What can be more deadly than a laser weapons and plasma weapons?

Prions...airborne they could wipe out all of humankind, but for a few who might be immune.

"Prion: A small proteinaceous infectious disease-causing agent that is believed to be the smallest infectious particle. A prion is neither bacterial nor fungal nor viral and contains no genetic material. Prions have been held responsible for a number of degenerative brain diseases, including mad cow disease, Creutzfeldt-Jakob disease, fatal familial insomnia, kuru, and an unusual form of hereditary dementia known as Gertsmann-Straeussler-Scheinker disease."[http://www.medicinenet.com/script/main/art.asp?articlekey=5047]

There is no known cure for the degenerative diseases caused by these smaller than viral pathogens. And they cannot be killed.

We are fortunate to date that they are not transmitted through the air. But one little mutation....it could be all over.

Nuclear weapons?
