Locked inside the DNA of every species that ever lived are endless stories - about origins, ancestors, fate, and much more. Until recently, these secrets were completely inaccessible. But with the help of new technologies, scientists are now reading the hidden history of DNA, making remarkable discoveries about ourselves and our fellow species. Your gateway to this treasure trove of information is Unlocking the Hidden History of DNA, 12 informative and accessible lectures delivered by New York Times best-selling author Sam Kean.

Epigenetics is the science of living DNA, charting the chemical pathways that spur DNA into action by turning genes on and off. While the Human Genome Project of the early 2000s was hailed as the key to understanding human heredity and disease, that historic effort was just the beginning. It has taken epigenetics to fill in the picture, explaining how the fixed code of our genome is implemented in countless living processes.

Charles Darwin's theory of organic evolution-the idea that life on earth is the product of purely natural causes, not the hand of God-set off shock waves that continue to reverberate through Western society, and especially the United States. What makes evolution such a profoundly provocative concept, so convincing to most scientists, yet so socially and politically divisive? These 12 eye-opening lectures are an examination of the varied elements that so often make this science the object of strong sentiments and heated debate.

Cutting-edge research on the brain's interaction with the body shows that health is directly impacted by our social environments, socioeconomic status, culture, behaviors, relationships, psychological states, and habits of mind, among many factors. Mind-body medicine-working in partnership with traditional medical practice-uses a large range of psychological, physical, and behavioral treatments in a model of health care that aims to treat the whole human being.

In many ways, insects are just like us. Elaborate mating rituals, a variety of parenting styles, and a plethora of careers — from architects and engineers, to farmers and ranchers. Like us, they’re able to share complex information essential for survival, significantly impact their environment, and recycle. But insects outdo us in so many respects. They are terrestrial, but some can live underwater.

We're all getting older every day, and scientific research has shown that starting in our 20s, some brain functions begin a linear decline. But is old age all doom and gloom? Not at all! While it's true that some functions in the aging brain decline, neuroscientists have discovered that many other brain functions remain stable - or even improve - as we age.

In this series of 24 fascinating lectures, an acclaimed teacher and psychologist gives you a bio-psychological perspective on both the way we humans navigate and react to the world around us and an understanding of the ways in which that process is ever-changing.

Since the publication in 1859 of Charles Darwin's remarkable On the Origin of Species, the modern science of biology and genetics has added surprising new dimensions to evolutionary theory. In this course, you’ll discover what Darwin didn’t know, covering much of the curriculum of an introductory college course in evolutionary biology. No background in science is needed to follow these engaging lectures, delivered by Professor Scott Solomon of Rice University, a gifted teacher and widely traveled field biologist.

Your professor is Princeton University biologist Lee M. Silver, an acclaimed teacher, scientist, and author of popular books on biotechnology, genetics, and their impact on society.

No feature of the mind is as important, controversial, and mysterious as intelligence. It is the epitome of brain function, and it has a powerful influence on success in life. Now in The Intelligent Brain, taught by one of the world’s foremost researchers on intelligence, Professor Richard J. Haier of the University of California, Irvine, you’ll trace the fascinating history of intelligence testing and its leading thinkers, as well as what brain imaging studies and the most recent research findings reveal about this most complex of human phenomena.

Trying to understand our human origins has always been a fundamental part of who we are. Today, with the help of dramatic archaeological discoveries and groundbreaking advancements in technology and scientific understanding, we are closer than we've ever been to learning the true story. In recent decades, it has been the science of paleoanthropology that has led the investigation, helping us make sense of this controversial subject and providing us with a richer understanding of our origins.

An invisible world of astonishing complexity is all around you. A world so small you can’t see it with the naked eye. A world so crowded that its population staggers the mind. A world in which you participate every day - often without even knowing it. The inhabitants of this world are trillions of bacteria, viruses, fungi, and other organisms, collectively known as microbes. Hundreds of thousands could fit on the period at the end of this sentence. And many play a powerful role in your life.

Considering everything the brain does, how can it possibly be the source of our personalities, dreams, thoughts, sensations, utterances, and movements? Understanding the Brain, a 36-lecture course by award-winning Professor Jeanette Norden of Vanderbilt University, takes you inside this astonishingly complex organ and shows you how it works. With its combination of neurology, biology, and psychology, this course helps you understand how we perceive the world through our senses, how we move, how we learn and remember, and how emotions affect our thoughts and actions.

Right this minute, your body is carrying roughly 38 trillion microbial cells along with it—and in the vast majority of cases, you couldn’t live without them. On top of that, you harbor around 380 trillion viruses, most of which are either beneficial or benign. The Hidden Power of Microbes draws back the curtain on this vast microworld in 24 half-hour lectures delivered by acclaimed science communicator Dr. Melissa Booth, research scientist, professor, and Founder and Principal of The Science Communicator, devoted to training scientists to tell accurate, compelling stories about their fields.

“Who are you?” Chances are you’d answer this question by describing the highlights of your personality and life experiences. But if you’d been asked this same question yesterday, you might have responded with a slightly different description. Does that mean you are a particular person today but were a different person yesterday? And what about tomorrow? Welcome to the slippery, shape-shifting nature of memory. As Professor Gabrielle Principe reveals, “you” are the conglomeration of the often-unreliable information your brain decides to feed you at any given moment.

This 24-lecture series is your guide to the latest information and viewpoints on what scientists know about this fascinating subject. Taught by an award-winning teacher whose training as a clinical psychologist straddles both the science of the mind and its impact on individual lives, their comprehensive approach reveals how that science applies to the life of our species - and to your own life as well. The lectures explore theories about how the mind works on both an evolutionary and individual scale.

The year is 8000 B.C. A man wanders across a field of prairie grasses in search of edible berries and roots and wild game to feed his family. As he walks, the tips of the grasses brush against him, releasing seeds. He collects a few of these seeds and brings them back to his camp. Later, he notices that when they fall on earth, they begin to sprout, and a new plant grows. In small moments like these, the path of Homo sapiens is changed forever.
