SEATTLE – For Bacillus anthracis, the bacterium that causes anthrax, nothing beats the inside of a warm human or animal host for triggering an intense spurt of rapid growth and reproductive activity.

Life on Earth possesses an exceptional ability to self-reproduce, which, even on a simple cellular level, is driven by complex biochemistry. But can self-reproduction exist in a biochemistry-free ...

Researchers have discovered an ancient plant species whose reproductive biology captures the evolution from one to two spore sizes -- an essential transition to the success of the seed and flowering ...

In biology, a spore is a reproductive structure, some of which are adapted for dispersal and surviving for extended periods of time in unfavorable conditions. The spores of seed plants, however, are ...

To distinguish between these two models, we devised three approaches. First, we investigated maintenance of genetic variation in an AM fungus from one generation to the next during clonal reproduction ...
