Summit Supercomputer Draws Molecular Blueprint for Repairing Damaged DNA

Sunburns and aging skin are obvious effects of exposure to harmful UV rays, tobacco smoke and other carcinogens. But the effects aren’t just skin deep. Inside the body, DNA is literally being torn apart. Understanding how the body heals and protects itself from DNA damage is vital for treating genetic…
