Ellen Thomas, professor of earth and environmental sciences and University Professor in the College of Integrative Sciences, recently co-authored five papers in academic journals.
Her first paper, “Jianshuiite in Oceanic Manganese Nodules” co-authored with Jeffery Post and Peter Heaney, appeared within American Mineralogist. Deviating from her usual research, Thomas focused on mineralogy and, in particular, the crystal structure of a rare mineral found in sediments during an ancient counterpart of future global warming.
Thomas co-authored “Variability in Climate and Productivity during the Paleocene-Eocene Thermal Maximum in the Western Tethys,” with Flavia Boscolo-Galazzo and Luca Giusberti, both of the University of Padova. This paper, more in line with her usual research, examines unicellular organisms of the deep sea floor that suffered extinction due to a prior period of global warming. It appeared in Climate of the Past.
Working once again with Boscolo-Galazzo and Giusberti and several other scholars, Thomas co-authored, “The Planktic Foraminifer Planorotalites in the Tethyan Middle Eocene” in the Journal of Micropaleontology. This paper describes the researchers’ use of stable isotope analysis to distinguish between floating planktonic matter from bottom-dwelling foraminifera. Through this analysis, they discuss environmental changes during a relatively period of global warming that took place between approximately 9 and 40 million years ago.
“Late Paleocene-Middle Eocene Benthic Foraminifera on a Pacific Seamount (Allison Guyot, ODP Site 865):Greenhouse Climate and Superimposed Hyperthermal Events,” appeared in Paleoceanography. It discusses deep-sea faunas during the same period in the article from the paragraph above. The two other authors of the paper were mentored by Thomas and briefly visited Wesleyan while under her supervision.
The final paper, “Oxygen depletion recorded in upper waters of the glacial Southern Ocean,” appeared in Nature Communications. This paper documents Thomas’s collaborative research with several scholars and PhD students on Antarctic environments during the last few ice ages. In particular, their work focuses on benthic foraminifera, and chemical analysis of their shells.

Wesleyan’s Van Vleck Observatory is celebrating its centennial this spring, with a series of events and an exhibition beginning in early May.
On May 6, the observatory’s library will reopen to the public with an exhibition on the history of astronomy at Van Vleck. Developed by a team of faculty, students, and staff, the exhibition will use the observatory’s extensive collection of scientific instruments, teaching materials, photographs, drawings, and correspondence to illustrate both the changes in astronomical research and teaching over the past century, and the observatory’s consistent mission of conducting instruction and research under the same roof. The exhibition will incorporate the history of science into Van Vleck’s existing public outreach programs through period lectures, demonstrations of historic artifacts, and gallery talks.
The exhibition was spearheaded by Roy Kilgard, support astronomer and research associate professor of astronomy, Seth Redfield, associate professor of astronomy, associate professor of integrative sciences, Amrys Williams, visiting assistant professor of history, and Paul Erickson, associate professor of history, associate professor of environmental studies, associate professor of science in society.
More events are planned in the run-up to the exhibition opening. On May 1, the Wesleyan Orchestra will hold a concert featuring astronomically themed music, including John Cage’s Atlas Eclipticalis, which was composed using star charts from the Van Vleck Observatory library. On May 3, Special Collections & Archives will host an exhibition, “A Stellar Education: Astronomy at Wesleyan, 1831-1916.” Located on the first floor of Olin Library, the exhibition documents the study of astronomy at Wesleyan from the university’s opening through the construction of the Van Vleck Observatory. On May 4, the History Department is hosting David DeVorkin, senior curator at the National Air and Space Museum, who will give a talk situating Van Vleck in the history of American observatories.

Award-winning science fiction writer Jack McDevitt MALS ’71 received an out-of-this-world honor: Lowell Observatory astronomer named an asteroid for him.
In an e-mail, astronomer Lawrence Wasserman, explained, “I discovered the books of Jack McDevitt early in 2015 and spent most of the year plowing through every novel he has written. I was especially taken by his naming the first Mars spaceship for Percival Lowell, our founder. And, as a person who spent their teens in the ’60s reading Isaac Asimov and Arthur C. Clarke, I was very pleased to find someone who writes science fiction that doesn’t have any elves, dwarfs, or magic swords but gets back to spaceships and time travel.”
Wasserman, who notes his specific interest in asteroids and the Kuiper Belt (a region of the solar system beyond Neptune’s orbit that contains many small orbiting bodies), has discovered around 50 asteroids.
“The International Astronomical Union regulates the naming of these objects (they’re the same ones who demoted Pluto),” he says. “The rules say that the discoverer gets to name the asteroid and that becomes the official name for all astronomers to use.”
Wasserman had named asteroids in honor of his parents, son, and high school physics teacher. Then, “Since Jack McDevitt chose to honor our observatory’s founder, Percival Lowell, in one of his books, I wanted to return the favor and name an asteroid for him.”
The astronomer and the author have exchanged a few e-mails. Wasserman sent McDevitt a photograph of asteroid Jackmcdevitt, as well as one of the asteroid Larissa, which was mentioned in McDevitt’s novel, Coming Home, set in the 12th millennium.
McDevitt, whose newest novel, Thunderbird, was released in December, adds: “Professor Wasserman sent me a list of names provided for asteroids during the past two months. They included mostly scientists, a few literary characters out of Greek mythology, some historical people, a few cities, Tina Fey, Gloria Steinem, Betty Friedan. And, finally, me. They’ve put me in pretty decent company.

A PhD candidate in chemistry will spend two years in Germany working on microwave spectroscopy research.
As a recipient of the prestigious Alexander von Humboldt Research Fellowship, Dan Obenchain will continue his studies at the University of Hanover. He will start his fellowship in August 2016 after taking two months of intensive German language classes.
The Alexander von Humboldt Foundation brings young and senior scientists from around the world to Germany to conduct research in many different fields of science.
“Thankfully, working at Wesleyan has given me many great opportunities to publish my work. The faculty of both the chemistry and physics departments have been very supportive throughout my time at Wesleyan,” Obenchain said.
At the University of Hanover, Obenchain will work alongside Jens-Uwe Grabow, a professor from the Institute of Physical Chemistry and Electrochemistry. Both Obenchain and Grabow are microwave spectroscopists who study the properties of molecules by observing how they rotate. In 2015, Obenchain wrote a research proposal that looks at the interaction of two metals found in bimetallic nano-particles. Nano-particle research is a growing field of materials science, and is helping to make advances in many fields, including fuel cell efficiency and in polymer synthesis.
“Thinking about what we do is similar to thinking about a figure skater spinning in place. The skater will go faster if they bring their arms into their body, and slower if they extend them out. We use the same ideas when molecules rotate to determine their shapes and the type of chemistry they can do,” Obenchain explained.
In addition to having similar research interests, Obenchain and Grabow also design and maintain their own research instruments. Wesleyan’s Machine Shop constructed Obenchain’s microwave spectrometer, which mimics Grabow’s design in Germany.
“Jens is not only a great scientist, he’s the best at designing and building microwave spectrometers,” Obenchain said. “I am more of a MacGyver when it comes to the instruments, while Jens is more of a Michelangelo. Hopefully, I can gain some of his expertise as one day I’d like to start my own academic research lab.”
Obenchain, who is completing his fifth year at Wesleyan, plans to defend his thesis at the end of the month and graduate in May. In addition to his research in Hanover, Obenchain looks forward to exploring Germany “and experiencing its culture, and hopefully seeing a Bundesliga soccer match at some point.”
After completing his fellowship, Obenchain will join more than 27,000 Humboldt Foundation alumni worldwide – the Humboldtians.
