Diatoms are tiny improbabilities in the vast cosmos. They are tiny marine algae that produce some 20% of the planet’s oxygen and hundreds of their genes have been acquired from bacteria. Each day, about half of this enormous interconnected ecosystem of diatoms gets preyed on by bacteriophage viruses and, in doing so, organic molecules are recycled into the oceans. The silica cell wall of the diatom is a photonic crystal with a complex geometric array of pores which act like a transistor or a diffraction grating in moderating light waves in a quantum manner.
