This course covers introductory microbiology from a systems perspective, considering microbial diversity, population dynamics, and genomics. Emphasis is placed on the delicate balance between microbes and humans, and the changes that result in the emergence of infectious diseases and antimicrobial resistance. The case study approach covers such topics as vaccines, toxins, biodefense, and infections including Legionnaire’s disease, tuberculosis, Helicobacter pylori, and plague.

Chemistry and biology are traditionally taught as separate subjects at the high school level, where students memorize fundamental scientific principles that are universally accepted. However, at the university level and in industry, we learn that science is not as simple as we once thought. We are constantly confronted by questions about the unknown and required to use creative, integrated approaches to solve these problems. By bringing together knowledge from multidisciplinary fields, we are empowered with the ability to generate new ideas. The goal of this course is to develop skills for generating new ideas at the interface between chemistry and biology by analyzing pioneering studies.

This course consists of an international analysis of the impact of epidemic diseases on western society and culture from the bubonic plague to HIV/AIDS and the recent experience of SARS and swine flu. Leading themes include: infectious disease and its impact on society; the development of public health measures; the role of medical ethics; the genre of plague literature; the social reactions of mass hysteria and violence; the rise of the germ theory of disease; the development of tropical medicine; a comparison of the social, cultural, and historical impact of major infectious diseases; and the issue of emerging and re-emerging diseases.

Motion, speed and time are three fundamental concepts in basic physics and they are important building blocks for understanding more advanced topics. This free online course introduces you to how distance, speed, time and mass are combined to give displacement, velocity, force and acceleration. Newton’s 3 Laws of Motion, which are the bedrock of much of our understanding of physics today, are also introduced and explained in a clear and concise manner. Along with explanations of the formulae used, a number of examples are worked through, giving a full understanding of the subject. References are also made as to how these formulae are used in real-world situations. By studying this course you will gain a clearer knowledge and understanding of important topics in basic physics. This course will be of great interest to students who are studying physics, chemistry, engineering, mathematics and some medical sciences, and to students who wish to pursue a career in any of the sciences or engineering fields, and to the individual who wants to understand how the world around us works.<br />

Animal welfare has been described as a complex, multi-faceted public policy issue which includes important scientific, ethical, and other dimensions. Improving our understanding of animal welfare, involves the fascinating study of animal behavior as well as the challenge of accessing the emotions of animals. This is the second time we have run this course, and we have revised some of the content and assessments in line with the great feedback we gained from our first run through. We have also added some subtitles to the videos for the Spanish and Mandarin speakers who wish to participate. Talk about this course using the hashtag #EdAniWelf

During each week of this course, chefs reveal the secrets behind some of their most famous culinary creations — often right in their own restaurants. Inspired by such cooking mastery, the Harvard team will then explain the science behind the recipe.

Topics will include:

• How molecules influence flavor
• The role of heat in cooking
• Diffusion, revealed by the phenomenon of spherification, the culinary technique pioneered by Ferran Adrià.

You will also have the opportunity to become an experimental scientist in your very own laboratory — your kitchen. By following along with the engaging recipe of the week, taking precise measurements, and making skillful observations, you will learn to think like both a cook and a scientist. The lab is certainly one of the most unique components of this course — after all, in what other science course can you eat your experiments?

This course covers chemicals in our environment and in our bodies and how they impact our health. It addresses policies and practices related to chemicals, particularly related to how they get into our bodies (exposures), what they do when they get there (toxicology), how we measure them (biomonitoring) and their impact on our health.

Do you want to develop the skills and knowledge needed to help preserve tropical coastal ecosystems? These habitats provide goods and services for hundreds of millions of people but human activities have led to their global decline. TROPIC101x will introduce you to the incredible plants and animals that create these unique ecosystems. You will go on to explore the challenges these ecosystems are facing such as overfishing, coastal pollution, ocean warming and acidification, then learn about some techniques being used to tackle these problems. Lectures will be delivered by leading experts. Many of them were filmed on-site in the Great Barrier Reef, at The University of Queensland’s research station on Heron Island. The course concludes with an innovative virtual ecology project, where you will have the option to take part in a citizen science project. Join us on an exciting journey, as you develop new knowledge and skills, during this beautiful and engaging course!
