A Japanese research team pushed mouse cloning to its breaking point, producing 1,206 clones from a single donor line before the process collapsed at the 58th generation. The experiment, one of the ...

Colossal Biosciences is working to introduce woolly mammoth traits into Asian elephants through genetic modifications. Researchers are using ancient DNA fragments to identify relevant genetic changes ...

After 20 years, 58 generations and more than 30,000 cloning attempts, a team of researchers has hit the limit on the number of times a single mouse can be serially re-cloned. How Dolly the sheep’s ...

We’re closer to cloning the woolly mammoth back into existence than ever before: Researchers have just finished mapping the complete genome of two individuals of the lost species. “This discovery ...

Researchers have developed a yeast-based genome shuffling platform that generates infectious chimeric poxviruses from multiple parental species, yielding clones with enhanced oncolytic potency and ...
