That is the opinion of Paloma Cariñanos González, researcher of the Department of Botany of the University of Granada, who takes part in the Master Degree in “Gardening, Landscaping and Public Space” organized by the UGR.
In Spain, between 30-35% of the population shows any type of allergy. A 20% of thempresetn allergy to pollen, a fact which has experienced an increase in the last years. In addition, pollen allergy is more frequent in women than in men; in children than inadults and in cities than in rural environments, due to the low-quality of the air for the presence of atmospheric pollutants.Alternative species
According to Cariñanos González, species such as cypress trees, privets, elm trees, plane trees, daisies or grass are commonly used by the administration when it comes to design urban green spaces. “All of them have been described as allergen plants, and they provoke serious damage to the people who suffer such problem”, says the UGR Professor.Allergy causes
The introduction of exotic species, which give rise to new types of allergy, and the interaction of the plants with other atmospheric pollutants, present in cities (such as ozone and carbon dioxide, as the particles derived from combustion in diesel engines may remain adherent to the surface of pollen grains increasing their allergen activity) are other of the factors which contribute to the allergic nature of the ornamental species.

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:...
Have you ever wondered how you see the world? Vision is about photons of light, which are packets of energy, interacting with the atoms or molecules in what...
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...
The Max Planck Institute for Physics (MPP) is opening up a new research field. A workshop from November 21 - 22, 2016 will mark the start of activities for an innovative axion experiment. Axions are still only purely hypothetical particles. Their detection could solve two fundamental problems in particle physics: What dark matter consists of and why it has not yet been possible to directly observe a CP violation for the strong interaction.
The “MADMAX” project is the MPP’s commitment to axion research. Axions are so far only a theoretical prediction and are difficult to detect: on the one hand,...
