Scientists realize one of the most elementary and oldest 'gedanken' experiments in modern physics, namely, excitation of a single molecule with a single photon.

In the beginning was the Sound. The big bang. From that event more than 13 billion years ago, science tells us, the universe rapidly expanded and cooled enough that its white noise of energy could change into subatomic particles. Those particles later joined to form atoms, and those atoms combined to form molecules, eventually leading to the emergence of life. Biochemists are researching what harmonious chemical conditions might have led to the emergence of life.
