Genetic 'fossils' reveal long-term viral partnerships in grass

Defective viruses incorporated into grass genomes may adapt to form partnerships with other genome-incorporated viruses in order to complete their life cycle, according to a new PLOS Pathogens study. The findings suggest ...

Our wine owes a debt to ancient viruses

Next time you pour a glass of wine, raise a toast to the 30-milion-year-old viruses that have contributed to the genetic make-up of modern grapes.
