ONLINE COVER It's Electric! An iridium electrode's spark generates nitric oxide from ambient air. In this issue, Yu and colleagues packaged this spark into a portable, lightweight device, so that nitric oxide can be easily delivered to patients in emergency rooms or in their own homes. The respiratory device was first tested in lambs with pulmonary hypertension, performing as well as traditional tank-delivered nitric oxide. [CREDIT: B. WILSON/MASSACHUSETTS GENERAL HOSPITAL]
