Dem Rätsel des Riechens auf der Spur: Hanns Hatt erzählt Grundlagen der Duftwahrnehmung
Bevor Lebewesen sehen und hören konnten, waren sie in der Lage zu riechen. In 500 Millionen Jahren der Evolution war es der Geruchssinn, der dem Gehirn ein wichtiges Fenster zur Welt geöffnet hat, der informierte, was essbar ist oder giftig, welches der richtige Sexualpartner ist, und der zu Orientierung, Warnung und Sozialverhalten beitrug. Bei den primitiven Wirbeltieren machte das Riechhirn den größten Teil des gesamten Gehirns aus und die neuronalen Mechanismen der Signalverarbeitung, die sich dabei entwickelten, standen Modell für alle anderen Sinne wie Sehen oder Hören. Trotz seiner ungeheuren Komplexität und Leistungsfähigkeit organisiert sich auch das menschliche Gehirn immer um das olfaktorische System. Für den Menschen hat dieses archaische Sinnessystem weit weniger an Bedeutung verloren, als gemeinhin angenommen wird. Düfte können Auslöser für Sympathie und Antipathie sein, Stimmungen und Emotionen beeinflussen, das Sozial- und Sexualverhalten steuern, den Hormonstatus verändern und als chemische Kommunikationsmittel dienen. Auch körperliche Funktionen können direkt beeinträchtigt werden. Bislang war nur wenig über den molekularen Hintergrund der Duftwahrnehmung bekannt. Die Komplexität der Geruchswelt ist wohl Hauptgrund für dieses Wissensdefizit. Wir können unbegrenzt viele Duftstoffe wahrnehmen und mehr als 10.000, selbst in äußerst geringen Konzentrationen, unterscheiden. Was aber geschieht, wenn ein Duftmolekül auf der Riechschleimhaut absorbiert wird und von der Riechsinneszelle ein elektrischer Strom zu unserem Riechhirn weitergeleitet wird?

What is Life?: With Mind and Matter and Autobiographical Sketches
Nobel laureate Erwin Schrödinger's What is Life? is one of the great science classics of the twentieth century. A distinguished physicist's exploration of the question which lies at the heart of biology, it was written for the layman, but proved one of the spurs to the birth of molecular biology and the subsequent discovery of the structure of DNA. The philosopher Karl Popper hailed it as a "beautiful and important book" by "a great man to whom I owe a personal debt for many exciting discussions." It appears here together with "Mind and Matter," his essay investigating a relationship which has eluded and puzzled philosophers since the earliest times. Schrödinger asks what place consciousness occupies in the evolution of life, and what part the state of development of the human mind plays in moral questions. Brought together with these two classics are Schrödinger's autobiographical sketches. They offer a fascinating fragmentary account of his life as a background to his scientific writings, making this volume a valuable addition to the shelves of scientist and layman alike.

Did You Just Eat That?: Two Scientists Explore Double-Dipping, the Five-Second Rule, and other Food
Is the five-second rule legitimate? Are electric hand dryers really bacteria blowers? Am I spraying germs everywhere when I blow on my birthday cake? How gross is backwash? When it comes to food safety and germs, there are as many common questions as there are misconceptions. And yet there has never been a book that clearly examines the science behind these important issues-until now. In Did You Just Eat That? food scientists Paul Dawson and Brian Sheldon take listeners into the lab to show, for example, how they determine the amount of bacteria that gets transferred by sharing utensils or how many microbes live on restaurant menus. The authors list their materials and methods (in case you want to replicate the experiments), guide us through their results, and offer in-depth explanations of good hygiene and microbiology. Written with candid humor, this fascinating book will reveal surprising answers to the most frequently debated-and also the weirdest-questions about food and germs, sure to satisfy anyone who has ever wondered: should I really eat that?

The Magic Feather Effect: The Science of Alternative Medicine and the Surprising Power of Belief
The acclaimed author of Pandora's Lunchbox and former New York Times reporter takes an enlightening, engaging deep dive into the world of alternative medicine and the surprising science that explains why it may work. We all know someone who has had a seemingly miraculous cure from an alternative form of medicine: a friend whose chronic back pain vanished after sessions with an acupuncturist or chiropractor; a relative with digestive issues who recovered with herbal remedies; a colleague whose autoimmune disorder went into sudden inexplicable remission thanks to an energy healer or healing retreat. The tales are far too common to be complete fabrications, yet too anecdotal and outside the medical mainstream to be taken seriously scientifically. How do we explain them and the growing popularity of alternative medicine more generally? Is there a biological basis for practices like acupuncture, tai chi, chiropractic, and energy healing? Who are the faithful patients and practitioners who tell these stories and speak of such mystical-seeming concepts as qi, chakras, and meridians in the first place? In The Magic Feather Effect, author and journalist Melanie Warner attempts to answer these questions, taking us on a vivid, fascinating journey through the world of alternative medicine. Crossing continents and sides of the debate, visiting prestigious research clinics and ordinary people's homes, she investigates the scientific underpinning for the purportedly magical results of these practices and reveals not only the medical power of beliefs and placebo effects, but also the range, limits, and uses of the surprising system of self-healing that resides inside us. Equal parts helpful, illuminating, and compelling, The Magic Feather Effect is a brilliant exploration of some of the world's most popular health treatments, the people who seek them, the scientists who study them, and the reasons they may work.

Rewired: An Unlikely Doctor, a Brave Amputee, and the Medical Miracle That Made History
A raccoon bite on the arm doesn't seem that serious, but it soon becomes a life-or-death medical crisis for Melissa Loomis. After days of treatment for recurring infection, it becomes obvious that her arm must be amputated. Dr. Ajay Seth, the son of immigrant parents from India and a local orthopaedic surgeon in private practice, performs his first-ever amputation procedure. In the months that follow, divine intervention, combined with Melissa's determination and Dr. Seth's disciplined commitment and dedication to his patients, brings about the opportunity for a medical breakthrough that will potentially transform the lives of amputees around the world. Rewired is the inspirational, miraculous story of Dr. Seth's revolutionary surgery that allows Melissa to not just move a prosthetic arm simply by thinking, but to actually feel with the prosthetic hand, just as she would with her natural arm. This resulted in what others have recognized as the world's most advanced amputee, all done from Dr. Seth's private practice in a community hospital, using a local staff, and with no special training or extensive research funding.

Gut Reactions: The Science of Weight Gain and Loss
How much do you really know about how the human body works, and how it reacts to food, exercise, nutrition, and the environment? While most of us have read about at least one fad diet, we're left wondering about the greater biochemistry, psychology, sociology, and physiology of the obesity crisis in the United States. Gut Reactions by chemist Simon Quellen Field shows us how our bodies react to food and the environment, and how our brain affects what and how much we eat, and in turn, is affected by what we eat. It shows why some diets work for some people but not for others, based on genetics, previous weight history, brain chemistry, environmental cues, and social pressures. It explores how dozens of hormones affect hunger and satiety and interact with the brain and the gut to regulate feeding behavior. And it explains the addictive nature of foods that interact with the same dopamine and opioid receptors in the brain that cocaine, heroin, amphetamines, and nicotine do. Whether you're looking to lose weight, put on muscle mass, or simply understand how your metabolism or gut microbiome is affecting your food cravings, Field has a scientific answers for you.

Understanding the Brain: From Cells to Behavior to Cognition
An examination of what makes us human and unique among all creatures-our brains No listener curious about our "little gray cells" will want to pass up Harvard neuroscientist John E. Dowling's brief introduction to the brain. In this up-to-date revision of his 1998 book Creating Mind, Dowling conveys the essence and vitality of the field of neuroscience-examining the progress we've made in understanding how brains work, and shedding light on discoveries having to do with aging, mental illness, and brain health. The first half of the book provides the nuts-and-bolts necessary for an up-to-date understanding of the brain. Covering the general organization of the brain, early chapters explain how cells communicate with one another to enable us to experience the world. The rest of the book touches on higher-level concepts such as vision, perception, language, memory, emotion, and consciousness. Lucidly written, this introduction elegantly reveals the beauty of the organ that makes us uniquely human.

Uncertain Peril: Genetic Engineering and the Future of Seeds
Life on earth is facing unprecedented challenges from global warming, war, and mass extinctions. The plight of seeds is a less visible but no less fundamental threat to our survival. Seeds are at the heart of the planet's life-support systems. Their power to regenerate and adapt are essential to maintaining our food supply and our ability to cope with a changing climate. In Uncertain Peril, environmental journalist Claire Hope Cummings exposes the stories behind the rise of industrial agriculture and plant biotechnology, the fall of public interest science, and the folly of patenting seeds. She examines how farming communities are coping with declining water, soil, and fossil fuels, as well as with new commercial technologies. Will genetically engineered and 'terminator' seeds lead to certain promise, as some have hoped, or are we embarking on a path of uncertain peril? Will the 'doomsday vault' under construction in the Arctic, designed to store millions of seeds, save the genetic diversity of the world's agriculture? To answer these questions and others, Cummings takes readers from the Fertile Crescent in Iraq to the island of Kaua'i in Hawai'i; from Oaxaca, Mexico, to the Mekong Delta in Vietnam. She examines the plight of farmers who have planted transgenic seeds and scientists who have been persecuted for revealing the dangers of modified genes. At each turn, Cummings looks deeply into the relationship between people and plants. She examines the possibilities for both scarcity and abundance and tells the stories of local communities that are producing food and fuel sustainably and providing for the future. The choices we make about how we feed ourselves now will determine whether or not seeds will continue as a generous source of sustenance and remain the common heritage of all humanity. It comes down to this: whoever controls the future of seeds controls the future of life on earth. Uncertain Peril is a powerful reminder that what's at stake right now is nothing less than the nature of the future.
