Water quality in the Rio Chone estuary in Ecuador has degraded over the last three decades by a combination of man-made impacts, including the input of organic wastes from shrimp farming activities located in what were once tropical mangrove forests.
An article in the current issue of the Journal of Coastal Research describes water quality experiments by University of Rhode Island oceanographers Diana Stram and Chris Kincaid and US Environmental Protection Agency (EPA) oceanographer Dan Campbell to assess the extent of water quality degradation in this ecologically sensitive area. The project was funded by a URI/EPA cooperative fellowship agreement and by the URI Coastal Resources Center.
The Rio Chone estuary has a history of water quality problems due to the combination of seasonal climate influences and management of natural resources. The estuary is affected primarily by an influx of sediment because of erosion of hillsides and construction of ponds; seasonal climate changes combined with decreased freshwater flow; and shrimp mariculture development resulting in mangrove habitat loss and the flushing of shrimp pond production wastes into the estuary.

The world's highest gain high power laser amplifier - by many orders of magnitude - has been developed in research led at the University of Strathclyde.
The researchers demonstrated the feasibility of using plasma to amplify short laser pulses of picojoule-level energy up to 100 millijoules, which is a 'gain'...
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.
The quantum computer has fuelled the imagination of scientists for decades: It is based on fundamentally different phenomena than a conventional computer....
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...
