I don't understand how aluminum reflects hormones. Hormones are not radiant, they're proteins. I need a better explanation of the mechanism before I can wrap my mind around it. That's not to say that I don't believe the data, I just don't quite understand the exact mechanism by which a secreted hormone is reflected by aluminum and why something insular like plastic wrap or plastic in general (maybe making a nestbox out of a cooler) doesn't have a greater effect than aluminum. I understand about wavelengths of light, but hormones aren't light, they don't adhere to the properties of a photon, how is this possible? Someone please explain and be as technical as possible, I have a background in molecular bio, so I can understand the physics and biochem aspects if they're explained to me, I just can't noodle them out myself. Sorry to be the skeptic, I guess I read too much Sagan.
