Timur Shaftan Brookhaven National Laboratory The NLS-II Project; 418th Brookhaven Lecture on: Brookhaven National Laboratory The NSLS-II project will establish a third-generation light source at Brookhaven Lab, increasing beam-line brightness by 10,000. Achieving and maintaining this will involve tightly focusing the electron beam, providing the most efficient insertion devices, and achieving and maintaining a high electron current. In this talk, the various sub-systems of NSLS-II will be reviewed, and the requirements and key elements of their design will be discussed. In addition, the a small prototype of a light source of a different kind that was developed by the NSLS will also be discussed.
Samuel Bogoch Replikins Ltd. Replikin genome sequences and survival rates in shrimp and human pandemics on: Replikins Ltd. Dr. Bogoch spoke at the World Aquaculture Conference in San Antonio, giving some background on his company's Replikins technology and announcing test results in conjunction with the University of Arizona. These results correlate virulence of four Taura virus strains in shrimp with the concentration of Replikin subsequences in the virus genomes. This is the first virus protein structure to have been shown to be quantitatively relate not only to the occurrence of epidemics, but now specifically to mortality rate of the host.
Hans Reiser Namesys The Reiser4 Filesystem on: Google TechTalks The ReiserFS project aims to add support for semi-structured data querying to the filesystem namespace. Reiser4 is the storage layer for this. It stores all files in a dancing (not balanced)tree, and is currently the overall fastest filesystem for traditional filesystem usage patterns.
Stewart Brand Long Now Foundation City Planet - Stewart Brand speaks at Google on: Google Video Whole Earth Catalog Founder, and GBN and Well cofounder Stewart Brand has long been fascinated by cities—how and why they are changing and the long-term implications for civilization. Join Stewart as he explores the nature of the emerging 'City Planet,' a world of megacities largely populated by the young; vibrant communities of squatters that are redefining environments, economies, and social norms; and massive urbanization that could represent a huge opportunity for environmentalists, though most haven't realized it yet.
Craig Venter Geneticist A voyage of DNA, genes and the sea on: TedTalks Genomics pioneer Craig Venter takes a break from his epic round-the-world expedition to talk about the millions of genes his team has discovered so far, in their quest to map the ocean's hidden biodiversity. (Quite a task, when you consider that there are tens of millions of microbes in a single drop of sea water.) He updates the TED audience on his discoveries, from the 2,000 photoreceptor genes found in the Sargasso Sea to the thrill of being under house arrest in French waters. After touching on the potential of environmental genomics to monitor the safety of air, water and offshore drilling, Venter ends with his vision for engineered species that can replace the petrochemical industry by creating clean energy.
Richard Schrock Massachusetts Institute of Technology Multiple Metal-Carbon Bonds for Catalytic Metathesis Reactions on: Nobelprize.org Richard R. Schrock held his Nobel Lecture December 8, 2005, at Aula Magna, Stockholm University. He was presented by Professor HŚkan Wennerstršm, Chairman of the Nobel Committee for Chemistry
Amy Wagers Harvard Medical School IDEAS Boston Youth Summit: Dr. Amy Wagers on: WGBH Forum Dr. Amy Wagers was drawn to science early in life and began her scientific career in high school studying animal behavior in a colony of ringtail lemurs at the Phoenix Zoo.
35th Anniversary of the Intel(r) 4004 Microprocessor on: The Computer History Museum and the Intel Museum invite you to mark the 35th anniversary of one of the most important products in technology history. Introduced in November 1971, the Intel(r) 4004 microprocessor was an early and significant commercial product to embody computer architecture within a silicon device. And it started an electronics revolution that changed our world.
Linda Buck Fred Hutchinson Cancer Research Center Unraveling the Sense of Smell on: Nobelprize.org Linda B. Buck held her Nobel Lecture December 8, 2004, at Sal Adam, Berzeliuslaboratoriet, Karolinska Institutet.
Connie Davis MacColl Institute for Healthcare Innovation Part 7: Making Change Happen at the Practice Level on: U. of Washington TV Connie Davis identifies four strategies for change in their setting at the practice and population level that can be used when implementing the Chronic Care Model. This lecture was taped at the 2004 Epidemiology, Biostatistics and Clinical Research Methods Summer Session co-sponsored by the Seattle VA Epidemiologic Research and Information Center (ERIC) and the University of Washington.
David Kelly IDEO David Kelly: The future of design is human-centered on: TED Talks Low-key and thoughtful, IDEO founder David Kelley seems the antithesis of the 'design star' -- and indeed, he says that product design, within the past two decades, has become much less about the design and more about the user who'll be experiencing it. In this classic 2002 talk, he shares some video of products coming out of IDEO, including Prada's famous high-tech dressing rooms, 'Dilbert's ultimate cubicle,' and a gotta-have-it gadget called Spyfish. He finishes by discussing a project he's passionate about: ApproTEC -- now called KickStart -- offering designs that give Kenyans the means to end poverty.
Marcus J. Tindall Centre for Mathematical Biology Spatiotemporal Modelling of Intracellular Signalling in Bacterial Chemotaxis on: Whilst theoretical models have been used to understand aspects of bacterial chemotaxis systems for the past thirty or so years, little work has focused on the importance that spatial localisation of proteins within the cytoplasm of the cell has on the overall functionality of the intracellular network. In this talk we will examine spatio-temporal models of signal transduction developed to describe the phosphotransfer pathway within E. coli. This model framework will then be extended to examine the importance of protein localisation within R. sphaeroides, a species which contains considerably more phosphotransfer proteins than E. coli and the spatial localisation of which plays a particularly important role in activating certain elements of the phosphotransfer network. The difficulties encountered in obtaining robust parameter estimates for reaction rates within the R. sphaeroides will also be detailed. Joint work with S. L. Porter, P. K. Maini and J. P. Armitage.
Sidney Nagel University of Chicago Singularities and Topological Transitions: Breaking Away, Selective Withdrawal, Islets in the Stream. on: Fermilab Colloquium Lectures The exhilarating spray from waves crashing into the shore, the distressing sound of a faucet leaking in the night, and the indispensable role of bubbles dissolving gas into the oceans are but a few examples of the ubiquitous presence and profound importance of drop formation and splashing in our lives. During fission, a fluid forms a neck that becomes vanishingly thin at the point of breakup.
Richard Dawkins Oxford University The universe is queerer than we can suppose on: TedTalks Biologist Richard Dawkins makes a case for 'thinking the improbable' by looking at how our human frame of reference -- the things we can perceive with our five senses, and understand with our eight-pound brain -- limits our understanding of the universe. Think of it: We can't see atoms, we can't see infrared light, we can't hear ultrasonic frequencies, but we know without a doubt that they exist. What else is out there that we can't yet perceive -- what dimensions of space, what aspects of time, what forms of life? Dawkins calls the human-size frame of reference 'Middle World': between the microcosmos of atoms and the macrocosmos of the universe. Middle World thinking limits our ability to see the universe in terms of the improbable, whereas 'in the vastness of astronomical space and geological time, that which seems impossible in Middle World might turn out to be inevitable.'
The Good, the bad and the undrinkable: the science of beer on: sciencelive David is a master Brewer from Woodfords. He has a background in chemistry but turned to brewing after joining the home brewers club. He chats to charlotte about the brewing process, letting her taste some malt and rub some hops. He also talks about many of the rigorous scientific tests breweries have to carry out on their beer to check for contamination or wild yeast strains
