Our mission is to provide information about sun protection, skin care and skin disorders and to feature topics in the fascinating field of photobiology. We also cover news and information on the sun and benefits of light.
Research Confirms Genetic Skin Barrier Defect Linked to Eczema
by the American Academy of Dermatology
New studies examining the genetic basis of the condition support the longstanding theory that atopic dermatitis might be caused by a defect in the skin's protective outer layer.
One Protein Produces Skin Color
by American Society for Biochemistry and Molecular Biology.
Skin color is one of the most visible indicators that helps distinguish human appearance, and a new study provides more detail as to how one protein helps produce this wide palette.
Protect Your Pets from Sunburn
by Kim Marie Labak
Before stepping out to enjoy the summer weather, you should protect your pet as well as yourself from the harmful effects of too much sun.
Photosensitivity : Another Reason for UVA Skin Protection
by Diana Clarke
We react normally to sun exposure by developing a tan or sunburn. But some of us react abnormally from photosensitivity. For instance, during the last two summers, I have broken out in a rash from the sun. My doctor said it is contact dermatitis, preciously, photocontact dermatitis. The allergen could even be a sunscreen ingredient.
How to Increase the UPF of a T-shirt
by Diana Clarke
Have you thought about your T-shirt’s UPF? That stands for Ultraviolet Protection Factor, the standard rating system that tests and measures a fabric’s ability to protect the skin from the initial onset of skin reddening caused by UV-B rays?
Urban Heat Island Effect
by Diana Clarke
The Environmental Protection Agency describes the “heat island effect” as “urban and suburban temperatures that are 2 to 10°F (1 to 6°C) hotter than nearby rural areas.”
New Study Indicates Tanning May Be Addictive
by the American Academy of Dermatology
Despite repeated health warnings about the dangers of tanning from sunlight and artificial light sources, there are still those whose mantra "bronzed is beautiful" remains unshaken.
Geoengineering a Solar Filter: The Risks
by The Carnegie Institution of Washington
Radical steps to engineer Earth’s climate could drastically cool the planet, but could just as easily worsen the situation if these projects fail or are suddenly halted, according to a new computer modeling study.
New Study Identifies Five Risk Factors Linked to Melanoma Detection
by the American Academy of Dermatology
Despite repeated health warnings about the dangers of tanning from sunlight and artificial light sources, there are still those whose mantra "bronzed is beautiful" remains unshaken.
Physics for Future Presidents: Physics 10, Lecture 13, Light, from UC Berkeley
Physics 10: Physics for Future Presidents. Spring 2006. Professor Richard A. Muller. The most interesting and important topics in physics, stressing conceptual understanding rather than math, with applications to current events. Topics covered may vary and may include energy and conservation, radioactivity, nuclear physics, the Theory of Relativity, lasers, explosions, earthquakes, superconductors, and quantum physics.
