The hamadryas baboon is one primate species that fails the mirror test.. The mirror test—sometimes called the mark test, mirror self-recognition (MSR) test, red spot technique, or rouge test—is a behavioral technique developed in 1970 by American psychologist Gordon Gallup Jr. as an attempt to determine whether an animal possesses the ability of visual self-recognition.

Only a few animal species have been shown to have the ability to recognize themselves in a mirror, most of them mammals. Experiments have found that the following animals can pass the mirror test: Humans. Humans tend to fail the mirror test until they are about 18 months old, or what psychoanalysts call the "mirror stage". [104] [105] [106]
Animal multilayer reflectors work in the same way as a man-made dielectric mirror (or Bragg mirror) being composed of alternating layers of high and low refractive index, the thickness of each layer being 1/4 the wavelength most strongly reflected. [8] To reflect a wide range of wavelengths, the spacing must vary through the thickness of the ...

Space mirrors are designed either to increase or decrease the amount of energy that reaches a planet from the sun with the goal of changing the impact of UV radiation; or, to reflect light onto or deflect light off of a planet in order to change the sun's lighting conditions.
Another possible mechanism of magnetoreception in animals is electromagnetic induction in cartilaginous fish, namely sharks, stingrays, and chimaeras. These fish have electroreceptive organs, the ampullae of Lorenzini, which can detect small variations in electric potential. The organs are mucus-filled and consist of canals that connect pores ...
The report said that if a cell with natural chirality can be created from lifeless molecules, then, in theory, a mirror-image cell could be created from mirror-image molecules using the same methods.
