As the new hockey season kicks off, mind your heart: A new study suggests that watching hockey can cause significant cardiovascular stress, similar to that of moderate to vigorous physical exercise. Researchers observed two groups of sports fans using Holter monitors, with one group watching hockey games on TV and the other attending the games […]

Researchers pinpoint the heart’s pump-up protein 
Scientists have discovered a protein that promotes healthy heart growth by helping this key muscle pump blood efficiently throughout the body. The protein, cardiotrophin 1 (CT-1), stimulates both the growth of heart muscles and the growth of blood vessels in the heart. The effect of CT-1 is similar to what is naturally achieved through exercise or […]
Biological pacemakers out of stem cells
The sinoatrial node (SAN) is the heart’s primary pacemaker. The failure of its functions causes multiple cardiac problems, such as a lower heart rate and decreased blood circulation. These issues are typically addressed with a mechanical pacemaker. But a new study describes how a biological pacemaker can be developed out of pluripotent stem cells. Such […]
