Solar panels in your eyeballs: Self-powered bionics are on the way

sunlight activates specific neurons in the eye called intrinsically photosensitive retinal ganglion cells that indirectly control blood flow and support the ciliary body (which controls the aperture of the eye) to improve eye health. Those mechanisms may explain why getting outside for 2+ hours/day of sunlight can protect from and possibly help rev... See more

Even collecting 1% of the sun's energy is an unbelievable change in our species' energy budget. We could create the infrastructure to beam basically unlimited amounts of energy around the solar system for all sorts of projects — colonies on other worlds, terraforming planets, constructing more mega structures, or even traveling to other stars. It c... See more

As human beings, we can perceive less than ten trillionth of light waves. "Our experience of reality," says neuroscientist David Eagleman, "is limited by our biology." He wants to change that. His research on brain processes has led him to create new interfaces, such as a sensory vest, to process unpublished information about the world around us.
