Systems biology approach identifies nutrient regulation of biological clock in plants
Using a systems biological analysis of genome-scale data from the model plant Arabidopsis, an international team of researchers identified that the master gene controlling the biological clock is sensitive to nutrient status.   view more (2008-03-17)

Tunguska catastrophe: Evidence of acid rain supports meteorite theory
The Tunguska event is regarded as one of the biggest natural disasters of modern times. On 30 June 1908 one or more explosions took place in the area close to the Tunguska River north of Lake Baikal. The explosion(s) flattened around 80 million trees over an area of more than 2000 square kilometres.   view more (2008-07-16)

Researchers confirm benzene-like electron delocalization of important molecule
Researchers in the lab of University of Oregon chemist Shih-Yuan Liu have successfully synthesized and structurally characterized boron-nitrogen compounds that are isoelectronic and isostructural to the fundamentally important benzene molecule.   view more (2008-06-20)

Scientists show that streams are critical to preservation of oceanic coastal zones
The plight of the world's oceans is dire, according to recent studies, through insults from human-derived activities depopulating and damaging reefs, altering coastlines, and creating pollutants, such as nitrogen runoff from terrestrial watersheds.   view more (2008-03-13)

Contaminated soil pollution solution: herbicide eating bugs
Cancer-causing soil pollution from herbicide residues may be avoided in future thanks to researchers from Exeter University, who have identified bacteria which can break down a widely used toxic chemical, scientists will announce tomorrow (Thursday, 09 September 2004) at the Society for General... view more (2004-08-23)

Soil fungi affect parasitism of foliage-feeding insects
Recent studies have shown the importance of links between soil organisms and those feeding above-ground. However, to date these have involved two or three trophic levels, because it has been assumed that the effects weaken as one progresses up or down a food chain. In a forthcoming paper in Ecology... view more (2003-11-24)

Climate models need deeper roots, scientists say
By soaking up moisture with their roots and later releasing it from their leaves, plants play an active role in regulating the climate. In fact, in vegetated ecosystems, plants are the primary channels that connect the soil to the atmosphere, with plant roots controlling the below-ground dynamics.   view more (2005-12-06)

Will intensive forest practices impact water quality?
In order to increase productivity, forest practices have become more intense in recent decades. Forest fertilization increased by 800% in the southeastern United States from 1990 to 1999, and the total acreage fertilized in the Southeast exceeds the forest area fertilized in the rest of the world.   view more (2008-01-08)

Fat still on the children's menu
Parents should think twice before offering a low-fat menu to youngsters, despite concerns over obesity.   view more (2007-08-16)

Mandate for biofuels production requires science-based policy and global perspective
In his State of the Union Address on January 23, 2007, President Bush stated that, in order to substantially lower foreign oil imports, "We must increase the supply of alternative fuels, by setting a mandatory fuels standard to require 35 billion gallons of renewable and alternative fuels in... view more (2008-10-03)

Cooking with gas may increase inflammatory activity in the lungs
Cooking with gas may increase inflammatory activity in the lungs, suggests a study in Occupational and Environmental Medicine. Teflon filters were used to collect any particulate matter pollution emitted from gas and electric cookers. The residue was then applied to cultured cells that normally... view more (2001-02-10)

Arctic soil reveals climate change clues
Frozen arctic soil contains nearly twice the greenhouse-gas-producing organic material as was previously estimated, according to recently published research by University of Alaska Fairbanks scientists.   view more (2008-10-08)

Grasslands won't help buffer climate change as carbon dioxide levels rise
Because grasslands and forests operate in complex feedback loops with both the atmosphere and soil, understanding how ecosystems respond to global changes in climate and element cycling is critical to predicting the range of global environmental changes-and attendant ecosystem responses-likely to... view more (2005-08-09)

Methane found in desert soils bolsters theories that life could exist on Mars
Evidence of methane-producing organisms can be found in inhospitable soil environments much like those found on the surface of Mars.   view more (2005-11-01)

Carbon molecule with a charge could be tomorrow's semiconductor
Virginia Tech chemistry Professor Harry Dorn has developed a new area of fullerene chemistry that may be the backbone for development of molecular semiconductors and quantum computing applications.   view more (2008-09-09)

A rainbow of methods promises insights into biological processes and diseases
Physical alterations of DNA in chromosomes can cause serious diseases such as Down syndrome, Prader-Willi syndrome, or cancer.   view more (2007-05-02)

Geoscientists follow arsenic from chicken feed to streambeds
Organic arsenic is fed to poultry to prevent bacterial infections and improve weight gain. A little bit of arsenic is taken up by the tissue and the majority of it is excreted in urine.   view more (2005-10-12)

University of Oregon chemists discover new way to fix nitrogen
University of Oregon chemists have produced ammonia from nitrogen at room temperature under normal atmospheric pressure, marking a significant step toward achieving one of chemistry's coveted goals.   view more (2005-07-06)

Underwater Microscope Finds Biological Treasures in the Subtropical Ocean
Scientists towing an underwater digital microscope across the Atlantic have found possible missing links to the global nitrogen cycle, which in turn is linked to ocean productivity.   view more (2006-06-27)

Thawing permafrost likely to boost global warming
The thawing of permafrost in northern latitudes, which greatly increases microbial decomposition of carbon compounds in soil, will dominate other effects of warming in the region and could become a major force promoting the release of carbon dioxide and thus further warming, according to a new... view more (2008-09-02)

Replacing corn with perennial grasses improves carbon footprint of biofuels
Converting forests or fields to biofuel crops can increase or decrease greenhouse gas emissions, depending on where - and which - biofuel crops are used, University of Illinois researchers report this month.   view more (2008-12-03)

Legume compounds may help cancer treatment
The ARC Centre of Excellence for Integrative Legume Research (CILR) has lodged a complete patent application for compounds to treat cancer.   view more (2006-04-10)

Scientists find grass yield, carbon storage not affected by creepy-crawlies in the soil
New results from experiments at a unique ecology facility show that plant communities are dramatically altered by changes to the type of animal species living among their roots, but that key ecosystem measurements such as overall agricultural yield or the amount of soil carbon stored are... view more (2002-10-18)

Compost can turn agricultural soils into a carbon sink, thus protecting against climate change
Applying organic fertilizers, such as those resulting from composting, to agricultural land could increase the amount of carbon stored in these soils and contribute significantly to the reduction of greenhouse gas emissions.   view more (2008-02-25)

U-M scientists simulate effects of blowing Mars dust
Gusting winds and the pulsating exhaust plumes from the Phoenix spacecraft's landing engines could complicate NASA's efforts to sample frozen soil from the surface of Mars, according to University of Michigan atmospheric scientist Nilton Renno.   view more (2007-06-18)
