Even when something evolves specific nanostructuresthat strongly scatter red lightthey still resonate with other wavelengths,

Just think of people at a checkout lineor at a red light.Being alone feels like a problem that needs to be solved.

Gamma rays and X-rays do that, too, but they cause tumors.Red light is all around us.So, using that, I'm going to come back here
