Decades of obsidian provenance studies have been conducted in different areas of northwestern Iran. Unlike other parts of northwestern Iran, there have been no obsidian studies in the Little Zab basin. Despite the importance of this basin, only a limited number of excavations and archeological studies in this area have been conducted. The artefacts in the present study came from Rick Abad and Ubaid, sites along the Iran-Iraq border. All of the artefacts were discovered to be from sources in Turkey and none from Armenia. It seems that the cultural transformation taking place in the Little Zab basin had almost no effect on the interaction areas and exchange routes in the western part of Lake Urmia which connected to Anatolia, or the roads extending westward into Iraqi Kurdistan and northern Mesopotamia.

The dynamics of a cell is always changing. Cells move, divide, communicate, adapt, and are always reacting to their surroundings non-synchronously. Currently, single-cell metabolomics has become the leading field in understanding the phenotypical variations between them, but sample volumes, low analyte concentrations, and validating gentle sample techniques have proven great barriers toward achieving accurate and complete metabolomics profiling. Certainly, advanced technologies such as nanodevices and microfluidic arrays are making great progress, and analytical techniques, such as matrix-assisted laser desorption ionization (MALDI), are gaining popularity with high-throughput methodology. Nevertheless, live single-cell mass spectrometry (LCSMS) values the sample quality and precision, turning once theoretical speculation into present-day applications in a variety of fields, including those of medicine, pharmaceutical, and agricultural industries. While there is still room for much improvement, it is clear that the metabolomics field is progressing toward analysis and discoveries at the single-cell level.
