The New Scientist reports that, "Quantum weirdness could soon invade the living world, if a scheme to give a flu virus a strange double life comes off."
In short, in quantum theory, a single object can be doing two different things at once. This is called "superposition". The largest objects that have been superposed so far are molecules. But Oriol Romero-Isart of the Max Planck Institute for Quantum Optics in Garching, Germany, and his colleagues hope to prove the concept with the flu virus. By impinging on the virus, it forces it into a superposition of both its ground state and next vibrational energy state. Now the virus should be doing two different things at once.
Interesting. & likely to provide endless fodder for eschatologists and extinction fantasists everywhere.
