La UGR, institución académica con la velocidad de red más rápida del mundo

Escrito por

La Universidad de Granada (UGR) se convierte en la institución académica con la velocidad de red más rápida del mundo. La nueva RedUGRNova cuenta con una conexión de 160 Gigabites por segundo (Gbps), una velocidad hasta 16 veces más potente que la que tienen la mayoría de las universidades españolas.

La Universidad de Granada (UGR) ha renovado la infraestructura de su red informática hasta alcanzar una conexión de 160 Gigabites por segundo (Gbps), lo que la convierte en la institución académica con la velocidad de red más potente del mundo. La conexión de la UGR es, desde esta semana, hasta 16 veces más rápida que la que tienen la inmensa mayoría de las universidades españolas. Además, se ha incrementado notablemente la seguridad de la red frente a contingencias en situaciones críticas de malfuncionamiento de algún sistema o infraestructura: la nueva es 10 veces más segura.

Esta red de nueva generación ha sido denominada «RedUGRNova», y cuenta con nodos de red que incorporan procesadores redundantes y de mayor capacidad y tarjetas de conectividad Gigabit Ethernet a 40 Gbps para establecer enlaces agregados, lo que le permite alcanzar una conexión en el núcleo troncal de red de 160 Gbps. Gracias a esta mayor capacidad, la UGR puede proporcionar a la comunidad universitaria el acceso a los recursos docentes y de investigación con la máxima velocidad, además de facilitar a los investigadores una colaboración sin interrupciones con centros ubicados dentro y fuera de España.

En los últimos años, la Universidad de Granada ha realizado una importante inversión económica para conectar entre sí más de 70 edificios repartidos en sus ocho campus (cinco en Granada, uno en Ceuta, otro en Melilla y otro virtual inalámbrico), a través de más de 2.000 kilómetros de cable de fibra óptica. Con esta medida, que ha permitido poner en marcha ahora la RedUGRNova, la Universidad de Granada ahorrará más de 1,2 millones de euros al año (cerca de 100.000 euros mensuales).

Como explica Antonio Ruiz Moya, Jefe de Servicio de Redes y Comunicaciones en la Universidad de Granada, «la tecnología aplicada, basada en desarrollos de última generación de la multinacional Cisco, y la colaboración del integrador nacional Acuntia, nos permiten disfrutar de una única red con la máxima disponibilidad, escalabilidad, rendimiento, control y seguridad en todos nuestros campus, además de simplificar la integración de los servicios universitarios, unificar su gestión y garantizar las comunicaciones internas y externas con independencia de su consumo de ancho de banda ahora y en el futuro».

En Andalucía, a 10 Gbps

Por su parte, el delegado del rector para las TIC, José Luis Verdegay Galdeano, explica que, en la actualidad, las universidades públicas andaluzas están conectadas entre sí a una velocidad de 10 Gbps, a través de la Red Informática Científica de Andalucía (RICA), dependiente de la Junta de Andalucía. «La Universidad de Granada cuenta con una red interna de 160 Gbps, es decir, 16 veces más rápida que la andaluza, lo que nos da un referente de la enorme importancia que tiene esta medida».

Verdegay agradece «el excelente trabajo» realizado por el Servicio de Redes y Comunicaciones en la Universidad de Granada, «que ha permitido colocar a nuestra Institución a la vanguardia mundial en el ámbito de las redes informáticas».

Tras la puesta en marcha de la RedUGRNova, la UGR trabaja ya en la creación de un Nodo de comunicaciones inalámbricas ubicado en el Centro de Telecomunicaciones del Monte Sombrero (en colaboración con el MADOC, Ministerio de Defensa) y otro situado en Sierra Nevada. «Ambos comenzarán a funcionar a lo largo de 2013, y servirán como soporte en el improbable caso de que se produjera un fallo masivo en todos los nodos de fibra óptica», afirma el delegado del rector para las TIC.

La RedUGRNova se compone de soluciones de routing, switching y seguridad de Cisco, y permitirá a la Universidad soportar internamente el crecimiento exponencial de usuarios y aplicaciones de alto rendimiento (HPC, High-Performance Computing) que requieren una mayor capacidad de red ahora y en el futuro, como servicios «en la nube» Cloud, voz sobre IP, videoconferencia en alta definición, mensajería instantánea, e-learning, biblioteca digital, Televisión por Internet (UGR Media) o almacenamiento en redes SAN, a la par que simplifican el control y la monitorización de recursos.

Este proyecto está encuadrado en las estrategias y objetivos planteados dentro del CEI BioTic GRANADA, recientemente calificado con la máxima puntuación por la Comisión Internacional encargada de evaluar el proyecto.

No todas las células madre son eficaces en medicina regenerativa

Escrito por

Científicos de la Universidad de Granada (UGR) y de la Universidad de Alcalá (UAH) concluyen que, en contra de lo que se pensaba, sólo un grupo de las células madre extraídas del cordón umbilical y mantenidas en cultivo en el laboratorio son útiles para su posterior aplicación terapéutica. Su trabajo ha sido publicado recientemente en la prestigiosa revista Tissue Engineering.

Científicos de las universidades de Granada y Alcalá han demostrado que no todas las células madre que se aíslan en un laboratorio tienen la misma eficacia a la hora de emplearlas en medicina regenerativa y en la construcción de tejidos artificiales. En un trabajo publicado recientemente en la prestigiosa revista Tissue Engineering han demostrado que, en contra de los que se pensaba hasta ahora, únicamente un grupo de las células madre extraídas del cordón umbilical y mantenidas en cultivo en el laboratorio son útiles para su posterior aplicación terapéutica.

En la actualidad, el cordón umbilical constituye una importante fuente de células madre para la medicina regenerativa y la construcción de tejidos artificiales. De los distintos tipos de células madre existentes en el cordón, las denominadas ‘células madre de la gelatina de Wharton’ están despertando un gran interés en la medicina regenerativa debido a su fácil accesibilidad, su gran potencial para diferenciarse hacia tejidos muy distintos y por poseer propiedades inmunológicas privilegiadas.

Mediante una combinación de experimentos que conllevan investigaciones microscópicas y microanalíticas, y el estudio de los genes implicados en la viabilidad celular, los investigadores han establecido que solo un grupo de las células madre extraídas del cordón y mantenidas en cultivo en el laboratorio son útiles para su aplicación terapéutica.

CÉLULAS MÁS IDÓNEAS

La importancia del trabajo, que la revista destaca como el más relevante de su último número, radica en la posibilidad de seleccionar para la ingeniería tisular y la medicina regenerativa las células madre más idóneas y eficaces de la gelatina de Wharton del cordón umbilical. El artículo explica por qué se han obtenido hasta ahora resultados contradictorios cuando se utilizaban estas células, ya que no se había seleccionado previamente en dicha población el grupo de células más idóneas.

La investigación realizada en la UGR y en la UAH abre la posibilidad de seleccionar también subgrupos de células en otras poblaciones de células madre de tejidos diferentes para aumentar la eficacia terapéutica en distintos protocolos de medicina regenerativa.

El grupo de investigación Traslacional en Biomateriales e Ingeniería Tisular de la Universidad de Alcalá, que dirigen los catedráticos Julia Buján Varela y Juan Manuel Bellón Caneiro, ha realizado esta investigación conjuntamente con el grupo de investigación de Ingeniería Tisular del departamento de Histología de la Universidad de Granada, que dirige el profesor Antonio Campos Muñoz.

The nose knows: Pinocchio effect reveals liars

Escrito por

Applying thermography techniques to the field of psychology, Spanish scientists have observed the «Pinocchio effect,» where a person’s nose becomes warmer when they are lying. The researchers, from the University of Granada, also found that our face temperature drops when we are performing challenging mental tasks.

Thermography was developed in the USA during World War II to detect enemy movement at night and, now, researchers Emilio Gómez Milán and Elvira Salazar López are pioneering its use in measuring physiological changes under a variety of stimuli.

Salazar said that when we lie, the temperature around our nose rises and a part of the brain known as the insula is activated. The insula is a component of the brain reward system, and it only activates when we are experiencing «real» feelings. The insula is also involved in the detection and regulation of body temperature and there is a strong negative correlation between insula activity and temperature increase. «The more active the insula [the more real the feeling] the lower the temperature change, and vice versa,» she explained.

Salazar added that sexual excitement and desire can also be identified using thermography. «They induce an increase in chest and genital temperature. Our study demonstrates that – in physiological terms – men and women get excited at the same time, even although women say they are not excited or only slightly excited,» she noted. The researchers also demonstrated that thermography can be used to measure empathic states. Salazar said that in experiments where a subject received an electric shock to the arm, an empathic observer would experience a rise in temperature in their arm.

Researchers demonstrate that saliva analysis can reveal decision-making skills

Escrito por

A study conducted by researchers at the University of Granada Group of Neuropsychology and Clinical Psychoneuroimmunology has demonstrated that cortisol levels in saliva are associated with a person’s ability to make good decisions in stressful situations. To perform this study, the researchers exposed the participants (all women) to a stressful situation by using sophisticated virtual reality technology. The study revealed that people who are not skilled in decision-making have lower baseline cortisol levels in saliva as compared to skilled people. Cortisol –known as the stress hormone– is a steroid hormone segregated at the adrenal cortex and stimulated by the adrenocorticotropic (ACTH) hormone, which is produced at the pituitary gland. Cortisol is involved in a number of body systems and plays a relevant role in the muscle-skeletal system, blood circulation, the immune system, the metabolism of fats, carbohydrates and proteins and the nervous system. Recent studies have demonstrated that stress can influence decision making in people. This cognitive component might be considered one of the human resources for coping with stress. A Study on 40 Healthy Women To verify that decision-making skills might modulate human response to psychosocial stress, the University of Granada researchers evaluated the decision-making process in 40 healthy women. Participants were asked to perform the so-called Iowa Gambling Task. Next, participants were presented a stressful situation in a virtual environment consisting on delivering a speech in front of a virtual audience. Researchers evaluated the participants’ response to stress by examining the activation of the hypothalamic pituitary adrenal axis, and measuring cortisol levels in saliva at different points of the stressful situation. Professors Isabel Peralta and Ana Santos state that this study provides preliminary evidence on an existing relationship between decision-making ability –which may play a major role in coping with stress– and low cortisol levels in psychosocially stressful situations. This means that the effects of psychological stress on the health people with lower cortisol levels might be milder. More information: The paper «Can decision-making skills affect responses to psychological stress in healthy women?» was recently published in the prestigious journal Psychoneuroendocrinology.
