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.

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...

In the race to produce a quantum computer, a number of projects are seeking a way to create quantum bits -- or qubits -- that are stable, meaning they are not much affected by changes in their environment. This normally needs highly nonlinear non-dissipative elements capable of functioning at very low temperatures.
In pursuit of this goal, researchers at EPFL's Laboratory of Photonics and Quantum Measurements LPQM (STI/SB), have investigated a nonlinear graphene-based...
