Researchers from Midwestern University in Illinois, Curtin University of Technology in Australia, and Illinois State University have found that when bacteria become resistant to pine oil cleaners (POC), a common household disinfectant, they may also be resistant to some antibiotics. Their findings appear in the November 2002 issue of Applied and Environmental Microbiology.
In the study, POC-resistant Staphylococcus aureus were found to also be resistant to the antibiotics, vancomycin and oxacillin. Further testing suggests that the same genetic mechanism may be responsible for both types of resistance.
"These results add to a growing body of reports suggesting that common disinfectants can select for bacteria with reduced susceptibilities to antibiotics," say the researchers.

The Fraunhofer Institute for Laser Technology ILT has developed an inline system for testing, qualifying and adjusting the focused powder jet of the nozzles of laser metal deposition machines. With this system, nozzles can be certified and the caustic characterized completely. The user can also visualize and monitor the process thanks to the camera module with integrated illumination.
Laser Material Deposition has already proven itself in various areas – for example when repairing tools or applying anti-corrosion coatings. But the result...
Scientists at the Max Planck Institute (MPI) for Polymer Research have developed the novel 2D TIRV spectroscopy technique to observe coupling between intramolecular and intermolecular vibrations that make water molecules “dance”.
Liquid water is permeated by a highly dynamic network of strong hydrogen bonds. Motions of molecules in this network underlie fundamental physical and chemical...
An Innsbruck team of experimental physicists, in collaboration with theorists from Innsbruck and Hannover, has for the first time observed so-called roton quasiparticles in a quantum gas. Empirically introduced by Landau to explain the bizarre properties of superfluid liquid Helium, these quasiparticles reflect an "energy softening" in the system as precursor of a crystallization instability. The new work published in Nature Physics demonstrate similar phenomena in the quantum-gas phase thanks to magnetic interactions, paving the way for a novel understanding of paradigmatic states of quantum fluids, such as supersolids.
Discovered in liquid helium about 80 years ago, superfluidity is a counterintuitive phenomenon, in which quantum physics and particle-wave duality manifest at...

Researchers have developed an imaging technique that uses a tiny, super sharp needle to nudge a single nanoparticle into different orientations and capture 2-D images to help reconstruct a 3-D picture. The method demonstrates imaging of individual nanoparticles at different orientations while in a laser-induced excited state.
The findings, published in The Journal of Chemical Physics, brought together researchers from the University of Illinois and the University of Washington,...
