this scientific fact puts an end to the false doctrine of white superiority
scientist found melanin to be a superconductor absorbing and transforming energy and protecting the body and enhancing the immune system, they found even dark melanin rich mushrooms which can use radioactive energy for growth, people with melanin rich substantia nigra are also protected against alzheimers and parkinsons and other diseases

Some scientists believe having a larger amount of melanin protects black people from noise-induced hearing loss (NIHL) as the years go by, said NIOSH researcher William Murphy, PhD. Melanin may play a role in how the body removes harmful chemical compounds caused by damage to the sensitive hair cells in the inner ear.1
The NIOSH study looked at more than 5,000 people who had hearing tests from 1999 through 2004 as part of an annual federal health survey. The tests revealed that, on average, non-Hispanic blacks could hear higher tones at 15 to 22 dB, compared to 16 to 25 dB for Mexican Americans and 21 to 32 dB for non-Hispanic whites.
Previously, research on workers exposed to occupational noise showed that those with darker skin and/or eyes tend to have greater resistance to NIHL. The inner ear is lined with well-circulated tissues of multiple layers of cells, explained Ulrich Schraermeyer, a cell biologist at the Centre for Eye Medicine at the University of Cologne. He contends that inner-ear melanin protects the cochlea from loud noise by counteracting the formation of free radicals, the dangerous molecules released during cellular damage.2
Melanin is a dark pigment that occurs naturally in human skin, hair, the iris and retina of the eye, as well as the adrenal gland, inner ear, and parts of the brain. It is manufactured in the basal layer of the epidermis and produced by cells called melanocytes. All people have roughly the same number of melanocytes, but there is a greater expression of melanin in some racial groups. One of the basic functions of melanin is to protect the body from the harmful effects of the sun.
The effect of melanin on the inner ear remains conjectural.3 However, there is parallel research on the eye.
Researchers at the University of Chicago have shown that melanin acts like a "neutralizing sponge" inside cells in the retina to soak up and destroy reactive oxygen species. These free radicals are energized by light and thought to play a major role in macular degeneration, the leading cause of blindness in people over age 60. The disorder is far more prevalent among whites than blacks.
