Remember Dolly? The first monkeys were just cloned the same way

Scientists at China's Institute of Neuroscience today announced the birth of two macaque clones. The monkeys aren't the first primates to be cloned, but they are the first to be created using a technique — the same that produced Dolly the sheep — that allows researchers to create a larger number of clones than other methods.

Why it matters: Genetically identical animals can be used to study the precise effect of a drug or a gene being altered through disease or editing. So far, researchers have struggled to come up with a way to clone close primate relatives of humans for research.
