Why Become a Scientist?

Reason #1: So you can tell poisonous salad from non-poisonous salad in your local supermarket.

A trained botanist in Hanover, Germany was buying some pre-packaged salad when he noticed the abundance of common groundsel (senecio vulgaris). Knowing a little bit about plants, they alerted the store who removed all the salad from the shelves and sent a sample to the University of Bonn for testing.

The University labs detected 2,500 micrograms of poison in 150g of salad (and in a brilliant bit of journalism, Reuter's online points out that this is 2,500 times more than the recommended amount of daily poison).
