The article on nanotubes as light sources was frustratingly sketchy. Any photometric laboratory with a wattmeter could compare the nanotube unit to another light source in a few minutes. It is tempting to think that the heating effect, which must be close to that from a blackbody radiator, and the “electronic effect,” which is undoubtedly […]

When cyanobacteria and plants transfer electrons photosynthetically, light is absorbed not by their photosynthetic proteins but by chlorophylls. Some of these proteins indeed participate in electron flow, but they are not plant photoreceptors.
