He shows rather that new tools are more often the sparks that ignite scientific discovery. Such tool-driven revolutions have profound social consequences--the invention of the telescope turning the Medieval world view upside down, the widespread use of household appliances in the 1950s replacing servants, to cite just two examples. In looking ahead, Dyson suggests that solar energy, genetics, and the Internet will have similarly transformative effects, with the potential to produce a more just and equitable society. Solar power could bring electricity to even the poorest, most remote areas of third world nations, allowing everyone access to the vast stores of information on the Internet and effectively ending the cultural isolation of the poorest countries. Similarly, breakthroughs in genetics may well enable us to give our children healthier lives and grow more efficient crops, thus restoring the economic and human vitality of village cultures devalued and dislocated by the global market.Written with passionate conviction about the ethical uses of science, The Sun, the Genome, and the Internet is both a brilliant reinterpretation of the scientific process and a challenge to use new technologies to close, rather than widen, the gap between rich and poor.

    It focuses throughout on phylogenetic trees.

    Thus, the literature on speciation, as well as the number of researchers and students working in this area, has grown explosively. Despite thesedevelopments, there has been no book-length treatment of speciation in many years. As a result, both the seasoned scholar and the newcomer to evolutionary biology had no ready guide to the recent literature on speciation--a body of work that is enormous, scattered, and increasingly technical.Although several excellent symposium volumes have recently appeared, these collections do not provide a unified, critical, and up-to-date overview of the field. Speciation is designed to fill this gap.Aimed at professional biologists, graduate students, and advanced undergraduates, Speciation covers both plants and animals (the first book on this subject to do so), and deals with all relevant areas of research, including biogeography, field work, systematics, theory, and genetic and molecularstudies. It gives special emphasis to topics that are either controversial or the subject of active research, including sympatric speciation, reinforcement, the role of hybridization in speciation, the search for genes causing reproductive isolation, and mounting evidence for the role of natural andsexual selection in the origin of species. The authors do not hesitate to take stands on these and other controversial issues. This critical and scholarly book will be invaluable to researchers in evolutionary biology and is also ideal for a graduate-level course on speciation.

    And when he finds this God he tells his brothers, saying: “If I had not come and spoken to you, you would have no sin, but now you have no excuse for your sins.” God reveals himself to man as his eternal contemporary, saying: “Unless you believe that I am he, you will die in your sins,” but man finds it almost impossible to keep the tense. He thinks of God in the third person, addresses him in the second person, but can only know God in a first person, present tense experience. Just imagine - no one can sin until God reveals himself to the individual in a first person, present tense experience. Only then can man have no excuse for his sin. And when one who finds God tells his brothers, he receives no greater reception than the first one did, because they see him as a man of flesh and blood, and cannot see this invisible being who says: “I came down from heaven.” Man is looking for Christ to come from without, but his revelation is whispered from within.

    In One Renegade Cell, Weinberg presents a state-of-the-art account of how cancer begins and how, one day, it will be cured.

    Many studies have supported this, proving that life expectancy is 75 to 90 percent due to habits and only 10 to 25 percent due to genetics. This means that someone who is genetically destined to die at age 100 may not live past age 60 because of poor habits and lifestyle choices that cause accelerated aging and premature death. Conversely, a person can live to 100 and be functionally healthy. In this highly anticipated follow-up, Diana Schwarzbein, M.D., goes beyond the diet she introduced in her first book—which literally helped thousands of people lose weight—and offers a personalized anti-aging program for readers to heal their metabolisms and stop advanced aging in its tracks. Weaving in groundbreaking research and provocative case studies—including her own regeneration and that of her clients—she leads readers through a series of eye-opening questionnaires, which identify where they are on their path to either accelerated or healthy aging. Based on readers’ answers, she leads them to the “how-to” sections, which explain, in easy-to-follow and personalized detail, the steps they need to take to restore healthy functioning. For each unique situation, she covers five areas: Nutrition , Hormone Replacement Therapy (if needed), Tapering Off Toxic Chemicals or Avoiding Them Completely , Cross-Training Exercises and Stress Management. The Schwarzbein Principle II is sure to follow the success of the first book and will help people live a more healthful lifestyle by embracing a regeneration process to prevent and reverse accelerated aging.

    Nathan has been lying to his wife about a serious medical condition. Marsha, recently separated from her husband, cannot resist telling her children negative things about their father. What is the role of therapy in these situations? Trained to strive for neutrality and to focus strictly on the clients' needs, most therapists generally consider moral issues such as fairness, truthfulness, and obligation beyond their domain. Now, an award-winning psychologist and family therapist criticizes psychotherapy's overemphasis on individual self-interest and calls for a sense of moral responsibility in therapy.
