"Infrasonic Symphony" Intrigued by reports of tsunami-avoidance behavior in Sri Lankan wildlife? Science News offers a timely antidote to simplistic mumbo-jumbo about the "mythical power" of animal earthquake detection with a detailed look at the latest research into low-frequency sound. The Elephant Listening Project is particularly interested in elephant rumblings that produce Rayleigh waves. "Mammals, birds, insects, and spiders can detect Rayleigh waves," notes The Explainer.

Bus-size jade boulders found in Guatemala Great NY Times story [Google'd here] of archeologists tracking down a mother lode of translucent blue jade after it was exposed by a hurricane. The vein solves the mystery of where the ancient Olmecs got the jade for beautiful carvings like these. Olmec civilization, famous for its colossalstoneheads, is itself considered something of a mother lode for later Central American peoples like the Maya. Meanwhile, some scientists in Guatemala are digging up things that are much less fun than jade.
