Fracking leaks may make gas 'dirtier' than coal

(PhysOrg.com) -- Extracting natural gas from the Marcellus Shale could do more to aggravate global warming than mining coal, according to a Cornell study published in the May issue of Climatic Change Letters (105:5).

Light pulses can behave like an exotic gas

In work published in Science, the team led by Prof. Dr. Ulf Peschel reports on measurements on a sequence of pulses that travel thousands of kilometers through glass fibers that are only a few microns thin. The researchers ...

New contaminants found in oil and gas wastewater

Duke University scientists have discovered high levels of two potentially hazardous contaminants, ammonium and iodide, in wastewater being discharged or spilled into streams and rivers from oil and gas operations in Pennsylvania ...

Analysis of fracking wastewater yields some surprises

Hydraulically fractured natural gas wells are producing less wastewater per unit of gas recovered than conventional wells would. But the scale of fracking operations in the Marcellus shale region is so vast that the wastewater ...
