Shipworm has spread to the Baltic Sea. If it continues to spread, it threatens to destroy still well-preserved and irreplaceable shipwrecks and other marine archeological remains along the coast of Sweden, according to Carl Olof Cederlund, professor of marine archeology at Södertörn University College in Stockholm and the Swedish representative in the EU project that has now determined the spread of shipworm to the Baltic for the first time.
“Up till now the Baltic has been regarded as a haven against shipworm. This is one of the reasons why it was possible to find the royal warship Wasa and other large wooden vessels in such excellent condition after centuries at the bottom of the sea,” adds Carl Olof Cederlund.
The EU project has been carried out by six countries and is now presenting its results regarding the protection and preservation of underwater cultural environments, primarily well-preserved shipwrecks in northern Europe. One of the wrecks is the Dutch snaubrigg Vrouw Maria, which sank in the Finnish archipelago in 1771. It is still fully preserved, with its rigging intact. It has not been attacked by shipworm, which, on the other hand, is the case with a kogg from the 13th century off the German Baltic coast. German scientists involved in the project have been able to show that the wreck evinces extensive damage from shipworm, Teredo Navalis.

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.
