With BPA in baby bottles, mercury in fish, and lead in computer monitors, the world has become a toxic place. But as Emily Monosson demonstrates in her groundbreaking new book, it has always been toxic. When oxygen first developed in Earth's atmosphere, it threatened the very existence of life: now we literally can't live without it. According to Monosson, examining how life adapted to such early threats can teach us a great deal about today's (and tomorrow's) most dangerous contaminants. While the study of evolution has advanced many other sciences, from conservation biology to medicine, the field of toxicology has yet to embrace this critical approach. In Evolution in a Toxic World, Monosson seeks to change that. She traces the development of life's defense systems—the mechanisms that transform, excrete, and stow away potentially harmful chemicals—frommore thanthree billion years ago to today. Beginning with our earliest ancestors' response to ultraviolet radiation, Monosson explores the evolution of chemical defenses such as antioxidants, metal binding proteins, detoxification, and cell death. As we alter the world's chemistry, these defenses often become overwhelmed faster than our bodies can adapt. But studying how our complex internal defense network currently operates, and how it came to be that way, may allow us to predict how it will react to novel and existing chemicals. This understanding could lead to not onlybetter management and preventative measures, but possibly treatment of current diseases. Development of that knowledge starts with this pioneering book.

Gonorrhea. Bed bugs. Weeds. Salamanders. People. All are evolving, some surprisingly rapidly, in response to our chemical age. In Unnatural Selection, Emily Monosson shows how our drugs, pesticides, and pollution are exerting intense selection pressure on all manner of species. And we humans might not like the result. Monosson reveals that the very code of life is more fluid than once imagined. When our powerful chemicals put the pressure on to evolve or die, beneficial traits can sweep rapidly through a population. Species with explosive population growth--the bugs, bacteria, and weeds--tend to thrive, while bigger, slower-to-reproduce creatures, like ourselves, are more likely to succumb. Unnatural Selection is eye-opening and more than a little disquieting. But it also suggests how we might lessen our impact: manage pests without creating super bugs; protect individuals from disease without inviting epidemics; and benefit from technology without threatening the health of our children.

Researchers in the field of ecological genomics aim to determine how a genome or a population of genomes interacts with its environment across ecological and evolutionary timescales. Ecological genomics is trans-disciplinary by nature. Ecologists have turned to genomics to be able to elucidate the mechanistic bases of the biodiversity their research tries to understand. Genomicists have turned to ecology in order to better explain the functional cellular and molecular variation they observed in their model organisms. We provide an advanced-level book that covers this recent research and proposes future development for this field. A synthesis of the field of ecological genomics emerges from this volume. Ecological Genomics covers a wide array of organisms (microbes, plants and animals) in order to be able to identify central concepts that motivate and derive from recent investigations in different branches of the tree of life. Ecological Genomics covers 3 fields of research that have most benefited from the recent technological and conceptual developments in the field of ecological genomics: the study of life-history evolution and its impact of genome architectures; the study of the genomic bases of phenotypic plasticity and the study of the genomic bases of adaptation and speciation.

We rely on chemical cures to keep our bodies free from disease and our farm fields free from bugs and weeds. While human and agricultural health are rarely considered together, both are based on the same ecology, and both are being threatened by organisms that have evolved to resist our antibiotics and pesticides. Fortunately scientists are finding new solutions that work with, rather than against, nature. There are viruses that bust apart bacteria; insect pheromones that throw crop destroying moths into a misguided sexual frenzy; plant genes edited to protect against disease; and a resurgence of the ancient practice of fecal transplants. In this hopeful book, Monosson offers a fascinating look into the future of natural defenses.

In today's world, everyone carries a toxic load of dozens of industrially produced chemicals in their bloodstream. Not only do these adversely affect the health of adults and children, but also, and more worryingly, they damage the development of unborn infants. The amniotic fluid of pregnant women has been found to contain a variety of chemicals, such as pesticides, plasticizers, disinfectant products, flame-retardants, surfactants and UV filters, many of which interfere with fetal physiology, especially thyroid hormone action. Thyroid hormone is vital for brain development, particularly for the fetus during pregnancy and for toddlers. In fact, children born to women who lack this thyroid hormone (or who are unwittingly exposed to thyroid-disrupting chemicals) have lower IQs and more neurodevelopmental problems. Evolution of the human brain has involved multiple changes and processes dependent on thyroid hormone. The urgent question thus arises: Is chemical pollution poisoning brain development and reversing evolution's most outstanding achievement: the human brain? And if so, as this book convincingly illuminates, what can be done about it both collectively and individually? Toxic Cocktail provides a clear view of how many environmental chemicals interfere with brain development. As a result, this book looks at how we define and test IQ, the evidence for IQ loss, and how chemical pollution and thyroid hormone disruption can be actors in this process, as well as increasing neurodevelopmental disease risk.

A few years ago, journalist McKay Jenkins had a tumour removed from his abdomen. At the hospital, he was asked a lot of odd questions by two researchers: How much exposure had he had to toxic chemicals and other contaminants? Asbestos dust? Vinyl chlorine? Pesticides? Jenkins, a clean living kind of guy, suddenly realised he'd spent his life marinating in toxins, from his wall-to-wall carpeting, to his dryer sheets, to his drinking water. In ContamiNation, he exposes the toxins that are present in our everyday lives, and shows how we can avoid them.

In spite of decades of research on toxicants, along with the growing role of scientific expertise in public policy and the unprecedented rise in the number of national and international institutions dealing with environmental health issues, problems surrounding contaminants and their effects on health have never appeared so important, sometimes to the point of appearing insurmountable. This calls for a reconsideration of the roles of scientific knowledge and expertise in the definition and management of toxic issues, which this book seeks to do. It looks at complex historical, social, and political dynamics, made up of public controversies, environmental and health crises, economic interests, and political responses, and demonstrates how and to what extent scientific knowledge about toxicants has been caught between scientific, economic, and political imperatives.

As the amount of information in biology expands dramatically, it becomes increasingly important for textbooks to distill the vast amount of scientific knowledge into concise principles and enduring concepts.As with previous editions, Molecular Biology of the Cell, Sixth Edition accomplishes this goal with clear writing and beautiful illustrations. The Sixth Edition has been extensively revised and updated with the latest research in the field of cell biology, and it provides an exceptional framework for teaching and learning. The entire illustration program has been greatly enhanced.Protein structures better illustrate structure–function relationships, icons are simpler and more consistent within and between chapters, and micrographs have been refreshed and updated with newer, clearer, or better images. As a new feature, each chapter now contains intriguing openended questions highlighting “What We Don’t Know,” introducing students to challenging areas of future research. Updated end-of-chapter problems reflect new research discussed in the text, and these problems have been expanded to all chapters by adding questions on developmental biology, tissues and stem cells, pathogens, and the immune system.
