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.
By swapping ancient genes into modern E. coli, scientists hope to tease out the rules of evolution.
Modern birds emerged in a snap of evolutionary time through a series of simple genetic changes.
The largest evolutionary tree ever compiled leads researchers to conclude that chance mutation — not natural selection — drives the development of new species.
Life’s first epoch saw incredible advances — cells, metabolism and DNA, to name a few. Researchers are resurrecting ancient proteins to illuminate the biological dark ages.
