A tiny Micro-Electro-Mechanical System (MEMS) accelerometer used in smart phones to adjust the orientation of the screen could serve to create a real-time urban seismic network and increase the amount of strong motion data collected during a large earthquake, according to a new paper in the Bulletin of the Seismological Society of America.

Since the 1990s, (MEMS accelerometers have been measure the rate of acceleration of ground motion and vibration of cars, buildings and installations. They revolutionized the automotive airbag industry and are found in many devices used daily, including smart phones, video games and laptops.

The Affordable Care Act is not quite ready, some of the key aspects won't be available and many large corporations are still exempt, but it is rolling out for individuals tomorrow. 76% of U.S. adults are aware of the law's individual mandate - they know the law will require them to have insurance or pay penalties - but only 40% are aware that new health insurance marketplaces are (in many cases) opening on October 1, or that financial assistance that is available to help people with low or moderate incomes pay their health insurance premiums.
