This forecasting system is scheduled to be ready in time for the Olympic Games in China in August 2008. Although it will initially benefit the sailing competitions held in the Yellow Sea, the system will later be of assistance to local fishermen and merchant fleets.
“Our colleagues in China and Korea will supply measurement data on things such as the depth of the sea, the amount of water flowing in from rivers and all available information on weather, water and sea conditions,” says coastal researcher Dr. Heinz Günther from GKSS in Geesthacht by way of explaining the work that lies ahead. “The existing measurement network, which consists of buoys and measurement platforms, will be expanded further in the coming months. At the same time, we will be combining the weather and sea modelling systems of all of the participating researchers and adapting them to the conditions found in the Yellow Sea.”
By adding a component for suspended particles, the experts from Geesthacht have expanded the mathematical model’s capabilities beyond those of systems designed merely to forecast winds, waves and currents. That’s because suspended particles are mainly composed of inorganic sediment that is transported into the sea by rivers, for example. These particles determine how much and how far light can penetrate the water. This, in turn, influences the growth of plankton and water plants, which serve as the basic nourishment for many species of fish and shrimp. In addition, these particles can also contain toxic materials from agriculture and industry. As a result, predicting how suspended particles will be distributed in the sea and along the coasts can be of great help in protecting the environment and managing crises such as accidental toxic spills. “Our existing three-dimensional models for the North Sea and the Baltic Sea can calculate the influx of suspended particles following storms and floods in advance,” says GKSS researcher Gerhard Gayer, who incorporated the Geesthacht computer model into the basic Danish system.
“The colleagues from China and Korea are incredibly skilled and we are benefiting a lot from their measurement systems and computer models,” adds Günther. “Although the Olympics will serve as a milestone for the EU’s YEOS project, our contribution of a suspended particle calculation component will introduce our colleagues in Asia to the world of ecosystem modelling. We think this is very important, since it will allow them to increasingly take environmental aspects into account when monitoring the Yellow Sea.”

Plants and algae use the enzyme Rubisco to fix carbon dioxide, removing it from the atmosphere and converting it into biomass. Algae have figured out a way to increase the efficiency of carbon fixation. They gather most of their Rubisco into a ball-shaped microcompartment called the pyrenoid, which they flood with a high local concentration of carbon dioxide. A team of scientists at Princeton University, the Carnegie Institution for Science, Stanford University and the Max Plank Institute of Biochemistry have unravelled the mysteries of how the pyrenoid is assembled. These insights can help to engineer crops that remove more carbon dioxide from the atmosphere while producing more food.

Our brains house extremely complex neuronal circuits, whose detailed structures are still largely unknown. This is especially true for the so-called cerebral cortex of mammals, where among other things vision, thoughts or spatial orientation are being computed. Here the rules by which nerve cells are connected to each other are only partly understood. A team of scientists around Moritz Helmstaedter at the Frankfiurt Max Planck Institute for Brain Research and Helene Schmidt (Humboldt University in Berlin) have now discovered a surprisingly precise nerve cell connectivity pattern in the part of the cerebral cortex that is responsible for orienting the individual animal or human in space.
The researchers report online in Nature (Schmidt et al., 2017. Axonal synapse sorting in medial entorhinal cortex, DOI: 10.1038/nature24005) that synapses in...

Using ultrafast flashes of laser and x-ray radiation, scientists at the Max Planck Institute of Quantum Optics (Garching, Germany) took snapshots of the briefest electron motion inside a solid material to date. The electron motion lasted only 750 billionths of the billionth of a second before it fainted, setting a new record of human capability to capture ultrafast processes inside solids!
When x-rays shine onto solid materials or large molecules, an electron is pushed away from its original place near the nucleus of the atom, leaving a hole...
For the first time, physicists have successfully imaged spiral magnetic ordering in a multiferroic material. These materials are considered highly promising candidates for future data storage media. The researchers were able to prove their findings using unique quantum sensors that were developed at Basel University and that can analyze electromagnetic fields on the nanometer scale. The results – obtained by scientists from the University of Basel’s Department of Physics, the Swiss Nanoscience Institute, the University of Montpellier and several laboratories from University Paris-Saclay – were recently published in the journal Nature.
Multiferroics are materials that simultaneously react to electric and magnetic fields. These two properties are rarely found together, and their combined...
