Editor's Note: The extended Q&A with Jeremy Nicholson mentioned in the July magazine can be found here. Jeremy Nicholson was only trying to be thorough.

In particular, Nicholson wanted to study how red blood cells absorb cadmium, a metal that causes cancer. Realizing that he would achieve the best results if he could mimic the cells’ natural environment, he added a few drops of blood to the cells and ran the test. [More]
