Researchers at the Energy Biosciences Institute (EBI) at the University of Illinois have discovered widespread occurrence of plant-parasitic nematodes in the first reported nematode survey of Miscanthus and switchgrass plants used for biofuels. Lead researcher Tesfamariam Mekete, a U of I post-doctoral research associate, said the team's first step was to identify potential pathogenic nematodes of these top two energy-yielding cellulosic-ethanol feedstock plants. "Nematodes are a part of our...

MADISON, WI -- The emergence of biofuels into agricultural systems presents new opportunities for farmers to improve economic return while providing critical ecosystem services. Integrating perennial crops can help meet food, fuel and fiber needs, but will require an understanding of biomass productivity on specific landscape positions and environments. To diversify their farms, farmers will need to know where their crops will give them the best yield. Landscape processes, such as hill slope...

New report outlines trade-offs of biofuel production The development of alternative fuel will greatly benefit the U.S., say scientists in an Energy Foundation-funded report published today by the Ecological Society of America (ESA), the nation's largest organization of ecological scientists. However, in order to effectively reap the social and economic benefits of biofuel production, U.S. policies need to address potential effects of land-use choices on our ecosystems. In the report,...

VONORE, Tenn., Feb. 1 /PRNewswire/ -- One of the world's first cellulosic ethanol demonstration plants has opened near Vonore, Tennessee, and has begun producing ethanol -- marking what Gov. Phil Bredesen calls "an important step forward" in the race to reduce dependency on fossil fuels. The $50 million facility is expected to have an output of 250,000 of ethanol annually and serve as a testing ground for new technologies that can be used in larger scale production. A partnership of...

Diverse biofuel plantings such as native prairie attract more beneficial insects than do single crops such as corn, Michigan State University scientists find. Therefore, biofuel policies should take such added value into account, they urge, based on their pioneering studies of beneficial insects in biofuel crops. Lady beetles, bees and other beneficial insects provide numerous ecosystem services, including controlling pests and pollinating crops. Earlier research by MSU scientists estimated...

With many companies investing heavily in algae-based biofuels, researchers from the University of Virginia's Department of Civil and Environmental Engineering have found there are significant environmental hurdles to overcome before fuel production ramps up. They propose using wastewater as a solution to some of these challenges. These findings come after ExxonMobil invested $600 million last summer and the U.S. Department of Energy announced last week that it is awarding $78 million in...

THOUSAND OAKS, Calif., Nov. 24 /PRNewswire/ -- Energy crop company Ceres, Inc. announced today that it is working with CHOREN, an international leader in Biomass to Liquids technology, to optimize energy crops for thermochemical conversion to advanced low-carbon biofuels. The two-year bioenergy project is funded in part by a grant from the U.S. Department of Energy. The thermochemical process does not require enzymes or microorganisms; instead, the biomass is gasified under certain heat...

Biomass feedstock nitrogen study compares four grasses; switchgrass is most efficient. A USDOE and USDA study concluded that 50 million U.S. acres of cropland, idle cropland, and cropland pasture could be converted from current uses to the production of perennial grasses, such as switchgrass, from which biomass could be harvested for use as a biofuel feedstock. Economically viable production of a perennial grass monoculture from which substantial quantities of biomass are removed annually is...


Word of the Day
attercop
  • A spider.
  • Figuratively, a peevish, testy, ill-natured person.
'Attercop' comes from the Old English 'atorcoppe,' where 'atter' means 'poison, venom' and‎ 'cop' means 'spider.' 'Coppa' is a derivative of 'cop,' top, summit, round head, or 'copp,' cup, vessel, which refers to 'the supposed venomous properties of spiders,' says the OED. 'Copp' is still found in the word 'cobweb.'
