Chinese scientist who published Covid-19 virus sequence allowed back in his lab after sit-in protest

Zhang had been staging a sit-in protest outside his lab since the weekend after he and his team were suddenly notified they had to leave their lab, a sign of Beijing's continuing pressure on scientists conducting research on the coronavirus. The Shanghai Public Health Clinical Center previously said Zhang's lab was being renovated and was closed for safety reasons. But Zhang said his team wasn't offered an alternative until after the eviction and the new lab didn't meet safety standards for conducting their research.
