Prof. Dr. Richard Cogdell and Prof. Dr. Jürgen Köhler will discuss with more then 100 scientists from 18 nations the latest results of the main topic of the conference: Harvesting solar energy by natural and artificial photosystems.
The total annual global energy consumption is set at least to double from its current level by 2050. However, fossil fuel will start to run out by that time and in any case this would produce unacceptable amounts of CO2 enhancing global warming. From the fact that the amount of solar energy that hits the Earth every hour corresponds to the world's annual energy consumption, it becomes clear that solar driven energy production represents a sustainable long-term solution for that problem. Hence, harnessing solar energy for energy supply becomes a major challenge for the future.
At present the only conversion technology that might offer long-term, large-scale use is photovoltaics, i.e. a technology based on inorganic solar cells manufactured in a classical top-down approach. Its natural counterpart however, photosynthesis, is based on exactly the opposite strategy - bottom-up, i.e. starting from individual molecules and combining them to supramolecular structures by self-assembly. The success of this strategy is testified by the high flexibility and robustness of this process covering a variety of scales such as size (bacteria and trees), temperature (thermal springs and Siberian tundra), and environmental conditions (variations in pH). Moreover, nature has been able to solve successfully problems like adaptation to light conditions, self-reproduction, and self-repair.
In recent years, progress in structural biology has provided detailed insights into the structure-function relationships of the molecular machinery of photosynthesis. However, in order to learn from biology how to construct systems for artificial photosynthesis a better understanding of fundamental processes like exciton transfer, charge separation, or cyclic electron flow is crucial. This asks for collaborations between biologists, biochemists, physicists, crystallographers, and others to do the research. Moreover training of students to develop the expertise at the interface of such different disciplines to carry this long term but essential research forward is one of the most important tasks for the future.
The conference "Light-Harvesting Processes LHP09" is financially supported by the Volkswagen Foundation.The process of light harvesting by antenna pigments lies at the heart of solar energy conversion. Aim of the conference is to bring together scientists from diverse fields to stimulate co-operations and to discuss options for the technological development of practical methods for the utilization of photosynthesis. The realization of the seriousness and rapidity of climate change accentuates the importance of this research for future energy supply.

Astronomers from Bonn and Tautenburg in Thuringia (Germany) used the 100-m radio telescope at Effelsberg to observe several galaxy clusters. At the edges of these large accumulations of dark matter, stellar systems (galaxies), hot gas, and charged particles, they found magnetic fields that are exceptionally ordered over distances of many million light years. This makes them the most extended magnetic fields in the universe known so far.
The results will be published on March 22 in the journal „Astronomy & Astrophysics“.

Researchers at the Goethe University Frankfurt, together with partners from the University of Tübingen in Germany and Queen Mary University as well as Francis Crick Institute from London (UK) have developed a novel technology to decipher the secret ubiquitin code.
Ubiquitin is a small protein that can be linked to other cellular proteins, thereby controlling and modulating their functions. The attachment occurs in many...

Silicon nanosheets are thin, two-dimensional layers with exceptional optoelectronic properties very similar to those of graphene. Albeit, the nanosheets are less stable. Now researchers at the Technical University of Munich (TUM) have, for the first time ever, produced a composite material combining silicon nanosheets and a polymer that is both UV-resistant and easy to process. This brings the scientists a significant step closer to industrial applications like flexible displays and photosensors.

Enzymes behave differently in a test tube compared with the molecular scrum of a living cell. Chemists from the University of Basel have now been able to simulate these confined natural conditions in artificial vesicles for the first time. As reported in the academic journal Small, the results are offering better insight into the development of nanoreactors and artificial organelles.
