A century ago, when bioscience was in a rudimentary stage and there was no tangible interaction with the basic sciences, an extraordinary biophysicist Jagadis Chandra Bose, demonstrated, with the help of extremely sensitive instrument fabricated by him, that plants are sensitive to light, heat, electric current and any others thus just like a living being. Modern biophysicists started with an enormous amount of possibilities helped by a large number of discoveries on the nature of matter and radiation, together with diverse measuring instruments and concepts. For example, the use of X-ray crystallography to elucidate the structures of biomacromolecules like tobacoo mosaic virus, haemoglobin, myoglobin, DNA and gene. Eminent physicists are trying to find out whether biological events could be explained on the basis of known laws of physics or are hoping to discover new laws. The physicists have thus been able to decipher the genetic code and elucidate genetic information and transfer mechanism and thereby to evolve the new branch of molecular biology. The outcome of the extension of molecular biology to a wider and more expensive domains has led to the evolution of biotechnology. With the help of this versatile discovery newer products in agriculture, medicine and industries have become possible. Our attention has, however, been drawn to the dangers of introducing new products, especially relating to food, unfamiliar to the environment. Some of the stalwarts in the field of molecular biology felt inclined to go over to neurobiology to the study of the brain. With that is associated such concepts as mind and consciousness. Some recent thoughts and concepts on mind and consciousness have been briefly touched upon.
