THE WOODLANDS, Texas – NASA’s Mars rover Curiosity has seen evidence of water-bearing minerals in rocks near where it had already found clay minerals inside a drilled rock.

Last week, the rover’s science team announced that analysis of powder from a drilled mudstone rock on Mars indicates past environmental conditions that were favorable for microbial life. Additional findings presented on March 18 at a news briefing at the Lunar and Planetary Science Conference in The Woodlands, Texas, suggest those conditions extended beyond the site of the drilling.

There’s a quality to David Meyer’s art that’s both conceptual and ephemeral, sort of like watching the clouds roll by.

You see with your mind, not your eyes. And even then, as with clouds, shapes move. Things change.

There’s art in distortion. (more…)

Searching for the “Perfect Glass”

Washington, D.C.— Glasses differ from crystals. Crystals are organized in repeating patterns that extend in every direction. Glasses lack this strict organization, but do sometimes demonstrate order among neighboring atoms. New research from Carnegie’s Geophysical Laboratory reveals the possibility of creating a metallic glass that is organized on a larger scale. Their results are published June 17 in Science.

Scientists have discovered glasses that demonstrate order among the nearest neighboring atoms, called short-range order, and a slightly wider range of atoms, called medium-range order. Most research about finding or creating a glass with a long-range, nearly crystalline, level of order—referred to as the perfect glass state—has been conducted on ice and the minerals silica and zeolite. But no research into long-range order glass has been successful until now. (more…)
