Provides more information than conventional x-rays or other scanning methods
Scientists at the U.S. Department of Energy’s Brookhaven National Laboratory, in collaboration with researchers at Rush Medical College, have demonstrated the effectiveness of a novel x-ray imaging technology to visualize soft tissues of the human foot that are not visible with conventional x-rays. The technique, called Diffraction Enhanced Imaging (DEI), provides all of the information imparted by conventional x-rays as well as detailed information on soft tissues previously accessible only with additional scanning methods such as ultrasound or magnetic resonance imaging (MRI). This study appears in the May 2003 issue of the Journal of Anatomy.
“We’ve previously shown that this technique can visualize tumors in breast tissue and cartilage in human knee and ankle joints, but this is the first time we have shown it to be effective at visualizing a variety of soft tissues, such as skin, cartilage, ligaments, tendons, adipose pads, and even collagen and large blood vessels,” said physicist Zhong Zhong, who works at the National Synchrotron Light Source (NSLS) at Brookhaven Lab, where the current work was done. “The ability to visualize such a range of soft tissues as well as bone and other hard tissues with just one technique has many potential applications in diagnosis,” Zhong said.

Staphylococcus aureus is a feared pathogen (MRSA, multi-resistant S. aureus) due to frequent resistances against many antibiotics, especially in hospital infections. Researchers at the Paul-Ehrlich-Institut have identified immunological processes that prevent a successful immune response directed against the pathogenic agent. The delivery of bacterial proteins with RNA adjuvant or messenger RNA (mRNA) into immune cells allows the re-direction of the immune response towards an active defense against S. aureus. This could be of significant importance for the development of an effective vaccine. PLOS Pathogens has published these research results online on 25 May 2017.
Staphylococcus aureus (S. aureus) is a bacterium that colonizes by far more than half of the skin and the mucosa of adults, usually without causing infections....

An international team of physicists has monitored the scattering behaviour of electrons in a non-conducting material in real-time. Their insights could be beneficial for radiotherapy.
We can refer to electrons in non-conducting materials as ‘sluggish’. Typically, they remain fixed in a location, deep inside an atomic composite. It is hence...
Two-dimensional magnetic structures are regarded as a promising material for new types of data storage, since the magnetic properties of individual molecular building blocks can be investigated and modified. For the first time, researchers have now produced a wafer-thin ferrimagnet, in which molecules with different magnetic centers arrange themselves on a gold surface to form a checkerboard pattern. Scientists at the Swiss Nanoscience Institute at the University of Basel and the Paul Scherrer Institute published their findings in the journal Nature Communications.
Ferrimagnets are composed of two centers which are magnetized at different strengths and point in opposing directions. Two-dimensional, quasi-flat ferrimagnets...
