The university’s Systems Biology Research Group is partnering eight other universities, institutes and companies in a €2.8 million European Commission initiative to build a data bank of information about a key aspect of research which is usually gleaned from animal tests.
The project will record, store and make available findings and predictions about levels of toxic harm of chemicals including many in everyday use in homes, shops, offices and other workplaces.
A major aim of the project, coordinated by the University of Warsaw, will be that firms making items such as medicines, tablets, cosmetics or weed-killer, will have easy computer access to information and forecasts about the toxicity of chemical compounds.
That, in turn, could lead to a cut in animal testing, since researchers will no longer have to duplicate experiments and could use the computer models to forecast properties of a new compound instead.
Research Fellow Mathilde Romberg, UU’s chief researcher on the project, said: “Chemical components influence our life in a multitude of ways – from drugs, new materials, fertilisers to cosmetics. It is essential to our well-being that we know about the properties of all these substances, whether they could do harm to our environment and, directly or indirectly, to humans.”
The project, Chemomentum ( www.chemomentum.org) pools the work of other experts in Estonia, France, Germany, Italy and Switzerland. The intention is to develop a computer software system that will provide manufacturers and industrial pharmacists with vital information – especially the level of toxicity – about ingredients they may be developing for use in a new product.
Ms Romberg said: “The toxicity of a compound is important for judging its harmfulness or also, in the context of drugs, its effectiveness. For instance, in the development process of a new drug to combat cancer, one looks for components which kill the specific type of cancer cells but leave other cells unaffected. The production of compounds used, say, for flavouring food or for removing weeds from your patio also has to involve strict evaluation of their toxic effects. Most of the testing involved the use of animals.”
Ms Romberg, who holds an MSc in Informatics from Aachen University of Technology in Germany, is leading research on UU’s component in the project – the compilation of one of the workpackages on knowledge-base and data management. She is a specialist in applying “grid computing” to computational biology. Grid computing is an evolving new technology which employs a combination of huge computation, massive data input and widespread collaborative systems to tackle grand-scale problems. Experts say the enormous potential of computer grids is likely to transform computer power available to the individual.
“Chemomentum involves connecting already-available data from experiments to develop the mathematical prediction models, and also computational resources for the different calculations,” she explained.
“Based on methods from distributed and grid computing, a user friendly system will be developed to help the chemical industry and European regulatory bodies to evaluate the substances and assess related risks, with fewer and fewer animal tests.”

The WHO reports an estimated 429,000 malaria deaths each year. The disease mostly affects tropical and subtropical regions and in particular the African continent. The Fraunhofer Institute for Silicate Research ISC teamed up with the Fraunhofer Institute for Molecular Biology and Applied Ecology IME and the Institute of Tropical Medicine at the University of Tübingen for a new test method to detect malaria parasites in blood. The idea of the research project “NanoFRET” is to develop a highly sensitive and reliable rapid diagnostic test so that patient treatment can begin as early as possible.
Malaria is caused by parasites transmitted by mosquito bite. The most dangerous form of malaria is malaria tropica. Left untreated, it is fatal in most cases....
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....
