An introduction to the basics of marine science and conservation, brought to you with the help of sea turtles, marine mammals, seabirds and many more of the most compelling creatures in the ocean.
This course is about sea turtles, whales, dolphins, seals, penguins, sharks, giant squid and other large ocean creatures - collectively known as marine megafauna - and what they can tell us about how the ocean works and why it is so important for all life on earth.
This course will help you learn about life in the ocean, how ocean ecosystems function, how scientists study the ocean, and the challenges we face in sustaining healthy oceans for the future. These topics will be explored using case studies that focus on charismatic marine megafauna species – the most compelling creatures in the ocean that capture our attention and inspire us to learn more.
The course starts with an examination of the physical dimensions of the world’s ocean and how we describe ocean zones based on the ecosystems found within them. Once these basics are covered, we will work through the evolution of life in the oceans and explore how marine animals have adapted to the challenges of a cold, dark and deep ocean. Throughout the class we will highlight how scientists study the oceans and the animals that live in them, providing glimpses of new technologies that boost our understanding of marine ecology. The course will also cover some of the challenges the oceans face due to human activities - exploring issues such as bycatch and climate change - and how they are affecting ocean species and systems.
Throughout the course we will connect with real marine science through the use of open access scientific articles published in the journal PLOS ONE. This means you will have to learn how to read scientific papers and extract the important bits of information from them. The articles you’ll be reading are all part of a new PLOS Collection focused on using open access research to teach marine science and conservation. You will also get to look at real datasets produced by scientists studying marine creatures and visualize them in freely available programs such as Google Earth.
Imagine if there were an organ in your body that weighed as much as your brain, that affected your health, your weight, and even your behavior. Wouldn’t you want to know more about it? There is such an organ — the collection of microbes in and on your body, your human microbiome.
For centuries we have collectively marveled at plant diversity and form—from Charles Darwin’s early fascination with stems and flowers to Seymour Krelborn’s distorted doting in Little Shop of Horrors. This course intends to present an intriguing and scientifically valid look at how plants themselves experience the world—from the colors they see to the sensations they feel.
In this course you will learn how evolution works. You will develop an understanding of evolutionary processes and their formative power. You will see how evolution has shaped biodiversity, and continuously influences our daily life. Evolution impacts human endeavors as varied as medicine, agriculture, psychology, economy, and culture. It is the major unifying principle for biology and a fundamental natural law.
Introduction to Genetics and Evolution is a college-level class being offered simultaneously to new students at Duke University. The course gives interested people a very basic overview of some principles behind these very fundamental areas of biology. We often hear about new "genome sequences," commercial kits that can tell you about your ancestry (including pre-human) from your DNA or disease predispositions, debates about the truth of evolution, why animals behave the way they do, and how people found "genetic evidence for natural selection."
Comment cultiver des cellules humaines ? Comment les reprogrammer en cellules souches ? A la suite des travaux du prix Nobel Shinya Yamanaka, découvrez les principales étapes de culture et de reprogrammation des cellules humaines en cellules souches, et abordons ensemble les éléments fondamentaux de la biologie cellulaire.
These are very unique times for brain research. The aperitif for the course will thus highlight the present “brain-excitements” worldwide. You will then become intimately acquainted with the operational principles of neuronal “life-ware” (synapses, neurons and the networks that they form) and consequently, on how neurons behave as computational microchips and how they plastically and constantly change - a process that underlies learning and memory.
This course begins a series of classes illustrating the power of computing in modern biology. Please join us on the frontier of bioinformatics to look for hidden messages in DNA without ever needing to put on a lab coat.
Large-scale biology projects such as the sequencing of the human genome and gene expression surveys using RNA-seq, microarrays and other technologies have created a wealth of data for biologists. However, the challenge facing scientists is analyzing and even accessing these data to extract useful information pertaining to the system being studied. This course focuses on employing existing bioinformatic resources – mainly web-based programs and databases – to access the wealth of data to answer questions relevant to the average biologist, and is highly hands-on.
This course will introduce the student to contemporary Systems Biology focused on mammalian cells, their constituents and their functions. Biology is moving from molecular to modular. As our knowledge of our genome and gene expression deepens and we develop lists of molecules (proteins, lipids, ions) involved in cellular processes, we need to understand how these molecules interact with each other to form modules that act as discrete functional systems. These systems underlie core subcellular processes such as signal transduction, transcription, motility and electrical excitability. In turn these processes come together to exhibit cellular behaviors such as secretion, proliferation and action potentials.
Dog Emotion and Cognition will introduce you to the exciting new study of dog psychology, what the latest discoveries tell us about how dogs think and feel about us, and how we can use this new knowledge to further strengthen our relationship with our best friends.
