Research in the Andes examines rock glacier dynamics for mining industry

When it comes to mining for copper and gold, prospectors will move mountains to make it happen. As in, physically dig up the rock, extract the precious metals and move the debris elsewhere.

In the chilly high altitudes of the Andes Mountains, however, what may look like part of a mountain can in fact be a huge, frozen block of rock fragments and ice. When some of that ice melts in the spring, these so-called “rock glaciers” become a valuable source of water for local populations. (more…)

Stanford, CA — Plant roots are fascinating plant organs – they not only anchor the plant, but are also the world’s most efficient mining companies. Roots live in darkness and direct the activities of the other organs, as well as interact with the surrounding environment. Charles Darwin posited in The Power of Movement of Plants that the root system acts as a plant’s brain.

Due to the difficulty of accessing root tissue in intact live plants, research of these hidden parts has always lagged behind research on the more visible parts of plants. But now: a new technology–developed jointly by Carnegie and Stanford University–could revolutionize root research. The findings will be published in the large-scale biology section of the December issue of The Plant Cell. (more…)
