In a recently published scientific paper, researchers demonstrated how a transparent layer of electrodes on a polymer surface could be extraordinarily tough and flexible, withstanding repeated scotch tape peeling and bending tests.

Sleep apnea tied to diabetes in large study
In the largest study to date of the relationship between sleep apnea and diabetes, a new study of more than 8,500 Canadian patients has demonstrated a link between obstructive sleep apnea and the development of diabetes, confirming earlier evidence of such a relationship from smaller studies with shorter follow-up periods.
