The knowledge of death is so terrifying that we live most of our lives in denial of it. One of the most difficult moments of childhood must be when each of us first realizes that not only we but all our loved ones will die—and there is nothing we can do about it. Or at least, there hasn’t been. Today, we are living through a revolution in biology. Giant strides are being made in understanding why we age—and why some species live longer than others. Could we eventually cheat disease and death and live for a very long time, possibly many times our current lifespan?

Aging - not cancer, not heart disease - is the underlying cause of most human death and suffering. The same cascade of biological changes that renders us wrinkled and gray also opens the door to dementia and disease. We work furiously to conquer each individual disease, but we never think to ask: Is aging itself necessary? Nature tells us it is not: There are tortoises and salamanders who are spry into old age and whose risk of dying is the same no matter how old they are.

When Dr. Michael Greger, founder of NutritionFacts.org, dove into the top peer-reviewed anti-aging medical research, he realized that diet could regulate every one of the most promising strategies for combating the effects of aging. We don’t need Big Pharma to keep us feeling young—we already have the tools. In How Not to Age, the internationally renowned physician and nutritionist breaks down the science of aging and chronic illness and explains how to help avoid the diseases most commonly encountered in our journeys through life.

Leading futurist and OneShared.World founder Jamie Metzl explores how genome sequencing, gene editing, artificial intelligence, and other technologies are not only changing our lives, but catalyzing each other in radical and accelerating ways. These technologies have the potential to improve our health, feed billions of people, supercharge our economies, and store essential information for millions of years, but can also—if we are not careful—do immeasurable harm.

While cells are commonly considered the building block of living things, it is actually the communication between cells that brings us to life, controlling our bodies and brains, determining whether we are healthy or sick, and directly influencing how we think, feel, and behave. In The Secret Language of Cells, doctor and neuroscientist Jon Lieff lets us listen in on these conversations, and reveals their significance for everything from mental health to cancer.

A long life in a healthy, vigorous, youthful body has always been one of humanity's greatest dreams. Recent progress in genetic manipulations and calorie-restricted diets in laboratory animals hold forth the promise that someday science will enable us to exert total control over our own biological aging.

True Age introduces listeners to the latest developments in the science of aging and longevity. It provides an in-depth understanding of biological age and the methods now available to estimate our own. It helps us target an individualized plan to eat, exercise, and sleep, as well as pointing to other lifestyle practices like intermittent fasting and caloric restriction that have been shown to slow or reverse the aging process.

In Mitochondria and the Future of Medicine, naturopathic doctor Lee Know tells the epic story of mitochondria - the widely misunderstood and often-overlooked powerhouses of our cells. The legendary saga began over two billion years ago, when one bacterium entered another without being digested, which would evolve to create the first mitochondrion. Since then, for life to exist beyond single-celled bacteria, it's the mitochondria that have been responsible for this life-giving energy.

In this landmark book of popular science, Daniel E. Lieberman - chair of the department of human evolutionary biology at Harvard University and a leader in the field - gives us a lucid and engaging account of how the human body evolved over millions of years, even as it shows how the increasing disparity between the jumble of adaptations in our Stone Age bodies and advancements in the modern world is occasioning this paradox: greater longevity but increased chronic disease.

Scientists are learning more and more about how brain activity controls behavior and how neural circuits weigh alternatives and initiate actions. As we probe ever deeper into the mechanics of decision making, many conclude that agency—or free will—is an illusion. In Free Agents, leading neuroscientist Kevin Mitchell presents a wealth of evidence to the contrary, arguing that we are not mere machines responding to physical forces but agents acting with purpose.

The United States spends an excess $1.5 trillion annually on health care compared to other wealthy countries—yet the amount of time that Americans live in good health ranks a lowly 68th in the world. At the heart of the problem is Big Pharma, which funds most clinical trials and therefore controls the research agenda, withholds the real data from those trials as corporate secrets, and shapes most of the information relied upon by health care professionals.

Breakthroughs in cutting-edge longevity, regenerative, and performance, science and technology are making it possible to experience vitality, resilience, and the joy of youthfulness for the duration of your lifetime. We have grown up in a culture that has normalized aging. For generations, we have dreaded and feared growing older and losing our abilities and independence but we saw no other option.

How do some people avoid the slowing down, deteriorating, and weakening that plagues many of their peers decades earlier? Are they just lucky? Or do they know something the rest of us don’t? Is it possible to grow older without getting sicker? What if you could look and feel 50 through your 80s and 90s? Founder of the Institute for Aging Research at the Albert Einstein College of Medicine and one of the leading pioneers of longevity research, Dr. Nir Barzilai’s life’s work is tackling the challenges of aging to delay and prevent the onset of all age-related diseases.

Chronic fatigue, burnout, brain fog-no matter what we call it, our constant feeling of being drained affects all that we hold dear. But the very real culprits of our fatigue don't lie in our preconceived notions of caffeine intake or adrenal fatigue, nor does the replenishment of our energy lie in overhauling our lifestyle in time-consuming and unrealistic ways. Instead, the core underlying cause lies in our cells, specifically our mitochondrial deficiency, and the solution can be found in simple, straightforward, nutritional strategies that address our body's biology.

A masterful synchronization of history and cutting-edge science shines new light on humanity's darkest diagnosis. In the wake of the Cancer Genome Atlas project's failure to provide a legible road map to a cure for cancer, science writer Travis Christofferson illuminates a promising blend of old and new perspectives on the disease.
