Ancient deformation of the lithosphere revealed in Eastern China

Science News Daily - January 30, 2015 - 9:14pm
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.

Evidence mounts for quantum criticality theory

Science News Daily - January 30, 2015 - 9:14pm
A new study adds to the growing evidence supporting a theory that strange electronic behaviors -- including high-temperature superconductivity and heavy fermion physics -- arise from quantum fluctuations of strongly correlated electrons.

Latent HIV may lurk in 'quiet' immune cells, research suggests

Science News Daily - January 30, 2015 - 2:23pm
HIV can lie dormant in infected cells for years, even decades. Scientists think unlocking the secrets of this viral reservoir may make it possible to cure, not just treat, HIV. Researchers have gained new insight on which immune cells likely do, and do not, harbor this latent virus.

Meteorite may represent 'bulk background' of Mars' battered crust

Science News Daily - January 30, 2015 - 2:23pm
NWA 7034, a meteorite found a few years ago in the Moroccan desert, is like no other rock ever found on Earth. It's been shown to be a 4.4 billion-year-old chunk of the Martian crust, and according to a new analysis, rocks just like it may cover vast swaths of Mars.

Stress shared by same-sex couples can have unique health impacts

Science News Daily - January 30, 2015 - 1:28pm
Minority stress -- which results from being stigmatized and disadvantaged in society -- affects same-sex couples' stress levels and overall health, research indicates. Authors of a new study state that the health effects of minority stress shared by a couple can be understood as distinct from individual stress, a new framework in the field.

New method allows for greater variation in band gap tunability

Science News Daily - January 30, 2015 - 1:28pm
If you can't find the ideal material, then design a new one. By manipulating the ordered arrangement of atoms in layered complex oxide materials, scientists have found a way to control their electronic band gaps, which determines the electrical behavior of the material and how it interacts with light.

Renewable energy policies drive production of Southern wood pellets for bioenergy

Science News Daily - January 30, 2015 - 1:28pm
Policies in the European Union and elsewhere requiring the use of renewable and low greenhouse gas-emitting energy are driving demand for wood pellets used to generate bioenergy. This demand could provide new markets for US timber exports, increase wood prices, and lead to increases in forestland area.

Research uncovers connection between Craigslist personals, HIV trends

Science News Daily - January 30, 2015 - 1:28pm
Craigslist's entry into a market results in a 15.9 percent increase in reported HIV cases, according to research. When mapped at the national level, more than 6,000 HIV cases annually and treatment costs estimated between $62 million and $65.3 million can be linked to the popular website, the authors state.

Computing: Common 'data structure' revamped to work with multicore chips

Science News Daily - January 30, 2015 - 12:18pm
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.

DNA nanoswitches reveal how life's molecules connect

Science News Daily - January 30, 2015 - 12:18pm
'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.'

Ethicists question impact of hospital advertising

Science News Daily - January 30, 2015 - 12:18pm
Ethicists question the impact of health information that is available online, specifically hospital advertisements, and argue that while the Internet offers patients valuable data and tools -- including hospital quality ratings and professional treatment guidelines - that may help them when facing decisions about where to seek care or whether to undergo a medical procedure, reliable and unbiased information may be hard to identify among the growing number of medical care advertisements online.

Scientists Use Knowledge from the Food Industry to Understand Mass Extinction

Science News Daily - January 30, 2015 - 12:17pm
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.
