New research challenges the most popular theory about why our bodies deteriorate in old age. Scientists know that as we grow older our cells accumulate particles, called free radicals. It has long been thought that free radicals wreak havoc by damaging proteins and impairing their function – but the new research shows that proteins can survive unscathed.

Center for Self-Assembly and Complexity within the Institute for Basic Science (IBS) Director Kimoon Kim and his team experimented with nitric oxide, a highly stable molecule of supreme importance in science. NO is highly reactive and a free radical, meaning a single, unpaired electron is present in its molecule. read more

Antioxidants are a class of molecules that are capable of inhibiting the oxidation of other molecules. Within the body, this means that antioxidants fight free radicals (highly reactive atoms or group of atoms, for those of you who are...Show More Summary
Lesions in DNA can occur as often as 100,000 times per cell per day. They can be the result of normal metabolic activities, like free radicals, as well as exposure to environmental factors such as UV radiation, X-rays and chemical compounds. Show More Summary
Antioxidants provide long-term protection against the chain reactions of free radical processes, in other words, of the molecules that are capable of causing cell damage and generating various diseases. Free radicals harm our body by causing, in the best of cases, ageing and, in the worse, serious diseases. Show More Summary
New research with mice undercuts widely held belief that ubiquinone protects cells against damage from free radicals. The popular dietary supplement ubiquinone, also known as Coenzyme Q 10, is widely believed to function as an antioxidant, protecting cells against damage from free radicals. Show More Summary
The popular dietary supplement ubiquinone, also known as Coenzyme Q10, is widely believed to function as an antioxidant, protecting cells against damage from free radicals. But a new study finds that ubiquinone is not a crucial antioxidant.
Many people assume e-cigarettes are a healthier – or less unhealthy, at least – option than regular cigarettes. While the long-term effects of e-cigarettes are still unknown, research out of Johns Hopkins University has found that e-cigs may deliver a false sense of security along with their nicotine hit...

A new study shows that emissions from e-cigarette aerosols and flavorings damage lung cells by creating harmful free radicals and inflammation in lung tissue, suggesting that e-cigarettes are likely a toxic replacement for tobacco products. The study also shows that some flavored e-juices -- particularly cinnamon -- create more stress and toxicity on lung tissue.
Antioxidants are natural food ingredients that protect cells from harmful influences. Their main task is to neutralize so-called "free radicals" which are produced in the process of oxidation and which are responsible for cell degeneration. Scientists...Show More Summary
