After receiving the brunt of powerful hurricanes in 1996 and 1999, the Neuse River and Estuary and western Pamlico Sound in eastern North Carolina appear to have suffered few long-term ill effects from the storms, and have actually benefited ecologically in some ways from the storms’ scouring effects.

Those are the findings of a team of North Carolina State University scientists and collaborators from various North Carolina universities and government agencies.
Dr. JoAnn Burkholder, NC State professor of botany and director of the Center for Applied Aquatic Ecology, says the research shows that water quality, numbers and health of most of the area’s shellfish and finfish, and the overall health of the surveyed water systems – though initially acutely affected by storms, especially Hurricane Fran in 1996 – have over the long run returned to normal, suggesting the resilience of estuarine systems such as the Neuse and Pamlico Sound. Some harmful organisms that took hold before the storms are now in abeyance, suggesting the storms beneficially flushed the areas studied. The one major estuary dweller that has been slow to recover is the blue crab, the researchers say, although its numbers are now creeping back toward average abundances.

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...
