White Island sits 30 miles off the coast of New Zealand. This is an active volcano, 150,000 years old and still steaming. Cracks in the volcano called fumaroles allow sulphurous gases to escape and crystalize. The volcano’s crater lake reaches 122 degrees Fahrenheit and has a pH of 1, signifying its extreme acidity and inability to sustain human, plant, or animal life. But White Island is not entirely uninhabitable: primitive microbes known as extremophiles live in the crater lake, giving it a distinctive bright green color.

Victoria demonstrates the use of E. coli bacteria in the creation of synthetic blood. By altering the genetic make-up of E. coli, bioligists can use the spliced genes in the synthesis of everything from vaccines to biofuels and even the hemoglobin in human blood. There are complications with using this synthetic blood as a complete substitute in human bodies, but Victoria is hoping to excel beyond these roadblocks.
