In a series of three review papers, published in the journal Pigment Cell & Melanoma Research, the authors suggest that indoor tanning beds, used mainly by young women, are linked to an increased risk of melanoma, the most dangerous form of skin cancer.

They have even recommended banning under-18s from using such beds as well as any publicity material claiming that tanning beds are safe.

According to the study’s researchers, the findings suggest that domestic dogs have the capacity for a fundamental form of empathy.
