Methane News

flame 13th December 2007 Methanogen Mining
Steve Larter and colleagues at the University of Calgary, Alberta, have reported a mechanism by which methanogenic bacteria can convert hard-to-extract oil into methane for recovery.

crops 17th December 2006 Shallow Methane
Michael Riedel and colleagues at McGill University in Montreal have reported their discovery of methane hydrates at much shallower depth than expected during their research expedition in 2005.

biomass burning 23rd November 2006 Methane Slow-down
Sherwood Rowland, of the University of California, and colleagues, have reported that the previously rapid rise in atmospheric methane concentrations has slowed down markedly in recent years.

cows 15th October 2006 Burping Cows
David Beever and colleagues at the feed producer Keenan and Co. have again highlighted the great potential for reducing methane emission from cattle through changes in the compostion of their feed.
