An anonymous reader writes "Scientists at the UK's national synchrotron facility are studying the structure of Containment Level 3 pathogens such as Aids, Flu and Hepatitis. They use high intensity X-Rays to study the atomic and molecular structure of pathogens too small to be examined under a microscope. This leads to a greater understanding of how they work. They have already produced results on the hand, foot and mouth virus. This is the first time Level 3 pathogens have been imaged in this way."
