Coiled baskets made from sweetgrass have been an important source of income for the Gullah community around Charleston, South Carolina for over a century. Descendants of West Africans brought in as slaves, Gullah artisans now find a comfortable livelihood threatened by dwindling supplies of the native grass they have long used to make baskets.
In 2002, the USDA Forest Service Southern Research Station (SRS) and the College of Charleston, with funding from the South Carolina Sea Grant Consortium, set up a study designed to involve basket makers in finding solutions for the scarcity of the native coastal plant. The findings are covered in a recent article in the journal Economic Botany.
Marianne Burke (research ecologist with the SRS unit in Charleston), Angela Halfacre (associate professor of political science, College of Charleston), and Zachary Hart (at the time of the study a student at the College of Charleston, now working for the Trust for Public Land) interviewed 23 Gullah basket makers between June 2002 and January 2003. Tapes of the interviews were transcribed and then analyzed to identify common views and practices to inform a long-term management plan for sweetgrass. “This is an environmental issue that directly affects local Gullah people and could impact one of the oldest traditional art forms practiced in the lowcountry,” says Burke. “The situation offers a great opportunity to learn more about involving the public in making decisions about managing natural resources.”

The operational speed of semiconductors in various electronic and optoelectronic devices is limited to several gigahertz (a billion oscillations per second). This constrains the upper limit of the operational speed of computing. Now researchers from the Max Planck Institute for the Structure and Dynamics of Matter in Hamburg, Germany, and the Indian Institute of Technology in Bombay have explained how these processes can be sped up through the use of light waves and defected solid materials.
Light waves perform several hundred trillion oscillations per second. Hence, it is natural to envision employing light oscillations to drive the electronic...
Most natural and artificial surfaces are rough: metals and even glasses that appear smooth to the naked eye can look like jagged mountain ranges under the microscope. There is currently no uniform theory about the origin of this roughness despite it being observed on all scales, from the atomic to the tectonic. Scientists suspect that the rough surface is formed by irreversible plastic deformation that occurs in many processes of mechanical machining of components such as milling.
Prof. Dr. Lars Pastewka from the Simulation group at the Department of Microsystems Engineering at the University of Freiburg and his team have simulated such...

Researchers at Chalmers University of Technology, Sweden, recently completed a 5-year research project looking at how to make fibre optic communications systems more energy efficient. Among their proposals are smart, error-correcting data chip circuits, which they refined to be 10 times less energy consumptive. The project has yielded several scientific articles, in publications including Nature Communications.
Streaming films and music, scrolling through social media, and using cloud-based storage services are everyday activities now.
After helping develop a new approach for organic synthesis -- carbon-hydrogen functionalization -- scientists at Emory University are now showing how this approach may apply to drug discovery. Nature Catalysis published their most recent work -- a streamlined process for making a three-dimensional scaffold of keen interest to the pharmaceutical industry.
"Our tools open up whole new chemical space for potential drug targets," says Huw Davies, Emory professor of organic chemistry and senior author of the paper.
