A team of Michigan and Canadian researchers has found that over the past half-century, the rocks of Earth's continental crust have warmed significantly, similar to the warming of the oceans, atmosphere and ice reported by other investigators last year.

Social insects could offer clues about genetic conflict
Two Rice University biologists believe social insects like ants and bees could provide clues to why some animals have developed a curious quality in which the genes of their parents vie in direct competition.
