Maker Faire New York: Studying Evolution with Robots

Vassar college Professor John H. Long is a marine biologist, by training, and, now, a roboticist by trade. Essentially, he builds robot populations closely modeled on extinct (and living) fish, and then subjects them to simulated evolutionary pressure—to hype it up a bit, he “pits them against each other”—to learn things about why historical animals evolved as they did…

Maker Faire New York: Using Microbes to Etch PCBs

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…
