In this issue of The Wesleyan Connection, we speak with Taylor Goodstein from the Class of 2014. She is delivering a WESeminar at Reunion & Commencement on the topic of her capstone project: “Looking Inward: Examining the Broken Brain and Reducing Stigma.”

Q: Taylor, what is your major, and how did you settle on this topic for your thesis?

A: I am a neuroscience and behavior and biology double major, and I am also obtaining a certificate in creative writing. I was never planning on writing a thesis because I don’t conduct research in a neuroscience or biology laboratory, but then one day the idea just sort of came to me. I realized how neuroscience classes at Wesleyan focus so much on the hard science, and it becomes easy to forget that the illnesses and disorders that are discussed at a physiological level have real-world social and personal implications. I wanted to explore the human side of neuroscience, and I was inspired by writers who have done the same thing, such as Oliver Sacks. Combining narrative and current neuroscience research is an excellent tool for increasing understanding and reducing the stigma of mental illness, and I wanted to try it out.

Q: Please tell us about the people you interviewed for your project.

A: I interviewed six people, including one Wesleyan student with multiple sclerosis—whose story illustrates how living with an invisible, inconsistent disability can be hard to explain and thus causes lots of misunderstanding—as well as another Wes student who talked about living with an anxiety disorder that perpetuated an eating disorder. Her story was very valuable to me because she has since made a full recovery, and I really went in to detail discussing the aspects of her environment that made it easy for her to seek help and get treatment. Hopefully, such environments can be replicated more and more so people don’t remain silent about mental illness.

Barth, Alumni Co-Author Paper on Preschoolers’ Trust

Hilary Barth, associate professor of psychology, associate professor of neuroscience and behavior, is the co-author of of “Preschoolers trust novel members of accurate speakers’ groups and judge them favorably,” published in the Quarterly Journal of Experimental Psychology, Issue 67, pages 872-883, in 2014. The paper is based on work from BA ’08/MA ’09 student Keera Bhandari’s thesis, and research by former undergraduates Kyle MacDonald ’10 and Jenn Garcia ’10, and former lab manager Elizabeth Chase.

It is known that by age 3, children track a speaker’s record of past accuracy and use it as a cue to current reliability. Through two different experiments, the Wesleyan researchers explored whether preschoolers’ judgments about, and trust in, the accuracy of a previously reliable informant extend to other members of the informant’s group.

In Experiment 1, both 3- and 4-year-olds consistently judged an animated character who was associated with a previously accurate speaker more likely to be correct than a character associated with a previously inaccurate speaker, despite possessing no information about these characters’ individual records of reliability. They continued to show this preference one week later.

Experiment 2 presented 4- and 5-year-olds with a related task using videos of human actors. Both showed preferences for members of previously accurate speakers’ groups on a common measure of epistemic trust. This result suggests that by at least age 4, children’s trust in speaker testimony spreads to members of a previously accurate speaker’s group.

COE, Musician/Fellow Launch Online Environmental Teaching Tool for Kids

College of the Environment fellow Rani Arbo is working with COE Director Barry Chernoff, the Robert Schumann Professor of Environmental Studies, professor of biology, on a project called "Earth Out Loud: Stories from Our Habitat." Earth Out Loud is designed for elementary school-aged children and educators, and offers a short story in audio and/or video format, as well as ideas for exploring the topic further in the classroom or at home.

College of the Environment fellow Rani Arbo is working with COE Director Barry Chernoff, the Robert Schumann Professor of Environmental Studies, professor of biology, on a project called “Earth Out Loud: Stories from Our Habitat.” “Earth Out Loud” is designed for elementary school-aged children and educators, and offers a short story in audio and/or video format, as well as ideas for exploring the topic further in the classroom or at home.

The College of the Environment has teamed up with local singer/songwriter (and mother) Rani Arbo to debut the pilot version of “Earth Out Loud: Stories from Our Habitat” — an educational-but-entertaining online project where second and third graders can hear, explore and respond to stories from their habitat. It uses a straightforward interface to provide accessible audio and video clips for kids and their teachers that relate to their schools’ curriculum in an exciting way.

In the "Earth Out Loud" episode "Radical Raptors," children lean about the great horned owl and ways it adapts to its environment.

In the “Earth Out Loud” episode “Radical Raptors,” children lean about the great horned owl and ways it adapts to its environment.

Arbo, COE director Barry Chernoff and Wesleyan student interns are still brainstorming and developing the content, but the infrastructure is now live and is being built upon.

“It started with a conversation Barry and I were having about science literacy in media and kids, about this time last year,” Arbo said. “I was a science major, and now I have a kid who is happiest outdoors, finding bugs and tadpoles. I’d been wishing he could do more with science in school, but in the younger grades, the focus is really on reading and math. So, Barry and I started talking about an environmental radio show for kids. Something that would help ensnare kids’ imaginations about environmental topics at a young age.”

While the concept still revolves around featuring radio-show-like audio tracks, it’s becoming clear that video may be equally important. So far there’s an episode on raptors and a segment on recycling, available in both audio and video formats. Upcoming episodes will touch upon the nature of bees, soils, and phases of matter, as applied to sweet treats like maple syrup, chocolate and Italian ice.

“If we’re going to make any progress in the world getting an environmental ethic into people, we have to get them excited at a young age,” said Chernoff. “We’re also interested in reaching communities that don’t have a single economic basis or ethnic or social structure — to be able to reach really broad audiences that include both inner city kids and rural kids.”

State Grant will Support Hingorani’s Research on Lynch Syndrome

Manju Hingorani

Manju Hingorani

Manju Hingorani, professor of molecular biology and biochemistry, received a grant worth $324,127 from the State of Connecticut Department of Public Health on May 1.

Hingorani will use the grant to address an important need for new diagnostic technology for Lynch Syndrome (LS), a genetic disorder involving malfunction of DNA mismatch repair, which substantively increases the risk of colorectal, endometrial and other cancers. About 150,000 patients are diagnosed with colon cancer in the U.S. per year, of whom more than one in 35 have LS, and three or more of their relatives are at risk for the disorder (about one in 500 Connecticut residents).

“Early diagnosis of LS can profoundly affect the way in which cancer patients are treated—with respect to surgery, chemotherapy and future surveillance—and provide analogous benefits to their family,” Hingorani explained.

Current validated tests for LS have limitations that lower their feasibility and widespread use in screening at-risk populations.

“Our hypothesis is that the core functions of MMR proteins can be measured directly, quantitatively, rapidly, reliably and at clinically relevant protein concentrations on a nano-structured surface,” she said.

This project, proposed in collaboration by investigators Hingorani and Prabir Patra, assistant professor of mechanical engineering and director of the Biomedical Engineering Program at the University of Bridgeport, is expected to enable development of novel diagnostic nanosensors that will enable substantive advances in the screening, diagnosis and treatment of colorectal and other cancers.

Craighead’s Paper Published in Macroeconomics Journal

Bill Craighead

Bill Craighead

Bill Craighead, assistant professor of economics, is the author of a paper titled “Monetary Rules and Sectoral Unemployment in Open Economies” published in the June 2014 issue of the Journal of Macroeconomics.

Search theory has given us a more realistic mechanism to study unemployment in macroeconomic models. In this paper, Craighead integrated search theory into an “open economy” macroeconomic model – i.e., a model of an economy that interacts with the rest of the world.  One important question in open economy models is what measure of inflation should monetary policy respond to – consumer prices, which include imported goods, or producer prices (the prices of domestically-produced output).  In this model, Craighead shows that monetary policies that focus on producer prices do a better job of stabilizing unemployment.

New Assessment: Climate Change is Here and Now

Gary YoheOn May 6, the Obama Administration released its most comprehensive analysis to date about the impact of the human activity on the climate in the National Climate Assessment, of which Huffington Professor of Economics and Environmental Studies Gary Yohe is vice chair of the Development and Advisory Committee. The report concludes with more certainty than ever that climate change is affecting the daily lives of Americans right now through increases in extreme weather, sea level rise, heat, heavy downpours, drought and other adverse conditions.

PBS Newshour covered the release of the report. Speaking at a press conference at the White House, Yohe said, “What keeps me up at night is a persistence across the population not to recognize that the old normal climate is broken, and we don’t know what the new normal climate is going to be. That lack of recognition and the inability of this community and decision-makers to communicate those risks to individuals unnecessarily puts economic assets at risk, unnecessarily puts human lives at risk, unnecessarily puts ecosystems at risk.”

Yohe also spoke to The Associated Press about the assessment, explaining that this final report is a re-written and shortened version of the draft that was released in January 2013, with more scientific references, reviews by experts and the public, and a thorough review by the National Academy of Sciences. There is even stronger evidence now of climate change than there was in 2013, he said.

And Yohe told NBC News that at a personal level, “…everybody can look out their window and see something about their climate that has changed over the last 5, 10 or 15 years.”

In addition, Mother Jones quotes Yohe as saying: “One major take-home message is that just about every place in the country has observed that the climate has changed…It is here and happening, and we are not cherry-picking or fear-mongering.”

Yohe was also interviewed by Voice of Russia UK radio.

Hughes Receives NSF Grant for Research on Planetary Systems

Meredith Hughes

Meredith Hughes

Meredith Hughes, assistant professor of astronomy, received a grant from the National Science Foundation to support her research on “Dust and Gas in Debris Disks Reveal the Origins of Planetary Systems.” The grant, awarded on April 21, is worth $532,943.

Hughes’ research focuses on understanding the formation and evolution of planetary systems.  She particularly studies the huge disks of gas and dust surrounding a young star, which can give insight into how and when a star planet might form. The disk is made up of  “junk” left over from the star’s formation.

The main technique Hughes uses to observe these circumstellar disks involves collecting radio waves. Invisible to the human eye, radio light allows astronomers to peer into dense dust clouds and trace the motions of small molecules.

Oliver Honored with NIH Award for Protein Translocation Research

Don Oliver

Don Oliver

Professor Don Oliver received a three-year grant from the National Institutes of Health (NIH) Academic Research Enhancement Award (AREA) (R15) for his research titled “Mechanism of SecA-dependent protein translocation.” The grant, worth $374,148, was awarded on April 15.

Oliver is the Daniel Ayres Professor of Biology and professor of molecular biology and biochemistry.

Oliver studies how proteins are targeted to and transported across biological membranes utilizing bacteria as a simple model system.”The current genetic and biochemical studies are designed to elucidate a molecular motor protein, SecA ATPase, that drives proteins through a universally conserved protein-conducting channel by a largely unknown molecular mechanism,” he said.  “Clarification of the transport mechanism by this motor and its interplay with the channel is essential for understanding comparable protein transport systems in higher cells.”

In addition, such studies should allow for the development of novel antibacterial agents against SecA in order to combat the spread of multi-drug resistant bacterial pathogens.

The grant funds will be utilized to support two Ph.D. Students, a BA/MA fifth-year student, and four undergraduate research students that comprise of Oliver’s research group.

NASA Supports Greenwood’s Research on the Moon’s Water

James “Jim” Greenwood

James “Jim” Greenwood

Assistant Professor of Earth and Environmental Sciences James “Jim” Greenwood has received a $331,000 grant from NASA to support his research on the moon’s water.

His proposed research, tracking water in rock samples brought back by the Apollo missions, will “take a giant leap towards solving one of the most important questions in planetary science – whether the Moon is wet or dry,” Greenwood said.

“We’ll be studying pockets of glass trapped in early and late-crystallizing minerals in lunar mare basalt samples,” Greenwood said. “We will measure water and other volatile elements in these trapped melt pockets to reconstruct the volatile history of the samples as they cooled and crystallized near the lunar surface.”

The NASA grant is part of NASA’s Lunar Advanced Science and Exploration Research program.

Greenwood intends to use the grant, which will be distributed over four fiscal years, to fund one Wesleyan undergraduate per summer to conduct research in his lab. The grant will also allow Greenwood to do critical measurement work at Hokkaido University in Sapporo, Japan.

This project is only the latest initiative in Greenwood’s intensive work on lunar rocks, and the Moon’s relative wetness. Most recently he and four colleagues co-authored a paper in the prestigious journal Science, casting doubt on the theory of abundant lunar water, while simultaneously boosting theories around the Moon’s creation, several billion years ago.
