This seven week course will explore nutrition concepts that take center stage in mainstream media outlets and become conversation topics among consumers interested in food choice as it relates to optimal health and physical performance.

You will become intimately acquainted with the operational principles of neuronal “life-ware” (synapses, neurons and the networks that they form) as well as with recent ideas about how the dynamics of these networks generate the “neuronal code.” As an aperitif we will highlight present brain-excitements and for dessert we will discuss the future of brain research

This course will introduce you to some of the science behind food preparation, cooking methods, and generally, the enjoyment of food. The ultimate goal is to inspire you to apply scientific principles in your everyday cooking, including the principles of manipulating the human perception of food.

This college-level course gives students a thorough understanding of gene function, and enables them to apply this understanding to real-world issues, both personal and societal. This is Part 1 of a two-part course; Part 2 focuses on the study of of how genes and traits are inherited.

This course teaches scientists to become more effective writers, using practical examples and exercises. Topics include: principles of good writing, tricks for writing faster and with less anxiety, the format of a scientific manuscript, and issues in publication and peer review.

Evolution and natural selection are very important concepts that have revolutionised our understanding of biology. Natural selection is a process resulting in the evolution of organisms that are best adapted to their environment, usually occurring over thousands, and even millions of years. In this free online biology course you will be introduced to the concepts of evolution and natural selection, the causes of these fundamental biological processes and how the success of a species can depend on changes to just one allele on one gene in one chromosome. You will study the naturally occurring variation within species and how mutations and reproduction continues this process. You will also be introduced to DNA, the blueprint of life forms on earth, by looking both at its physical structure and how it copies itself, and turns into the proteins that make up all living organisms. This free online biology course will be of great interest to all learners who wish to pursue a career in the sciences and medicine, to learners who are already studying subjects such as biology, biodiversity and biochemistry, and the individual who simply wants to learn more about how and why there is such diversity among plants and animals today.<br />

This free online course in Chemistry looks at elements, electrochemistry and food chemistry among other topics. It is an ideal course to engage students and help them grapple with the subject matter in an interactive and self-paced manner. It is particularly suitable for any student of chemistry at second level, or anyone who wants to gain more knowledge and understanding of the world of chemistry.

This free online course offers an in-depth exploration of general, organic and analytic chemistry. It examines various topics such as chemical equilibrium, rates of reaction, chromatography and their applications in real-world industries. These tutorials are are an excellent complement to chemistry classes for students or for those working in the chemical industry who would like to refresh their knowledge of these topics.

Two fundamental aspects of chemistry are, firstly, the structure of the atom and the role of the subatomic particles neutrons, protons and electrons, and, secondly, the atomic structure of the known elements that make up everything and how their place in the Periodic table of the elements determines their chemical properties. This free online course will give learners a comprehensive knowledge and understanding of these two core building blocks within chemistry. The course starts by examining the structure of the atom and subatomic particles, and then discusses the elements, and breaks them down into their subatomic structure of protons, neutrons and electrons. You will learn how the structure of each element determines its place in the Periodic table and its chemical properties. This course will be of great interest to all students who wish to pursue a career in any of the sciences such as chemistry, physics, biology or geology, or the individual learner who simply wants to learn and understand what the world around us is made up of.<br />
