A group of researchers at the Navarre Public University, together with technical experts from the Navarre Provincial Government, are evaluating the impact of agricultural activity on water resources, based on a Net of Experimental Catchment Areas that the Provincial Administration has installed in several areas of Navarre.
To put this project into effect, the Agricultural Non Point Source Pollution method is being used; AGNPS is a technology which has been developed by the Department of Agri

A new generation of materials inspired by the ancient Greeks have been developed by scientists for use in miniaturised devices. The materials are robust, flexible films with perforations on the nano scale and have nano coatings. They are environmentally safe and will enable ultra-fast optoelectronic communication. They are produced by the self-assembly of an intricate
Using a unique combination of ground-based and space-based tools, scientists have determined for the first time how drought conditions, and possibly carbon uptake, in the Amazon rainforest can be quantified over large forest areas from space. The results are published in the on-line early edition of the Proceedings of the National Academy of Sciences, April 5-9.
“Understanding the Amazon environment is an essential puzzle piece needed to understand how the biosphere interacts with the clima
Newly diagnosed breast cancer patients who test positive for a BRCA1 or BRCA2 gene mutation are twice as likely to opt for bilateral or double mastectomy, taking the most aggressive surgical stance to treat their current cancer and reduce their risk for future breast cancer.
The study, led by researchers at Georgetown University Medical Center’s Lombardi Comprehensive Cancer Center (LCCC) and published online today in the Journal of Clinical Oncology, is the largest to date that evalua
Researchers at Jefferson Medical College and Duke University have used gene therapy to help damaged heart cells regain strength and beat normally again in the laboratory. The work takes the scientists one step closer to eventual clinical trials in humans.
Walter Koch, Ph.D., director of the Center for Translational Medicine of the Department of Medicine at Jefferson Medical College of Thomas Jefferson University in Philadelphia, and his colleagues at Duke used a virus to carry a gene into t
Researchers at UT Southwestern Medical Center at Dallas are the first to use genetically engineered mice containing a fluorescent molecule to examine in real time the chemical reactions that result in smooth-muscle contraction.
Smooth muscle, found in the walls of blood vessels and in internal organs such as lungs, stomach and the bladder, contracts as the end result of a series of chemical reactions. In a new study, UT Southwestern researchers report that one set of chemical reactions resu
A certain species of tick has learned the secret to staying slim–by remaining virgins. Female ticks who mate will drink 100 times their weight in host blood, whereas virgins aren’t so gluttonous says a University of Alberta researcher who has discovered a protein that may offer clues to a $10 billion global tick problem.
“What happens is that a female will remain attached to a host, eating slowly and waiting to be fertilized,” said Dr. Reuben Kaufman from the U of A’s Faculty of
Gene cassettes using self-cleaving peptides allowed T lymphocytes to construct a key multi-protein immune receptor complex
A genetic trick used by viruses to replicate themselves has been adapted for laboratory use to build complex protein structures required by immune system cells, according to investigators at St. Jude Children’s Research Hospital.
This approach could also be used to develop new gene therapy vectors in cases when cells must be modified to make high le
Many cultures view body and soul as inseparable
Requests for organ donors must be tempered by a better understanding of cultural differences, says a U of T researcher.
“We’re seeing different cultural perceptions of life and death and that affects end-of-life decisions,” says Kerry Bowman, a U of T professor with the Joint Centre for Bioethics and the clinical ethicist at Mount Sinai Hospital. Health care workers need to be aware that not all cultures consider organ donatio
A rare celestial event was captured by NASA’s Chandra X-ray Observatory as Titan — Saturn’s largest moon and the only moon in the Solar System with a thick atmosphere — crossed in front of the X-ray bright Crab Nebula. The X-ray shadow cast by Titan allowed astronomers to make the first X-ray measurement of the extent of its atmosphere.
On January 5, 2003, Titan transited the Crab Nebula, the remnant of a supernova explosion that was observed to occur in the year 1054. Although Saturn and
When Dr. Robert Ballard went on a scientific expedition to Black Sea this past summer, he was able to take with him virtually any scientist or student who wanted to go. With the capability of Internet2 and a high bandwidth satellite link, scientists, for the first time, were able to work on the ocean floor from the comfort of their university laboratories.
In the April 6 issue of EOS, the weekly newspaper of the American Geophysical Union, Dr. Ballard, a University of Rhode Island geological
It all started with an aquarium his father bought for the family home in Venezuela. The fish swam and ate and created an environment that captivated the watchful eye of then-10-year-old Hernan Lopez-Fernandez.
“One of the first fish of my own was called a Texas Cichlid,” Lopez-Fernandez said. “I was hooked on fish.”
Little did the young South American boy realize the role Texas would play in his life. Now a doctoral student in Texas A&M University’s wildlife and fisheries sci
The simple act of requesting to sit in a nonsmoking section may have profound benefits beyond avoiding second-hand smoke, according to new findings by researchers at Fred Hutchinson Cancer Research Center.
Parents who routinely engage in such anti-smoking behaviors in front of their adolescent children – particularly parents who themselves smoke – appear to significantly reduce their offspring’s chances of becoming a smoker by their senior year in high school, report M. Robyn Andersen,
A new invention that could dramatically change the lives of millions of people administering medication at home, has received investment worth £120,000 from NESTA (the National Endowment for Science, Technology and the Arts) – the organisation that nurtures UK creativity and innovation.
A plaster that can be worn on the skin, containing a tiny pump, could soon be improving the quality of life for those on fertility treatments, or diabetics needing regular insulin.
The pioneering te
Home is the place we know best. The Milky Way, our Galaxy, is the exception to the rule, however: Our knowledge of our nearest stellar neighbours has long been seriously incomplete and – worse – skewed by prejudice concerning their behaviour. In the past, stars were selected for observation because they were thought to be ’interesting’ in some sense, not because they were typical of stars in general. Naturally, this gave a biased view of the evolution of our Galaxy – that serves as the prototype of
A novel method that uses bacteria to mine valuable minerals from the ocean has been developed. Nodules collected from the Indian Ocean seabed can be treated to extract scarce land-based minerals in an environmentally sound way, says research published in the Journal of Chemical Technology and Biotechnology.
Using the marine species Bacillus M1, Cobalt, Copper and Nickel can be extracted from the nodules at a near neutral pH and room temperature. In a single four-hour process, 45% Cobalt and
