Scientists develop molecular code for melanin-like materials

Scientists have long known that melanin—the pigments that give color to skin, hair and eyes—has numerous useful qualities, including providing protection from cancer-causing UV radiation and free radicals, but also electronic ...

Toward a safer permanent hair dye that mimics melanin

Coloring hair has become a common practice, particularly for people who want to hide their graying locks. But an ingredient in many of today's commercial hair dyes has been linked to allergic reactions and skin irritation. ...

Skin pigment could help strengthen foams and fabrics

Melanin is the natural molecule in animals' skin, hair and the iris of eyes that gives them color and helps protect them from ultraviolet light. Someday soon, the pigment could be found in unexpected places such as sofa cushions ...

Video: The world's most unavoidable carcinogen

When we go outside, we expose ourselves to the most common carcinogen of all: ultraviolet (UV) rays in sunlight. Most of us know we should apply sunscreen to protect our skin, but some of us forget and suffer a flaky, irritated ...

Formation of the browning pigment melanin decoded

Melanin is a pigment which is present in almost all life forms and that determines hair and skin color in humans. It helps insects protect themselves against the effects of pathogenic microorganisms and it promotes tissue ...

Study finds that protein puts the brakes on melanin

A year and a half ago, researchers at Brown University found a molecular gas pedal for melanin production. Now they've found a brake. For scientists, the finding deepens not only the basic understanding of how eyes, skin ...
