All the times our eyes are open, a complex cascade of events goes on to interpret the sights, even if we are unaware of how photoreceptors work. The beauty of a sunset, a disgusting a slimy mold, the face of a loved one.. all these images trigger emotional responses even beyond the sight, but it […]

Fluorescence is a relatively new character on the stage of science, but the history of fluorescence goes back 500 years! Even then, the property itself is not a man-made invention. Fluorescence is a naturally occurring feature of many minerals, plants, and even animals. Here we will see how the first observations of fluorescence slowly gave

There is piezoelectricity in the human body, making pressure signals turn into electrical signals. In many ways this is a main source of biofeedback in the body. For example, impact on bones is transformed to an electrical signal that triggers fortification of bone material. We will see 7 examples like this here, and it will

Magnetism : the force that can be felt but not seen. Magnetism is a property of a material, caused by electron states. It can change depending on ambient conditions. Some materials, like nickel and cobalt, are nearly always magnetic (having unpaired electrons). Other materials can have induced properties of magnetism by being in an electromagnetic

What would it mean if there was piezoelectricity in the pineal gland? It would mean ambient electromagnetic fields could affect our circadian rhythms. When pressure is applied to piezoelectric crystals, they conduct electricity. The piezoelectric effect is reversible too, so in presence of electric current the crystal will deform on small scales. The pineal gland
