Making “gak” at Green Street
Oneiry, in sixth grade and 11 years old, liked the tie-dye experiment, where learning about the light and color also resulted in cool take-home T-shirts. Genesis, a nine-year-old fourth grader, really enjoyed the liquid nitrogen demonstration, especially the ice cream she got to make with it. And Julia, at 10 in fifth grade, had a good time making “gak,” a substance that’s not quite solid and not quite liquid – and slimy and fun.
They were among 10 Middletown girls between fourth and sixth grade who participated in a girls’ science camp sponsored by the Green Street Arts Center Aug. 4-8. The session, staffed by Wesleyan faculty, was designed to introduce girls to the “STEM” fields – Science, Technology, Engineering and Math. Women are underrepresented in these fields, and educators believe it’s important to engage girls in them as early as possible.

Huffington Foundation Professor of Economics and Environmental Studies Gary Yohe responded to a new study which predicted the Keystone XL Pipeline could produce carbon emissions as high as four times the level previously stated by the U.S. State Department. The earlier estimates didn’t take into account the downward pressure the pipeline would put on fuel prices, if approved, spurring greater fuel consumption and increasing pollution.
Lower fuel prices may sound like a good thing, Yohe told The Associated Press, but there’s no such thing as a free lunch.
“Lower fuel prices are bad if they don’t include all of the social costs,” he said. “Consumers are happy, but the planet is not necessarily.”
Yohe is also chair of economics.
This NASA image shows a solar storm in early 2012.
A July NASA report that a huge solar storm narrowly missed Earth in 2012 – avoiding catastrophic damage to energy, transportation and communications systems – has caused a media stir and some worry among Earthlings.
What’s more, other recent reports say that Earth is overdue for a devastating storm of the kind known as a “Carrington event” after an 1859 storm that disrupted telegraph signals and caused other damage in a still-nascent industrial world. Named for 19th-century English astronomer Richard Carrington, it was the largest of its kind on record. A similar event now, in a world dependent on digital communications and electrical energy, would cause widespread, long-lasting power outages and disrupt transportation and communications planet-wide. Eric Mack, a science blogger for Forbes, referred facetiously to a reversion to “Amish-style” civilization.
Seth Redfield, assistant professor of astronomy, says the recent near-miss isn’t a cause for worldwide freakout, but should be a wake-up call; while a catastrophic solar storm may be several generations away, “it’s going to happen,” and scientists should be working on ways to better predict the event.
“I think it’s really important for us to understand what’s going on and have some good perspective on that because if we don’t prepare for it, we’re going to suffer the consequences,” he said. “We don’t need a Manhattan-style project and (to) devote 10 percent of our GDP to this one. But we do need to pay attention.”

Psyche Loui, assistant professor of psychology, assistant professor of neuroscience and behavior
Many of us have experienced an intense emotional and physical sensation while listening to a particularly moving piece of music–often described as a thrill, chill or goosebumps. In a new article published in Frontiers in Psychology, Psyche Loui, assistant professor of psychology, assistant professor of neuroscience and behavior, and psychology major Luke Harrison ’14 integrate the existing multidisciplinary literature to create a comprehensive, testable model of “transcendent psychophysiological moments in music.” The paper came out of Harrison’s final paper in Loui’s course on Music Perception and Cognition.
They begin by considering the different nomenclature used in popular and academic discourse for this phenomenon, and the advantages and disadvantages of terms such as “thrills,” “chills,” “frissons,” or even “skin orgasms.” They go on to discuss the importance of cultural and social context in explaining musical “frisson,” and the emotional and neurobiological mechanisms behind this sensation. Finally, they explore the specific types of musical stimuli that elicit this reaction.

Water is the most ubiquitous fluid on Earth, and plays a foundational role in life as we know it. And yet the complexity of this seemingly simple molecule remains a vigorously debated area of scientific research to this day. Writing in the most recent issue of Nature Physics, Professor of Physics Francis Starr provides a commentary on recent research to uncover the mystery of water’s unusual properties.
“We all learn as children that oil and water don’t mix,” Starr writes. ” If there was only one fluid – say just the water – then “unmixing” should not even be a possibility. However, it turns out that evidence suggests that, under unusual supercooled conditions, water can unmix from itself, forming two distinct fluids, both of which are pure water. And it turns out this unusual behavior just might help explain many of water’s other unusual and vital features.”
Nature Physics, part of the prestigious group of Nature journals, is published monthly.
Starr’s research at Wesleyan focuses on computational approaches to understand the emergent complexity of soft and biological matter. His lab has explored DNA modeling and nanotechnology, lipid membrane dynamics, and polymer films and composites. Undergraduates and graduate students work together in the Starr lab, emphasizing connections to experimental results.

New students interested in math and the sciences, who want to get a jump start on their college experience, are taking advantage of a new program this summer.
The Wesleyan Physical Sciences and Mathematics Scholars Program will welcome 11 students from the Class of 2018 to campus for its debut summer session July 27-Aug. 1. An additional 11 students will participate online.
“We’re really excited to put this program into place,” said Ishita Mukerji, dean of Natural Sciences and Mathematics. “One common variable among all these scholars is a very strong interest in science.”

Catherine Walsh ’16 handles a young hen July 14 at Long Lane Farm. Chickens are a new addition to the two-acre, student-run farm this summer. The hens will start laying in fall and supply Bon Appétit and Wesleyan’s Dining Services with fresh eggs.
Long Lane Farm is Wesleyan’s student run organic farm devoted to allowing students a place to experiment and learn about sustainable agriculture. This summer, seven students are tending the two-acre farm full-time. New to this year’s farm are Rhode Island red hens, who reside in the farm’s chicken coop. The coop was designed and built by Wesleyan’s Architecture II class in 2013.
Throughout the summer, other students and community members help out around the farm with planting, watering and weeding.
Food harvested from the farm is sold at the North End Farmers’ Market throughout the summer, and at the Wesleyan Farmers’ Market during the academic year. The student farmers donate excess food to Amazing Grace Food Pantry in Middletown, and have an arrangement through which Bon Appétit: dining services funds positions for students to work on the farm in exchange for weekly deliveries of farm vegetables. In addition, the students invite local families to the farm and teach children about the various aspects of farming and producing food. Children are sent home with a bag of produce that they personally harvested.
The farm is funded by the College of the Environment, Bon Appétit and Wesleyan’s Green Fund. View more photos of the farm below: (Photos by Olivia Drake)

The University of Connecticut-Wesleyan University Stem Cell Core was among the recipients of a new batch of state funding granted for stem cell research.
Connecticut Gov. Dannel Malloy on June 24 announced nearly $10 million in new funds to 18 Connecticut-based stem cell researchers. The UConn-Wesleyan Core received $500,000, of which about $25,000 will go to the outreach component of the Core run by Laura Grabel, the Lauren B. Dachs Professor of Science and Society, professor of biology. According to Grabel, the funds will support visits by stem cell researchers to Connecticut colleges and universities. Since its founding in 2006, the UConn-Wesleyan Core has contributed substantially to the Connecticut stem cell initiative by providing a central source of technologies and materials for research on human embryonic stem cells and induced pluripotent stem cells.

Gary Yohe, the Huffington Foundation Professor of Economics and Environmental Studies, was called on by The Associated Press to comment on a new analysis of the regional economic impacts of climate change. The report, commissioned by The Risk Business Project, made predictions including:
Between $66 billion and $106 billion in coastal property will likely be below sea level by 2050, labor productivity of outdoor workers could be reduced by 3 percent because extremely hot days will be far more frequent, and demand for electricity to power air conditioners will require the construction of more power plants that will cost electricity customers up to $12 billion per year.
While Yohe said the report’s general conclusions are “right on the money,” he noted that “There’s a whole litany of things not calculated in the assessment.”
Yohe added that this report is notable because of the business and financial experience of the people behind it, including former New York City Mayor Michael Bloomberg, former Treasury Secretary Henry Paulson, Jr., former hedge fund manager, Thomas Steyer, and former Treasury Secretary Robert Rubin, among others.
“These are people who have managed risk all their lives and have made an enormous amount of money doing so,” Yohe said.
Fifth graders from Snow Elementary School in Middletown toured Wesleyan’s astronomy, biology, chemistry, physics and scientific imaging departments on June 18, 2014. Students also visited the Joe Webb Peoples Museum and Collections in Exley Science Center.
Brian Northrop, assistant professor of chemistry, used the reversible hydration and dehydration of cobalt(II) chloride to demonstrate Le Chatelier’s principle and create color-changing “humidity sensors.” Pieces of filter paper were saturated with a solution of cobalt(II) in water, which turned the paper pink. Warming the paper with a blow dryer evaporated the water and turned the paper blue by re-forming cobalt(II) chloride.
Research student Jesse Mangiardi ’15 Mangiardi ’15 demonstrated how to change the chemical composition — and color — of a penny. First he submerged a copper penny in a solution containing zinc mixed with a base, which coated the penny in zinc and made it appear silver. Next, he heated the zinc-coated penny with a blow torch which caused the zinc and copper to react and form brass, and turned a penny bright gold.
The students took a few silver and gold pennies back with them to Snow School.
