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.

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).

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.

Ancestor Trouble is one writer’s attempt to use genealogy - a once-niche hobby that has grown into a multi-billion-dollar industry - to expose the secrets and contradictions of her own ancestors, and to argue for the transformational possibilities that reckoning with our ancestors offers all of us.

With so much variation that can be handed down genetically, for better or worse, the way we understand our biology holds huge importance for how we understand our world and one another, including the biggest questions of our day, such as social inequality. Eye-opening and profound, Adaptable is a revolutionary reappraisal of an overlooked science.

Experts agree on the value of genetic testing when there is a family history of disease, or if the patient has an illness frequently caused by a mutation. Knowing the disease mutation lets family members find out if they have it too and need preventive care. The book explains that doctors can order tests with genetic counseling at relatively low cost and how this will help them prescribe preventive actions, make earlier diagnoses, and get better outcomes.

The Ancestor's Tale is a pilgrimage back through time - a journey on which we meet up with fellow pilgrims as we and they converge on our common ancestors. Chimpanzees join us at about six million years in the past, gorillas at seven million years, orangutans at 14 million years, as we stride on together, a growing band. The journey provides the setting for a collection of some 40 tales.

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.

Short, sassy, and bold, Mean Genes reveals that our struggles for self-improvement are, in fact, battles against our own genes - genes that helped our distant ancestors flourish, but are selfish and out of place in the modern world.

Origin is the story of who the first peoples in the Americas were, how and why they made the crossing, how they dispersed south, and how they lived based on a new and powerful kind of evidence: their complete genomes. Origin provides an overview of these new histories throughout North and South America, and a glimpse into how the tools of genetics reveal details about human history and evolution.

In November 1987, a young couple on an overnight trip to Seattle vanished without a trace. A week later, the bodies of Tanya Van Cuylenborg and her boyfriend Jay Cook were found in rural Washington. It was a brutal crime, and it was the perfect crime: With few clues and no witnesses, an international manhunt turned up empty, and the sensational case that shocked the Pacific Northwest gradually slipped from the headlines.

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.

Nuestro código genético, el ADN, es la información más íntima y profunda que heredamos de nuestros padres y antepasados. Es, además, casi igual entre los seres humanos. Podríamos decir que solo una porción minúscula es responsable de que podamos ver tantas diferencias a simple vista: color de ojos, de piel, de pelo, de altura. Pero ese mínimo porcentaje es también el que nos puede brindar datos esenciales para saber qué alimentos consumir para mejorar nuestra calidad de vida y prolongarla.

She Has Her Mother's Laugh presents a profoundly original perspective on what we pass along from generation to generation. Charles Darwin played a crucial part in turning heredity into a scientific question, and yet he failed spectacularly to answer it. The birth of genetics in the early 1900s seemed to do precisely that. Gradually, people translated their old notions about heredity into a language of genes. We need a new definition of what heredity is and, through Carl Zimmer's lucid exposition and storytelling, this resounding tour de force delivers it.

World renowned scientist Carl Sagan and acclaimed author Ann Druyan have written a Roots for the human species, a lucid and riveting account of how humans got to be the way we are. It shows with humor and drama that many of our key traits - self-awareness, technology, family ties, submission to authority, hatred for those a little different from ourselves, reason, and ethics - are rooted in the deep past, and illuminated by our kinship with other animals.

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.

A scientific and medical revolution has crept up on us, based on study after study, from hundreds of laboratories around the world. It is no longer just a theoretical shift: every one of us will be touched by it, and many of us already have been. The meaning of disease, our understanding of the human body, and crucial decisions about what we all need to know and what choices we make about our health are at stake. Welcome to the new world of personalized medicine.

An almost limitless archive of our history lies hidden inside our bodies, and this book traces the ancient story of Scotland from that scientific viewpoint. The mushrooming of genetic studies, of DNA analysis, is rewriting history in spectacular fashion. In Scotland: A Genetic Journey, Alistair Moffat explores the history that is printed on our genes, and in a remarkable new approach, uncovers the detail of where Scots are from, where they have journeyed, and who they are - and in so doing, vividly colors in a DNA map of Scotland.

With rapid advances in genomic technologies, genetic testing has become a key part of both clinical practice and research. Scientists are constantly discovering more about how genetics plays a role in health and disease, and healthcare providers are using this information to more accurately identify their patients' particular medical needs. Genetic information is also increasingly being used for a wide range of non-clinical purposes, such as exploring one's ancestry.

Sociogenomics brings together advances in molecular genetics and traditional social and behavioral science. The key tool is the polygenic index, which allows us to analyze DNA to measure a child's genetic potential. Today, we can estimate a child's adult height, how far they will go in school, and their weight as an adult—all from a cheek swab, finger prick, or vial of saliva. Dalton Conley and other researchers are using this new science to shed light on the ways in which genes shape our world, influencing how each person both creates and responds to the environment around them.
