Channel surfing. The Internet's sprawling ion channel resources may seem overwhelming, but this Web page leads to several choice sites, including databases, images, and course material.
Curling up with cosmo. If the cosmological constant sounds intriguing but way intimidating, pay a visit to the Cosmology Tutorial, which explains cosmology at a high school math level. The site answers questions like “Where is the center of the big bang?” and includes bulletins on the latest cosmology news.
Diversity depot. Chemistry is being transformed by the combinatorial approach—using molecular building blocks to create vast libraries of molecules that may hold useful compounds. Combinatorial chemists can keep up with this fast-moving field at the Diversity Information Pages, which track patents, articles, symposia, jobs, and more. www.5z.com/divinfo
Microbial soup. Want to compare your Haemophilus influenzae gene to that in some other bug, or bone up on microbial genomes in general? From sulfur-eating Archaeoglobus fulgidus to Yersinia pestis, which causes plague, The Institute for Genomic Research's Microbial Database takes you to the Web sites of the world's microbial genome projects—18 published and more than 60 in progress. www.tigr.org/tdb/mdb/mdb.html
Quantum cache. It may seem like science fiction, but researchers this year showed that teleportation—on a quantum scale—can be done. This page at Los Alamos National Lab offers an introduction to quantum computing and cryptography, as well as a slew of outside links, including labs that made headlines this year.
