A man passes by the deserted campus of Huazhong University of Science and Technology in Wuhan. Most other universities in China are closed as well.

Normal daily life has come to a virtual standstill in large parts of China as a result of the epidemic of COVID-19—and so has science. Universities across the country remain closed; access to labs is restricted, projects have been mothballed, field work interrupted, and travel severely curtailed. But scientists elsewhere in the world are noticing an impact as well, as collaborations with China are on pause and scientific meetings for the next five months have been canceled or postponed.
