Amazon mollies don't need a man, and never will. A new study finds they can purge and repair genetic mutations that would ...

The Amazon molly reproduces without sex. A genomic copy-and-paste trick called gene conversion may explain how it avoids evolutionary meltdown.

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

Drug delivery researchers have vastly improved the potential of genetic therapies by overcoming the challenge of consistently getting genes and gene-editing tools where they need to be within cells.

Researchers simulated nearly every molecule in a bacterial cell — and then watched the cell grow and reproduce.
