Researchers at MIT have devised a new method for examining how radiation damages normal tissue in the body. The knowledge may make it possible to reduce side effects for cancer patients or to develop treatments for radiation exposure.
About 50 percent of all cancer patients are treated with radiation therapy, either alone or in combination with some other type of treatment. Radiation can be very effective in killing tumor cells, but it also kills normal tissues nearby. In the gastrointestinal (GI) tract, this killing of normal cells can cause such side effects as nausea or diarrhea within days or weeks of treatment, and serious GI tissue damage can occur months or years later.
"The long-term effects that occur six months to a year or more after exposure arent reversible like the short-term ones, and they are a big unknown," said Associate Professor Jeffrey A. Coderre of MITs Department of Nuclear Science and Engineering. The damage is similar to scar tissue formation and can seriously affect tissue function in the GI tract.

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....
Physicists from the University of Würzburg are capable of generating identical looking single light particles at the push of a button. Two new studies now demonstrate the potential this method holds.

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...
