Ellen Thomas, University Professor in the College of Integrative Sciences and research professor of earth and environmental sciences, is a co-author of a paper titled “Very Large Release of Mostly Volcanic Carbon During the Paleocene-Eocene Thermal Maximum,” published in the weekly science journal Nature on Aug. 31.
The study focused on Palaeocene–Eocene Thermal Maximum, a surface warming event associated with ecological disruption that occurred about 56 million years ago, releasing a large amount of carbon. The researchers combined boron and carbon isotope data in an Earth system model and found that the source of carbon was much larger than previously thought.
Most of the carbon, Thomas and her colleagues discovered, was probably released by volcanism during the opening of the North Atlantic Ocean when Greenland separated from Europe.
The paper also was cited in another Nature article, on PhysOrg and on Science Daily.
Associate Professor of Economics Abigail Hornstein’s article, “Words vs. actions: International variation in the propensity to fulfill investment pledges in China,” was published in the journal China Economic Review in July 2017.
Hornstein studied whether companies from certain countries were more likely than others to fulfill investment pledges. On average, she found that firms fulfilled about 59 percent of their pledges within two years. This number was lower for firms in countries with greater uncertainty avoidance, power distance, and egalitarianism; and higher for those in countries that are more traditional. She also found that popular attitudes toward China did not affect the likelihood of fulfilling investment pledges.
Psyche Loui, assistant professor of psychology, assistant professor of neuroscience and behavior, assistant professor of integrative sciences, is the author of a new publication on musical anhedonia—the lack of pleasure from music. Together with others in her lab, Loui studied an individual with musical anhedonia and compared his brain against a group of controls. They found that his auditory cortex was differently connected to his reward system, a finding which gives further support for the role of brain connectivity in the musical experience.
The article, titled, “White Matter Correlates of Musical Anhedonia: Implications for Evolution of Music,” was published Sept. 25 in Frontiers in Psychology. It was coauthored by Sean Patterson, BA ’17, MA ’18; Tima Zeng ’17; and Emily Przysinka, former lab manager in Loui’s lab.
Logan Dancey, assistant professor of government, and Jasmine Masand ‘15 are the co-authors of “Race and Representation on Twitter: Members of Congress’ Responses to the Deaths of Michael Brown and Eric Garner,” published in Politics, Groups, and Identities in July 2017.
This paper investigates the public responses of members of Congress to the deaths of Michael Brown and Eric Garner and the subsequent protests and grand jury decisions. To do so, the authors examined members’ engagement with the issue on Twitter, which became a platform for public protest with such hashtags as #BlackLivesMatter and #ICantBreathe.
“We find that a member’s race is a more robust predictor of their engagement on the issue than is the member’s partisanship or the partisan and racial demographics of their district,” Dancey explained. “By showing that descriptive representation may overwhelm more traditional notions of district-based representation in responses to a racially charged issue, we further highlight the role descriptive representation in Congress plays in ensuring that the diversity of voices coming out of Congress reflects the diversity of voices in the public at large.”
Joseph Knee, the Beach Professor of Chemistry and Dean of the Natural Sciences and Mathematics Division, is the author of a new article published in the journal Physical Chemistry Chemical Physics (PCCP). This “Perspectives” article, which was commissioned by the PCCP editorial board and editorial office, is a high-profile look at work by Knee and his collaborators that has been going on for nearly a decade. Perspectives articles are intended to present an authoritative state-of-the-art account of a particular research field.
The research by Knee and his collaborators, which is ongoing, uses experimental and computational methods to explore hydrogen bonding interactions, which are extremely important in the structure of water, various solutions, and in many key biochemical structures and processes.
Knee explains, “The most important aspect of our methodology is making careful experimental measurements of two single molecules forming hydrogen bonds and then modeling these bonds with modern quantum chemical calculations. The calculations allow us to decompose the various forces which contribute to the bond strength and structure. The larger goal is to generalizing this insight to more complex hydrogen bonded systems, particularly hydrogen bonding networks which exist in liquids and biological systems.”

A team of scientists from Wesleyan discovered three super-Earths transiting around a nearby star, 98 light-years away. The NASA-generated image above depicts a different super-Earth: 55 Cancri e, discovered in 2004.
A team of scientists from Wesleyan, led by Associate Professor of Astronomy Seth Redfield and graduate student Prajwal Niraula MA ’18, has co-authored a paper on the discovery of three planets, or super-Earths, transiting around a nearby star, just 98 light-years away.
“Super-Earths are slightly larger than Earth, and the three of them straddle the divide between the rocky planets like Earth and ice giants like Neptune,” explains Redfield.
These planets were found using the Kepler Space Telescope. “Kepler has found thousands of exoplanets these last eight years, but this is the closest planetary system that Kepler has ever found, although closer planetary systems have been found using different telescopes,” says Redfield.

Three scholars from the Molecular Biology and Biochemistry Department are co-authors of a study published in The Journal of Biological Chemistry in August 2017. The paper is titled “Linchpin DNA-binding residues serve as go/no-go controls in the replication factor C-catalyzed clamp loading mechanism.”
The co-authors, Manju Hingorani, chair and professor of molecular biology and biochemistry, professor of integrative sciences; Juan Liu, research associate; and Zayan Zhou, PhD ’13, performed the study on Replication Factor C (RFC) and proliferating cell nuclear antigen (PCNA), which are two essential proteins required for DNA replication and repair in all living organisms.
The researchers found new mechanistic information about how different parts of the RFC protein work together to load PCNA onto DNA (by “clamp loading”), which allows PCNA to help dozens of other proteins to replicate and repair DNA.
The Hingorani group investigates proteins responsible for DNA replication and repair. These proteins maintain genome and cell integrity, and their malfunction leads to cancer and other diseases.
Ethan Kleinberg, director of the Center for the Humanities, is the author of Haunting History: For a Deconstructive Approach to the Past, published by Stanford University Press in August 2017.
“Haunting History is about the ways we think about the past and ‘do’ history at a moment when the digital revolution is changing how we conduct research, store materials, and even write,” Kleinberg said. “In it I argue that many of strategies for writing about, but also understanding the past, are conditioned by the analog practices of the previous century which has served to create the illusion that the past can be studied like an object held in your hand or placed under a microscope.”
The past — by definition — is gone and thus has no definite properties or perhaps we can say that is has latent properties that are activated when we do history, Kleinberg explained. “But this activation of the past is always partial leaving remains that are hidden or dormant. This is a past that is absent but haunts us and can return in ways that disturb our conventional historical narratives and understanding of what the past and history is.”
To account for this play of absence and presence, Kleinberg advocate for a “hauntological” approach to the past.

A star-studded cast of contributors curated by Shapiro-Silverberg Professor of Creative Writing Amy Bloom ’75 fill the pages of New Haven Noir, featuring original stories from Michael Cunningham, Stephen Carter, Roxana Robinson, Assistant Professor of English Hirsh Sawhney and many others. The book is the latest addition to an award-winning series of original noir anthologies published by Akashic Books, founded by publisher and editor-in-chief Johnny Temple ’88.
“I’m a big fan of noir,” says Bloom, editor of the anthology, which has garnered praise from both Publishers Weekly and Kirkus Reviews. “When Johnny called me and said, I don’t know if you’re from New Haven, but I know you’re connected to New Haven and I’d love you to edit the anthology, I jumped at the opportunity,” she said.
Bloom worked with Temple to select contributors for the anthology, with Bloom choosing to invite several writer friends who hadn’t written noir before, including Alice Mattison and Michael Cunningham. “I told them, it’s conflict and it’s mystery. Bleak. Snappy outfits. Great dialogue,” Bloom said. “And they said, count us in.”
In addition to serving as editor of the anthology, Bloom also is a contributor. Her story, “I’ve Never Been to Paris,” set in New Haven’s East Rock neighborhood, is actually an excerpt from a mystery she wrote years ago, tailored specifically for New Haven Noir.

Hirsh Sawhney, assistant professor of English, is the author of a recent work of fiction titled The Diary of Rehan Malhotra, published as an e-book by Juggernaut Books (2017).
In this timely story, Rehan, the son of a Muslim mother and Hindu father, is a middle-aged high school teacher in New Haven, Conn., who struggles with his growing estrangement from his wife and the affluent, white community in which he lives. A charged encounter with a neighbor causes him to look back on his troubled teenage years, when he used and sold drugs, and when he forged a problematic friendship with a young black man named Ink. The Diary of Rehan Malhotra casts a spotlight on the invisible walls that divide city from suburb, which keep some people safe and others confined. It is a meditation on the possibilities and limitations of literature as a cure for social ills.
The story costs 10 rupees, or 15 cents, and is being published as a part of Juggernaut’s efforts to get inexpensive, quality literature to as diverse a readership as possible.
Sawhney is also the author of South Haven and the editor of Delhi Noir. He also collaborated with Amy Bloom ’75 on New Haven Noir, Hirsh has lived in Delhi, London and New York City.
