NASA's Curiosity rover has found pebbles that appear to have been rounded by streamflow, according to a release from University of California Davis. Experts say the finding represents the first on-site evidence of sustained flowing water on Mars.
The rounded pebbles discovered are only known to form when transported through water over long distances. Their discovery supports theories that the red planet could once have supported life.
The smooth rocks were found between the north rim of the planet’s Gale Crater and the base of Mount Sharp, a mountain inside the crater. Researchers say they chose Gale Crater for study because there was a sediment deposit there that typically requires water to form.Read More
University of Delaware scientists are studying the impacts that rising sea levels might have on marsh ecosystems in the future, the University of Delaware has reported .
Scientists predict that rising sea levels could convert marshes into intertidal flats. These conversions could drastically change land composition by stripping sediment from the land, which could alter water quality by exposing substantial quantities of sequestered carbon and pollutants.
Researchers are monitoring the fluctuations of water flow and sediment concentrations in Delaware’s Brockonbridge Marsh.Read More
Dr. Charley Liberko of Cornell College's Department of Chemistry has an idea he's working to bring to fruition.
“Imagine a remote village in an underdeveloped country whose only source of water is a stream contaminated with toxic levels of metal ions such as cadmium and nickel,” states Dr. Liberko. “The villagers take locally available woody plant material, soak it in potash, and heat it up for several days until the wood partially decomposes. They then filter their water through this material to remove the metal ions. When they are done with it, they put the material in a clay pot and heat it up even hotter until the organic matter decomposes completely, leaving the metal ion salts as a residue, safely in the clay pot.Read More
