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.

Finally, the solution to the number-one reason we don't exercise: time. Everyone has one minute. A decade ago, Martin Gibala was a young researcher in the field of exercise physiology - with little time to exercise. That critical point in his career launched a passion for high-intensity interval training (HIIT), allowing him to stay in shape with just a few minutes of hard effort. It also prompted Gibala to conduct experiments that helped launch the exploding science of ultralow-volume exercise

A deeply panoramic tour of the night, from its brightest spots to the darkest skies we have left. A starry night is one of nature's most magical wonders. Yet in our artificially lit world, three-quarters of Americans' eyes never switch to night vision and most of us no longer experience true darkness. In The End of Night, Paul Bogard restores our awareness of the spectacularly primal, wildly dark night sky and how it has influenced the human experience across everything from science to art.

Fifty years ago, neuroscientists thought that a mature brain was fixed like a fly in amber, unable to change. Today, we know that our brains and nervous systems change throughout our lifetimes. This concept of neuroplasticity has captured the imagination of a public eager for self-improvement - and has inspired countless Internet entrepreneurs who peddle dubious "brain training" games and apps. In this book, Moheb Costandi offers a concise and engaging overview of neuroplasticity for the general listener.

The Arctic century is upon us. A great jockeying for power and influence has erupted among nations in the high north. At stake are trillions of dollars in profit or loss, US security, geopolitical influence and the fate of a fragile environment as well as the region's traditional people. As the ice melts and oil companies venture north, the polar regions may become the next Panama Canal, the next Arabian Peninsula-places on earth that remain relatively unknown in one century and become pivotal in the next.

Early birds and night owls are born, not made. Sleep patterns are the most obvious manifestation of the highly individualized biological clocks we inherit, but these clocks also regulate bodily functions from digestion to hormone levels to cognition. By understanding and respecting our internal time, we can live better.

In Faster, Higher, Stronger, veteran journalist Mark McClusky brings listeners behind the scenes with a new generation of athletes, coaches, and scientists whose accomplishments are changing our understanding of human physical achievement and completely redefining the limits of the human body.

Whether it’s brusque, convincing, fraught with emotion, or dripping with innuendo, language is fundamentally a tool for conveying meaning - a uniquely human magic trick in which you vibrate your vocal cords to make your innermost thoughts pop up in someone else’s mind. You can use it to talk about all sorts of things - from your new labradoodle puppy to the expansive gardens at Versailles, from Roger Federer’s backhand to things that don’t exist at all, like flying pigs.

In Arrival of the Fittest, renowned evolutionary biologist Andreas Wagner draws on over 15 years of research to present the missing piece in Darwin's theory. Using experimental and computational technologies that were heretofore unimagined, he has found that adaptations are not just driven by chance, but by a set of laws that allow nature to discover new molecules and mechanisms in a fraction of the time that random variation would take.

Every Wednesday, Gretchen Reynolds singlehandedly influences how millions of Americans work out. In her Phys Ed column for The New York Times, she debunks myths, spurs conversation, and creates arguments among her readers by questioning widely held beliefs about exercise. Expanding upon her popular columns, Reynolds tackles the questions we all have and (sometimes) ask about exercise.

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.

What gives the human brain the creative ability that defines us all as individuals? Although the silicon version is hard on its heels, the brain remains the most remarkable computer in existence. Leading us through cognitive theory, neuroscience and Darwinian evolution with his trademark wit and wisdom, Michael Corballis explains what we know - and don't know - about our minds. How do we know if we’re really the top dogs in brain power?

Lydia Denworth presents insights from studies of everything from at-risk kids in Head Start to noisy cocktail party conversation, from songbirds to signal processing, and from the invention of the telephone to sign language. Weaving together tales from the centuries-long quest to develop the cochlear implant and simultaneous leaps in neuroscientific knowledge against a tumultuous backdrop of identity politics, I Can Hear You Whisper shows how sound sculpts our children’s brains and the life changing consequences of that delicate process.

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.

When you are calm, your mind and body are in a state of focused awareness. You are in your “zone”, performing at your peak. Now, in A Calm Brain, Dr. Gayatri Devi shows how you can cultivate this optimal mental and physical state by tapping into your body’s hard-wired natural relaxation system. Our bodies have been trained to react to the beeps and alarms of all our different technologies, be it the ever present cell phone, an angry text message, or a frantic voicemail. The result is chronic stress. There is hope.

Consciousness is our gateway to experience: it enables us to recognize Van Gogh’s starry skies, be enraptured by Beethoven’s Fifth, and stand in awe of a snowcapped mountain. Yet consciousness is subjective, personal, and famously difficult to examine: philosophers have for centuries declared this mental entity so mysterious as to be impenetrable to science. In The Ravenous Brain, neuroscientist Daniel Bor departs sharply from this historical view, and proposes a new model for how consciousness works.

How much control do we have over love? Much less than we like to think. All that mystery, all that poetry, all those complex behaviors surrounding human bonding leading to the most life-changing decisions we’ll ever make, are unconsciously driven by a few molecules in our brains.

50 Great Myths of Human Evolution uses common misconceptions to explore basic theory and research in human evolution and strengthen critical thinking skills for lay audiences, listeners, and students. Includes myths such as: "Humans lived at the same time as dinosaurs"; "Lucy was so small because she was a child"; "Our ancestors have always made fire"; and "There is a strong relationship between brain size and intelligence."

Nearly every depressed person is assured by doctors, well-meaning friends and family, the media, and ubiquitous advertisements that the underlying problem is a chemical imbalance. Such a simple defect should be fixable, yet despite all of the resources that have been devoted to finding a pharmacological solution, depression remains stubbornly widespread. Why are we losing this fight?

Most of us think that longevity hinges on maintaining a normal Body Mass Index. But research conducted over the last decade hit the media in January with explosive news: Overweight and even moderately obese people with certain chronic diseases - from heart disease to cancer - often live longer and fare better than normal-weight individuals with the same ailments. In this groundbreaking audiobook, Carl Lavie, MD, reveals the science behind the obesity paradox and shows us how to achieve maximum health rather than minimum weight.
