In February, as the new coronavirus swept across China and shut down entire cities, a scientist named Sai Li set out to paint its portrait.
At the time, the best pictures anyone had managed to take were low-resolution images, in which the virus looked like a barely discernible smudge.
Dr. Li, a structural biologist at Tsinghua University in Beijing, joined forces with virologists who were rearing the virus in a biosafety lab in the city of Hangzhou. Those researchers doused the viruses with chemicals to render them harmless and then sent them to Dr. Li.
