...class. In a unit encased by stainless steel, water flows through a "candle" of fine white clay eight inches long by two in diameter. Particles are caught in the candle, and the remaining water drains out via a spigot. Rural women, however, cant afford the system at some $25 per unit. Further, Sagara found...December Media Mighlights: GEOLOGY and GSA TODAY

...sity. "Viscosity is a measure of how well a liquid flows within stationary boundaries, like a pipe, in response to a given force," Woskov said. "It can indicate the chemistry and quality of a glass or metal product." The MilliWave Viscometer is special because it works at the temperatures of molten glass ......onductor in the sense of the speed at which charge flows through it," said Landman. "Under the best of circumstances, it is a slow conductor. Under most other circumstances, especially in dry form, it is simply an insulator." Beyond the conclusions, Schuster believes the work demonstrates the v...Researchers find glass-eating microbes at the rock bottom of the food chain
...preserved in the glassy margins of underwater lava flows (scientists call super-cooled lava spewed by undersea volcanoes "glass," which is similar to material used to make stone-age axes and knives). Glass samples were recovered by drilling as deep as four miles below sea level. "Weve documented how extens...Northern Vietnam drinking water contains dangerous arsenic levels
... shallow wells in the country, he said The problem flows largely from "tubewells," which pull water from depths of between approximately 30 feet and 120 feet, according to the researchers.

The high temperature causes the chemical to be released from the adsorbent material so it can be analyzed by a micro detector system.
