By Maia Dawson '23 In the Lunar lab on the third floor of the Exley Science Center, Thomas Davoren MA ’22, thumbed through scientist David Walker’s handwritten notes from 1970, and inspected samples retrieved from the moon in 1969. Found in Davoren’s work are clues to the origins of Earth’s glowing satellite. Davoren was among the students awarded a Fall 2021 NASA Connecticut Space Consortium Fellowship. In a paper written for a conference in 2020 in Houston, Davoren detailed his discovery of Chromite-Ulvöspinel-Pyroxene (CUSP) inclusions. These unique, microscopic crystalline structures appeared first to Davoren in basaltic rocks retrieved from the…

A team of researchers at Wesleyan has discovered new strains of bacteria—located on the University's campus—that may have the ability to break down microplastics and aid in the world's ongoing plastic waste crisis. Microplastics, which measure less than .20 of an inch, enter the ecosystem— and our bodies— largely through the abrasion of larger plastic pieces dumped into the environment. According to a study published in the Journal of Environmental Science and Technology, the average person consumes at least 50,000 particles of microplastic a year and inhales a similar quantity. "Plastic is typically classified as a non-biodegradable substance. However, some…

On March 30, more than 150 students gathered outside Usdan University Center for a community vigil to mourn the victims of the March 16 Atlanta spa shootings and to create a safe space for Asian and Asian-American students to discuss the rise of anti-Asian violence and be heard by the community. The vigil was organized by Emily Chen ’23, Kevin Le ’22, and graduate student Emily Moon, in conjunction with members of the Asian American Student Collective. Students read poems, played music, and shared their reflections during the event. Towards the end, the organizers gave anyone moved to speak the…

On Nov. 23, the Geological Society of America's (GSA) Geobiology and Geomicrobiology Division awarded earth and environmental sciences graduate student Yu Kai Tan '20 with a student presentation award. Tan presented his poster, "Freshwater Mussels in North America: Museum Collections and Pre-Industrial Biogeography," on Oct. 29 during the GSA's annual (virtual) meeting. Andy (Dick Yee) Tan '21 collaborated with Tan '20 on the poster. Their advisors are Ann Burke, professor of biology, and Ellen Thomas, Harold T. Stearns Professor of Integrative Sciences, Smith Curator of Paleontology of the Joe Webb Peoples Museum of Natural History, and University Professor in the…

Four faculty, two alumni, and one graduate student participated in the virtual Society for Ethnomusicology Annual Meeting held Oct. 22–31. As part of a panel addressing contemporary musical issues in Iran, Bridgid Bergin MA '17 spoke about the Iranian Female Composers Association (IFCA), which was established in 2017 by three female-identifying Iranian composers: Anahita Abbasi, Niloufar Nourbakhsh, and Aida Shirazi. IFCA supports Iranian female-identifying composers by encouraging organizers and ensembles in Iran and beyond to commission and engage these composers in collaborations, while also discovering and mentoring young female composers who are fighting against all odds to become contemporary classical…

Wesleyan students, graduate students, and recent alumni will present research posters during the annual Geological Society of America meeting Oct. 26–30. The virtual event will allow for a five-minute presentation followed by a five-minute period to answer questions. Earth and environmental sciences graduate student Yu Kai Tan '20 and Andy (Dick Yee) Tan '21 will present their poster, titled "Freshwater Mussels in North America: Museum Collections and Pre-Industrial Biogeography," at 5:15 p.m. Oct. 29. Their advisors are Ann Burke, professor of biology, and Ellen Thomas, Harold T. Stearns Professor of Integrative Sciences, Smith Curator of Paleontology of the Joe Webb…

On Sept. 23, two students from the Music Department kicked off the 2020–21 Wesleyan Music Graduate Series, which is being hosted on YouTube this semester. Hosted by Wesleyan’s Music graduate students, this series showcases the performance, compositional, and research capabilities of Wesleyan graduate music students, alumni, and other Wesleyan affiliates. Panels will be streamed in six weekly installments on Wednesdays at 8 p.m. during September and October 2020.

Wesleyan faculty frequently publish articles based on their scholarship in The Conversation US, a nonprofit news organization with the tagline “Academic rigor, journalistic flair.” In this article, Fred Cohan, professor of biology, Huffington Foundation Professor in the College of the Environment, PhD student Kathleen Sagarin, and Kelly Mei ’20 explain how viruses like coronavirus—and several others over history—spread from animals to humans, what determines the size of the outbreak, and how behavioral modifications and technology can stop the spread. A clue to stopping coronavirus: Knowing how viruses adapt from animals to humans As the novel coronavirus death toll mounts, it is…

On Nov. 1, neuroscience and biology BA/MA graduate student Helen Karimi presented a Graduate Speaker Series talk titled "All good things come in pairs: Uncovering the activity of BcnI through co-localization microscopy." Karimi's talk focused on restriction endonucleases (REases), a large family of enzymes that make sequence-specific cuts in DNA. As her abstract details, type IIP REases usually cleave sequences as homodimers. However, BcnI, an enzyme belonging to this subtype, acts in a different way. Karimi's work aims to observe the fine details of BcnI’s cleavage mechanism by using Total Internal Reflection Fluorescence (TIRF) microscopy, an imaging technique in which…

A paper written by Associate Professor of Molecular Biology and Biochemistry Rich Olson and his former students was designated as an "Editor's Pick" by the Journal of Biological Chemistry. Only 2% of the approximately 6,600 papers published each year in the journal receive this designation. Titled "The 1.9 Å crystal structure of the extracellular matrix protein Bap1 from Vibrio cholerae provides insights into bacterial biofilm adhesion," the paper, published on Oct. 4, explores how bacteria "glues" itself to surfaces in the environment. The co-authors include Alison Biester '19, Ethan Chupp '18, Jianyi Lu '17, Charlie Visudharomn '17 and Katherine Kaus PhD…
