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.

On the way to an intelligent laboratory, physicists from Innsbruck and Vienna present an artificial agent that autonomously designs quantum experiments. In initial experiments, the system has independently (re)discovered experimental techniques that are nowadays standard in modern quantum optical laboratories. This shows how machines could play a more creative role in research in the future.
We carry smartphones in our pockets, the streets are dotted with semi-autonomous cars, but in the research laboratory experiments are still being designed by...
What enables electrons to be transferred swiftly, for example during photosynthesis? An interdisciplinary team of researchers has worked out the details of how...
For the first time, scientists have precisely measured the effective electrical charge of a single molecule in solution. This fundamental insight of an SNSF Professor could also pave the way for future medical diagnostics.
Electrical charge is one of the key properties that allows molecules to interact. Life itself depends on this phenomenon: many biological processes involve...
At the JEC World Composite Show in Paris in March 2018, the Fraunhofer Institute for Laser Technology ILT will be focusing on the latest trends and innovations in laser machining of composites. Among other things, researchers at the booth shared with the Aachen Center for Integrative Lightweight Production (AZL) will demonstrate how lasers can be used for joining, structuring, cutting and drilling composite materials.
No other industry has attracted as much public attention to composite materials as the automotive industry, which along with the aerospace industry is a driver...
Scientists at Tokyo Institute of Technology (Tokyo Tech) and Tohoku University have developed high-quality GFO epitaxial films and systematically investigated their ferroelectric and ferromagnetic properties. They also demonstrated the room-temperature magnetocapacitance effects of these GFO thin films.
Multiferroic materials show magnetically driven ferroelectricity. They are attracting increasing attention because of their fascinating properties such as...
