A small, simple plastic device they’ve developed, when attached to the screen of a cell phone, can scan the eye and determine the appropriate

Using stem cell therapy, a team of Italian researchers was able to restore sight for patients who had been blinded or suffered severely impaired vision after suffering a chemical burn. In a study of 106 patients treated between 1998 and 2007, researchers were able to extract adult stem cells from healthy eye tissue, grow additional stem
