World first research to speed up cure for ear infections

...funding we can start our studies to understand how wounds in ear drums heal themselves by examining the cells and molecules in the replacement tissue," Dr Ghassemifar said. "Through DNA or gene profiling of animal models we hope to learn which molecules are active as the ear drum heals and we will then tar...
