Americans are sun worshippers, but having that bronzed body is causing skin cancer rates to rise and it can be deadly.
Olaf Wiest is a professor of chemistry and biochemistry at Notre Dame.
He has developed a molecule that may help repair skin cell DNA, damaged by excessive ultra violet light.
This basic research puts us a step closer to preventing skin cancer.
Wiest said, "The hope would ultimately be, you get to the point where you could apply this molecule after the damage was done, so the day after you got your sunburn you will just, like a sunscreen the day after, and it would repair the damage that is done and prevent the skin cancer."
How soon could we see a product like this on the market?
We will take you inside Dr. Wiest's lab at Notre Dame, where this breakthrough was discovered.
Tune in tonight at 11 for the sunburn pill.
