Photosynthesis has unique isotopic signature
Los Angeles CA (SPX) May 15, 2015
Photosynthesis leaves behind a unique calling card in the form of a chemical signature that is spelled out with stable oxygen isotopes, UCLA geochemists reported April 24 in the journal Science. The findings suggest that similar isotopic signatures could exist for many biological processes, including some that are difficult to observe with current tools. The isotopic signature could be used, for example, to assess the health of oceans, said lead author Laurence Yeung, formerly a UCLA postdoctoral ... read more
