Meticillin resistant Staphylococcus aureus (MRSA) was grown in the laboratory and treated with and without manuka honey for four hours. The experiment was repeated with sugar syrup to determine if the effects seen were due to sugar content in honey alone.
The bacterial cells were then broken and the proteins isolated and separated on a system that displayed each protein as an individual spot. Many fewer proteins were seen from the manuka honey-treated MRSA cells and one particular protein, FabI, seemed to be completely missing.
FabI is a protein that is needed for fatty acid biosynthesis. This essential process supplies the bacteria with precursors for important cellular components such as lipopolysaccarides and its cell wall. The absence of these proteins in honey-treated cells could help explain the mode of action of manuka honey in killing MRSA.
"Manuka and other honeys have been known to have wound healing and anti-bacterial properties for some time," said Dr Jenkins, "But the way in which they act is still not known. If we can discover exactly how manuka honey inhibits MRSA it could be used more frequently as a first-line treatment for infections with bacteria that are resistant to many currently available antibiotics".

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,...
