    1. Very interesting. I recall seeing a similar study on copper effects in hospitals, though it focused more on elimination of bacteria. It's quiet incredible how the species have such a 'prey' instinct to try and survive even at this small level of life!

      1. Oh yeah, Michael Schmidt from This Week in Microbiology has done some research on copper in hospitals.
