Learn how the Amazon molly, an all-female fish that reproduces asexually, uses gene conversion to maintain healthy DNA and ...

Even back then, scientists were puzzled. Many prediction models suggested this fish shouldn’t survive beyond roughly 10,000 ...

Repeated cloning from a single mouse failed after 58 generations. Researchers say harmful DNA changes are to blame.

Countless scientists and at least a dozen high-concept sci-fi comedies over the past 30 years have speculated on the ...

As the generations dragged on past the 27th iteration, the birth rate began to silently collapse. By the 57th generation, a mere 0.6 percent of the cloned embryos survived. The 58th generation ...

A two-decade study into cloning has revealed a fundamental flaw in the technology, demonstrating that repeated duplication leads to an accumulation of fatal genetic mutations. Researchers in Japan ...

A two-decade study on serially cloned mice revealed that repeated cloning causes grave genetic mutations to accumulate, eventually leading to fatal consequences. The research challenges the notion of ...

Meet Zhong Zhong and Hua Hua, two cloned macaque monkeys. Chinese scientists first unveiled these monkeys several weeks ago, marking the first time primates have been successfully cloned with the same ...

The favored form of compromise prohibits “reproductive” cloning while allowing “therapeutic” cloning to continue unabated. But a ban solely on reproductive uses only looks like a compromise. It’s ...

The cloning era began when Dolly the sheep was manufactured in 1996. Dolly was cloned via somatic cell nuclear transfer (SCNT). This is accomplished by removing the nucleus from a skin or other cell ...
