 本期内容：

A humble1 houseplant with a dash of rabbit DNA2 could help lower our exposure to indoor air pollution, new research suggests. Scientists have revealed that by inserting a rabbit gene3 into devil’s ivy4 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.
