Scientists have discovered a gene that determines whether Japanese snails develop shells that are left- or right-coiling—with implications for understanding the underlying handedness of our own bodies. The researchers from the University of Nottingham and Tohoku University studied wild Euhadra snails in Japan to understand what makes one snail a mirror image of another.
