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 ...

Why jumping genes don't send us into meltdown

A team of researchers, led by academics at The University of Nottingham, has explained why the so-called 'jumping genes' found in most living organisms don't ultimately kill off their hosts, putting an end to a long-standing ...

Pack rat nests offer first look at ancient insect DNA

For many years, scientists have been extracting DNA from the bones of ancient humans, humanoids and animals to paint a picture of evolution and species movement. Despite what's been portrayed in the movie "Jurassic Park"—in ...

DNA reveals the evolutionary history of museum specimens

Museum specimens held in natural history collections around the world represent a wealth of underutilized genetic information due to the poor state of preservation of the DNA, which often makes it difficult to sequence. An ...
