However, so far there are no methods to test them systematically and at low cost for malfunctions and security vulnerabilities. Therefore, computer scientists from Saarland University are working on automatic methods of testing, which check complex web applications autonomously. For the first time, they will present this work at exhibition booth F34 in hall 26 at the computer fair Cebit. The trade show will take place from March 6 to 10 in Hannover.
“Ineffective and inefficient” is Valentin Dallmeier’s assessment of the methods that web developers and responsible project leaders rely on to try to find programming errors and security holes in web applications. Dallmeier is a postdoc working at the software engineering chair of Saarland University. Its main focus is systematic automated debugging. The developed methods are functioning very well with typical computer programs. Dallmeier and his colleague Martin Burger have built on that basis, and aim to develop a software system that will determine automatically why Web 2.0 applications fail.
“This is still done manually and therefore causes not only very high costs, but also high levels of risk for companies and the community,” Burger explains. He refers to an article from last December, which revealed that incorrect programming of the “Facebook” social network made it possible to access saved, private photos of members.
Dallmeier and Burger want to prevent such worst-case scenarios and other breakdowns through their software “Webmate.” Businesses and their responsible web administrators will only have to type in their Web address. Afterwards the system will automatically discover how the different components of the application are connected to each other and via which menus, buttons, and other control panels the users are interacting with the application.
Subsequently, it will generate and carry out test scenarios. If it discovers, for example, that the application is not compatible with a certain version of a browser, or a control panel no longer exists in a new version of the application, the system will inform the developer immediately — likewise if a database is not connected, a server does not respond, or a link is dead. The web developer should be able to repeat this test at any time.
In the future, the service will be offered to companies for a fee. The researchers want to promote the technology through their own business, and hope to receive a patent. They will found their own company within the next few months. Dallmeier, the leader of the project, is confident that it is possible to implement the software system soon. “We have done the basic work over the last three years, and we even did some feasibility studies,” he says. He estimates the market potential in Germany alone to be 120 million Euros annually.For further information please contact:

Staphylococcus aureus is a feared pathogen (MRSA, multi-resistant S. aureus) due to frequent resistances against many antibiotics, especially in hospital infections. Researchers at the Paul-Ehrlich-Institut have identified immunological processes that prevent a successful immune response directed against the pathogenic agent. The delivery of bacterial proteins with RNA adjuvant or messenger RNA (mRNA) into immune cells allows the re-direction of the immune response towards an active defense against S. aureus. This could be of significant importance for the development of an effective vaccine. PLOS Pathogens has published these research results online on 25 May 2017.
Staphylococcus aureus (S. aureus) is a bacterium that colonizes by far more than half of the skin and the mucosa of adults, usually without causing infections....
Physicists from the University of Würzburg are capable of generating identical looking single light particles at the push of a button. Two new studies now demonstrate the potential this method holds.

An international team of physicists has monitored the scattering behaviour of electrons in a non-conducting material in real-time. Their insights could be beneficial for radiotherapy.
We can refer to electrons in non-conducting materials as ‘sluggish’. Typically, they remain fixed in a location, deep inside an atomic composite. It is hence...
Two-dimensional magnetic structures are regarded as a promising material for new types of data storage, since the magnetic properties of individual molecular building blocks can be investigated and modified. For the first time, researchers have now produced a wafer-thin ferrimagnet, in which molecules with different magnetic centers arrange themselves on a gold surface to form a checkerboard pattern. Scientists at the Swiss Nanoscience Institute at the University of Basel and the Paul Scherrer Institute published their findings in the journal Nature Communications.
Ferrimagnets are composed of two centers which are magnetized at different strengths and point in opposing directions. Two-dimensional, quasi-flat ferrimagnets...
