iSGTW Feature - Mission: HealthGrid

  Feature - Mission: HealthGrid HealthGrid brings together interested parties from across the globe to work towards improved biomedical research through the use of grid technologies. Image courtesy of HealthGrid The HealthGrid initiative began in 2002, created by a scientific community driven to develop health-related grid technology at an international level. In April 2003 this initiative became the HealthGrid association, a community that now includes about 500 people from 30 countries across the globe. The HealthGrid community comprises two main arms: the HealthGrid international association, which promotes the use of grids in the international healthcare and biomedical sectors; and the HealthGrid.US alliance, which represents HealthGrid in the U.S. By working together, it has become easier to share and communicate knowledge and technology, to guarantee effective collaboration between business and collaborative, free and open source models, and to provide trustworthy resources. Together, HealthGrid can ensure the

  Image of the week - The micro-world of muscle cells These four visualizations show four sections of a muscle cell, each comprising several saromeres. Different colours indicate different organelles, including the myofibrillar system, sarcoplasmic reticulum, mitochondria and t-tubules. The cell envelope is rendered transparently.Image courtesy of GeomCell Enter the micro-world of your muscle cells, and you’ll find the entire length of a muscle “fiber” is actually a single cell. Called “skeletal muscle cells,” these giants are comprised of a number of repeating units, called sarcomeres, which contain cellular organelles such as myofibrils, mitochondria, t-tubules and sarcoplasmic reticulum.These organelles, even if of the same type, vary widely in their size, shape and location within the cell. Moreover, they often display complex spatial relationships. To understand the complexity of a muscle cell, realistic computer models are instrumental and may serve as a virtual cell

Link of the week - Salute to SALUTE

The Bulgarian team in charge of the SALUTE project is developing algorithms for studying quantum effects in semiconductor structures. These effects influence the design of nano-devices with improved performance.Images courtesy of SALUTE and Obscura

SALUTE—or Stochastic ALgorithms for Ultra-fast Transport in sEmiconductors—is a pilot grid application developed to solve computationally intensive problems in semiconductor physics.
Semiconductors—materials that can both conduct and insulate electricity—are invaluable to modern electronics. Their ability to conduct depends on the ability of “carriers”—electrons or phonons—to transport electrical charge.This carrier transport occurs on a quantum level: the temporal scale is so short it is measured in femtoseconds, where one femtosecond is 10-15 seconds, or one millionth of a nanosecond.
Simulations on this sort of scale rely on complicated integral eq

iSGTW Feature - Never-born proteins: predicting protein structures from your web browser

Feature - Never-born proteins: predicting protein structures from your web browser By predicting the structure and functional properties of “never born proteins” scientists can learn more about the structure and function of actual existing proteins.Image courtesy of INFN While the number of known natural protein sequences is quite large, it is infinitely small compared to the number of proteins theoretically possible using the 20 natural amino acids. Thus, there exist a huge number of protein sequences that have never been observed in nature, the so-called “never born proteins.” If we can study the structural and functional properties of these “never born proteins,” we can improve our knowledge of the fundamental properties that make existing protein sequences so unique. Where these studies would take years on a single CPU, grid infrastructures make it feasible to approach this problem in an acceptable time frame.

  Feature - Powerful pollution model moves to the grid High ozone levels threaten Bulgaria’s most important agricultural crop, wheat, with yields down by ten to twenty percent.Image courtesy Tzvetan Ostromsky In January 2008, Bulgarian authorities installed a public air pollution monitoring system in Sofia, the country’s capital. The system allows passing citizens to check air quality and keeps authorities informed of current pollution levels.  Computer scientist Tzvetan Ostromsky is also keeping an eye on pollution levels. Ostromsky is working at the Bulgarian Academy of Sciences to gridify a large-scale air pollution model. Called the Danish Eulerian model, it combines data on convection, diffusion, precipitation, emissions and more to predict future air pollution trends.“For a small country like Bulgaria it’s especially important to know what pollutants we’ll receive and from where,” says Ostromsky. “Emissions can travel thousands of kilometers—most of what Bulgaria get

iSGTW Feature - Our powers combined: gLite, Globus and Unicore play ball

i  Feature - Our powers combined: gLite, Globus and Unicore play ball The OMII-Europe team will celebrate the close of the project’s first phase in late April by releasing five interoperable software components that will give scientists the ability to combine the middleware powers of gLite, Globus and Unicore. Images courtesy of Sergio Andreozzi Connectivity and sharing lie at the heart of grid technology, yet ironically, the grid world can be a lonely place for a scientist. Researchers are limited to the storage, databases and processing power made available by their own particular grid middleware. This means each grid platform becomes the equivalent of an independent city-state. If you’ve ever felt the need to tunnel under your own city to visit other middleware dominions, then you’ll be interested in some new software that can let you do just that. In late April, OMII-Europe will celebrate the close of its first phase by releasing five interoperable software components that allow grid users to work acros

Image of the week - Window to a molecular world  The Vaccinia virus, a bundle of DNA comprising 250 genes, is a member of the poxvirus family and was key to World Health Organization efforts to eradicate smallpox. This image was produced using EGEETomo: grid-powered electron tomography.Image courtesy of Fernández, J.J.Electron tomography, also known as ET, provides researchers with a tiny window on to the alien world of molecular biology. The technology works by shooting electron beams through super-slim samples at different angles, producing data that can be pieced together to produce a three-dimensional structure. The technology is well suited to biological specimens such as chromosomes and viruses, providing nano-scale resolution for an all-new look at these target macromolecules.To achieve such resolution, ET demands sophisticated reconstruction algorithms. Where iterative algebraic algorithms yield high quality reconstructions, they are computationally expensive and their use requires high performance techniques.

iSGTW Feature - Evolving towards the future of science: genetic algorithms and grid computing

  Feature - Evolving towards the future of science: genetic algorithms and grid computing Computer engineers are mimicking biological genetics to create algorithms able to optimize solutions to computing problems. These “genetic algorithms” are possible thanks to the recent advent of cheap, readily available computing power, such as that available from computing grids. Stock image from sxc.hu Great innovations are not rare—we are surrounded by them. For inspiration, look not at buildings and machinery, but at plants and animals. Some of our best synthetic technologies copy what we see in nature: think of seed-styled Velcro, mollusk-inspired epoxy, air conditioning based on termite mounds and solar panels that imitate insect eyes. Now, a relatively new type of biomimicry is helping researchers find great ideas.Mutating the way to perfection  “Genetic algorithms” are search functions that “evolve” towards the optimum solution to a problem.

iSGTW Technology - YAIM: herding gLite configuration

  Technology - YAIM: herding gLite configuration And why a yak? The yak logo was provided by David O’Callaghan, in reference to the concept of “shaving the yak.” This was subsequently adopted as part of YAIM’s motto.Images courtesy of YAIM Setting up a grid site can present a pretty steep learning curve, and with more than 250 EGEE sites and new administrators arriving all the time, anything that eases the transition to becoming a fully fledged grid administrator is a big plus. That’s where YAIM comes in. EGEE’s gLite middleware takes its components from a number of different sources, each of which has its own configuration paradigm. To save administrators from having to learn the details of each service, the YAIM configuration utility does all the hard work, providing simple and separable installation and configuration methods. Built on basic Unix technology, YAIM offers administrators a familiar and uniform interface, also adding transparency to the process. YAIM is installed on every

  Feature - Computing the unseen: the search for dark matter Researchers are using the Collider Detector at Fermilab detector to help in the search for dark matter, hoping to observe a Bs particle decay, which could provide evidence of supersymmetry and dark matter. Image courtesy of FermilabThink you’ve seen it all? Think again. Everything we can see and detect makes up only four percent of the universe, according to Michael Weinberger, a physicist at Texas A&M University and member of the Collider Detector at Fermilab collaboration. Weinberger and his CDF colleagues are conducting a search that could shed light on the universe’s “dark matter”—material that doesn’t emit or reflect radiation but is predicted by astrophysical observations to outnumber visible matter by nearly six-to-one—and they are using grid technology to expedite their hunt. The elusive Bs decayThe key to the search is the ability to measure the rate at which Bs particles decay to form two muons. According to t
