Analysis of Marcellus flowback finds high levels of ancient brines

December 20, 2012 – 5:05 am

Analysis of Marcellus flowback finds high levels of ancient brines - Brine water that flows back from gas wells in the Marcellus Shale region after hydraulic fracturing is many times more salty than seawater, with high contents of various elements, including radium and barium. The chemistry is consistent with brines formed during the Paleozoic era, a new study found.(10.1016/j.apgeochem.2012.10.002)

Photosynthesis: Mysterious enzyme structure solved

December 15, 2012 – 10:04 am

Photosynthesis: Mysterious enzyme structure solved - Scientists have solved a long-standing puzzle in photosynthesis research. With the aid of quantum chemistry they were able to provide unexpected insight into the properties of the oxygen evolving complex (OEC). The OEC is the catalyst in plants that splits water using sunlight in order to build carbohydrates, thus powering all life on earth. Its precise structure, which was showing enigmatic spectroscopic behavior, could now finally be solved with the aid of quantum chemistry.(10.1002/anie.201204705)
