DNA self-assembly used to mass-produce patterned nanostructures

... tile was made up of strands of DNA bent like pipe cleaners into the shape of a cross. In the middle of each cross was a loop of DNA that can be attached to another molecule that can in turn bind to a protein molecule to give the tile a tag visible by AFM. Each arm of the cross, about 10 nanometers long, had ...

Researchers Discover That Microbes Can Produce Miniature Electrical Wires

...nd aquatic sediments, have demonstrated promise as cleaners of toxic spills and generators of energy. They are anaerobic bacteria (living without oxygen) that use metals to gain energy the way humans and other organisms use oxygen. They are distributed throughout the world in a wide variety of soils and sedim...

Atmosphere may cleanse itself better than previously thought

...known to behave in this way ?producing natural air cleaners called OH radicals ?the chemicals the team studied have for the first time been observed to produce air-scrubbing OH radicals at low ultraviolet wavelengths. This observation has eluded science primarily because photochemistry at these wavelengths ha...
