'Jumping genes' find new homes in humans more often than previously thought
Transposons, or "jumping genes," make up roughly half of the human genome. Geneticists previously estimated that they replicate and insert themselves into new locations roughly one in every 20 live births.

Jumping genes discovery 'challenges current assumptions'
Jumping genes do most of their jumping, not during the development of sperm and egg cells, but during the development of the embryo itself. The research, published this month in Genes and Development, "challenges standard assump ...

Jumping gene enabled key step in corn domestication
Corn split off from its closest relative teosinte, a wild Mexican grass, about 10,000 years ago thanks to the breeding efforts of early Mexican farmers. Today it's hard to tell that the two plants were ever close kin: Corn ...

'David and Goliath' viruses shed light on the origin of jumping genes
University of British Columbia researchers have identified a small virus that attacks another virus more than 100 times its own size, rescuing the infected zooplankton from certain death. The discovery provides clues to the ...

Muscling in on a mystery protein: Study of brawny pigs reveals key player in the genome
(PhysOrg.com) -- For thousands of years, humans have bred pigs for desirable traits, such as more muscle and less fat in the meat. Domestication makes animals ideal models for studying how genes control physical ...
