Biologists at Goethe University Frankfurt , Germany , studied skin healing in fruit fly embryos using an electron microscope to watch what happened . They found that the cells of a single embryo were able to heal themselves after being damaged by UV radiation and then regrew into new tissue. Researchers hope it may help develop new treatments to speed up healing .
