A single genetic change and some clever geometry show how single-celled organisms can band together to form cooperative multicellular entities.
A newly discovered class of microbe could help to resolve one of the biggest and most controversial mysteries in evolution — how simple microbes transformed into the complex cells that produced animals, plants and fungi.
The biologist Nancy Moran has spent a career investigating the surprising nature of symbiosis, a phenomenon in which two species can appear to merge into one.
A new understanding of viral swarms is helping researchers predict how viruses will evolve and where disease is likely to spread.
Emerging data suggests the seemingly impossible — that mysterious new genes arise from “junk” DNA.
Did the minerals on our planet arise in a predictable fashion, or did they result from chance events? The answers could eventually help scientists identify planets likely to harbor life.
A new technique for finding and characterizing microbes has boosted the number of known bacteria by almost 50 percent, revealing a hidden world all around us.
Scientists hope that new genetic letters, created in the lab, will endow DNA with new powers.
The biologist Deborah Gordon has uncovered how ant colonies search efficiently without central organization, an insight that might improve computer networks.
