Heat-Damaged DNA in Food Linked to Possible Genetic Risks

Researchers have newly discovered a surprising and potentially significant reason why eating foods frequently cooked at high temperatures, such as red meat and deep-fried fare, elevates cancer risk. The alleged culprit: DNA within the food that's been damaged by the cooking process.

How the Natural Process of DNA Repair Fails to Cause Disease

We often come to an understanding of what causes a disease. We know, for example, that cancers are caused by mutations at critical locations in the genome, resulting in loss of control of cell growth.

New method helps distinguish bacterial DNA from human and other non-bacterial cells

For decades, a small group of cutting-edge medical researchers have been studying a biochemical, DNA tagging system, which switches genes on or off. Many have studied it in bacteria and now some have seen signs of it in, plants, flies, and even human brain tumors.
