Doctors have become increasingly concerned by the problem of “super-bugs”—bacteria that have become resistant to standard antibiotics. It is well known that a high rate of antibiotic prescribing in hospitals contributes to the emergence of drug resistant bacteria. But for some antibiotics, an even more important factor contributing to such emergence, argues a team of researchers in the open access international medical journal PLoS Medicine, is the use of antibiotics in agriculture.
“Evidence suggests that antibiotic use in agriculture has contributed to antibiotic resistance in the pathogenic bacteria of humans,” say David Smith of the Fogarty International Center, Jonathan Dushoff of Princeton University and the Fogarty International Center, and J.Glenn Morris Jr. of the University of Maryland.
Antibiotics and antibiotic resistant bacteria are found in the air and soil around farms, in surface and ground water, in wild animal populations, and on retail meat and poultry. These resistant bacteria are carried into the kitchen on contaminated meat and poultry where other foods are cross-contaminated because of common, unsafe handling practices. Following ingestion, bacteria occasionally survive the formidable but imperfect gastric barrier to colonize the gut—which in turn may transmit the resistant bacteria to humans.

The formation of stars in distant galaxies is still largely unexplored. For the first time, astron-omers at the University of Geneva have now been able to closely observe a star system six billion light-years away. In doing so, they are confirming earlier simulations made by the University of Zurich. One special effect is made possible by the multiple reflections of images that run through the cosmos like a snake.
Today, astronomers have a pretty accurate idea of how stars were formed in the recent cosmic past. But do these laws also apply to older galaxies? For around a...
Just because someone is smart and well-motivated doesn't mean he or she can learn the visual skills needed to excel at tasks like matching fingerprints, interpreting medical X-rays, keeping track of aircraft on radar displays or forensic face matching.
That is the implication of a new study which shows for the first time that there is a broad range of differences in people's visual ability and that these...
Computer Tomography (CT) is a standard procedure in hospitals, but so far, the technology has not been suitable for imaging extremely small objects. In PNAS, a team from the Technical University of Munich (TUM) describes a Nano-CT device that creates three-dimensional x-ray images at resolutions up to 100 nanometers. The first test application: Together with colleagues from the University of Kassel and Helmholtz-Zentrum Geesthacht the researchers analyzed the locomotory system of a velvet worm.
During a CT analysis, the object under investigation is x-rayed and a detector measures the respective amount of radiation absorbed from various angles....
The quantum world is fragile; error correction codes are needed to protect the information stored in a quantum object from the deteriorating effects of noise. Quantum physicists in Innsbruck have developed a protocol to pass quantum information between differently encoded building blocks of a future quantum computer, such as processors and memories. Scientists may use this protocol in the future to build a data bus for quantum computers. The researchers have published their work in the journal Nature Communications.
Future quantum computers will be able to solve problems where conventional computers fail today. We are still far away from any large-scale implementation,...
