    It is within the realm of possibility that their work may usher in a change in global economics as profound as the Industrial Revolution. As may be expected, press reports dealing with asteroid mining have been numerous, ranging in scope from short and breezy to broad and serious, and in quality from accurate to impressionistic to simply uninformed. There is good reason to be curious about what may be the biggest game-changer in human economic history. And there is good reason to look closely at the underlying science and engineering that form the foundation of this work.

    A story of defiance and determination by a controversial scientist, this is Lee Berger's own take on finding Homo naledi, an all-new species on the human family tree and one of the greatest discoveries of the 21st century.In 2013, Berger, a National Geographic Explorer-in-Residence, caught wind of a cache of bones in a hard-to-reach underground cave in South Africa. He put out a call around the world for petite collaborators--men and women small and adventurous enough to be able to squeeze through 8-inch tunnels to reach a sunless cave 40 feet underground. With this team of "underground astronauts," Berger made the discovery of a lifetime: hundreds of prehistoric bones, including entire skeletons of at least 15 individuals, all perhaps two million years old. Their features combined those of known prehominids like Lucy, the famous Australopithecus, with those more human than anything ever before seen in prehistoric remains. Berger's team had discovered an all new species, and they called it Homo naledi.The cave quickly proved to be the richest primitive hominid site ever discovered, full of implications that shake the very foundation of how we define what makes us human. Did this species come before, during, or after the emergence of Homo sapiens on our evolutionary tree? How did the cave come to contain nothing but the remains of these individuals? Did they bury their dead? If so, they must have had a level of self-knowledge, including an awareness of death. And yet those are the very characteristics used to define what makes us human. Did an equally advanced species inhabit Earth with us, or before us? Berger does not hesitate to address all these questions.Berger is a charming and controversial figure, and some colleagues question his interpretation of this and other finds. But in these pages, this charismatic and visionary paleontologist counters their arguments and tells his personal story: a rich and readable narrative about science, exploration, and what it means to be human.

    The awesome journey of life's transformation from the first microbes 4 billion years ago to Homo sapiens today is an epic that we are only now beginning to grasp. Magnificent and bizarre, it is the story of how we got here, what we left behind, and what we brought with us. We all know about evolution, but it still seems absurd that our ancestors were fish. Darwin's idea of natural selection was the key to solving generation-to-generation evolution -- microevolution -- but it could only point us toward a complete explanation, still to come, of the engines of macroevolution, the transformation of body shapes across millions of years. Now, drawing on the latest fossil discoveries and breakthrough scientific analysis, Carl Zimmer reveals how macroevolution works. Escorting us along the trail of discovery up to the current dramatic research in paleontology, ecology, genetics, and embryology, Zimmer shows how scientists today are unveiling the secrets of life that biologists struggled with two centuries ago. In this book, you will find a dazzling, brash literary talent and a rigorous scientific sensibility gracefully brought together. Carl Zimmer provides a comprehensive, lucid, and authoritative answer to the mystery of how nature actually made itself.

     She was a gifted midwestern beauty, the daughter of Ohio State University's marching band director: to dance on Broadway. Soon after high school graduation, Catherine left Columbus for New York City, determined to be a star. Three years later, she was dead -- murdered in cold blood in her East Side apartment. The shocking revelations that emerged from the police investigation made tabloid headlines: few knew that the struggling artist paid her bills by dancing in a topless club. But there was another hidden facet to Catherine's life -- a shattering love triangle with two men, one of whom would ultimately be convicted of her brutal stabbing death. It's a chilling account of obsession, violence, and the surprising, minute evidence on which the entire case hinged. For a talented young woman reaching for the top, and the heartbroken family she left behind, it is truly the death of a dream.

    It tells the story of Charles Sternberg and his life-long passion for dinosaur fossils. Sternberg writes vividly of his discoveries and of the hardships and dangers of collecting fossils in the wild West. His book is an extraordinary record of science in the rough and a unique view of life on the frontier.

    Global sea levels, as the result of rapidly melting polar ice rose by more than 300 feet in a very short period of time, causing the planet to become unstable.In Egypt, Peru, Bolivia, Lebanon and other locations we see the existence of ancient damaged but very sophisticated megalithic stone structures which we would be hard pressed to re-create today. They hint that once upon a time one or "Atlantean" civilizations indeed did exist

    After a painstaking wait, Nate is even more surprised when it hatches and out pops a baby triceratops that he names Uncle Beazley! But when Nate decides to keep the dino and raise it on his own, he has no idea what he's getting himself into. As Uncle Beazley grows, Nate and his family realize they are not equipped to take care of a full-sized dinosaur, and so with the help of their scientist friend, Nate and Uncle Beazley set off for the NationalMuseum in Washington, D.C., on the hunt for the perfect home for a modern-day dinosaur---then the real trouble begins!The Enormous Egg was originally published in 1956 and has been a classic in children's literature ever since. This brand new edition features amazing new illustrations from Eisner-award winning graphic novelist Mark Crilley (creator of Akiko and Miki Falls).

    It hold the remains of an ancient sea where dozens of strange creatures lived—a forgotten corner of evolution preserved in awesome detail. In this book Stephen Jay Gould explores what the Burgess Shale tells us about evolution and the nature of history.

    Often black and white or tinted sepia, these remarkable images have been taken mainly in zoos or wildlife parks, and in some cases depict the last known individual of the species. Lost Animals is a unique photographic record of extinction, presented by a world authority on vanished animals. Richly illustrated throughout, this handsome book features photographs dating from around 1870 to as recently as 2004, the year that witnessed the demise of the Hawaiian Po'ouli. From a mother Thylacine and her pups to birds such as the Heath Hen and the Carolina Parakeet, Errol Fuller tells the story of each animal, explains why it became extinct, and discusses the circumstances surrounding the photography.Covering 28 extinct species, Lost Animals includes familiar examples like the last Passenger Pigeon, Martha, and one of the last Ivory-billed Woodpeckers, photographed as it peers quizzically at the hat of one of the biologists who has just ringed it. But the book includes rare images as well, many never before published. Collected together here for the first time, these photographs provide a tangible link to animals that have now vanished forever, in a book that brings the past to life while delivering a warning for the future.Poignant and compelling, Lost Animals also includes a concise introduction that looks at the earliest days of animal photography, and an appendix of drawings and paintings of the species covered.

    Many of the events in his life, and the characters whom he knew, are described in his books: this is the story of the man who wrote them.

    To determine these patterns, they needed to hear many different examples of authentic speech by various speakers of different ages and in different regions. They eventually discovered that one of the easiest ways to convince older local residents to give them lengthy examples of their natural speech was to ask the residents to tell their favorite stories to the brothers. As the Grimms Brothers recorded the style of speech of the speaker for their research (which eventually led to the formulation of Grimm's Law), they also recorded the various stories that they were told, and eventually published them in 1817.

    William began to explore science books in his village library, looking for a solution. There, he came up with the idea that would change his family's life forever: he could build a windmill.
