A leading neuroscientist argues that the peripheral nervous system, long understood to play a key role in regulating basic bodily functions, also signals the onset of illness.The central nervous system, consisting of the brain and the spinal cord, has long been considered the command center of the body. Yet outside the central nervous system, an elaborate network of nerve cells and fibers extends throughout our bodies, transmitting messages between the brain and other organs. The peripheral nervous system, as it's known, regulates such vital functions as heart rate, digestion, and perspiration and enables us to experience the barrage of sounds, tastes, smells, and other sensory information that surrounds us. But beyond these crucial roles, the peripheral nervous system might do even more: it might warn us of diseases in our future.As Moses Chao argues in Periphery, from Parkinson's disease to autism to dementia, many neurological conditions emerge not in the brain but rather within the peripheral nervous system, in the dense network of nerves that wrap around the gastrointestinal tract. What's more, dysfunctions of the peripheral nervous system can signal the onset of disease decades before symptoms like tremor or memory loss occur. Fortunately, unlike nerves in the brain and spinal cord, peripheral nerves can heal and regenerate in response to injury and aging. The therapeutic implications are remarkable. Chao shows how, with a better understanding of the peripheral nervous system, we could not only predict and treat neurological diseases long before their onset, but possibly prevent them altogether.Full of new ideas and bold interpretations of the latest data, Periphery opens exciting avenues for medical research while deepening our understanding of a crucial yet underappreciated biological system.

Nematodes are small multicellular organisms that have been used as biological models since the 1960s. For example, Caenorhabditis elegans is a free-living nematode worm, about 1mm in length, that lives in temperate soil environments. It is made up of about 1000 cells, and has a short life cycle of only two weeks. It was the first multicellular organism to have its whole genome sequenced. The book summarizes the importance of nematodes as model organisms in the fields of genetics, developmental biology, neurobiology, pharmacology, nutrition, ecology and parasitology. Of interest to a broad audience across a wide spectrum of disciplines, this book is useful for biologists working on comparative studies to investigate biological processes across organisms; medical scientists and pharmacologists for exploration of drugs and medicine (including the use of genome editing to eliminate diseases); ecologists considering nematodes as indicators for environment changes; and parasitologists for host-parasite interactions. Many other researchers can use this book as a benchmark for the broad implications of nematology research on other aspects of science.

People have searched for the fountain of youth everywhere from Bimini to St. Augustine. But for a steadfast group of scientists, the secret to a long life lies elsewhere: in the lowly lab worm. By suppressing the function of just a few key genes, these scientists were able to lengthen worms'lifespans up to tenfold, while also controlling the onset of many of the physical problems that beset old age. As the global population ages, the potential impact of this discovery on society is vast—as is the potential for profit. 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.

An argument that achieving millennial life spans or monumental intellects will destroy values that give meaning to human lives.Proposals to make us smarter than the greatest geniuses or to add thousands of years to our life spans seem fit only for the spam folder or trash can. And yet this is what contemporary advocates of radical enhancement offer in all seriousness. They present a variety of technologies and therapies that will expand our capacities far beyond what is currently possible for human beings. In Humanity's End, Nicholas Agar argues against radical enhancement, describing its destructive consequences. Agar examines the proposals of four prominent radical enhancers: Ray Kurzweil, who argues that technology will enable our escape from human biology; Aubrey de Grey, who calls for anti-aging therapies that will achieve “longevity escape velocity”; Nick Bostrom, who defends the morality and rationality of enhancement; and James Hughes, who envisions a harmonious democracy of the enhanced and the unenhanced. Agar argues that the outcomes of radical enhancement could be darker than the rosy futures described by these thinkers. The most dramatic means of enhancing our cognitive powers could in fact kill us; the radical extension of our life span could eliminate experiences of great value from our lives; and a situation in which some humans are radically enhanced and others are not could lead to tyranny of posthumans over humans.

An individual's healthspan can be defined as the length of time an individual is able to maintain good health. In 2007, over one hundred experts and researchers from public and private institutions across the nation convened to find new ways of addressing the human healthspan and the elusive nature of aging. Experts in public health, bioengineering, neuroscience and gerontology discussed how stress and lifestyle influence the decline of health at older ages. Other discussions focused on the integration of technology in the quality of life, gerontology, regenerative medicine and life expectancy with regard to social and behavioral traits. Still, other groups explored topics such as the cellular and molecular mechanisms of biological aging, the effects of exercise on the human healthspan, and changes in social context to enhance functional status of the elderly. Most importantly, experts agreed that it was imperative to ensure that the elderly have access to medical services by establishing relationships with health care and insurance providers.

'Many scientists today are working to retard the aging process in humans so as to increase both life expectancy and the quality of life. Over the past decade impressive results have been achieved in targeting the mechanisms and pathways of aging. In The Quest for Human Longevity, Lewis D. Solomon considers these scientific studies by exploring the principal biomedical anti-aging techniques. The book also considers cutting edge research on mental enhancements and assesses the scientific doubts of skeptics. The Quest for Human Longevity is also about business. Solomon examines eight corporations pursuing various age-related interventions, profiling their scientific founders and top executives, and examining personnel, intellectual property, and financing for each firm. Academic scientists form the link between research and commerce. Solomon notes that the involvement of university scientists and researchers follows one of two models. The first is a traditional model in which scientists leave academia to work for a corporation or remain in academia and obtain business support for their research. The second is a modern model in which scientists use their intellectual property as a catalyst for acquiring equity interests in the firms they organize. Critics have pointed to the dangers of commercialized science, but Solomon's analysis, on balance, finds that the benefits outweigh the costs and that problems of secrecy and conflicts of interest can be addressed. If scientists succeed in unlocking the secrets of aging and developing drugs or therapies that will allow us to live decades longer, the consequences for society will include profound social, political, economic, and ethical questions. Solomon deals with the public policy aspects of significant life extension and looks at the conflict between those who advocate the acceptance of mortality and the partisans of life. The Quest for Human Longevity will be of interest to policymakers, sociologists, scientists, and studen'

With the decoding of the human genome, researchers can now read the script in which evolution has written the program for the design and operation of the human body. A new generation of medical treatments is at hand. Researchers are developing therapies so powerful that there is now no evident obstacle to the ancient goal of conquering most major diseases. Nicholas Wade has covered the sequencing of the genome, as well as other health and science stories, for The New York Times, in the course of which he has interviewed many of the principal researchers in the field. In this book he describes what the genome means for the health of present and future generations. Someday soon physicians will have access to DNA chips that, from a drop of blood, will screen a person's genes for all the diseases to which he or she may be genetically vulnerable. From full knowledge of the instruction manual of the human body, provided by the genome, pharmaceutical companies hope to develop a new generation of sophisticated drugs; one of the first genome-derived drugs is already undergoing clinical trials. Another vital tool will be regenerative medicine, a new kind of therapy in which new organs and tissues will be grown from a patient's own cells to replace those that are old or diseased. With the help of DNA chips, medical researchers will soon be able to diagnose diseases such as cancer much more precisely and to tailor specific treatments for each patient. Individualized medicine will also become an important part of the pharmaceutical world. Many drugs will be prescribed based on information from DNA chips that identify which of a range of drugs is best for each patient, as well as which drugs are likely to cause side effects. The medicine of the post-genomic era will be customized for a patient's genetic make-up, providing treatments based on a precise understanding of the mechanism of disease. Life Script describes a future in which good health, even perfect health, may become the standard for everyone -- at every age.
