UMD: Carnegie’s Bardyn on comet dust

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.

Exciting upcoming events at the Smithsonian

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.

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.

The biology of Trichoplax adhaerens and how it relates to the evolution of Metazoa

Carolyn Smith

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.

Seneca quarry tour

Mar 17

Atlas Obscura Society D.C.: The Ruins of Seneca Quarry, March 2018

Event Information


Hike into geological, architectural, and presidential history at Maryland’s lost Seneca Quarry with celebrated author Garrett Peck.

On this 2.5-hour walking tour, we’ll make our way along unpaved trails to view the ruins of Seneca Quarry, notable for producing the distinctive red sandstone used for the Smithsonian Castle and many other D.C. buildings. The site was a focal point in a presidential scandal when the questionable business practices of the quarry’s owners embroiled President Grant in what became known as the Seneca Stone Ring Scandal.

Tyrannosaurus rex is arguably the most famous of all dinosaur species. Since its naming in 1905, it has been a cultural and scientific icon. But new discoveries continue to be made about this last and (presently) largest of the giant carnivorous dinosaurs. New specimens and new analytical techniques have revealed details previously unknown about its biology. How did it feed? How did it move? Was it scaly, fuzzy or both? How much and how fast did it grow? How long did it live? And what were those little arms for, anyway? Dr. Holtz will discuss new insights into the biology of T. rex, as well as some of the geological evidence concerning the great extinction which ended the reign of the Tyrant King.
