Addressing a field that has been dominated by astronomers, physicists, engineers, and computer scientists, the contributors to this collection raise questions that may have been overlooked by physical scientists about the ease of establishing meaningful communication with an extraterrestrial intelligence. These scholars are grappling with some of the enormous challenges that will face humanity if an information-rich signal emanating from another world is detected. By drawing on issues at the core of contemporary archaeology and anthropology, we can be much better prepared for contact with an extraterrestrial civilization, should that day ever come.

On January 20, 1942, black oil mill worker Cleo Wright assaulted a white woman in her home and nearly killed the first police officer who tried to arrest him. An angry mob then hauled Wright out of jail and dragged him through the streets of Sikeston, Missouri, before burning him alive. Wright's death was, unfortunately, not unique in American history, but what his death meant in the larger context of life in the United States in the twentieth-century is an important and compelling story. After the lynching, the U.S. Justice Department was forced to become involved in civil rights concerns for the first time, provoking a national reaction to violence on the home front at a time when the country was battling for democracy in Europe. Dominic Capeci unravels the tragic story of Wright's life on several stages, showing how these acts of violence were indicative not only of racial tension but the clash of the traditional and the modern brought about by the war. Capeci draws from a wide range of archival sources and personal interviews with the participants and spectators to draw vivid portraits of Wright, his victims, law-enforcement officials, and members of the lynch mob. He places Wright in the larger context of southern racial violence and shows the significance of his death in local, state, and national history during the most important crisis of the twentieth-century.

In 1953, 27-year-old Henry Gustave Molaison underwent an experimental "psychosurgical" procedure -- a targeted lobotomy -- in an effort to alleviate his debilitating epilepsy. The outcome was unexpected -- when Henry awoke, he could no longer form new memories, and for the rest of his life would be trapped in the moment. But Henry's tragedy would prove a gift to humanity. As renowned neuroscientist Suzanne Corkin explains in Permanent Present Tense, she and her colleagues brought to light the sharp contrast between Henry's crippling memory impairment and his preserved intellect. This new insight that the capacity for remembering is housed in a specific brain area revolutionized the science of memory. The case of Henry -- known only by his initials H. M. until his death in 2008 -- stands as one of the most consequential and widely referenced in the spiraling field of neuroscience. Corkin and her collaborators worked closely with Henry for nearly fifty years, and in Permanent Present Tense she tells the incredible story of the life and legacy of this intelligent, quiet, and remarkably good-humored man. Henry never remembered Corkin from one meeting to the next and had only a dim conception of the importance of the work they were doing together, yet he was consistently happy to see her and always willing to participate in her research. His case afforded untold advances in the study of memory, including the discovery that even profound amnesia spares some kinds of learning, and that different memory processes are localized to separate circuits in the human brain. Henry taught us that learning can occur without conscious awareness, that short-term and long-term memory are distinct capacities, and that the effects of aging-related disease are detectable in an already damaged brain. Undergirded by rich details about the functions of the human brain, Permanent Present Tense pulls back the curtain on the man whose misfortune propelled a half-century of exciting research. With great clarity, sensitivity, and grace, Corkin brings readers to the cutting edge of neuroscience in this deeply felt elegy for her patient and friend.
