When a bee passes through, the order in which the sensors are tripped reveals if it is coming or going.

Acidithiobacillus ferrooxidans is a gram-negative bacterium that lives, in the natural world, in iron sulfide (aka “pyrite,” aka “fool’s gold) deposits, where it eats iron and sulfur and excretes sulfuric acid. Now, a team of graduates, undergraduates, and post-docs at New York’s Columbia and Cooper Union universities is working to develop a genetically-modified strain of A. ferrooxidans…
