    There is every reason to believe that, within a few weeks of its onset, the infection was universally present in the nose and throat of the people, disseminated by mouth spray given off on talking by innumerable carriers and, in addition, by the coughing and sneezing of the sick. Susceptibility was very general, though it varied greatly in degree. Among those who escaped well marked sickness there are few who could not recall having had an occluded or running nose, or a raw feeling in the throat, or a cough, or aches and pains, at some time during the period of the prevalence of the disease, these probably representing the price such persons paid for their immunization." - Dr. Bernard Fantus In many ways, it is hard for modern people living in First World countries to conceive of a pandemic sweeping around the world and killing millions of people, and it is even harder to believe that something as common as influenza could cause such widespread illness and death. Although the flu still takes hundreds of lives each year, most of those lost are very young or old or ill with something else that had already weakened them. In fact, most people contract influenza at least once, and many suffer from the flu several times in their lives and survive it with a minimum amount of medical attention. In 1918, the world was still in the throes of the Great War, the deadliest conflict in human history at that point, but while World War I would be a catastrophic war surpassed only by World War II, an unprecedented influenza outbreak that same year inflicted casualties that would make both wars pale in comparison. An illness, or more likely a collection of illnesses, Spanish influenza quickly spread across the world and may have killed upwards of 100 million people, decimating populations across developed nations and possibly wiping out as much as 5% of the world’s population. If anything, the ongoing war and the censorship maintained by the countries fighting it may have resulted in the actual toll of the outbreak being underestimated based on the way soldiers’ deaths were categorized. World War I may have distracted people about the unprecedented nature of the outbreak, but the most alarming aspect of the outbreak in 1918 was the indiscriminate nature in which the scourge attacked young and old, healthy and unhealthy, and rich and poor alike. In fact, the popular name for the outbreak was a reference to the fact that Spain’s own king was stricken with the disease. While he and President Woodrow Wilson ended up surviving it, former First Lady Rose Cleveland did not. The staggering number of fatalities, and the way in which seemingly anybody could suffer during the outbreak, taught people in the early 20th century that regardless of the tremendous strides made by technology, and no matter how stalemated the war was, nobody was safe from nature itself. Of course, it also demonstrated how much more work could be done to prevent similar occurrences. The 1918 pandemic was neither the first nor the last outbreak of the flu, but it was by far the worst, and it forever changed the face of medicine and public health care in both North America and Europe. The 1918 Spanish Flu Pandemic: The History and Legacy of the World’s Deadliest Outbreak chronicles the devastating disease and the damage it wrought across the globe.

    On the cusp of decoding brain signals that govern motor skills, they are developing miraculous technologies to enable paraplegics and wounded soldiers to move prosthetic limbs, and the rest of us to manipulate computers and other objects through thought alone. These fiercely competitive scientists are vying for Defense Department and venture capital funding, prestige, and great wealth. Part life-altering cure, part science fiction, part military dream, these cutting-edge brain-computer interfaces promise to improve lives—but also hold the potential to augment soldiers' combat capabilities. In The Brain Electric, Malcolm Gay follows the dramatic emergence of these technologies, taking us behind the scenes into the operating rooms, start-ups, and research labs where the future is unfolding. With access to many of the field's top scientists, Gay illuminates this extraordinary race—where science, medicine, profit, and war converge—for the first time. But this isn't just a story about technology. At the heart of this research is a group of brave, vulnerable patient-volunteers whose lives are given new meaning through participating in these experiments. The Brain Electric asks us to rethink our relationship to technology, our bodies, even consciousness itself—challenging our assumptions about what it means to be human.

    Just a half century ago, this idea was revolutionary. In April 1953, James Watson and Francis Crick published in Nature their groundbreaking work revealing the double helix structure of DNA. While this discovery received wide attention from both mainstream media and the academic community, it was just one part of the bigger story in this history of molecular biology. By the mid-1950s, the scientific community confirmed that genes were indeed comprised of DNA; they just needed to crack the genetic code—and the race was on. Life’s Greatest Secret is the full and rich history of this challenge and the characters—many of whom were not biologists—whose work contributed to this grand scientific endeavor: mathematician and father of cybernetics Norbert Wiener, physicist Erwin Schrödinger, information theorist Claude Shannon, and biologists Jacques Monod and Marshall Nirenberg.In Life’s Greatest Secret, science historian and zoologist Matthew Cobb shows that the race to crack the genetic code was mostly a matter of craft—individuals or small groups struggling with ideas and concepts as much as they were with facts, trying to find the right experiment to answer the right questions, even if they didn’t know what the questions were, and finding that, even when the most definitive answer served mostly to reveal more ignorance, whether in 1953, with Watson and Crick, or in 1961, when Nirenberg and Matthaei showed how DNA codes for specific amino acids, and again and again thereafter, or in 2000, with the first publication of a human genome. Each discovery was a leap forward in our understanding of the natural world and our place within in, akin to the discoveries of Galileo and Einstein in the realm of physics, or the publication of Darwin’s On the Origin of Species. And each served to show how much bigger the problem was that anyone had previously imagined, a trend that continues, as Cobb shows, even today, whether we are discussing gene regulation, epigenetics, or GMOs.Life’s Greatest Secret is a story of ideas and of experimentation, of ingenuity, insight, and dead-ends, in the hunt to make the greatest discovery of twentieth century biology. Ultimately, though, this is a story of humans exploring what it is that makes us human.

    To understand the universe in the far future, we must first describe its present state and structure on the grand scale, and how its present properties arose. Dr Islam explains these topics in an accessible way in the first part of the book. From this background he speculates about the future evolution of the universe and predicts the major changes that will occur. The author has largely avoided mathematical formalism and therefore the book is well suited to general readers with a modest background knowledge of physics and astronomy.

    This exciting body-mind approach to personality has a liberating and positive effect on emotional, physical, and psychic distress. Dr. Alexander Lowen, founder and prime mover of this fast-growing therapy, writes that increased joy and pleasure are possible in every day life through an understanding of how your body functions energetically: how it determines what you feel, think, and do. Dr. Lowen points out that lack of energy is the result of chronic muscular tensions, a condition caused by the suppression of feelings. These tensions can be dissolved through the direct body work in bioenergetic exercise, which restores the potential for living a rich, full life. Dr. Lowen analyzes common physical ailments like headaches and lower back pain and shows how they too can be overcome by releasing the muscular tenstion that create them. Generously illustrated with line drawings of bioenergetic exercises, this book is sure to bring freedom, confidence, and pleasure to thousands of men and women.In this highly interesting and valuable attempt to restore the body to the mind, Dr. Alexander Lowen sets out in a practically useful way the principles of his new form of psychotherapy. Bioenergetics is destined to become widely influential. --Ashley Montagu
