Fifty thousand years ago - merely a blip in evolutionary time - our Homo sapiens ancestors were competing for existence with several other human species, just as their precursors had done for millions of years. Yet something about our species distinguished it from the pack, and ultimately led to its survival while the rest became extinct. Just what was it that allowed Homo sapiens to become masters of the planet? Ian Tattersall, curator emeritus at the American Museum of Natural History, takes us deep into the fossil record to uncover what made humans so special.

Adam Savage is a maker. From Chewbacca’s bandolier to a 1,000-shot Nerf gun, he has built thousands of spectacular projects as a special-effects artist and the cohost of MythBusters.

In this practical and passionate guide, Adam weaves together vivid personal stories, original sketches and photographs from some of his most memorable projects, and interviews with many of his iconic and visionary friends.

Since its publication in 1977, The Unsettling of America has been recognized as a classic of American letters. In it, Wendell Berry argues that good farming is a cultural and spiritual discipline. Today’s agribusiness, however, takes farming out of its cultural context and away from families. As a result, we as a nation are more estranged from the land - from the intimate knowledge, love, and care of it.

We tell the stories and history of haunted places, ghost encounters, cryptid encounters, the paranormal, preternatural, and every oddity imaginable.

In 1994 Professor Bryan Sykes, a leading world authority on DNA and human evolution, was called in to examine the frozen remains of a man trapped in glacial ice in northern Italy. News of both the Ice Man's discovery and his age, which was put at over 5,000 years, fascinated scientists and newspapers throughout the world. But what made Sykes's story particularly revelatory was his successful identification of a genetic descendant of the Ice Man, a woman living in Great Britain today. How was Sykes able to locate a living relative?

In 1978, the first group of space shuttle astronauts was introduced to the world - 29 men and six women who would carry NASA through the most tumultuous years of the space shuttle program. Among them was USAF Colonel Mike Mullane, who, in his memoir Riding Rockets, strips the heroic veneer from the astronaut corps and paints them as they are - human.

Paul Scharre, a Pentagon defense expert and former U.S. Army Ranger, explores what it would mean to give machines authority over the ultimate decision of life or death. Scharre's far-ranging investigation examines the emergence of autonomous weapons, the movement to ban them, and the legal and ethical issues surrounding their use. Through interviews with defense experts, ethicists, psychologists, and activists, Scharre surveys what challenges might face "centaur warfighters" on future battlefields. 

Florida's Space Coast tells the compelling story of America's half century in space exploration from the successful launch of the first two-stage rocket in 1950 through the space shuttle missions of 2000. Told from the unique viewpoint of the people who built the Spaceport, this book shows how the space program transformed the east central Florida coast from a traditional citrus production and tourist area to one of the most influential high-tech centers in the nation.

Florida has long beckoned retirees seeking to spend their golden years in the sun, but, for many, the American dream of owning a home there was financially impossible. That changed in the 1950s, when the so-called "installment land sales industry" appeared out of nowhere to hawk billions of dollars of Florida residential property, sight unseen, to retiring northerners. For only $10 down and $10 a month, working-class pensioners could buy a piece of the Florida dream: a graded homesite that would be waiting for them in a planned community when they were ready to build.

Earth evolves. From first atom to molecule, mineral to magma, granite crust to single cell to verdant living landscape, ours is a planet constantly in flux. In this radical new approach to Earth’s biography, senior Carnegie Institution researcher and national best-selling author Robert M. Hazen reveals how the co-evolution of the geosphere and biosphere - of rocks and living matter - has shaped our planet into the only one of its kind in the Solar System, if not the entire cosmos.

Il cervello è l’organo in grado di invecchiare meno di tutti gli altri. Meno del fegato, della pelle o del cuore. Prendercene cura è la nostra unica opportunità di estendere la giovinezza, di assaporare a lungo la vita e di salvaguardare allo stesso tempo la salute del corpo. Come racconta in questo libro Michela Matteoli, tra i neuroscienziati italiani più riconosciuti a livello internazionale, il cervello ha un punto di forza: la plasticità, cioè la proprietà di modificare se stesso e di autoripararsi.

In Dumb Luck and the Kindness of Strangers, Gierach looks back to the long-ago day when he bought his first resident fishing license in Colorado, where the fishing season never ends, and just knew he was in the right place. And he succinctly sums up part of the appeal of his sport when he writes that it is "[A]n acquired taste that reintroduces the chaos of uncertainty back into our well-regulated lives".

Time rules our lives, woven into the very fabric of the universe-from the rising and setting of the sun to the cycles of nature, the thought processes in our brains, and the biorhythms in our day. Nothing so pervades our existence and yet is so difficult to explain. But now, in a series of 24 riveting lectures, you can grasp exactly why - as you take a mind-expanding journey through the past, present, and future, guided by a noted author and scientist.

In the developed world, we’ve reaped the benefits of refrigeration for more than a century, but the costs are catching up with us. We’ve eroded our connection to our food and redefined what “fresh” means. More important, refrigeration is one of the leading contributors to climate change. As the developing world races to build a US-style cold chain, Twilley asks: Can we reduce our dependence on refrigeration? Should we?
