The article Increase of tobacco consumption and reduction of the physical activity practice level in Spanish adolescents: AVENA Study, published in the journal Nutrición Hospitalaria, has analysed the relationship between tobacco and sports in a sample of about 3,000 students from Granada, Madrid, Murcia, Santander and Zaragoza, who were applied a questionnaire to get to know their habits on this matter.
According to this research work, with the participation of the UGR Professors Pablo Tercedor, Palma Chillón, and Manuel Delgado, 59.2% of the adolescents are physically active, although there are significant differences according to sex (71.1% of the boys as against 46.7% of the girls). These percentages coincide with other similar studies carried out in the USA, although the results are below those obtained in France (where 75% of men play a sport, as against 58% of women).Girls smoke more
In the scientists’ opinion, these results show the importance of adopting measures to promote the practice of physical activity and eradicate tobacco consumption, as it has been proved how physical activity, diet and tobacco and alcohol consumption are related to obesity, diabetes, coronary disease, osteoporosis and cancer. Whereas the practice levels of physical activity in adolescents decrease as they get older, tobacco consumption increase, which reveals the importance of adopting intervention strategies on both conducts.
This work has also analysed the attitudes and motivations that encourage to tobacco consumption among the young, such as the use of this toxic substance as a mechanism to control body weight, a method to calm down, a curiosity or a with to feel older, among others.

The miniaturization of the current technology of storage media is hindered by fundamental limits of quantum mechanics. A new approach consists in using so-called spin-crossover molecules as the smallest possible storage unit. Similar to normal hard drives, these special molecules can save information via their magnetic state. A research team from Kiel University has now managed to successfully place a new class of spin-crossover molecules onto a surface and to improve the molecule’s storage capacity. The storage density of conventional hard drives could therefore theoretically be increased by more than one hundred fold. The study has been published in the scientific journal Nano Letters.
Over the past few years, the building blocks of storage media have gotten ever smaller. But further miniaturization of the current technology is hindered by...

Physicists in the Laboratory for Attosecond Physics (run jointly by LMU Munich and the Max Planck Institute for Quantum Optics) have developed an attosecond electron microscope that allows them to visualize the dispersion of light in time and space, and observe the motions of electrons in atoms.
The most basic of all physical interactions in nature is that between light and matter. This interaction takes place in attosecond times (i.e. billionths of a...
Transistors based on carbon nanostructures: what sounds like a futuristic dream could be reality in just a few years' time. An international research team working with Empa has now succeeded in producing nanotransistors from graphene ribbons that are only a few atoms wide, as reported in the current issue of the trade journal "Nature Communications."
Graphene ribbons that are only a few atoms wide, so-called graphene nanoribbons, have special electrical properties that make them promising candidates for the...
