Virginia Techs Freshwater Mussel Conservation Center and Virginias Aquatic Wildlife Conservation Center in Marion, Va., released several thousand mussels that have been propagated into the Clinch River. Partners in this replenishing project include the Virginia Department of Game and Inland Fisheries (VDGIF), the U.S. Fish and Wildlife Service, and the Town of Cedar Bluff, where the restocking took place. The site along Rt. 460 is owned by The Nature Conservancy.
Dick Neves, fisheries professor and director of Virginia Techs mussel center, said that 1,000 endangered purple bean juvenile mussels, produced by VDGIFs Buller Hatchery, were released, as well as juvenile and adult mussels of three to six species that arent endangered but had been the filtration workhorses of the Clinch River before the 1998 toxic spill that killed most aquatic life on that stretch of the river. Also released were the adults of the fluted kidney shell mussel, which is a federal candidate for the endangered list, and stocking adults of rabbitsfoot mussels, which are endangered.
Why are mussels so important? Mussels are key indicators for water quality. They help clean the water by filtering and providing food for fish and other river animals. Virginia Tech was the pioneer in developing the propagation technology now successfully being used across the nation to restore mussel populations.

Satellites in near-Earth orbit are at risk due to the steady increase in space debris. But their mission in the areas of telecommunications, navigation or weather forecasts is essential for society. Fraunhofer FHR therefore develops radar-based systems which allow the detection, tracking and cataloging of even the smallest particles of debris. Satellite operators who have access to our data are in a better position to plan evasive maneuvers and prevent destructive collisions. From April, 25-29 2018, Fraunhofer FHR and its partners will exhibit the complementary radar systems TIRA and GESTRA as well as the latest radar techniques for space observation across three stands at the ILA Berlin.
The "traffic situation" in space is very tense: the Earth is currently being orbited not only by countless satellites but also by a large volume of space...
An international team of researchers has discovered a new anti-cancer protein. The protein, called LHPP, prevents the uncontrolled proliferation of cancer cells in the liver. The researchers led by Prof. Michael N. Hall from the Biozentrum, University of Basel, report in “Nature” that LHPP can also serve as a biomarker for the diagnosis and prognosis of liver cancer.
The incidence of liver cancer, also known as hepatocellular carcinoma, is steadily increasing. In the last twenty years, the number of cases has almost doubled...
In just a few weeks from now, the Chinese space station Tiangong-1 will re-enter the Earth's atmosphere where it will to a large extent burn up. It is possible that some debris will reach the Earth's surface. Tiangong-1 is orbiting the Earth uncontrolled at a speed of approx. 29,000 km/h.Currently the prognosis relating to the time of impact currently lies within a window of several days. The scientists at Fraunhofer FHR have already been monitoring Tiangong-1 for a number of weeks with their TIRA system, one of the most powerful space observation radars in the world, with a view to supporting the German Space Situational Awareness Center and the ESA with their re-entry forecasts.
Following the loss of radio contact with Tiangong-1 in 2016 and due to the low orbital height, it is now inevitable that the Chinese space station will...
