Where did I come from? Why do I have two arms but just one head? How is my left leg the same size as my right one? Why are the fingerprints of identical twins not identical? How did my brain learn to learn? Why must I die? Questions like these remain biology's deepest and most ancient challenges. They force us to confront a fundamental biological problem: How can something as large and complex as a human body organize itself from the simplicity of a fertilized egg?

Vital research is starting to challenge long-standing assumptions about gender identity and biological sex, such as work that indicates the brain is a “mosaic” of traits rather than a “male” and “female” brain. Growing knowledge of the genetic complexities of sexual determination is changing the way the medical community treats intersex individuals, and in this audiobook, The New Science of Sex and Gender, we not only examine the latest studies in biology, medicine, and psychology but also, more importantly, their bearing on healthcare, identity, and access.

An award-winning physician and scientist makes the game-changing case that genetic females are stronger than males at every stage of life. Here are some facts: Women live longer than men. They have stronger immune systems. They're better at fighting cancer and surviving famine and even see the world in a wider variety of colours. They are simply stronger than men at every stage of life. Why is this? And why are we taught the opposite?

The science of epigenetics has been scientifically proven to give anyone the power to change the expressions of their genes. Genes can be altered by either the external environmental or internal mental and emotional signals without altering the gene sequence itself. The protocols in this book take a person through the step-by-step process of doing it. By using the detailed processes given, anyone can send new signals to their genes to produce and manufacture the different proteins to restore health, gain new strength, and extend life expectancy.

Bill McKibben, examines the dangers inherent in an array of technologies that threaten not just our survival, but our identity. Imagine a future where lab workers can reprogram human embryos to make our children "smarter" or "more sociable" or "happier." Enough examines such possibilities, and explains how we can avoid their worst consequences while still enjoying the fruits of our new scientific understandings.

Humans are primates, much like chimps—or so we've been continually told. Yet recent discoveries show that our species has a different brain design, function, and chemistry; different eating, sleeping, mating, and rearing patterns; a different metabolism; and a different physiology than apes. Nor is our behavior much like theirs, and we don't even have the feet made for climbing trees that define the primate order. Could it be that conceiving of ourselves as primates isn't helping us understand what it is to be human?

If you could bring back one living being from the whole of the history of time, what would you choose? Comedian and former stem-cell biologist Helen Pilcher has thought about this problem - a lot. In Bring Back the King, Helen explains the cutting-edge science that makes the resurrection of extinct animals a very real possibility and highlights her choices from eras gone by, from the king of the dinosaurs, Tyrannosaurus rex, to the King of Rock 'n' Roll, Elvis Presley.

Cancer has always been with us. It killed our hominid ancestors, the mammals they evolved from and the dinosaurs that trampled the ground before that. Tumours grow in pets, livestock and wild animals. Even tiny jelly-like Hydra - creatures that are little more than a tube full of water - can get cancer. Paradoxically, many of us think of cancer as a contemporary killer, a disease of our own making caused by our modern lifestyles.

In November 2018, the world was shocked to learn that two babies had been born in China with DNA edited while they were embryos - as dramatic a development in genetics as the cloning of Dolly the sheep was in 1996. In this book, Hank Greely, a leading authority on law and genetics, tells the fascinating story of this human experiment and its consequences. Greely explains what Chinese scientist He Jiankui did, how he did it, and how the public and other scientists learned about and reacted to this unprecedented genetic intervention.

The DNA Restart, by world-renowned neurogeneticist and New York Times best-selling author Dr. Sharon Moalem, walks you through revolutionary steps to a diet and lifestyle perfect for your individual genetic makeup. The DNA Restart plan utilizes decades of in-depth scientific research into genetics, epigenetics, nutrition, and longevity to explain the pivotal role genes play in the journey to ideal weight and health status.

In the early 1800s, a century before there was any concept of the gene, physicians in insane asylums began to record causes of madness in their admission books. Almost from the beginning, they pointed to heredity as the most important of these causes. As doctors and state officials steadily lost faith in the capacity of asylum care to stem the terrible increase of insanity, they began emphasizing the need to curb the reproduction of the insane. They became obsessed with identifying weak or tainted families and anticipating the outcomes of their marriages.

DNA Demystified satisfies the public appetite for and curiosity about DNA and genetics. The book begins with the basic groundwork and a brief history of DNA and genetics. Chapters then cover newsworthy topics, including DNA fingerprinting, using DNA in forensic analyses, and identifying cold-case criminals. For listeners intrigued by the proliferation of at-home DNA tests, the text includes fascinating explorations of genetic genealogy and family tree construction.

Almost daily, headlines announce newly discovered links between cancers and their genetic causes. Science journalist Jessica Wapner vividly relates the backstory behind those headlines, reconstructing the crucial breakthroughs, explaining the science behind them, and giving due to the dozens of researchers, doctors, and patients whose curiosity and determination restored the promise of a future to the more than 50,000 people diagnosed each year with chronic myeloid leukemia (CML).

What makes you the way you are - and what makes each of us different from everyone else? In Innate, leading neuroscientist and popular science blogger Kevin Mitchell traces human diversity and individual differences to their deepest level: in the wiring of our brains.

A leading brain scientist's look at the neurobiology of pleasure-and how pleasures can become addictions. Whether eating, taking drugs, engaging in sex, or doing good deeds, the pursuit of pleasure is a central drive of the human animal. In The Compass of Pleasure Johns Hopkins neuroscientist David J. Linden explains how pleasure affects us at the most fundamental level: in our brain.

In Mercies in Disguise, acclaimed New York Times reporter and best-selling author Gina Kolata tells the story of the Baxleys, an upstanding family in small-town South Carolina. Many of them were doctors, but still, they are struck down by an inscrutable illness. Finally they discover the cause of the disease after a remarkable sequence of providential events. Meanwhile science, progressing for 50 years along a parallel track, handed the Baxleys a question - not a cure but a blood test that would reveal who had the gene for the disease.

In recent years, genetic testing has become easily available to consumers across the globe, making it relatively simple to find out where your ancestors came from. But what do these test results actually tell us about ourselves? In Ancestors, Pierre Zalloua, a leading authority on population genetics, argues that these test results have led to a dangerous oversimplification of what one’s genetic heritage means. Genetic ancestry has become conflated with anthropological categories such as “origin,” “ethnicity,” and even “race” in spite of the complexities that underlie these concepts.

¿De dónde venimos? ¿Quiénes somos? ¿Adónde vamos? A estas preguntas atemporales responde el reconocido genetista Lluís Quintana-Murci, mostrando cómo el incremento del conocimiento obtenido en las pasadas décadas por la genética de poblaciones ha transformado nuestro conocimiento de la especie.

This Very Short Introduction uncovers the history of our understanding of sexual selection, from Darwin's key insights to the modern day. Considering the investment animals place on reproduction, variation in mating systems, sexual conflict, and the origin of sexual dimorphism, authors Marlene Zuk and Leigh Simmons discuss questions such as whether females can really choose between males on aesthetic grounds and how sexual conflict is resolved in different species.

A vibrant young Hispano woman, Shonnie Medina, inherits a breast-cancer mutation known as BRCA1.185delAG. It is a genetic variant characteristic of Jews. The Medinas knew they were descended from Native Americans and Spanish Catholics, but they did not know that they had Jewish ancestry as well. The mutation most likely sprang from Sephardic Jews hounded by the Spanish Inquisition. The discovery of the gene leads to a fascinating investigation of cultural history and modern genetics by Dr. Harry Ostrer and other experts on the DNA of Jewish populations.
