At the behest of the Norwegian Pollution Control Authority SFT), a 20-year long study of ecotoxins in seabird eggs has been carried out by the Norwegian Polar Institute in collaboration with Tromsø Museum (of the University of Tromsø), the Norwegian School of Veterinary Science and the National Veterinary Institute of Norway.
Eggs from herring gulls (Larus argentatus), glaucus gulls (L. hyperboreus), black-legged kittiwakes (Rissa tridactyla) and puffins (Fratercula arctica), collected from various locations in northern Norway and Svalbard, have been analysed to determine their levels of contaminants such as brominated flame retardants and mercury.
The research shows that the concentration of brominated flame retardants has risen since 1983 and that these toxins have spread far from their original sources. The flame retardant HBCDD has had a particularly marked increase during the last 20 years. In addition, prohibited flame retardants such as okta-BDE have increased throughout the 20 year period.

The Institute of Semiconductor Technology and the Institute of Physical and Theoretical Chemistry, both members of the Laboratory for Emerging Nanometrology (LENA), at Technische Universität Braunschweig are partners in a new European research project entitled ChipScope, which aims to develop a completely new and extremely small optical microscope capable of observing the interior of living cells in real time. A consortium of 7 partners from 5 countries will tackle this issue with very ambitious objectives during a four-year research program.
To demonstrate the usefulness of this new scientific tool, at the end of the project the developed chip-sized microscope will be used to observe in real-time...
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.
