The National Academies today recommended guidelines for research involving human embryonic stem cells, and urged all institutions conducting such research to establish oversight committees to ensure that the new guidelines will be followed. The guidelines are intended to enhance the integrity of privately funded human embryonic stem cell research by encouraging responsible practices, said the committee that wrote the report, a joint project between the National Academies National Research Council and Institute of Medicine.
"Heightened oversight is essential to assure the public that stem cell research is being carried out in an ethical manner," said committee co-chair Jonathan D. Moreno, Emily Davie and Joseph S. Kornfeld Professor of Biomedical Ethics and director of the Center for Biomedical Ethics at the University of Virginia, Charlottesville. "The oversight we call for will in many instances set a higher standard than required by existing laws or regulations. And while we were hesitant to recommend another bureaucratic oversight entity, the burden in this case is justified, given the novel and controversial nature of embryonic stem cell research."
"A standard set of requirements for deriving, storing, distributing, and using embryonic stem cell lines -- one to which the entire U.S. scientific community adheres -- is the best way for this research to move forward," added committee co-chair Richard O. Hynes, Daniel K. Ludwig Professor of Cancer Research and a Howard Hughes Medical Institute investigator at the Massachusetts Institute of Technology, Cambridge.

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...
