The 1882 Transit of Venus: Observations from Wellington, South Africa
Rating

The transit of Venus is a rare astronomical event that has been well documented throughout history. The most recent transit occurred in June of 2004, and the one before that took place more than 100 years earlier in 1882. This site from the South African Astronomical Observatory provides information and first-hand observations of the 1882 event from Wellington, South Africa. Just prior to the event, an observatory was erected at the Huguenot Seminary for girls, and some of the historical observations made from that site in 1882 are provided here for your perusal.

2,4-Dichlorophenoxyacetic Acid Pathway Map
Rating

The University of Minnesota Biocatalysis/Biodegradation Database (UM/BBD) contains "microbial biocatalytic reactions and biodegradation pathways primarily for xenobiotic, chemical compounds." A new microbial enzyme-catalyzed reactions has been posted for 2,4-Dichlorophenoxyacetic Acid. 2,4-dichlorophenoxyacetic acid (2,4-D) is used in cultivated agricultural areas, rangeland and pastures, forests, and homes or gardens, and is "a chlorinated phenoxy compound [that] functions as a systemic herbicide and is used to control many types of broadleaf weeds." The degradation pathway map includes organisms which can initiate the pathway. The pathway map provides detailed information on each hyperlinked step, including graphics, product/substrate reactions, and external links to further information.

2MASS Second Incremental Data Release Gallery
Rating

On July 14, NASA announced the public release of a huge collection of images (1.9 million) from the Two-Micron All Sky Survey (2MASS), the most thorough census of stars ever made. Using two automated, 51-inch telescopes, one in Arizona and the other in Chile, the three-year-old survey has so far taken images of half a million galaxies and 162 million stars. By its completion, the survey's catalogs will contain more than 300 million objects. A sampling of these images has been placed online at the 2MASS site at the Infrared Processing and Analysis Center (IPAC) at the California Institute of Technology. The twelve-page gallery contains some amazing images, including the center of the Milky Way, the Sombrero galaxy, the Crab Nebula, and the Dark Nebula, offered as large thumbnails which link to a full-sized image. Users can learn more about 2MASS at the survey's homepages at Caltech and the University of Massachusetts.

50 Years of Electron Biprism -50 Years of Exciting Electron Physics
Rating

In 1953, Gottfried Moellenstedt invented the electron biprism, more or less by accident, with the serendipity characteristic to him: Aiming at dark-field imaging in an electron microscope, he stretched a thin tungsten wire across the objective aperture to block off the zero beam. However, instead of a dark field image, because of inadvertent charging of the wire under the beam, he found two images of the ZnO-needles serving as an object. Instead of trying the dark field imaging over and over again, he asked what the effect would be if the obtained two images were superimposed. Is coherence given? Moellenstedt, educated by Walther Kossel in diffraction of electron waves, had a vision: Together with his PhD-student Heinrich Dueker, he developed the electron biprism, consisting of a 1 micron m thin wire deliberately chargeable by means of a voltage source, as a beam splitter for coherent superposition of the electron waves passing the filament on the right and on the left. In 1955 they published the first results showing biprism interference fringes [G. Moellenstedt and H. Dueker, Naturwiss. 42, 41 (1955)], which, since then, gave access to the understanding of electron waves and their use for analysis of object structures up to atomic dimensions.

This resource introduces students to the Dry Valleys of Antarctica, the largest area on the continent that is not covered by ice. Materials include a map and some brief facts about Antarctica and the valleys, such as size, location and physical properties (temperature, precipitation and others), and an online journal in which participants in the Dry Valleys Long-Term Ecological Research (LTER) project discuss what it is like to live and work there. The journal entries include descriptions of some of the organisms that inhabit the extreme environments of the valleys, physical features of the valleys, and the strange mummified bodies of animals such as penguins and seals that have been preserved in the cold, dry climate. There is also a glossary of acronyms used in the project and a set of links to other websites with additional information about the Dry Valleys.
