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.

At the LASYS 2018, from June 5th to 7th, the Laser Zentrum Hannover e.V. (LZH) will be showcasing processes for the laser material processing of tomorrow in hall 4 at stand 4E75. With blown bomb shells the LZH will present first results of a research project on civil security.
At this year's LASYS, the LZH will exhibit light-based processes such as cutting, welding, ablation and structuring as well as additive manufacturing for...
There are videos on the internet that can make one marvel at technology. For example, a smartphone is casually bent around the arm or a thin-film display is rolled in all directions and with almost every diameter. From the user's point of view, this looks fantastic. From a professional point of view, however, the question arises: Is that already possible?
At Display Week 2018, scientists from the Fraunhofer Institute for Applied Polymer Research IAP will be demonstrating today’s technological possibilities and...
So-called quantum many-body scars allow quantum systems to stay out of equilibrium much longer, explaining experiment | Study published in Nature Physics
Recently, researchers from Harvard and MIT succeeded in trapping a record 53 atoms and individually controlling their quantum state, realizing what is called a...
The historic first detection of gravitational waves from colliding black holes far outside our galaxy opened a new window to understanding the universe. A...
A team led by Austrian experimental physicist Rainer Blatt has succeeded in characterizing the quantum entanglement of two spatially separated atoms by observing their light emission. This fundamental demonstration could lead to the development of highly sensitive optical gradiometers for the precise measurement of the gravitational field or the earth's magnetic field.
The age of quantum technology has long been heralded. Decades of research into the quantum world have led to the development of methods that make it possible...
