Read moreTables turn as nature imitates art
There are examples of art imitating nature all around us - the human conception of natural phenomena dazzles but does not often surprise. Yet when a researcher peered under the electron microscope last fall, she discovered the exact opposite. Instead of art imitating nature, she found nature imitating art.

Read moreHow do silver nanoparticles impact the composting of municipal solid waste?
A new study evaluates the impact of polyvinylpyrrolidone coated silver nanoparticles on the composting of municipal solid waste. The findings suggest that at relatively low concentrations, the organically rich waste management systems' functionality may not be influenced by the presence of silver nanoparticles.
