Study results presented at the 13th European Cancer Conference (ECCO 13) have provided further valuable insights into certain genetic mutations which occur in childhood thyroid tumours and their link to both radiation exposure and patient age.
The unique circumstances of this study were provided for by the legacy of the radioactive accident at Chernobyl Nuclear Power Plant in April 1986. Exposure to radioactive fallout led to a large increase in the incidence of papillary thyroid cancer (PTC), which was particularly pronounced in those who were children at the time of the accident. In normal circumstances, thyroid cancer is rare in children under the age of sixteen.
The Chernobyl Tissue Bank was established in 1998 to collect biological samples from those aged under 19 at the time of the accident who subsequently developed thyroid tumours and were resident in the areas of Ukraine and Russia contaminated by the radioactive iodine (131-I) fallout. Radioactive iodine 131-1 has a short half-life of seven days and quickly dissipates in the environment. The investigators were aware of the fact that the incidence of thyroid cancer had dropped down to normal occurrence rates in those children born 9 months after the Chernobyl accident. The continued collection of material by the Tissue Bank gave the investigators a unique opportunity to compare the samples gathered from children who experienced the Chernobyl accident with those born nine months after the incident whose thyroid cancers were unlikely to arise from exposure to 131-I.

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...
