The U.N. health agency may have decided way back in 1996 that the remaining stores of live smallpox virus--kept in facilities in Atlanta and Russia--be destroyed, but the virus has remained alive so researchers can examine it, creating vaccines and other cures. Now the U.S. has asked for the virus to stay extant for another five years for the same reason.
A microbial scale paves the way for better toxin detectors.

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.
