This course will discuss HIV/AIDS in the US and around the world including its history, science, and culture as well as developments in behavioral and biomedical prevention, experimental AIDS vaccines, and clinical care issues. The course will also include a discussion of the populations that are particularly vulnerable to HIV/AIDS and a look at future challenges facing people infected and affected by the AIDS pandemic.
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
This course will survey fundamental principles of cognitive and behavioral neurology. The emphasis of the course will be on the neural mechanisms underlying aspects of cognition and on diseases that affect intellect and behavior. No prior background in neurology, medicine, or neuroscience is required.
A thorough understanding of the systems of the body and the ways in which they fit together is imperative for study in many fields of biological inquiry, including medicine, physiology, developmental studies, and biological anthropology. This course will provide you with an overview of the body from a systemic perspective. Each unit will focus on one system, or network of organs that work together to perform a particular function. At the end of this course, we will review the body from an integrative perspective, creating a more realistic vision of the ways in which the systems overlap. We will also discuss current body imaging techniques and learn how to correctly interpret the images in order to put our newly-gained anatomical knowledge to practical use. This is a terminology-heavy course. We will identify tissues and organ systems according to their functional and regional contexts, but information concerning the processes by which the tissues and organ systems actually function will be covered…
Genetics is the branch of biology that studies how traits are passed on from one generation to the next and why there are similarities and differences between related individuals. Prior to the discovery of genes, scientists knew that parents passed something down to their offspring, but they did not know how or what. Gregor Mendel’s famous experiments with peas indicated that certain features, such as pea texture and flower color, are encoded by two sets of traits and that the parental traits can be separated. Decades later, scientists discovered that parents passed down DNA, which was present in chromosomes. Since the discovery of DNA, we have come to appreciate the importance of chromosomes. Genomics is a relatively new field with the bold aim of understanding the function of every single gene in a genome, including the human genome. This field took off with the completion of the first sequenced genome, and after the completion of the Human Genome Project, it has attracted increasing research. Mendelian…
