A paper by a Rice team expands upon previous research to locate and quantify the amount of methane hydrates -- a potentially vast source of energy -- that may be trapped under the seabed by analyzing shallow core samples. The paper published this week by the Journal of Geophysical Research -- Solid Earth should silence the skeptics, the researchers said.

 | As the US Environmental Protection Agency weighs whether to define coal ash as hazardous waste, a Duke University study identifies new monitoring protocols and insights that can help investigators more accurately measure and predict the ecological impacts of coal ash contaminants. ...> Full Article |
 | A new technology for removing water from ultrafine coal slurry has been successfully tested at the commercial scale at an operating coal cleaning plant. The technology offers the possibility of reducing the coal slurry impoundment problem from the source. ...> Full Article |
Scientists from the Field Museum in Chicago and Royal Holloway University of London publishing their results this week in the journal Nature Geoscience have shown that the amount of charcoal preserved in ancient peat bogs, now coal, gives a measure of how much oxygen there was in the past.

 | The volcanic eruptions thought responsible for Earth's largest mass extinction -- which killed more than 70 percent of plants and animals 250 million years ago -- is still taking lives today. That's the conclusion of a new study showing, for the first time, that the high silica content of coal in one region of China may be interacting with volatile substances in the coal to cause unusually high rates of lung cancer. The study appears in ACS' Environmental Science & Technology. ...> Full Article |
Worldwide, thousands of workers die every year from mining accidents, and instantaneous coal outbursts in underground mines are among the major killers. But although scientists have been investigating coal outbursts for more than 150 years, the precise mechanism is still unknown.
