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.

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.
