It is expected the participation of the following guest speakers: Peer Bork, from EMBL in Heidelberg (Germany); Timothy Gardner, from the Boston University (USA); Mads Kaern, from the University of Ottawa (Canada); Nadav Kashtan, from the Weizmann Institute of Science in Rehovot (Israel); Patrick Lemaire, from the Developmental Biology Institute of Marseilles-Luminy (France); Martin Lercher, from the University of Bath (United Kingdom); Alfonso Martínez-Arias, from the University of Cambridge (United Kingdom); Uwe Sauer, from the Institute for Molecular Systems Biology-ETH in Zurich (Switzerland); Ricard V. Solé, from the Universitat Pompeu Fabra in Barcelona (Spain); Marc Vidal, from the Dana-Farber Institute in Boston (USA); Ron Weiss, from Princeton University (USA); Mark Isalan and James Sharpe, both from the Centre for Genomic Regulation in Barcelona (Spain).
Systems Biology is an emerging discipline that aims at a quantitative understanding of biological systems to an extent that one is able to predict its response to external (drugs) or internal (mutations) disturbances and, in the future, even to modify them rationally (Synthetic Biology). The most obvious applications of Systems Biology are in the field of medicine. At the moment, the way medicine works is by using very similar drugs and treatments for everyone. We are all aware of the multibillion losses that pharmaceutical companies have suffered in the last years due to the commercialization of drugs that, although beneficial for a large part of the population are harmful for certain groups of people. Treatment of diseases today remains still to a large extent the same as when aspirin was discovered. Essentially either serendipitously or through the identification of putative targets in basic research a massive screening is done helped or lead by design software, and candidate drugs are then tested on different systems to assess their toxicity and potency. Drugs that pass this stage are then validated by very costly medical trails involving thousands of patients.
All this procedure is very costly and inefficient and it is based on the assumption that human diseases can be cured with a single drug. However, it is quite obvious that the majority of us will not die because of a single faulty gene, but because of the combination of many small alterations on different genes (multifactorial diseases) combined with our life style. Multifactorial diseases are hard to treat since they involve more than one gene product in an organism, often working in different cellular pathways. Thus we need first to be able to understand in a global and quantitative way how a complex biological system as the human being operates, to be able to tackle in a rational way the treatment of complex diseases. This is precisely one of the aims of Systems Biology.

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,...
