How skin cells protect themselves against stress

Cell biologists have developed a new method for measuring how mechanical forces in cells are processed.

Rapid genetic evolution linked to lighter skin pigmentation

The gene that causes lighter skin pigmentation, SLC24A5, was introduced from eastern African to southern African populations just 2,000 years ago. Strong positive selection caused this gene to rise in frequency among some KhoeSan populations.

The naked eye alone is not enough to ensure the accurate diagnosis of skin cancer, say experts

The visual inspection of a suspicious skin lesion using the naked eye alone is not enough to ensure the accurate diagnosis of skin cancer, a group of experts have concluded.

World's smallest wearable device warns of UV exposure, enables precision phototherapy

Smaller than your thumbnail and thinner than a credit card, a new device can optimize treatment of neonatal jaundice, skin diseases, seasonal affective disorder and reduce risk of sunburns and skin cancer.

Realistic exposure study supports the use of zinc oxide nanoparticle sunscreens

An important new study provides the first direct evidence that intact zinc oxide nanoparticles neither penetrate the human skin barrier nor cause cellular toxicity after repeated application to human volunteers under in-use conditions. This confirms that the known benefits of using ZnO nanoparticles in sunscreens clearly outweigh the perceived risks, researchers say.
