Variety show. The single-base variations in human DNA that have become a gold mine for drug companies and disease researchers are the focus of the Human Genic Bi-Allelic Sequences Database, sponsored by a European consortium. The highly curated and annotated collection of single nucleotide polymorphisms (SNPs) culled from public databases expects to soon reach 50,000 entries.

Bug juice. Chemical ecology, particularly the pheromones and other chemicals that insects use to communicate (and that sometimes go into natural insect repellents), gets a close look at this researcher's site. There's a bibliography of over 11,400 insect pheromone papers, quizzes on chemical ecology, and sundry software for tasks such as modeling animal movement, teaching probabilities, and finding chemical vapor pressures.

Mothballed OTA. It was dismantled by the U.S. Congress 5 years ago, but the revered Office of Technology Assessment lives on at this Web site holding all 23 years of assessments and reports still useful as references, on everything from unconventional cancer treatments to invasive species to superefficient cars.
