Since 2011, Andy Gracie has been selectively breeding flies to thrive under the harsh environmental conditions on Titan, Saturn's largest moon: dark, cold (-179.2C), and with very low atmospheric pressure.
Gracie is breeding Drosophilae (he calls his species Drosophila Titanus), a species with a long history of being sent into space as part of experiments seeking to understand the effects of space on living organisms.
Gracie's interview with We Make Money Not Art is a fantastic look at the strange world of bioart, the difficulties posed by life in space, and the strange, modern accessibility of biological manipulation techniques.
The chamber is an apparatus that has evolved over time as the project has developed. I’m not a great forward planner so the device adapted as I had new ideas or as new necessities presented themselves. The first consideration was being able to make it cold, then to add LEDs that would simulate the Titan lighting conditions. I was lately developing seals that would allow the internal pressure to be increased in order to begin the atmospheric pressure experiment. Future experiments would probably have demanded the fabrication of an entirely new device.
Outside of the main simulator I also made the gravitational realignment torus, it being impractical to rotate the main apparatus. This device did not have a cooling system so gravitaxis experiments had to take place in the winter with the heating off.
A large part of the project for me was drawing from my background in DIY culture – how to improvise experimental apparatus outside of a laboratory or research facility. I was interested in how subtle adjustments of everyday objects and situations can provide conditions that are not typically terrestrial.

Chris Veltri, proprietor of San Francisco’s legendary Groove Merchant record shop, posted this astounding artifact to his Instagram wunderkammer of outré culture paper ephemera @collagedropoutsf! It’s a poster for a lecture by artificial intelligence pioneer Herbert Simon that took place at UC Berkeley in 1974. The speech was titled “How Man and Computers Understand Language.” […]
Andy Thomas, the artist who creates wonderful paintings depicting historical presidents from each party hanging out, has updated The Republican Club to include Donald Trump. It was spotted on the White House wall during an interview with the president on CBS News. The artist, who lives in Missouri, United States, was “ecstatic” to discover his […]
The University of Michigan's library recently acquired a copy of American Cheese, 20 Slices, by Ben Denzer, a book made from shelf-stable, plastic-wrapped slices of American cheese.

Multinational companies have used the no-nonsense methodologies of Six Sigma and Lean Six Sigma to oil a smooth-running operation for years. What is it? Six Sigma (and its offshoot, Lean Six Sigma) apply the principles of science to business, teaching managers to methodically target waste, maximize output and streamline the flow from producer to consumer.
