FROM THE BOOK:"I want to touch you and kiss you.""You are my mother's sister and only one year older; you must have something of my mother in you."—A found child after being returned to her family Searching for Life traces the courageous plight of the Grandmothers of the Plaza de Mayo, a group of women who challenged the ruthless dictatorship that ruled Argentina from 1976 to 1983. Acting as both detectives and human rights advocates in an effort to find and recover their grandchildren, the Grandmothers identified fifty-seven of an estimated 500 children who had been kidnapped or born in detention centers. The Grandmothers' work also led to the creation of the National Genetic Data Bank, the only bank of its kind in the world, and to Article 8 of the United Nations Convention on the Rights of the Child, the "right to identity," that is now incorporated in the new adoption legislation in Argentina. Rita Arditti has conducted extensive interviews with twenty Grandmothers and twenty-five others connected with their work; her book is a testament to the courage, persistence, and strength of these "traditional" older women. The importance of the Grandmothers' work has effectively transcended the Argentine situation. Their tenacious pursuit of justice defies the culture of impunity and the historical amnesia that pervades Argentina and much of the rest of the world today. In addition to reconciling the "living disappeared" with their families of origin, these Grandmothers restored a chapter of history that, too, had been abducted and concealed from its rightful heirs.

Inside the epic quest to find life on the water-rich moons at the outer reaches of the solar system Where is the best place to find life beyond Earth? We often look to Mars as the most promising site in our solar system, but recent scientific missions have revealed that some of the most habitable real estate may actually lie farther away. Beneath the frozen crusts of several of the small, ice-covered moons of Jupiter and Saturn lurk vast oceans that may have existed for as long as Earth, and together may contain more than fifty times its total volume of liquid water. Could there be organisms living in their depths? Alien Oceans reveals the science behind the thrilling quest to find out. Kevin Peter Hand is one of today's leading NASA scientists, and his pioneering research has taken him on expeditions around the world. In this captivating account of scientific discovery, he brings together insights from planetary science, biology, and the adventures of scientists like himself to explain how we know that oceans exist within moons of the outer solar system, like Europa, Titan, and Enceladus. He shows how the exploration of Earth's oceans is informing our understanding of the potential habitability of these icy moons, and draws lessons from what we have learned about the origins of life on our own planet to consider how life could arise on these distant worlds. Alien Oceans describes what lies ahead in our search for life in our solar system and beyond, setting the stage for the transformative discoveries that may await us.

We enter life with nothing, without clothing, unable to speak, defenseless in an unknown world. How can we have a purpose & meaning in life at this time? But, what did we arrive with? We arrived with everything needed to survive in the world! All we need now is someone's Inner Spirit of love to take care of the body and instruct us on finding purpose of life, but how do our mentors know what our purpose of life is? No one, but you will know your purpose. Some never know, others search their entire life without finding their purpose, yet others find it right away, while some not until later in life. So; how will you known when you find purpose & meaning in your life? You search for it! The writer will be your guide in this search and provide key informational research, writings, websites, to answer questions, but it will be up to you, the reader to determine the answers.

Astrobiology is the study of the origin, evolution, distribution, and future of life in the universe. It is an inherently interdisciplinary field that encompasses astronomy, biology, geology, heliophysics, and planetary science, including complementary laboratory activities and field studies conducted in a wide range of terrestrial environments. Combining inherent scientific interest and public appeal, the search for life in the solar system and beyond provides a scientific rationale for many current and future activities carried out by the National Aeronautics and Science Administration (NASA) and other national and international agencies and organizations. Requested by NASA, this study offers a science strategy for astrobiology that outlines key scientific questions, identifies the most promising research in the field, and indicates the extent to which the mission priorities in existing decadal surveys address the search for life's origin, evolution, distribution, and future in the universe. This report makes recommendations for advancing the research, obtaining the measurements, and realizing NASA's goal to search for signs of life in the universe.

“Weird indeed, and not a little wonderful.”—Nature In the 1980s and 1990s, in places where no one thought it possible, scientists found organisms they called extremophiles: lovers of extremes. There were bacteria in volcanic hydrothermal vents on the ocean floor, single-celled algae in Antarctic ice floes, and fungi in the cooling pools of nuclear reactors. But might there be life stranger than the most extreme extremophile? Might there be, somewhere, another kind of life entirely? In fact, scientists have hypothesized life that uses ammonia instead of water, life based not in carbon but in silicon, life driven by nuclear chemistry, and life whose very atoms are unlike those in life we know. In recent years some scientists have begun to look for the tamer versions of such life on rock surfaces in the American Southwest, in a “shadow biosphere” that might impinge on the known biosphere, and even deep within human tissue. They have also hypothesized more radical versions that might survive in Martian permafrost, in the cold ethylene lakes on Saturn’s moon Titan, and in the hydrogen-rich atmospheres of giant planets in other solar systems. And they have imagined it in places off those worlds: the exotic ices in comets, the vast spaces between the stars, and—strangest of all—parallel universes. Distilling complex science in clear and lively prose, David Toomey illuminates the research of the biological avant-garde and describes the workings of weird organisms in riveting detail. His chapters feature an unforgettable cast of brilliant scientists and cover everything from problems with our definitions of life to the possibility of intelligent weird life. With wit and understanding that will delight scientists and lay readers alike, Toomey reveals how our current knowledge of life forms may account for only a tiny fraction of what’s really out there.
