g Stars - A puzzlingly regular waxing and waning of Earth's biodiversity may ultimately trace back to our solar system's bobbing path around the Milky Way, a new study suggests. See article.
g Abodes - The Cassini spacecraft has found possible ice volcanoes on Saturn's moon Titan. The unique moon continues to teach astrobiologists about the evolution of rocky bodies around giant planets and is helping scientists understand if such worlds could support habitable environments. See article.
g Life - Experiments by a team of researchers in New York and New Jersey have generated evidence that questions the common belief that the pterygotid eurypterids ("sea scorpions") were high-level predators in the Paleozoic oceans. This group, which ranged the seas from about 470 to 370 million years ago (long before the dinosaurs appeared), included the largest and, arguably, scariest-looking arthropods known to have evolved on planet Earth. See article.
g Cosmicus - SPACE.com recently chatted with astronomer Chris Impey about what the future has in store, and whether we should fear it. See article.
g Aftermath - Would dutiful American citizens trust the government to handle first contact with extraterrestrials and rush to get information to the public? See article. This article is from 1999.
