Newly developed methodology breaks molecular symmetry to back one theory about life's origin

The vast majority of organic molecules (based on a carbon structure) are not flat, but have a three-dimensional geometry. Various results can be obtained depending on the way the atoms are arranged inside each molecule. In ...
