The only rock we eat, salt has shaped civilization from the very beginning, and its story is a glittering, often surprising part of the history of humankind. A substance so valuable it served as currency, salt has influenced the establishment of trade routes and cities, provoked and financed wars, secured empires, and inspired revolutions.

    Their first intimation of our existence might well be a Super Bowl broadcast or a stray transmission from the Playboy channel. But, of course, they might seem equally strange to us. How strange? Their senses could be entirely different from ours—they might see in the infrared or “hear” radio waves.What would aliens look like? An intelligent octopus-like creature is certainly plausible. What about odd numbers of limbs—a three-legged alien with three arms and three eyes? What about an entire planet of immobile, silicon-based “trees” that communicate with each other via electrical signals?The Science of Aliens gets weirder still. Could a giant interstellar cloud be “alive” and intelligent? Could creatures live at extremely high pressures and temperatures? And which of these many possibilities would be similar enough to us that they could communicate with them, or they with us? Would they have any interest in abducting us? Would they want to have sex with us?In classic Pickover style, here is speculation at the far edge of knowledge—and beyond.

    Suddenly, he suffered such bizarre medical symptoms, doctors suspected he'd been poisoned by the Mafia. Bell's rapidly declining health forced him to flee his glamorous Miami life to a sterile "bubble" unit in the remote Arizona desert. As his career and marriage dissolved, Bell pursued medical treatments in a race against time, hoping to stay alive and raise his young daughter. He eventually discovered he wasn’t poisoned by a criminal, but by his office building. His search for a cure led him to discover the horrifying truth: his plight was just the tip of the iceberg. Millions of people fall ill and die each year because of toxic chemical exposures—without knowing they're at risk.Bell chose to fight back. Despite his precarious health, he began collaborating with top scientists dedicated to raising awareness about this issue and finding treatments for victims. Meanwhile, his daughter miraculously found the one doctor who helped him. As Bell's health improved, he teamed up with other lawyers to avenge other victims in court.This riveting book puts a human face on the hidden truths behind toxic dangers assaulting us in our everyday environments—and offers practical ways to protect ourselves and our children.

    After World War II, it reshaped the global order-whoever could master uranium could master the world. Marie Curie gave us hope that uranium would be a miracle panacea, but the Manhattan Project gave us reason to believe that civilization would end with apocalypse. Slave labor camps in Africa and Eastern Europe were built around mine shafts and America would knowingly send more than six hundred uranium miners to their graves in the name of national security. Fortunes have been made from this yellow dirt; massive energy grids have been run from it. Fear of it panicked the American people into supporting a questionable war with Iraq and its specter threatens to create another conflict in Iran. Now, some are hoping it can help avoid a global warming catastrophe. In "Uranium," Tom Zoellner takes readers around the globe in this intriguing look at the mineral that can sustain life or destroy it.

    Their subjects include the components, function, and weight of the atmosphere; capillary attraction; the carbon content in oxygen and living bodies; respiration and its analogy to the burning of a candle; and much more. Numerous illustrations.

    Then, hours later, Flavia finds a man lying in the cucumber patch and watches him as he takes his dying breath.For Flavia, who is both appalled and delighted, life begins in earnest when murder comes to Buckshaw. “I wish I could say I was afraid, but I wasn’t. Quite the contrary. This was by far the most interesting thing that had ever happened to me in my entire life.”

    At first its discoverers mistook the readings for the disruption caused by the droppings of pigeons that had nested in their telescope, and yet they went on to win the Nobel prize. In the mid-1990s New Scientist writer Marcus Chown drove across America to interview the key scientists who had made this astonishing discovery. Their account and Chown's description of their achievement was published to much acclaim. But now, over a decade later, in this new and fully revised edition he goes behind the hype and the hysteria to provide a clear and lively explanation of one of the biggest discoveries in modern science - and a brilliant picture of what happened next.

    Welcome to laughing until it hurts while covered in bodily fluids. Welcome to simple math at very high stakes. Welcome to an incredibly inappropriate sense of humor. Welcome to serving people on the most stressful days of their lives. Welcome to putting your hands in places you never imagined they'd be. Welcome to your front row seat to the ballad of life and death. That's not the welcome that this nurse was looking for, but that's the one he got. Irreverent and audacious, this brutally honest memoir covers what it’s like to come of age in an American Hospital. Welcome to a rollicking peak behind the curtain to what medical providers, and the health care system, are truly like.

    Brenda Maddox tells a powerful story of a remarkably single-minded, forthright, and tempestuous young woman who, at the age of fifteen, decided she was going to be a scientist, but who was airbrushed out of the greatest scientific discovery of the twentieth century.

    With effervescent wit, Jones argues that men, biologically speaking, are the true second sex. Here he lays out the cases for and against masculinity -- exploring every biological aspect from the genesis of the Y chromosome onward -- based on the recent explosion of biological research. Along the way, he offers pithy commentary on topics such as male hormones, hair loss, and the hydraulics of man's most intimate organ. Fascinating and often surprising, Jones's evidence offers fresh fuel for the battle of the sexes.

    But molecules, such as water and sugar, are not alive. So how do our cells--assemblies of otherwise "dead" molecules--come to life, and together constitute a living being? In "Life's Ratchet," physicist Peter M. Hoffmann locates the answer to this age-old question at the nanoscale. The complex molecules of our cells can rightfully be called "molecular machines," or "nanobots"; these machines, unlike any other, work autonomously to create order out of chaos. Tiny electrical motors turn electrical voltage into motion, tiny factories custom-build other molecular machines, and mechanical machines twist, untwist, separate and package strands of DNA. The cell is like a city--an unfathomable, complex collection of molecular worker bees working together to create something greater than themselves. Life, Hoffman argues, emerges from the random motions of atoms filtered through the sophisticated structures of our evolved machinery. We are essentially giant assemblies of interacting nanoscale machines; machines more amazing than can be found in any science fiction novel. Incredibly, the molecular machines in our cells function without a mysterious "life force," nor do they violate any natural laws. Scientists can now prove that life is not supernatural, and that it can be fully understood in the context of science. Part history, part cutting-edge science, part philosophy, "Life's Ratchet" takes us from ancient Greece to the laboratories of modern nanotechnology to tell the story of our quest for the machinery of life.
