We are in the midst of a revolution. It is a scientific revolution built upon the tools of molecular biology, with which we probe and prod the living world in ways unimaginable a few decades ago. Need to track a bacterium at the root of a hospital outbreak? No problem: the offending germ's complete genetic profile can be obtained in 24 hours. We insert human DNA into E. coli bacteria to produce our insulin. It is natural to look at biotechnology in the 21st century with a mix of wonder and fear. But biotechnology is not as 'unnatural' as one might think. All living organisms use the same molecular processes to replicate their genetic material and the same basic code to 'read' their genes. The similarities can be seen in their DNA. Here, John Archibald shows how evolution has been 'plugging-and-playing' with the subcellular components of life from the very beginning and continues to do so today. For evidence, we need look no further than the inner workings of our own cells. Molecular biology has allowed us to gaze back more than three billion years, revealing the microbial mergers and acquisitions that underpin the development of complex life. One Plus One Equals One tells the story of how we have come to this realization and its implications.

There’s never been a better time to “be prepared.” Matthew Stein’s comprehensive primer on sustainable living skills—from food and water to shelter and energy to first-aid and crisis-management skills—prepares you to embark on the path toward sustainability. But unlike any other book, Stein not only shows you how to live “green” in seemingly stable times, but to live in the face of potential disasters, lasting days or years, coming in the form of social upheaval, economic meltdown, or environmental catastrophe. When Technology Fails covers the gamut. You’ll learn how to start a fire and keep warm if you’ve been left temporarily homeless, as well as the basics of installing a renewable energy system for your home or business. You’ll learn how to find and sterilize water in the face of utility failure, as well as practical information for dealing with water-quality issues even when the public tap water is still flowing. You’ll learn alternative techniques for healing equally suited to an era of profit-driven malpractice as to situations of social calamity. Each chapter (a survey of the risks to the status quo; supplies and preparation for short- and long-term emergencies; emergency measures for survival; water; food; shelter; clothing; first aid, low-tech medicine, and healing; energy, heat, and power; metalworking; utensils and storage; low-tech chemistry; and engineering, machines, and materials) offers the same approach, describing skills for self-reliance in good times and bad. Fully revised and expanded—the first edition was written pre-9/11 and pre-Katrina, when few Americans took the risk of social disruption seriously—When Technology Fails ends on a positive, proactive note with a new chapter on "Making the Shift to Sustainability," which offers practical suggestions for changing our world on personal, community and global levels.

This newly revised edition of Global Environment discusses the major elements of the geochemical cycles and global fluxes found in the atmosphere, land, lakes, rivers, biota, and oceans, as well as the human effects on these fluxes. Retaining the strengths of the original edition while incorporating the latest discoveries, this textbook takes an integrated, multidisciplinary, and global approach to geochemistry and environmental problems and introduces fundamental concepts of meteorology, surficial geology (weathering, erosion, and sedimentation), biogeochemistry, limnology, and oceanography. New concepts and information in this updated edition include changes of atmospheric carbon dioxide over geologic time, major advances in the study of chemical weathering of rocks, ocean acidification, and important environmental problems, such as the amelioration of the acid rain problem due to reduction in sulfur deposition, problems with nitrification of soils and lakes, and eutrophication of rivers and estuaries. An expanded chapter explores atmospheric chemistry and changing climate, with the most up-to-date statistics on CO2, the carbon cycle, other greenhouse gases, and the ozone hole. Only requiring a fundamental understanding in elementary chemistry, yet taking into account extensive and current data, this text is ideal for students in environmental geochemistry, environmental geology, global change, biogeochemistry, water pollution, geochemical cycles, chemical oceanography, and geohydrology, and serves as a valuable reference for researchers working on global geochemical and environmental issues. Revised edition takes a close look at global fluxes involving the atmosphere, land, lakes, rivers, biota, and oceans, and the human effects on these fluxes Detailed discussion of basic concepts including meteorology, surficial geology (weathering, erosion, and sedimentation), biogeochemistry, limnology, and oceanography An expanded up-to-date chapter on atmospheric chemistry and changing climate, including CO2, other greenhouse gases, and ozone Presentation of major advances in the study of chemical weathering Discussion of current environmental topics Global coverage of environmental problems involving water Some images inside the book are unavailable due to digital copyright restrictions.

An integrative approach to healing chronic autoimmune conditions by a doctor, researcher, and sufferer of progressive multiple sclerosis (MS) whose TEDx talk is already a web sensation Like many physicians, Dr. Terry Wahls focused on treating her patients’ ailments with drugs or surgical procedures—until she was diagnosed with multiple sclerosis (MS) in 2000. Within three years, her back and stomach muscles had weakened to the point where she needed a tilt-recline wheelchair. Conventional medical treatments were failing her, and she feared that she would be bedridden for the rest of her life. Dr. Wahls began studying the latest research on autoimmune disease and brain biology, and decided to get her vitamins, minerals, antioxidants, and essential fatty acids from the food she ate rather than pills and supplements. Dr. Wahls adopted the nutrient-rich paleo diet, gradually refining and integrating it into a regimen of neuromuscular stimulation. First, she walked slowly, then steadily, and then she biked eighteen miles in a single day. In November 2011, Dr. Wahls shared her remarkable recovery in a TEDx talk that immediately went viral. Now, in The Wahls Protocol, she shares the details of the protocol that allowed her to reverse many of her symptoms, get back to her life, and embark on a new mission: to share the Wahls Protocol with others suffering from the ravages of multiple sclerosis and other autoimmune conditions.

Clay for the Potter tells the remarkable story of Sarah Mitchell Gettys. From her childhood years on the windswept Colorado plains, a time of struggling farmers and one-room schoolhouses, through her travels around the world as a young woman and educator, all the way to her later years as an entrepreneur and business owner, Sarah's is a uniquely American story that perfectly reflects the changing landscape of our nation. "Life is like building a house. Each wall is made up of memories, which are a result of the decisions we make and the actions we take, as we go through life. We ourselves are the builders and eventually we are the ones who have no choice but to live in the house we have built for ourselves. My "walls" embrace me with warmth and a great deal of love. I am a happy camper."

Essential Hypertension As Adaptation To Excess Gravitational Stress

Spaceflight studies have demonstrated that adaptation to gravitational stress after prolonged microgravity includes sympathetic activation, water retention, and arterial pressure increase, i.e. a process very similar to development of essential hypertension, which from this perspective looks like an advanced stage of that adaptation with sympathetic hyperactivity, vasoconstriction, volume overload, and arterial hypertension in case of some further increase in gravitational stress. This book contains theoretical analysis of human cardiovascular function in real conditions of Earth gravitational field leading to the scientifically sound hypothesis of essential hypertension as advanced stage of natural adaptation of the human cardiovascular system to abnormally increased gravitational stress associated with modern 'sitting' lifestyle. Also clinical and experimental data are presented supporting this hypothesis according to comprehensive literature search. In upright position gravitation shifts blood downwards emptying upper body and reducing blood supply to the brain. Passively filling heart cannot pump blood out of the lower into the upper body. Compensation is provided through lower body vasoconstriction and circulating volume increase. The gravitational stress (GS) in the cardiovascular system in an upright position may be defined as amount of work necessary to return the blood upward and maintain adequate upper-body circulation calculated as the product of the gravitational potential (Ugr=g*h) and the mass of blood shifted by gravitation: GS=U*Mshift. In a complex vascular network, this blood shift is actually a function of time, estimated in a first approximation as Mshift(t)=(Ugr*t)/Rd (Rd: the resistance to downward blood flow) so that gravitational stress is proportional to the time spent upright GS=U*Mshift(t)=(Ugr2*t)/Rd=(g2*h2*t)/Rd. From this analysis typical for modern life regular, prolonged sitting should cause a significant increase in gravitational stress in the cardiovascular system, requiring advanced antigravitational response with sympathetic hyperactivity, vasoconstriction, volume overload, and arterial hypertension. The hypertensive effect of prolonged sitting has been directly demonstrated in several clinical studies. Numerous population studies demonstrated higher prevalence of hypertension for occupations with predominantly sitting posture during worktime. Thus, essential hypertension in scientifically sound way is explained as adaptation to increased gravitational stress resulted from modern «sitting» lifestyle. This gravitational hypothesis of essential hypertension fully integrates two existed major concepts of sympathetic hyperactivity and abnormal sodium reabsorption as complementary mechanisms of antigravitational response but contrary to them offers a way to complete healing of the disease through elimination of the primary factor of abnormal gravitational stress.
