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.

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.

Four billion years ago, the infant Earth was a seething cauldron of erupting volcanoes, raining meteors, and hot noxious gases, totally devoid of life. But a relatively short time later-only 100 million to 200 million years-the planet was teeming with primitive organisms.What happened? Now you can find out-in a series of 24 vibrant lectures from a leader of the NASA-supported team studying the origins of life in the universe and also one of the nation's foremost science educators.

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.

This 24-lecture series is your guide to the latest information and viewpoints on what scientists know about this fascinating subject.

The lectures explore theories about how the mind works on both an evolutionary and individual scale.

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.

Understanding our humanity - the essence of who we are - is one of the deepest mysteries and biggest challenges in modern science. Why do we have bad moods? Why are we capable of having such strange dreams? How can metaphors in our language hold such sway on our actions? As we learn more about the mechanisms of human behavior through evolutionary biology, neuroscience, anthropology, and other related fields, we're discovering just how intriguing the human species is.

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.

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.

Thanks to a relatively new focus on molecular medicine, researchers are gaining a deeper understanding of the mechanisms involved in the disease, poising them on the brink of huge breakthroughs. What Science Knows About Cancer reports from the front lines of the war on cancer with a clear and scientifically precise - yet thoroughly accessible - guide to how the disease develops, thrives, and can potentially be conquered.

Published 150 years ago, Charles Darwin's On the Origin of Species - the text that introduced the world to natural selection - is among a handful of books that have changed the world. But the route to that status has been surprisingly circuitous and uncertain. Now, in 24 absorbing lectures by an award-winning teacher, you'll learn the remarkable story of Darwin's ideas, how scientists and religious leaders reacted to them, and the sea change in human thought that resulted.

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.

Science and technology are, without a doubt, two forces that will change the way you live your life in the coming months, years, and decades.

Explore the many possibilities of what your future may look like with these 24 lectures: a scientifically accurate and enlightening survey of today's most advanced research in fields such as engineering, biology, chemistry, and theoretical physics.

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.
