Could extinct species, like mammoths and passenger pigeons, be brought back to life? The science says yes. In How to Clone a Mammoth, Beth Shapiro, evolutionary biologist and pioneer in "ancient DNA" research, walks listeners through the astonishing and controversial process of de-extinction.

Are stars like Usain Bolt, Michael Phelps, and Serena Williams genetic freaks put on Earth to dominate their respective sports? Or are they simply normal people who overcame their biological limits through sheer force of will and obsessive training? In this controversial and engaging exploration of athletic success, Sports Illustrated senior writer David Epstein tackles the great nature vs. nurture debate and traces how far science has come in solving this great riddle.

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.

Racist pseudoscience is on the rise - fueling hatred, feeding nationalism, and seeping into our discourse on everything from sports to intelligence. Even the well-intentioned repeat stereotypes based on "science", because cutting-edge genetics are hard to grasp - and all too easy to distort. Paradoxically, misconceptions are multiplying amid today's unprecedented surge of research on human genetics. We've never had a clearer picture of who we are and where we come from, and the science, when accurately understood, is a powerful and definitive ally against racism.

As the planet emerged from the last ice age, a language was born between Europe and Asia, by the Black Sea. This ancient tongue, which we call Proto-Indo-European, soon exploded out of its cradle, changing and fragmenting as it went, until its offspring were spoken from Scotland to China. Today those descendants constitute the world’s largest language family, the thread that connects disparate cultures: Dante’s Inferno to the Rig Veda, The Lord of the Rings to the love poetry of Rumi. Indo-European languages are spoken by nearly half of humanity. How did this happen?

Named one of the top books of 2009 by the Times Literary Supplement (London), this controversial and compelling audiobook from Dr. Stephen C. Meyer presents a convincing new case for intelligent design (ID) based on revolutionary discoveries in science and DNA. Along the way Meyer argues that Charles Darwin's theory of evolution as expounded in The Origin of Species did not, in fact, refute ID.

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.

Does losing weight and staying healthy feel like a battle? Well, it's really a war. Your enemies are your own genes, backed by millions of years of evolution, and the only way to win is to outsmart them. From the renowned surgeon and founder of Gundry MD, this revolutionary book shares the health secrets other doctors won't tell you.

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.

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.

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.

When we think of the forces driving cancer, we don’t necessarily think of evolution. But evolution and cancer are closely linked, for the historical processes that created life also created cancer. The Cheating Cell delves into this extraordinary relationship, and shows that by understanding cancer’s evolutionary origins, researchers can come up with more effective, revolutionary treatments.

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.

Until very recently, if you were to ask most doctors, they would tell you there were only two kinds of medicine: the quack kind, and the evidence-based kind. The former is baseless, and the latter based on the best information human effort could buy. Well, Eric Topol isn't most doctors, and he suggests you entertain the notion of a third kind of medicine, one that will make the evidence-based state-of-the-art stuff look scarcely better than an alchemist trying to animate a homunculus in a jar.

Shortly before his father's death, Lennard Davis received a cryptic call from his uncle Abie, who said he had a secret he wanted to tell him one day. When finally revealed, the secret - that Abie himself was Davis's father, via donor insemination - seemed too preposterous to be true. Born in 1949, Davis wasn't even sure that artificial insemination had existed at that time. Moreover, his uncle was mentally unstable, an unreliable witness to the past. Davis tried to erase the whole episode from his mind.

Around 250,000 people have had their genomes sequenced, and scientists expect that number to rise to one billion by 2025. Professor Steven J. Heine argues that the first thing we will do on receiving our DNA test results is to misinterpret them completely. Despite breathless (often lightly researched) media coverage about newly discovered "cancer" or "divorce" or "IQ" genes, the prospect of a DNA test forecasting how your life is going to turn out is vanishingly small.

For decades after the identification of the structure of DNA, scientists focused only on genes, the regions of the genome that contain codes for the production of proteins. Other regions that make up 98 percent of the human genome were dismissed as "junk," sequences that serve no purpose. But researchers have recently discovered variations and modulations in this junk DNA that are involved with a number of intractable diseases. Junk DNA can play vital and unanticipated roles in the control of gene expression, from fine-tuning individual genes to switching off entire chromosomes.

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.
