iSGTW interviews Jorge Gomes, member of the European Grid Infrastructure (EGI) executive board, ahead of next month’s EGI Conference in Lisbon, Portugal. He explains why it is vital to support research with grid computing, as well as with a range of related IT services. “In order for researchers to be able to collaborate and share data with one another efficiently, the underlying IT infrastructures need to be in place,” says Gomes. “With the amount of data produced by research collaborations growing rapidly, this support is of paramount importance.”

Monday 29 September marks the 60th anniversary of the founding of the European Organization for Nuclear Research, otherwise known as CERN, located near Geneva, Switzerland. A new book, entitled 'From Physics to Daily Life', highlights some of the many ways in which technology developed at CERN has impacted upon society at large.

Bob Jones, the head CERN openlab, writes in this book about the growth of distributed computing and the vital role this technology plays across a wide range of academic fields and business sectors.

The latest European Grid Infrastructure case study describes how researchers in The Netherlands have used the e-BioInfra Gateway to analyze brain scans from NATO soldiers deployed to Afghanistan. The team discovered that combat stress impairs cognition by affecting the midbrain and its link with the prefrontal cortex. While this effect was found to be largely reversible, it is thought that it could have an impact on the soldiers’ future social and cognitive functions.

Researchers have used grid computing resources provided by Metacentrum, the Czech national grid infrastructure, to help design toxic-chemical-eating bacteria. The team used a combination of grid-powered mathematical modeling and laboratory experiments to design and test a five-step metabolic pathway for a new bacterium. The predictions of the model were used to create bacterial strains containing the optimal enzyme ratios, and the behavior of these real-life bacteria matched predictions closely. The key is to balance the activity of multiple enzymes to keep the bacterium alive, while sustaining a high processing rate.

Last week, iSGTW attended the European Grid Infrastructure (EGI) Community Forum 2014 in Helsinki, Finland. The event saw the launch of the EGI Federated Cloud, as well as a range of exciting presentations about how grid and other e-infrastructures are being used to advance excellent science in Europe.

Since being launched in 1977, NASA's Voyager 1 and 2 probes have been on an epic journey to the very edge of our solar system. Now, Domenico Vicinanza has harnessed the power of grid computing to create an uptempo piece of classical music from the data collected by the probes.

Keith Cover of VU University Medical Centre explains how the computing power of the grid has been used to process thousands of MRI scans from patients with Alzheimer’s, opening the way to better evaluation of biomarkers for this disease in the future.

Cover and his team used open-source software to run analyses of brain imaging scans, in order to track volume changes caused by Alzheimer’s disease. Now the power of the grid has been used to test the accuracy of several software packages on a massive scale.

Liver fibrosis, a  kind of scarring of the liver's tissue, is usually diagnosed with a biopsy – an invasive surgical procedure to remove liver cells for lab testing. However, physicist Olivier Beuf believes that we can do better and has put together a team to develop an imaging technique that can be used in a clinical examination.

Using the European Grid Infrastructure, he and his team have developed a 3D map showing how fibrosis affects blood flow in a diseased liver. These 3D maps could provide a reliable alternative to the usual biopsy procedure and have the potential to improve patients' well-being, as well as our understanding of liver disease.

The HP-SEE project has now come to an end. The project has been working to establish high-performance computing infrastructure in south-east Europe, and has been supporting a wide range of research communities in the region in its use.

Through this work — as well as that of previous projects — significant steps have been taken towards achieving the European vision of inclusive and smart growth, based on knowledge and innovation.

With preparations for the Intergovernmental Panel on Climate Change's 5th Assessment Report now entering their final stages, find out how climate models have evolved in the last 40 years and how grid computing is helping to project future climate.

Eleni Katragkou, a climate scientist from the Aristotle University of Thessaloniki in Greece, discussed many of these issues during an exciting plenary session at the recent EGI Community Forum 2013.

Has big data now superseded the grid… and the cloud? Whether or not this is the case, it is vital that in moving from one paradigm to another we do not discard the experience and technology gained previously, says European Grid Infrastructure director Steven Newhouse.
