By burning fossil fuels, humans release carbon dioxide into the atmosphere. Carbon dioxide is then absorbed by the oceans where it reacts with water to form carbonic acid. The more acidic the water becomes, the lesser will be the amount of free carbonate ions. Carbonate is an essential component of the calcium carbonate structures built by many organisms such as corals, clams, snails or calcareous algae.

How organisms react to ocean acidification is currently one of the hottest topics in marine ecology and biogeochemistry. More specifically, marine scientists are trying to understand what is the combined effect on marine life of different disturbing factors like warming, eutrophication and ocean acidification. Coral reefs seem to be particularly sensitive to ocean acidification, with worse predictions suggesting that coral reef ecosystems may disappear by the end of this century.
Given the growing concerns, ocean acidification is rapidly becoming a topic of large-scale research projects. In Germany, for example, a national initiative for a coordinated project entitled “Biological Impacts of Ocean ACIDification" (BIOACID) has been financially supported by the German Ministry of Education and Research (BMBF). BIOACID is closely coordinated with the European Project on OCean Acidification (EPOCA) funded as part of the 7th EU Framework Programme. Some ZMT scientists are actively contributing to the EPOCA research efforts. In addition, ZMT ecologists, geologists, socioeconomists and modellers are developing multidisciplinary cooperative projects on the topic.
The symposium will be an exciting opportunity to hear about the current state of acidification research and to discuss the relevance of the problems to tropical marine ecosystems.

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“.
Galaxy clusters are the largest gravitationally bound structures in the universe. With a typical extent of about 10 million light years, i.e. 100 times the...
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.
