| A NanoSIMS analysis of the Bitter Springs sample shows the correspondence of carbon and nitrogen concentrations, suggesting the presence of a cell wall. Study was done on the Cameca NanoSIMS 50 instrument in the National Museum of Natural History in Paris in collaboration with Dr. Francois Robert, head of the Laboratory for the Study of Extraterrestrial Materials (LEME), and French colleagues in LEME.
