Chinese science express. The Bulletin of the Chinese Academy of Sciences, an English-language journal, now has a free Web site offering news updates on science in China. Recent stories covered a meeting on AIDS and an expedition to set up long-term environmental monitoring on a Himalayan peak.

Four seasons.

Environmental and earth science students can click on these color animations of global climate data to get a feel for the seasonal shifts in surface temperatures, precipitation, heat flux, winds, and other measurements.

Nothin' but mammals.

Ancient lemurs, rodents, dogs, tapirs, and other fossilized mammal species are cataloged in these two North American fossil mammal databases. The first site offers taxonomic and phylogenetic data on 3200 named species, while the second paleofaunal database includes clickable maps of fossil locations and trivia (such as the 10 smallest mammals and the most productive taxonomists).∼alroy/nafmsd.html∼alroy/nampfd.html

Wild ride.

The present best theory of what all matter boils down to, known as the Standard Model, is explained in the remarkably clear and simple pages of The Particle Adventure, a widely praised site aimed at high school students. Replete with animations of decays, quizzes, and a pop-up glossary, the site starts out by discussing quarks, leptons, and other particles, lays out the experimental evidence for them, then explains the workings of giant accelerators and detectors.

Genome scorecard.

Keep tabs on genome sequencing projects at the Genomes OnLine Database, which tracks the status of over 250 genomes—from Salmonella bacteria to the just-completed human chromosome 21. The links-packed site, which also includes viruses, phages, and organelles, recently found a new home with a company but will remain free.
