A long-dry riverbed in northeastern Ohio is preventing a pool of chemical waste from infiltrating the Ohio River, geologists have found.
The finding may call into question the need to clean up similar chemical waste sites. It also indicates a previously unknown interaction between an underground aquifer and the nearby Ohio River. Beneath sand and gravel on the grounds of Barium and Chemical Inc. in Steubenville, OH, lies an aquifer that contains chemicals such as nitrate and barium that the company dumped there when such dumping was still legal, before the 1980s. The company is now working with the United States Environmental Protection Agency to clean up the site, so that the chemicals wont enter the Ohio River -- which provides water to many local towns.
In 1992, the company asked Kevin Svitana, then an independent hydrology consultant, to study the site and determine how the cleanup should proceed. The site proved unusual, in that chemicals in the underground pool didnt flow into the river as he had expected. Ever since, Svitana has tried to figure out why. He continued monitoring the pools strange behavior after becoming a doctoral student in geological sciences at Ohio State University in 2002.

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...

For the first time, an interdisciplinary team from the University of Basel has succeeded in integrating artificial organelles into the cells of live zebrafish embryos. This innovative approach using artificial organelles as cellular implants offers new potential in treating a range of diseases, as the authors report in an article published in Nature Communications.
In the cells of higher organisms, organelles such as the nucleus or mitochondria perform a range of complex functions necessary for life. In the networks of...
