Sun's Damage Lingers Long After Dark 2015-02-19T05:00:00Z Similar cells from albino mice, which are missing melanin, didn’t show the same effect. Why You Have to Worry About the Sun's UV Rays Even When It's Dark 2015-02-19T05:00:00Z High levels of melanin in dark-skinned people are typically associated with protection against melanoma, because the melanin absorbs UV energy, preventing it from causing DNA damage. You can still get skin cancer in the shade 2015-02-19T05:00:00Z And the damage may rely on the presence of melanin, the skin pigment often thought to protect us from sun exposure. Sun damage keeps happening even after you go inside, new study says 2015-02-19T05:00:00Z Scientists at Yale University, in the US, discovered it was the supposedly protective pigment melanin that was causing the damage. Sunlight harms skin for hours later 2015-02-19T05:00:00Z People with albinism lack pigmentation in their skin and hair due to a lack of melanin, are often sensitive to the sun and face a higher than average risk of skin cancer. Tanzanian gangs hack off limbs of albinos for traditional rituals 2015-02-19T05:00:00Z Once activated, he says, some of the melanin is highly energized, and in that state, starts to degrade. Why You Have to Worry About the Sun's UV Rays Even When It's Dark 2015-02-19T05:00:00Z One of the first planned experiments for the KSU laser will study the behaviour of electrons in atoms of melanin, best known as the pigment that protects skin from the sun’s ultraviolet rays.

Are Light, Heat and Energy the Secrets to Perfect Skin? 2014-11-24T05:00:00Z The hormone — and the drug — triggers skin cells to release the dark pigment melanin, as they do to create a tan when skin is exposed to the sun. Protection: The sunscreen pill : Nature : Nature Publishing Group 2014-11-18T05:00:00Z Spending time in the sun prompts the skin to synthesize new melanin. Skin colour: No hiding in the dark : Nature : Nature Publishing Group 2014-11-18T05:00:00Z No one knows why ultraviolet photons do not normally break the chemical bonds in the molecule when they hit it, but it is assumed that melanin’s electrons redistribute — and diffuse — the energy among themselves. Saudi Arabia opens top-notch laser lab 2015-02-16T05:00:00Z In humans, this new study indicates, the reaction breaks apart the melanin and forms a high energy molecule. Sun damage keeps happening even after you go inside, new study says 2015-02-19T05:00:00Z These cells contain a pigment called melanin, which absorbs damaging ultraviolet rays from the sun.

Skin colour: No hiding in the dark : Nature : Nature Publishing Group 2014-11-18T05:00:00Z The pigment melanin is also a potential source of unpaired electrons, but a similar result was obtained by melanin-depleted mutant strains. Electron Theft, Not Drug Effects, May Be How Anesthesia Knocks People Out 2014-08-13T04:00:00Z Last year, biomaterials scientist Christopher Bettinger of Carnegie Mellon University in Pittsburgh, Pennsylvania, unveiled an edible sodium-ion battery with electrodes made from melanin pigments. Biodegradable Battery Could Melt Inside the Body 2014-03-25T19:35:00Z Another idea is that the increased production of melanin might form a protective shield against the harmful rays. Risk factors: Riddle of the rays : Nature : Nature Publishing Group 2014-11-18T05:00:00Z One suggestion often proferred is that the melanin in black skin, by absorbing ultraviolet light which might otherwise damage DNA and cause mutations, protects against skin cancer. Human evolution: The skinny on skin colour 2014-02-27T16:07:00Z Darker skin contains more melanin, a pigment that protects against ultraviolet rays. Skin colour: No hiding in the dark : Nature : Nature Publishing Group 2014-11-18T05:00:00Z Finally, its exterior contains melanin, the same pigment that colors human skin, which both protects it from UV radiation as well as inhibits the digestive action of macrophages.

Being Well-Born An Introduction to Eugenics 2012-05-22T15:16:53.140Z Granules of melanin in the cell walls of fungi also absorb certain substances — including many drugs — preventing them from gaining access to the interior. Deadly meningitis outbreak puts researchers in new territory 2012-10-20T23:18:19Z So the researchers conducted a variety of chemical tests, including placing samples of material scraped from the fossil in a solution that typically breaks down melanin pigments. ScienceShot: Pigment Preserved in 162-Million-Year-Old Fossils 2012-05-21T20:00:00Z In this condition the black granules of pigment, although differing in color and form from h�matoidin, contain iron, and have received the name melanin. A System of Practical Medicine by American Authors, Vol. I Volume 1: Pathology and General Diseases 2012-03-17T02:00:54.097Z "Essentially, these all work in different ways to eliminate the pigment, which is called melanin," she said, adding, "They're all mildly effective." Skin brighteners find a welcome 2012-02-25T04:58:04Z But in South Africa's black-and-white present, Zille is only too aware that she has a "melanin deficit." How the ANC Lost Its Way 2012-01-06T11:25:00Z This is in keeping with Gloger's Rule, which states that melanins increase in the warm and humid parts of the range of a species, and reddish or yellowish-brown phaeomelanins prevail in arid climates. Speciation and Evolution of the Pygmy Mice, Genus Baiomys 2011-12-15T03:00:11.933Z Moles, for instance, are collections of senescent cells that continue to produce melanin and defend the skin from ultraviolet rays.
