"The guess is that both the water and the dark material, which we think is organic-rich material, were delivered by the same objects impacting Mercury: some mixture of comets and the kinds of asteroids that are rich in organic and volatile material like water ice, " Prof Solomon said.
This finding ties in with the revelation of hydrogen on Vesta, because the likeliest explanation for the indentations on the surface is that hydrogen, which is likely bound up in minerals there, is released in the form of water vapor when the material is heated up by impacts.
Laboratory tests of water samples in New Orleans found it loaded with fecal material.
These new techniques give scientists and engineers the tools to explore the role of colloidal and small particulate material in natural waters and in water treatment processes.
The researchers were able to make every droplet of oil or water placed on the material to run or stop in its tracks (a response which the team describes as "pinning"), simply by flexing the material or letting it relax.
Bar: fully or partially submerged mound of sand, gravel or other unconsolidated material built on the sea-bottom in shallow water by waves and currents.
In these areas, the water appears to be covered by a dark material that the researchers suspect might be complex organic molecules.
Once frozen, the material was placed in a freeze-dryer that removed all the water from it over the course of four days.
ECONOMIST: An old idea may help solve the problem of plastic waste
Filter material: layer of fine gravel used in slope stabilization structures that allows water to escape and retains soil particles.
Montana's Department of Environmental Quality and the U.S. Environmental Protection Agency are in negotiations with Blixseth over alleged violations of the Clean Water Act, including the discharge of waste without a permit and the deposit of fill material in wetlands.
