>Chip-Scale Magnetic Sensor Draws on Mini Clock Design (LinuxElectrons)
A low-power, magnetic sensor about the size of a grain of rice that can detect magnetic field changes as small as 50 picoteslas a million times weaker than the Earth's magnetic field has been demonstrated by researchers at the National Institute of Standards and Technology (NIST). Described in the Dec. 27 issue of Applied Physics Letters,* the device can be powered with batteries and is about 100

JOHN C. CAL-WHO? One hundred and seventy-two years ago Tuesday, John C. Calhoun of South Carolina resigned from the vice presidency, a job he had held under John Quincy Adams and Andrew Jackson. Calhoun, largely forgotten by history, was a states-righter who bristled at any attempts to end slavery and at federal laws designed to oversee his beloved Palmetto State. The hardened attitudes of
