Mission statement from Sigma Xi CEO Jamie Vernon on January 20,
Sigma Xi’s promise to society is to improve the human condition by
supporting a strong, ethical research enterprise and sharing the fruits of
scientific research with the public. We exist to ensure that the steady
progression of science creates opportunities to address other challenges
facing humanity. To do so, we depend on strong, ethical leadership at the
highest levels of government.

Dr. Anne McNeil (U-M Chemistry Dept)
2021 [Virtual] Speaker: Naomi Levin (Department of Earth and Environmental
"Rift basins, volcanoes and hominin diversity in Pliocene Ethiopia"
Dr. Levin gave an excellent lecture about her recent work in Ethopia on
hominins during the early Pliocene period. "A 3.8-million-year-old
fossil from Ethiopia’s Afar region reveals the face of Lucy’s
ancestor. U-M geologist Naomi Levin coordinated environmental
reconstructions at the site."
Dr. Levin gave her talk virtually on May 5, 2021.
After Dr. Levin's lecture, new members of the chapter were introduced.
New member initiation and annual dues were again supported by
a generous donation to honor the memory of Harold Zepelin, a Sigma Xi
member who sadly died in 2006.
As we have been doing for the past seven years, the University of
Chapter of Sigma Xi provided financial support for support for one of
the UM Museum of Natural History's Science Cafés. Owing to the pandemic,
the last café was on November 14, 2018 on "Cyanobacteria:
Toxic tide or treasure?". The speakers were Vincent Denef
(UM Department of Ecology and Evolutionary Biology) and Anthony
Vecchiarelli (Department of Molecular, Cellular, and Developmental
Biology). We learned that cyanobacteria can be a hazard to health but that
they also absorb CO2 and might affect or even mitigate global warming.
Attendees had lots of questions!
