The new study, however, showed that CNTs interact with natural organic matter, which is present in lakes and rivers, in ways that lead to wider dispersion.

CAMBRIDGE, Mass. -- Countering the widespread view of evolution as a process played out over the course of eons, evolutionary biologists have shown that natural selection can turn on a dime -- within months -- as a population's needs change.
