The Advanced
Photon Source is one of Argonne’s, and
the country’s, greatest resources. Discoveries here
vary from the fields of structural biology to nanotechnology
and earth sciences. The structure of bacteriophage HK 97
was discovered at the APS BioCARS beamline. The three-dimensional
image
showed researchers that nature uses a chain mail-like order
to protect this viral genome’s interior.
