Cornell University scientists have characterized the genome of a metal-loving bacteria with an affinity for rare earth elements. The research paves the way towards replacing the harsh chemical processing of these elements with a benign practice called biosorption.
The microbe selectively adsorbs -- or clings -- to these rare earth elements, making it an ideal candidate to carry out an eco-friendly purification procedure. "Our process potentially would be significantly less land- and capital-intensive to build," Medin said,"as our separations could be done with repeated enrichment through columns full of immobilized bacteria instead of mixer-settler plants that are miles long."Funding for this research was provided by Cornell Atkinson, the Burroughs Wellcome Fund, the Advanced Research Projects Agency-Energy , part of the U.S.

Research: Electrons in a strange metal worldImagine a flock of birds as they wheel across the sky: surging into a mass, flowing into ribbons that twist and turn again into fantastic shapes. If you follow one bird within the flock, you can describe its actions, the way it flaps its wings or uses its tail to brake. Yet, even if you could minutely account for the behavior of each individual bird, the shapes and patterns of their collective flight would still evade understanding.
