Plants, too, have ways to manage freeloaders

... evolved between organisms, ranging from one-sided parasitism to mutualism, a situation in which both parties benefit.

Does natural selection drive the evolution of cancer?

...ones that survive and reproduce. An example of parasitism in the tumor environment can be seen in angiogenesis, in which a subset of tumor cells send chemical signals to stimulate the host to generate new blood vessels to supply the tumor with nutrients. The neighboring cells that aren't investing resources...

Taken together, these findings suggest that male-biased mortality occurs not only as a result of death through risky...
