Chicken, beams and chips: New technique enables rapid detection of bacterial contamination of meat products
Researchers at the University of Wales, Aberystwyth (UWA) have developed a new rapid procedure which will enable food producers to detect the bacterial contamination of their meat products. Their findings, published this week in Applied and Environmental Microbiology1 (Vol. 68, No.6 June 2002, p.2822 - 2828) demonstrate a novel analytical... view more... (2002-06-10)
Plant protein 'doorkeepers' block invading microbes, study finds
A group of plant proteins that "shut the door" on bacteria that would otherwise infect the plant's leaves has been identified for the first time by a team of researchers in Denmark, at the University of California, Davis, and at UC Berkeley. view more (2009-06-29)
Thale cress goes on the defensive
Thale cress has a complicated defence technique against insects and microorganisms that use the plant as a source of food. view more (2007-05-15)
Test finds manufactured nanoparticles don't harm soil ecology
The first published study on the environmental impact of manufactured nanoparticles on ordinary soil showed no negative effects, which is contrary to concerns voiced by some that the microscopic particles could be harmful to organisms. view more (2007-03-23)
A common genetic mechanism discovered in nitrogen-fixing plants
Some soil microorganisms are capable of forging associations with plant roots in the form of symbioses. Certain of these relationships play a highly important ecological and agronomic role. view more (2008-03-11)
New petroleum-degrading bacteria found at Rancho La Brea Tar Pits in Los Angeles
Environmental scientists at UC Riverside have discovered that the Rancho La Brea tar pits in downtown Los Angeles, Calif., house hundreds of new species of bacteria with unusual properties, allowing the bacteria to survive and grow in heavy oil and natural asphalt. view more (2007-05-11)
MIT biologists solve vitamin puzzle
Solving a mystery that has puzzled scientists for decades, MIT and Harvard researchers have discovered the final piece of the synthesis pathway of vitamin B12—the only vitamin synthesized exclusively by microorganisms. view more (2007-03-23)
Earth Rx: A microbial biotechnology prescription for global environmental health
Water. Waste. Energy. This trio of problems is among the greatest challenges to the environmental health of society. Water purification alone is becoming more problematic in the world due to our increasingly reliance on contaminated sources, such as polluted rivers, lakes and groundwater. view more (2006-02-16)
Pilot study reinforces use of portable anteroom HEPA filtration
Amidst an increase in new tuberculosis cases, researchers have begun investigating the effectiveness of new operating room filtration systems designed to protect staff and patients. view more (2008-05-07)
Corrosion-inhibiting coatings containing 'good' bacteria
A new, environmentally friendly coating that protects metals against corrosion in seawater has been developed by a team of researchers from Sheffield Hallam University. view more (2009-03-30)
Scientists find how amber becomes death trap for watery creatures
Shiny amber jewelry and a mucky Florida swamp have given scientists a window into an ancient ecosystem that could be anywhere from 15 million to 130 million years old. view more (2007-10-19)
Inflammation contributes to colon cancer
Researchers led by Drs. Lillian Maggio-Price and Brian Iritani at The University of Washington found that mice that lack the immune inhibitory molecule Smad3 are acutely sensitive to both bacterially-induced inflammation and cancer. They report these findings in the January 2009 issue of The American Journal of Pathology. view more (2009-01-22)
Rushing fireball developed its own form of sugar digestion
Microbiologists from Wageningen have discovered a strange form of digestion in an exotic microorganism. The rushing fireball, Latin name Pyrococcus furiosus, has reinvented the wheel for several steps of sugar digestion. Pyrococcus furiosus, which was discovered 15 years ago on an Italian volcanic island, digests sugar somewhat differently from... view more... (2002-04-18)
Scientists seek to assess the microbial risks in the water we drink
It is a familiar scenario experienced around the world: an outbreak of gastrointestinal illness suddenly emerges in a community, and no one knows where it came from or how to stop it. At the start of the outbreak, only a few people are affected, most often the very old and the very young. view more (2007-12-12)
Protein clue to tailor-made antibiotics
Scientists at the University of York have made a huge leap forward in the search for 'smarter' antibiotics. view more (2006-08-23)
Innovative Research Technique Reveals Another Natural Wonder in Yellowstone Park: A Unique, Photosynthesizing Life-Form
In the hot springs of Yellowstone National Park, a team of researchers partially funded by the National Science Foundation (NSF) discovered a new bacterium that transforms light into chemical energy. view more (2007-07-27)
Cigarettes Harbor Many Bacteria Harmful to Human Health
Cigarettes are "widely contaminated" with bacteria, including some known to cause disease in people, concludes a new international study conducted by a University of Maryland environmental health researcher and microbial ecologists at the Ecole Centrale de Lyon in France. view more (2009-11-20)
Small, self-controlled planes combine plant pathology and engineering
A Virginia Tech plant pathologist has developed autonomous unmanned aerial vehicles (UAVs) to detect airborne pathogens above agricultural fields. view more (2007-06-14)
New insight in the fight against the Leishmania parasite
Professor Albert Descoteaux's team at Centre INRS - Institut Armand-Frappier has gained a better understanding of how the Leishmania donovani parasite manages to outsmart the human immune system and proliferate with impunity, causing visceral leishmaniasis, a chronic infection that is potentially fatal if left untreated. view more (2009-10-26)
Crossing paths in plants
On Monday 31 March ecologists will meet with molecular biologists at the University of Southampton for the most novel and broad-ranging scientific session of its kind. They will present findings in Session C5/P3 which show that the biochemical pathways which influence a plant's response to stimuli such as attack, disease or other stresses are not... view more...
