In vitro methanogenesis, microbial profile and fermentation of green forages with buffalo rumen liquor as influenced by 2-bromoethanesulphonic acid.
ABSTRACT: The interaction of fibre degrading microbes and methanogens was studied using two forages, lucerne (Medicago sativa) hay and maize (Zea mays) hay, as substrate and 2-bromoethanesulphonic acid (BES) as an additive in an in vitro gas production test. Gas and methane production (ml/g dry matter) were significantly higher...

Commentary: meat in a tube: cultured meat confronts agricultural pollution.
The question of buying meat becomes more complicated with each trip to the supermarket. With test tube meat a looming possibility, even vegetarians may want to reconsider their options. [ILLUSTRATION OMITTED] As it stands now, shoppers practically need a tutorial on the meat industry to...

GREEN BUZZ.
Byline: The Register-Guard Place settings can be borrowed for those large, local gatherings No reason to buy disposable plates because you lack the place settings to feed the 40 or 60 or 100 people headed to your next party. Eugene and Lane County...

For food's ecological impact, meat means more than miles: 'buying local' has small effect on greenhouse gases.
BUYING LOCAL CERTAINLY REDUCES THE miles food goes before we eat. But consumers aiming to shrink their ecological footprints will get more bang for their environmental buck by eating less red meat and dairy, reports a new study. The analysis finds that delivering food to the consumer accounts for...

Moving mountains: how do you protect a national park whose biggest threat comes from energy development in another country?
[ILLUSTRATION OMITTED] The sharp crack of splintering pine rouses me from a deep, restful sleep. Lifting out of my down sleeping bag, I watch Dan Weinberg take another swing of the axe. By the time I crawl out of my tent, the state senator from Montana has...

GAS ANALYZER HELPS CONVERT BIOGAS TO ELECTRICITY.
The ability of advanced, laser-based sensors to detect moisture, hydrogen sulfide and other contaminants in gases can smooth the way for biogas as a resource for electric utilities. Wouldn't it be great if some of the expensive Green Power programs you hear about actually worked? Experts and...

Antarctic ice tells tale of time with low carbon dioxide levels: core reveals temperature shifts over 800,000 years.
A kilometers-long ice core from Antarctica has recorded climate information for the past 800,000 years and has revealed three millennia during which carbon dioxide levels in the air were lower than any previously measured. The longest detailed records of atmospheric gases previously reported, from the uppermost sections...

Norwegian wails.
If a Norwegian-based pro-whaling lobby has its way, the environmentalists' rallying cry of "Save the Whales" will soon be changed to "Save the Whales ... for Lunch!" Norway and Japan, the two largest whaling nations in the world, are seeking new arguments to justify their break with...

Coal in your car's tank: American-dug coal could be altered to produce clean-burning fuels for our vehicles. Here's how we could do it, and what might stop it from happening.
In 1943, when Germany had virtually no sources of petroleum to fuel its Luftwaffe, U-boats, and Tiger tanks, its scientists (arguably among the best in the world at that time) didn't turn to solar and wind power. Evil does not equate to naivete. Hitler's technical advisers turned to another...

Dear EarthTalk: What is "cogeneration" as a means of providing heat and power?
Cogeneration--also known as combined heat and power, distributed generation, or recycled energy--is the simultaneous production of two or more forms of energy from a single fuel source. Cogeneration power plants often operate at 50 to 70 percent higher efficiency rates than single-generation facilities. In practical terms, what...
