Whether dealing with high-power particle accelerators, astronomical observatories or Earth-watching spacecraft, modern science involves vast volumes of information, and researchers require powerful Grid computing techniques to manage this data deluge.
And at a time when the research teams working on the biggest scientific problems of our time – from climate modelling to molecular biology or high energy physics - are larger and more diffuse than ever before, Grid computing offers a promising way for such groups to perform e-collaboration: forming virtual organisations able to remotely work together, sharing data, tools and resources. A two-day workshop at ESAs centre in Italy this week covered scientific and also industrial Grid computing applications, highlighting current systems as well as the likely course of future Grid development and applications. Around 40 local scientific researchers and representatives from industry gathered for the Grid and e-Collaboration for the Space Community workshop. The event took place on 2 and 3 February at the European Space Research Institute (ESRIN) in Frascati overlooking Rome. A day of discussion was followed by a second day of tutorials in Grid use.
It was an appropriate locale because ESRIN is dedicated to Earth Observation data archiving and distribution, an increasingly demanding task. For example, in just under three years of Envisat satellite operations, two Petabytes of derived data have now been archived, enough information to fill 20 million filing cabinets. The need to handle these much data and make them available to users has led ESRIN to take up Grid technology. "We have begun an Earth Science Grid-On-Demand service based on our local Grid," explained organiser Luigi Fusco of ESRIN. "From this single site, users gain access to large volumes of Earth Observation data and can easily and quickly perform a variety of data reprocessing, including fine-tuning new algorithms to get optimal results." Applications so far include satellite image mosaicking to monitor changing global chlorophyll concentrations on a monthly basis and tracking iceberg movement in polar regions.

The formation of stars in distant galaxies is still largely unexplored. For the first time, astron-omers at the University of Geneva have now been able to closely observe a star system six billion light-years away. In doing so, they are confirming earlier simulations made by the University of Zurich. One special effect is made possible by the multiple reflections of images that run through the cosmos like a snake.
Today, astronomers have a pretty accurate idea of how stars were formed in the recent cosmic past. But do these laws also apply to older galaxies? For around a...
Just because someone is smart and well-motivated doesn't mean he or she can learn the visual skills needed to excel at tasks like matching fingerprints, interpreting medical X-rays, keeping track of aircraft on radar displays or forensic face matching.
That is the implication of a new study which shows for the first time that there is a broad range of differences in people's visual ability and that these...
Computer Tomography (CT) is a standard procedure in hospitals, but so far, the technology has not been suitable for imaging extremely small objects. In PNAS, a team from the Technical University of Munich (TUM) describes a Nano-CT device that creates three-dimensional x-ray images at resolutions up to 100 nanometers. The first test application: Together with colleagues from the University of Kassel and Helmholtz-Zentrum Geesthacht the researchers analyzed the locomotory system of a velvet worm.
During a CT analysis, the object under investigation is x-rayed and a detector measures the respective amount of radiation absorbed from various angles....
The quantum world is fragile; error correction codes are needed to protect the information stored in a quantum object from the deteriorating effects of noise. Quantum physicists in Innsbruck have developed a protocol to pass quantum information between differently encoded building blocks of a future quantum computer, such as processors and memories. Scientists may use this protocol in the future to build a data bus for quantum computers. The researchers have published their work in the journal Nature Communications.
Future quantum computers will be able to solve problems where conventional computers fail today. We are still far away from any large-scale implementation,...
