Whereas sampling with different kinds of equipment is normally used to collect information on bottom fauna, a specially designed video rig has allowed the scientists to film 80 kilometres of seabed during their survey off the coast of northern Norway. The seabed in the area is characterised by deep fjords and shelf areas with fishing banks and intersecting channels. Many of the habitats found here are complex and not easily documented with standard sampling gears.

Better knowledge of the ecosystem
The recent survey was conducted as part of a large-scale mapping programme. Biologists from the Institute of Marine Research, geologists from the Geological Survey of Norway, and cartographers from the Norwegian Hydrographic Service cooperate through the MAREANO programme to provide maps of topography, biodiversity and geological conditions of the seabed in Norwegian waters. Initially focusing on the Barents Sea, the first phase of MAREANO will be carried out from 2005-2010 with a total cost of € 30 million.
The importance of this seabed mapping is emphasised in the Integrated Management Plan for the Barents Sea recently presented by the Norwegian Government. Extensive plans for exploitation of oil and gas reserves in Lofoten and the Barents Sea are being considered, and a sustainable management of the area is highly dependent on improved knowledge of the Arctic ecosystems.

Staphylococcus aureus is a feared pathogen (MRSA, multi-resistant S. aureus) due to frequent resistances against many antibiotics, especially in hospital infections. Researchers at the Paul-Ehrlich-Institut have identified immunological processes that prevent a successful immune response directed against the pathogenic agent. The delivery of bacterial proteins with RNA adjuvant or messenger RNA (mRNA) into immune cells allows the re-direction of the immune response towards an active defense against S. aureus. This could be of significant importance for the development of an effective vaccine. PLOS Pathogens has published these research results online on 25 May 2017.
Staphylococcus aureus (S. aureus) is a bacterium that colonizes by far more than half of the skin and the mucosa of adults, usually without causing infections....
Physicists from the University of Würzburg are capable of generating identical looking single light particles at the push of a button. Two new studies now demonstrate the potential this method holds.
The quantum computer has fuelled the imagination of scientists for decades: It is based on fundamentally different phenomena than a conventional computer....
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...
