Purdue University researchers have created a scale so sensitive it can detect the ethereal weight of a single virus particle. The vaccinia virus, used to make the smallpox vaccine, checks in at 9 femtograms, or roughly one-trillionth the weight of a grain of rice. Next up: a relative of the SARS virus.
