Whatever your views on climate change, it's important to understand how the current scientific consensus on global warming evolved out of basic physical principles and a broad range of observations. This lucid series of 12 lectures is designed to do exactly that-reviewing the most up-to-date research and explaining the concepts, tools, data, and analysis that have led an overwhelming number of climate scientists to conclude that Earth is indeed warming and that we humans are in great part responsible.

The landscape of cancer treatment and prevention is a vastly different place than it was even a decade ago. 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.

Thanks to an ongoing revolution in the science of meteorology, we can now understand how extreme weather conditions arise, produce far more accurate forecasts, and know how to protect ourselves when dangerous conditions develop. The Science of Extreme Weather is your field guide to the worst that Earth’s atmosphere can inflict. In 24 exciting, informative, and potentially life-saving half-hour lectures aimed at weather novices and amateur forecasters alike, you gain a surprisingly powerful tool in the face of such overwhelming forces: knowledge.

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.

The work of archaeology uncovers fascinating vestiges of humanity’s past, greatly enriching our knowledge of our ancestors and ourselves. Over the last century, archaeologists have increasingly ventured underwater, making spellbinding finds and opening an incredible new frontier for archaeological discovery. In the 12 delightful and eye-opening lectures of Underwater Archaeology: Mysteries of the Deep, Professor Lemke, an expert underwater archaeologist working in the field, invites you to discover astonishing treasures of history that lie beneath the waves.

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. And in recent decades, these forces have evolved and developed at a lightning-fast pace. 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.

In 24 thought-provoking lectures designed for nonscientists, this course explores today's exciting field of genomics, the study of the vast storehouse of information contained within chromosomes. 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.

Synthetic Biology: Life’s Extraordinary New Worlds is an introduction to synthetic biology for non-scientists, covering the exciting field that is transforming health care, agriculture, environmental science, and many other areas. Using the molecules of life to answer scientific questions and manipulate life for human benefit, synthetic biology encompasses a wide range of applications—from gene editing and metabolic engineering to food synthesis and green technologies.

Great Heroes and Discoveries of Astronomy takes you around the world and across time in search of the unsung heroes who, in many ways, are just as important to the story of astronomy as Hubble, Einstein, and Sagan. Whether they stood on the shoulders of giants or themselves offered shoulders for giants to stand on, the heroes of astronomy you’ll meet in these 24 lessons are a collective of the brightest and most daring minds in science.

Today, with relatively easy access to our DNA ancestry, we have more data about ourselves and family history than previous generations could have imagined. In the 12 fascinating lessons of Identity in the Age of Ancestral DNA, Anita Foeman, PhD, professor of communication and media, and founder and primary investigator of the DNA Discussion Project at West Chester University, takes us behind the scenes to examine what really happens when individuals receive their personal DNA ancestry results.

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.

We’re living in a golden age of scientific breakthroughs and technological advancements. Now, you have the chance to dig into some of the most fascinating and important scientific advancements in recent years. Unexpected, consequential, and often counterintuitive, 12 Revolutionary Discoveries That Could Change Everything offers an inspiring introduction to science in the 21st century. Taught by Scientific American editor in chief Laura Helmuth, these eye-opening lectures will satiate even the most inquisitive mind.

Spaceflight is notoriously dangerous. Beyond launch mishaps and equipment failures, astronauts face serious health problems from long-term weightlessness and high-energy radiation. Not to mention, the space environment is a near-perfect vacuum that can quickly kill anyone who is unprotected. Drawing on the hard-won insights of NASA astronauts and space researchers, this 12-lecture course presents the perils of spaceflight and what experts have done to make them survivable. It also deals with livability in space, including nutrition, sleep, environmental control, and personal hygiene.
