Small, cheap gravity gadget to peer underground
Description: Researchers have built a small device that measures tiny fluctuations in gravity, and could be used to monitor volcanoes or search for oil. Such gravimeters already exist but compared to this new postage stamp-sized gadget, they are bulky and pricy. The new design is based on the little accelerometers found in smartphones. To begin with, the research team tested it by measuring the Earth's tides over a period of several days. [Source: BBC News]
