SUMMARY
Designing molecules that can rearrange in response to electromagnetic signals, particularly radio frequencies, presents significant challenges due to the size of the wavelengths involved and the thermal fluctuations at conventional temperatures. The discussion highlights that at lower frequencies, thermal noise can randomize molecular arrangements unless cooled to near single-digit Kelvin temperatures. Nature has evolved temperature-sensitive sensory components in organisms, such as the heat vision of pit vipers, which involve protein reconfigurations but do not directly respond to infrared signals. The concept of moths detecting pheromones through infrared colors has been largely discounted due to these thermal equilibrium issues.
