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.

L'opera che proponiamo all'ascolto è fondamentale - secondo l'autorevole rivista "Science" - per chi vuole cominciare a capire il rapporto fra il nostro patrimonio genetico e la storia delle civiltà. Come e da dove ebbero origine le diverse popolazioni umane? Quali percorsi seguirono via via che si distribuivano nei vari continenti, si differenziavano fra loro e si moltiplicavano? Che ruolo ha avuto l'evoluzione culturale e tecnologica? Quali e quante lingue sono parlate al mondo? Esistono veramente le 'razze' umane? A queste, e a molte altre domande, affascinanti e grandiose, offre una risposta un'opera che fin dalla sua prima pubblicazione in USA nel 1994 (la versione italiana è di Adelphi, 1997) è stata definita un caposaldo della ricerca.

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.

What is life? Humans have been asking this question for thousands of years. But as technology has advanced and our understanding of biology has deepened, the answer has evolved. For decades, scientists have been exploring the limits of nature by modifying and manipulating DNA, cells, and whole organisms to create new ones that could never have previously existed on their own.

While we joke that men are from Mars and women are from Venus, our gender differences can't compare to those of other animals. For instance: the male garden spider spontaneously dies after mating with a female more than fifty times his size. Female cichlids must guard their eggs and larvae--even from the hungry appetites of their own partners. And male blanket octopuses employ a copulatory arm longer than their own bodies to mate with females that outweigh them by four orders of magnitude. Why do these gender gulfs exist?

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).

John Tyler Bonner, one of our most distinguished and insightful biologists, here challenges a central tenet of evolutionary biology. In this concise, elegantly written book, he makes the bold and provocative claim that some biological diversity may be explained by something other than natural selection. With his customary wit and accessible style, Bonner makes an argument for the underappreciated role that randomness - or chance - plays in evolution.

Most people know that Gregor Mendel, the Moravian monk who patiently grew his peas in a monastery garden, shaped our understanding of inheritance. But people might not know that Mendel's work was ignored in his own lifetime, even though it contained answers to the most pressing questions raised by Charles Darwin's revolutionary book, On Origrin of the Species, published only a few years earlier. Mendel's single chance of recognition failed utterly, and he died a lonely and disappointed man.

One in 3,000 people is born with neurofibromatosis. It affects all of them in different ways. For some, neurofibromatosis is as clear as the tumors on their face. For others, it hides beneath the surface, creating tumors that destroy hearing, vision, and more. Many of them are misdiagnosed, misunderstood, and often simply missed by a world of medicine that doesn't have a full grasp on all the effects of NF.

From New York Times bestselling author Sam Kean comes incredible stories of science, history, language, and music, as told by our own DNA. In The Disappearing Spoon, bestselling author Sam Kean unlocked the mysteries of the periodic table. In The Violinist's Thumb, he explores the wonders of the...

Having worked on numerous high-profile genetic investigations, including one focused on the famed Iceman of the Italian Alps, Bryan Sykes has become a premier authority on human genetics. In DNA USA, Sykes examines the unique fabric of the population of the United States - one of the world’s most genetically variegated countries. His fascinating discoveries offer new insights into the biological profile of the great melting pot.

The Development of an Extraordinary Species We human beings share 98 percent of our genes with chimpanzees. Yet humans are the dominant species on the planet -- having founded civilizations and religions, developed intricate and diverse forms of communication, learned science, built cities, and...

Again and again, microbes have shaped our health, our genetics, our history, our culture, our politics, even our religion and ethics. This book reveals much that scientists and cultural historians have learned about the pervasive interconnections between infectious microbes and humans. It also considers what our ongoing fundamental relationship with infectious microbes might mean for the future of the human species.

Human beings have astonishing genetic vulnerabilities. More than half of us will die from complex diseases that trace directly to those vulnerabilities, and the modern world we've created places us at unprecedented risk from them. In It Takes a Genome, Greg Gibson posits a revolutionary new hypothesis: Our genome is out of equilibrium, both with itself and its environment. Simply put, our genes aren't coping well with modern culture.

By identifying the structure of DNA, the molecule of life, Francis Crick and James Watson revolutionized biochemistry and won themselves a Nobel Prize. At the time, Watson was only 24, a young scientist hungry to make his mark. His uncompromisingly honest account of the heady days of their thrilling sprint against other world-class researchers to solve one of science's greatest mysteries gives a dazzlingly clear picture of a world of brilliant scientists with great gifts, very human ambitions, and bitter rivalries.

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, which will revolutionize medicine and change the way we think about and treat disease.

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.

Richard Dawkins' brilliant reformulation of the theory of natural selection has the rare distinction of having provoked as much excitement and interest outside the scientific community as within it. His theories have helped change the whole nature of the study of social biology, and have forced thousands to rethink their beliefs about life.

“Ridley leaps from chromosome to chromosome in a handy summation of our ever increasing understanding of the roles that genes play in disease, behavior, sexual differences, and even intelligence. . . . . He addresses not only the ethical quandaries faced by contemporary scientists but the...

Despite extensive evidence highlighting the influence of genetics in the business world, this critical connection has been glossed over by corporate leaders and management gurus. Now, for the first time, author Scott Shane explains why genes matter, and how an understanding of their relationship to behavior is of vital importance to employers, employees, and policy makers.
