Just Why are Some People More Attractive Than Others?

Oxidative stress and antioxidants could be the reason why some people are more attractive than others, a recent study has found.

Psychologists have discovered that men who were rated as the most physically attractive by women have the lowest levels of markers of oxidative stress.

Heart Disease Risk may be Predicted by Marker of Oxidative Stress
A substance in the blood that may be useful in predicting a person's risk for heart disease has been discovered by scientists.

"These findings have several important implications," the Independent quoted psychologist Dr Steven Gangestad, who led the study, as saying.

"They fit in with the idea that women evolved to find particular features attractive because those features are related to low levels of oxidative stress," he stated.

Researchers found that it is not a chosen trait but one that is inborn, and which has evolved over time as a way of distinguishing the virile from the weak.

Study Finds Oxidative Stress a Primary Cause of Genetic Mutations
American scientists have shown for the first time that oxidative DNA damage is a primary cause of the process of mutation

As cells use oxygen to make energy, they can create free radicals. These are unstable molecules that can have chemical reactions with other molecules, causing the cell damage known as oxidative stress.

Free radicals can be kept in check by antioxidants, but if there is an overabundance of radicals, the resulting oxidative stress can damage DNA and tissue.

Scientists Develop New Method to Monitor Early Sign of Oxidative Stress That Triggers Cancer
A new method to monitor early sign of oxidative stress that triggers cancer spread has been developed by scientists from University of Michigan.

Oxidative stress is thought to be a major cause of mutations and to play a part in ageing and a host of diseases, including cancer.

The findings have been published in the journal Animal Behaviour.

Oxidative Stress is the Underlying Cause to Genetic Mutations
Oxidative DNA damage is a primary cause of the process of mutation, according to a study that tracked genetic mutations through the human equivalent of about 5,000 years.
