Interesting NYT article on NASA's research about germs and space.
After 25 days, 40 percent of the mice given the Earth-bound salmonella were still alive, compared with just 10 percent of those dosed with the germs from space. And the researchers found it took about one-third as much of the space germs to kill half the mice, compared with the germs that had been on Earth.
Why? Well, because everything is scarier once space is involved. Insert creepy theremin noises here.
