In this book you will see how commonly performed operations can be found to be useless or even harmful when properly evaluated. That these claims come from an experienced, practicing orthopedic surgeon who performs many of these operations himself, makes the unsettling argument particularly compelling. Of course no surgeon is recommending invasive surgery in bad faith, but Ian Harris argues that the evidence for the success for many common operations, including knee arthroscopies, back fusion or cardiac stenting, become current accepted practice without full examination of the evidence.

    The fastest bird is showing us how to solve a century-old engineering mystery. The oldest tree is giving us insights into climate change. The loudest whale is offering clues about the impact of solar storms.For a long time, scientists ignored superlative life forms as outliers. Increasingly, though, researchers are coming to see great value in studying plants and animals that exist on the outermost edges of the bell curve.As it turns out, there’s a lot of value in paying close attention to the “oddballs” nature has to offer.Go for a swim with a ghost shark, the slowest-evolving creature known to humankind, which is teaching us new ways to think about immunity. Get to know the axolotl, which has the longest-known genome and may hold the secret to cellular regeneration. Learn about Monorhaphis chuni, the oldest discovered animal, which is providing insights into the connection between our terrestrial and aquatic worlds.Superlative is the story of extreme evolution, and what we can learn from it about ourselves, our planet, and the cosmos. It's a tale of crazy-fast cheetahs and super-strong beetles, of microbacteria and enormous plants, of whip-smart dolphins and killer snakes.This book will inspire you to change the way you think about the world and your relationship to everything in it.

    But if you think humans have a tough time dating, try having to do it while being hunted down by predators, against a backdrop of unpredictable and life-threatening conditions. The animal kingdom is a wild place – and it’s got mating habits to match. The sex lives of our animal cousins are fiendishly difficult, infinitely varied, often incredibly violent — and absolutely fascinating.In Wild Sex, Dr. Carin Bondar takes readers on an enthralling tour of the animal kingdom as she explores the diverse world of sex in the wild. She looks at the evolution of sexual organs (and how they’ve shaped social hierarchies), tactics of seduction, and the mechanics of sex. She investigates a wide range of topics, from whether animals experience pleasure from sex to what happens when females hold the reproductive power. Along the way, she encounters razor-sharp penises, murderous carnal cannibals, and spontaneous chemical warfare in an epic battle between the sexes.The resulting book is titillating, exhilarating, amusing, petrifying, alluring — and absolutely guaranteed to make you think about sex in a whole new way.

    Seeing Trees celebrates seldom seen but easily observable tree traits and invites you to watch trees with the same care and sensitivity that birdwatchers watch birds. Many people, for example, are surprised to learn that oaks and maples have flowers, much less flowers that are astonishingly beautiful when viewed up close. Focusing on widely grown trees, this captivating book describes the rewards of careful and regular tree viewing, outlines strategies for improving your observations, and describes some of the most visually interesting tree structures, including leaves, flowers, buds, leaf scars, twigs, and bark. In-depth profiles of ten familiar species—including such beloved trees as white oak, southern magnolia, white pine, and tulip poplar—show you how to recognize and understand many of their most compelling (but usually overlooked) physical features.

    If you read one book on human origins, this should be it' Ian Morris, author of Why the West Rules - For Now 'The who, what, where, when and how of human evolution, from one of the world's experts on the dating of prehistoric fossils' Steve Brusatte, author of The Rise and Fall of the Dinosaurs50,000 years ago, we were not the only species of human in the world. There were at least four others, including the Neanderthals, Homo floresiensis, Homo luzonesis and the Denisovans. At the forefront of the latter's ground-breaking discovery was Oxford Professor Tom Higham. In The World Before Us, he explains the scientific and technological advancements - in radiocarbon dating and ancient DNA, for example - that allowed each of these discoveries to be made, enabling us to be more accurate in our predictions about not just how long ago these other humans lived, but how they lived, interacted and live on in our genes today. This is the story of us, told for the first time with its full cast of characters.'The application of new genetic science to pre-history is analogous to how the telescope transformed astronomy. Tom Higham brings us to the frontier of recent discoveries with a book that is both gripping and fun' Paul Collier, author of The Bottom Billion'This exciting book shows that we now have a revolutionary new tool for reconstructing the human past: DNA from minute pieces of tooth and bone, and even from the dirt on the floor of caves' David Abulafia, author of The Boundless Sea'The remarkable new science of palaeoanthropology, from lab bench to trench' Rebecca Wragg Sykes, author of Kindred'Higham's thrilling account makes readers feel as if they were participating themselves in the extraordinary series of events that in the last few years has revealed our long-lost cousins' David Reich, author of Who We Are and How We Got Here'A brilliant distillation of the ideas and discoveries revolutionising our understanding of human evolution' Chris Gosden, author of The History of Magic

    A Fellow at Oxford and a leading chemist, he has won admiration for his precise, lucid, and yet rigorous explanations of science. Now he turns his forensic mind to the greatest--and most controversial--questions of human existence: birth, death, the origin of reality, and its end.In On Being, Atkins makes a provocative contribution to the great debate between religion and science. Atkins makes his position clear from the very first sentence: The scientific method can shed light on every and any concept, even those that have troubled humans since the earliest stirrings of consciousness, he writes. He takes a materialist approach to the great questions of being that have inspired myth and religion, seeking to dispel their mystery without diminishing their grandeur. In placing scientific knowledge in such cosmic perspective, he takes us on an often dizzying tour of existence. For example, he argues that the substrate of existence is nothing at all. The total electrical charge of the universe, among other things, must be nothing--zero--he writes, or else the universe would have blasted itself apart. Charge was not created at the creation: electrical Nothing separated into equal and opposite charges. He explores breathtaking questions--asking the purpose of the universe--with wit and learning, touching on Sanskrit scriptures and John Updike along the way.

    We are but one more model, and there is no evidence evolution has stopped. So unless you think Rush Limbaugh and Howard Stern are the be all and end all of creation, and it just does not get any better, then one has to ask what is next? Juan Enriquez and Steve Gullans, two of the world's most eminent science authors, researchers, and entrepreneurs, answer this by taking you into a world where humans increasingly shape their environment, their own selves, and other species. It is a world where our bodies harbor 100 times more microbial cells than human cells, a place where a gene cocktail may allow many more to climb an 8,000 meter peak without oxygen, and where, given the right drug, one could have a 77 percent chance of becoming a centenarian. By the end you will see a broad, and sometimes scary, map of life science driven change. Not just our bodies will be altered but our core religious, government, and social structures as humankind makes the transition to a new species, a Homo evolutis, which directly and deliberately controls its own evolution and that of many other species.

    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.

    Lavishly illustrated with over sixty original artworks, All Yesterdays aims to challenge our notions of how prehistoric animals looked and behaved. As a critical exploration of palaeontological art, All Yesterdays asks questions about what is probable, what is possible, and what is commonly ignored.Written by palaeozoologist Darren Naish, and palaeontological artists John Conway and C.M. Kosemen, All Yesterdays is scientifically rigorous and artistically imaginative in its approach to fossils of the past - and those of the future.

    Written by one of the world's foremost paleontologists, Prehistoric Mammals gives children a rare glimpse at a world gone by in a stunningly illustrated, incredibly comprehensive reference book.

    The easy kind, practiced by ants, shrimp, Welsh corgis -- and us -- is innate. What innate calculating skills do we humans have? Leaving aside built-in mathematics, such as the visual system, ordinary people do just fine when faced with mathematical tasks in the course of the day. Yet when they are confronted with the same tasks presented as "math," their accuracy often drops. But if we have innate mathematical ability, why do we have to teach math and why do most of us find it so hard to learn? Are there tricks or strategies that the ordinary person can do to improve mathematical ability? Can we improve our math skills by learning from dogs, cats, and other creatures that "do math"? The answer to each of these questions is a qualified yes. All these examples of animal math suggest that if we want to do better in the formal kind of math, we should see how it arises from natural mathematics. From NPR's "Math Guy" -- The Math Instinct will provide even the most number-phobic among us with confidence in our own mathematical abilities.
