Cancer news articles may contribute to confusion about cancer
2010-11-11
New research from North Carolina State University shows that most online news stories about cancer contain language that likely contributes to public uncertainty about the disease – a significant finding, given that at least one-third of Americans seek health information online.
"Previous studies show that more than 100 million Americans seek health information online, and that their findings affect their health decisions," says Dr. Kami Kosenko, an assistant professor of communication at NC State and co-author of a paper describing the study. "But, while people facing ...
New highly stable fuel-cell catalyst gets strength from its nano core
2010-11-11
UPTON, NY - Stop-and-go driving can wear on your nerves, but it really does a number on the precious platinum that drives reactions in automotive fuel cells. Before large fleets of fuel-cell-powered vehicles can hit the road, scientists will have to find a way to protect the platinum, the most expensive component of fuel-cell technology, and to reduce the amount needed to make catalytically active electrodes.
Now, scientists at the U.S. Department of Energy's (DOE) Brookhaven National Laboratory have developed a new electrocatalyst that uses a single layer of platinum ...
Infant foods should be screened for mycotoxins
2010-11-11
ANTWERP – An international team of scientists calls for protecting complementary food for infants in developing countries – especially those where corn is a staple food – against fumonisin, a toxin produced by fungi. Until now, physicians thought the growth retardation of children in those regions was to be blamed on the poor nutritional value of the complementary maize porridge they receive when breast milk is no longer sufficient. But toxins indeed are involved, the scientists report in the journal Molecular Nutrition and Food Research.
The call is made by scientists ...

Dietary intervention can prevent the disease process leading to Type 1 diabetes
2010-11-11
A Finnish study confirms the hypothesis that infant feeding plays a role in the initiation of the disease process leading to type 1 diabetes in children carrying increased genetic disease risk.
The study population comprised 230 newborn infants with at least one family member affected by type 1 diabetes and a predisposing genotype based on screening cord blood at birth. The participants were randomized into two groups; the infants in the intervention group were weaned to a highly hydrolyzed casein-based formula (Nutramigen, Mead Johnson Nutrition), while those in the ...
Researchers unlock how key drug kills tropical parasites
2010-11-11
EAST LANSING, Mich. — In a major breakthrough that comes after decades of research and nearly half a billion treatments in humans, scientists have finally unlocked how a key anti-parasitic drug kills the worms brought on by the filarial diseases river blindness and elephantitis.
Understanding how the drug ivermectin works has the potential to lead to new treatments for the diseases, in which the body is infected with parasitic worms, said Charles Mackenzie, a professor of veterinary pathology in the College of Veterinary Medicine and researcher on the project. The diseases ...

Geneticist Richard Olsen and horticulturist Sue Bentz of USDA's Agricultural Research Service (ARS) teamed up with Forest Service entomologist Mike Montgomery to breed and select these tolerant hybrids. Olsen and Bentz work in the U.S. National Arboretum's Floral and Nursery Plants Research Unit in Beltsville, Md. The arboretum is located in Washington, D.C., and is operated by ARS, the principal intramural ...
By reducing disease risk, 'Desktop Medicine' will transform the practice of medicine
2010-11-11
Gone are the days when a doctor's only way of helping patients is by treating the disease after symptoms have started. Instead, a new approach to medicine, called "Desktop Medicine" is emerging, in which the emphasis shifts from diagnosing diseases and treating symptoms to identifying risk-factors for medical conditions such as hypertension and osteoporosis, and intervening before they develop. The commentary appears in the current issue of the Journal of the American Medical Association.
"Desktop medicine," a model defined by Jason Karlawish, MD, Associate Professor ...
Bowel cancer: 8 years of colonoscopy screening in Germany -- a success story
2010-11-11
By the end of this year, colonoscopy screening will have prevented bowel cancer in approximately 99 000 people since it was introduced in Germany. This is the result obtained by Hermann Brenner of the German Cancer Research Center in Heidelberg and his co-authors in their interim assessment conducted eight years after the procedure was added to the German cancer screening program. The authors present their projection and initial results of colonoscopy screening in Germany in the current edition of Deutsches Ärzteblatt International (Dtsch Arztebl Int 2010: 107(43): 753 ...
Updated NIST software uses combination testing to catch bugs fast and easy
2010-11-11
Researchers at the National Institute of Standards and Technology (NIST) have released an updated version of a computer system testing tool that can cut costs by more efficiently finding flaws. A tutorial on using the tool accompanies the new release.
Catching software "bugs" before a program is released enhances computer security because hackers often exploit these flaws to introduce malware, including viruses, to disrupt or take control of computer systems. But it's difficult. A widely cited 2002 study prepared for NIST* reported that even though 50 percent of software ...
U of M researchers find learning in the visual brain
2010-11-11
A team of researchers from the University of Minnesota's College of Liberal Arts and College of Science and Engineering have found that an early part of the brain's visual system rewires itself when people are trained to perceive patterns, and have shown for the first time that this neural learning appears to be independent of higher order conscious visual processing.
The researchers' findings could help shape training programs for people who must learn to detect subtle patterns quickly, such as doctors reading X-rays or air traffic controllers monitoring radars. In addition, ...

National Institute of Standards and Technology (NIST) researchers have developed new certified reference materials for measuring amounts of organic acids in dietary supplements formulated with Vaccinium berries—cranberries, blueberries and bilberries. As described in a recent paper,* manufacturers and researchers can use this new suite of standard reference materialsTM (SRMs) as quality assurance tools.
berry SRMs
Dietary supplement manufacturers often include health claims on products made with Vaccinium berries. Suggested benefits include prevention of urinary tract ...
Academies of science call for amendments to impracticable Genetic Diagnostics Act
2010-11-11
Many aspects of the German Genetic Diagnostics Act (Gendiagnostikgesetz) are out of touch with the latest technology, almost impossible to implement in clinical practice, or even detrimental to the success of recognised screening tests, such as newborn screening. The Act, which came into force in February 2010, is in desperate need of amendment. This was the conclusion reached by the Academy Workgroup "Predictive genetic diagnostics as an instrument of disease prevention" of the German Academy of Sciences Leopoldina, the Berlin-Brandenburg Academy of Sciences and Humanities ...
NIST pings key material in sonar, closes gap on structural mystery
2010-11-11
Using a neutron beam as a probe, researchers working at the National Institute of Standards and Technology (NIST) have begun to reveal the crystal structure of a compound essential to technologies ranging from sonar to computer memory. Their recent work* provides long-sought insight into just how a widely used material of modern technology actually works.
The compound is a "piezoelectric," a material capable of changing one kind of energy into another—mechanical to electrical, or vice versa. Long employed in sonar systems to detect sound waves, more recently piezoelectrics ...

AFM positioning: Shining light on a needle in a haystack
2010-11-11
The researchers characterize their new technique as a neat solution to the "needle in a haystack" problem of nanoscale microscopy, but it's more like the difference between finding the coffee table in a darkened room either by walking around until you fall over it, or using a flashlight. In a new paper,* a group from JILA—a joint venture of the National Institute of Standards and Technology (NIST) and the University of Colorado—finds tiny assemblies of biomolecules for subsequent detailed imaging by combining precision laser optics with atomic force microscopy.

Synapses recycle proteins for the release of neurotransmitters
2010-11-11
Neurons communicate via chemical transmitters which they store in the bubble-like synaptic vesicles and release as required. To be able to react reliably to stimulation, neurons must have a certain number of "acutely releasable" vesicles. With the help of a new method, neuroscientists at the Max Planck Institute of Experimental Medicine in Göttingen have now discovered that neurons systematically recycle the protein components necessary for transmitter release and in this way guarantee the reliability of signal transmission in the brain. If this process is disrupted, the ...
Portrait of gambling behavior in Quebec
2010-11-11
Montreal, November 10, 2010 – The initial findings of a survey on the prevalence of gambling in Quebec have been released. The study also deals with behavior problems associated with gambling. The study reveals that nearly 70 percent of Quebec adults report having bet or spent money on gambling during the previous 12 months. It also found Quebecers spend an average of $483 annually on gambling activities.
This survey was conducted between June and September 2009 throughout the province among 11,888 non-institutionalized adults over the age of 18. It constitutes the first ...
Army-funded technology detects bacteria in water
2010-11-11
November 10, 2010 -- To keep soldiers in the battlefield healthy, the U.S. Army is exploring new ways to detect harmful bacteria in water.
Current techniques for analyzing water in the field can take as long as 24 hours to complete, according to Bart Lipkens of Western New England College in Springfield, Massachusetts and his colleagues at Physical Sciences in Andover, Ma.
They are working on an alternative technology that uses sound waves to accelerate the process.
"The goal of our project is to speed up the detection of bacteria in water supplies," said Lipkens. ...
Evolutionary bestseller in image processing
2010-11-11
The eye is not just a lens that takes pictures and converts them into electrical signals. As with all vertebrates, nerve cells in the human eye separate an image into different image channels once it has been projected onto the retina. This pre-sorted information is then transmitted to the brain as parallel image sequences. Scientists from the Max Planck Institute of Neurobiology in Martinsried have now discovered that fruit flies process optical information in a similar way. The evidence suggests that this type of wiring is an effective energy-saving mechanism and is therefore ...
Out-sniffing bomb-sniffing dogs
2010-11-11
Dogs have long been called man's best bomb detector –– until now.
A Tel Aviv University scientist leads a research team that has developed a powerful electronic sensor to detect multiple kinds of explosives –– including those used in the recent Yemeni bomb threat. Based on nanotechnology advances, the new sensor is small, portable, and is more sensitive and reliable at detecting explosives than any sniffer dog, says its lead researcher Prof. Fernando Patolsky of Tel Aviv University's Raymond and Beverly Sackler School of Chemistry.
With scientific findings on it published ...
GM, Chrysler bankruptcies created troubling legacy, legal scholars say
2010-11-11
CHAMPAIGN, Ill. — The Chrysler and General Motors bankruptcy reorganizations represented a sea change in corporate restructuring, one that could portend the end of our current system of bankruptcy reorganization, according to a published article by two University of Illinois experts in bankruptcy law.
Law professors Charles J. Tabb and Ralph Brubaker argue that the legal principles applied in the GM and Chrysler bankruptcies – two of the largest in U.S. history at $83.5 and $39.9 billion, respectively – were misguided, and ultimately have undermined the distributional ...
'Toxic toy crisis' requires fresh solutions
2010-11-11
Manufacturer recalls of toys, promotional drinking glasses, and other children's products constitute an ongoing "toxic toys crisis" that requires banning potentially harmful ingredients in these products and other changes in policy and practices. That's the conclusion of a new analysis in ACS' Environmental Science & Technology, a semi-monthly journal.
Monica Becker, Sally Edwards and Rachel Massey note that in June the United States government recalled 12 million promotional drinking glasses sold at a fast-food restaurant chain because the painted coating contained ...
Seeing the invisible: New CSI tool visualizes bloodstains and other substances
2010-11-11
Snap an image of friends in front of a window curtain and the camera captures the people - and invisible blood stains splattered on the curtain during a murder. Sound unlikely? Chemists from the University of South Carolina are reporting development of a camera with that ability to see the invisible, and more. Called multimode imaging in the thermal infrared, the new technology could find uses in crime scene investigations and elsewhere, they say in a series of three reports in ACS' Analytical Chemistry, a semi-monthly journal.

DNA repair protein caught in act of molecular theft
2010-11-11
Scientists have observed, for the first time, an intermediate stage in the chemical process that repairs DNA methylation damage and regulates many important biological functions that impact health conditions such as obesity, cancer and diabetes.
The observations focused on the bacterial DNA repair protein AlkB, but the results also apply to several proteins in the same family that play key regulatory roles in humans. Armed with these results, researchers may one day develop methods for blocking the protein's efforts to perform the biologically important demethylation ...
