Controlling-heart-waves-with-light
2015 21 Oct
A team of researchers from Stony Brook University and Oxford University have found a way to control the electrical waves of the heart - using light. The findings are published in Nature Photonics. The rhythm of the heart is regulated by electrical waves. If this rhythm goes awry, it may result in potentially fatal arrhythmia. Currently, there...Read more
