A ventricular assist system, or VAD, is a implantable device that is used to help a failing heart pump blood through the body, often while the patient is awaiting a heart transplant. It consists of a control system and an energy supply worn outside the body and a pump implanted by the heart or in the abdominal pouch.

Why did the proverbial Good Samaritan cross the road to help the injured stranger? Perhaps he listened to his heart. Not in the poetic sense, but literally. A new study by Jun Gu and his colleagues has highlighted the way cardiac feedback influences people's moral decisions.
