A microbiological survey of households finds little significant difference in levels of bacteria or antibiotic resistance between those that use antibacterial cleaning products and those who do not. Researchers from Tufts University School of Medicine report their findings today at the 103rd General Meeting of the American Society for Microbiology.
"The use of biocides, also called antibacterials, has become increasingly popular for regular household use. While originally developed to control transmission of infectious disease agents among sick patients, these same products are increasingly incorporated into domestic household cleaners, healthcare products, clothes, and plastics," says Bonnie Marshall, one of the study researchers.
In contrast to alcohols, peroxides and bleach, which quickly dissipate from environmental surfaces, common antibacterial chemicals such as triclosan and quaternary ammonium compounds leave residues which can exert a more prolonged effect on the microbiology of the application site. Given that triclosan-resistant mutants of E. coli and Staphylococcus aureus have been isolated in the laboratory, concern has developed over the effect of home usage of residue-producing biocides on the microbiology of the home. Of particular interest is the possibility that prolonged application may promote higher levels of antibiotic resistance in the normal and/or disease-causing bacteria.

A new manufacturing technique uses a process similar to newspaper printing to form smoother and more flexible metals for making ultrafast electronic devices.
The low-cost process, developed by Purdue University researchers, combines tools already used in industry for manufacturing metals on a large scale, but uses...
For the first time ever, scientists have determined the cosmic origin of highest-energy neutrinos. A research group led by IceCube scientist Elisa Resconi, spokesperson of the Collaborative Research Center SFB1258 at the Technical University of Munich (TUM), provides an important piece of evidence that the particles detected by the IceCube neutrino telescope at the South Pole originate from a galaxy four billion light-years away from Earth.
To rule out other origins with certainty, the team led by neutrino physicist Elisa Resconi from the Technical University of Munich and multi-wavelength...
For the first time a team of researchers have discovered two different phases of magnetic skyrmions in a single material. Physicists of the Technical Universities of Munich and Dresden and the University of Cologne can now better study and understand the properties of these magnetic structures, which are important for both basic research and applications.
Whirlpools are an everyday experience in a bath tub: When the water is drained a circular vortex is formed. Typically, such whirls are rather stable. Similar...
Physicists working with Roland Wester at the University of Innsbruck have investigated if and how chemical reactions can be influenced by targeted vibrational excitation of the reactants. They were able to demonstrate that excitation with a laser beam does not affect the efficiency of a chemical exchange reaction and that the excited molecular group acts only as a spectator in the reaction.
A frequently used reaction in organic chemistry is nucleophilic substitution. It plays, for example, an important role in in the synthesis of new chemical...
Optical spectroscopy allows investigating the energy structure and dynamic properties of complex quantum systems. Researchers from the University of Würzburg present two new approaches of coherent two-dimensional spectroscopy.
"Put an excitation into the system and observe how it evolves." According to physicist Professor Tobias Brixner, this is the credo of optical spectroscopy....
