But how does virality actually work? In The Rules of Contagion, epidemiologist Adam Kucharski explores topics including gun violence, online manipulation, and, of course, outbreaks of disease to show how much we get wrong about contagion, and how astonishing the real science is.Why did the president retweet a Mussolini quote as his own? Why do financial bubbles take off so quickly? And why are disinformation campaigns so effective? By uncovering the crucial factors driving outbreaks, we can see how things really spread -- and what we can do about it.Whether you are an author seeking an audience, a defender of truth, or simply someone interested in human social behavior, The Rules of Contagion is an essential guide to modern life.

    Armed with a healthy dose of wit and curiosity, medical journalist Randi Hutter Epstein reveals the “invigorating history” (Nature) of hormones and the age-old quest to control them through the back rooms, basements, and labs where endocrinology began.

    Randall never gave sleep much thought. That is, until he began sleepwalking. One midnight crash into a hallway wall sent him on an investigation into the strange science of sleep.In Dreamland, Randall explores the research that is investigating those dark hours that make up nearly a third of our lives. Taking readers from military battlefields to children’s bedrooms, Dreamland shows that sleep isn't as simple as it seems. Why did the results of one sleep study change the bookmakers’ odds for certain Monday Night Football games? Do women sleep differently than men? And if you happen to kill someone while you are sleepwalking, does that count as murder?This book is a tour of the often odd, sometimes disturbing, and always fascinating things that go on in the peculiar world of sleep. You’ll never look at your pillow the same way again.

    But in the modern world, the breast is changing. Breasts are getting bigger, arriving earlier, and attracting newfangled chemicals. Increasingly, the odds are stacked against us in the struggle with breast cancer, even among men. What makes breasts so mercurial—and so vulnerable?In this informative and highly entertaining account, intrepid science reporter Florence Williams sets out to uncover the latest scientific findings from the fields of anthropology, biology, and medicine. Her investigation follows the life cycle of the breast from puberty to pregnancy to menopause, taking her from a plastic surgeon’s office where she learns about the importance of cup size in Texas to the laboratory where she discovers the presence of environmental toxins in her own breast milk. The result is a fascinating exploration of where breasts came from, where they have ended up, and what we can do to save them.

    According to this false-yet-familiar story, the divisions between men and women are in nature alone and not part of culture. Drawing on evolutionary science, psychology, neuroscience, endocrinology, and philosophy, Testosterone Rex disproves this ingrained myth and calls for a more equal society based on both sexes’ full human potential.

    The Salt Fix is essential reading for everyone on the keto diet! We've all heard the recommendation: eat no more than a teaspoon of salt a day for a healthy heart. Health-conscious Americans have hewn to the conventional wisdom that your salt shaker can put you on the fast track to a heart attack, and have suffered through bland but "heart-healthy" dinners as a result.What if the low-salt dogma is wrong?Dr. James DiNicolantonio has reviewed more than five hundred publications to unravel the impact of salt on blood pressure and heart disease. He's reached a startling conclusion: The vast majority of us don't need to watch our salt intake. In fact, for most of us, more salt would be advantageous to our nutrition--especially for those of us on the keto diet, as keto depletes this important mineral from our bodies. The Salt Fix tells the remarkable story of how salt became unfairly demonized--a never-before-told drama of competing egos and interests--and took the fall for another white crystal: sugar.According to The Salt Fix, too little salt can: - Make you crave sugar and refined carbs - Send the body into semistarvation mode - Lead to weight gain, insulin resistance, type 2 diabetes, cardiovascular disease, chronic kidney disease, and increased blood pressure and heart rateBut eating the salt you desire can improve everything, from your sleep, energy, and mental focus to your fitness, fertility, and sexual performance. It can even stave off common chronic illnesses, including heart disease.The Salt Fix shows the best ways to add salt back into your diet, offering his transformative five-step program for recalibrating your salt thermostat to achieve your unique, ideal salt intake. Science has moved on from the low-salt dogma, and so should you--your life may depend on it.

    Will Bulsiewicz, or "Dr. B," illuminates in this groundbreaking book, the explosion of studies on the microbiome makes it abundantly clear that elimination diets are in fact hazardous to our health. What studies clearly now show--and what Dr. B preaches with his patients--is that gut health is the key to boosting our metabolism, balancing our hormones, and taming the inflammation that causes a host of diseases. And the scientifically proven way to fuel our guts is with dietary fiber from an abundant variety of colorful plants.Forget about the fiber your grandmother used to take--the cutting-edge science on fiber is incredibly exciting. As Dr. B explains, fiber energizes our gut microbes to create powerhouse postbiotics called short-chain fatty acids (SCFAs) that are essential to our health. SCFAs are scientifically proven to promote weight loss, repair leaky gut, strengthen the microbiome, optimize the immune system, reduce food sensitivities, lower cholesterol, reverse type 2 diabetes, improve brain function, and even prevent cancer. Restrictive fad diets starve the gut of the critical fiber we need, weaken the microbes, and make our system vulnerable.As a former junk-food junkie, Dr. B knows firsthand the power of fiber to dramatically transform our health. The good news is that our guts can be trained. Fiber-rich, real foods--with fruits, vegetables, whole grains, seeds, nuts, and legumes--start working quickly and maintain your long-term health, promote weight loss, and allow you to thrive and feel great from the inside out.With a 28-day jumpstart program with menus and more than 65 recipes, along with essential advice on food sensitivities, Fiber Fueled offers the blueprint to start turbocharging your gut for lifelong health today.

    The popularity of murder mystery books, TV series, and even board games shows that there is an appetite for death, and the more unusual or macabre the method, the better. With gunshots or stabbings the cause of death is obvious, but poisons are inherently more mysterious. How are some compounds so deadly in such tiny amounts?Agatha Christie used poison to kill her characters more often than any other crime fiction writer. The poison was a central part of the novel, and her choice of deadly substances was far from random; the chemical and physiological characteristics of each poison provide vital clues to the discovery of the murderer. Christie demonstrated her extensive chemical knowledge (much of it gleaned by working in a pharmacy during both world wars) in many of her novels, but this is rarely appreciated by the reader.Written by former research chemist Kathryn Harkup, each chapter takes a different novel and investigates the poison used by the murderer. Fact- and fun-packed, A is for Arsenic looks at why certain chemicals kill, how they interact with the body, and the feasibility of obtaining, administering, and detecting these poisons, both when Christie was writing and today.

    Unwittingly, we've been selecting plants that are high in starch and sugar and low in vitamins, minerals, fiber, and antioxidants for more than 400 generations.EATING ON THE WILD SIDE reveals the solution--choosing modern varieties that approach the nutritional content of wild plants but that also please the modern palate. Jo Robinson explains that many of these newly identified varieties can be found in supermarkets and farmer's market, and introduces simple, scientifically proven methods of preparation that enhance their flavor and nutrition. Based on years of scientific research and filled with food history and practical advice, EATING ON THE WILD SIDE will forever change the way we think about food.Winner of the 2014 IACP Cookbook Award in the category of "Food Matters."

    Our ancestors crossed the Alps in animal skins and colonized the New World in loin cloths. They evaded predators and built civilizations with just their raw brainpower and inner grit. But things have changed and now comfort is king. Today we live in the thrall of constant climate control and exercise only when our office schedules permit. The technologies that we use to make us comfortable are so all-encompassing that they sever the biological link to a changing environment. Now we hate the cold and the heat. We suffer from autoimmune diseases. And many of us are chronically overweight. Most of us don't even realize that natural variation—sweating and shivering—is actually good for us. What Doesn't Kill Us uncovers how just about anyone can reclaim a measure of our species' evolutionary strength by tapping into the things that feel uncomfortable. When we slightly reimagine how our body fits into the world, we can condition ourselves to find resilience in unfamiliar environments. The feeling that something is missing from our daily routines is growing and has spawned a movement. Every year, millions of people forgo traditional gyms and push the limits of human endurance by doing boot camp style workouts in raw conditions. These extreme athletes train in CrossFit boxes, compete in Tough Mudders and challenge themselves in Spartan races. They are connecting with their environment and, whether they realize it or not, are changing their bodies. No one exemplifies this better than Dutch fitness guru Wim Hof, whose remarkable ability to control his body temperature in extreme cold has sparked a whirlwind of scientific study. Because of him, scientists in the United States and Europe are just beginning to understand how cold adaptation might help combat autoimmune diseases and chronic pains and, in some cases, even reverse diabetes. Award winning investigative journalist, Scott Carney dives into the fundamental philosophy at the root of this movement in three interlocking narratives. His own journey culminates in a record bending 28-hour climb up to the snowy peak of Mt. Kilimanjaro wearing nothing but a pair of running shorts and sneakers.

    Scientists in every field are desperate to explain this epidemic and stave off a modern health disaster. But what’s to blame? Carbs, fat or sugar? Gut microbes or genes? Laziness or poverty?In The Truth About Fat, Anthony Warner scrutinises the explanations of experts in every field, speaks to those who dedicate their lives to helping obese people and to others who live with their own larger bodies every day. As he lays out the best evidence available, he rails against quack theories preying on the desperate and considers whether we are blaming our own bodies for other people's ignorance and cruelty. What remains is the unvarnished truth about one of the great preoccupations of our age.

    He also weighed 300 pounds, despite the fact that he was doing what doctors recommended: eating 1,800 calories a day and working out 90 minutes a day, six times a week. When his excess fat started causing brain fog and food cravings sapped his energy and willpower, Asprey turned to the same hacking techniques that made his fortune to "hack" his own biology, investing more than $300,000 and 15 years to uncover what was hindering his energy, performance, appearance, and happiness. From private brain EEG facilities to remote monasteries in Tibet, through radioactive brain scans, blood chemistry work, nervous system testing, and more, he explored traditional and alternative technologies to reach his physical and mental prime. The result? The Bulletproof Diet, an anti-inflammatory program for hunger-free, rapid weight loss and peak performance. The Bulletproof Diet will challenge—and change—the way you think about weight loss and wellness. You will skip breakfast, stop counting calories, eat high levels of healthy saturated fat, work out and sleep less, and add smart supplements.In doing so, you'll gain energy, build lean muscle, and watch the pounds melt off. By ditching traditional "diet" thinking, Asprey went from being overweight and sick in his twenties to maintaining a 100-pound weight loss, increasing his IQ, and feeling better than ever in his forties. The Bulletproof Diet is your blueprint to a better life.
