New research indicates a 'troubled' greenhouse is brewing

...rocarbon pollution of the atmosphere, this natural methane oxidized to carbon dioxide and created a global greenhouse event," he explains. "The past methane outburst dwarfed even human consumption of hydrocarbons, and there is a danger that another similar ...

Hydrogen and methane provide raw energy for life at 'Lost City'

...s, Lost City microbes appear to live off bountiful methane and hydrogen. Absent is carbon dioxide, the key energy source for life at black-smoker vents. And there is little hydrogen sulfide and only very low traces of metals, on which many of the microbes at the other kind of vents depend. The difference in ...

It's electric: Cows show promise as powerplants

...ce isn't a new idea : some farmers already use the methane released by livestock waste to power machinery and lights. But converting methane into electricity requires costly equipment : one California farmer reportedly spent $280,000 to conv...

Discovering an ecosystem beneath a collapsed Antarctic ice shelf

...net's crust. Domack and his coauthors propose that methane from deep underwater vents likely provide the energy source capable of sustaining the chemical life at the observed 850-meter [approximately 2800-foot] depth. Such extreme cold-vent regions have previously been found near Monterey, California, where...

World-first technology enables study of ancient bacteria

...bacteria on Earth. Some of these bacteria produce methane that accumulates in "gas hydrates" ?a super concentrated methane ice that contains more carbon than all conventional fossil fuels and, therefore, a potentially enorm...

Science's Breakthrough of the Year: Watching evolution in action

...rld where infrequent but drenching rains of liquid methane shape the land and participate in a fascinating hydrologic cycle. A Rich Year for Plants: Several key molecular cues behind flowering and other plant mysteries and surprises came to light in 2005. For example, plant molecular biologists pinned down ...

Amazonian terra preta can transform poor soil into fertile

... for thousands of years and substantially reducing methane and nitrous oxide emissions from soils. "The result is that about 50 percent of the biomass carbon is retained," Lehmann said. "By sequestering huge amounts of carbon, this technique constitutes a much longer and significant sink for atmospheric car...

Earth Rx: A microbial biotechnology prescription for global environmental health

...ever, they also can generate useful fuels, such as methane and hydrogen, and we are pursuing research on all of these renewable-energy forms." Rittmann believes the key to achieving success through microbial ecology and biotechnology is to take advantage of microbial diversity as much as possible, particu...

Carbon cycle was already disrupted millions of years ago

...that large quantities of 12C in the form of CO2 or methane were suddenly released into the atmosphere. This could have been the result of methane being released from gas hydrates which were buried in the ocean floor. It is not clear which mechani...

Plants used to detect gas leaks, from outer space!
