Endosymbiotic relationships—in which one organism lives within another—are striking examples of mutualism, and can often significantly shape the biology of the participant species. In new findings ...

In recent decades, the interdisciplinary field of life sciences has made enormous progress, particularly in researching the molecular architecture of life. For example, extensive details of the ...

Sexual reproduction is costly to those organisms that depend on it, like humans. For starters, only half of the population can bear offspring and the other half has to work hard to make sure they're ...

Generating offspring is the evolutionary goal of all living organisms. The multiplication of individual cells is coordinated by the cell cycle. Researchers have now identified the central switch for ...
