How Cost-Effective Are U.S. Cancer Prevention Services? Posted: 21 Mar 2012 05:46 AM PDT Prevention is better than cure; however, when it comes to screening for cancer new research shows that U.S. health services are not as cost-effective as international, and publically run, counterparts. The research, published in The Milbank Quarterly, compares U.S. screening services to screening in the Netherlands and found that while three to four times more screening took place in the United States, the rates of mortality were similar. read more

Berkeley Lab Researchers Show the Way Forward for Improving Organic and Molecular Electronic Devices Posted: 21 Mar 2012 05:39 AM PDT Future prospects for superior new organic electronic devices are brighter now thanks to a new study by researchers with the U.S. Department of Energy (DOE)’s Lawrence Berkeley National Laboratory (Berkeley Lab). Working at the Lab’s Molecular Foundry, a DOE nanoscience center, the team has provided the first experimental determination of the pathways by which electrical charge is transported from molecule-to-molecule in an organic thin film. Their results also show how such organic films can be chemically modified to improve conductance. read more

New hope for treating Alzheimer’s Disease: A Role for the FKBP52 protein Posted: 21 Mar 2012 05:20 AM PDT New research in humans published today reveals that the so-called FKBP52 protein may prevent the Tau protein from turning pathogenic. This may prove significant for the development of new Alzheimer’s drugs and for detecting the disease before the onset of clinical symptoms. read more

'Nanoslinky': A Novel Nanofluidic Technology for DNA Manipulation and Measurement Posted: 20 Mar 2012 09:54 PM PDT Remember Slinky®, the coiled metal spring that “walks” down stairs with just a push, momentum and gravity? Researchers at the National Institute of Standards and Technology (NIST) have developed their own version of this classic—albeit 10 million times smaller—as a novel technology for manipulating and measuring DNA molecules and other nanoscale (billionth of a meter) materials. read more

Quantum random motions can now be simulated in two dimensions, providing new insights into the behaviour of quantum objects Posted: 20 Mar 2012 09:36 PM PDT Tourists who drift aimlessly during a sightseeing tour are moving randomly - just like electrons that move from one atom to the next. To obtain a better understanding of these random motions it is often useful to reduce their complexity. Physicists do this by simulating random walks. These simulations can bring new insights in the quantum world as well. Researchers at the Max Planck Institute for the Science of Light and the University of Paderborn and their colleagues are now the first to successfully realise an arrangement for a quantum walk in two dimensions. read more

Gemcitabine with PEGPH20 breaks pancreatic tumor barrier and increased survival Posted: 20 Mar 2012 07:31 PM PDT According to a new report, pre-clinical experiments show that a combination of drugs, gemcitabine with PEGPH20, could break down the barrier surrounding pancreatic tumor, allowing chemotherapy drugs to freely spread and permeate throughout the cancerous tissue. read more

Calorie-restricted diet good or bad? Bad for the infected bowel! Posted: 20 Mar 2012 06:51 PM PDT Calorie-restricted diet good or bad? Bad for the infected bowel! Caloric restriction has long been considered to increase life span and slow the aging process. However a new study shows that calorie-restricted diet may cause more harm when infected with an inflammation-causing bacterial pathogen in the colon.  The surprising result reported by  Michigan State University researchers looked at the effects of diet on bowel disease in mice on a calorie-restricted diet.   read more

Intel Science Fair 2012 in Pittsburgh May 13-18 Posted: 20 Mar 2012 05:06 PM PDT The Intel International Science and Engineering Fair (Intel ISEF) 2012 will be held in Pittsburgh, Pennsylvania on May 13-18.  More than 1500 outstanding high school students from 65 countries are expected to present their research projects at this event. Intel ISEF is the world's largest international pre-college science competition. read more

Nuclear fusion simulation shows high-gain energy output Posted: 20 Mar 2012 02:59 PM PDT High-gain nuclear fusion could be achieved in a preheated cylindrical container immersed in strong magnetic fields, according to a series of computer simulations performed at Sandia National Laboratories. The simulations show the release of output energy that was, remarkably, many times greater than the energy fed into the container’s liner. The method appears to be 50 times more efficient than using X-rays — a previous favorite at Sandia — to drive implosions of targeted materials to create fusion conditions. read more

Study Shows Colorectal Cancer Screening Rates High in Patients with Multiple Health Problems Posted: 20 Mar 2012 12:21 PM PDT A study by University of Kentucky researchers showed that in Appalachia, colorectal cancer screening rates were higher in the population with multiple morbidities or diseases compared to those who had no morbidities at all. read more

Low-calorie diet linked to higher death rate in bowel disease model Posted: 20 Mar 2012 12:16 PM PDT In a surprising result, Michigan State University researchers looking at the effects of diet on bowel disease found that mice on a calorie-restricted diet were more likely to die after being infected with an inflammation-causing bacterial pathogen in the colon. read more

Including Ads in Mobile Apps Poses Privacy, Security Risks Posted: 20 Mar 2012 12:10 PM PDT Researchers from North Carolina State University have found that including ads in mobile applications (apps) poses privacy and security risks. In a recent study of 100,000 apps in the official Google Play market, researchers noticed that more than half contained so-called ad libraries. And 297 of the apps included aggressive ad libraries that were enabled to download and run code from remote servers – which raises significant privacy and security concerns. read more

New MIT analysis shows there’s enough room to safely store at least a century’s worth of U.S. fossil fuel emissions Posted: 20 Mar 2012 11:41 AM PDT A new study by researchers at MIT shows that there is enough capacity in deep saline aquifers in the United States to store at least a century’s worth of carbon dioxide emissions from the nation’s coal-fired powerplants. Though questions remain about the economics of systems to capture and store such gases, this study addresses a major issue that has overshadowed such proposals. read more

Pain Relievers Could be Spiking Your Blood Pressure Posted: 20 Mar 2012 11:30 AM PDT Diseases such as kidney failure and endocrine tumors are among the suspects causing high blood pressure — but could the common pain relievers in your medicine cabinet be the culprit? read more

Pesticide additives cause drifting droplets, but can be controlled Posted: 20 Mar 2012 11:23 AM PDT Chemical additives that help agricultural pesticides adhere to their targets during spraying can lead to formation of smaller "satellite" droplets that cause those pesticides to drift into unwanted areas, Purdue University researchers have found. read more

Study confirms oil from Deepwater Horizon disaster entered food chain in the Gulf of Mexico Posted: 20 Mar 2012 09:55 AM PDT Since the explosion on the BP Deepwater Horizon drilling rig in the Gulf of Mexico on April 20, 2010, scientists have been working to understand the impact that this disaster has had on the environment. For months, crude oil gushed into the water at a rate of approximately 53,000 barrels per day before the well was capped on July 15, 2010. A new study confirms that oil from the Macondo well made it into the ocean’s food chain through the tiniest of organisms, zooplankton. read more

Explosive Stars with Good Table Manners Posted: 20 Mar 2012 09:43 AM PDT An exploding star known as a Type Ia supernova plays a key role in our understanding of the universe. Studies of Type Ia supernovae led to the discovery of dark energy, which garnered the 2011 Nobel Prize in Physics. Yet the cause of this variety of exploding star remains elusive. read more

Researchers identifiy the function of a gene involved in the formation of edemas in the brain Posted: 20 Mar 2012 09:31 AM PDT The accumulation of fluids in the brain, what is known as an edema, is a common phenomenon that may be produced as a result of a knock, a heart attack or by developing a cerebral cancer. Moreover, those persons affected by a rare illness called megalencephalicleucoencephalopathy with subcortical cysts (MLC) may also suffer from oedemas. In these cases, the liquid accumulation in the brain is caused by a dysfunction of genetic origin related with the glial cells, which are responsible for maintaining the equilibrium of fluids in the brain because of the production of ion fluxes. read more

How electrons outrun vibrating nuclei – the x-ray movie Posted: 20 Mar 2012 09:20 AM PDT Researchers at the Max-Born-Institute, Berlin, Germany, resolved spatial oscillations of  electrons in a crystal by taking a real-time ‘movie’ with ultrashort x-ray flashes. Outer electrons move forth and back over the length of a chemical bond and modulate the electric properties while the tiny elongation of the inner electrons and the atomic nuclei is less than 1 % of this distance. read more
