    Coffee. Sunscreen. Vapes. George Zaidan reveals what will kill you, what won't, and why--explained with high-octane hilarity, hysterical hijinks, and other things that don't begin with the letter H. INGREDIENTS offers the perspective of a chemist on the stuff we eat, drink, inhale, and smear on ourselves. Apart from the burning question of whether you should eat that Cheeto, Zaidan explores a range of topics. Here's a helpful guide:Stuff in this book: - How bad is processed food? How sure are we?- Is sunscreen safe? Should you use it?- Is coffee good or bad for you?- What's your disease horoscope?- What is that public pool smell made of?- What happens when you overdose on fentanyl in the sun?- What do cassava plants and Soviet spies have in common?- When will you die?Stuff in other books: - Your carbon footprint- Food sustainability- GMOs- CEO pay- Science funding- Politics- Football- Baseball- Any kind of ball reallyZaidan, an MIT-trained chemist who cohosted CNBC's hit Make Me a Millionaire Inventor and wrote and voiced several TED-Ed viral videos, makes chemistry more fun than Hogwarts as he reveals exactly what science can (and can't) tell us about the packaged ingredients sold to us every day. Sugar, spinach, formaldehyde, cyanide, the ingredients of life and death, and how we know if something is good or bad for us--as well as the genius of aphids and their butts--are all discussed in exquisite detail at breakneck speed.

    It’s what I won a Pulitzer Prize for, years ago. I go to epidemics, wars, places where people are struggling to cope with disasters, and I carefully log the accounts and events, trying to represent the lives and experiences of others. The position of “outsider” is emotionally safe, even as agonizing events unfold. But I could not distance myself from the extraordinary sequence of events that fell on America, and especially my home town of New York City, in 2001. A decade later I am still trying to understand how the attacks on the World Trade Center and the anthrax mailings affected me, and those I love. I heard the first jet slam into the north tower of the World Trade Center, and from the rooftop of my apartment building watched the second commercial jet veer towards lower Manhattan, change its trajectory, and slice across the upper floors of the south tower. I was standing on the Manhattan anchorage of the Brooklyn Bridge when the first tower crumbled like a deflated accordion, spewing dust and debris in every direction and crushing the life out of thousands of people within. And a month later, as people started falling ill from inhalation of anthrax spores, one of the nation’s top bioterrorism experts called me to warn that I was a likely target: Stop opening your mail. The flow of these events, from the hijacking of four commercial jets on September 11th to the November death of an anthrax-infected Connecticut villager, took most of the world population from a remarkably united emotional and political place, to a deeply divided, frustrated, angry position. The arc of the response matters: It ultimately determined the course of historic events worldwide and tore America asunder, the people having lost trust in their government and without it, most forms of social cohesion. By the end of the winter of 2002 the arc had completed, from spectacular unity and confidence in governance to deep division and accusations of American arrogance. Through the frustrated anthrax investigations and drumbeats of war, the global community, especially Americans, moved in just a few months’ time from collectivism to fragmentation.This book is structured in two parts. The first, THE END OF THE AGE OF INNOCENCE, is written in the present tense, describing almost hourly the events that unfolded primarily in Washington DC and New York City over 120 days in the fall and winter of 2001 and 2002. Each day is a chapter that opens with the actual diary entry that I sent on that date to a list of friends all over the world. The entry is followed by a detailed breakdown of the day’s events, unfolding like a novel.Part two, NEW WORLD ORDER, details the repercussions of these events, transformations of critical government institutions, public health disasters, and what, in particular, the specter of terrorism meant for the American people. Revelations abound in this book, including:• The bizarre chemistry of The Plume that rose from the burning crushed World Trade Center for four months, endangering the health of hundreds of thousands of New Yorkers.• Evidence that al-Qaeda may have been behind the anthrax mailings.• Devastating spending and restructuring followed the attacks, leaving the nation less prepared for terrorism ten years later, and broke.• Each incident following the opening of anthrax-laden letters reveals countless errors and misjudgments.• There was no “weapons-grade anthrax” in those letters – a finding with profound health and political implications.

    Like most people, you probably wake up, get hungry for meals and doze off in bed around the same time every day. If you’ve ever experienced jet lag or pulled an all-nighter, you know that this schedule can easily be thrown off kilter. But for some people, that imbalance—difficulty sleeping at night, hunger at odd times, or sudden fatigue at noon—is a constant. If you're one of those people, Dr. Satchin Panda, one of the leading researchers on circadian rhythms, has a plan to reset your body clock.Beginning with an in-depth explanation of the circadian clock—why it’s important, how it works, and how to know it isn’t working—The Circadian Code outlines lifestyle changes to make to get back on track. It's a concrete plan to enhance weight loss, improve sleep, optimize exercise, and manage technology so that it doesn’t interfere with your body’s natural rhythm. Dr. Panda’s life-changing methods show you how to prevent and reverse ailments like diabetes, cancer, and dementia, as well as microbiome conditions like acid reflux, heartburn, and irritable bowel disease.

    Focusing on four specific examples — corn, silkworms, domestic cats, and apples — she traces the histories of species that have been fundamentally altered over the centuries by the whims and needs of people.

    Our intimate connection with the world, skin protects us while advertising our health, our identity, and our individuality. This dazzling synthetic overview, written with a poetic touch and taking many intriguing side excursions, is a complete guidebook to the pliable covering that makes us who we are. Skin: A Natural History celebrates the evolution of three unique attributes of human skin: its naked sweatiness, its distinctive sepia rainbow of colors, and its remarkable range of decorations. Jablonski begins with a look at skin's structure and functions and then tours its three-hundred-million-year evolution, delving into such topics as the importance of touch and how the skin reflects and affects emotions. She examines the modern human obsession with age-related changes in skin, especially wrinkles. She then turns to skin as a canvas for self-expression, exploring our use of cosmetics, body paint, tattooing, and scarification. Skin: A Natural History places the rich cultural canvas of skin within its broader biological context for the first time, and the result is a tremendously engaging look at ourselves.

    It promised to shed light on the deep mysteries of consciousness, as well as offer relief to addicts and the mentally ill. But in the 1960s, with the vicious backlash against the counter-culture, all further research was banned. In recent years, however, work has quietly begun again on the amazing potential of LSD, psilocybin and DMT. Could these drugs in fact improve the lives of many people? Diving deep into this extraordinary world and putting himself forward as a guinea-pig, Michael Pollan has written a remarkable history of psychedelics and a compelling portrait of the new generation of scientists fascinated by the implications of these drugs. How to Change Your Mind is a report from what could very well be the future of human consciousness.

    Otto’s subjects include the pioneering dentist who made Shirley Temple and Judy Garland’s teeth sparkle on the silver screen and helped create the all-American image of “pearly whites”; Deamonte Driver, the young Maryland boy whose tragic death from an abscessed tooth sparked congressional hearings; and a marketing guru who offers advice to dentists on how to push new and expensive treatments and how to keep Medicaid patients at bay.In one of its most disturbing findings, Teeth reveals that toothaches are not an occasional inconvenience, but rather a chronic reality for millions of people, including disproportionate numbers of the elderly and people of color. Many people, Otto reveals, resort to prayer to counteract the uniquely devastating effects of dental pain.Otto also goes back in time to understand the roots of our predicament in the history of dentistry, showing how it became separated from mainstream medicine, despite a century of growing evidence that oral health and general bodily health are closely related.Muckraking and paradigm-shifting, Teeth exposes for the first time the extent and meaning of our oral health crisis. It joins the small shelf of books that change the way we view society and ourselves—and will spark an urgent conversation about why our teeth matter.This is an alternate cover edition of ISBN 9781620971444.

    Jason Fung returns with an eye-opening biography of cancer in which he offers a radical new paradigm for understanding cancer—and issues a call to action for reducing risk moving forward. Our understanding of cancer is slowly undergoing a revolution, allowing for the development of more effective treatments. For the first time ever, the death rate from cancer is showing a steady decline . . . but the “War on Cancer” has hardly been won.In The Cancer Code, Dr. Jason Fung offers a revolutionary new understanding of this invasive, often fatal disease—what it is, how it manifests, and why it is so challenging to treat. In this rousing narrative, Dr. Fung identifies the medical community’s many missteps in cancer research—in particular, its focus on genetics, or what he terms the “seed” of cancer, at the expense of examining the “soil,” or the conditions under which cancer flourishes. Dr. Fung—whose groundbreaking work in the treatment of obesity and diabetes has won him international acclaim—suggests that the primary disease pathway of cancer is caused by the dysregulation of insulin. In fact, obesity and type 2 diabetes significantly increase an individual’s risk of cancer.In this accessible read, Dr. Fung provides a new paradigm for dealing with cancer, with recommendations for what we can do to create a hostile soil for this dangerous seed. One such strategy is intermittent fasting, which reduces blood glucose, lowering insulin levels. Another, eliminating intake of insulin-stimulating foods, such as sugar and refined carbohydrates.For hundreds of years, cancer has been portrayed as a foreign invader we’ve been powerless to stop. By reshaping our view of cancer as an internal uprising of our own healthy cells, we can begin to take back control. The seed of cancer may exist in all of us, but the power to change the soil is in our hands.

    In Dark Banquet, zoologist Bill Schutt takes readers on an entertaining voyage into the world of some of nature’s strangest creatures—the sanguivores. Using a sharp eye and mordant wit, Schutt makes a remarkably persuasive case that vampire bats, leeches, ticks, bed bugs, and other vampires are as deserving of our curiosity as warmer and fuzzier species are—and that many of them are even ­worthy of conservation.Schutt takes us from rural Trinidad to the jungles of Brazil to learn about some of the most reviled, misunderstood, and marvelously evolved animals on our planet: vampire bats. Only recently has fact begun to disentangle itself from fiction concerning these remarkable animals, and Schutt delves into the myths and misconceptions surrounding them. Examining the substance that sustains nature’s vampires, Schutt reveals just how little we actually knew about blood until well into the twentieth century. We revisit George Washington on his deathbed to learn how ideas about blood and the supposedly therapeutic value of bloodletting, first devised by the ancient Egyptians and Greeks, survived into relatively modern times. Schutt also tracks the history of medicinal leech use. Once employed by the tens of millions to drain perceived excesses of blood, today the market for these ancient creatures is booming once again—but for very different reasons.Among the other blood feeders we meet in these pages are bed bugs, or “ninja insects,” which are making a creepy resurgence in posh hotels and well-kept homes near you. In addition, Dark Banquet details our dangerous and sometimes deadly encounters with ticks, chiggers, and mites (the ­latter implicated in Colony Collapse Disorder—currently devastating honey bees worldwide). Then there are the truly weird—vampire finches. And if you thought piranha were scary, some people believe that the candiru (or willy fish) is the best reason to avoid swimming in the Amazon.Enlightening, alarming, and appealing to our delight in the bizarre, Dark Banquet peers into a part of the natural world to which we are, through our blood, inextricably linked.From the Hardcover edition.

    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.

    She draws on conversations with hundreds of the world's top scientists and on her own work as a Pulitzer Prize-winning writer for the New York Times to create a thoroughly entertaining guide to scientific literacy. Angier's gifts are on full display in The Canon, an ebullient celebration of science that stands to become a classic. The Canon is vital reading for anyone who wants to understand the great issues of our time -- from stem cells and bird flu to evolution and global warming. And it's for every parent who has ever panicked when a child asked how the earth was formed or what electricity is. Angier's sparkling prose and memorable metaphors bring the science to life, reigniting our own childhood delight in discovering how the world works. "Of course you should know about science," writes Angier, "for the same reason Dr. Seuss counsels his readers to sing with a Ying or play Ring the Gack: These things are fun and fun is good." The Canon is a joyride through the major scientific disciplines: physics, chemistry, biology, geology, and astronomy. Along the way, we learn what is actually happening when our ice cream melts or our coffee gets cold, what our liver cells do when we eat a caramel, why the horse is an example of evolution at work, and how we're all really made of stardust. It's Lewis Carroll meets Lewis Thomas -- a book that will enrapture, inspire, and enlighten.

    Many books on the plague rely on statistics to tell the story: how many people died; how farm output and trade declined. But statistics can’t convey what it was like to sit in Siena or Avignon and hear that a thousand people a day are dying two towns away. Or to have to chose between your own life and your duty to a mortally ill child or spouse. Or to live in a society where the bonds of blood and sentiment and law have lost all meaning, where anyone can murder or rape or plunder anyone else without fear of consequence.In The Great Mortality, author John Kelly lends an air of immediacy and intimacy to his telling of the journey of the plague as it traveled from the steppes of Russia, across Europe, and into England, killing 75 million people—one third of the known population—before it vanished.
