- Columbia University - Virology I: How Viruses Work - Professor Vincent Racaniello, Ph.D. - Viruses aren't like bacteria and the "germs" you're used to hearing about. They behave in different ways, replicate differently, and while bacteria can be easily treated with something like antibiotics, when you have a viral infection like a cold or the flu, sometimes it's all about keeping yourself bundled up and on light duty until it runs its course and your body's immune system fights it off. Want to know how they work? This course will get into it in great detail. You'll learn how viruses propagate and how they work within a host's body and cells. You'll need some background in biology to get the most from this one.
- Georgetown University - Introduction to Bioethics - Professors Tom Beauchamp, John Keown, Rebecca Kukla, Margaret Little, Madison Powers, Karen Stohr, and Robert M. Veatch - If you've ever wondered whether or not we should clone human beings, grow organs in labs, harvest organs from condemned prisoners, augment the human genome, or augment the human body, you've thought about topics in bioethics.

Social Sciences, Classics and Humanities
- The Hebrew University of Jerusalem - A Brief History of Humankind - Dr. Yuval Noah Harari - This course starts in the stone age with an overview of the various human species of the time and then progresses all the way through history to the technological revolutions of the 21st century. Along the way you'll discuss topics like how humanity came to be the dominant species on the planet, why empires were so common in historical civilisations, how gender played a role in historical societies, whether or not progress meant happiness in the cultures of the past (and the present), and where we'll likely go from here.
- Harvard University - Unlocking the Immunity to Change: A New Approach to Personal Improvement - Professors Robert Kegan and Lisa Lahey - If you're reading Lifehacker, you've probably struggled with a goal or personal desire for change that just never seems to really manifest, even though you've tried. This course will help you understand why human beings are so resistant to change, why making significant changes in our lives is so incredibly difficult, and how to apply the lessons you'll learn to your own personal goals. You'll learn about new research that will help you unlock your own potential for change and overcome some of the psychological roadblocks that keep us stuck in our old routines and ruts.
- Curtis Institute of Music - Exploring Beethoven's Piano Sonatas - Professor Jonathan Biss - This series of lectures will help you explore and listen to Beethoven's piano sonatas in a new light, and take away an understanding of the time and place in which they were composed.

You'll understand why many musicians see Beethoven as the pinnacle of musical construction.
- Wellesley - Was Alexander Great? The Life, Leadership, and Legacies of History's Greatest Warrior - Professor Guy MacLean Rogers - Alexander The Great is one of the most larger-than-life figures in human history, but what was his real story? His empire stretched across most of Europe and much of Asia, and many people considered him a god, and that was all before he turned 33 years old. What made him such a force in the ancient world, and what can we learn from him today? This course explores all of those topics, including some controversial ones involving the history of warfare, human sexuality, and historical relations between the east and west as a result of his life.
- Saylor University - PHIL304: Existentialism - You've heard the phrase thrown around a lot, but what exactly is existentialism, and what does it mean to have an "existential crisis?" This course examines one of the most often-referenced but frequently-misunderstood topics in philosophy from every angle. By the end of the course, you'll understand its origins, logical reasoning, and how the philosophy has evolved over time.
- Macquarrie University - Becoming Human: Anthropology (BeHuman) - Professor Greg Downey - This course in anthropology will take you on a whirlwind journey from pre-history through to the modern day, and describe how some of the basic characteristics we associate with our humanity came to be. There's discussion of Darwin and human evolution, but there's also a great focus on the impact that our growing brains had on our societal development, and the role that sexual selection played even up to modern times (and the role that all of those factors still play in our societies).
- The University of Melbourne - Animal Behaviour - Professors Raoul Mulder and Mark Elgar - If you've ever wondered why animals do what they do, where the line is between instinctual behaviour and force of will, and why animal behaviour is predictable at some times and completely wild at others, this course will illuminate the topic for you. You'll come to understand how animals compete over resources, how evolutionary biology influences the actions of individuals and groups, mate selection and migration and movement patternsmore. You'll study the basics, like biology and evolution, but you'll also get into social constructs and passed-down traits, like familial behaviour, parental care and social conflicts.
- Griffith University - Understanding the Origins of Crime - Professor Dr. Aaron Sell - When we ask "why" someone committed a crime, we usually look to their direct motive -- whether they were angry, needed money, wanted revenge or made a mistake. In this course, you'll take a broader look at the origins of crime and criminal behaviour -- one that starts with the concepts of human evolution and natural selection. Dr Sell examines why crime is a social construct and how it's been sociologically and biologically coded into who we are as a species.
- TED - Cyber-Influence and Power (iTunes U) - The internet presents new challenges and opportunities for people, organisations, and states to exercise their will, enforce their foreign policies, inspire revolutions or horrifying crimes, and act against other competing organisations. This series of TED talks discusses the topic from the perspective of everyone involved, from the activist looking to keep information free, the protester who wants their voice heard by power-brokers, state agencies and organisations that can use communication technology to flout international laws and legal sanctions.
- The Open University - Childhood and The Law (iTunes U) - While many people focus exclusively on how the law impacts adults and the crimes they commit, legal issues around children are much murkier and often controversial. This course examines topics such as adoption, the legal boundaries for adoptive parents or children who want to seek their birth parents, social work and child welfare issues, children and violence, and more. The course studies the topic from the perspective of international law, and examines how laws and legal penalties shift from culture to culture and nation to nation.
Cross-Disciplinary Courses and Seminars
- The University of Tokyo - Conditions of War and Peace - Professor Kiichi Fujiwara - Why do we wage war in the name of peace and security? What have we learned about the history of war and what does that tell us about the future of armed combat? This course will ask some seemingly simple questions and get into their very complicated answers, like "When is war necessary?" and "What does peace look like?" The class will challenge your perceptions of what exactly a peaceable nation looks like, under what conditions an armed country or populace should fight -- either to defend themselves or in response to direct or implied aggression.
- Calarts - Live!: A History of Art for Artists, Animators and Gamers Professor Jeannene Przyblyski, Ph.D. - This course approaches the history of art and design from the perspective of artists, covering topics including video games, movies, computer animation, cartoons, and how all of the artists who make those works get it all done. You'll approach both the history of and the application of art from the context of contemporary art and artists, and consider the "conversation" that makers have with their mediums. The course seeks to help you understand how an artist manages to tell a story with something like a sculpture or a computer animation, and what a modern game designer can learn from classical painting.
- Center for Creative Leadership - Leadership for Real - This course series focuses on ways you can develop your leadership skills. If that sounds trite, think again -- you'll get video lectures, interactive discussions with other classmates, and a laser focus on real-world applications of the skills you'll learn. Whether you're already a manager looking to be a better boss to your staff or you're someone just interested in developing those "leadership skills" that so many employers want, this course can help you build them.
- Penn State - Creativity, Innovation And Change - Dr. Jack V. Matson, Dr. Darrell Velegol and Dr. Kathryn W. Jablokow - In this course, you'll learn to develop your own powers of creative thinking and apply them to even the most rigorous, routine responsibilities and duties you have in your day-to-day life. The goal of the course is to give you a way to develop your creative potential to make positive changes in your life, in your community, and in your work.
- Taylor's University - Success - Achieve Success with Emotional Intelligence - Professors Mushtak Al-Atabi and Jennifer DeBoer - We've often taught that success comes from working hard, getting good grades, making money, or doing a good job at work, but there's more to the story. This course helps you first define success in terms that are actually meaningful, then rewire your brain to understand what happiness and success really mean to you and how to attain them (or rather, that you may already have them). You'll learn what "emotional intelligence" really means, and how it plays a significant role in your interpersonal relationships, both at work or in your personal life, and how that understanding can help improve those relationships in all aspects of your life.
- Udacity - The Design of Everyday Things - Professors Don Norman, Kristian Simsarian, and Chelsey Glasson - Design is everywhere. It's all around us, from the apps on your smartphone to the building you live in and the clothes you wear. This course aims to help you understand the role that design plays in our everyday lives, how designers do their work, and how even you do design when you organise a room or set up a home or apartment. By the end of the class, you'll be able to offer real critiques, you'll have a better understanding of what exactly "design" entails and how it works, you'll understand your own personal eye for design, and you'll be able to appreciate design in a way you may not have before.
- University of Colorado Boulder - Comic Books and Graphic Novels - Professor William Kuskin - Comic books and graphic novels are fun and entertaining to read, but there's more to them than the pretty pictures. They're some of the most engaging, informative and innovative art forms we have, and this course will help you appreciate them in a brand new light. You'll examine (but move beyond) the traditional comics and names you may be familiar with and study comic books as an art form with their own canon, literary traditions, and long (and sometimes turbulent) history in the United States. You'll see how the medium grew from simple entertainment to entertainment aimed at children, then adults, then all audiences, and how society has reacted to the evolution of stories, imagery, and narrative through the years.
- University of Illinois at Urbana-Champaign - Introduction to Sustainability - Professor Jonathan Tomkin - "Sustainability" is a buzzword used in environmental and ethical debates, but what does it really mean, and what would it take for us to live a truly sustainable lifestyle? This course examines those topics, and how human societies can adapt to embrace global changes, growing populations, and dwindling resources. You'll study the Tragedy of the Commons, and you'll dive into the mathematics and science involved in population growth and change, migration, energy use and its environmental effects, and contemporary issues in energy and fossil fuels, transportation, agriculture and water usage.
