A girl puts her hand in a box with male genetically modified Aedes aegypti mosquitoes at an educational exhibition by British biotechnology company Oxitec in Piracicaba March 5, 2015. Oxitec said its laboratory created the genetically modified male Aedes aegypti mosquitoes, which are set to be released in Sao Paulo in April. A specially-made gene in the male mosquitoes seeks to reduce to number of Aedes aegypti mosquitoes by killing their offspring after mating with wild female mosquitoes. Brazil already has more than 100 000 cases of people with dengue in 2015, according to the City Department of Health. REUTERS/Paulo Whitaker (BRAZIL - Tags: SCIENCE TECHNOLOGY HEALTH)

French twins Vincent (R) and Thomas Seris shop for food in a commercial centre in Bordeaux, November 12, 2014. Born with Xeroderma Pigmentosum (XP), Vincent Seris and his twin Thomas cannot be exposed to the sun and its ultraviolet (UV) light, which could provoke precocious cancers due to a 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. Picture taken November 12, 2014.
