In this undated photo released by Tokyo University's Department of Biophysics and Biochemistry Graduate School of Science, a genetically modified mouse approaches 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.

Japanese scientists say they've used genetic engineering to create...

Deaf people are making a profound contribution to the study of language Ann Senghas We all speak smile JUST as biologists rarely see a new species arise, linguists rarely see a new language being born. You have to be in the right place at the right time, which usually you are not. But the past few decades have seen an exception.
