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.

In just a few weeks from now, the Chinese space station Tiangong-1 will re-enter the Earth's atmosphere where it will to a large extent burn up. It is possible that some debris will reach the Earth's surface. Tiangong-1 is orbiting the Earth uncontrolled at a speed of approx. 29,000 km/h.Currently the prognosis relating to the time of impact currently lies within a window of several days. The scientists at Fraunhofer FHR have already been monitoring Tiangong-1 for a number of weeks with their TIRA system, one of the most powerful space observation radars in the world, with a view to supporting the German Space Situational Awareness Center and the ESA with their re-entry forecasts.
Following the loss of radio contact with Tiangong-1 in 2016 and due to the low orbital height, it is now inevitable that the Chinese space station will...
Fraunhofer Institute for Organic Electronics, Electron Beam and Plasma Technology FEP, provider of research and development services for OLED lighting solutions, announces the founding of the “OLED Licht Forum” and presents latest OLED design and lighting solutions during light+building, from March 18th – 23rd, 2018 in Frankfurt a.M./Germany, at booth no. F91 in Hall 4.0.

A new scenario seeking to explain how Mars' putative oceans came and went over the last 4 billion years implies that the oceans formed several hundred million...
For the first time, an interdisciplinary team from the University of Basel has succeeded in integrating artificial organelles into the cells of live zebrafish embryos. This innovative approach using artificial organelles as cellular implants offers new potential in treating a range of diseases, as the authors report in an article published in Nature Communications.
In the cells of higher organisms, organelles such as the nucleus or mitochondria perform a range of complex functions necessary for life. In the networks of...
