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

In a development that could one day score a touchdown for better health, chemists in Australia have created a "superbowl" molecule that shows promise for precision drug delivery, according to a recent study in the Journal of the American Chemical Society. Shaped like a miniature football sta...
