ICE 4 defies wind and weather
Rail customers expect to be served by trains that function perfectly from the very first day of service. This is particularly true for the new Intercity platform that will be operated by Deutsche Bahn (DB). Expected to account for around 70 percent of revenue, the ICE 4 will be the backbone of DB's future long-distance service.
The ICE 4 in the Climatic Wind Tunnel – Snow, ice, wind, rain and blazing sun
The new Intercity train from Siemens underwent a 12-week comprehensive testing program at Rail Tec Arsenal (RTA) in Vienna. Here, in the longest climatic wind tunnel in the world, the train had to prove that it can operate flawlessly at speeds up to 200 kilometers an hour, at temperatures ranging from minus 25 to plus 45 degrees Celsius, as well as in snow, ice rain or in blazing sun.
Two ICE 4 trains will enter passenger service in the fall of 2016 as part of a twelve-month period of trial operations. Until then, the trains will be subjected to rigorous testing.
Before the first passengers board the train, however, the ICE 4 has to prove that it can operate even under the most extreme weather conditions, in blazing heat as well as freezing cold.
The tests, conducted at the Climatic Wind Tunnel operated by Rail Tec Arsenal (RTA) in Vienna, subject the train to conditions far more stringent than required by European norms.
Deutsche Bahn commissioned supplementary tests that are specifically designed to ensure that the train's heating, ventilation and air conditioning (HVAC) operate faultlessly.
In addition, tests check if the pantograph moves up and down and functions in ice and snow, if the windscreen wiper keeps the driver's vision free, if the doors open and close smoothly, the folding steps function and the toilets operate without problems.
In May 2011, Deutsche Bahn awarded Siemens a frame contract for up to 300 multiple-unit trains. The first series production trains will enter passenger service with the change of the timetable in December 2017. The trains are initially foreseen for service in Germany, Austria and Switzerland.

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....

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...
