Juan Enriquez wants to Grow Energy
Juan Enriquez challenges our definition of bioenergy. Oil, coal, gas and other hydrocarbons are not chemical but biological products, based on plant matter -- and thus, growable. Our whole approach to fuel, he argues, needs to change. Juan Enriquez thinks and writes about the profound changes that genomics and other life sciences will cause in business, technology, politics and society. This video could also be used with a lesson in agriculture. Run time 18:08.
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
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 Edit WatchKnow
Here's a carefully edited screencast explaining how to edit Watchknow. This excellent screencast describes: (1) installing the bookmarklet; (2) importing videos with the bookmarklet; (3) editing the directory; and (4) recategorizing videos. This screencast was developed by none other than the original designer of WatchKnow, Dr. Larry Sanger. (08:27)
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.

SAMPEX - A Synoptic View of Earths Electron Radiation Belts: South Pole Energetic Fluxes from HILT
The Solar Anomalous and Magnetospheric Particle Explorer, SAMPEX, measures fluxes of energetic particles from the sun, the Earths magnetosphere, and cosmic ray sources over a broad range of energies. The four instruments aboard SAMPEX are the Low-Energy Ion Analyzer (LEICA), The Heavy Ion Large Telescope (HILT), The Mass Spectrometer Telescope (MAST), and the Proton-Electron Telescope (PET).
A Rotating True Color View of the Martian South Pole
This is one of a series of visualizations showing false-colored renderings of the Martian topography measured by MOLA in the vicinity of the Mars Polar Lander landing site. Blue tones represent elevations of less than 2 kilometers, while reddish tones are greater than about 2.8 kilometers, relative to the mean equatorial height of Mars. The elevation of the landing site is about 2.4 km, midway into the polar layered terrain. The 400 meters (1-4 mile) resolution of the MOLA data gives a smoothed
Duke Patient Story: Eric Gabriel
Eric Gabriel came to Duke when his doctors could no longer help him with his knee. Watch his emotional journey -- and keep watching until the end to see the latest chapter in his story.
Salman Khan: Let's Use Video to Reinvent Education
Salman Khan talks about how and why he created the remarkable Khan Academy, a carefully structured series of educational videos offering complete curricula in math and, now, other subjects. He shows the power of interactive exercises, and calls for teachers to consider flipping the traditional classroom script -- give students video lectures to watch at home, and do "homework" in the classroom with the teacher available to help.

The Religious Origins of Modern Science
Prof. Peter Harrison : Course
Aftershock: Europe And The Post-Crisis World [Audio]
Speaker(s): Philippe Legrain | The financial crisis brought the world to the brink of economic breakdown. As bubble turned to bust, Depression loomed. Now bankers' bonuses are back, house prices are rising again and politicians promise recovery while unemployment remains high, debts mount, frictions with China grow and the planet overheats. Is this really sustainable - or do we need to change course?
The Polish Question at the End of the First World War [Audio]
Speaker(s): Professor Anita J Prazmowska | When the First World War broke out many assumed that it would inevitably lead to the re-emergence of a Polish state. As the war drew to an end the battle for Poland commenced on several fronts, both diplomatic and military. In the end, an independent Polish state would bear the mark of the way Poland re-emerged, placing the importance of nationalism above the need to build a modern democratic state. Anita J Prazmowska is professor of international histo
Unilaterally Appointed Arbitrators - A Good Idea? [Audio]
Speaker(s): Professor Jan Paulsson, Alexis Mourre | Jan Paulsson's recent paper on "Moral Hazard in International Arbitration" questioning the usefulness of having parties themselves appoint "their" arbitrators has stirred much controversy and will be challenged at this event by Alexis Mourre. Prof. Paulsson is Centennial Professor of Law at LSE, co-head of the international arbitration practice of Freshfields LLP and one of the world's leading arbitrators. Alexis Mourre is partner at Castaldi M
2.5 Corrosion processes: galvanic series
The I-35W bridge collapse in Minneapolis in August 2007, resulting in at least 13 deaths, illustrates the importance of structural integrity. This unit looks at the investigation that followed the collapse of the Silver Bridge over the Ohio River in 1967 which demonstrates how the study of safe design and the assessment of components and structures under load is of increasing importance in engineering design.
"Media and Methods: Seeing and Expression, Spring 2009"
" This class examines frameworks for making and sharing visual artifacts using a trans-cultural, trans-historical, constructionist approach. It explores the relationship between perceived reality and the narrative imagination, how an author's choice of medium and method of construction constrains the work, how desire is integrated into the structure of a work, and how the cultural/economic opportunity for exhibition/distribution affects the realization of a work. Students submit three papers and
