heart defibrillation using lightMany recent technological advances in medicine and in other areas have been achieved by harnessing light in some manner. I have written on a number of occasions how I believe that this century’s innovations will be driven by finding new ways to control and apply light energy.

The most recent news on this front comes from a story at MedGadget about studies performed at Johns Hopkins University. Controlling light patterns using optogenetic techniques has been proven to stop arrhythmias in mouse hearts. The Hopkins researchers were able to obtain similar results on a digital simulation of a human heart.

Of course, there is much development that needs to be done to move the technology out of the digital realm and into the physical. Still, the Hopkins study points to the new possibilities that could be achievable by harnessing the power of light.
