Insecticides from genetically modified corn present in adjacent streams
2010-09-28
In a paper published this week in the Proceedings of the National Academy of Sciences, Cary Institute aquatic ecologist Dr. Emma Rosi-Marshall and colleagues report that streams throughout the Midwestern Corn Belt are receiving insecticidal proteins that originate from adjacent genetically modified crops. The protein enters streams through runoff and when corn leaves, stalks, and plant parts are washed into stream channels.
Genetically-modified plants are a mainstay of large-scale agriculture in the American Midwest, where corn is a dominant crop. In 2009, more than ...

Rewiring a damaged brain
2010-09-28
Researchers in the Midwest are developing microelectronic circuitry to guide the growth of axons in a brain damaged by an exploding bomb, car crash or stroke. The goal is to rewire the brain connectivity and bypass the region damaged by trauma, in order to restore normal behavior and movement.
Pedram Mohseni, a professor of electrical engineering and computer science at Case Western Reserve University, and Randolph J. Nudo, a professor of molecular and integrative physiology at Kansas University Medical Center, believe repeated communications between distant neurons in ...
Baby boomers raise midlife suicide rate
2010-09-28
Baby boomers appear to be driving a dramatic rise in suicide rates among middle-aged people, a new study finds.
The suicide rate for middle-aged people – a group considered relatively protected from suicide and with historically stable suicide rates – took an upward jump between 1999 and 2005, according to research by sociologists Ellen Idler of Emory University and Julie Phillips of Rutgers University.
Their study has been published in the September/October issue of the journal Public Health Reports.
"The findings are disturbing, because they're a reversal of a long-standing ...
GMO research: Report on concrete measures to avoid mixing of GM and conventional maize
2010-09-28
A report presented today by Health and Consumer Policy Commissioner John Dalli to the Agriculture Council concludes that specific measures relating to storing and the application of isolation distances can help limit or avoid the co-mingling of genetically modified (GM) maize with conventional and organic maize. In particular, the Best Practice Document, prepared by the European Coexistence Bureau (ECoB) and published by the European Commission's Joint Research Centre (JRC), notes that storing seeds adequately and applying spatial isolation are the best ways to limit or ...
Homeless youths most often victims of crime: study led by York U researcher
2010-09-28
TORONTO, Sept. 27, 2010 − Homeless young people are victims of crime at rates that society would consider unacceptable for any other group, according to a new report by researchers at York University and the University of Guelph.
The report, Surviving Crime and Violence: Street Youth and Victimization in Toronto, highlights the degree to which it is street youth themselves − often perceived as delinquent and dangerous − who are vulnerable to crime and violence.
"The very people we are taught to fear are the ones who are most at risk," said Professor ...
Study finds brainstorming 'rules' can lead to real-world success in business settings
2010-09-28
Researchers have long held that there are steps that can be taken to make brainstorming sessions more productive. New research from North Carolina State University finds that these recommendations actually do contribute to success when applied in real-world business environments.
"Previous research has laid out best practices that are conducive to brainstorming, or group decision making, and we wanted to see whether using those practices makes a difference in the real world," says Dr. Joe Brazel, associate professor of accounting at NC State and co-author of a paper describing ...
Interaction with neighbors: Neuronal field simulates brain activity
2010-09-28
The appearance of a spot of light on the retina causes sudden activation of millions of neurons in the brain within tenths of milliseconds. At the first cortical processing stage, the primary visual cortex, each neuron thereby receives thousands of inputs from both close neighbors and further distant neurons, and also sends-out an equal amount of output to others.
During the recent decades, individual characteristics of these widespread network connections and the specific transfer characteristics of single neurons have been widely derived. However, a coherent population ...
Rapid test to save Indian vultures from extinction
2010-09-28
Diclofenac, an anti-inflammatory agent, has been deployed successfully in human medicine for decades. In most EU countries medication containing Diclofenac is only approved for treatment of humans. In India, Pakistan and Nepal it has been deployed in veterinary medicine as well since the 90s, in particular for livestock. When vultures feed on cattle carcasses, they too ingest the drug. As a result, the populations of three species of these birds of prey – the Indian vulture, the Oriental white-backed vulture and the slender-billed vulture – have shrunk to a mere three percent ...
Quarks 'swing' to the tones of random numbers
2010-09-28
At the Large Hadron Collider at CERN protons crash into each other at incredibly high energies in order to 'smash' the protons and to study the elementary particles of nature – including quarks. Quarks are found in each proton and are bound together by forces which cause all other known forces of nature to fade. To understand the effects of these strong forces between the quarks is one of the greatest challenges in modern particle physics. New theoretical results from the Niels Bohr Institute show that enormous quantities of random numbers can describe the way in which ...
New sound recording device helps doctors study link between cough and reflux
2010-09-28
Coughing episodes are closely related to gastroesophageal reflux symptoms in patients who experience chronic cough, irrespective of other diagnoses, according to a new study in Gastroenterology, the official journal of the American Gastroenterological Association (AGA) Institute. Gastroesophageal reflux occurs when the acid contents of the stomach back up, or reflux, into the esophagus. This typically produces heartburn, a burning sensation below the sternum where your ribs come together.
"This is the first study to investigate the temporal relationship between cough ...
Gigantic mirror for X-radiation in outer space
2010-09-28
It is to become the largest X-ray telescope ever: The International X-Ray Observatory (IXO), which has been planned in a cooperation between NASA, ESA and Japan's Aerospace Exploration Agency JAXA, will be launched into space in 2021 and provide the world with brand new information about black holes and, thus, about the origin of the universe. Its dimensions are gigantic: The surface of the mirror alone, which is to capture, for example, the cosmic X-radiation of black holes, will be 1300 m2 in size. It will consist of commercially available silicon wafers with pores of ...
A study analyzes consumer protection laws in Spain
2010-09-28
The idea behind this research arose because of the huge disparity in existing laws regulating the area of consumer protection, which made it necessary, according to the researchers, to carry out a systematic study to develop a "general report" which would gather the common principles and regulations regarding the different laws governing consumer protection. During the time this research study was underway, the Texto Refundido de la Ley General para la Defensa de los Consumidores y Usuarios (Consolidated Text of General Law of Consumer Protection) (LGDCU) was published; ...
Quantum physics: Flavors of entanglement
2010-09-28
Entanglement is a fascinating property connecting quantum systems. Albert Einstein called it the "spooky action at a distance". This bizarre coupling can link particles, even if they are located on opposite sides of the galaxy. The strength of their connections is behind the promising quantum computers, the dream machines capable of quick and efficient computations.
The team lead by Rainer Blatt at the Institute of Experimental Physics of the University of Innsbruck has been working very successfully towards the realization of a quantum computer. In their recent study, ...
Medical profession needs special training to handle self-harm, says international review
2010-09-28
Healthcare professionals are still not receiving the appropriate training and support they need to help people who self-harm and this can result in negative attitudes and inadequate levels of care.
Those are the key findings of a research review carried out by mental health specialists from the University of Nottingham, UK, and published in the October issue of the Journal of Psychiatric and Mental Health Nursing.
Staff nurse Jo McHale and lecturer Anne Felton studied 19 papers from the UK, Australia, Sweden and Ireland, dating from 1998 to 2009 and covering the views ...
Spaniards choose stable jobs over ones related to their training
2010-09-28
"If you study, you are more likely to get a stable job, even if it doesn't have anything to do with your training". This is the thinking of workers living in Spain, according to a research study by the Pompeu Fabra University (UPF), which studied the level of over-education in Spain, Italy and France, and the relationship between this and temporary work.
"This can be explained by the high levels of employment insecurity in Spain in comparison with other European countries", Luis Ortiz, author of the study and a researcher at the UPF, tells SINC.
The study, which has ...
Novel mechanism discovered for communication between proteins that cause 'cell suicide'
2010-09-28
A recent study undertaken by investigators at five research centres, amongst which is the CSIC-University of the Basque Country Biophysics Unit, provides new clues for the understanding of the 'cell suicide' process. The research was published in the latest issue of the prestigious Cell journal.
Our bodies daily eliminate in a controlled manner more than 100 million defective cells, by means of a procedure known as 'cell suicide' or apoptosis. This is a highly complicated process, any imbalances thus arising causing serious diseases, prominent amongst which is cancer. ...
Red light regulates nectar secretion
2010-09-28
Flowering plants produce nectar to attract insect pollinators. Some plant species, such as Lima bean, also secrete nectar from so-called extrafloral nectaries to attract ants which in turn fend off herbivores. Scientists of the Max Planck Institute in Jena, Germany, have discovered that the production of extrafloral nectar is light dependent. They have shown that the plants are able not only to distinguish between day and night, but also to adapt their nectar secretion to current light conditions by using a special photoreceptor, the phytochrome. Phytochrome probably influences ...

Computer model shows US vulnerable to MDR-TB epidemic
2010-09-28
While the U.S. has made great progress in the prevention and treatment of tuberculosis, the nation has become more susceptible to potential epidemics of multidrug-resistant tuberculosis (MDR-TB), according a study led by Johns Hopkins researchers. Computer simulations show that as TB prevalence falls, the risk for more extensive MDR-TB increases. In addition, the simulation also showed that higher detection of TB cases without proper treatment of cases also increased risk. The study findings are published in the September 22 edition of the journal PLoS ONE. An interactive ...

Elevated nitrogen and phosphorus still widespread in much of the nation's streams and groundwater
2010-09-28
Elevated concentrations of nitrogen and phosphorus, nutrients that can negatively impact aquatic ecosystems and human health, have remained the same or increased in many streams and aquifers across the Nation since the early 1990's, according to a new national study by the U.S. Geological Survey.
"This USGS report provides the most comprehensive national-scale assessment to date of nitrogen and phosphorus in our streams and groundwater," said Marcia McNutt, USGS Director. "For years we have known that these same nutrients in high concentrations have resulted in 'dead ...
Tile drainage directly related to nitrate loss
2010-09-28
URBANA – Tile drainage in the Mississippi Basin is one of the great advances of the 19th and 20th centuries, allowing highly productive agriculture in what was once land too wet to farm. In fact, installation of new tile systems continues every year, because it leads to increased crop yields. But a recent study shows that the most heavily tile-drained areas of North America are also the largest contributing source of nitrate to the Gulf of Mexico, leading to seasonal hypoxia. In the summer of 2010 this dead zone in the Gulf spanned over 7,000 square miles.
Scientists ...
Urban gardeners beware: There may be lead in your soil and food
2010-09-28
INDIANAPOLIS – Not since victory gardens helped World War II era Americans on the home front survive food shortages have urban gardens been as necessary and popular as they are today. With more food production in cities, the safety of the produce grown there becomes increasingly important.
As city dwellers across the country are harvesting fruits and vegetables for family consumption and planning ahead for the next planting season, geochemist Gabriel Filippelli, Ph.D., professor of earth sciences at the School of Science at Indiana University-Purdue University Indianapolis, ...
