September 2021: Carmit Levy: UV radiation enhances romantic passion
Prof. Carmit Levy (Medicine) published a new study in Cell Reports: Exposure to sunlight affects the regulation of the endocrine system, responsible for the release of sexual hormones in humans.
Prof. Carmit Levy, Edmond J. Safra affiliate, and her lab students, found out that the very same protein in the skin cells that protects DNA from being damaged by sunlight — p53 — causes hormonal, physiological and behavioral changes that trigger sex in animals and seemingly also get humans in the mood for love.

The findings were published as a cover story in the scientific journal Cell Reports and were extensively covered in the media around the world:
