Sandia National Laboratories researcher Steve Plimpton, who led development of a widely used computer code that models how materials behave, has been invited to present a keynote lecture at the Feb. 27-March 3 Minerals, Materials & Materials Society (TMS) meeting in San Diego. Plimpton developed the LAMMPS molecular-dynamics software code. The acronym LAMMPS (Large-scale Atomic/Molecular Massively Parallel Simulator) is also a pun on the word "lamp," a device that brings light to dark...

Fire, cattle and even prairie dogs all could play a role in sustaining the biodiversity of the western Great Plains, according to a U.S. Department of Agriculture (USDA) researcher. As large grazers, cattle now perform the historical role of buffalo on the Great Plains. Ecologist David Augustine and his colleagues-in collaboration with state, federal, and university researchers-have results from several studies over the past 13 years showing that fire, cattle and prairie dogs together...

An international research team, with Spanish participation, has discovered a new species of mollusk, Polyconites hadriani, in various parts of the Iberian Peninsula. The researchers say this species, which is the oldest in its genus, adapted to the acidification of the oceans that took place while it was in existence. This process could now determine the evolution of modern marine systems. The new species Polyconites hadriani, which was discovered in 2007, has been crowned the oldest in the...

Ensuring the sustainability of the products we use is a fundamental challenge for society, and is becoming ever more important for consumers and companies. A researcher from the University of Santiago de Compostela (USC) has come up with an eco-labeling system that provides environmental information, showing the carbon footprints generated by the goods and services in question during their "life cycle". "This study provides an alternative means of efficiently communicating environmental...

Pure organic compounds that glow in jewel tones could potentially lead to cheaper, more efficient and flexible display screens, among other applications. University of Michigan researcher Jinsang Kim and his colleagues have developed a new class of material that shines with phosphorescence---a property that has previously been seen only in non-organic compounds or organometallics. Kim and his colleagues made metal-free organic crystals that are white in visible light and radiate blue, green,...

The link between deficits of omega-3 poly-unsaturated fatty acids (AGPO-3) and the onset of depressive disorders is not new in the medical field. However, what has not been known until now is the brain mechanism by which diet can condition mental health to a certain extent. Research undertaken by scientists in Bordeaux (France) and at the Faculty of Medicine and Odontology of the University of the Basque Country (UPV/EHU) and published in Nature Neuroscience, provides new clues to...

In Spain it is relatively common to come across petrol stations surrounded by houses, particularly in urban areas. Researchers from the University of Murcia (UM) have studied the effects of contamination at petrol stations that is potentially harmful to health, which can be noted in buildings less than 100 metres from the service stations. "Some airborne organic compounds "“ such as benzene, which increases the risk of cancer "“ have been recorded at petrol stations at levels...

Estuaries are highly appropriate systems for evaluating contamination. They are areas of accumulation of sediments and, effectively, numerous contaminants are found associated with these sedimentary particles. For a comprehensive evaluation, it is important to undertake studies on the effects of the contaminants in the environment; the toxicity trials enabling the quantification of such effects. These trials involve exposing organisms to sediments suspected of being contaminated, in order to...

We have developed an 'anytime' intelligence test, in other words a test that can be interrupted at any time, but that gives a more accurate idea of the intelligence of the test subject if there is a longer time available in which to carry it out", Jos© Hernández-Orallo, a researcher at the Polytechnic University of Valencia (UPV), tells SINC. This is just one of the many determining factors of the universal intelligence test. "The others are that it can be applied to any subject...

Unemployment has a negative impact on a worker's future salary if it continues for a long time, particularly in countries such as Spain, Italy and Portugal. This is the conclusion of a study carried out by Spanish researchers, who have analysed the impact of job loss on relative salaries in six European countries. "Out of the countries studied, Spain, Italy and Portugal are the European Union countries in which long-term unemployment is likely to have the most negative effect on salary when...
