Each of us begins our path in life as a single cell. Just thinking about this common process can fill us with a sense of wonder--and raise a host of questions. How does an egg cell multiply to develop into a human being, an animal, or a plant? How do cells form a brain, a face, a hand? And how does the pattern continue generation after generation? With great insight and unwavering enthusiasm, biology professor Lewis Wolpert presents this complex subject in a "clear and engagingly written book" (Nature) that even the layman can understand. Illuminating the subject with twelve remarkable full-page photographs and numerous informative illustrations, this landmark guide shows the separation, growth, and differentiation of various cells and body parts in the embryonic stage. Simple descriptions of Wolpert's experimental studies offer fascinating insights into topics such as aging, cancer, regeneration, and evolution. Addressing the mysteries that face modern biologists--and all of mankind-- The Triumph of the Embryo is a "fascinating read for anyone curious about the replication and development of life"-- (Science News) . A new preface has been provided by the author.

The subtitle of this volume is exact, for Leo Szilard's work ranged from physics to biology; he crossed over with ease from the world of neutrons to that of neurons, from the nuclei of atoms to the nuclei of cells. At a deeper level, all of these research activities converge, unified as they are by Szilard's interest in the fundamental ideas of order and organization that underlie them all. It is no accident, as Jacques Monod notes in this foreword, that this interest should appear explicitly as the subject of one of his very first papers, and of his last. In the former, concerning the operations of an intelligent being on a thermodynamic system, Szilard anticipated by many years the entropic formulation of information theory, while the latter, "On Memory and Recall," is concerned with the organization of the central nervous system. Szilard's spontaneous, unrepressed flow of ideas was followed by a critical process of selection and refinement, which may account for the relatively small number of published papers—under thirty—found in this collection. The papers are arranged chronologically, and their ordering comprises a resume of Szilard's scientific life. The first group of papers, 1925-1939, all deal with various aspects of physics—thermodynamics, x-ray crystallography, and nuclear physics. The work in this last area includes studies of neutron bombardment and of the possibilities of nuclear fission and chain reactions, which Szilard was among the first to envision. The second group, 1940-1945, comprises the first publication of documents relating to the Manhattan Project, and reflect Szilard's part in it. Most of these documents were previously classified. There are no scientific papers from the years 1946-1948. These were years when Szilard was intensely active in the political and social arena, attempting to bring the atomic bomb under international control. Documents relating to this struggle, and to his earlier leadership in efforts both to undertake the atomic project and to prevent the bomb's use without warning against Japan, will be collected in another volume. It was also during these critical years that Szilard's interest decisively turned from physics to biology. The third group covers the years 1949-1964, when Szilard's interest centered around biological problems. Among these are the regulation of cellular metabolism, antibody formation, the aging process, and the functioning of the central nervous system. A final section of the book reproduces patents and patent applications of historic importance dating from 1923 to 1959, and ranging from the invention of a refrigerator, jointly with Albert Einstein; an application anticipating the cyclotron in 1928; and the general concepts of a nuclear chain reaction in 1934 to the first patent on the nuclear reactor granted jointly to Fermi and Szilard.

This is a collection of essays by the leaders of what has been called the most important development in the theory of knowledge since the 18th century: namely evolutionary epistemology. The motif for this volume is struck in Bartley's opening chapter: Philosophy of biology versus Philosophy of Physics and is continued in Sir Karl Popper's Darwin lecture, Donald T. Campbell's application of Darwinian theory to creative thought processes, and in the debate over the theories of Campbell and Gunter Wachtershauser on the origins of vision.

Psychiatrist Jeffrey Satinover examines recent research reported in medical journals (and the popular press). He finds many of these studies flawed and cites evidence that homosexuality is indeed changeable. He explains how psychology, biology, choice, and habit all interweave to produce deeply imbedded patterns of sexual behavior. The model Dr. Satinover develops is based on modern science and psychological understandings of habit, compulsion, and addiction. Homosexuality, he writes, "is one of the many forms of soul sickness that is innate to our fallen nature."

LIFE AND ENERGY is a brilliant introduction to the chemistry of life. In this highly lucid guide to the dynamics of modern biology, Isaac Asimov deftly explores the most recent discoveries in this constantly surprising field of inquiry. In the first part, he explains the mechanics of the inanimate world, the significance of energy, work, motion, heat, and chemical reaction. He then uses these concepts in the second half to analyze and explain the latest advances in the study of enzymes, amino acids, proteins and the very processes which constitute life itself. In short, Dr. Asimov's keen examination of biology's current desire to isolate and control the very basis of life--the significance of which promises to revolutionize life itself--becomes a fascinating as well as informative excursion. Illustrated with drawings, charts and diagrams.

Hans Jonas, a pupil of Heidegger and a colleague of Hannah Arendt at the New School for Social Research, was one of the most prominent phenomenologists of his generation. This carefully chosen anthology of Jonas's shorter writings - on topics from Jewish philosophy to philosophy of religion to philosophy of biology and social philosophy - reveals their range without obscuring their central unifying thread: that as living, biological beings, we are also beings who die, and who must consider the implications for current and future ethical and social relations.

McCarthy was drafted from his college biology studies and became a member of the Special Forces. Then he is given the opportunity to contact the Chtorr, but when a helicopter crash leaves him and his companions stranded in enemy territory, he must decide whether to communicate with the Chtorr--or kill them!

Cryptozoologicon is a celebration of the myths, legends, evolution and biology of hidden animals. Always sceptical, but always willing to indulge in speculative fun, Cryptozoologicon aims to provide a new way to approach cryptozoology: as fictional biology.

A star writer for the New York Times Styles section captures the follies, frauds, and fanaticism that fuel the American pursuit of youth and beauty in a wickedly revealing excursion into the burgeoning business of cosmetic enhancement. Americans are aging faster and getting fatter than any other population on the planet. At the same time, our popular notions of perfect beauty have become so strict it seems even Barbie wouldn't have a chance of making it into the local beauty pageant. Aging may be a natural fact of life, but for a growing number of Americans its hallmarks--wrinkles, love handles, jiggling flesh--are seen as obstacles to be conquered on the path to lasting, flawless beauty. In Beauty Junkies Alex Kuczynski, whose sly wit and fearless reporting in the Times has won her fans across the country, delivers a fresh and irresistible look at America's increasingly desperate pursuit of ultimate beauty by any means necessary. From a group of high-maintenance New York City women who devote themselves to preserving their looks twenty-four hours a day, to a surgery safari in South Africa complete with after photographs of magically rejuvenated patients posing with wild animals, to a podiatrist's office in Manhattan where a foot face-lift provides women with the right fit for their $700 Jimmy Choos, Kuczynski portrays the all-American quest for self-transformation in all its extremes. In New York, lawyers become Botox junkies in an effort to remain poker-faced. In Los Angeles, women of an uncertain age nip and tuck their most private areas, so that every inch of their bodies is as taut as their lifted faces. Across the country, young women graduating fromhigh school receive gifts of breast implants - from their parents. As medicine and technology stretch the boundaries of biology, Kuczynski asks whether cosmetic surgery might even be part of human evolution, a kind of cosmetic survival of the fittest - or firmest? With incomparable portraits of obsessive patients and the equally obsessed doctors who cater to their dreams, Beauty Junkies examines the hype, the hope, and the questionable ethics surrounding the advent of each new miraculous technique. Lively and entertaining, thought-provoking and disturbing, Beauty Junkies is destined to be one of the most talked-about books of the season.

For millennia, human survival depended on our innate abilities to fight pathogens and repair injuries. Only recently has medical science prolonged longevity and improved quality of life. Physicians and academic researchers contribute to such progress, but the principal contributor is private industry that produces the tools – drugs and medical devices – enabling doctors to prevent and cure disease. Heavy regulation and biology’s complexity and unpredictability make medical innovation extremely difficult and expensive. Pharmaphobia describes how an ideological crusade, stretching over the last quarter century, has used distortion and flawed logic to make medical innovation even harder in a misguided pursuit of theoretical professional purity. Bureaucrats, reporters, politicians, and predatory lawyers have built careers attacking the medical products industry, belittling its critical contributions to medical innovation and accusing it of non-existent malfeasance: overselling product value, flaunting safety and corrupting physicians and academics who partner with it. The mania has imposed “conflict-of-interest” regulations limiting or banning valuable interactions between industry and physicians and researchers and diverting scarce resources from innovation to compliance. The victims are patients suffering from cancer, dementia, and other serious diseases for which new treatments are delayed, reduced, or eliminated as a result of these pointless regulations. With breathtaking detail, Thomas Stossel shows how this attack on doctors who work with industry limits medical innovation and inhibits the process of bringing new products into medical care.

In Pleasure: A Creative Approach to Life , Alexander Lowen shows how the experience of pleasure or pain determines our emotions, thinking, and behavior. Examining the psychology and the biology of pleasure, Alexander Lowen explores its roots in the nature of the body and shows that emotional health means that we are in a state of pleasure - that is, we feel good in our bodies.

As Norbert Hornstein writes in his foreword, "it underestimates Chomsky's impact in linguistics, philosophy, and psychology to describe it as immense." In Rules and Representations , Noam Chomsky lays out many of the concepts that have made his approach to linguistics and human cognition so instrumental to our understanding of language. In this influential and controversial work Chomsky draws on philosophy, biology, and the study of the mind to consider the nature of human cognitive capacities, particularly as they are expressed in language. He arrives at his well-known position that there is a universal grammar, genetically determined, structured in the human mind, and common to all human languages. Aside from his examination of the various principles of the universal grammar--its "rules and representations"--Chomsky considers the biological basis of language capabilities and the possibility of studying mental structures and capacities in the manner of the natural sciences. Finally, he also explores whether there may be similar "grammars" of perception, art, human nature, scientific reasoning, and the unconscious. Based on Chomsky's lively 1978 Woodbridge Lectures, this edition, first published in 1980, contains revised versions of the original lectures and two new essays. It also includes an extensive foreword by Norbert Hornstein, discussing Chomsky's ideas and their wide-ranging impact.

Genetics promises to provide one of the most powerful approaches to understanding the functional pathology of the human brain. This book presents a critical review of the evidence for a genetic contribution to common psychiatric conditions and the rarer single-gene disorders that may have psychiatric presentations The first section of the book introduces the reader to molecular biology and the techniques of molecular genetics. The coverage then moves on to consider the genetics of normal and abnormal development, followed by a look at the genetics of abnormal behaviour in adults. This section includes, amongst others, consideration of personality disorders, schizophrenia and the dementias. The final section considers the applications of the work and covers issues such as counselling and ethics, closing with a look to the future. The editors are internationally renowned figures in this field and they have invited a team of equally eminent chapter authors. This will be essential reading for psychiatrists and geneticists and will be essential reading for psychiatrists and geneticists and will be of interest to neurologists, psychologists and neuroscientists.

In The Logic of Life François Jacob looks at the way our understanding of biology has changed since the sixteenth century. He describes four fundamental turning points in the perception of the structure of living things: the discoveries of the functions of organs, cells, chromosomes and genes, and DNA.

the Astonishing Elephant is an unabashed celebration of these mysterious creatures, whose closest living relatives are the dugong and the hyrax. "they have," Alexander writes, "essential nobility,grace, serenity, sagacity, loyalty and playfulness, a simple goodness, a alack of animosity - unless provoked." While she admits elephants can pose particular dangers to unwary humans (she recounts tales of circus trainers of her acquaintance, some of whom fell in action), they are too often the victims in any interaction with people. the elephant's fortunes have long been declining: where only a few thousand years ago several species roamed the earth, by 1980 the combined wild populations in Africa and Asia numbered fewer than 100,000 individuals.

""How many creatures walking on this earth / Have their first being in another form?" the Roman poet Ovid asked two thousand years ago. He could not have known the full extent of the truth: Today, biologists estimate a stunning three-quarters of all animal species on earth undergo some form of metamorphosis. But why do tadpoles transform into frogs, caterpillars into butterflies, elvers into eels, immortal jellyfish from sea sprigs to medusae and back again, growing younger and younger in frigid ocean depths? Why must creatures go through massive destruction and remodeling to become who they are? Tracing a path from Aristotle--who rejected the possibility of metamorphosis--to Darwin to today, historian of science Oren Harman explores that central mystery. Metamorphosis, however, isn't just a biological puzzle: It takes us to the very heart of questions of being and identity, whatever kind of change we may undergo. Metamorphosis is a new classic of natural history: a book that, by unveiling a mystery of nature, causes us to relearn ourselves"--Publisher's description.

Lynn Margulis, one of the most original and perceptive scientific thinkers of our time, and the writer Dorion Sagan here present a selection from their many essays published in the last decade and a half. This collection includes an extraordinary memoir of Margulis' encounter with J. Robert Oppenheimer as well as provocative ideas on Gaia theory, symbiosis, individuality, and the way scientific research is conducted today.
