In this undated photo released by Tokyo University’s Department of Biophysics and Biochemistry Graduate School of Science, a genetically modified mouse stays near a cat in Tokyo. Using genetic engineering, scientists at Tokyo University say they have successfully switched off the rodents’ instinct to cower at the smell or presence of cats, showing that fear is genetically hardwired and not leaned through experience, as commonly believed.
