Genome editing-based therapies typically aim to treat disease by correcting underlying genetic mutations in patient's cells.

Most lethal mutations in wild fruit flies are driven by newly transferred jumping genes, not small DNA errors, according to a new study from Duke University. The findings, published in PLOS Biology, ...

Koalas suffered a massive population decline that left them with dangerously low genetic diversity. However, new genomic research suggests their rapid rebound may be helping reverse some of that ...

In Lake Malawi, hundreds of species of cichlid fish have evolved with astonishing speed, offering scientists a rare opportunity to study how biodiversity arises.

When DNA breaks, cells must repair it accurately to prevent harmful mutations. Researchers have discovered that during a key repair process called homologous recombination, the cell uses loops in its ...

When an Amazon molly says she doesn't need a man, believe her. Every single one of these small fish, found in freshwater streams in Mexico and Southern Texas, is female, and reproduces exclusively ...

A resurrected ancient enzyme is helping scientists test how reliably Earth’s oldest rocks record signs of life.
