Humans have feared them for centuries, long considering them the assassins and pariahs of the natural world.Now, in Venomous, the biologist Christie Wilcox investigates and illuminates the animals of our nightmares, arguing that they hold the keys to a deeper understanding of evolution, adaptation, and immunity. She reveals just how venoms function and what they do to the human body. With Wilcox as our guide, we encounter a jellyfish with tentacles covered in stinging cells that can kill humans in minutes; a two-inch caterpillar with toxic bristles that trigger hemorrhaging; and a stunning blue-ringed octopus capable of inducing total paralysis. How do these animals go about their deadly work? How did they develop such intricate, potent toxins? Wilcox takes us around the world and down to the cellular level to find out.Throughout her journey, Wilcox meets the intrepid scientists who risk their lives studying these lethal beasts, as well as “self-immunizers” who deliberately expose themselves to snakebites. Along the way, she puts her own life on the line, narrowly avoiding being envenomated herself. Drawing on her own research, Wilcox explains how venom scientists are untangling the mechanisms of some of our most devastating diseases, and reports on pharmacologists who are already exploiting venoms to produce lifesaving drugs. We discover that venomous creatures are in fact keystone species that play crucial roles in their ecosystems and ours—and for this alone, they ought to be protected and appreciated.Thrilling and surprising at every turn, Venomous will change everything you thought you knew about the planet’s most dangerous animals.

    In a "witty, erudite, and entertaining" (Esquire) style, Simon Garfield explains how the experimental mishap that produced an odd shade of purple revolutionized fashion, as well as industrial applications of chemistry research. Occasionally honored in certain colleges and chemistry clubs, Perkin until now has been a forgotten man.

    When the cyborg arrives, she senses a worthy and dangerous opponent--one that's been dead for 800 years...

    

    It has been inspired by the scientific ferment that swept through Britain at the end of the 18th century, and which Holmes now radically redefines as 'the revolution of Romantic Science'.

    Originating separately in both ancient Greece and India, the concept of the atom persisted for centuries, despite often running afoul of conventional thinking. Until the twentieth century, no direct evidence for atoms existed. Today it is possible to actually observe atoms using a scanning tunneling microscope. The book begins with the story of the earliest atomists - the ancient Greek philosophers Leucippus, Democritus, and Epicurus, and the Latin poet Lucretius. As the author notes, the idea of elementary particles as the foundation of reality had many opponents throughout history - from Aristotle to Christian theologians and even some nineteenth-century chemists and philosophers. While theists today accept that the evidence for the atomic theory of matter is overwhelming, they reject the atheistic implications of that theory.

    It can be slipped into a drink, smeared onto the tip of an arrow or the handle of a door, even filtered through the air we breathe. But how exactly do these poisons work to break our bodies down, and what can we learn from the damage they inflict?In a blend of popular science, medical history, and true crime, Dr. Neil Bradbury explores the morbidly captivating method of murder from a cellular level. Alongside real-life accounts of murderers and their crimes—some notorious, some forgotten, some still unsolved—are the stories of the poisons involved: eleven molecules of death that work their way through the human body and, paradoxically, illuminate the way in which our bodies function.Drawn from historical records and current news headlines, A Taste for Poison weaves together the tales of spurned lovers, shady scientists, medical professionals and political assassins to show how the precise systems of the body can be impaired to lethal effect through the use of poison. From the deadly origins of the gin & tonic cocktail to the arsenic-laced wallpaper in Napoleon’s bedroom.

    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.

    Czerski provides the tools to alter the way we see everything around us by linking ordinary objects and occurrences, like popcorn popping, coffee stains, and fridge magnets, to big ideas like climate change, the energy crisis, or innovative medical testing. She provides answers to vexing questions: How do ducks keep their feet warm when walking on ice? Why does it take so long for ketchup to come out of a bottle? Why does milk, when added to tea, look like billowing storm clouds? In an engaging voice at once warm and witty, Czerski shares her stunning breadth of knowledge to lift the veil of familiarity from the ordinary.

    When temperatures drop below 56°F, tin crumbles into powder. Were the soldiers of the Grande Armée acutee fatally weakened by cold because the buttons of their uniforms fell apart? How different our world might be if tin did not disintegrate at low temperatures and the French had continued their eastward expansion! This fascinating book tells the stories of seventeen molecules that, like the tin of those buttons, greatly influenced the course of history. These molecules provided the impetus for early exploration and made possible the ensuing voyages of discovery. They resulted in grand feats of engineering and spurred advances in medicine; lie behind changes in gender roles, in law, and in the environment; and have determined what we today eat, drink, and wear. Showing how a change as small as the position of an atom can lead to enormous differences in the properties of a substance, the authors reveal the astonishing chemical connections among seemingly unrelated events. Napoleon's Buttons offers a novel way to understand how our contemporary world works and how our civilization has been shaped over time.

    Bringing the instruments and experimental techniques of the laboratory into the kitchen, This uses recent research in the chemistry, physics, and biology of food to challenge traditional ideas about cooking and eating. What he discovers will entertain, instruct, and intrigue cooks, gourmets, and scientists alike.Molecular Gastronomy, This's first work to appear in English, is filled with practical tips, provocative suggestions, and penetrating insights. This begins by reexamining and debunking a variety of time-honored rules and dictums about cooking and presents new and improved ways of preparing a variety of dishes from quiches and quenelles to steak and hard-boiled eggs. He goes on to discuss the physiology of flavor and explores how the brain perceives tastes, how chewing affects food, and how the tongue reacts to various stimuli. Examining the molecular properties of bread, ham, foie gras, and champagne, the book analyzes what happens as they are baked, cured, cooked, and chilled.Looking to the future, Herv' This imagines new cooking methods and proposes novel dishes. A chocolate mousse without eggs? A flourless chocolate cake baked in the microwave? Molecular Gastronomy explains how to make them. This also shows us how to cook perfect French fries, why a souffl' rises and falls, how long to cool champagne, when to season a steak, the right way to cook pasta, how the shape of a wine glass affects the taste of wine, why chocolate turns white, and how salt modifies tastes.
