We’ll look at what identical twins can teach us about the epigenetic effects of our environment and experiences, why certain genes are 'switched on' or off at various stages of embryonic development, and how scientists have reversed the specialization of cells to clone frogs from a single gut cell. In Introducing Epigenetics, Cath Ennis and Oliver Pugh pull apart the double helix, examining how the epigenetic building blocks and messengers that interpret and edit our genes help to make us, well, us.

    Poisons permeate our world. They are in the environment, the workplace, the home. They are in food, our favorite whiskey, medicine, well water. They have been used to cure disease as well as to incapacitate and kill. They smooth wrinkles, block pain, stimulate, and enhance athletic ability. In this entertaining and fact-filled book, science writer Peter Macinnis considers poisons in all their aspects. He recounts stories of the celebrated poisoners in history and literature, from Nero to Thomas Wainewright, and from the death of Socrates to Hamlet and Peter Pan. He discusses the sources of various poisons-from cyanide to strychnine, from Botox to ricin and Sarin gas-as well as their detection. Then he analyzes the science of their action in the body and their uses in medicine, cosmetics, war, and terrorism. With wit and precision, he weighs such questions as: Was Lincoln's volatility caused by mercury poisoning? Was Jack the Ripper an arsenic eater? Can wallpaper kill? For anyone who has ever wondered and been afraid to ask, here is a rich miscellany for your secret questions about toxins.

    Unlocking the secrets of our genomes opens the door to understanding why we are the way we are and potentially fixing what ails us, from cancer and diabetes to obesity and male pattern baldness. But what exactly will happen to this information? Will it be a boon or just another marketing tool?Here Is a Human Being is the first in-depth look at personal genomics—its larger-than-life research subjects; its entrepreneurs and do-it-yourselfers; its technology developers; and the bewildered physicians and regulators who must negotiate with it—and what it means to be a “public genome” in a world where privacy is already under siege.

    Written for both the casual reader and the science buff hungry for new information, The Vision Revolution is a resource that dispels commonly believed perceptions about sight and offers answers drawn from the field’s most recent research.Changizi focuses on four “why” questions:1. Why do we see in color?2. Why do our eyes face forward?3. Why do we see illusions?4. Why does reading come so naturally to us?Why Do We See in Color?It was commonly believed that color vision evolved to help our primitive ancestors identify ripe fruit. Changizi says we should look closer to home: ourselves. Human color vision evolved to give us greater insights into the mental states and health of other people. People who can see color changes in skin have an advantage over their color-blind counterparts; they can see when people are blushing with embarrassment, purple-faced with exertion or the reddening of rashes. Changizi’s research reveals that the cones in our eyes that allow us to see color are exquisitely designed exactly for seeing color changes in the skin. And it’s no coincidence that the primates with color vision are the ones with bare spots on their faces and other body parts; Changizi shows that the development of color vision in higher primates closely parallels the loss of facial hair, culminating in the near hairlessness and highly developed color vision of humans.Why Do Our Eyes Face Forward?Forward-facing eyes set us apart from most mammals, and there is much dispute as to why we have them. While some speculate that we evolved this feature to give us depth perception available through stereo vision, this type of vision only allows us to see short distances, and we already have other mechanisms that help us to estimate distance. Changizi’s research shows that with two forward-facing eyes, primates and humans have an x-ray ability. Specifically, we’re able to see through the cluttered leaves of the forest environment in which we evolved. This feature helps primates see their targets in a crowded, encroached environment. To see how this works, hold a finger in front of your eyes. You’ll find that you’re able to look “through” it, at what is beyond your finger. One of the most amazing feats of two forward-facing eyes? Our views aren’t blocked by our noses, beaks, etc.Why Do We See Illusions?We evolved to see moving objects, not where they are, but where they are going to be. Without this ability, we couldn’t catch a ball because the brain’s ability to process visual information isn’t fast enough to allow us to put our hands in the right place to intersect for a rapidly approaching baseball. “If our brains simply created a perception of the way the world was at the time light hit the eye, then by the time that perception was elicited—which takes about a tenth of a second for the brain to do—time would have marched on, and the perception would be of the recent past,” Changizi explains. Simply put, illusions occur when our brain is tricked into thinking that a stationary two-dimensional picture has an element that is moving. Our brains project the “moving” element into the future and, as a result, we don’t see what’s on the page, but what our brain thinks will be the case a fraction of a second into the future.Why Does Reading Come So Naturally to Us?We can read faster than we can hear, which is odd, considering that reading is relatively recent, and we’ve evolved to process speech for millions of years. Changizi’s research reveals that language has been carefully designed to tap in to elements of the visual processing center that have evolved for tens of millions of years. Visual signs of all languages are shaped like objects in nature, Changizi says, because we have evolved to see nature easily. “People have noticed letters in nature for some time, and there are artists who have a spent a lot of time photographing Latin letters in natural scenes or on butterfly wings,” Changizi says. “For example, if you look at an upper corner of the room you are in, you will see three contours meeting at a point, making a shape close to that of a ‘Y.’“ The Vision Revolution expands upon how our ancestors found the shapes of Latin letters and delves into how visual signs can have similar shapes even though their inspirations come from very different environments.In addition to these four areas, The Vision Revolution explores other phenomena such as cyclopses, peeking and many more you hadn’t even thought to wonder about. Changizi shows how deeply involved these evolutionary aspects of our vision are in why we see the way we do—and what the future holds for us.“…to understand how culture interacts with vision, one must understand not just the eye’s design, but the actual mechanisms we have evolved,” Changizi says, “for culture can tap in to both the designed responses of our brains and the unintended responses.”The Vision Revolution is a book that finally gives attention to what before has been largely neglected by other works on human vision—a book that looks at the “why.”

    With black and white illustrations. "Here is a new collection of Gould's unexpected connections between evolution and all manner of subjects, literature high among them. Gathered from his monthly column in "Natural History" magazine, these articles should delight, surprise, and inform his vast readership, as have his six prior volumes of essays. Somehow the light bulb pops on every month as his deadline approaches, some glowing fact pulled out of memory--often a line from Shakespeare or Tennyson--that illumines a generality Gould wishes to discuss. "Nature, red in tooth and claw" (Lord Alfred's line) induces dilations on the extent science can inform moral matters (not much, Gould believes); a remembrance of the infamous Wansee protocol prompts Gould's denunciation of the genocidal looting of evolutionary theory and, by extension, its vulnerability to ignoramuses in general. These two examples of the Gouldian essay method, fortunately, don't foreshadow a gloomy parade of topics: Gould can as easily alight at the fun house where mass culture absorbs ideas about evolution through movies of monsters run amok from Frankenstein to Jurassic Park. In other essays, he plunges directly into matters of evolutionary interpretation but customarily employs a literary twist: who else but Gould could link Edgar Allan Poe with his own area of professional eminence, the paleontology of snails? A discovery awaits in every essay--in every haystack--which solidifies Gould as one of the most eloquent science popularizers writing today."--"Booklist"

    Yet brain scientists have uncovered details every business leader, parent, and teacher should know—like the need for physical activity to get your brain working its best.How do we learn? What exactly do sleep and stress do to our brains? Why is multi-tasking a myth? Why is it so easy to forget—and so important to repeat new knowledge? Is it true that men and women have different brains?In Brain Rules, Dr. John Medina, a molecular biologist, shares his lifelong interest in how the brain sciences might influence the way we teach our children and the way we work. In each chapter, he describes a brain rule—what scientists know for sure about how our brains work—and then offers transformative ideas for our daily lives.Medina’s fascinating stories and infectious sense of humor breathe life into brain science. You’ll learn why Michael Jordan was no good at baseball. You’ll peer over a surgeon’s shoulder as he proves that most of us have a Jennifer Aniston neuron. You’ll meet a boy who has an amazing memory for music but can’t tie his own shoes.You will discover how:Every brain is wired differentlyExercise improves cognitionWe are designed to never stop learning and exploringMemories are volatileSleep is powerfully linked with the ability to learnVision trumps all of the other sensesStress changes the way we learnIn the end, you’ll understand how your brain really works—and how to get the most out of it.

    We know that accidents happen, but we believe we are on earth for a reason. Until now, most scientists have argued that science and faith occupy distinct arenas. Francis Collins, a former atheist as a science student who converted to faith as he became a doctor, is about to change that. Collins's faith in God has been confirmed and enhanced by the revolutionary discoveries in biology that he has helped to oversee. He has absorbed the arguments for atheism of many scientists and pundits, and he can refute them. Darwinian evolution occurs, yet, as he explains, it cannot fully explain human nature - evolution can and must be directed by God. He offers an inspiring tour of the human genome to show the miraculous nature of God's instruction book.

    The Human Genome Project finished sequencing human DNA. It seemed it was only a matter of time until we had all the answers to the secrets of life on this planet. The cutting-edge of biology, however, is telling us that we still don't even know all of the questions. How is it that, despite each cell in your body carrying exactly the same DNA, you don't have teeth growing out of your eyeballs or toenails on your liver? How is it that identical twins share exactly the same DNA and yet can exhibit dramatic differences in the way that they live and grow? It turns out that cells read the genetic code in DNA more like a script to be interpreted than a mould that replicates the same result each time. This is epigenetics and it's the fastest-moving field in biology today. The Epigenetics Revolution traces the thrilling path this discipline has taken over the last twenty years. Biologist Nessa Carey deftly explains such diverse phenomena as how queen bees and ants control their colonies, why tortoiseshell cats are always female, why some plants need a period of cold before they can flower, why we age, develop disease and become addicted to drugs, and much more. Most excitingly, Carey reveals the amazing possibilities for humankind that epigenetics offers for us all - and in the surprisingly near future.

    Judy Mikovits is a modern-day Rosalind Franklin, a brilliant researcher shaking up the old boys’ club of science with her groundbreaking discoveries. And like many women who have trespassed into the world of men, she uncovered decades-old secrets that many would prefer to stay buried. From her doctoral thesis, which changed the treatment of HIV-AIDS, saving the lives of millions, including basketball great Magic Johnson, to her spectacular discovery of a new family of human retroviruses, and her latest research which points to a new golden age of health, Dr. Mikovits has always been on the leading edge of science. With the brilliant wit one might expect if Erin Brockovich had a doctorate in molecular biology, Dr. Mikovits has seen the best and worst of science. When she was part of the research community that turned HIV-AIDS from a fatal disease into a manageable one, she saw science at its best. But when her investigations questioned whether the use of animal tissue in medical research were unleashing devastating plagues of chronic diseases, such as autism and chronic fatigue syndrome, she saw science at its worst. If her suspicions are correct, we are looking at a complete realignment of scientific practices, including how we study and treat human disease. Recounting her nearly four decades in science, including her collaboration of more than thirty-five years with Dr. Frank Ruscetti, one of the founders of the field of human retrovirology, this is a behind the scenes look at the issues and egos which will determine the future health of humanity.

    Loosely based on the form of Chaucer's Canterbury Tales, Dawkins's Tale takes us modern humans back through four billion years of life on our planet. As the pilgrimage progresses, we join with other organisms at the forty "rendezvous points" where we find a common ancestor. The band of pilgrims swells into a vast crowd as we join first with other primates, then with other mammals, and so on back to the first primordial organism.Dawkins's brilliant, inventive approach allows us to view the connections between ourselves and all other life in a bracingly novel way. It also lets him shed bright new light on the most compelling aspects of evolutionary history and theory: sexual selection, speciation, convergent evolution, extinction, genetics, plate tectonics, geographical dispersal, and more. The Ancestor's Tale is at once a far-reaching survey of the latest, best thinking on biology and a fascinating history of life on Earth. Here Dawkins shows us how remarkable we are, how astonishing our history, and how intimate our relationship with the rest of the living world.

    Fascinating... may presage a paradigm shift in medicine." --Kirkus Reviews (starred review)Teeming with information and big ideas... Outstanding."--Booklist (starred review) The origin of asthma, autism, Alzheimer's, allergies, cancer, heart disease, obesity, and even some kinds of depression is now clear. Award-winning researcher on the microbiome, professor Rodney Dietert presents a new paradigm in human biology that has emerged in the midst of the ongoing global epidemic of noncommunicable diseases.The Human Superorganism makes a sweeping, paradigm-shifting argument. It demolishes two fundamental beliefs that have blinkered all medical thinking until very recently: 1) Humans are better off as pure organisms free of foreign microbes; and 2) the human genome is the key to future medical advances. The microorganisms that we have sought to eliminate have been there for centuries supporting our ancestors. They comprise as much as 90 percent of the cells in and on our bodies--a staggering percentage! More than a thousand species of them live inside us, on our skin, and on our very eyelashes. Yet we have now significantly reduced their power and in doing so have sparked an epidemic of noncommunicable diseases--which now account for 63 percent of all human deaths.Ultimately, this book is not just about microbes; it is about a different way to view humans. The story that Dietert tells of where the new biology comes from, how it works, and the ways in which it affects your life is fascinating, authoritative, and revolutionary. Dietert identifies foods that best serve you, the superorganism; not new fad foods but ancient foods that have made sense for millennia. He explains protective measures against unsafe chemicals and drugs. He offers an empowering self-care guide and the blueprint for a revolution in public health. We are not what we have been taught. Each of us is a superorganism. The best path to a healthy life is through recognizing that profound truth.
