Navarre doctor Rosa María Alás Brun has shown, in her PhD thesis defended at the Public University of Navarre, that, despite contamination rates in Pamplona being very low, these still have an influence on death rates.
After analysing the development, between 1991 and 1999, of the levels of five of the most representative contaminants in Pamplona - particles in suspension, sulphur dioxide, oxides of nitrogen, carbon monoxide and ozone -, Rosa María Alás Brun holds that this level of contamination, despite being low (even below that of the minimum levels recommended by the latest directives of the European Union and the World Health Organisation), “has an influence on the rate of mortality of the population”.
In this vein, the various statistical analyses carried out show a relation “between the increases in the concentration of particles in suspension and the short-term increase in deaths in persons due to non-external causes: specifically cardiac and respiratory causes”.

Physicists of the University of Würzburg have made an astonishing discovery in a specific type of topological insulators. The effect is due to the structure of the materials used. The researchers have now published their work in the journal Science.
Topological insulators are currently the hot topic in physics according to the newspaper Neue Zürcher Zeitung. Only a few weeks ago, their importance was...
In recent years, lasers with ultrashort pulses (USP) down to the femtosecond range have become established on an industrial scale. They could advance some applications with the much-lauded “cold ablation” – if that meant they would then achieve more throughput. A new generation of process engineering that will address this issue in particular will be discussed at the “4th UKP Workshop – Ultrafast Laser Technology” in April 2017.
Even back in the 1990s, scientists were comparing materials processing with nanosecond, picosecond and femtosesecond pulses. The result was surprising:...

A multi-institutional research collaboration has created a novel approach for fabricating three-dimensional micro-optics through the shape-defined formation of porous silicon (PSi), with broad impacts in integrated optoelectronics, imaging, and photovoltaics.
Working with colleagues at Stanford and The Dow Chemical Company, researchers at the University of Illinois at Urbana-Champaign fabricated 3-D birefringent...
In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.
“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...
