Spanish researchers have measured CO2 levels for the past three years in the troposphere (lower atmosphere) over a sparsely inhabited rural area near Valladolid. The results, which are the first of their kind in the Iberian Peninsula, show that the levels rose "significantly" between 2002 and 2005. Over recent years, physicists and meteorologists have been trying to find out about carbon dioxide (CO2) levels, and how these have evolved in the troposphere over various urban and rural areas...

Drug dependency is a recurrent but treatable kind of addiction. However, not all people who are drug dependent progress in the same way once they stop taking drugs. A new study shows that, in the case of cocaine, a high score on the so-called 'scale of craving', an antisocial personality type and previous heroin abuse are the factors most commonly involved in people falling back into the habit. Ana L³pez, lead author of the study and a researcher at the University of Santiago de...

People would be willing to pay more for products that carry detailed nutritional information than for the so-called light items. Thus it has been confirmed by researchers from the University of Santiago de Compostela (USC) and the Centre for Agro-Food Research and Technology of Arag³n (CITA) in a new study on the nutritional labelling of breakfast biscuits. Based on 400 personal interviews of individuals in Zaragoza, "We made 1,600 observations; we included multiple choice questions so...

The conservation and restoration of photographs is a topic that, in general, has not been very much researched. For example, in the case of colored or illuminated photographs, there does not currently exist an appropriate methodology, given that it there is not sufficient information about their material characteristics and structure. All this makes it difficult to research techniques of conservation and restoration. Researcher at the University of the Basque Country (UPV/EHU), Ms Enara...

The European mink, Mustela lutreola, is a species catalogued as in danger of extinction, due to the large decline in their population over the past century. It is considered to be one of the most endangered mammals, both locally and internationally. The PhD by University of the Basque Country (UPV/EHU) researcher, Maria Teresa Cabria Garrido, the title of which is Development and application of molecular markers for the study of the biology and the conservation of the European mink, Mustela...

A research team from the University of Castilla-La Mancha (UCLM) has analyzed the presence of heavy metals in 12 species of mushroom collected from non-contaminated natural areas, and has found that the levels vary depending on the type of mushroom. The results of the study, which appears this month in the journal Biometals, show that the largest quantities of lead and neodymium are found in chanterelles. "The aim was to find out if there is a connection between the concentrations of specific...

Researcher Dr. David H. Hughes of the Air Force Research Laboratory in Rome, N.Y. is leading a team investigating long-distance, mobile optical links imperative for secure quantum communications capabilities in theater. Hughes and his Air Force Office of Scientific Research-funded team have conducted high data-rate experiments using an optical laser link, a tool which exploits the quantum noise of light for higher security. The system uses adaptive optics for transmission of high data-rate...

Sandia researchers have developed a process that can mix tiny volumes of liquid, even in complicated spaces. Researchers currently use all types of processes to try and create mixing, with only "mixed" success. "In small devices," says Sandia materials scientist Jim Martin "people have tried all kinds of pillars and mixing cells to initiate mixing, but these approaches don't work well." Researchers need simpler and more reliable ways to mix in tiny places such as micrometer-sized channels,...

A Spanish researcher has analyzed the preferences of wolves from the north east of the Iberian Peninsula to demonstrate that, in reality, their favorite prey are roe deer, deer and wild boar, ahead of domestic ruminants (sheep, goats, cows and horses). Wolves (Canis lupus) have been pursued by humans for centuries due to their supposed "addiction" to livestock. However, the study by Isabel Barja, sole author and researcher at the Universidad Aut³noma de Madrid [Autonomous University of...

Saroi is a general tool which, apart from dealing with errors, is used for making consultations about structure in the trees of analysis and for undertaking searches for linguistic structures in such trees. A research worker at the University of the Basque Country (UPV/EHU) has analyzed the existing tools for the detection and correction of syntactic mistakes. To detect errors of context "”for example, concordance errors"” it is necessary to analysis the tree structure of the...
