A Summer Reading Pick for President Barack Obama, Bill Gates, and Mark Zuckerberg
From a renowned historian comes a groundbreaking narrative of humanity’s creation and evolution—a #1 international bestseller—that explores the ways in which biology and history have defined us and enhanced our understanding of what it means to be “human.”
One hundred thousand years ago, at least six different species of humans inhabited Earth. Yet today there is only one—homo sapiens. What happened to the others? And what may happen to us?
Most books about the history of humanity pursue either a historical or a biological approach, but Dr. Yuval Noah Harari breaks the mold with this highly original book that begins about 70,000 years ago with the appearance of modern cognition. From examining the role evolving humans have played in the global ecosystem to charting the rise of empires, Sapiens integrates history and science to reconsider accepted narratives, connect past developments with contemporary concerns, and examine specific events within the context of larger ideas.
Dr. Harari also compels us to look ahead, because over the last few decades humans have begun to bend laws of natural selection that have governed life for the past four billion years. We are acquiring the ability to design not only the world around us, but also ourselves. Where is this leading us, and what do we want to become?
Featuring 27 photographs, 6 maps, and 25 illustrations/diagrams, this provocative and insightful work is sure to spark debate and is essential reading for aficionados of Jared Diamond, James Gleick, Matt Ridley, Robert Wright, and Sharon Moalem.
In Cat Sense, renowned anthrozoologist John Bradshaw takes us further into the mind of the domestic cat than ever before, using cutting-edge scientific research to dispel the myths and explain the true nature of our feline friends. Tracing the cat's evolution from lone predator to domesticated companion, Bradshaw shows that although cats and humans have been living together for at least eight thousand years, cats remain independent, predatory, and wary of contact with their own kind, qualities that often clash with our modern lifestyles. Cats still have three out of four paws firmly planted in the wild, and within only a few generations can easily revert back to the independent way of life that was the exclusive preserve of their predecessors some 10,000 years ago. Cats are astonishingly flexible, and given the right environment they can adapt to a life of domesticity with their owners-but to continue do so, they will increasingly need our help. If we're to live in harmony with our cats, Bradshaw explains, we first need to understand their inherited quirks: understanding their body language, keeping their environments-however small-sufficiently interesting, and becoming more proactive in managing both their natural hunting instincts and their relationships with other cats.
A must-read for any cat lover, Cat Sense offers humane, penetrating insights about the domestic cat that challenge our most basic assumptions and promise to dramatically improve our pets' lives-and ours.
#1 NEW YORK TIMES BESTSELLER
Her name was Henrietta Lacks, but scientists know her as HeLa. She was a poor black tobacco farmer whose cells—taken without her knowledge in 1951—became one of the most important tools in medicine, vital for developing the polio vaccine, cloning, gene mapping, and more. Henrietta's cells have been bought and sold by the billions, yet she remains virtually unknown, and her family can't afford health insurance. This phenomenal New York Times bestseller tells a riveting story of the collision between ethics, race, and medicine; of scientific discovery and faith healing; and of a daughter consumed with questions about the mother she never knew.
By showing us the true nature of chance and revealing the psychological illusions that cause us to misjudge the world around us, Mlodinow gives us the tools we need to make more informed decisions. From the classroom to the courtroom and from financial markets to supermarkets, Mlodinow's intriguing and illuminating look at how randomness, chance, and probability affect our daily lives will intrigue, awe, and inspire.

The Earth teems with life: in its oceans, forests, skies and cities. Yet there’s a black hole at the heart of biology. We do not know why complex life is the way it is, or, for that matter, how life first began. In The Vital Question, award-winning author and biochemist Nick Lane radically reframes evolutionary history, putting forward a solution to conundrums that have puzzled generations of scientists.
For two and a half billion years, from the very origins of life, single-celled organisms such as bacteria evolved without changing their basic form. Then, on just one occasion in four billion years, they made the jump to complexity. All complex life, from mushrooms to man, shares puzzling features, such as sex, which are unknown in bacteria. How and why did this radical transformation happen?
The answer, Lane argues, lies in energy: all life on Earth lives off a voltage with the strength of a lightning bolt. Building on the pillars of evolutionary theory, Lane’s hypothesis draws on cutting-edge research into the link between energy and cell biology, in order to deliver a compelling account of evolution from the very origins of life to the emergence of multicellular organisms, while offering deep insights into our own lives and deaths.
Both rigorous and enchanting, The Vital Question provides a solution to life’s vital question: why are we as we are, and indeed, why are we here at all?
In the current debate about creationism and intelligent design, there is an element of the controversy that is rarely mentioned-the evidence. Yet the proof of evolution by natural selection is vast, varied, and magnificent. In this succinct and accessible summary of the facts supporting the theory of natural selection, Jerry A. Coyne dispels common misunderstandings and fears about evolution and clearly confirms the scientific truth that supports this amazing process of change. Weaving together the many threads of modern work in genetics, paleontology, geology, molecular biology, and anatomy that demonstrate the "indelible stamp" of the processes first proposed by Darwin, Why Evolution Is True does not aim to prove creationism wrong. Rather, by using irrefutable evidence, it sets out to prove evolution right.
"Intelligent Design" is being taught in our schools; educators are being asked to "teach the controversy" behind evolutionary theory. There is no controversy. Dawkins sifts through rich layers of scientific evidence—from living examples of natural selection to clues in the fossil record; from natural clocks that mark the vast epochs wherein evolution ran its course to the intricacies of developing embryos; from plate tectonics to molecular genetics—to make the airtight case that "we find ourselves perched on one tiny twig in the midst of a blossoming and flourishing tree of life and it is no accident, but the direct consequence of evolution by non-random selection." His unjaded passion for the natural world turns what might have been a negative argument, exposing the absurdities of the creationist position, into a positive offering to the reader: nothing less than a master’s vision of life, in all its splendor.
Early studies of the human brain used a simple method: wait for misfortune to strike -- strokes, seizures, infectious diseases, horrendous accidents -- and see how victims coped. In many cases their survival was miraculous, if puzzling. Observers were amazed by the transformations that took place when different parts of the brain were destroyed, altering victims' personalities. Parents suddenly couldn't recognize their own children. Pillars of the community became pathological liars. Some people couldn't speak but could still sing.
In The Tale of the Dueling Neurosurgeons, Sam Kean travels through time with stories of neurological curiosities: phantom limbs, Siamese twin brains, viruses that eat patients' memories, blind people who see through their tongues. He weaves these narratives together with prose that makes the pages fly by, to create a story of discovery that reaches back to the 1500s and the high-profile jousting accident that inspired this book's title.* With the lucid, masterful explanations and razor-sharp wit his fans have come to expect, Kean explores the brain's secret passageways and recounts the forgotten tales of the ordinary people whose struggles, resilience, and deep humanity made neuroscience possible.
*"The Tale of the Dueling Neurosurgeons" refers to the case of French king Henri II, who in 1559 was lanced through the skull during a joust, resulting in one of the most significant cases in neuroscience history. For hundreds of years scientists have gained important lessons from traumatic accidents and illnesses, and such misfortunes still represent their greatest resource for discovery.
It took Charles Darwin more than twenty years to publish this book, in part because he realized that it would ignite a firestorm of controversy. On the Origin of Species first appeared in 1859, and it remains a continuing source of conflict to this day. Even among those who reject its ideas, however, the work's impact is undeniable. In science, philosophy, and theology, this is a book that changed the world.
In addition to its status as the focus of a dramatic turning point in scientific thought, On the Origin of Species stands as a remarkably readable study. Carefully reasoned and well-documented in its arguments, the work offers coherent views of natural selection, adaptation, the struggle for existence, survival of the fittest, and other concepts that form the foundation of modern evolutionary theory. This volume is a reprint of the critically acclaimed first edition.
In The Disappearing Spoon, bestselling author Sam Kean unlocked the mysteries of the periodic table. In THE VIOLINIST'S THUMB, he explores the wonders of the magical building block of life: DNA.
There are genes to explain crazy cat ladies, why other people have no fingerprints, and why some people survive nuclear bombs. Genes illuminate everything from JFK's bronze skin (it wasn't a tan) to Einstein's genius. They prove that Neanderthals and humans bred thousands of years more recently than any of us would feel comfortable thinking. They can even allow some people, because of the exceptional flexibility of their thumbs and fingers, to become truly singular violinists.
Kean's vibrant storytelling once again makes science entertaining, explaining human history and whimsy while showing how DNA will influence our species' future.
In her third enthralling book about the brain, Judith Horstman takes us on a lively tour of our most important sex and love organ and the whole smorgasbord of our many kinds of love-from the bonding of parent and child to the passion of erotic love, the affectionate love of companionship, the role of animals in our lives, and the love of God.
Drawing on the latest neuroscience, she explores why and how we are born to love-how we're hardwired to crave the companionship of others, and how very badly things can go without love. Among the findings: parental love makes our brain bigger, sex and orgasm make it healthier, social isolation makes it miserable-and although the craving for romantic love can be described as an addiction, friendship may actually be the most important loving relationship of your life.
Based on recent studies and articles culled from the prestigious Scientific American and Scientific American Mind magazines, The Scientific American Book of Love, Sex, and the Brain offers a fascinating look at how the brain controls our loving relationships, most intimate moments, and our deep and basic need for connection.
The common ancestry of all humanity
The role of genes in sickness and health
Debates over the use of genetic technology
Written in an engaging, narrative manner, this concise introduction is an ideal starting point for anyone who wants to know more about genes, DNA, and the genetic ties that bind us all.
We all have a rage circuit we can’t fully control once it is engaged as R. Douglas Fields, PhD, reveals in this essential book for our time. The daily headlines are filled with examples of otherwise rational people with no history of violence or mental illness suddenly snapping in a domestic dispute, an altercation with police, or road rage attack. We all wish to believe that we are in control of our actions, but the fact is, in certain circumstances we are not. The sad truth is that the right trigger in the right circumstance can unleash a fit of rage in almost anyone.
But there is a twist: Essentially the same pathway in the brain that can result in a violent outburst can also enable us to act heroically and altruistically before our conscious brain knows what we are doing. Think of the stranger who dives into a frigid winter lake to save a drowning child.
Dr. Fields is an internationally recognized neurobiologist and authority on the brain and the cellular mechanisms of memory. He has spent years trying to understand the biological basis of rage and anomalous violence, and he has concluded that our culture’s understanding of the problem is based on an erroneous assumption: that rage attacks are the product of morally or mentally defective individuals, rather than a capacity that we all possess.
Fields shows that violent behavior is the result of the clash between our evolutionary hardwiring and triggers in our contemporary world. Our personal space is more crowded than ever, we get less sleep, and we just aren't as fit as our ancestors. We need to understand how the hardwiring works and how to recognize the nine triggers. With a totally new perspective, engaging narrative, and practical advice, Why We Snap uncovers the biological roots of the rage response and how we can protect ourselves—and others.

It is now evident that the "illegal biologicals" he referred to included the pathogenic agents which have led to the AIDS epidemic and other world health crisis.
In The Extremely Unfortunate Skull Valley Incident the authors trace history of the secret war against and the terrible experiments performed upon their own citizens as well as the Third World populations. But Skull Valley does more than that. In their research the father-son team discovered the links between AIDS and many other diseases now increasing dramatically worldwide. Chief among these is myalgic encephalomyelitis/fibromyalgia dismissively labelled " chronic fatigue syndrome" by the government researchers.
In addition to AIDS and ME/FM the Scotts also demonstrate the etiological links to other neurosystemic degenerative diseases such as Alzheimer's, multiple sclerosis, Parkinson's, diabetes, schizophrenia, Crohn's-colitis, etc. All are said to be "of no known cause and having no known cure". Researchers Donald and William Scott have discovered that there is a "known cause" and there may well be a cure.
The cause is a little known organism called the "mycoplasma" which has the capacity to access genetically pre-disposed cells and to destroy them by up-taking pre-formed sterols. This process is the "degeneration" which characterizes all of the diseases under study. When the cells of the endocrine system are destroyed by a sufficient concentration of mycoplasmas, the balance of the physiological balance is altered and the immune system loses its ability to defend the infected victim, and co-factors such as the human immune-deficiency virus (HIV), and those with cause pneumonia, are free to have their way, leading to full-blown AIDS.

“Rich in dexterous innuendo, laugh-out-loud humor and illuminating fact. It’s compulsively readable.” —Los Angeles Times Book Review In ?Bonk, ?the best-selling author of Stiff turns her outrageous curiosity and insight on the most alluring scientific subject of all: sex. Can a person think herself to orgasm? Why doesn't Viagra help women-or, for that matter, pandas? Can a dead man get an erection? Is vaginal orgasm a myth? Mary Roach shows us how and why sexual arousal and orgasm-two of the most complex, delightful, and amazing scientific phenomena on earth-can be so hard to achieve and what science is doing to make the bedroom a more satisfying place.
Exploring the natural history of these animals, the Coppingers explain how the village dogs of Vietnam, India, Africa, and Mexico are strikingly similar. These feral dogs, argue the Coppingers, are in fact the truly archetypal dogs, nearly uniform in size and shape and incredibly self-sufficient. Drawing on nearly five decades of research, they show how dogs actually domesticated themselves in order to become such efficient scavengers of human refuse. The Coppingers also examine the behavioral characteristics that enable dogs to live successfully and to reproduce, unconstrained by humans, in environments that we ordinarily do not think of as dog friendly.
Providing a fascinating exploration of what it actually means—genetically and behaviorally—to be a dog, What Is a Dog? will undoubtedly change the way any beagle or bulldog owner will reflect on their four-legged friend.
Science is on the cusp of a revolutionary breakthrough. We now understand more about aging—and how to prevent and reverse it—than ever before.
In recent years, our understanding of the nature of aging has grown exponentially, and dramatic life extension—even age reversal—has moved from science fiction to real possibility.
Dr. Michael Fossel has been in the forefront of aging research for decades and is the author of the definitive textbook on human aging. In The Telomerase Revolution, he takes us on a detailed but highly accessible scientific journey, providing startling insights into the nature of human aging.
Twenty years ago, there was still considerable debate of the nature of human aging, with a variety of competing theories in play. But scientific consensus is forming around the telomere theory of aging. The essence of this theory is that human aging is the result of cellular aging. Every time a cell reproduces, its telomeres (the tips of the chromosomes) shorten. With every shortening of the telomeres, the cell’s ability to repair its molecules decreases. It ages. Human aging is the result of the aging of the body’s trillions of cells.
But some of our cells don’t age. Sex cells and stem cells can reproduce indefinitely, without aging, because they create telomerase. Telomerase re-lengthens the telomeres, keeping these cells young.
The Telomerase Revolution describes how telomerase will soon be used as a powerful therapeutic tool, with the potential to dramatically extend life spans and even reverse human aging. Telomerase-based treatments are already available, and have shown early promise, but much more potent treatments will become available over the next decade.
The Telomerase Revolution is the definitive work on the latest science on human aging, covering both the theory and the clinical implications. It takes the reader to the forefront of the upcoming revolution in human medicine.
You will follow your oxygen atoms through fire and water and from forests to your fingernails. Hydrogen atoms will wriggle into your hair and betray where you live and what you have been drinking. The carbon in your breath will become tree trunks, and the sodium in your tears will link you to long-dead oceans. The nitrogen in your muscles will help to turn the sky blue, the phosphorus in your bones will help to turn the coastal waters of North Carolina green, the calcium in your teeth will crush your food between atoms that were mined by mushrooms, and the iron in your blood will kill microbes as it once killed a star.
You will also discover that much of what death must inevitably do to your body is already happening among many of your atoms at this very moment and that, nonetheless, you and everyone else you know will always exist somewhere in the fabric of the universe.
You are not only made of atoms; you are atoms, and this book, in essence, is an atomic field guide to yourself.

So we've all heard of genes, but how do they actually work?
There are 2.2 metres of DNA inside every one of your cells, encoding roughly 20,000 genes. These are the 'recipes' that tell our cells how to make the building blocks of life, along with myriad control switches ensuring they're turned on and off at the right time and in the right place. But rather than a static string of genetic code, this is a dynamic, writhing biological library. Figuring out how it all works – how your genes build your body – is a major challenge for researchers around the world. And what they're discovering is that far from genes being a fixed, deterministic blueprint, things are much more random and wobbly than anyone expected.
Drawing on stories ranging from six toed cats and stickleback hips to Mickey Mouse mice and zombie genes – told by researchers working at the cutting edge of genetics – Kat Arney explores the mysteries in our genomes with clarity, flair and wit, creating a companion reader to the book of life itself.

Why Size Matters, a pioneering book of big ideas in a compact size, gives size its due by presenting a profound yet lucid overview of what we know about its role in the living world. Bonner argues that size really does matter--that it is the supreme and universal determinant of what any organism can be and do. For example, because tiny creatures are subject primarily to forces of cohesion and larger beasts to gravity, a fly can easily walk up a wall, something we humans cannot even begin to imagine doing.
Bonner introduces us to size through the giants and dwarfs of human, animal, and plant history and then explores questions including the physics of size as it affects biology, the evolution of size over geological time, and the role of size in the function and longevity of living things.
As this elegantly written book shows, size affects life in its every aspect. It is a universal frame from which nothing escapes.
With The Longevity Seekers, science writer Ted Anton takes readers inside this tale that began with worms and branched out to snare innovative minds from California to Crete, investments from big biotech, and endorsements from TV personalities like Oprah and Dr. Oz. Some of the research was remarkable, such as the discovery of an enzyme in humans that stops cells from aging. And some, like an oft-cited study touting the compound resveratrol, found in red wine—proved highly controversial, igniting a science war over truth, credit, and potential profit. As the pace of discovery accelerated, so too did powerful personal rivalries and public fascination, driven by the hope that a longer, healthier life was right around the corner. Anton has spent years interviewing and working with the scientists at the frontier of longevity science, and this book offers a behind-the-scenes look at the state-of-the-art research and the impact it might have on global public health, society, and even our friends and family.
With spectacular science and an unforgettable cast of characters, The Longevity Seekers has all the elements of a great story and sheds light on discoveriesthat could fundamentally reshape human life.
PHILOSOPHERS, THEOLOGIANS, ARTISTS, AND BOY BANDS HAVE WAXED poetic for centuries about the nature of love. But what does the brain have to say about the way we carry our hearts? In the wake of a divorce, science writer and single mother Kayt Sukel made herself a guinea pig in the labs of some unusual love experts to find out. This Is Your Brain on Sex is her lively and hilarious examination of the big questions about love and sex, previously published in hardcover as Dirty Minds.
Each chapter of this edgy romp through the romantic brain looks at a different aspect of love above the belt. What in your brain makes you love someone—or simply lust after them? Why do good girls like bad boys? Is monogamy practical? How thin is that line between love and hate? After reading this gimlet-eyed look at love, sex, and the brain, you’ll never look at romance the same way again.
With The Long and the Short of It, biologist and writer Jonathan Silvertown offers readers a witty and fascinating tour through the scientific study of longevity and aging. Dividing his daunting subject by theme—death, life span, aging, heredity, evolution, and more—Silvertown draws on the latest scientific developments to paint a picture of what we know about how life span, senescence, and death vary within and across species. At every turn, he addresses fascinating questions that have far-reaching implications: What causes aging, and what determines the length of an individual life? What changes have caused the average human life span to increase so dramatically—fifteen minutes per hour—in the past two centuries? If evolution favors those who leave the most descendants, why haven’t we evolved to be immortal? The answers to these puzzles and more emerge from close examination of the whole natural history of life span and aging, from fruit flies, nematodes, redwoods, and much more. The Long and the Short of It pairs a perpetually fascinating topic with a wholly engaging writer, and the result is a supremely accessible book that will reward curious readers of all ages.
The book begins with a general coverage of the characteristics of swine and the swine industry with emphasis on the gastrointestinal tract. It then describes the various classes of nutrients and how these nutrients are metabolized by swine and the factors affecting their utilization. The next section covers the practical aspects of swine nutrition from birth through gestation and lactation in sows and to the feeding of adult boars. The nutritional aspects of the various feedstuffs commonly fed to swine are covered in the following section. The final chapters of the book are devoted to coverage of various techniques used in swine nutrition research.

This volume provides formulas and procedures for determination of sample size required not only for testing equality, but also for testing non-inferiority/superiority, and equivalence (similarity) based on both untransformed (raw) data and log-transformed data under a parallel-group design or a crossover design with equal or unequal ratio of treatment allocations. It contains a comprehensive and unified presentation of statistical procedures for sample size calculation that are commonly employed at various phases of clinical development. Each chapter includes, whenever possible, real examples of clinical studies from therapeutic areas such as cardiovascular, central nervous system, anti-infective, oncology, and women's health to demonstrate the clinical and statistical concepts, interpretations, and their relationships and interactions.
The book highlights statistical procedures for sample size calculation and justification that are commonly employed in clinical research and development. It provides clear, illustrated explanations of how the derived formulas and/or statistical procedures can be used.
Rapid advances in DNA sequencing technology have led to a major change in the way that prokaryotes are classified. Sequence analysis of highly conserved regions of the bacterial genome, such as the small subunit rRNA gene, now provide us with a universal method of estimating the evolutionary relationships among all organisms. Such gene-based phylogenetic classifications have led to many new discoveries about prokaryotes that were not reflected in the classification used in the first edition of the Manual. We now know that the prokaryotes fall into two broad domains: the Archaea and the Bacteria. Whereas the Archaea were once thought of as the more primitive of the prokaryotic lineages, we now realize that they are more closely related to the eukaryotes than to the Bacteria by this measure. We have come to realize that many taxa based on shared phenotypic features may be quite distinct from one another based on phylogenetic evidence. The Chromatium, a genus of anoxygenic photosynthetic bacteria are more closely related to E. coli than to some other lineages of anoxygenic photosynthetic bacteria; Mycoplasma and other cell-wall deficient species are members of the Gram-positive clade; the medically important Chlamydia are aligned with the Planctomyces; and the Clostridium, which form a phenotypically coherent group, fall into more than a dozen phylogenetically disparate groups of Gram-positive bacteria. We have also come to realize that prokaryotes represent one of the major sources of biodiversity in nature and play a major role in the functioning of all ecosystems.
In addition to such fundamental revelations, the widespread application of new methods of classifying prokaryotes has led to an explosive growth in the number of validly published species and higher taxa. Since completion of the first edition of the Manual, the number of published species has more than tripled and has been accompanied by numerous taxonomic realignments that take into consideration newly published findings.
Phylogenetic classification is now broadly accepted as the preferred method of representing taxonomic relationships among prokaryotes and eukaryotes alike. While the evolutionary history of the prokaryotes is far from complete, there is already sufficient data to provide a reasonable view of the major lines of descent of the cultivable species. Although the second edition of the Manual retains it’s unique and highly structured style of presentation of information along genus and species lines, the arrangement of content is along the phylogenetic lines of the small subunit rRNA gene, so that the reader is presented with the information in a more natural, biological perspective. The second edition of the Manual also contains more in-depth ecological information about individual taxa and many new introductory essays.
In the preface to the first edition of Bergey’s Manual of Determinative Bacteriology, published in 1923, one of the stated goals of that work was to "stimulate efforts to perfect the classification of bacteria..." The editors of the first edition regarded the Manual as "a progress report leading to a more satisfactory classification in the future" rather than a definitive classification. Bergey’s Manual Trust continues in this tradition and recognizes that, for the Manual to remain scientifically meaningful and useful to the scientific community, it is time for the new edition.
Overview of the second edition of the Manual
As before, the Manual is subdivided into multiple volumes and each genus occurs as a separate chapter with introductory text provided at higher taxonomic levels. The second edition differs from the first in that clinically relevant species are not grouped together into two volumes. Rather, these taxa appear in their proper phylogenetic place. The text is arranged to follow the lineages defined by the large-scale phylogenetic trees maintained by the Ribosomal Database Project and the ARB Project to which a formalized, hierarchical taxonomy and nomenclature have been applied. As volume 2 goes to press, the taxonomy encompasses 6466 species that are assigned to 26 phyla, 41 classes, 88 orders, 240 families and 1194 genera. Each volume contains a collection of introductory essays on the history and use of the Manual; a detailed discussion of the prokaryotic domains; overviews of the classification, identification, and naming of prokaryotes; prokaryotic ecology and phylogeny; the role of culture collections in microbiology; and intellectual property of prokaryotes. Each volume also includes taxon specific essays and a detailed road map that presents the reader with a broad view of how the entire edition will be arranged, a mapping of phylogenetic groups to the phenotypic groups used in the first edition (Volume 1), or an update of newly published taxa and combinations appearing in print since the preceding volume (Volumes 2-5). The details of each volume in print (Volume 1), in press (Volume 2) or in preparation (Volumes 3-5) follow.
