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.

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...
