Researchers find glass-eating microbes at the rock bottom of the food chain
... rock. Traces of this process are 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 l...
Wild plant or food plant?
... However, the production and purpose of these tiny glassy
structures common in plant tissues is poorly understood. Dolores Piperno at the Smithsonian Tropical Research Institute (STRI) in Panama and colleagues predict that a single genetic locus controls both lignin and phytolith production in squash (Cucur...

solids is the most popular approach for disposal. By spraying radioactive sludge into a high-temperature combustor, essentially all the water and other nonradioactive material could be removed, leaving only the radioactive metallic elements to be vi...
