Genetic study provides novel insights into the evolution of skin color

Skin color is one of the most visible and variable traits among humans and scientists have always been curious about how this variation evolved. Now, a study of diverse Latin American populations has identified new genetic variations associated with skin color.

Blister fluid could help diagnose burn severity

Severe burns can leave physical and psychological scars, especially in children. When a burn patient enters the clinic, doctors use factors such as the depth and size of the burn, as well as the time required for skin healing -- or re-epithelialization -- to determine the best course of treatment. Now, researchers have found another, possibly more accurate way to classify burn severity: analyzing proteins in blister fluid.

Unraveling the genetic causes of skin cancer

Medical researchers are helping to identify the genetic factors that lead to squamous cell carcinoma. In a new article, they show how the interaction between a cell signaling pathway called MET and a gene, Tpl2, contributes to skin cancer progression.

How 'Dry January' is the secret to better sleep, saving money and losing weight

New research shows that taking part in Dry January sees people regaining control of their drinking, having more energy, better skin and losing weight. They also report drinking less months later.

How skin ages, loses fat and immunity

Some dermal fibroblasts can convert into fat cells that reside under the dermis, giving skin a youthful look and producing peptides that fight infections. Researchers show how this happens and what causes it to stop as people age.
