Scientists in China, experimenting with a coronavirus closely related to the virus that causes COVID-19, found that it had a 100 percent kill rate in a small mouse study, according to the researchers’ announcement on Jan. 4.

The scientists, including a doctor trained by the Chinese military, cloned a pangolin coronavirus and infected modified mice to “assess its pathogenicity,” they said in a preprint paper published on bioRxiv.
