Meredith Patterson is not your typical genetic scientist. Her laboratory is based in the dining room of her San Francisco apartment. She uses a plastic salad spinner as a centrifuge and Ziploc plastic bags as airtight containers for her samples. But the genetically modified organism (GMO) she is attempting to create on a budget of less than $500 (£350) could provide a breakthrough in food safety.
The 31-year-old ex-computer programmer and now biohacker is working on modifying jellyfish genes and adding them to yoghurt to detect the toxic chemical melamine, which was found in baby milk in China last year after causing a number of deaths, and kidney damage to thousands of infants. Her idea is to engineer yoghurt so that in the presence of the toxin it turns fluorescent green, warning the producer that the food is contaminated. If her experiment is successful, she will release the design into the public domain.
