During the Bucky Ball presentation at the MRL, we learned that bacteria have magnetic particles inside. Can you explain why and what for do this magnetic particles are there?
Question Date: 2011-05-19
Answer 1:

These bacteria are called magnetotactic bacteria, when means they are bacteria that can "feel" magnetism. They "feel" the magnetism of the earth (the same magnetism that makes compasses point to the North) using the little magnetic particles inside them. This helps orient them with the earth's magnetism and helps them get towards where the food is.

Hope this helps,
