This is what a pilot study, conducted by researchers at the University of Gothenburg, will try to establish, with the help of SEK 20 million from the Swedish National Environmental Protection Agency (Naturvårdsverket) and the Swedish Research Council Formas.
The Baltic Sea is actually characterised by a high phosphate content and by a considerable algal bloom during the summer. But it has not always been like that.
During the 1990s the phosphorus content in the Baltic fell by a third, a reduction which coincided with a marked thermocline which increased the oxygen content down to a depth of 120 m. These circumstances show that it should be possible to bring about a rapid reduction in the eutrophication symptoms in the Baltic proper, by adding water that is rich in oxygen in an artificial way and mixing the bodies of water intensively.
"We are going to investigate how you succeed in retaining the phosphorus in the bottom sediment under different external circumstances, with and without artificial oxygenation, in two coastal basins. Among other things we will be using the prototype of a wind-driven pump, but we will also investigate how a full-scale pump system in the Baltic proper might be designed," says project director Anders Stigebrandt, Professor at the Department of Earth Sciences at the University of Gothenburg.Contact:

Researchers from TU Graz and their industry partners have unveiled a world first: the prototype of a robot-controlled, high-speed combined charging system (CCS) for electric vehicles that enables series charging of cars in various parking positions.
Global demand for electric vehicles is forecast to rise sharply: by 2025, the number of new vehicle registrations is expected to reach 25 million per year....
Proteins must be folded correctly to fulfill their molecular functions in cells. Molecular assistants called chaperones help proteins exploit their inbuilt folding potential and reach the correct three-dimensional structure. Researchers at the Max Planck Institute of Biochemistry (MPIB) have demonstrated that actin, the most abundant protein in higher developed cells, does not have the inbuilt potential to fold and instead requires special assistance to fold into its active state. The chaperone TRiC uses a previously undescribed mechanism to perform actin folding. The study was recently published in the journal Cell.
Actin is the most abundant protein in highly developed cells and has diverse functions in processes like cell stabilization, cell division and muscle...
