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.

    Zimmer, an award-winning science writer, takes readers on a fascinating journey into the latest discoveries about evolution. In the Canadian Arctic, paleontologists unearth fossils documenting the move of our ancestors from sea to land. In the outback of Australia, a zoologist tracks some of the world's deadliest snakes to decipher the 100-million-year evolution of venom molecules. In Africa, geneticists are gathering DNA to probe the origin of our species. In clear, non-technical language, Zimmer explains the central concepts essential for understanding new advances in evolution, including natural selection, genetic drift, and sexual selection. He demonstrates how vital evolution is to all branches of modern biology—from the fight against deadly antibiotic-resistant bacteria to the analysis of the human genome. Richly illustrated with 285 illustrations and photographs, The Tangled Bank is essential reading for anyone who wants to understand the history of life on Earth.

    Contemplation of time and the discoveries of modern science lead to the assertion that the mind is paramount and limitless.

    As a pragmatic, hands-on guide for beginning to intermediate hobbyists, The Conscientious Marine Aquarist demystifies the process of planning, setting up, stocking, and managing a beautiful, thriving slice of the tropical ocean.

    But was it a savage sheep killer or a shy, fussy, nocturnal feeder? And did it really drink its victims' blood? Once reviled, feared and slaughtered by government decree, the myth of the Tasmanian Tiger continues to grow. So treasured is it now, the Tasmanian Tiger has become the official logo of the island that wiped it out and a symbol of the conservation movement world-wide.A number of Australian species have miraculously reappeared after being labelled as extinct. Perhaps the Tiger is still with us. And if it's not, can it be brought back by cloning?

    Today, more than sixty years later, members of a new generation of scientists are attempting to create life from the ground up. Science has moved forward in leaps and bounds since Schrodinger's time, but our understanding of what does and does not constitute life has only grown more complex. An era that has already seen computer chip-implanted human brains, genetically engineered organisms, genetically modified foods, cloned mammals, and brain-dead humans kept alive by machines is one that demands fresh thinking about the concept of life. While a segment of our national debate remains stubbornly mired in moral quandaries over abortion, euthanasia, and other right to life issues, the science writer Ed Regis demonstrates how science can and does provide us with a detailed understanding of the nature of life. Written in a lively and accessible style, and synthesizing a wide range of contemporary research, What Is Life? is a brief and illuminating contribution to an age-old debate.

    Sherwin Nuland, “a gifted and deeply intelligent writer” (San Francisco Chronicle), combines knowledge, compassion, and elegance of expression to shed light on the workings of our bodies from the perspective of a surgeon. Dr. Nuland recounts age-old legends about the functions and "personalities" of the body's organs and, in riveting vignettes of the surgery he has performed, he describes the connections between myth and reality. A brilliant blend of science and folklore, The Mysteries Within reveals the enigmas not only of the body but also of the human imagination.

    It's a great way to learn about nuclear physics!

    It sustainably provided enough food to allow cities, nations, and empires to grow, but it did so with a different emphasis. Where agriculture encouraged stability, fishing demanded movement. It frequently required a search for new and better fishing grounds; its technologies, centered on boats, facilitated movement and discovery; and fish themselves, when dried and salted, were the ideal food—lightweight, nutritious, and long-lasting—for traders, travelers, and conquering armies. This history of the long interaction of humans and seafood tours archaeological sites worldwide to show readers how fishing fed human settlement, rising social complexity, the development of cities, and ultimately the modern world.
