As if the nation's overexcited and misguided border vigilantes didn't have enough ways to trigger alarms and bedevil the U.S. Border Patrol (whose job is hard enough as it is), University of Arizona researchers have developed Helios, a monitoring system that uses an acoustic sensor to detect movement via fiber optic cables buried beneath the US-Mexico border.
