Faced with demographic collapse in her home country, the Chinese expert is conducting experiments on stem cells and human ...

In 2021, scientists grew human stem cells in a monkey embryo, creating a human-ape hybrid. Is this mad science? Is it immoral ...

Gleaning stem cells from cloned monkey embryos, as a team of Oregon researchers has done, is an impressive step. But it probably won't lead to medical treatments anytime soon. One hurdle is ethical ...

NEW YORK -- Scientists in Oregon say they've reached the long-sought goal of cloning monkey embryos and extracting stem cells from them, a potentially major step toward doing the same thing in people.

NEW YORK -- For the first time, researchers have used the cloning technique that produced Dolly the sheep to create healthy monkeys, bringing science an important step closer to being able to do the ...

COVID-19 continued to dominate lives in 2021. But the year also produced many stunning science images unrelated to the pandemic. From human–monkey embryos to volcanic ash, here are the most striking ...

Early human development is a complex, multistep process that’s even more complicated to study in the lab. Models made from stem cells avoid some of the trouble with using real human embryos. In June, ...

Researchers have produced two monkeys with a procedure similar to that used to clone a sheep in Scotland, a development expected to help research into AIDS, alcoholism, depression and other illnesses.
