Miguel Ángel Muñoz García, from the Department of Personality, Evaluation and Psychological Treatment of the University of Granada has carried out this study, under the direction of the Professors Jaime Vila Castelar and Mª Carmen Fernández Santaella.
”Craving" is an expression used to define an uncontrollable desire for the administration or consumption of an addictive substance. It is usually used in situations of alcohol or nicotine dependence and it is considered as a pathology that affects cognitive resources, as it has an obsessive component.
180 cocaine users
The researchers of the University of Granada analysed, with the help of a device, 180 regular takers of an addictive substance (cocaine, in this case), to study the emotional mechanisms triggering the addiction for the substance. This study has helped to establish the behavioural mechanisms in cocaine addiction, and consists of the emotional control of different consumption situations.
These results have been the basis of a series of studies with smokers, in withdrawal for 8 hours, to measure the physiological and emotional variables present in withdrawal symptoms using a machine (a polygraph) to estimate the emotional mechanisms responsible for the addiction to that substance. The smokers were shown several images (48) connected with situations that produce desire (related with leisure, free time, coffee…), analysing the heart´s defensive cardiac response produced as well as the startle response.
Lastly, brain modifications associated with emotional responses of frustration and impulsiveness in smokers in withdrawal were studied. This system was also used for regular smokers.
Miguel Ángel Muñoz García states that this research has studied for the first time behavioural mechanisms involved in the tobacco craving process determining the brain areas and body responses connected with the compulsive behaviour provoked by tobacco.Reference

Researchers at the University of New Hampshire have captured a difficult-to-view singular event involving "magnetic reconnection"--the process by which sparse particles and energy around Earth collide producing a quick but mighty explosion--in the Earth's magnetotail, the magnetic environment that trails behind the planet.
Magnetic reconnection has remained a bit of a mystery to scientists. They know it exists and have documented the effects that the energy explosions can...
Biochips have been developed at TU Wien (Vienna), on which tissue can be produced and examined. This allows supplying the tissue with different substances in a very controlled way.
Cultivating human cells in the Petri dish is not a big challenge today. Producing artificial tissue, however, permeated by fine blood vessels, is a much more...
Faster and secure data communication: This is the goal of a new joint project involving physicists from the University of Würzburg. The German Federal Ministry of Education and Research funds the project with 14.8 million euro.

On Saturday, 10 November 2018, the research icebreaker Polarstern will leave its homeport of Bremerhaven, bound for Cape Town, South Africa.
When choosing materials to make something, trade-offs need to be made between a host of properties, such as thickness, stiffness and weight. Depending on the application in question, finding just the right balance is the difference between success and failure
Now, a team of Penn Engineers has demonstrated a new material they call "nanocardboard," an ultrathin equivalent of corrugated paper cardboard. A square...
