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.

Researchers from the Institute for Quantum Computing (IQC) at the University of Waterloo led the development of a new extensible wiring technique capable of controlling superconducting quantum bits, representing a significant step towards to the realization of a scalable quantum computer.
"The quantum socket is a wiring method that uses three-dimensional wires based on spring-loaded pins to address individual qubits," said Jeremy Béjanin, a PhD...
In a paper in Scientific Reports, a research team at Worcester Polytechnic Institute describes a novel light-activated phenomenon that could become the basis for applications as diverse as microscopic robotic grippers and more efficient solar cells.
A research team at Worcester Polytechnic Institute (WPI) has developed a revolutionary, light-activated semiconductor nanocomposite material that can be used...
By forcefully embedding two silicon atoms in a diamond matrix, Sandia researchers have demonstrated for the first time on a single chip all the components needed to create a quantum bridge to link quantum computers together.
"People have already built small quantum computers," says Sandia researcher Ryan Camacho. "Maybe the first useful one won't be a single giant quantum computer...
COMPAMED has become the leading international marketplace for suppliers of medical manufacturing. The trade fair, which takes place every November and is co-located to MEDICA in Dusseldorf, has been steadily growing over the past years and shows that medical technology remains a rapidly growing market.
In 2016, the joint pavilion by the IVAM Microtechnology Network, the Product Market “High-tech for Medical Devices”, will be located in Hall 8a again and will...
