A different style of coastal barrier islands that forms under lower-energy conditions than classic ocean-facing barriers, such as North Carolinas Outer Banks, has been identified by coastal geological researchers at Duke University and the University of Ulster in Northern Ireland. The new style of islands is typically found in protected bays and lagoons.
"This is a major and important recognition," said Orrin Pilkey, a geology professor emeritus at Dukes Nicholas School of the Environment and Earth Sciences, who directs the universitys Program for the Study of Developed Shorelines. "Its a type of island quite different from the standard barrier islands on the open ocean."
"There are some people who would argue that these arent barrier islands," Pilkey said. But Pilkey, University of Ulster geology professor J. Andrew Cooper and Duke undergraduate David Lewis believe they can identify more than 20,000 uniquely "fetch-limited barrier islands" existing globally along the coastlines of every continent except Antarctica.

Researchers at the University of New Hampshire have captured a difficult-to-view singular event involving "magnetic reconnection"--the process by which sparse particles and energy around Earth collide producing a quick but mighty explosion--in the Earth's magnetotail, the magnetic environment that trails behind the planet.
Magnetic reconnection has remained a bit of a mystery to scientists. They know it exists and have documented the effects that the energy explosions can...
Biochips have been developed at TU Wien (Vienna), on which tissue can be produced and examined. This allows supplying the tissue with different substances in a very controlled way.
Cultivating human cells in the Petri dish is not a big challenge today. Producing artificial tissue, however, permeated by fine blood vessels, is a much more...
Faster and secure data communication: This is the goal of a new joint project involving physicists from the University of Würzburg. The German Federal Ministry of Education and Research funds the project with 14.8 million euro.
In our digital world data security and secure communication are becoming more and more important. Quantum communication is a promising approach to achieve...
On Saturday, 10 November 2018, the research icebreaker Polarstern will leave its homeport of Bremerhaven, bound for Cape Town, South Africa.
When choosing materials to make something, trade-offs need to be made between a host of properties, such as thickness, stiffness and weight. Depending on the application in question, finding just the right balance is the difference between success and failure
Now, a team of Penn Engineers has demonstrated a new material they call "nanocardboard," an ultrathin equivalent of corrugated paper cardboard. A square...
