     This book is a supplement to What If? and intended to enhance the experience of reading the original book. We recommend purchasing the full version of What If? on Amazon in addition to this book. Introduction What If? Serious Scientific Answers to Absurd Hypothetical Questions presents a wide variety of questions covering a range of dubious potentialities and the results which would ensue should they become reality. The questions are collected from author Randall Munroe’s website, where they are sent in by readers of his blog. Some of the questions are conceptual, for example how much force would be required for Yoda to lift an X-fighter, others are in a more serious vein. All of the answers however are based on research and the application of scientific principles by the author, himself trained in physics and a former roboticist for NASA.

    We see it, touch it, and live in it every day. It is a habitat for a mesmerizingly complex world of micro-organisms and physical functions that are vital to our health and our survival. It is also a waste removal plant, a warning system for underlying disease and a dynamic immune barrier to infection. One of the first things people see about us, skin is crucial to our sense of identity, providing us with social significance and psychological meaning. And yet our skin and the fascinating way it functions is largely unknown to us. In prose as lucid as his research underlying it is rigorous, blending in memorable stories from the past and from his own medical experience, Monty Lyman has written a revelatory book exploring our outer surface that will surprise and enlighten in equal measure. Through the lenses of science, sociology, and history--on topics as diverse as the mechanics and magic of touch (how much goes on in the simple act of taking keys out of a pocket and unlocking a door is astounding), the close connection between the skin and the gut, what happens instantly when one gets a paper cut, and how a midnight snack can lead to sunburn--Lyman leads us on a journey across our most underrated and unexplored organ and reveals how our skin is far stranger, more wondrous, and more complex than we have ever imagined.

    In this groundbreaking analysis, over thirty of the most popular treatments—acupuncture, homeopathy, aromatherapy, reflexology, chiropractic, and herbal medicines—are examined for their benefits and potential dangers. Questions answered include: What works and what doesn't? What are the secrets, and what are the lies? Who can you trust, and who is ripping you off? Can science decide what is best, or do the old wives' tales really tap into ancient, superior wisdom?In their scrutiny of alternative and complementary cures, authors Simon Singh and Edzard Ernst also strive to reassert the primacy of the scientific method as a means for determining public health practice and policy.

    We all have one, but most of us will never see one. The heart surgeon now has that privilege but, for centuries, the heart was out of reach even for surgeons. So when a surgeon nowadays opens up a ribcage and mends a heart, it remains something of a miracle, even if, to some, it is merely plumbing. As with plumbers, the quality of surgeons’ work varies. As with plumbers, surgeons’ opinion of their own prowess and their own attitude to risk are not always reliable. Measurement is key. We’ve had a century of effective evidence-based medicine. We’ve had barely a decade of thorough monitoring of clinical outcomes. Thanks to the ground-breaking risk modelling of pioneering surgeons like Samer Nashef, we at last know how to judge whether an operation is in a patient’s best interest, which hospital and surgeon would be best for that operation, when it might best be performed and what the exact level of risk is. We have at last made what is important in surgery measurable. But how should surgeons, and their patients, use these newfound insights? Ever since his days as a medical student, Samer Nashef has challenged the medical profession to be more open and more accurate about the success of surgical procedures, for the sake of the patients. In The Naked Surgeon, he unclothes his own profession to demonstrate to his reader (and prospective patient) many revelations, such as the paradox at the heart of the cardiac surgeon’s craft: the more an operation is likely to kill you, the better it is for you. And he does so with absolute clarity, fluency and not a little wit.

    Thanks to the astonishing results it provides--glowing skin, a flatter stomach, enhanced immunity, and full-body detox--the practice of manually stimulating the lymphatic system has become one of the most popular wellness practices today. Lymphatic drainage works because the lymphatic system--a complex geography of rivers that snake throughout the body just beneath the surface of the skin--connects every other bodily system. When lymph flows, everything else flows, too.In this first-of-its-kind guide, veteran lymphatic drainage practitioner, educator, and advocate Lisa Levitt Gainsley explains how to maintain lymphatic health, sharing the five-minute self-massage techniques she originally developed for her high-powered Los Angeles clientele. These simple sequences are tailored to address a number of specific and common issues: bloating, headaches, digestive problems, immune health, anxiety, weight loss, acne, inflammation, and more.Whether you just want to look and feel your best or are facing a more serious health issue such as cancer treatment or recovery, The Book of Lymph offers educational and practical instruction to help you cultivate a body free of pain and lethargy, activate a calmer state of being, and boost overall glow--in just five minutes a day.

    But things didn't turn out that way. For a start, we turned out to have far fewer genes than originally thought - just over 20,000, the same sort of number as a fruit fly or worm. What's more, the proportionof DNA consisting of genes coding for proteins was a mere 2%. So, was the rest of the genome accumulated 'junk'?Things have changed since those early heady days of the Human Genome Project. But the emerging picture is if anything far more exciting. In this book, John Parrington explains the key features that are coming to light - some, such as the results of the international ENCODE programme, still much debated and controversial in their scope. He gives an outline of the deeper genome, involving layers of regulatory elements controlling and coordinating the switching on and off of genes; the impact ofits 3D geometry; the discovery of a variety of new RNAs playing critical roles; the epigenetic changes influenced by the environment and life experiences that can make identical twins different and be passed on to the next generation; and the clues coming out of comparisons with the genomes ofNeanderthals as well as that of chimps about the development our species. We are learning more about ourselves, and about the genetic aspects of many diseases. But in its complexity, flexibility, and ability to respond to environmental cues, the human genome is proving to be far more subtle than we ever imagined.

    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.
