In this groundbreaking work, evolutionary biologist Jared Diamond stunningly dismantles racially based theories of human history by revealing the environmental factors actually responsible for history's broadest patterns. It is a story that spans 13,000 years of human history, beginning when Stone Age hunter-gatherers constituted the entire human population. Guns, Germs, and Steel is a world history that really is a history of all the world's peoples, a unified narrative of human life.

People who have never been depressed have no idea what it's like. And people who have know all too well how tough depression can be to live with. Dr. Faith explains the brain science behind depression, complete with Zuul references, and talks you through the different options out there for getting better. Yes there are things you can do to feel good again (including drugs, but avoiding a spiraling successions of drug cocktails).

The deep-learning revolution has brought us driverless cars, the greatly improved Google Translate, fluent conversations with Siri and Alexa, and enormous profits from automated trading on the New York Stock Exchange. Deep-learning networks can play poker better than professional poker players and defeat a world champion at Go. In this book, Terry Sejnowski explains how deep learning went from being an arcane academic field to a disruptive technology in the information economy.

In 1973, Norma Cobb, her husband Lester, and their five children pulled up stakes in the lower 48 and headed north to Alaska to follow a pioneer dream of claiming land under the Homestead Act. The only land available lay north of Fairbanks near the Arctic Circle where grizzlies outnumbered humans 20 to one. In addition to fierce winters and predatory animals, the Alaskan frontier drew the more unsavory elements of society's fringes. From the beginning, the Cobbs found themselves pitted in a life or death feud with unscrupulous neighbors who would rob from new settlers.

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.

Living at the limits of our ordinary perception, mosses are a common but largely unnoticed element of the natural world. Gathering Moss is a beautifully written mix of science and personal reflection that invites listeners to explore and learn from the elegantly simple lives of mosses.

In this monumental history, Vaclav Smil provides a comprehensive account of how energy has shaped society, from pre-agricultural foraging societies through today's fossil fuel-driven civilization and offers listeners a magisterial overview of humanity's energy eras.

Written for those with no physics background, Paul Levy's latest book, The Quantum Revelation: A Radical Synthesis of Science and Spirituality, is for those who have heard that quantum physics is a fascinating subject but don't quite understand how or why.

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.

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.

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.

Bob Lazar was a brilliant young physicist that found himself employed at a top-secret facility in the middle of the desert outside Las Vegas. Under the watchful eye of the government elite, he is tasked with understanding an exotic propulsion system being used by an advanced aerospace vehicle he is told came from outer space. The stressful work and long, odd hours start to wear on Bob and he becomes concerned for his safety. He tells his wife and a couple close friends about what he's doing in the desert, and his employers find out and are furious.

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 the Earth in 25 Rocks tells the fascinating stories behind the discoveries that shook the foundations of geology. In 25 chapters, Donald R. Prothero recounts the scientific detective work that shaped our understanding of geology, from the unearthing of exemplary specimens to tectonic shifts in how we view the inner workings of our planet.

In this fascinating and thought-provoking book, author Nick Lane brings together the latest research findings in the exciting field of mitochondria research to reveal how our growing understanding of mitochondria is shedding light on how complex life evolved, why sex arose (why don't we just bud?), and why we age and die. This understanding is of fundamental importance, both in understanding how we and all other complex life came to be, but also in order to be able to control our own illnesses, and delay our degeneration and death.

Since his early days of plant restoration, amateur plant scientist Matt Candeias has been enchanted with flora and the greater environmental ecology of the planet. Now, he looks at the study of plants through the lens of his ever-growing houseplant collection.

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 hunt for the Higgs particle has involved the biggest, most expensive experiment ever. So exactly what is this particle? Why does it matter so much? What does it tell us about the universe? Was finding it really worth all the effort? The short answer is yes. The Higgs field is proposed as the way in which particles gain mass - a fundamental property of matter. It's the strongest indicator yet that the Standard Model of physics really does reflect the basic building blocks of our universe. Little wonder the hunt and discovery of this new particle produced such intense media interest.

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.

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.
