Argonne National Laboratory has asked visitors not to come, although its Advanced Photon Source, which could help decipher the structure of coronavirus proteins, will most likely keep running.

Sotto voce, the U.S. Department of Energy (DOE) has begun to restrict access and ramp down activities at its national laboratories in response to the coronavirus crisis. However, no unified protocol has emerged that applies to all labs, which every year serve more than 30,000 visiting researchers. It seems likely that some of DOE’s major research facilities will solider on—as they may prove helpful in the fight against the new virus.
