Now in 3-D: Video of virus-sized particle trying to enter cell

Tiny and swift, viruses are hard to capture on video. Now researchers have achieved an unprecedented look at a virus-like particle as it tries to break into and infect a cell. The technique they developed could help scientists learn more about how to deliver drugs via nanoparticles -- which are about the same size as viruses -- as well as how to prevent viral infection from occurring.
