Scientists worry that rising global temperatures accompanied by melting permafrost in arctic regions will initiate the release of underground methane into the atmosphere. Once released, that methane gas would speed up global warming by trapping the Earth's heat radiation about 20 times more efficiently than does the better-known greenhouse gas, carbon dioxide. An MIT paper appearing in the Journal of Geophysical Research online Aug. 29 elucidates how this underground methane in frozen regions...

Researchers at MIT recently found an elegant solution to a sticky scientific problem in basic fluid mechanics: why water doesn't soak into soil at an even rate, but instead forms what look like fingers of fluid flowing downward.Scientists call these rivulets "gravity fingers," and the explanation for their formation has to do with the surface tension where the water"”or any liquid"”meets the soil (or other medium). Knowing how to account for this phenomenon mathematically will...

Greenhouse gases injected underground? It's new way to significantly cut the amount of carbon dioxide that reaches the atmosphere and spurs global warming, according to MIT engineers. Although promising, the technique has never been tested in a full-scale industrial operation. However, MIT engineers have developed a software tool to determine how much CO2 can be sequestered safely in geological formations. The work will be presented Wednesday, Nov. 18 at the 9th International Conference on...
