2,4-Dichlorophenoxyacetic Acid Pathway Map
Read the Fine Print
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
Read the Fine Print
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.

Abacus: The Art of Calculating with Beads
Read the Fine Print
Rating

The abacus has been around for several thousand years, and it is an efficient and interesting counting machine. The standard abacus can be used to perform addition, subtraction, division, and multiplication, along with its use in extracting square roots and cubic roots. This site was created by Luis Fernandes, and it explores the wide world of the abacus through illustrations, thoughtful essays, and other items. On the site's homepage visitors can read a detailed introduction to the abacus, look over an interactive abacus tutorial, and learn about the history of the device. In the "Articles, Excerpts and Analysis" area visitors can read about an early encounter between the abacus and an electric calculator in 1946 and a hilarious encounter between famed physicist Richard Feynman and the abacus. The site is rounded out by the "All Things Abacus" area, which includes resources for teachers and photos of Fernandes' impressive abacus collection.

About NCBI
Read the Fine Print
Rating

The National Center for Biotechnology Information (NCBI) has had a Web site for some time now, but the site has recently become more user-friendly with this new About section. About NCBI explains NCBI's role in facilitating research and education specific to the "fundamental molecular and genetic processes that control health and disease." An introduction to NCBI databases and maps helps researchers select tools that may help them. A particularly helpful feature is entitled A Science Primer, which provides an easy-to-read introduction to many science topics relevant to NCBI's resources like bioinformatics, genome mapping, molecular modeling, and molecular genetics. This is an excellent site that should serve to orient both new users and those who have visited the NCBI site before.

Aerial Photographs of Colorado
Read the Fine Print
Rating

From 1938 to 1947, the United States Forest Service took thousands of aerial photographs of the state of Colorado. The hope was that these images would be used by agronomists, land use planners, farmers, and other groups with a vested interest in these lands. Today, 1,700 of these images are part of the University of Colorado's Digital Collections. Visitors can search for available images by using a clickable map here, read a set of interpretation tips, and also download the maps for research and other personal uses. Visitors who choose to use the LunaInsight image viewer (also made available here) will have the ability to search images by all data fields, along with being able to zoom in to high resolution images of each photograph. Overall, this is a tremendous resource, and one that will delight and inform geographers, historians, planners, and others with an interest in Colorado.
