What links conscious experience of pain, joy, color, and smell to bioelectrical activity in the brain? How can anything physical give rise to nonphysical, subjective, conscious states? Christof Koch has devoted much of his career to bridging the seemingly unbridgeable gap between the physics of the brain and phenomenal experience. Consciousness: Confessions of a Romantic Reductionist --part scientific overview, part memoir, part futurist speculation--describes Koch's search for an empirical explanation for consciousness. Koch recounts not only the birth of the modern science of consciousness but also the subterranean motivation for his quest--his instinctual (if "romantic") belief that life is meaningful.Koch describes his own groundbreaking work with Francis Crick in the 1990s and 2000s and the gradual emergence of consciousness (once considered a "fringy" subject) as a legitimate topic for scientific investigation. Present at this paradigm shift were Koch and a handful of colleagues, including Ned Block, David Chalmers, Stanislas Dehaene, Giulio Tononi, Wolf Singer, and others. Aiding and abetting it were new techniques to listen in on the activity of individual nerve cells, clinical studies, and brain-imaging technologies that allowed safe and noninvasive study of the human brain in action.Koch gives us stories from the front lines of modern research into the neurobiology of consciousness as well as his own reflections on a variety of topics, including the distinction between attention and awareness, the unconscious, how neurons respond to Homer Simpson, the physics and biology of free will, dogs, Der Ring des Nibelungen, sentient machines, the loss of his belief in a personal God, and sadness. All of them are signposts in the pursuit of his life's work--to uncover the roots of consciousness.Christof Koch is Professor of Biology and of Engineering at the California Institute of Technology and Chief Scientific Officer of the Allen Institute for Brain Science in Seattle. He is the author of The Quest for Consciousness and other books.

Like it or not, knowing how to make use of online tools without being overloaded with too much information is an essential ingredient to personal success in the twenty-first century. But how can we use digital media so that they make us empowered participants rather than passive receivers, grounded, well-rounded people rather than multitasking basket cases? In Net Smart, cyberculture expert Howard Rheingold shows us how to use social media intelligently, humanely, and, above all, mindfully.Mindful use of digital media means thinking about what we are doing, cultivating an ongoing inner inquiry into how we want to spend our time. Rheingold outlines five fundamental digital literacies, online skills that will help us do this: attention, participation, collaboration, critical consumption of information (or "crap detection"), and network smarts. He explains how attention works, and how we can use our attention to focus on the tiny relevant portion of the incoming tsunami of information. He describes the quality of participation that empowers the best of the bloggers, netizens, tweeters, and other online community participants; he examines how successful online collaborative enterprises contribute new knowledge to the world in new ways; and he teaches us a lesson on networks and network building.Rheingold points out that there is a bigger social issue at work in digital literacy, one that goes beyond personal empowerment. If we combine our individual efforts wisely, it could produce a more thoughtful society: countless small acts like publishing a Web page or sharing a link could add up to a public good that enriches everybody.Howard Rheingold, an influential writer and thinker on social media, is the author ofTools for Thought: The History and Future of Mind-Expanding Technology, The Virtual Community: Homesteading on the Electronic Frontier (both published by the MIT Press), and Smart Mobs: The Next Social Revolution.

Long ago, in 1985, personal computers came in two general categories: the friendly, childish game machine used for fun (exemplified by Atari and Commodore products); and the boring, beige adult box used for business (exemplified by products from IBM). The game machines became fascinating technical and artistic platforms that were of limited real-world utility. The IBM products were all utility, with little emphasis on aesthetics and no emphasis on fun. Into this bifurcated computing environment came the Commodore Amiga 1000. This personal computer featured a palette of 4,096 colors, unprecedented animation capabilities, four-channel stereo sound, the capacity to run multiple applications simultaneously, a graphical user interface, and powerful processing potential. It was, Jimmy Maher writes in The Future Was Here, the world's first true multimedia personal computer.Maher argues that the Amiga's capacity to store and display color photographs, manipulate video (giving amateurs access to professional tools), and use recordings of real-world sound were the seeds of the digital media future: digital cameras, Photoshop, MP3 players, and even YouTube, Flickr, and the blogosphere. He examines different facets of the platform--from Deluxe Paint to AmigaOS to Cinemaware--in each chapter, creating a portrait of the platform and the communities of practice that surrounded it. Of course, Maher acknowledges, the Amiga was not perfect: the DOS component of the operating systems was clunky and ill-matched, for example, and crashes often accompanied multitasking attempts. And Commodore went bankrupt in 1994. But for a few years, the Amiga's technical qualities were harnessed by engineers, programmers, artists, and others to push back boundaries and transform the culture of computing.Jimmy Maher is an independent scholar and writer living in Norway.

Daily life is connected life, its rhythms driven by endless email pings and responses, the chimes and beeps of continually arriving text messages, tweets and retweets, Facebook updates, pictures and videos to post and discuss. Our perpetual connectedness gives us endless opportunities to be part of the give-and-take of networking.Some worry that this new environment makes us isolated and lonely. But in Networked, Lee Rainie and Barry Wellman show how the large, loosely knit social circles of networked individuals expand opportunities for learning, problem solving, decision making, and personal interaction. The new social operating system of “networked individualism” liberates us from the restrictions of tightly knit groups; it also requires us to develop networking skills and strategies, work on maintaining ties, and balance multiple overlapping networks.Rainie and Wellman outline the “triple revolution” that has brought on this transformation: the rise of social networking, the capacity of the Internet to empower individuals, and the always-on connectivity of mobile devices. Drawing on extensive evidence, they examine how the move to networked individualism has expanded personal relationships beyond households and neighborhoods; transformed work into less hierarchical, more team-driven enterprises; encouraged individuals to create and share content; and changed the way people obtain information. Rainie and Wellman guide us through the challenges and opportunities of living in the evolving world of networked individuals.Lee Rainie is Director of the Pew Research Center’s Internet & American Life Project and former managing editor of U.S. News and World Report.

In Infectious Behavior, neurobiologist Paul Patterson examines the involvement of the immune system in autism, schizophrenia, and major depressive disorder. Although genetic approaches to these diseases have garnered the lion's share of publicity and funding, scientists are uncovering evidence of the important avenues of communication between the brain and the immune system and their involvement in mental illness. Patterson focuses on this brain-immune crosstalk, exploring the possibility that it may help us understand the causes of these common, but still mysterious, diseases. The heart of this engaging book, accessible to nonscientists, concerns the involvement of the immune systems of the pregnant woman and her fetus, and a consideration of maternal infection as a risk factor for schizophrenia and autism. Patterson reports on research that may shed light on today's autism epidemic. He also outlines the risks and benefits of both maternal and postnatal vaccinations.In the course of his discussion, Patterson offers a short history of immune manipulation in treating mental illness (recounting some frightening but fascinating early experiments) and explains how the immune system influences behavior and how the brain regulates the immune system, looking in particular at stress and depression. He examines the prenatal origins of adult disease and evidence for immune involvement in autism, schizophrenia, and depression. Finally, he describes the promise shown by recent animal experiments that have led to early clinical trials of postnatal and adult treatments for patients with autism and related disorders.Paul H. Patterson, a developmental neurobiologist, is Anne P. and Benjamin R. Biaggini Professor of Biological Sciences at the California Institute of Technology and a Research Professor of Neurological Surgery at the University of Southern California’s Keck School of Medicine. He is the coauthor (with Alan Brown) of The Origins of Schizophrenia.

We live today in a global web of interdependence, connected technologically, economically, politically, and socially. As a result of these expanding and deepening interdependencies, it has become impossible fully to control--or foretell--the effects of our actions. The world is rife with unintended consequences. The first law of human ecology--which declares that we can never do merely one thing--is a truth we ignore at our peril. In Indra's Net and the Midas Touch, Leslie Paul Thiele explores the impact of interdependence and unintended consequences on our pursuit of sustainability.Unfortunately, good intentions provide no antidote to the law of unintended consequences, and proffered cures often prove worse than the disease. Biofuels developed for the purpose of reducing carbon emissions, for example, have had the unintended effect of cutting off food supplies to the needy and destroying rain forests. We must fundamentally transform our patterns of thinking and behavior. Thiele offers the intellectual and moral foundations for this transformation, drawing from ecology, ethics, technology, economics, politics, psychology, physics, and metaphysics. Awareness of our interconnectedness, he writes, stimulates creativity and community; it is a profound responsibility and a blessing beyond measure.Leslie Paul Thiele is Professor in the Department of Political Science and the Director of Sustainability Studies at the University of Florida.

Hello Avatar Or, {llSay(0, Hello, Avatar ); is a tiny piece of user-friendly code that allows us to program our virtual selves. In Hello Avatar, B. Coleman examines a crucial aspect of our cultural shift from analog to digital: the continuum between online and off-, what she calls the "x-reality" that crosses between the virtual and the real. She looks at the emergence of a world that is neither virtual nor real but encompasses a multiplicity of network combinations. And she argues that it is the role of the avatar to help us express our new agency--our new power to customize our networked life.By avatar, Coleman means not just the animated figures that populate our screens but the gestalt of images, text, and multimedia that make up our online identities--in virtual worlds like Second Life and in the form of email, video chat, and other digital artifacts. Exploring such network activities as embodiment, extreme (virtual) violence, and the work in virtual reality labs, and offering sidebar interviews with designers and practitioners, she argues that what is new is real-time collaboration and copresence, the way we make connections using networked media and the cultures we have created around this. The star of this drama of expanded horizons is the networked subject--all of us who represent aspects of ourselves and our work across the mediascape.B. Coleman is Assistant Professor of Writing and New Media in MIT’s Program in Writing and Humanistic Studies and Comparative Media Studies. She is Faculty Director of the C3 Game Culture and Mobile Media initiative.

America's once-vibrant small-to-midsize cities--Syracuse, Worcester, Akron, Flint, Rockford, and others--increasingly resemble urban wastelands. Gutted by deindustrialization, outsourcing, and middle-class flight, disproportionately devastated by metro freeway systems that laid waste to the urban fabric and displaced the working poor, small industrial cities seem to be part of America's past, not its future. And yet, Catherine Tumber argues in this provocative book, America's gritty Rust Belt cities could play a central role in a greener, low-carbon, relocalized future.As we wean ourselves from fossil fuels and realize the environmental costs of suburban sprawl, we will see that small cities offer many assets for sustainable living not shared by their big city or small town counterparts, including population density and nearby, fertile farmland available for new environmentally friendly uses.Tumber traveled to twenty-five cities in the Northeast and Midwest--from Buffalo to Peoria to Detroit to Rochester--interviewing planners, city officials, and activists, and weaving their stories into this exploration of small-scale urbanism. Smaller cities can be a critical part of a sustainable future and a productive green economy. Small, Gritty, and Green will help us develop the moral and political imagination we need to realize this.Catherine Tumber, a journalist and historian, is the author of American Feminism and the Birth of New Age Spirituality: Searching for the Higher Self, 1875–1915.

We will not find “exposure to burning coal” listed as the cause of death on a single death certificate, but tens of thousands of deaths from asthma, chronic obstructive pulmonary disease, lung cancer, heart attacks, strokes, and other illnesses are clearly linked to coal-derived pollution. As politicians and advertising campaigns extol the virtues of “clean coal,” the dirty secret is that coal kills. In The Silent Epidemic, Alan Lockwood, a physician, describes and documents the adverse health effects of burning coal. Lockwood's comprehensive treatment examines every aspect of coal, from its complex chemical makeup to details of mining, transporting, burning, and disposal—each of which generates significant health concerns. He describes coal pollution's effects on the respiratory, cardiovascular, and nervous systems, and how these problems will only get worse; explains the impact of global warming on coal-related health problems; and discusses possible policy approaches to combat coal pollution.Coal fueled the industrial revolution and has become a major source of energy in virtually every country. In the United States, almost half of the energy used to generate electricity comes from burning coal. Relatively few people are aware of the health threats posed by coal-derived pollutants, and those who are aware lack the political clout of the coal industry. Lockwood's straightforward description of coal as a health hazard is especially timely, given the barrage of marketing efforts to promote coal as part of “energy independence.” His message is clear and urgent: “Coal-fired plants make people sick and die, particularly children and those with chronic illnesses, and they cost society huge amounts of money desperately needed for other purposes.”Alan H. Lockwood, M.D. is Emeritus Professor of Neurology and Nuclear Medicine at the State University of New York at Buffalo. He is the lead author of a Physicians for Social Responsibility report on coal’s adverse health effects.

Geologists in the field climb hills and hang onto craggy outcrops; they put their fingers in sand and scratch, smell, and even taste rocks. Beginning in 2004, however, a team of geologists and other planetary scientists did field science in a dark room in Pasadena, exploring Mars from NASA's Jet Propulsion Laboratory (JPL) by means of the remotely operated Mars Exploration Rovers (MER). Clustered around monitors, living on Mars time, painstakingly plotting each movement of the rovers and their tools, sensors, and cameras, these scientists reported that they felt as if they were on Mars themselves, doing field science. The MER created a virtual experience of being on Mars. In Working on Mars, William Clancey examines how the MER has changed the nature of planetary field science.Drawing on his extensive observations of scientists in the field and at the JPL, Clancey investigates how the design of the rover mission enables field science on Mars, explaining how the scientists and rover engineers manipulate the vehicle and why the programmable tools and analytic instruments work so well for them. He shows how the scientists felt not as if they were issuing commands to a machine but rather as if they were working on the red planet, riding together in the rover on a voyage of discovery.William J. Clancey is Chief Scientist of Human-Centered Computing in the Intelligent Systems Division at NASA Ames Research Center, and Senior Research Scientist at the Florida Institute for Human and Machine Cognition.
