  1. IMAGES: To the Bone

    Digital Morphology from the University of Texas, Austin, serves as a virtual anatomy lab for students and allows researchers to analyze hard-to-find specimens. The site uses an x-ray computed tomography scanner to peek inside more than 500 animals, plants, and fossils. For instance, you can call up the skull of the world's largest hummingbird (Patagona gigas), which tips the scales at 24 grams. Three-dimensional movies let you spin and flip the skull to study it from different angles. You can also view it slice by slice to highlight internal details, or compare the hummingbird's feeding adaptations to those of another nectar-slurping bird. The site provides background on each species, details on the specimens, and other information.

  2. RESOURCES: Immunologists of NIH, Unite!

    Immunologists in the National Institutes of Health's (NIH's) intramural program are scattered among more than a dozen institutes. The new hub Immunology@NIH connects researchers in far-flung labs and helps outside scientists track down potential collaborators. The site holds a directory of some 150 NIH scientists who are probing the immune system. Visitors can also browse a listing of training opportunities or dig into a video archive that houses 4 years of immunology seminars by NIH staff members and other researchers.

  3. COMMUNITY SITE: Up on the Plateau

    Tibet has lured researchers studying everything from traditional forms of conflict resolution to the effects of high elevation on child survival. Whether you're an anthropologist or a physiologist, you'll find plenty of information about the lofty region at the Web site of the Center for Research on Tibet at Case Western Reserve University in Cleveland, Ohio. Visitors can download papers and online books—written by researchers at the center and outside scholars—on marriage customs, social systems, and other topics. The average elevation on the Tibetan plateau exceeds 4000 meters, and the site houses more than a dozen publications on residents' adaptations. Tibetans can crank up blood flow to the brain faster than lowlanders can, for instance, and their lungs pump out more nitric oxide, which dilates vessels and appears to speed the absorption of oxygen.

  4. HISTORY: Integrating Mathematics

    When officials at Johns Hopkins University in Baltimore, Maryland, announced their math graduate fellowship in 1876, they were thrilled to offer admission to “C. Ladd”—not realizing that the “C” stood for “Christine.” Thanks to the support of a powerful professor, Christine Ladd-Franklin (1847–1930) continued her studies at the school even though it was closed to women, and her later work on symbolic logic and visual optics was so well regarded that she merited an obituary in Science (21 March 1930, p. 307). Read more of Ladd-Franklin's story and those of other women mathematicians at this site from math professor Lawrence Riddle of Agnes Scott College in Decatur, Georgia. Brief biographies, some penned by students at the college, portray more than 190 numerically gifted women from as far back as the 6th century B.C.E.

  5. DATABASE: GPS for Proteins

    Where a protein hangs out and how it interacts with the cell's membranes furnish clues to its function. At LOCATE, researchers can track down both types of information for a standard set of more than 33,000 mouse proteins. To pinpoint molecules, computational cell biologist Rohan Teasdale of the University of Queensland in St. Lucia, Australia, and colleagues drew on their own experiments and data from the literature. Click on a cell map to find out which proteins congregate in the nucleus, mitochondria, and other organelles. The site also classifies proteins according to their relationship to cell and organelle membranes, such as whether they pass through a membrane once or snake through several times.
