James Barber Brookhaven National Laboratory Photosystem II by James Barber on: Brookhaven National Laboratory James Barber, Ernst Chain Professor of Biochemistry at Imperial College, London, gives a BSA Distinguished Lecture titled, The Structure and Function of Photosystem II: The Water-Splitting Enzyme of Photosynthesis. April 18, 2005.
Judah Folkman Harvard Medical School The discovery of angiogenesis inhibitors: A new class of drugs on: Woods Hole Oceanographic Institution The process of angiogenesis--the growth of new capillary blood vessels--is now recognized as a powerful control point in cancer. The hypothesis that tumors are angiogenesis-dependent has been confirmed by genetic methods and has stimulated angiogenesis research in many laboratories. As a result, angiogenesis inhibitors have emerged as a new class of drugs.
The Missing Secrets of Nikola Tesla on: Google Video Nikola Tesla was a world-renowned Serb-American inventor, physicist, mechanical engineer and electrical engineer. Tesla is regarded as one of the most important inventors in history, but also made bizarre claims late in his career.
Air Pollution May Impact Heart Health on: Discovery Channel A University of Washington study finds long-term exposure to air pollution is linked to heart disease and death.
Border Wall Could Block Wildlife on: Discovery Channel The presence of Jaguars along the U.S.- Mexico border means that a new wall may also create an impasse for them and other wildlife. Jorge Ribas investigates.
Julia A. Kornfield California Institute of Technology Unsolved Problems In Biomedical Materials Engineering on: Caltech Dr. Julia A. Kornfield, Associate Professor of Chemical Engineering at Caltech, and Dr. David A. Tirrell, Ross McCollum-William H. Corcoran Professor of Chemistry and Chemical Engineering at Caltech, presented this lecture as part of the 0.1 Seminar series. They discuss some of the complications and challenges that arise in the clinical use of medical devices that are surgically implanted each year, and present some current approaches to the amelioration of the resulting problems.
Shane Ross California Institute of Technology Shane Ross: The Interplanetary Transport Network on: Caltech Shane Ross, graduate student in control and dynamical systems at Caltech, discussed how to identify and traverse a vast array of low-energy passageways that winds around the sun, planets, and moons that is created by the competing gravitational pull between celestial bodies. Space travel along these corridors would slash the amount of fuel needed to explore and develop our solar system.
Vinod Khosla Kleiner, Perkins Biofuels: Think Outside The Barrel on: Google TechTalks Vinod Khosla, visited Google to deliver a tech talk about the emergence of ethanol as a viable, market ready, and competitive source of renewable energy.
Melinda Kellogg California Institute of Technology Stalking the Exciton Condensate on: Caltech Melinda Kellogg, a graduate student in physics at Caltech, discussed the creation of Bose-Einstein condensation (BEC) of stable excitons in neighboring layers of two-dimensional electron gases embedded in highly engineered semiconductor crystals. Observing the superfluid-like flow of these excitons was evidence that the long-sought exciton condensation had finally been achieved.
Donald McNeil New York Times A Simple Solution for Clean Water on: New York Times Donald G. McNeil Jr. demonstrates how a new personal water filter, worn around the neck, could help ensure people around the world have clean water to drink.
