Constructed wetlands in planned communities can aid in surface water cleanup and flood prevention, according to Purdue University scientists who completed a five-year study on the management system.
The research, begun in 1998 on three constructed ponds, or wetland cells, on a newly renovated golf course on the university campus, showed that 11 of 17 measurable chemicals in surface water were reduced after running through the system, said Ron Turco, soil microbiologist and senior author of the report. Study results are published in the February issue of the journal Ecological Engineering. "Golf courses are a perfect place for constructed wetlands used as part of a water management system because wetlands can filter chemicals out of surface water, and they can also store excess water during storms," Turco said.
In addition, constructed wetlands act as a holding area that can provide recycled water for irrigation, a system the scientists used on the golf course, he said. "Constructed wetlands on golf courses and in planned communities are a very good water management system," Turco said. "When you build houses, roads and driveways, lots of hard surface is added, leaving no place for water to go. Building dikes and levees just moves the water problem somewhere else, causing flooding elsewhere."

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...
