Although we usually think of technology as something unique to modern times, our ancestors began to create the first technologies millions of years ago in the form of prehistoric tools and weapons. Over time, eight key technologies gradually freed us from the limitations of our animal origins.

We live at the bottom of an ocean of air - 5,200 million million tons, to be exact. It sounds like a lot, but Earth’s atmosphere is smeared onto its surface in an alarmingly thin layer - 99 percent contained within 18 miles. Yet, within this fragile margin lies a magnificent realm - at once gorgeous, terrifying, capricious, and elusive. With his keen eye for identifying and uniting seemingly unrelated events, Chris Dewdney reveals to us the invisible rivers in the sky that affect how our weather works and the structure of clouds and storms and seasons, the rollercoaster of climate.

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.

Why do people believe bunk? And what causes them to embrace such pseudoscientific beliefs and practices? Noted skeptic Massimo Pigliucci sets out to separate the fact from the fantasy in this entertaining exploration of the nature of science, the borderlands of fringe science, and - borrowing a famous phrase from philosopher Jeremy Bentham - the nonsense on stilts.

Over the past 20 years, paleontologists have made tremendous fossil discoveries, including fossils that mark the growth of whales, manatees, and seals from land mammals and the origins of elephants, horses, and rhinos. Today there exists an amazing diversity of fossil humans, suggesting we walked upright long before we acquired large brains, and new evidence from molecules that enable scientists to decipher the tree of life as never before.

La situation n'est pas désespérée. La solution est en nous. Ça y est, nous avons dépassé le stade critique. Le dernier rapport du GIEC atteste que la vie sur terre deviendra à terme insoutenable. La cause : le réchauffement climatique que nous avons-nous-mêmes enclenché. Nous savons que nous sommes en perdition et nous ne réagissons pas. Pourquoi ? Sans qu'on le sache, se joue depuis des millénaires dans notre cerveau une terrible bataille. D'un côté il y a le striatum, petite structure nerveuse qui génère du plaisir. De l'autre il y a le cortex préfrontal, organe destiné à contrôler nos pulsions.

An icon of the environmental movement outlines a provocative approach for reclaiming our planet. According to Stewart Brand, a lifelong environmentalist who sees everything in terms of solvable design problems, three profound transformations are under way on Earth right now. Climate change is real and is pushing us toward managing the planet as a whole. Urbanization - half the world's population now lives in cities, and 80 percent will by midcentury - is altering humanity's land impact and wealth.

The history of the Great Warming of a half millennium ago suggests that we may yet be underestimating the power of climate change to disrupt our lives todayand our vulnerability to drought, writes Fagan, is the silent elephant in the room.

A preeminent geneticist hunts the Neanderthal genome to answer the biggest question of them all: what does it mean to be human? What can we learn from the genes of our closest evolutionary relatives? Neanderthal Man tells the story of geneticist Svante Pbo’s mission to answer that question, beginning with the study of DNA in Egyptian mummies in the early 1980s and culminating in his sequencing of the Neanderthal genome in 2009.

When leading Princeton physicist Paul Steinhardt began working in the 1980s, scientists thought they knew all the conceivable forms of matter. The Second Kind of Impossible is the story of Steinhardt’s 35-year-long quest to challenge conventional wisdom. It begins with a curious geometric pattern that inspires two theoretical physicists to propose a radically new type of matter - one that raises the possibility of new materials with never-before-seen properties but that violates laws set in stone for centuries.

The thrilling story of the charismatic explorer who Simon Bolivar called "the true discoverer of South America" and the daring expedition that altered the course of science. From 1799 to 1804 German naturalist and adventurer Alexander von Humboldt conducted the first extensive scientific exploration of Latin America.

The science is overwhelming; the facts are in. The planet is heating up at an alarming rate and the results are everywhere to be seen. Yet, as time runs out, climate progress is blocked by the men who are profiting from the burning of the planet: energy moguls like the Koch brothers and Exxon Mobil CEO Rex Tillerson. Powerful politicians like Senators Mitch McConnell and Jim Inhofe, who receive massive contributions from the oil and coal industries. Most of these men are too intelligent to truly believe that climate change is not a growing crisis.

In Tibet, geologist David R. Montgomery heard a local story about a great flood that bore a striking similarity to Noah’s Flood. Intrigued, Montgomery began investigating theworld’s flood stories and - drawing from historic works by theologians, natural philosophers, and scientists - discovered the counterintuitive role Noah’s Flood played in the development of both geology and creationism.

In its 2001 report on global climate, the Intergovernmental Panel on Climate Change of the United Nations prominently featured the "Hockey Stick", a chart showing global temperature data over the past 1,000 years. The Hockey Stick demonstrated that temperature had risen with the increase in industrialization and use of fossil fuels. The inescapable conclusion was that worldwide human activity since the industrial age had raised CO2 levels, trapping greenhouse gases in the atmosphere and warming the planet.

The earth has died many times, and it always comes back looking different. In an exhilarating, surprising exploration of our planet, Craig Childs takes listeners on a firsthand journey through apocalypse, touching the truth behind the speculation. Apocalyptic Planet is a combination of science and adventure that reveals the ways in which our world is constantly moving toward its end and how we can change our place within the cycles and episodes that rule it.

In Born in Africa, Martin Meredith follows the trail of discoveries about human origins made by scientists over the last hundred years, recounting their intense rivalry, personal feuds, and fierce controversies, as well as their feats of skill and endurance. The results have been momentous. Scientists have identified more than 20 species of extinct humans. They have firmly established Africa as the birthplace not only of humankind but also of modern humans.

We have long fantasized about finding life on planets other than our own. Yet even as we become aware of the vast expanses beyond our solar system, it remains clear that Earth is exceptional. The question is: Why? In Lucky Planet, astrobiologist David Waltham argues that Earth’s climate stability is what makes it uniquely able to support life, and it is nothing short of luck that made such conditions possible. The four-billion-year stretch of good weather that our planet has experienced is statistically so unlikely that chances are slim that we will ever encounter intelligent extraterrestrial others.

The idea of a missing link between humanity and our animal ancestors predates evolution and popular science and actually has religious roots in the deist concept of the Great Chain of Being. Yet, the metaphor has lodged itself in the contemporary imagination, and new fossil discoveries are often hailed in headlines as revealing the elusive transitional step, the moment when we stopped being "animal" and started being "human". In The Accidental Species, Henry Gee, longtime paleontology editor at Nature, takes aim at this misleading notion.

Wagner and Martin Weitzman explore in lively, clear terms the likely repercussions of a hotter planet, drawing on and expanding from work previously unavailable to general audiences. They show that the longer we wait to act, the more likely an extreme event will happen. A city might go underwater.

Some see dust as dull stuff, useless at best, and sneeze-inducing at worst. But in the hands of writer Hannah Holmes, dust becomes a dazzling and mysterious force. As Holmes says, dust is a messenger, and air is its medium. And by the end of this fascinating journey through The Secret Life of Dust, we cannot help but agree.
