Economist | "Much of [California's central valley] was an inland sea in its geological past," we read in the Economist, "and its alluvial soils and Mediterranean climate make parts of it, particularly the San Joaquin valley in the south, about the most fertile agricultural region in the world.

Popular Science | Undersea Cables Could Be Used as an Early Tsunami Detection System: "Monstrous tsunami waves, like the one that killed over 200,000 people in the Indian Ocean in 2004, create an electric field as they form. This field could possibly be sensed by a network of underwater sensors."

ABC | "U.S. military veterans are sorting through a massive government archaeological collection that has been neglected for decades, with the hope of archiving the stone tools, arrows and American Indian beads that were found beneath major public works projects."

Scientific American | Simulating the growth of the Tokyo subway system using slime mold: "A Japan-based research team found that if they placed bits of food (oat flakes) around a central Physarum polycephalum [slime mold] in the same location as 36 outlying cities around Tokyo, the mold created a network connecting the food sources that looked rather like the existing rail system."

Washington Post | "The gravelly beaches of Prince William Sound are trapping the oil [from the Exxon Valdez] between two layers of rock, with larger rocks on top and finer gravel underneath... creating a nearly oxygen-free environment with low nutrient levels that slowed the ability of the oil to biodegrade."

Financial Times | Stray dogs in Moscow are "evolving greater intelligence and wolf-like characteristics"—as well as an ability to use the subway.
