Arranca un curso virtual sobre Gemología en la Universidad de Granada

El Departamento de Mineralogía y Petrología de la Universidad de Granada ha organizado la cuarta edición del curso ‘Gemología: conceptos básicos y reconocimiento de gemas’, el cual se realiza de forma virtual y garantiza una formación avalada por las asociaciones profesionales.

El curso, realizado en colaboración con la Asociación Española de Tasadores de Alhajas (AETA) y el ‘Gemmological Institute’ del HRD (Amberes, Bélgica), se estructura en dos módulos teóricos y uno práctico. En el primero se introducen conceptos básicos sobre la naturaleza cristalina de las gemas más importantes y de sus variedades, así como las propiedades físicas que permiten diferenciar unas de otras.

El módulo práctico está concebido para entrenar al alumno en el reconocimiento de gemas a partir del conocimiento de sus propiedades más importantes, según informa en una nota la Universidad de Granada.

El curso, en su conjunto, permitirá al alumno acceder a otros cursos de Gemología eminentemente prácticos como el que impartirá el HRD de Ámberes (Bélgica) en las instalaciones de la Universidad de Granada en el mes de junio, justo a continuación del curso virtual. Tanto AETA como el Instituto Gemológico del HRD colaboran con la Universidad de Granada para la realización de ambos cursos y emitirán conjuntamente los diplomas acreditativos de la realización de los mismos.

El plazo para inscribirse y solicitar beca está abierto hasta el 21 de diciembre, ya que el curso se iniciará en enero de 2013, aunque quedan muy pocas libres, debido al éxito de las tres ediciones anteriores y a que sólo se ofertan diez plazas para un curso de alto nivel que se realiza

Así se ha demostrado con los alumnos de las anteriores ediciones que han superado las pruebas de acceso a las prestigiosas aulas del ‘Institute of Gemology’ del HRD de Amberes, entre otros.

El curso sobre Gemología se impartirá de forma virtual, aunque estará en todo momento tutorizado por el profesor Fernando Gervilla Linares, catedrático de Cristalografía y Mineralogía de la Universidad de Granada y diplomado en Gemología por la Gemmological Association of Great Britain.

Study on ‘Pinocchio Effect’: Lying raises nose temperature

Spanish researchers studying thermography have confirmed the «Pinnocchio effect» which causes the nose temperature to raise when a person lies.
Emilio Gómez Milán and Elvira Salazar López, researchers at the University of Granada Department of Experimental Psychology, have confirmed the «Pinnocchio effect.» Although a person’s nose does not grow when they lie, its temperature increases.
Canal UGR reported research based on studying thermography, a technique based on determining body temperature, showed when a person lies they experience «an increase in the temperature around the nose and in the orbital muscle in the inner corner of the eye.»
The researchers explained: «When we lie on our feelings, the temperature around our nose raises and a brain element called ‘insula’ is activated. The insula is a component of the brain reward system, and it only activates when we experience real feelings (called ‘qualias’). The insula is involved in the detection and regulation of body temperature. Therefore, there is a strong negative correlation between insula activity and temperature increase: the more active the insule (the greater the feeling) the lower the temperature change, and viceversa.»

Pinocchio Effect: Nose Temperature Rises When People Lie, Says Study

It’s said that we can catch a liar if we closely follow the person’s physical and verbal signs. But reading these signs may be very difficult, and like Pinocchio’s, the nose is not going to grow either, every time a lie is uttered.

Guess what the researchers at the University Of Granada in Spain who applied the technique of thermography, have to say about the changes that take place in our body when we lie?

According to the researchers, when a person lies, the temperature around the nose and in the orbital muscle in the inner corner of the eye increases.

A brain element called «insula», which is central to the brain reward system, is activated only by real feelings. However, there is a negative correlation between insula activity and temperature increase in the sense that the more active the insula is, the lower the temperature change, and viceversa.

So when a person doesn’t experience real feelings and lies, there is not much of insula activity, and it induces a temperature increase, explain the scientists.

Using Thermography, Researchers Find Evidence Of The Pinocchio Effect

A breakthrough new study from the University of Granada has confirmed that Geppetto was right when he told Pinocchio that lying affects your nose, he was just wrong about how. The new study reveals that when a person lies, they suffer a «Pinocchio effect» – an increase in the temperature around the nose and in the orbital muscle in the inner corner of the eye. They also found that when a person performs a considerable mental effort, facial temperature drops. Conversely, facial temperatures rise when the person has an anxiety attack.

Researchers from the University of Granada’s Department of Experimental Psychology are pioneers in the application of thermography – a technique based on determining body temperature – to psychology. Thermography has applications in many fields such as general industry, building, and medicine. For example, thermographic cameras can be used to measure energy loss in buildings, indicating respiratory diseases in bovine animals or rabies in raccoons. Originally, thermography was developed by the U.S. to detect enemy combatants during WWII.

Researchers Emilio Gomez Milan and Elvira Salazar Lopez have obtained very innovative and interesting results. One of the interesting results is that sexual excitement and desire can be identified using thermography. Excitement and desire cause an increase in chest and genital temperature. Using this knowledge, the study shows that although women may say they are not excited, or only mildly excited – physiologically, men and women become excited at the same time.

The team has discovered that when a mental effort, such as performing difficult tasks, being interrogated, or lying, is made, facial temperatures change. Lying raises the temperature around the nose and activates a brain element called insula. Insula is a component of the brain’s reward system, which activates only when we experience real feelings, also known as qualias. The insula is involved in detecting and regulating body temperature, showing a strong negative correlation between insula activity and temperature increase. In other words, the more active the insula (the greater the feeling) the lower the temperature change, and vice versa.

The team also determined the thermal footprint of aerobic exercise and a variety of dance modalities such as ballet. They found that when a person is dancing flamenco, the temperature of the dancer’s forearms increases while the temperature of their buttocks decreases. Professor Salazar explains that each dance modality has a specific thermal footprint such as this one for flamenco.

Temperature asymmetries in both sides of the body, along with local temperature changes, are associated with the physical, mental and emotional status of the subject according to the study.

«The thermogram is a somatic marker of subjective or mental states and allows us to see what a person is feeling or thinking,» Professor Salazar states.

Thermography is useful in evaluating emotions, the study claims, because the facial thermal pattern is different. It can also be used to identify emotional contagion.

«For example, when a highly empathic person sees another person having an electric discharge in their forearm, they become infected by their suffering and temperature in their forearm increases.»

The body does not properly regulate temperature in certain neurological diseases such as multiple sclerosis. This can be detected by the thermogram. Other applications include determining body fat patterns – useful in weight loss and training programs – and assessing body temperatures in celiac and anorexia patients.

‘Hot nose may be tell-tale sign of a liar’

Telling lies may not make your nose grow like Pinocchio’s, but it does leave the tip of your nose hotter, scientists claim.

Researchers said a rise in anxiety produced by lying will increase the temperature of the tip of your nose.

If you’re worried that your fib will be uncovered, researchers suggest a way of cooling the nose down by making «a great mental effort».

Scientists, from the University of Granada, discovered the phenomenon by using thermal imaging cameras to monitor volunteers, the ‘Online Media’ reported.

They have dubbed it «The Pinocchio Effect», in honour of the 19th century Italian tale of the wooden puppet whose nose grew when he failed to tell the truth.

Emilio Gomez Milan and Elvira Salazar Lopez suggest that the temperature of the nose increases or decreases according to mood, as does the orbital muscle area in the inner corner of the eyes.

They also said thermal imaging can detect sexual desire and arousal in men and women, indicated by an increase in temperature in the chest and genital areas.

The technique also allowed researchers to produce thermal footprints and body patterns with specific temperature changes for aerobic exercise and distinct types of dance, such as ballet.

«When someone dances Flamenco, the temperature in their buttocks lowers and it rises in their forearms. This is the thermal footprint for Flamenco, although each type of dance has its own,» researchers said.

Researchers discovered that when the volunteers lied about their feelings, the brain’s insular cortex was altered.

«The insular cortex is involved in the detection and regulation of body temperature, so there is a large negative correlation between the activity of this structure and the
magnitude of the temperature change.

«The more activity in the insular cortex (the higher the visceral feeling), lower heat exchange occurs, and vice versa,» they said.

The ‘Pinocchio effect’: If you don’t tell the truth, your nose really could give you away

The story of Pinocchio, the wooden boy whose nose grew when he told a lie, has long served as a warning to youngsters to tell the truth or risk being found out.

Well it appears the story had a nugget of truth to it, with a new study now saying that when people tell a lie they indeed suffer a similar effect.

Psychologists investigating how mental states affect body temperature say that when people lie their noses and the region around the inner corner of their eyes begin to warm up.

Disney’s Pinnochio: The wooden boy’s nose grew longer and longer if he ever told a lie. Now a new study has shown that lying really does have an effect on our noses – by making it warm up

The team from the University of Granada, Spain, say this ‘Pinocchio effect’ is just one of a range of changes in body temperature related to feelings they have discovered using a technique called thermography.

They also found that when we perform a considerable mental effort our face temperature drops and when we have an anxiety attack our face temperature raises.

Rarely before used in psychological research, thermography uses specially adapted cameras to detect infrared radiation, producing images of objects based on their heat signature.

Thermographic cameras were developed in the U.S. during the Second World War and these days are used in such diverse tasks as measuring energy loss in buildings, indicating respiratory diseases in cows or rabies in raccoons.

University of Granada’s Emilio Gómez Milán and Elvira Salazar López are among the first to applying thermography to psychological research.

They found that when we misrepresent our true feelings – when we lie, in other words – the temperature around our nose raises and a brain element called ‘insula’ is activated.

The insula is a component of the brain reward system, and it only activates when we experience real feelings (called ‘qualias’). It is also involved in the detection and regulation of body temperature.

Therefore, there is a strong negative correlation between insula activity and temperature increase: the more active the insule (the greater the feeling) the lower the temperature change, and vice versa, the researchers state.

Researchers also determined the thermal footprint of aerobic exercise and different kinds of dance. When a person is dancing flamenco, for example, the temperature in their buttocks drops and increases in their forearms.

That is the thermal footprint of flamenco, and each dance modality has a specific thermal footprint, Professor Salazar explained.

The researchers have demonstrated that temperature asymmetries in both sides of the body and local temperature changes are associated with the physical, mental and emotional status of the subject.

Because of this, the thermogram is a somatic marker of subjective or mental states and allows us see what a person is feeling or thinking, Professor Salazar added.

Giving the game away: When we misrepresent our true feelings – when we lie, in other words – the temperature around our nose raises and a brain element called ‘insula’ is activated

Also, the researchers say, thermography is useful for evaluating emotions (since the face thermal pattern is different) and identifying emotional contagion.

For example, when a highly empathic person sees another person having an electric discharge in their forearm, they become infected by their suffering and temperature in their forearm increases.

In patients with certain neurological disease such as multiple sclerosis, the body does not properly regulates temperature, which can be detected by a thermogram.

Thermography can also be applied to determine body fat patterns, which is very useful in weight loss and training programs. It can also be applied to assess body temperature in celiac patients and in patients with anorexia.

Most interestingly, the researchers showed sexual excitement and desire can be identified in men and women using thermography, since they induce an increase in chest and genital temperature.

Their study demonstrates that – in physiological terms, at least – men and women get excited at the same time, even although women may say they are not excited or only slightly excited.
