Scientists discover how some viruses take strong hold of cells
...lecules with double binding sites would be able to compete and interfere with the virus' attack. The current work may also help scientists interested in developing viruses used in gene therapy. The idea behind gene therapy is to destroy a virus disease-causing genes and replace them with therapeutic genes --...Researchers put their heads together to understand complex world of wild plants and animals

Cod, haddock, shark, and skates compete for mackerel, herring, and sandlance.

That is, cells have to compete for trophic signals in order to survive. "This 'social control' theory of cell survival explains why no one cell type outnumbers another," says Steller.
