Looking at a real infection within real tissue is a big advance says mark ladinsky an electron microscope scientist at caltech and lead author of the paper.

With something like hiv it s usually very difficult and dangerous to do because the virus is an infectious agent. It requires an electron microscope which means very few people have actually seen one. But the pathogens that cause many potentially deadly infections turn out to be absolutely beautiful when viewed under powerful microscopes.
