The European Space Agency (ESA) has chosen the GSI accelerator facility to assess radiation risks that astronauts will be exposed to on a Mars mission. GSI was selected because its accelerator is the only one in Europe able to create ion beams similar to those found in space. To determine possible health risks of manned space flights, scientists from all over Europe have been asked to investigate the effects of ion beams in human cells and organs. The first experiments will be launched this year and subsequently continued at GSI’s planned FAIR accelerator system.
Astronauts flying to the moon or Mars would be constantly bombarded by cosmic rays, whose health risks are not known in detail. Unlike the situation in space, the earth’s surface is largely shielded from cosmic rays by the planet’s atmosphere and magnetic field. In general, radiation can damage human cells and their genetic material. In addition to causing cancer, it can directly kill cells, which can later result in extensive damage in tissues including the brain.
The aim of the planned research activities is to quantitatively examine the biological effects of ion beams on the human genome and to determine how these effects would manifest themselves over time. For these tests, scientists will irradiate molecules and cell and tissue samples. The results of the research could then be used to develop optimized radiation shields for space exploration, which are a prerequisite for conducting safe missions to Mars.
The ion beams found in space have a wide variety of sources and can be derived from all types of elements, ranging from the lightest, hydrogen, to the heaviest, uranium. GSI’s accelerator facility can generate all types of ion beams, making it particularly well-suited for the planned research project. The research possibilities will be greatly expanded in the future by the FAIR accelerator facility, which will be able to produce even more energetic and intense ion beams.
Scientists are invited by ESA to submit proposals for experiments at GSI. The internationally leading scientists on the Biophysics & Radio-Biology Program Advisory Committee will begin reviewing initial applications in May, and the first experiments could be conducted as early as the end of this year.

Flexible, organic and printed electronics conquer everyday life. The forecasts for growth promise increasing markets and opportunities for the industry. In Europe, top institutions and companies are engaged in research and further development of these technologies for tomorrow's markets and applications. However, access by SMEs is difficult. The European project SmartEEs - Smart Emerging Electronics Servicing works on the establishment of a European innovation network, which supports both the access to competences as well as the support of the enterprises with the assumption of innovations and the progress up to the commercialization.
It surrounds us and almost unconsciously accompanies us through everyday life - printed electronics. It starts with smart labels or RFID tags in clothing, we...
The human eye is particularly sensitive to green, but less sensitive to blue and red. Chemists led by Hubert Huppertz at the University of Innsbruck have now developed a new red phosphor whose light is well perceived by the eye. This increases the light yield of white LEDs by around one sixth, which can significantly improve the energy efficiency of lighting systems.
Light emitting diodes or LEDs are only able to produce light of a certain colour. However, white light can be created using different colour mixing processes.
Researchers led by Francesca Ferlaino from the University of Innsbruck and the Austrian Academy of Sciences report in Physical Review X on the observation of supersolid behavior in dipolar quantum gases of erbium and dysprosium. In the dysprosium gas these properties are unprecedentedly long-lived. This sets the stage for future investigations into the nature of this exotic phase of matter.
Supersolidity is a paradoxical state where the matter is both crystallized and superfluid. Predicted 50 years ago, such a counter-intuitive phase, featuring...

A localization phenomenon boosts the accuracy of solving quantum many-body problems with quantum computers which are otherwise challenging for conventional computers. This brings such digital quantum simulation within reach on quantum devices available today.
Quantum computers promise to solve certain computational problems exponentially faster than any classical machine. “A particularly promising application is the...
