This was the conclusion of a study undertaken with 8,556 participants by scientists of the University of Navarra, in collaboration with the University of Las Palmas de Gran Canaria and the Harvard School of Public Health (USA), and which demonstrates in a pioneering way the direct relationship between tobacco use and this disease.
The article, whose first author is Prof. Almudena Sánchez-Villegas, is based on research undertaken over the course of 6 years on university graduates with an average age of 42. "Over the course of the tracking and data collection stage, 190 smokers who initially did not present depression were diagnosed with this disease by a doctor. In addition, 65 who were not diagnosed indicated that they were taking antidepressants during this period,” indicated Miguel Ángel Martínez-González, director of the research project and Chair Professor of the Department of Preventive Medicine and Public Health.
Among the mechanisms that shed light on this relationship, he points to “genetic and/or environmental disposition, which will increase the probability that the tobacco habit is retained and that the user will suffer depression as an independent issue.”Lessening of physical activity
In addition, the researchers noted that an increase in tobacco use was correlated with a lessening of physical activity in the smoker’s free time.

Tiny pores at a cell's entryway act as miniature bouncers, letting in some electrically charged atoms--ions--but blocking others. Operating as exquisitely sensitive filters, these "ion channels" play a critical role in biological functions such as muscle contraction and the firing of brain cells.
To rapidly transport the right ions through the cell membrane, the tiny channels rely on a complex interplay between the ions and surrounding molecules,...
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...
