Computer simulations and laboratory experiments have shed light on how an asymmetric pattern of gene expression is fixed in vertebrate embryos — an early step towards asymmetric development of the ...

Our guts, and all our organs, are arranged in left-right asymmetric patterns inside our bodies, so that everything may fit. At the same time, development of organs such as the intestine is anything ...

On the outside, animals often appear bilaterally symmetrical with mirror-image left and right features. However, this balance is not always reflected internally, as several organs such as the lungs ...
