7.3 Formation of prostaglandin
What causes pain and how do we stop it? This unit looks at how the human body responds to the release of certain chemicals and as a result feels pain. Pain can be reduced by inhibiting the formation of such chemicals and you will learn how the molecular structure of aspirin has been formulated to help in this process.

Nucleic acids and chromatin
This unit helps you understand the properties of nucleotides and how they contribute to secondary and tertiary structures of nucleic acids at the molecular level. You will learn about the different composition and roles of nucleic acids in the cell, their interactions with each other and the use of ribozymes, aptamers, antisense and hybridization as tools in molecular research. The unit covers the function of DNA packaging within the cell, the interactions between the DNA double helix and the nu

Veggie Tales-The Star of Christmas part 1
The VeggieTales gang is back for their second Christmas episode. Though the setting is Victorian England, old Ebenezer Scrooge is nowhere in sight, refreshingly. Cavis Appythart and Millward Phelps (Bob and Larry) are just finishing up their first holiday musical in an effort to "teach London to love." However, their hearts aren't in the right place, and the play has more electrical lights than well-meaning words. When they learn that a local church plans to bring out a priceless artifact for th

7.343 Photosynthesis: Life from Light (MIT)
In this course, you will journey through the web of physical, chemical, and biological reactions that collectively constitute photosynthesis. We will begin with light harvesting and follow photons to the sites of primary photochemistry: the photoreaction centers. A molecular-scale view will show in atomic detail how these protein complexes capture and energize electrons. Then we will follow the multiple pathways electrons take as they carry out their work. Consequent reactions, such as the synth

Plate Tectonics: An Introduction
In the early 1900s, most geologists thought that Earth's appearance, including the arrangement of the continents, had changed little since its formation. This video segment adapted from Discovering Women describes the impact the theory of plate tectonics has had on our understanding of Earth's geological history, as we have become aware of our planet's ever-changing nature. Closed captioning included.  Run time 02:21.

Renal Pathophysiology
The importance of the kidneys is most clearly demonstrated in the presence of pathophysiologic states. The kidneys play a central role in the maintenance of the internal milieu by balancing fluid, electrolytes, and hydrogen ions to provide optimal conditions for molecular, cellular, and body system function. They also serve as the major excretory organ for metabolic byproducts, drugs, and other organic substances. Finally, the kidneys are an important endocrine organ, producing vasoactive factor

Genetic Origins
The goal of the Genetic Origins Program is to allow students to use their own DNA variations (polymorphisms) as a means to explore our shared genetic heritage and its implications for human health and society. Genetic Origins focuses on two types of DNA variations: an Alu insertion polymorphism on chromosome 16 (PV92) and single nucleotide polymorphisms (SNPs) in the control region of the mitochondrial (mt) chromosome. With two alleles and three genotypes, PV92 is a simple genetic system that il

Extended architecture of knowledge management system with Web 2.0 technologies
Knowledge management systems (KMS) become increasingly important in periods of crises and economic slowdown, as many organizations are forced to lay off people, to reduce research and ICT budgets, to restructure departments and to optimize their costs. Subsequently, organizational knowledge assets, and mainly the existing tacit knowledge are threatened. This raises the importance of technologies that could assist organizational efforts to capture the existing knowledge and to mobilize it in orde
