A team of European researchers says hair grays with age as follicles become bleached first gray, and then white, from within. The researchers closely examined cell cultures of human hair follicles and found in the absence of the enzyme catalase, the hydrogen peroxide naturally produced in hair cells stops being broken down into water and oxygen. Also, hair follicles could not repair the damage caused by the accumulating hydrogen peroxide because of low levels of enzymes MSR A and B. High...

A team of scientists from the University of Valencia (UV) has proven that traces of blood in various materials are eliminated completely when they are washed with detergents containing active oxygen. The conclusion of the study, published in the latest number of the German journal entitled Naturwissenschaften, points out that these new products alter blood to such an extent that this cannot be detected by reagents used in criminalistics. The intention of the authors of a crime is not to leave...
