Instead, ants decide what to do based on the rate, rhythm, and pattern of individual encounters and interactions--resulting in a dynamic network that coordinates the functions of the colony. Ant Encounters provides a revealing and accessible look into ant behavior from this complex systems perspective.Focusing on the moment-to-moment behavior of ant colonies, Deborah Gordon investigates the role of interaction networks in regulating colony behavior and relations among ant colonies. She shows how ant behavior within and between colonies arises from local interactions of individuals, and how interaction networks develop as a colony grows older and larger. The more rapidly ants react to their encounters, the more sensitively the entire colony responds to changing conditions. Gordon explores whether such reactive networks help a colony to survive and reproduce, how natural selection shapes colony networks, and how these structures compare to other analogous complex systems. Ant Encounters sheds light on the organizational behavior, ecology, and evolution of these diverse and ubiquitous social insects.

    The word conjures up images of horrific diseases sweeping the globe and killing everyone in their path. But such highly lethal illnesses almost never create pandemics. The reality is deadly serious but far more subtle.In Pandemics: What Everyone Needs to Know�, Peter Doherty, who won the Nobel Prize for his work on how the immune system recognizes virus-infected cells, offers an essential guide to one of the truly life-or-death issues of our age. In concise, question-and-answer format, he explains the causes of pandemics, how they can be counteracted with vaccines and drugs, and how we can better prepare for them in the future. Doherty notes that the term "pandemic" refers not to a disease's severity but to its ability to spread rapidly over a wide geographical area. Extremely lethal pathogens are usually quickly identified and confined. Nevertheless, the rise of high-speed transportation networks and the globalization of trade and travel have radically accelerated the spread of diseases. A traveler from Africa arrived in New York in 1999 carrying the West Nile virus; one mosquito bite later, it was loose in the ecosystem. Doherty explains how the main threat of a pandemic comes from respiratory viruses, such as influenza and SARS, which disseminate with incredible speed through air travel. The climate disruptions of global warming, rising population density, and growing antibiotic resistance all complicate efforts to control pandemics. But Doherty stresses that pandemics can be fought effectively. Often simple health practices, especially in hospitals, can help enormously. And research into the animal reservoirs of pathogens, from SARS in bats to HIV in chimpanzees, show promise for our prevention efforts.Calm, clear, and authoritative, Peter Doherty's Pandemics is one of the most critically important additions to the What Everyone Needs to Know� series.What Everyone Needs to Know� is a registered trademark of Oxford University Press.

    Lying in the eastern Pacific Ocean, straddling the equator off the west coast of South America, the Galágos is the most pristine archipelago to be found anywhere in the tropics. It is so remote, so untouched, that the act of wading ashore can make you feel like you are the first to do so. Yet the Galágos is far more than a wild paradise on earth-it is one of the most important sites in the history of science. Home to over 4,000 species native to its shores, around 40 percent of them endemic, the islands have often been called a "laboratory of evolution." The finches collected on the Galágos inspired Darwin's revolutionary theory of natural selection. In The Galágos, science writer Henry Nicholls offers a lively natural and human history of the archipelago, charting its course from deserted wilderness to biological testing ground and global ecotourism hot spot. Describing the island chain's fiery geological origins as well as our species' long history of interaction with the islands, he draws vivid portraits of the life forms found in the Galágos, capturing its awe-inspiring landscapes, understated flora, and stunning wildlife. Nicholls also reveals the immense challenges facing the islands, which must continually balance conservation and ever encroaching development. Beautifully weaving together natural history, evolutionary theory, and his own experience on the islands, Nicholls shows that the story of the Galágos is not merely an isolated concern, but reflects the future of our species' relationship with nature-and the fate of our planet.

    Being Mortal by Atul Gawande - A 20-minute Summary Inside this Instaread Summary: • Overview of the entire book• Introduction to the important people in the book• Summary and analysis of all the chapters in the book• Key Takeaways of the book• A Reader's Perspective Preview of this summary: Chapter 1 Gawande grew up in Ohio. His parents were immigrants from India and both were doctors. His grandparents stayed in India, and there were few older people in his neighborhood, so he had little experience with aging or death until he met his wife’s grandmother, Alice Hobson. Hobson was seventy-seven and living on her own in Virginia. She was a spirited widow who fixed her own plumbing and volunteered with Meals On Wheels. However, Hobson was losing strength and height steadily each year as her arthritis worsened.Gawande’s father enthusiastically adopted the customs of his new country, but he could not understand the way in which seniors were treated in the US. In India, the elderly were treated with great respect and lived out their lives with family.In the United States, Sitaram Gawande, Gawande’s grandfather, likely would have been sent to a nursing home like most of the elderly who cannot handle the basics of daily living by themselves. However, in India, Sitaram Gawande was able to live in his own home and manage his own affairs, with family constantly around him. He died at the age of one hundred and ten when he fell off a bus during a business trip.Until recently, most elderly people stayed with their families. Even as the nuclear family unit became predominant, replacing the multi-generational family unit, people cared for their elderly relatives. Families were large and one child, usually a daughter, would not marry in order to take care of the parents.This has changed in much of the world, where elderly people end up struggling to live alone, like Hobson, rather than living with dignity amid family, like Sitaram Gawande.One cause of this change can be found in the nature of knowledge. When few people lived to be very old, elders were honored. Their store of knowledge was greatly useful. People often portrayed themselves as older to command respect. Modern society’s emphasis on youth is a complete reversal of this attitude. Technological advances are perceived as the territory of the young, and everyone wants to be younger. High-tech job opportunities are all over the world, and young people do not hesitate to leave their parents behind to pursue them.In developed countries, parents embrace the concept of a retirement filled with leisure activities. Parents are happy to begin living for themselves once children are grown. However, this system only works for young, healthy retirees, but not for those who cannot continue to be independent. Hobson, for example, was falling frequently and suffering memory lapses. Her doctor did tests and wrote prescriptions, but did not know what to do about her deteriorating condition. Neither did her family… About the Author With Instaread Summaries, you can get the summary of a book in 30 minutes or less. We read every chapter, summarize and analyze it for your convenience.

    The culprit--so necessary and yet the source of such upheaval--is the X chromosome, and this is its story. An enlightening and entertaining tour of the cultural and natural history of this intriguing member of the genome, "The X in Sex" traces the journey toward our current understanding of the nature of X. From its chance discovery in the nineteenth century to the promise and implications of ongoing research, David Bainbridge shows how the X evolved and where it and its counterpart Y are going, how it helps assign developing human babies their sex--and maybe even their sexuality--and how it affects our lives in infinitely complex and subtle ways. X offers cures for disease, challenges our cultural, ethical, and scientific assumptions about maleness and femaleness, and has even reshaped our views of human evolution and human nature.
