One thing, however, is clear: Sleep is just as essential to life as nutrition and exercise. This course examines the latest research on the crucial phenomenon of sleep.

    The alimentary canal is classic Mary Roach terrain: the questions explored in Gulp are as taboo, in their way, as the cadavers in Stiff and every bit as surreal as the universe of zero gravity explored in Packing for Mars. Why is crunchy food so appealing? Why is it so hard to find words for flavors and smells? Why doesn’t the stomach digest itself? How much can you eat before your stomach bursts? Can constipation kill you? Did it kill Elvis? In Gulp we meet scientists who tackle the questions no one else thinks of—or has the courage to ask. We go on location to a pet-food taste-test lab, a fecal transplant, and into a live stomach to observe the fate of a meal. With Roach at our side, we travel the world, meeting murderers and mad scientists, Eskimos and exorcists (who have occasionally administered holy water rectally), rabbis and terrorists—who, it turns out, for practical reasons do not conceal bombs in their digestive tracts.Like all of Roach’s books, Gulp is as much about human beings as it is about human bodies.

    Drawing on momentous (yet dimly remembered) historical epidemics, contemporary analyses, and cutting-edge research from a range of scientific disciplines, bestselling author, physician, sociologist, and public health expert Nicholas A. Christakis explores what it means to live in a time of plague—an experience that is paradoxically uncommon to the vast majority of humans who are alive, yet deeply fundamental to our species.Unleashing new divisions in our society as well as opportunities for cooperation, this 21st-century pandemic has upended our lives in ways that will test, but not vanquish, our already frayed collective culture. Featuring new, provocative arguments and vivid examples ranging across medicine, history, sociology, epidemiology, data science, and genetics, Apollo's Arrow envisions what happens when the great force of a deadly germ meets the enduring reality of our evolved social nature.

    It's an occasionally ribald, frequently witty and unerringly erudite guided tour of the secret labyrinth that lurks beneath the English language, taking in monks and monkeys, film buffs and buffaloes, and explaining precisely what the Rolling Stones have to do with gardening.

    As much as we'd like to cultivate these same skills, the truth is that you cannot know how a lawyer thinks and works without studying the law itself.Now there's an easier way to get the same foundational knowledge as lawyers - without the enormous time and financial commitment. Over the span of 48 lectures, four experienced lawyers and teachers recreate key parts of the first-year law student experience, introducing you to main areas of law most every beginning student studies.You'll start with 12 lectures on litigation and legal practice that offer eye-opening answers to many questions about the art and craft of legislation. In the second 12 lectures, you'll learn how criminal law and procedure - an area of law dramatized by countless TV shows - really works. Additional lectures investigate the civic procedures courts follow to resolve disputes about substantive rights and examine broader questions any system of litigation must address. And 12 lectures are devoted entirely to the stranger-than-fiction topic of tort law.Enriched with famous cases from the annals of American law and powerful arguments by some of history's most successful lawyers, these lectures offer access to an often intimidating, surprisingly accessible, and civically important field.

    It was the end. When it came to my dad though, no amount of rational thought could outweigh my feelings. I watched the footage over and over again, trying to validate my hopes and dreams, believing there was a minute possibility he made it out of the building alive.”After his father died on 9/11 in the World Trade Center, nine-year-old Matthew John Bocchi began an obsessive quest to find out exactly how he died. He researched video tapes, pictures, blogs, anything that could potentially answer the question looming in his mind: was his father one of the jumpers? In the first memoir told by a child of 9/11, Matt intimately delves into the psychological and emotional torment that ensued after his father’s death. With heartbreaking vulnerability, he details how his incessant quest resulted in a devastating act of violence that stripped his innocence as a young man. As Matt spirals down a bottomless pit of drug abuse, he willfully risks his life in search of the next high—all in an attempt to forget his past.  Now at twenty-eight years old and sober, he recounts his unique story—one full of heartbreak and despair, grief and uncertainty, but most importantly, happiness and hope. The lesson he teaches us is clear but intricate: No matter how far you fall, you can always rise again. No matter how far you stray, you can always find your way home. And no matter how wide you sway, you can always pick up the pieces and stand tall.

    Tracing the rise, fall, and alarming resurrection of the digital mafia behind the two largest spam pharmacies and countless viruses, phishing, and spyware attacks he delivers the first definitive narrative of the global spam problem and its threat to consumers everywhere.Blending cutting-edge research, investigative reporting, and firsthand interviews, this terrifying true story reveals how we unwittingly invite these digital thieves into our lives every day. From unassuming computer programmers right next door to digital mobsters like "Cosma" who unleashed a massive malware attack that has stolen thousands of Americans' logins and passwords, Krebs uncovers the shocking lengths to which these people will go to profit from our data and our wallets.Not only are hundreds of thousands of Americans exposing themselves to fraud and dangerously toxic products from rogue online pharmacies, but even those who never open junk messages are at risk. As Krebs notes, spammers can—and do—hack into accounts through these emails, harvest personal information like usernames and passwords, and sell them on the digital black market. The fallout from this global epidemic doesn't just cost consumers and companies billions, it costs lives too.Fast-paced and utterly gripping, Spam Nation ultimately proposes concrete solutions for protecting ourselves online and stemming this tidal wave of cybercrime, before it's too late."Krebs's talent for exposing the weaknesses in online security has earned him respect in the IT business and loathing among cybercriminals. His track record of scoops has helped him become the rare blogger who supports himself on the strength of his reputation for hard-nosed reporting." Bloomberg Businessweek

    It was an act that forced the permanent evacuation of a city, killed thousands and crippled the Soviet Union. The event spawned decades of conflicting, exaggerated and inaccurate stories. This book, the result of five years of research, presents an accessible but comprehensive account of what really happened. From the desperate fight to prevent a burning reactor core from irradiating eastern Europe, to the self-sacrifice of the heroic men who entered fields of radiation so strong that machines wouldn’t work, to the surprising truth about the legendary ‘Chernobyl divers’, all the way through to the USSR’s final show-trial. The historical narrative is interwoven with a story of the author’s own spontaneous journey to Ukraine’s still-abandoned city of Pripyat and the wider Chernobyl Zone. Complete with over 45 pages of photographs of modern-day Pripyat and technical diagrams of the power station, Chernobyl 01:23:40 is a fascinating new account of the world’s worst nuclear disaster.

    Over time, eight key technologies gradually freed us from the limitations of our animal origins.The fabrication of weapons, the mastery of fire, and the technologies of clothing and shelter radically restructured the human body, enabling us to walk upright, shed our body hair, and migrate out of tropical Africa. Symbolic communication transformed human evolution from a slow biological process into a fast cultural process. The invention of agriculture revolutionized the relationship between humanity and the environment, and the technologies of interaction led to the birth of civilization. Precision machinery spawned the industrial revolution and the rise of nation-states; and in the next metamorphosis, digital technologies may well unite all of humanity for the benefit of future generations.Synthesizing the findings of primatology, paleontology, archeology, history, and anthropology, Richard Currier reinterprets and retells the modern narrative of human evolution that began with the discovery of Lucy and other Australopithecus fossils. But the same forces that allowed us to integrate technology into every aspect of our daily lives have also brought us to the brink of planetary catastrophe. Unbound explains both how we got here and how human society must be transformed again to achieve a sustainable future.Technology: “The deliberate modification of any natural object or substance with forethought to achieve a specific end or to serve a specific purpose.”
