Scientists report that knocking out the Lsdia1 gene using CRISPR in the freshwater snail Lymnaea stagnalis reverses the direction of shell coiling. The snail shell typically coils in the right-handed or dextral direction, but the snails with the Lsdia1 gene knocked out coil in a left-handed or sinistral direction.
