  1. DATABASE: Proteins at Home

    The protein Nsp1 forms part of the nuclear pore, the channel that passes through a cell's nuclear membrane. The molecule usually hangs out at the rim of the nucleus. Track down Nsp1 and more than 30,000 other proteins with Organelle DB, started by molecular biologist Anuj Kumar of the University of Michigan, Ann Arbor. You can search protein localization data for 138 species, including lab stalwarts such as Drosophila and Caenorhabditis elegans and more exotic creatures such as the pygmy chimp Pan paniscus. Using information from the Kumar lab's experiments, the literature, and other databases, the site narrows each protein's whereabouts among more than 50 organelles and other cellular locales. Launch the new Organelle View feature to map your favorite yeast proteins on a three-dimensional cell model.

  2. DATABASE: The Planet's Medical Chart

    If you want to find out which countries recorded the most cholera cases last year or compare measles vaccination rates, drop by the Global Health Atlas from the World Health Organization. The site emphasizes communicable diseases, but its cache of health statistics covers variables as diverse as child mortality and number of hospital beds per capita. Last year, for instance, Senegal reported the most cholera cases, nearly 32,000. And Bahrain ranks highest in measles vaccination levels at 100%—versus 93% in the United States and only 80% in the United Kingdom. A library houses a host of maps, or you can use the site's data to make your own charts. Included is a map showing the breakdown of world tuberculosis cases in 2004, with red indicating the countries with the most infections.

  3. AUDIO: Tuning In Biomedical Research

    National Institutes of Health Radio doesn't have forced banter or weather reports, but it does furnish short audio reports about new research funded by NIH, health advice, and other medical matters. You can listen to the programs, which some radio stations also broadcast, at this site. Recent topics include gene therapy to combat melanoma and the U.S. Food and Drug Administration's approval of the first permanent artificial heart. A new set of stories goes online each Friday. For longer programs, check out NIH's podcasts.

  4. EXHIBIT: Life in the Volcano

    The searing, acidic waters of the Uzon Caldera on Russia's Kamchatka Peninsula are paradise for microorganisms such as colorful bacteria and algae. At this new exhibit from the Exploratorium in San Francisco, visitors can tag along with U.S. and Russian researchers who choppered into the remote collapsed volcano last year. The scientists narrate slideshows about their work on extremophiles. One group, for instance, is studying traces that modern bugs leave in the minerals that precipitate around hot springs. They hope to find ways to more easily identify microbial remains in ancient rocks—and possibly in extraterrestrial samples.

  5. DICTIONARY: Physics Law School

    Unlike Rome at rush hour, the universe is a lawful place. Rules govern everything from the relation between a gas's pressure and volume to the speed at which galaxies recede from Earth. Catch up on physics jurisprudence with The Laws List from Erik Max Francis, a programmer in San Jose, California. For example, Lambert's first law relates the amount of illumination falling on a surface to its distance from the light source. The site also serves as a physics glossary, offering brief explanations of terms and ideas.
