From New Scientist:

New concerns over safety of arsenic in drinking water

I was browsing the headlines and I had to stop at this one.  Arsenic?  In the drinking water?  Isn’t arsenic, you know, poisonous?  And what do they mean new concerns?

But it turns out that we’re only talking about 10 parts per billion, and the experiments were done on mice, which react differently to arsenic than humans do.  Suddenly I feel a lot safer.

It made me wonder though, how many experiments which cause panic and health scares are based on science done on mice.  Could a future scientist use mouse-trials to scare the population into thinking their new whatever is dangerous, while secretly using it themselves to advance their position in the world?

What would happen when they were caught using it?
