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.

Researchers from the Institute for Quantum Computing (IQC) at the University of Waterloo led the development of a new extensible wiring technique capable of controlling superconducting quantum bits, representing a significant step towards to the realization of a scalable quantum computer.
"The quantum socket is a wiring method that uses three-dimensional wires based on spring-loaded pins to address individual qubits," said Jeremy Béjanin, a PhD...
In a paper in Scientific Reports, a research team at Worcester Polytechnic Institute describes a novel light-activated phenomenon that could become the basis for applications as diverse as microscopic robotic grippers and more efficient solar cells.
A research team at Worcester Polytechnic Institute (WPI) has developed a revolutionary, light-activated semiconductor nanocomposite material that can be used...
By forcefully embedding two silicon atoms in a diamond matrix, Sandia researchers have demonstrated for the first time on a single chip all the components needed to create a quantum bridge to link quantum computers together.
"People have already built small quantum computers," says Sandia researcher Ryan Camacho. "Maybe the first useful one won't be a single giant quantum computer...
COMPAMED has become the leading international marketplace for suppliers of medical manufacturing. The trade fair, which takes place every November and is co-located to MEDICA in Dusseldorf, has been steadily growing over the past years and shows that medical technology remains a rapidly growing market.
In 2016, the joint pavilion by the IVAM Microtechnology Network, the Product Market “High-tech for Medical Devices”, will be located in Hall 8a again and will...
'Ferroelectric' materials can switch between different states of electrical polarization in response to an external electric field. This flexibility means they show promise for many applications, for example in electronic devices and computer memory. Current ferroelectric materials are highly valued for their thermal and chemical stability and rapid electro-mechanical responses, but creating a material that is scalable down to the tiny sizes needed for technologies like silicon-based semiconductors (Si-based CMOS) has proven challenging.
Now, Hiroshi Funakubo and co-workers at the Tokyo Institute of Technology, in collaboration with researchers across Japan, have conducted experiments to...
