New insight into biochemical methane production
The biological sources of methane are wide-ranging; however, the conditions have to be always oxygen-free. Archaebacteria release the potent greenhouse gas in rice fields, mires and cows' stomachs, for example. ...

Japan extracts 'fire ice' gas from seabed
Japan said Tuesday it had successfully extracted methane hydrate, known as "fire ice", from its seabed, possibly unlocking many years' worth of gas for the resource-starved country.
Researchers shed light on ancient origin of life
(Phys.org) —University of Georgia researchers discovered important genetic clues about the history of microorganisms called archaea and the origins of life itself in the first ever study of its kind. Results of their study ...
Effect of CO2 on the integrity of well cement examined
Geologic carbon storage is the separation and capture of carbon dioxide (CO2) from large stationary sources, such as power plants, followed by injection into deep geologic formations. Long-term storage of ...
New tool for measuring frozen gas in ocean floor sediments
A collaboration between the National Oceanography Centre (NOC) and the University of Southampton is to develop an instrument capable of simulating the high pressures and low temperatures needed to create ...
Tunguska, 1908: Russia's greatest cosmic mystery
The stunning burning-up of a meteor over Russia on Friday that unleashed a shockwave injuring hundreds of people appears to be the country's most dramatic cosmic experience since the historic Tunguska Event ...
Researchers use combustible gases to power leaping robots
They can already stand, walk, wriggle under obstacles, and change colors. Now researchers are adding a new skill to the soft robot arsenal: jumping.
Wetland trees a significant overlooked source of methane, study finds
Wetlands are a well-established and prolific source of atmospheric methane. Yet despite an abundance of seething swamps and flooded forests in the tropics, ground-based measurements of methane have fallen well short of the ...
