Anatomy of a quake. It's been 10 years since the Loma Prieta earthquake rocked northern California, and the San Francisco Exploratorium is marking the occasion with a tour of the science of the San Andreas fault. Webcast visits from 9 to 17 October will include a seismology lab, trenches dug across the fault, and a huge drill used to study crustal stresses. www.exploratorium.edu/faultline/share.html

Earth in the balance sheet. One of the hottest areas in environmental science is “ecological economics,” which probes the interplay of commerce and ecosystem health. A new online article in the journal Conservation Ecology features a computer model for exploring such trade-offs. The model lets participants assume the guise of farmers or land managers, whose competing interests determine how much phosphorus—a byproduct of fertilizer use that spurs algal growth—gets dumped into a lake. Too much and you can kiss those fish goodbye. www.consecol.org/Journal/vol3/iss2/art4

Dino-mite. Dinosaur fans won't want to miss this fact-packed BBC home page featuring remarkably lifelike video clips of creatures such as Peteinosaurus (a flying lizard) and Postosuchus (a 6-meter-long carnivore). The site accompanies a TV series airing this fall. www.bbc.co.uk/dinosaurs
