These, along with the introduction of the oral contraceptive, have altered all of our lives. There has also been an increase in the recreational use and abuse of drugs in the Western world. This Very Short Introduction gives a non-technical account of how drugs act on the body and how therapeutic drugs are developed and tested, then goes on to review both legal (prescription, alcohol, nicotine, and caffeine) and illegal drugs, and discuss current ideas about why some drugs are addictive, and whether drug laws need reform.

     Few people know much about stem cell research beyond the ethical questions raised by using embryos. But in the last decade, stem cell research has made huge advances toward eliminating some of our most intractable diseases. Now this sweeping and accessible book introduces us to this cutting-edge science that will revolutionize medicine and change the way we think about and treat disease. Alice Park takes us from stem cell's controversial beginnings to the recent electrifying promise of being able to create the versatile cells without using embryos at all. She shows us how stem cells give researchers an unprecedented ability to study disease while giving patients the promise of replacing diseased cells with healthy new ones. And she profiles the scientists and leaders-many with their own compelling stories-who have fueled the quest and will continue to shape the field in years to come.

    People in this middle place have sustained traumatic brain injuries or are the victims of stroke or degenerative diseases, such as Alzheimer’s and Parkinson’s. Many are oblivious to the outside world, and their doctors believe they are incapable of thought. But a sizeable number are experiencing something different: intact minds adrift deep within damaged brains and bodies. Following Owen’s journey of exciting medical discovery, Into the Gray Zone asks some tough and terrifying questions, such as: What is life like for these patients? What can their families and friends do to help them? What are the ethical implications for religious organizations, politicians, the Right to Die movement, and even insurers? And perhaps most intriguing of all: in defining what a life worth living is, are we too concerned with the physical and not giving enough emphasis to the power of thought? What, truly, defines a satisfying life?

    Striking humanity in waves, the cycle of plagues set the tempo of civilizational growth and decline, since common response to the threat was exclusion—quarantining the sick or keeping them out. But the unprecedented hygiene and medical revolutions of the past two centuries have allowed humanity to free itself from the hold of epidemic cycles—resulting in an urbanized, globalized, and unimaginably wealthy world. However, our development has lately become precarious. Climate and population fluctuations and aspects of our prosperity such as global trade have left us more vulnerable than ever to newly emerging plagues. Greater global cooperation toward sustainable health is urgently required—such as the international efforts to harvest a Covid-19 vaccine—with millions of lives and trillions of dollars at stake. Written as colorful history, The Plague Cycle reveals the relationship between civilization, globalization, prosperity, and infectious disease over the past five millennia. It harnesses history, economics, and public health, and charts humanity’s remarkable progress, providing a fascinating and timely look at the cyclical nature of infectious disease.

    Yet brain scientists have uncovered details every business leader, parent, and teacher should know—like the need for physical activity to get your brain working its best.How do we learn? What exactly do sleep and stress do to our brains? Why is multi-tasking a myth? Why is it so easy to forget—and so important to repeat new knowledge? Is it true that men and women have different brains?In Brain Rules, Dr. John Medina, a molecular biologist, shares his lifelong interest in how the brain sciences might influence the way we teach our children and the way we work. In each chapter, he describes a brain rule—what scientists know for sure about how our brains work—and then offers transformative ideas for our daily lives.Medina’s fascinating stories and infectious sense of humor breathe life into brain science. You’ll learn why Michael Jordan was no good at baseball. You’ll peer over a surgeon’s shoulder as he proves that most of us have a Jennifer Aniston neuron. You’ll meet a boy who has an amazing memory for music but can’t tie his own shoes.You will discover how:Every brain is wired differentlyExercise improves cognitionWe are designed to never stop learning and exploringMemories are volatileSleep is powerfully linked with the ability to learnVision trumps all of the other sensesStress changes the way we learnIn the end, you’ll understand how your brain really works—and how to get the most out of it.

    They ingest 8,500 milligrams of salt a day, double the recommended amount, almost none of which comes from salt shakers. It comes from processed food, an industry that hauls in $1 trillion in annual sales. In Salt Sugar Fat, Pulitzer Prize-winning investigative reporter Michael Moss shows how this happened. Featuring examples from some of the most recognizable (and profitable) companies and brands of the last half century--including Kraft, Coca-Cola, Lunchables, Kellogg, Nestlé, Oreos, Cargill, Capri Sun, and many more--Moss’s explosive, empowering narrative is grounded in meticulous, often eye-opening research. He goes inside the labs where food scientists use cutting-edge technology to calculate the "bliss point" of sugary beverages or enhance the "mouth feel" of fat by manipulating its chemical structure. He unearths marketing techniques taken straight from tobacco company playbooks to redirect concerns about the health risks of products. He talks to concerned executives who explain that they could never produce truly healthy alternatives to their products even if serious regulation became a reality. Simply put: the industry itself would cease to exist without salt, sugar, and fat.

    It is a waste product and a commodity pricier than oil. It can save lives and transmit deadly infections. Each one of us has roughly nine pints of it, yet many don’t even know their own blood type. And for all its ubiquity, the few tablespoons of blood discharged by 800 million women are still regarded as taboo; menstruation is perhaps the single most demonized biological event.Rose George, author of The Big Necessity, is renowned for her intrepid work on topics that are invisible but vitally important. In Nine Pints, she takes us from ancient practices of bloodletting to modern “hemovigilance” teams that track blood-borne diseases. She introduces Janet Vaughan, who set up the world’s first system of mass blood donation during the Blitz, and Arunachalam Muruganantham, known as “Menstrual Man” for his work on sanitary pads for developing countries. She probes the lucrative business of plasma transfusions, in which the U.S. is known as the “OPEC of plasma.” And she looks to the future, as researchers seek to bring synthetic blood to a hospital near you.Spanning science and politics, stories and global epidemics, Nine Pints reveals our life's blood in an entirely new light.
