Methane Sources on Mars

Although the presence of methane in Mars' atmosphere has been positively identified more than four years ago by three different sources, its provenience still eludes scientists. On Earth, we have the biomass to blame, namely the decaying plants and animal flatulence, but since none of these exists on Mars, a viable explanation has to be found. A product of some ancient life process, persisting in the atmosphere, is also out of the question, as recent research has demonstrated that methane is quickly decomposed by sunlight and cannot last for more than a few hundred years.

Growing Plants And Trees On dumps Could Help Save The Planet

Landfill sites produce the greenhouse gases, methane and carbon dioxide, as putrescible waste decays. Growing plants and trees on top of a landfill, a process known as 'Phytocapping', could reduce the production and release of these gases, according to Australian scientists writing in a forthcoming issue of International Journal of Environmental Technology and Management.

Eat grass, more gas

Contrary to the previously held belief, researchers at the University of Manitoba have discovered grain-fed cows produce less methane than cattle that feast on grass.

Penn State Off Hook In Chemist's Patent Suit

Law360, New York (November 14, 2008) -- A Florida judge has dismissed a patent case from a chemist who alleged that a Pennsylvania State University research department stole his process for converting methane gas into liquid.

Cassini Could Find Signs of Life on Enceladus

New Scientist reviews the possibility that the Cassini probe might be repurposed to look for signs of life on Saturn's enigmatic moon Enceladus. "[Enceladus' water vapor] plume's origin is still being debated, but some models suggest the moon holds an ocean of liquid water beneath its surface. This ocean could be a potential habitat for extraterrestrial life. ... Though the probe was never designed to look for life, it could do so by studying organic chemicals such as methane in the plume, the team says."
