New GSA Today science investigates lithosphere of the Central Iranian plateau
2015-07-13
(Press-News.org) Boulder, Colorado, USA - In the July issue of GSA Today, Franz Neubauer of the University of Salzburg and Fariba Kargaranbafghi of the University of Yazd describe thinning of the lithosphere that they associate with the formation of a metamorphic core complex in the Central Iranian plateau.
The core complex is located within a continental rift and was exhumed at a rate of approx. 0.75 to 1.3 km per million years during the main phase of oceanic subduction of the Arabian plate beneath the Central Iranian block between ca. 30 and 49 million years ago.
The authors indicate that lithosphere and continental crust were thinned beneath regions of surface extension. The thinning of the underlying lithosphere appears to have been compensated by hot asthenosphere, as indicated by low seismic velocities in the Central Iranian block. The authors conclude that the development of the core complex involved lithospheric removal associated with extension and upwelling of hot asthenosphere. Later processes, like slab break-off and associated uplift of the Central Iranian plateau, may have modified the structure.

A newborn's first stool can signal the child may struggle with persistent cognitive problems, according to Case Western Reserve University Project Newborn researchers.
In particular, high levels of fatty acid ethyl esters (FAEE) found in the meconium (a newborn's first stool) from a mother's alcohol use during pregnancy can alert doctors that a child is at risk for problems with intelligence and reasoning.
Left untreated, such problems persist into the teen years, the research team from the Jack, Joseph and Morton Mandel School of Applied Social Sciences found.

Rice University engineers have demonstrated the first system that allows wireless data transmissions over UHF channels during active TV broadcasts. If the technology were incorporated into next-generation TVs or smart remotes, it could significantly expand the reach of so-called "super Wi-Fi" networks in urban areas.
"Due to the popularity of cable, satellite and Internet TV, the UHF spectrum is one of the most underutilized portions of the wireless spectrum in the United States," said lead researcher Edward Knightly. "That's a bitter irony because the demand for mobile ...

(PHILADELPHIA) - Cancer is a disease of cell growth, but most tumors only become lethal once they metastasize or spread from their first location to sites throughout the body. For the first time, researchers at Thomas Jefferson University in Philadelphia report a single molecule that appears to be the central regulator driving metastasis in prostate cancer. The study, published online July 13th in Cancer Cell, offers a target for the development of a drug that could prevent metastasis in prostate cancer, and possibly other cancers as well.

Foraging and eating wild mushrooms can result in liver failure and even death because mistaking toxic mushrooms for edible varieties is common, illustrates a case published in CMAJ (Canadian Medical Association Journal)
"Distinguishing safe from harmful mushrooms is a challenge even for mycologists," writes Dr. Adina Weinerman, Division of General Internal Medicine, Sunnybrook Health Sciences Centre, Toronto, Ontario, with coauthors.
The case focuses on a previously healthy 52-year-old immigrant woman of Asian descent who had foraged for wild mushrooms in a local park ...

Combining chemotherapy with new drugs that target a protein that helps cancer cells to withstand chemotherapy could drastically improve treatment, according to research published in Cancer Cell.
Researchers at the University of Manchester carefully studied a network of proteins that kick into action when cancer cells in the lab are treated with a class of chemotherapy drugs called taxanes*. These drugs are commonly used to treat several cancers - including breast, ovarian and prostate cancers. But not all cancers respond to them, and it's difficult to predict which patients ...

Baltimore, Md., July 13, 2015 - A new study by researchers at University of Maryland School of Medicine has identified promising compounds that could successfully treat depression in less than 24 hours while minimizing side effects. Although they have not yet been tested in people, the compounds could offer significant advantages over current antidepressant medications.
The research, led by Scott Thompson, PhD, Professor and Chair of the Department of Physiology at the University of Maryland School of Medicine (UM SOM), was published this month in the journal Neuropsychopharmacology.

Using molds to shape things is as old as humanity. In the Bronze Age, the copper-tin alloy was melted and cast into weapons in ceramic molds. Today, injection and extrusion molding shape hot liquids into everything from car parts to toys.
For this to work, the mold needs to be stable while the hot liquid material hardens into shape. In a breakthrough for nanoscience, Cornell polymer engineers have made such a mold for nanostructures that can shape liquid silicon out of an organic polymer material. This paves the way for perfect, 3-D, single crystal nanostructures.

From the smell of flowers to the taste of wine, our perception is strongly influenced by prior knowledge and expectations, a cognitive process known as top-down control.
In a University of California, San Diego School of Medicine study published July 13 in the online journal Nature Neuroscience, a research team led by Takaki Komiyama, PhD, assistant professor of neurosciences and neurobiology, reports that in mouse models, the brain significantly changed its visual cortex operation modes by implementing top-down processes during learning.
"We found that when the mouse ...

LOS ANGELES (July 13, 2015) - Research for Her™, Cedars-Sinai's groundbreaking online registry that matches women with research studies and clinical trials, enrolled study participants more quickly when compared with traditional paper-based registries, according to new research published in the journal Gynecologic Oncology.
Historically, fewer women have participated in clinical research and only 3 to 5 percent of patients nationally enroll in trials.
"Research for Her is committed to changing these statistics and improving patient lives," said B.J. Rimel, ...

Spending more leisure time sitting was associated with a higher risk of total cancer risk in women, and specifically with multiple myeloma, breast, and ovarian cancers, according a new study. The higher risk was present even after taking into account BMI, physical activity, and other factors. The study, appearing in Cancer Epidemiology, Biomarkers, and Prevention, found no association between sitting time and cancer risk in men.
While extensive research links physical activity to cancer prevention, few studies have examined the link between sitting time and the risk of ...
