French twins Thomas and Vincent (L) Seris take the tram in Bordeaux, November 12, 2014. Born with Xeroderma Pigmentosum (XP), the twins cannot be exposed to the sun and its ultraviolet (UV) light, which could provoke precocious cancers due to an autosomal recessive genetic disorder of DNA repair. Colloquially referred to as Children of the Night (Les Enfants de la Lune) the Seris twins are among 70 to 80 people in France who suffer from the genetic defect. The French association “Les Enfants de la Lune” reports that there are between five and ten thousand such cases in the world. Thomas and Vincent have been testing a new protective mask for the last year which is transparent and ventilated and developed by several hospitals in France. (Photo by Regis Duvignau/Reuters)

Los Angeles native Mike Stilkey has always been attracted to painting and drawing not only on vintage paper, record covers and book pages, but on the books themselves. Using a mix of ink, colored pencil, paint and lacquer, Stilkey depicts a melancholic and at times a whimsical cast of characters inhabiting ambiguous spaces and narratives of fantasy and fairy tales. A lingering sense of loss and longing hints at emotional depth and draws the viewer into their introspective thrall with a mixture of capricious poetry, wit, and mystery. (Photo by Mike Stilkey)
