Ancient deformation of the lithosphere revealed in Eastern China


January 30th, 2015         by News -- ScienceDaily

Seismic investigations from the Qinling-Dabie-Sulu orogenic belt in eastern China suggest that this region was affected by extreme mantle perturbation and crust-mantle interaction during the Mesozoic era. The Qinling-Dabie-Sulu orogenic belt formed through the collision between the North and South China blocks, which produced large-scale destruction of the cratonic lithosphere, accompanied by widespread magmatism and metallogeny.

Computing: Common ‘data structure’ revamped to work with multicore chips


January 30th, 2015         by News -- ScienceDaily

Every undergraduate computer-science major takes a course on data structures, which describes different ways of organizing data in a computer's memory. Every data structure has its own advantages: Some are good for fast retrieval, some for efficient search, some for quick insertions and deletions, and so on. Scientists have now developed a new way of implementing priority queues that lets them keep pace with the addition of new cores. In simulations, algorithms using their data structure continued to demonstrate performance improvement with the addition of new cores, up to a total of 80 cores. Continue reading ...

DNA nanoswitches reveal how life’s molecules connect


January 30th, 2015         by News -- ScienceDaily

'Bio-molecular interaction analysis, a cornerstone of biomedical research, is traditionally accomplished using equipment that can cost hundreds of thousands of dollars,' said the senior author of a new study. 'Rather than develop a new instrument, we've created a nanoscale tool made from strands of DNA that can detect and report how molecules behave, enabling biological measurements to be made by almost anyone, using only common and inexpensive laboratory reagents.'

Scientists Use Knowledge from the Food Industry to Understand Mass Extinction


January 30th, 2015         by News -- ScienceDaily

The close of the Permian Period around 250 million years ago saw Earth's biggest extinction ever. At this time large volcanic eruptions were occurring in what is now Siberia. The volcanoes pumped out gases that led to acid rain. Falling on the supercontinent Pangaea, the acid rain killed off end-Permian forests. The demise of forests led to soil erosion and the production of organic-rich sediments in shallow marine waters. Continue reading ...

Understanding the reinforcing ability of carbon nanotubes


January 30th, 2015         by News -- ScienceDaily

A new article explores what is preventing the reinforcing ability of carbon nanotubes from being used in a ceramic matrix. Ever since their discovery, carbon nanotubes (CNTs) have been considered the ultimate additive to improve the mechanical properties of structural ceramics, such as aluminum oxide, silicon nitride and zirconium dioxide. Yet despite the remarkable strength and stiffness of CNTs, many studies have reported only marginal improvements or even the degradation of mechanical properties after these super-materials were added.
