By manipulating the way bacteria "talk" to each other, researchers at Texas A&M University have achieved an unprecedented degree of control over the formation and dispersal of biofilms — a finding with potentially significant health and industrial applications, particularly to bioreactor technology. Working with E. coli bacteria, Professor Thomas K. Wood and Associate Professor Arul Jayaraman of the university's Artie McFerrin Department of Chemical Engineering have employed...

What's That Lurking In Your Bathroom Sink?

A study examining the prevalence of the fungus Fusarium in bathroom sink drains suggests that plumbing systems may be a common source of human infections. In the first extensive survey of its kind, researchers in Penn State's College of Agricultural Sciences sampled nearly 500 sink drains from 131 buildings -- businesses, homes, university dormitories and public facilities -- in Pennsylvania, Maryland, Virginia, North Carolina, South Carolina, Georgia, Florida and California. They...

Ultimate goal: Tailings water treatment plants for all oil sands operations Alberta's oilsands have water challenges. Oilsands development uses a vast amount of water and even though it's recycled multiple times, the recycling concentrates the toxins and metals leftover from extracting and upgrading the bitumen, resulting in tailings ponds that are both a lightning rod for controversy and a significant risk to the environment. A research project underway between biologists at the...

Scientists have discovered a new signal that helps invading bacteria communicate but also helps targeted rice plants coordinate defensive attacks on the disease-causing invaders, a finding that could lead to new methods of combating infection not just in plants, but in humans. Findings from the study, conducted by a team of researchers led by a University of California, Davis, scientist, will be reported in the Dec. 12 issue of the journal PLoS ONE and in the journal Discovery Medicine....

Single-celled bacteria communicate with each other using coded messages to coordinate attacks on their targets. Until now, the diversity of codes employed by these invading bacteria was thought to be extremely limited. However, a new report published Dec. 12 in PLoS ONE reveals bacterial communication by a novel, previously undescribed signal type — and, as is often the case in evolutionary stories, some plants have evolved a complementary cypher-breaking detection system that...

Research presented at ASCB annual meeting New fluorescent labeling technology that distinguishes in a single image the population size and spatial distribution of 15 different taxa has uncovered new taxon pairings that indicate unsuspected cooperation -- and standoffishness -- between members of the microbe biofilm that covers teeth, according to a presentation on Dec. 7, at the American Society for Cell Biology's Annual Meeting in Denver. Members of the genera Prevotella and...

Interfering with the ability of biofilm-forming bacteria to sense starvation increases their susceptibility to antibiotics Many infections, even those caused by antibiotic-sensitive bacteria, resist treatment. This paradox has vexed physicians for decades, and makes some infections impossible to cure. A key cause of this resistance is that bacteria become starved for nutrients during infection. Starved bacteria resist killing by nearly every type of antibiotic, even ones they have never...

Work Holds Implications for Future Bioremediation Efforts Critical genetic secrets of a bacterium that holds potential for removing toxic and radioactive waste from the environment have been revealed in a study by researchers with the U.S. Department of Energy (DOE)´s Lawrence Berkeley National Laboratory (Berkeley Lab). The researchers have provided the first ever map of the genes that determine how these bacteria interact with their surrounding environment. “Knowing how...

Pseudomonas aeruginosa is a common bacterium that can cause disease in animals and humans. It can be found in soil, water, skin flora, and most man-made environments throughout the world. It thrives in normal or hypoxic atmospheres; due to this it has colonized many natural and artificial environments. It can infect animals with damaged tissue or people with reduced immunity. Symptoms are generalized inflammation and sepsis. It can be fatal if colonization occurs in critical body organs,...

  • A somewhat riotous parade, accompanied with the blowing of tin horns, and other discordant noises; also, a burlesque serenade; a charivari.
'Callithump' is a back-formation of 'callithumpian,' a 'fanciful formation' according to the Oxford English Dictionary. However, the English Dialect Dictionary, says 'Gallithumpians' is a Dorset and Devon word from the 1790s that refers to 'a society of radical social reformers' or 'noisy disturbers of elections and meetings.'
