Ethanol Biofuel
This video segment adapted from NOVA examines ethanol, a cleaner-burning fuel alternative to gasoline, and the efforts to produce it more efficiently. Today, most ethanol in the United States is made from corn kernels. But converting corn into ethanol requires lots of energy as well as corn, which might otherwise be used to feed people and livestock. The video features research efforts to use less valuable plant matter, called cellulosic biomass, and microorganisms that may be able to accomplish
Engineering Biofuels
This video segment adapted from KQED's QUEST profiles the work of Jay Keasling, a synthetic biologist experimenting with ways to produce a cleaner-burning fuel from biological matter, using genetically modified microorganisms. Keasling's approach involves engineering microbes to eat simple sugars found in plant matter and then excrete fuel. The video explains the two techniques that may enable Keasling to accomplish this: metabolic engineering and directed evolution. It also suggests that creati
How to Use WatchKnow

Tips On Categorizing Videos on WatchKnow.org
This WatchKnow video tutorial (a screencast) explains how to fix common problems with categorizing videos and editing the Directory. Topics include: (1) unsorted videos; (2) using too borad of a category; (3) the category you need doesn't exist yet; (4) too many videos in a category; (5) how to deal with multi-part videos; (6) duplicate categories; (7) specialized category not filed "deeply" enough; (8) category names not in Title Case.

Marathon Migrators
There are many strategies animals use for staying close to their food sources, as this video segment from NOVA: "The Mystery of Animal Pathfinders" explains. One of the most remarkable of these strategies, however, is demonstrated by the red knot, a species of shorebird that flies 20,000 miles annually in its never-ending search for food, especially the eggs of spawning horseshoe crabs. Closed captioning included. Run time 6:00.

Calisphere Themed Collection - 1780-1880: California in Transition: Californio Society, 1830s-1880s
This is a primary source photo collection on Californios, elite families that received large land grants from Spain and Mexico, flourished during the 1830s to 1880s. The hand-drawn diseño maps underscore their vital connection to land ownership. The more formal surveyed maps that followed US acquisition of California show changing values regarding land ownership. As Californios lost land and power in the late 19th century, they tried to adapt to these changes by using social networks to maintai
The PDZ Domain as a Complex Adaptive System
Specific protein associations define the wiring of protein interaction networks and thus control the organization and functioning of the cell as a whole. Peptide recognition by PDZ and other protein interaction domains represents one of the best-studied classes of specific protein associations. However, a mechanistic understanding of the relationship between selectivity and promiscuity commonly observed in the interactions mediated by peptide recognition modules as well as its functional meaning

"Chemistry of Sports, Spring 2009"
" This seminar will focus on three sports: swimming, cycling and running. There will be two components to the seminar: classroom sessions and a "laboratory" in the form of a structured training program. The classroom component will introduce the students to the chemistry of their own biological system. With swimming, running and cycling as sample sports, students are encouraged to apply their knowledge to complete a triathlon shortly after the term."
