Many species of birds and other vertebrates form pair bonds and mate with just one other individual for much of their lives. But the unions don’t always work out. Scientists want to know the underlying factors.
Molecules, cells, or vertebrates—when individuals move and act as a single unit, surprisingly complex behaviors arise that hint at the origins of multicellularity.

Columbia University evolutionary ecologist Dustin Rubenstein explains just why it's so interesting and important to find slime molds that engage in a form of agriculture.
A bacterium’s ability to distinguish self from non-self can arise spontaneously, a study shows, reigniting questions of whether the trait can be considered an adaptation.
