Light therapy may combat fungal infections, new evidence suggests

... "Fungi have many negative implications for human life as they lead to human disease, as well as plant disease and mold," said Idnurm, a post-doctoral fellow at Duke. "However, fungi also play important beneficial roles, for example, as a source of food and pharmaceuticals. "Therefore, an understanding ...
