Chemists create 'Superbowl' molecule; May lead to better health

... by the name tetrabromo-superbowl (C268H320O52Br4) due to the addition of four bromine atoms. The bromine atoms make the hole at the top of the molecule smaller, which makes it more difficult for things to pass in and out. This is ideal if you're trying to capture certain molecules and hold them until th...
