A humble 1 houseplant with a dash of rabbit DNA 2 could help lower our exposure to indoor air pollution, new research suggests. Scientists have revealed that by inserting a rabbit gene 3 into devil’s ivy 4 the plant is able to clean the surrounding air by breaking down chemicals such as benzene and chloroform, which in certain concentrations can harm health. The researchers say these chemicals end up in household air as a result of everyday activities, with chloroform released from chlorinated water during showering, and benzene from sources including outside air and smoking.
