The study could pave the way for transplanting porcine organs to humans without the risk of reigniting endogenous retroviruses.

Plants have so much to teach us.

An anti-transposon pathway previously thought to function only in reproductive tissue also helps reduce harmful mutations in body cells of fruit flies.

A transposon underlies this classic story of evolutionary adaptation.

Panoramix, a newly identified transcription repressor, takes the bounce out of jumping genes.

These mobile genetic elements can wreak havoc on the genome. Researchers are now trying to understand how such activity contributes to the aging process.

A mass migration of mobile regulatory elements increased the expression of thousands of genes in the uterus during the evolution of pregnancy.

Regulation of genome expression orchestrates the behavior of insect castes and the human response to social stress.
