

At the end of his career, Albert Einstein was pursuing a dream far more ambitious than the theory of relativity. He was trying to find an equation that explained all physical reality - a theory of everything. Experimental physicist and award-winning educator Dr. Don Lincoln takes you on this exciting journey in The Theory of Everything: The Quest to Explain All Reality. Suitable for the intellectually curious at all levels and assuming no background beyond basic high-school math, these 24 half-hour lectures cover recent developments at the forefront of particle physics and cosmology.

Gene Kranz was present at the creation of America's manned space program and was a key player in it for three decades. As a flight director in NASA's Mission Control, Kranz witnessed firsthand the making of history. He participated in the space program from the early days of the Mercury program to the last Apollo mission, and beyond. He endured the disastrous first years when rockets blew up and the United States seemed to fall further behind the Soviet Union in the space race.

Your nervous system is you. All the thoughts, perceptions, moods, passions, and dreams that make you an active, sentient being are the work of this amazing network of cells. For many centuries, people knew this was true. But no one was sure how it happened. Now, thanks to the exciting new field of neuroscience, we can chart the workings of the brain and the rest of the nervous system in remarkable detail to explain how neurons, synapses, neurotransmitters, and other biological processes produce all the experiences of everyday life, in every stage of life.

Sand, iron, salt, oil, copper and lithium. The struggle for these tiny, magical materials has razed empires, demolished civilizations, fed our greed and our ingenuity for thousands of years. But the story is not over. We are often told we now live in a weightless world of information but in fact we dug more stuff out of the earth in 2017 than in all of human history before 1950. And it's getting worse. To make one bar of gold, we now have to dig 5,000 tons of earth. For every tonne of fossil fuels, we extract six tonnes of other materials - from sand to stone to wood to metal.

Dish up the red meat, eggs, and whole milk! In this well-researched and captivating narrative, veteran food writer Nina Teicholz proves how everything we've been told about fat is wrong. For decades, Americans have cut back on red meat and dairy products full of "bad" saturated fats. We obediently complied with nutritional guidelines to eat "heart healthy" fats found in olive oil, fish, and nuts, and followed a Mediterranean diet heavy on fruits, vegetables, and grains. Yet the nation's health has declined. What is going on?

Neil deGrasse Tyson has a talent for guiding readers through the mysteries of outer space with stunning clarity and almost childlike enthusiasm. This collection of his essays from Natural History magazine explores a myriad of cosmic topics. Tyson introduces us to the physics of black holes by explaining what would happen to our bodies if we fell into one; he also examines the needless friction between science and religion, and notes Earth's status as "an insignificantly small speck in the cosmos".

Kids love the ocean - it’s mysterious and unknown, home to monsters of the imagination and some of the most fascinating life forms on the planet. But while many grown-ups might love being by or on the sea, how much do we actually know about the world beneath the waves? In this follow-up to A Grown-Up Guide to Dinosaurs, evolutionary biologist, Professor Ben Garrod, takes the listener on an oceanic journey from the beginning of life on Earth to the present day, discovering what the ocean actually is and why it’s so important in the evolutionary history of life.

In this groundbreaking approach to the evolution of all life, Richard Dawkins shows how the body, behaviour, and genes of every living creature can be read as a book – an archive of the worlds of its ancestors. A perfectly camouflaged desert lizard has a desiccated landscape of sand and stones ‘painted’ on its back. Its skin can be read as a description of ancient deserts in which its ancestors survived – and, before that, of the worlds of its more remote ancestors: a genetic book of the dead.

Few perspectives epitomize the sheer drama and sacrifice of combat more perfectly than those of the fighter pilots of World War II. As romanticized as any soldier in history, the World War II fighter pilot was viewed as larger than life: a dashing soul waging war amongst the clouds. In the 65-plus years since the Allied victory, stories of these pilots' heroics have never been in short supply. But what about their adversaries - the highly skilled German aviators who pushed the Allies to the very brink of defeat?
