A tiny mutation on the X chromosome can shape a family’s history. Passed down from a “carrier” parent to a child, fragile X syndrome is the most common inherited cause of intellectual disability and autism. Beyond that—and a rarity among genetic disorders—some fragile X carriers not only transmit the mutation, but also experience related conditions themselves.

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?

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).

In a first-person narrative of scientific discovery that opens new perspectives on biology, anthropology, and the limits of rationalism, The Cosmic Serpent reveals how startlingly different the world around us appears when we open our minds to it.

WASPs finally get their due in this stimulating history by one of the world's leading geneticists. Saxons, Vikings, and Celts is the most illuminating book yet to be written about the genetic history of Britain and Ireland. Through a systematic, ten-year DNA survey of more than 10,000 volunteers, Bryan Sykes has traced the true genetic makeup of British Islanders and their descendants.

Just in the last three years a flood of new scientific findings, driven by revelations discovered in the human genome, has provided compelling new answers to many long-standing mysteries about our most ancient ancestors, the people who first evolved in Africa and then went on to colonize the whole world. Nicholas Wade weaves this host of news-making findings together for the first time into an intriguing new history of the human story before the dawn of civilization.

The Gene is the story of one of the most powerful and dangerous ideas in our history, from best-selling, prize-winning author Siddhartha Mukherjee. Spanning the globe and several centuries, The Gene is the story of the quest to decipher the master code that makes and defines humans, that governs our form and function. The story of the gene begins in an obscure Augustinian abbey in Moravia in 1856, where a monk stumbles on the idea of a 'unit of heredity'.

Scientists' understanding of life is progressing more rapidly than at any point in human history, from the extraordinary decoding of DNA to the controversial emergence of biotechnology. Featuring pioneering biologists, geneticists, physicists, and science writers, Life explains just how far we've come - and takes a brilliantly educated guess at where we're heading.

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.

In Regenesis, George Church and science writer Ed Regis explore the possibilities of the emerging field of synthetic biology. Synthetic biology, in which living organisms are selectively altered by modifying substantial portions of their genomes, allows for the creation of entirely new species of organisms. These technologies - far from the out-of-control nightmare depicted in science fiction - have the power to improve human and animal health, increase our intelligence, enhance our memory, and even extend our life span.

DNA is the genetic material that defines us as individuals. Over the last two decades, it has emerged as a powerful tool for solving crimes and determining guilt and innocence. But, very recently, an important new aspect of DNA has been revealed: it contains a detailed record of evolution. That is, DNA is a living chronicle of how the marvelous creatures that inhabit our planet have adapted to its many environments, from the freezing waters of the Antarctic to the lush canopy of the rain forest.

Epigenetics can potentially revolutionize our understanding of the structure and behavior of biological life on Earth. It explains why mapping an organism's genetic code is not enough to determine how it develops or acts and shows how nurture combines with nature to engineer biological diversity. Surveying the 20-year history of the field while also highlighting its latest findings and innovations, this volume provides a readily understandable introduction to the foundations of epigenetics.

Each of us began life as a single cell. From this humble origin, we embarked on a risky journey fraught with opportunities for disaster. Yet, amazingly, we reached our destination intact, emerging as dazzlingly complex, exquisitely engineered assemblages of trillions of cells. This metamorphosis constitutes one of nature's most spectacular yet commonplace magic tricks—and one of its most coveted secrets. In From One Cell, physician and researcher Ben Stanger offers a glimpse into what scientists are discovering about how life and the body take shape.

Engrossing and captivating, Editing Humanity takes listeners inside the fascinating world of a new gene editing technology called CRISPR, a high-powered genetic toolkit that enables scientists to not only engineer but to edit the DNA of any organism down to the individual building blocks of the genetic code. Davies introduces listeners to arguably the most profound scientific breakthrough of our time. He tracks the scientists on the front lines of its research to the patients whose powerful stories bring the narrative movingly to human scale.

Genetic engineering, which refers to the direct manipulation of DNA, became a reality in the 1970s.

The burgeoning new science of epigenetics offers a cornucopia of insights - some comforting, some frightening. For example, the male fetus may be especially vulnerable to certain common chemicals in our environment, in ways that damage not only his own sperm but also the sperm of his sons. And it’s epigenetics that causes identical twins to vary widely in their susceptibility to dementia and cancer. But here’s the good news: unlike mutations, epigenetic effects are reversible. Indeed, epigenetic engineering is the future of medicine.

Stepping effortlessly from myth to cutting-edge science, Mutants gives a brilliant narrative account of our genetic code and the captivating people whose bodies have revealed it - a French convent girl who found herself changing sex at puberty; children who, echoing Homer's Cyclops, are born with a single eye in the middle of their foreheads; a village of long-lived Croatian dwarves; one family, whose bodies were entirely covered with hair, was kept at the Burmese royal court for four generations and gave Darwin one of his keenest insights into heredity.
