Hitchhiking bacteria could compromise the detection of life on Mars
Is there life on Mars? It's possible, but it may not be Martian, say scientists. New research, published in the open access journal BMC Microbiology, suggests that conditions on Mars are capable of supporting dormant bacteria, known as endospores. This raises concern about future attempts to detect Martian life forms because endospores originating... view more... (2003-04-03)
Soil-bound prions that cause CWD remain infectious
Scientists have confirmed that prions, the mysterious proteins thought to cause chronic wasting disease (CWD) in deer, latch on tightly to certain minerals in soil and remain infectious. view more (2006-04-14)
Golf course putting greens show their age
Just like the rest of us, golf courses show their age-especially on putting greens, which experience more foot traffic than anywhere else on golf courses. Putting greens, which comprise only about 1.6% of the total area on most courses, require more intensive management than any other part of the course. view more (2009-09-04)
Chemically-conscious gardeners use bugs to beat back the weeds â€" Microbiology Today: May 2005 issue
Organic gardeners can control pesky weeds with the help of some common soil microbes, according to an article in the May 2005 issue of Microbiology Today, the quarterly magazine of the Society for General Microbiology. view more (2005-04-26)
Emphasizing the 'precision' in precision agriculture
New protocol and software developments are helping farmers put the precision back in "precision agriculture" by making it easier for growers to use previously ineffectual soil and environmental data to manage their crops. view more (2007-09-27)
A computer simulation tool that predicts the influence of forest clearings on soil fertility
The process of clearing consists of cutting down trees in such a way that those remaining have more resources and can grow more. The question was if too many had been cut down, with the concomitant removal of nutrients, and the manner, therefore, in which this process might affect long-term soil fertility. view more (2004-09-08)
New Method Confirms Importance of Fungi in Arctic Nitrogen Cycle
A new method to calculate the transfer of nitrogen from Arctic mushrooms to plants is shedding light on how fungi living symbiotically on plant roots transfer vital nutrients to their hosts. view more (2006-05-10)
Climate change triggered dwarfism in soil-dwelling creatures of the past
Ancient soil-inhabiting creatures decreased in body size by nearly half in response to a period of boosted carbon dioxide levels and higher temperatures, scientists have discovered. view more (2009-10-07)
Thawing permafrost a significant source of carbon
Permafrost, permanently frozen soil, isn't staying frozen and a type of soil called loess contained deep within thawing permafrost may be releasing significant, and previously unaccounted for, amounts of carbon into the atmosphere. view more (2006-06-16)
ESA and EADS-CASA sign contract to build instrument for the SMOS mission
A significant milestone in the development of ESA's Soil Moisture and Ocean Salinity (SMOS) mission was reached last week when the contract to build the payload was signed between ESA and EADS (European Aeronautic Defence and Space Company)-CASA from Spain. The contract, worth 62 million euros, was signed in Madrid, Spain on 11 June 2004 at the... view more... (2004-06-17)
Long-term study of orchard ground cover management systems
Orchard floor and groundcover management is important to fruit growers, affecting the efficiency of orchard operations, fruit tree performance, and soil quality. view more (2009-02-27)
Abertay researchers in clover to unearth destructive bug
Scots scientists are playing a key role in a major new research effort which could save Britain's farmers millions of pounds a year through reductions in fertiliser and pesticide use. Biotechnology experts at the University of Abertay Dundee, in partnership with two organisations in England, have been awarded £471,000 by the BBSRC... view more... (2002-04-04)
Increase in ethanol production from corn could significantly impact
If projected increases in the use of corn for ethanol production occur, the harm to water quality could be considerable, and water supply problems at the regional and local levels could also arise, says a new report from the National Research Council. view more (2007-10-11)
Warming could free far more carbon from high Arctic soil than earlier thought
Scientists studying the effects of carbon on climate warming are very likely underestimating, by a vast amount, how much soil carbon is available in the high Arctic to be released into the atmosphere, new University of Washington research shows. view more (2005-12-06)
FSU classics professor exploring a 'lost' city of the Mycenaeans
Along an isolated, rocky stretch of Greek shoreline, a Florida State University researcher and his students are unlocking the secrets of a partially submerged, "lost" harbor town believed to have been built by the ancient Mycenaeans nearly 3,500 years ago. view more (2008-03-12)
Africa`s deserts are in retreat
AFRICA`S deserts are in retreat. Burkina Faso, one of the West African countries devastated by drought and advancing deserts 20 years ago, is growing greener again - so much so that families who fled to wetter coastal regions are starting to go home. New research confirming this remarkable environmental turnaround in one of Africa`s most arid... view more... (2002-09-20)
Bran filters chlorinated hydrocarbons and arsenic out of waste water
Compounds of arsenic and hexachlorocyclahexane (HCHs) previously occurred above all in the production of pesticides. Pesticides containing HCHs have been prohibited in Germany since the 1980s. Arsenic is still used in the semiconductor and glass industries and pollutes water and the soil in many places. Since HCHs and arsenic are carcinogenic... view more... (2002-10-11)
Organic Soils Continue to Acidify Despite Reduction in Acidic Deposition
Following the Clean Air Act Amendments of 1970 and 1990 acidic deposition in North America has declined significantly since its peak in 1973. Consequently, research has shifted from studying the effects of acidic deposition to the recovery of these aquatic and terrestrial ecosystems. view more (2009-01-13)
Rainforest rehab in every sense
Sophisticated sensors that measure leaf wetness, soil moisture and temperature are helping rehabilitate rainforest in the Springbrook World Heritage precinct in south-east Queensland. view more (2009-06-12)
A new plant-bacterial symbiotic mechanism promising for crop applications
The growth of most plants depends on the presence of sufficient amounts of nitrogen contained in the soil. However, a family of plants, the legumes, is partially free of this constraint thanks to its ability to live in association with soil bacteria of the Rhizobium, genus, capable of fixing nitrogen from the air. view more (2007-06-06)
