Citrus juice, vitamin C give staying power to green tea antioxidants
December 2, 2007 05:22 PM - Mario Ferruzzi, Purdue Newswire
WEST LAFAYETTE, Ind. - To get more out of your next cup of tea, just add juice. A new Purdue University study found that citrus juices enable more of green tea's unique antioxidants to remain after simulated digestion, making the pairing even healthier than previously thought.
The study compared the effect of various beverage additives on catechins, naturally occurring antioxidants found in tea. Results suggest that complementing green tea with either citrus juices or vitamin C likely increases the amount of catechins available for the body to absorb.
Expanding tropics could spur storms: study

WASHINGTON (Reuters) - Earth's tropical belt is expanding much faster than expected, and that could bring more storms to the temperate zone and drier weather to parts of the world that are already dry, climate scientists reported on Sunday.
Cutting forests for farmland 'yields meagre financial benefits'
December 1, 2007 03:38 PM - Ella Syafputri, SciDevNet
Nairobi, Kenya - Converting Indonesian forests and peatlands for various agricultural land uses has released huge amounts of greenhouse gases with little economic benefit, according to a new report.
The report, by the World Agroforestry Centre (ICRAF), the Center for International Forestry Research (CIFOR) and Indonesian partners, was released last week (21 November).
Data on changes in land use — such as deforestation for oil palm, rubber, coffee and mixed agroforestry — and carbon emissions in the provinces of East Kalimantan, Jambi, and Lampung were collected between 1990 and 2005.
Earth's dirty little secret: Slowly but surely we are skinning our planet
November 30, 2007 04:42 PM - University of Washington, Newswire
Seattle, WA - "It only takes one good rainstorm when the soil is bare to lose a century's worth of dirt." "It's more of a conceptual shift than anything else, but it's a conceptual shift that conserves the soil." Seattle, Washington - Throughout history civilizations expanded as they sought new soil to feed their populations, then ultimately fell as they wore out or lost the dirt they depended upon. When that happened, people moved on to fertile new ground and formed new civilizations.
That process is being repeated today, but in a new book a University of Washington geomorphologist argues the results could be far more disastrous for humans because there are very few places left with fertile soil to feed large populations, and farming practices still trigger large losses of rich dirt.
Abundant Evidence to Warn People Against GE Crops
November 30, 2007 08:25 AM -
There are thousands of toxic or allergic-type reactions in humans, thousands of sick, sterile, and dead livestock, and damage to virtually every organ and system studied in lab animals. Government safety assessments, including those of Food Standards Australia New Zealand (FSANZ), do not identify many of the dangers, and analysis reveals that industry studies submitted to FSANZ are designed to avoid finding them.
Manure Management Reduces Levels of Antibiotics and Antibiotic Resistance Genes
November 29, 2007 08:36 AM - American Society of Agronomy
Antibiotic resistance is a growing human health concern. Researchers around the globe have found antibiotics and other pharmaceuticals to be present in surface waters and sediments, municipal wastewater, animal manure lagoons, and underlying groundwater. In a recent article in the November-December issue of Journal of Environmental Quality, researchers at Colorado State University (CSU) describe a study to find out if animal waste contributes to the spread of antibiotics and antibiotic resistance genes (ARG), and if they can be reduced by appropriate manure management practices.
Limited biofuel feedstock supply?
November 29, 2007 08:23 AM - American Society of Agronomy
The United States has embarked on an ambitious program to develop technology and infrastructure to economically and sustainably produce ethanol from biomass. Corn stover, the above-ground material left in fields after corn grain harvest, has been identified as a primary feedstock. Stover and other crop biomass or residue is frequently referred to as "trash" or a waste, implying it has minimal value. However, when returned to the land, this carbon-rich material helps control erosion, replenishes soil organic matter, and improves soil quality. Organic matter in the soil retains and recycles nutrients and improves soil structure, aeration, and water exchange characteristics. In addition, organic matter is the energy source for the soil ecosystem.
Scotts to pay $500,000 fine over biotech bentgrass
November 26, 2007 08:20 PM - Reuters
WASHINGTON (Reuters) - Scotts Miracle-Gro Co will pay a $500,000 fine over allegations it failed to comply with U.S. rules while testing a genetically engineered grass variety that could one day be used on lawns and athletic fields, the Agriculture Department said on Monday.
The settlement involves field tests in Oregon and 20 other states of creeping bentgrass modified to resist weed killers such as Monsanto Co's Roundup. A golf course, for example, could be sprayed to kill weeds without hurting the grass. Genetically engineered grasses have not been approved by USDA.
Farmworkers Target Tobacco Giant After Deaths in the Fields
November 26, 2007 08:58 AM - Paul Abowd , Organic Consumers Association
"Workers say the hardest part of tobacco is the summer heat. Workers often aren't allowed a break, and the chances of heat sickness are high." Tobacco kills in many ways. Long before that first puff lies yet more lethality, hidden in the fields where the tobacco leaf is grown. Last year alone, heat stroke claimed nine North Carolina field workers.
Battle with industry leaves scars on Indian farmland
November 26, 2007 04:15 AM - Reuters
NANDIGRAM, India (Reuters) - It's the peak harvest season, but not a single sheaf of paddy grows on Abu Tayeb's land, testament to a hollow victory for farmers in eastern India who fought to keep big industry off their land but now face ruin.
