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.

Novel highly efficient and brilliant gamma-ray source: Based on model calculations, physicists of the Max PIanck Institute for Nuclear Physics in Heidelberg propose a novel method for an efficient high-brilliance gamma-ray source. A giant collimated gamma-ray pulse is generated from the interaction of a dense ultra-relativistic electron beam with a thin solid conductor. Energetic gamma-rays are copiously produced as the electron beam splits into filaments while propagating across the conductor. The resulting gamma-ray energy and flux enable novel experiments in nuclear and fundamental physics.

Stable joint cartilage can be produced from adult stem cells originating from bone marrow. This is made possible by inducing specific molecular processes occurring during embryonic cartilage formation, as researchers from the University and University Hospital of Basel report in the scientific journal PNAS.
Certain mesenchymal stem/stromal cells from the bone marrow of adults are considered extremely promising for skeletal tissue regeneration. These adult stem...
