Sandwiching individual graphene sheets between insulating layers in order to produce electrical devices with unique new properties, the method could open up a new dimension of physics research. Writing in Nature Materials, the scientists show that a new side-view imaging technique can be used to visualize the individual atomic layers of graphene within the devices they have built. They found that the structures were almost perfect even when more than 10 different layers were used to build the stack. This surprising result indicates that the latest techniques of isolating ...

BOSTON, MA—A research team led by Xian Chang Li, MD, PhD, Brigham and Women's Hospital (BWH) Transplantation Research Center, has shed light on how a population of lymphocytes, called CD4+ T cells, mature into various subsets of adult T helper cells. In particular, the team uncovered that a particular cell surface molecule, known as OX40, is a powerful inducer of new T helper cells that make copious amounts of interleukin-9 (IL-9) (and therefore called TH9 cells) in vitro; such TH9 cells are responsible for ongoing inflammation in the airways in the lungs in vivo. The ...

BOSTON (July 29, 2012) – Researchers from the Massachusetts Eye and Ear Infirmary, The Children's Hospital of Philadelphia, Loyola University Chicago Health Sciences Division and their collaborators have isolated an elusive human gene that causes a common form of Leber congenital amaurosis (LCA), a relatively rare but devastating form of early-onset blindness. The new LCA gene is called NMNAT1. Finding the specific gene mutated in patients with LCA is the first step towards developing sight-saving gene therapy. LCA is an inherited retinal degenerative disease characterized ...

A team of British and Australian scientists has discovered an important method of how carbon is drawn down from the surface of the Southern Ocean to the deep waters beneath. The Southern Ocean is an important carbon sink in the world – around 40% of the annual global CO2 emissions absorbed by the world's oceans enter through this region. Reporting this week in the journal Nature Geoscience, scientists from British Antarctic Survey (BAS) and Australia's national research agency, the Commonwealth Scientific and Industrial Research Organisation (CSIRO), reveal that rather ...

DURHAM, N.C. – Alternating hemiplegia of childhood (AHC) is a very rare disorder that causes paralysis that freezes one side of the body and then the other in devastating bouts that arise at unpredictable intervals. Seizures, learning disabilities and difficulty walking are common among patients with this diagnosis. Researchers at Duke University Medical Center have now discovered that mutations in one gene cause the disease in the majority of patients with a diagnosis of AHC, and because of the root problem they discovered, a treatment may become possible. The study ...

"We see landslides everywhere in the solar system," says Kelsi Singer, graduate student in earth and planetary sciences in Arts & Sciences at Washington University in St. Louis, "but Saturn's icy moon Iapetus has more giant landslides than any body other than Mars." The reason, says William McKinnon, PhD, professor of earth and planetary sciences, is Iapetus' spectacular topography. "Not only is the moon out-of-round, but the giant impact basins are very deep, and there's this great mountain ridge that's 20 kilometers (12 miles) high, far higher than Mount Everest. "So ...

On a time scale of tens to hundreds of millions of years, the geomagnetic field may be influenced by currents in the mantle. The frequent polarity reversals of Earth's magnetic field can also be connected with processes in the mantle. These are the research results presented by a group of geoscientists in the new advance edition of "Nature Geoscience" on Sunday, July 29th. The results show how the rapid processes in the outer core, which flows at rates of up to about one millimeter per second, are coupled with the processes in the mantle, which occur more in the velocity ...

July 29th, 2012, Shenzhen, China – A five-country international team, led by Casey Eye Institute Molecular Diagnostic laboratory, BGI and Zhejiang University School of Medicine First Affiliated Hospital identified the NMNAT1 mutations as a cause of Leber congenital amaurosis (LCA), one of the most common causes of inherited blindness in children. The latest study was published online in Nature Genetics, reporting the genetic characteristics underlying some LCA patients, and providing important evidences that support NMNAT1 as a promising target for the gene therapy of LCA. LCA ...

CORVALLIS, Ore. – The chronic drought that hit western North America from 2000 to 2004 left dying forests and depleted river basins in its wake and was the strongest in 800 years, scientists have concluded, but they say those conditions will become the "new normal" for most of the coming century. Such climatic extremes have increased as a result of global warming, a group of 10 researchers reported today in Nature Geoscience. And as bad as conditions were during the 2000-04 drought, they may eventually be seen as the good old days. Climate models and precipitation projections ...

TORONTO, ON – Researchers from the University of Toronto (U of T) and King Abdullah University of Science & Technology (KAUST) have made a breakthrough in the development of colloidal quantum dot (CQD) films, leading to the most efficient CQD solar cell ever. Their work is featured in a letter published in Nature Nanotechnology. The researchers, led by U of T Engineering Professor Ted Sargent, created a solar cell out of inexpensive materials that was certified at a world-record 7.0% efficiency. "Previously, quantum dot solar cells have been limited by the large internal ...

After the fall of the Soviet Union twenty years ago, water distribution in Central Asia became a source of conflict. In areas where summer precipitation is low, glaciers play an important role when considering the quantity of available water. The Tien Shan region is a prime example; mountain glaciers in this region contribute significantly to the fresh water supply in the arid zones of Kyrgyzstan, Kazakhstan, Uzbekistan, Turkmenistan, and Northwestern China. Like Switzerland, Kyrgyzstan serves as a water tower for its neighboring countries. While the impact of climate ...

SALT LAKE CITY, July 30, 2012 – In the years after Columbus' voyage, burning of New World forests and fields diminished significantly – a phenomenon some have attributed to decimation of native populations by European diseases. But a new University of Utah-led study suggests global cooling resulted in fewer fires because both preceded Columbus in many regions worldwide. "The drop in fire [after about A.D. 1500] has been linked previously to the population collapse. We're saying no, there is enough independent evidence that the drop in fire was caused by cooling climate," ...

HAMILTON, ON (July 30, 2012) – Child abuse experts say psychological abuse can be as damaging to a young child's physical, mental and emotional health as a slap, punch or kick. While difficult to pinpoint, it may be the most challenging and prevalent form of child abuse and neglect, experts say in an American Academy of Pediatrics (AAP) position statement on psychological maltreatment in the August issue of the journal Pediatrics. Psychological abuse includes acts such as belittling, denigrating, terrorizing, exploiting, emotional unresponsiveness, or corrupting a child ...

A new analysis has found that doing away with PSA (prostate specific antigen) testing for prostate cancer would likely cause three times as many men to develop advanced disease that has spread to other parts of the body before being diagnosed. Published early online in CANCER, a peer-reviewed journal of the American Cancer Society, the study suggests that PSA testing and early detection may prevent approximately 17,000 men each year from having such advanced prostate cancer at diagnosis. PSA testing has come under fire recently as a potentially ineffective screen for ...

Eliminating the PSA test to screen for prostate cancer would be taking a big step backwards and would likely result in rising numbers of men with metastatic cancer at the time of diagnosis, predicted a University of Rochester Medical Center analysis published in the journal, Cancer. The URMC study suggests that the prostate-specific antigen (PSA) test and early detection may prevent up to 17,000 cases of metastatic prostate cancer a year. Data shows, in fact, that if age-specific pre-PSA era incidence rates were to occur in the present day, the number of men whose cancer ...

Chicago—(July 30, 2012): A surgical patient safety program that combines three components—accurate outcome measurement, support of hospital leadership, and engaged frontline providers—reduces surgical site infections (SSIs) by 33 percent in patients who undergo colorectal procedures, according to a new study published in the August issue of the Journal of the American College of Surgeons. SSIs are the most common complication for this high-risk population, occurring in 15 to 30 percent of patients after colorectal operations, according to the study authors. "Colorectal ...

In a recently released draft of a bill that may be proposed as early as the U.S. Senate's next term, Senators Jeff Bingaman(D-NM) and Olympia Snowe (R-ME) are working on what appear to be aggressive improvements to the Energy Policy Act of 2005, which provides tax benefits for the installation of energy efficient commercial building improvements. The Act is also known as EPACT or 179D. Currently, EPACT allows a tax deduction of up to $1.80 per sq. foot under section 179D of the tax code for commercial buildings with energy efficient installations and upgrades to HVAC, ...

This leg-pulling tale tells of a group of mis-guided, if slightly loony, scientists, of a lovely woman, a handsome athlete and  of two mischievous Greek gods who spill the beans on a scheme to privatize the USA and reduce the deficit by selling off the Western states.  So, what's the price of real estate in the fifth dimension? Born on the banks of the Detroit River in an orange crate house next to a pot-belly stove in the cold spring of 1930, Guerrino Amati worked his way through a BA English from Wayne State University and, later, after a stint in the US Army, an MA ...
