The main problem, according to the experts, is not that women feel a lot of guilt (which they do), but rather that many males feel "too little". "Our initial hypothesis was that feelings of guilt are more intense among females, not only among adolescents but also among young and adult women, and they also...

The use of an electronic smelling system capable of discriminating which tomatoes, melons or other products have a more attractive aroma is a particularly valuable aid for agro-food firms. However, existing electronic noses do not "smell" in the same way depending on the laboratory conditions, and these conditions change throughout the day and from one day to another. In order to overcome these fluctuations, researchers from the Agro-Food Quality Improvement Group at the Universitat Jaume I...

In first-time experiments in the wild, a researcher at Brown University has discovered that a species of bat in Madagascar, Myzopoda aurita, uses wet adhesion to attach itself to surfaces. The finding explains why the bat "” unlike almost all others "” roosts head-up. It also helps to explain how it differs from a similar head-up roosting species. Results appear in the Biological Journal of the Linnean Society. There are approximately 1,200 species of bats worldwide. Of that...

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...
