For most terrestrial life on Earth, oxygen is necessary for survival. But the planet's atmosphere did not always contain this life-sustaining substance, and one of science's greatest mysteries is how and when oxygenic photosynthesis—the process responsible for producing oxygen on Earth through the splitting of water molecules—first began. Now, a team led by geobiologists at the California Institute of Technology (Caltech) has found evidence of a precursor photosystem involving manganese that predates cyanobacteria, the first group of organisms to release oxygen into the environment via photosynthesis.

Los Angeles has had bouts of smog since the turn of the 20th century. Angelenos might now be living in a state of perpetual midnight—assuming we could live here at all—were it not for the work of Caltech professor Arie Jan Haagen-Smit.
