His historic career as an aviator made Charles Lindbergh one of the most famous men of the twentieth century, the subject of best-selling biographies and a hit movie, as well as the inspiration for a dance step the Lindy Hop that he himself was too shy to try. But for all the attention lavished on Lindbergh, one story has remained untold until now: his macabre scientific collaboration with Dr. Alexis Carrel. This oddest of couples one a brilliant Nobel Prize-winning surgeon turned social engineer, the other a failed dirt farmer turned hero of the skies joined forces in 1930 driven by a shared and secret dream: to conquer death and attain immortality. Part Frankenstein, part The Professor and the Madman, and all true, The Immortalists is the remarkable story of how two men of prodigious achievement and equally large character flaws challenged nature's oldest rule, with consequences personal, professional, and political that neither man anticipated.

In the tradition of the acclaimed graphic memoirs Fun Home and Persepolis comes a funny, insightful, and deeply moving book about learning to appreciate what we have when we can't seem to get what we want. For Phoebe Potts, the path to maternal fulfillment has not been easy. All her friends seem to get pregnant, but she can't conceive for all her trying. As Phoebe and her husband, Jeff, navigate the emotionally and physically fraught world of fertility experts, she takes stock of what matters in the rest of her life and reflects on the winding journey to her true calling as an artist. From her days as an amateur union organizer in Texas to her spiral into paralyzing depression in Mexico; from her soul-shrinking, all-for-the-benefits stint as an administrative assistant at a fancy university in Cambridge to her flirtation with rabbinical school, Phoebe illuminates the bumpy road to vocational and personal contentment. Her wonderful, hilarious, and utterly original drawings capture the truly good eggs an unforgettably nutty mother; a devoted husband; a team of therapists, hairdressers, and landladies; friends; and a sidekick housecat that together expand the definition of what really makes a family.

Before long, and without intending it, I found that jewelry had become part of my personal diplomatic arsenal. Former president George H. W. Bush had been known for saying "Read my lips." I began urging colleagues and reporters to "Read my pins." It would never have happened if not for Saddam Hussein. When U.S. ambassador to the United Nations Madeleine Albright criticized the dictator, his poet in residence responded by calling her "an unparalleled serpent." Shortly thereafter, while preparing to meet with Iraqi officials, Albright pondered: What to wearShe decided to make a diplomatic statement by choosing a snake pin. Although her method of communication was new, her message was as old as the American Revolution Don't Tread on Me.From that day forward, pins became part of Albright's diplomatic signature. International leaders were pleased to see her with a shimmering sun on her jacket or a cheerful ladybug; less so with a crab or a menacing wasp. Albright used pins to emphasize the importance of a negotiation, signify high hopes, protest the absence of progress, and show pride in representing America, among other purposes.Part illustrated memoir, part social history, Read My Pins provides an intimate look at Albright's life through the brooches she wore. Her collection is both international and democratic dime-store pins share pride of place with designer creations and family heirlooms. Included are the antique eagle purchased to celebrate Albright's appointment as secretary of state, the zebra pin she wore when meeting Nelson Mandela, and the Valentine's Day heart forged by Albright's five-year-old daughter. Read My Pins features more than 200 photographs, along with compelling and often humorous stories about jewelry, global politics, and the life of one of America's most accomplished and fascinating diplomats.

The rivalry between the brilliant seventeenth-century Italian architects Gianlorenzo Bernini and Francesco Borromini is the stuff of legend. Enormously talented and ambitious artists, they met as contemporaries in the building yards of St. Peter's in Rome, became the greatest architects of their era by designing some of the most beautiful buildings in the world, and ended their lives as bitter enemies. Engrossing and impeccably researched, full of dramatic tension and breathtaking insight, The Genius in the Design is the remarkable tale of how two extraordinary visionaries schemed and maneuvered to get the better of each other and, in the process, created the spectacular Roman cityscape of today.

The first history of the legendary knights since the Vatican momentously released the records of their trial and exonerationWho were the TemplarsWhat was the secret of their wealth and powerWhy did the pope and the king of France act to destroy themThe Knights Templar were founded on Christmas Day 1119, on the very spot in Jerusalem where Jesus Christ was crucified. A religious order of fighting knights, the Templars defended the Holy Land and Christian pilgrims in the decades after the First Crusade. Legendary for their bravery and dedication, the Templars became one of the wealthiest and most powerful bodies of the medieval world until they were condemned for heresy two centuries after their foundation, when the order was abolished and its leaders were burned at the stake.In The Templars, renowned historian Michael Haag investigates the origins and history, the enduring myths, and the soaring architecture of an enigmatic order long shrouded in mystery and controversy. The hand of the Templars, many believe, can be found in everything from Cathar heresy to Masonic conspiracies, and the Knights Templar still inspire popular culture, from Indiana Jones to Xbox games, to the novels of Dan Brown.Some images that appeared in the print edition of this book are unavailable in the electronic edition due to rights reasons.

On May 13, 1945, twenty-four American servicemen and WACs boarded a transport plane for a sightseeing trip over Shangri-La, a beautiful and mysterious valley deep within the jungle-covered mountains of Dutch New Guinea.Unlike the peaceful Tibetan monks of James Hilton's bestselling novel Lost Horizon, this Shangri-La was home to spear-carrying tribesmen, warriors rumored to be cannibals. But the pleasure tour became an unforgettable battle for survival when the plane crashed. Miraculously, three passengers pulled through. Margaret Hastings, barefoot and burned, had no choice but to wear her dead best friend's shoes. John McCollom, grieving the death of his twin brother also aboard the plane, masked his grief with stoicism. Kenneth Decker, too, was severely burned and suffered a gaping head wound.Emotionally devastated, badly injured, and vulnerable to the hidden dangers of the jungle, the trio faced certain death unless they left the crash site. Caught between man-eating headhunters and enemy Japanese, the wounded passengers endured a harrowing hike down the mountainside a journey into the unknown that would lead them straight into a primitive tribe of superstitious natives who had never before seen a white man or woman.Drawn from interviews, declassified U.S. Army documents, personal photos and mementos, a survivor's diary, a rescuer's journal, and original film footage, Lost in Shangri-La recounts this incredible true-life adventure for the first time. Mitchell Zuckoff reveals how the determined trio dehydrated, sick, and in pain traversed the dense jungle to find help; how a brave band of paratroopers risked their own lives to save the survivors; and how a cowboy colonel attempted a previously untested rescue mission to get them out.By trekking into the New Guinea jungle, visiting remote villages, and rediscovering the crash site, Zuckoff also captures the contemporary natives remembrances of the long-ago day when strange creatures fell from the sky. A riveting work of narrative nonfiction that vividly brings to life an odyssey at times terrifying, enlightening, and comic, Lost in Shangri-La is a thrill ride from beginning to end.

Genetic science is about to radically alter our lives. Sooner than you can imagine, human beings will be capable of diagnosing their own illnesses, designating the sex of their children, even designing the food they eat -- all as easily as using a cell phone. Now is the time for every one of us to take control of our DNA, and one man is uniquely qualified to show us how: Glenn McGee, bioethicist at the University of Pennsylvania, pioneer in the study of "home genetics," and the acknowledged wunderkind of the exciting world found at the nexus of life science and computer technology.One of the most respected authorities in the field of genomics -- the study of the genetic "software" inside plants, animals, and us -- McGee takes us on an eye-opening journey behind the headlines and into the heart of this formidable cutting-edge science. Probing the far-ranging ethical and legal implications of genomic research, McGee tackles its most controversial and hotly debated aspects -- from patenting your DNA to genetic engineering at the supermarket -- and explodes unnecessary fears about this wondrous new knowledge.We live in a brave new world. Beyond Genetics provides us with the knowledge we need to take the right steps forward into tomorrow ... and beyond.

Traditionally, women share their secrets with their hairdressers. But what about their manicurists, masseurs, chi gong teachers, and tattoo artistsIn Damage Control, women wax poetic about the experts and gurus who help them love themselves, sharing stories of everything from friendships born in the make-up chair to the utter dismay of a truly horrible haircut. Minnie Driver finally meets a Frenchman who understands her hair . . . and tries to teach her not to hate it.Marian Keyes remembers the blow-dry that pushed her over the edge.Francesca Lia Block tells the ugly story of the plastic surgeon who promised to make her beautiful.Rose McGowan explains why it's harder to be depressed when you're glamorous . . . and shows how it takes a village to transform from mere mortal to movie star.Witty and wise, Damage Control is an intimate, sometimes dark, look at our experiences with the professionals who pluck, prod, and pamper every inch of our bodies and a reminder why we surrender ourselves to their (hopefully) very capable hands.

He came to mainstream prominence as a machine more human than his creators in Blade Runner, terrified us as a hitchhiker bent on his own death and the death of anyone who got in his way in The Hitcher, and unforgettably portrayed a lonely king roaming the night as a wolf and pining for the love of a hawk during the day in Ladyhawke. Rutger Hauer has dazzled audiences for years with his creepy, inspiring, and villainous portrayals of everyone from a cold-blooded terrorist in Nighthawks to a blind martial arts master in Blind Fury, but his movie career was nothing compared to his real-life adventures of riding horses, sword fighting, and leaving home at fifteen to scrub decks on a freighter and explore the world.From poverty to working with a traveling theater troupe to his breakout European performance in Turkish Delight and working with legendary directors such as Paul Verhoeven (RoboCop and Basic Instinct) and Ridley Scott (Alien and Gladiator), Hauer has collected All Those Moments here.

Military service was once taken for granted as a natural part of good citizenship, and Americans of all classes served during wartime.Not anymore.As Kathy Roth-Douquet and Frank Schaeffer assert in this groundbreaking work, there is a glaring disconnect between the "all volunteer military" and the rest of us. And as that gap between the cultural "elite" and military rank-and-file widens, our country faces a dangerous lack of understanding between those in power and those who defend our way of life.In America, it is increasingly the case that the people who make, support, or protest military policy have no military experience. As a result, the privileged miss the benefits of military service -- leadership, experience helpful to their future roles in public life, and exposure to a broader cross section of citizens -- while the military feels under-supported and morally distanced from the rest of the country. And when only a handful of members of Congress have military experience or a personal link to someone in uniform, perhaps it becomes too easy (or too hard) to send the military into combat.Based on research and including the voices of many young military members who understand firsthand the value of service, AWOL is also a very personal book. Frank Schaeffer, father of a former enlisted Marine, knows the anguish and pride that millions of American parents feel every day as their children are off fighting a war in a foreign land. Kathy Roth-Douquet, wife of a career officer, has experienced the struggle of trying to keep the family together with a husband at war as well as the often untold satisfaction of raising children in an ethic of service. To the authors and numerous other families who are intimately acquainted with the glory and the sacrifice of military service, America needs a wake-up call before it's too late.
