I think this discovery is very exciting. Â In the early online edition of the journal Nature, scientists report that they were able to observe the "healing" of a DNA strand that had been damaged UV radiation. Â They observed an enzyme inject a single electron and proton into a damaged strand of DNA. Â This enzyme known as photolyase was able to heal the DNA in a billionth of a second.
Many teenagers have acne and one of the most difficult issues with treatment is consistency. Â Teens have busy lives and often don't think about their skin care regimen every morning and night.
Scientists have recently discovered an important mechanism the skin uses to form scars after an injury. Normally when the skin is injured special cells come in and produce proteins like collagen that act as a scaffolding for the full repair of the skin.
...In a recent study published in the Proceedings of the National Academy of Sciences investigators found that a sticky compound found in sunless tanners may help with wound healing after surgery.
...A recent study published in The Journal of the American Academy of Dermatology shows that skin cancers that occur on the face, occur more commonly on the left side.
This shows that people need to be aware of all the situations that expose them to the sun. This includes not only professional drivers but also people who commute regularly.
A new report is out on the prevalence of herpes simplex virus, type 2 (HSV-2) in the United States between 2005 and 2008 and it shows some interesting statistics.
- About 16% of Americans between 14 and 49 years old have genital herpes.
- This percentage is about the same as 1999 to 2004 data.
- 81% of those infected with HSV-2 have not been diagnosed.
- More women and non-Hispanic blacks have HSV-2 than any other demographic.
- 21% of women have HSV-2 which is almost double the prevalence in men.
- 39% of non-Hispanic blacks have HSV-2 which is 3 times higher than the prevalence in whites.
Scientists have learned that lacking a certain omega-6 fatty acid causes severe dermatitis. Â In a recent experiment investigators found that mice who don't have the gene that helps produce arachidonic acid, an omega-6 fatty acid, develop severe dermatitis that causes ulcers and severe itching. Â The itching went away when arachidonic acid was added to their diet.

In a study published in the Journal of the National Cancer Institute researchers found that with a sun safety program it is possible to get kids in school to consistently wear sun protection hats. Â The study also showed that kids did not consistently wear the hats at home and wearing hats consistently didn't prevent new moles or freckles.
