Most biochemical reactions, as studied in the test-tube, involve transactions of infrared quanta rather than light. This is one reason why the importance of light in the living being is still not generally recognised in the West. It is a different story in Russia, where they
have benefited from the work of Alexander Gurvich—a scientist who in due course will be counted as one of the world's great names in biology. As far back as the 1920s, he discovered that dividing cells produce an ultra-weak light radiation (now termed biophotons) which could stimulate mitosis in resting cells. Even then, it was clear to Gurvich that this light constituted an information-bearing signal. This finding lent support to his field theories of biological organisation—theories which had come so long before their time.
