The dust of comet 67P/Churyumov-Gerasimenko
After a 10-year journey, the European spacecraft Rosetta arrived at comet 67P/Churyumov-Gerasimenko (67P) on August 6, 2014. In order to conduct intensive research for 26 months, a total of 21 instruments were on board the Rosetta orbiter and the Philae lander. The mass spectrometer named COSIMA (Cometary Secondary Ion Mass Analyzer) was one of the orbiter instrument and was designed to collect cometary dust particles ejected from 67P nucleus, imaged them and analyzed in situ their composition. I will present the Rosetta space mission, as well as results from the COSIMA instrument regarding the organic content of the cometary dust particles.
April 10: Award-winning author and curator Lance Grande will give a deeper understanding of the critical role of curators and how fossils, gems, and other natural objects are found. Moderated by paleontologist and Sant Director of the National Museum of Natural History, Kirk Johnson. https://s.si.edu/2pZOGqA
April 16: From the Hope Diamond to the Blue Flame, geologist Jeffrey Post will give a talk on the science behind the world’s blue natural wonders, and bring out some of the gems and minerals from NMNH’s collection. https://s.si.edu/2pXF9Bi

The biology of Trichoplax adhaerens and how it relates to the evolution of Metazoa
National Institute of Neurological Disorders and Stroke,
National Institutes of Health, Bethesda, MD
Trichoplax is a unique example of an animal that locomotes to find food despite lacking muscles or a nervous system. It is a small, ciliated marine animal that glides on surfaces feeding upon microalgae and cyanobacteria, which it digests externally. It has only six cell types, each with a phenotype and function variably homologous to a cell type present in complex animals. However, Trichoplax relies only on primitive modes of intercellular communication to coordinate the activity of its cells for directed movement and feeding. Similar cell types and simple modes of intercellular communication may have been employed by Proterozoic ancestors of the Metazoa.
Non-Smithsonian visitors will be escorted from the Constitution Ave. entrance of the NMNH to the Cooper Reading Room at 6:50 and 6:55 p.m. Society members will host the speaker for dinner at the Elephant & Castle (1201 Pennsylvania Ave.) prior to the meeting. Members may meet at the restaurant or inside the Constitution Ave. entrance of the NMNH at 5:00 and walk to the restaurant as a group. Parking is available in the west side parking lot of the NMNH. http://nmnh.typepad.com/paleontological_society.
