To Defend the Genome, These Cells Destroy Their Own DNA
Under a microscope, cells in a worm embryo deliberately eliminated one-third of their genome — an uncompromising tactic that may combat harmful genetic parasites.
Selfish, Virus-Like DNA Can Carry Genes Between Species
Genetic elements called Mavericks that have some viral features could be responsible for the large-scale smuggling of DNA between species.
A Mutation Turned Ants Into Parasites in One Generation
A new genetics study of ant “social parasites” shows how complex sets of features can emerge rapidly and potentially split species.
She Tracks the DNA of Elusive Species That Hide in Harsh Places
On Mount Everest and in the Peruvian Andes, Tracie Seimon uses DNA to study how species and ecosystems respond to climate change, pathogens and other influences.
How Genes Can Leap From Snakes to Frogs in Madagascar
The discovery of a hot spot for horizontal gene transfer draws attention to the possible roles of parasites and ecology in such changes.
