Earth, born in a nuclear explosion, is a radioactive planet; without radiation, life would not exist. And while radiation can be dangerous, it is also deeply misunderstood and often mistakenly feared. Now Robert Peter Gale, M.D,—the doctor to whom concerned governments turned in the wake of the Chernobyl and Fukushima disasters—in collaboration with medical writer Eric Lax draws on an exceptional depth of knowledge to correct myths and establish facts. Exploring what have become trigger words for anxiety—nuclear energy and nuclear weapons, uranium, plutonium, iodine-131, mammogram, X-ray, CT scan, threats to the food chain—the authors demystify the science and dangers of radiation, and examine its myriad benefits, from safely sterilizing our food to the relatively low-risk fuel alternative of nuclear energy. This is the book for all readers who have asked themselves questions such as: What kinds of radiation, and what degree of exposure, cause cancer? What aftereffects have nuclear accidents and bombs had? Does radiation increase the likelihood of birth defects? And how does radiation work? Hugely illuminating, Radiation is the definitive road map to our post-Chernobyl, post-Fukushima world.

    Lewis Dartnell considers some of the fascinating questions facing researchers today. Could life exist anywhere else in the universe? What might aliens really look like? Dartnell explains why Earth is uniquely suited for life and reveals our profound connection to the cosmos.

    Lehninger Principles of Biochemistry, Fourth Edition brings clarity and coherence to an often unwieldy discipline, while incorporating the field's most important recent developments and applications.

    In this newly revised edition, chapters have been rewritten to accommodate the impact of computer technology and the Internet, not only on the acquisition and analysis of data, but also on its organization and presentation. Alternatives to the use of radiation have been expanded, and figures and illustrations have been redrawn to reflect changes in laboratory equipment and procedures.

    Yet to address the major political and moral questions that face us today, we must acquire an understanding of their biological roots. This magisterial new book by Ernst Mayr will go far to remedy this situation. An eyewitness to this century's relentless biological advance and the creator of some of its most important concepts, Mayr is uniquely qualified to offer a vision of science that places biology firmly at the center, and a vision of biology that restores the primacy of holistic, evolutionary thinking.As he argues persuasively, the physical sciences cannot address many aspects of nature that are unique to life. Living organisms must be understood at every level of organization; they cannot be reduced to the laws of physics and chemistry. Mayr's approach is refreshingly at odds with the reductionist thinking that dominated scientific research earlier in this century, and will help to redirect how people think about the natural world.This Is Biology can also be read as a life history of the discipline--from its roots in the work of Aristotle, through its dormancy during the Scientific Revolution and its flowering in the hands of Darwin, to its spectacular growth with the advent of molecular techniques. Mayr maps out the territorial overlap between biology and the humanities, especially history and ethics, and carefully describes important distinctions between science and other systems of thought, including theology. Both as an overview of the sciences of life and as the culmination of a remarkable life in science, This Is Biology will richly reward professionals and general readers alike.

    Describes how fractals were discovered, explains their unique properties, and discusses the mathematical foundation of fractals.

    We get cancer because we can't avoid it—it's a bug in the system of life itself.Cancer exists in nearly every animal and has afflicted humans as long as our species has walked the earth. In Rebel Cell: Cancer, Evolution, and the New Science of Life's Oldest Betrayal, Kat Arney reveals the secrets of our most formidable medical enemy, most notably the fact that it isn't so much a foreign invader as a double agent: cancer is hardwired into the fundamental processes of life. New evidence shows that this disease is the result of the same evolutionary changes that allowed us to thrive. Evolution helped us outsmart our environment, and it helps cancer outsmart its environment as well—alas, that environment is us.Explaining why "everything we know about cancer is wrong," Arney, a geneticist and award-winning science writer, guides readers with her trademark wit and clarity through the latest research into the cellular mavericks that rebel against the rigid biological "society" of the body and make a leap towards anarchy.We need to be a lot smarter to defeat such a wily foe—smarter even than Darwin himself. In this new world, where we know that every cancer is unique and can evolve its way out of trouble, the old models of treatment have reached their limits. But we are starting to decipher cancer's secret evolutionary playbook, mapping the landscapes in which these rogue cells survive, thrive, or die, and using this knowledge to predict and confound cancer's next move.Rebel Cell is a story about life and death, hope and hubris, nature and nurture. It's about a new way of thinking about what this disease really is and the role it plays in human life. Above all, it's a story about where cancer came from, where it's going, and how we can stop it.

    In its structure and content, the Anthology is intended to complement the Companion to Bioethics, edited by the same scholars. The Anthology is independent of any particular approach to bioethics. Can be used as a source book to complement the Companion to Bioethics. Probes more deeply than the standard anthologies into the foundations of bioethics. More global in approach than competition.

    We currently see no evidence of any kind indicating that extraterrestrials exist outside of our solar system. But at this moment, millions of engineers, scientists, corporations, universities and entrepreneurs are racing to create the second intelligent species right here on planet earth. And we can see the second intelligent species coming from all directions in the form of self-driving cars, automated call centers, chess-playing and Jeopardy-playing computers that beat all human players, airport kiosks, restaurant tablet systems, etc. The frightening thing is that these robots will soon be eliminating human jobs in startling numbers. The first wave of unemployed workers is likely to be a million truck drivers who are replaced by self-driving trucks. Pilots will be eliminated soon as well. Then, as new computer vision systems come online, we will see tens of millions of workers in retail stores, fast food restaurants and construction sites replaced by robots. Unless we take steps now to change the economy, we will soon have tens of millions of workers who are unemployed and seeking welfare because they will have no other choice. Marshall Brain's new book "The Second Intelligent Species: How Humans Will Become as Irrelevant as Cockroaches" explores how the future will unfold as the second intelligent species emerges. The book answers questions like: - How will new computer vision systems affect the job market? - How many people will become unemployed by the second intelligent species? - What will happen to millions of newly unemployed workers? - How can modern society and modern economies cope with run-away unemployment caused by robots? - What will happen when the first sentient, conscious computer appears? - What moral and ethical principles will guide the second intelligent species? - Why do we see no extraterrestrials in our universe? "The Second Intelligent Species" offers a unique and fascinating look at the future of the human race, and the choices we will need to make to avoid massive unemployment and poverty worldwide as intelligent machines start eliminating millions of jobs.
