CU Boulder researcher Pedro DiNezio emphasizes solving the problems of climate change in the here and now

When Pedro DiNezio began studying El Niño and La Niña roughly 20 years ago, human-caused climate change was still a future problem. At that time, researchers spent much of their energy trying to show that humans were, in fact, influencing the world’s climate.

Flash forward two decades, and climate change is no longer some far-off, eventual phenomenon—it’s happening now. Communities and businesses are factoring climate change into their yearly, monthly and even weekly decisions.

Against this backdrop, climate scientists are starting to transition away from purely theoretical research and pivot toward more applied work and consulting. DiNezio, a �� associate professor of atmospheric and oceanic sciences, for example, is embarking on a new partnership with WTW, a global insurance broker and risk advisor—an exciting prospect for putting research into practice.

“We can’t stop the drought and the heatwaves, but we can do things to become more resilient, so they don’t affect us as badly—at least for a while,” says Pedro DiNezio, a CU Boulder associate professor of atmospheric and oceanic science.

“I’m going through a career transformation right now because I’m more and more interested in solving problems in the here and now,” says DiNezio. “Because we now know so much about the climate system and about the impact it could have on society, many of us in academia are feeling that it’s time to act.”

Resilience is key

As global temperatures continue to rise, world leaders are taking steps to reduce greenhouse gas emissions. Whether their actions will be enough to stave off catastrophic warming remains to be seen. But, in the meantime, communities and businesses must prepare for and adapt to the unprecedented extremes caused by climate change.

Drought, heatwaves, wildfires, rising sea levels, coastal erosion and other ripple effects are already causing big problems—and scientists like DiNezio might be able to help solve them.

“We can’t stop the drought and the heatwaves, but we can do things to become more resilient, so they don’t affect us as badly—at least for a while,” DiNezio says. “And hopefully we can win that time we need to stabilize the climate.”

For example, research has linked hot weather with an increased risk of accidents and injuries in the workplace. Employees are more likely to suffer heat-related illnesses on hot days. But they’re also more likely to be involved with other seemingly unrelated accidents, too.

From an ethical perspective, companies want to keep their workers safe and healthy. But, from a business perspective, they also want to keep costs down—and workers-compensation insurance is a major expense.

“We’re only starting to learn the full extent of the impact of heatwaves and how we can mitigate them,” says DiNezio. “This is having a huge impact on businesses. So, how do we prevent these accidents?”

As the climate shifts, supply chains are also becoming increasingly vulnerable. When vital waterways like the Panama Canal’s Gatun Lake dry up during droughts, ships cannot reach their intended destinations on time. And those delays cost money.

“You cannot avoid these things, but at least you can know there’s a risk and plan an alternative shipping route,” DiNezio says.

Reinsurance companies are particularly interested in anticipating disasters because they already take a long-term, big-picture view of risk. While a company in one part of the world might be worried about drought and another might be focused on sea level rise, global reinsurance companies see what’s happening around the world and connect the dots.

“Reinsurance companies look for our knowledge because their scale makes them more sensitive to the aggregated effect of climate change over large swaths of the world,” says DiNezio. “They are some of the first businesses to think, ‘How do we anticipate this new climate that is continually changing and prepare for it?’”

Why now?

Climate science is a relatively new field. But, in recent years, it’s matured enough to allow researchers to make predictions that are applicable to communities and businesses.

“We are starting to see these climate events happening, we have the tools to better predict them, and the climate sector is recognizing this as a problem, as a need,” says DiNezio. “As academics, we cannot ignore them because this is no longer a theoretical exercise.”

Teaching has played an important role in DiNezio’s transformation. After joining the CU Boulder faculty four years ago, DiNezio began teaching an introductory-level class on climate change for non-science majors.

Every semester, DiNezio updated the curriculum because the climate was changing so fast. That process has been a bit of a reality check.

“When you talk about it with students, especially non-science majors, they are interested in what effect this could have on their lives and their careers,” says DiNezio. “You have to think about these things more concretely.”

Concrete problems

DiNezio, like other climate scientists who are experimenting with consulting, is approaching this new career chapter with a mix of enthusiasm and anticipation.

“I’m diving into something that I haven’t done before,” DiNezio says. “Sometimes, I describe it to my friend like I’m doing another PhD. … A lot of people in my field are going through this transformation and is entirely new.”

But, in some ways, DiNezio suspects solving real-world problems may be easier than solving theoretical ones. Either way, DiNezio is looking forward to the new challenge.

“When you move away from the purely academic, the problems become really concrete,” DiNezio says. “It’s really simple: How do you prevent heat deaths or help farmers mitigate drought? For me, the new thing is the action. The transformation is, how do we act with all this information about weather and climate? It’s very different from the academic approach. Now, we have a goal.”

Don’t fear the fungi

Don’t fear the fungi Rachel Sauer Thu, 04/17/2025 - 07:30

CU Boulder mycologist Alisha Quandt says there’s little reason to fear a fungi-zombie apocalypse like the one imagined in the HBO hit TV series ‘The Last of Us’

Alisha Quandt prepared herself in advance to be asked by students and others about Sunday’s season 2 premier of “The Last of Us”—the hit HBO series that imagines a post-apocalyptic future where a fungal infection on a massive scale turns the majority of humanity into zombie-like creatures seeking to infect the last pockets of civilization.

It’s not that Quandt is a super-fan of the TV show (“I’m not into zombies, honestly,” she confesses), but as a mycologist—a scientist who studies fungi—she is used to getting asked about the TV show, specifically whether the grim future it imagines is anything people need to be worried about, or whether it’s simply harmless entertainment.

“I’m happy if it gets people excited about fungi. They’re so incredible,” says Alisha Quandt, a CU Boulder assistant professor of ecology and evolutionary biology.

“Especially when the TV show first debuted, it was definitely a topic people wanted to discuss,” says Quandt, a �� Department of Ecology and Evolutionary Biology assistant professor.

“And it seems like the topic (of infectious fungi) comes up in popular culture every five to 10 years. When I was starting my PhD, people were fascinated by the ‘Planet Earth’ TV series by David Attenborough, where this ant infected by Ophiocordyceps unilateralis staggers around, being controlled by the fungus. Then later, the Last of Us videogame came out, which really got people excited about (zombie) fungi.”

Quandt did her PhD research studying Cordyceps-like fungi, which is the type of pestilence the TV show identifies as the culprit for turning civilization into a hellscape populated by zombies controlled by the spiky fungi tendrils sprouting from their heads. For the record, Quandt finds that scenario very unlikely, for a variety of reasons.

No need to panic

For starters, the TV show imagines a worldwide outbreak is caused by Cordyceps-contaminated food. However, Quandt says most fungal infections in humans are caused by inhaling spores or through contact with the eyes or skin—and not through the digestive tract. She notes that in many parts of the world, people have been ingesting Cordyceps fungi for decades without incident, because they believe they contain beneficial properties.

“I’ve eaten Cordyceps in Asia, in Korea and China,” says Quandt, who remains unzombified. “It’s considered a part of traditional Chinese medicine, especially certain species. Even here in the U.S., you can find Cordyceps in coffees and teas, for example. They sell them at stores in Boulder.”

Quandt says another reason not to be overly concerned about Cordyceps is that many of them are “specialists” that have a very narrow range of hosts that they infect, down to a specific family of ant or spider. While some Cordyceps can transition from infecting one type of arthropod to another, or to jump from infecting an insect to another fungus, she says making the leap to a healthy human being is remote.

What’s more, the average human body temperature of 97 to 99 degrees Fahrenheit is not an environment that’s hospitable for many fungi, although Quandt acknowledges there are exceptions. “The Last of Us” imagines a future in which global warming has raised Earth temperatures to a point where mutated Cordyceps zombie fungi could live comfortably in human hosts, but Quandt notes that ambient temperatures of even 90 degrees Fahrenheit are still cooler than the human body.

“That’s a hard path for me to follow,” she says of an environmental change that would allow Cordyceps to evolve in such a way. “There’s a lot of assumptions that would go into that trajectory.”

Beyond those arguments, Quandt says there is an even more important one as to why humans don’t need to start doom prepping for a fungi apocalypse.

“My argument about why we shouldn’t be worried about a fungal pandemic is that our bodies, when fully immunocompetent—meaning healthy human bodies—are extremely well equipped to deal with fungal propagules (spores) that come into contact with our bodies, mostly through our lungs,” she says. “Fungi have this cell wall that is made up of stuff that our bodies do not make. So, our bodies are really good identifying and dealing with that.”

Quant says fungal infections do pose a risk to people whose immune systems are compromised—particularly if they have taken a heavy dose of antibiotics, because those can kill off good bacteria, which can lower resistance to harmful fungi.

“Once our immune system goes away, which could handle those types of (fungi), we have so few antifungal drugs to treat fungal infections compared to the myriad of antibiotics that we have to treat bacterial diseases,” she says.

For the immunocompromised, Quandt says one of the most concerning fungi—which just cropped up in recent years and has spread worldwide—is Candida auris.

“It is a really concerning human pathogen because it is what we call nosocomial, meaning it is hospital related. People get these infections in hospitals, and once it’s in a hospital, it can be almost impossible to get rid of it,” she says.

“People will use all kinds of bleach and ethanol but it’s very hard to get rid of the yeast once it gets into a hospital room. And the fully immunocompetent, like nurses and doctors who are not sick, can end up spreading it from room to room to sick, often elderly, patients. Unfortunately, there’s not a good defense on the ground, so to speak, once Candida auris takes hold.”

But while “opportunistic pathogens” like Candida auris can pose a risk to the immunocompromised, the number of fungal diseases that could be described as “primary pathogens”—meaning they can infect and potentially cause serious health issues for healthy individuals—is less than a handful, Quandt says.

One primary pathogen that can be found in the United State is Valley Fever, which is primarily located in New Mexico, Arizona and southern California. Farming, construction or other practices that disrupt the soil can release the fungi’s spores, which people can then breathe into their lungs. Once inhaled, Valley Fever can potentially cause fever, cough, tiredness, shortness of breath and, in limited cases, serious conditions such as pneumonia and meningitis.

“But those are the rarer things, and I’m still not worried about them becoming common because they’re still not being spread from person to person,” she says.

In contrast with the way “The Last of Us” portrays fungi as an existential threat, Quandt sees a type of virus that’s already well-known to the scientific community and the public alike as a much greater risk for causing a global pandemic. The World Health Organization estimates the COVID-19 pandemic killed 14.9 million people worldwide between January 2020 and December 2021.

“As we’ve recently seen, unfortunately, there are a lot of other places to look for more likely suspects for (global pandemics). Things that were predicted by a lot of great investigative journalists and epidemiologists, like coronavirus and other zoonotic diseases (which jump from animals to humans), pose a much greater threat to mankind,” she says.

“As we’ve recently seen, unfortunately, there are a lot of other places to look for more likely suspects for (global pandemics). Things that were predicted by a lot of great investigative journalists and epidemiologists, like coronavirus and other zoonotic diseases (which jump from animals to humans), pose a much greater threat to mankind.”

And now, back to the show

Even beyond the fact she’s not into zombies, Quandt says her training as a mycologist can get in the way of her enjoyment of “The Last of Us” as entertainment, based upon the few episodes she has watched.

“I’m probably a little too close to watch the show—especially the fruiting bodies,” she says. “Sometimes they would show a person who is dead up against a wall, and the fruiting structures look life shelf fungi,” she says.

“Those are related to mushrooms—they’re not related to (fungi) that are molds, like Cordyceps. The artistry was beautiful, so they did a good job visually, but it’s just completely inaccurate. So, it does take you out of it a little bit to watch as an expert; you have to really suspend belief.”

Another scene that inspired disbelief for Quandt was a flashback episode—prior to the fungal pandemic—when a mycologist in Jakarta is asked by representatives of the country’s military to provide guidance on how to proceed after a group of workers in a building are found to be infected with early cases of the Cordyceps contagion. After surveying the infected, the mycologist gives the military members a chilling one-word answer: “Bomb!” (As in, bomb the entire country to try to prevent the infection from spreading.)

“My husband was watching the show with me. He paused it there and he’s like, ‘What should they do?’ I was like, ‘Get all the antifungals that you can. Get all the major ones and then get the rare ones—and start pumping these people with IVs, or all the people that you think might be exposed and get going on it.’ But the fact she said ‘bomb!’ I almost found it funny, but I was also like, ‘Oh, my God, that’s so dramatic.’ Still, it’s a TV show, and I acknowledge that.”

While Quandt may opt not to watch more episodes of “The Last of Us,” she says if the TV show raises public awareness about fungi—even if the details in the show are not entirely correct—she is all for it.

“I’m happy if it gets people excited about fungi,” she says. “They’re so incredible.”

In the archaeological record, size does matter

In the archaeological record, size does matter Rachel Sauer Mon, 04/14/2025 - 09:24

CU Boulder archaeologist Scott Ortman and colleagues around the world explore relationships between housing size and inequality in PNAS Special Feature

If the archaeological record has been correctly interpreted, stone alignments in Tanzania’s Olduvai Gorge are remnants of shelters built 1.7 million years ago by Homo habilis, an extinct species representing one of the earliest branches of humanity’s family tree.

Archaeological evidence that is unambiguously housing dates to more than 20,000 years ago—a time when large swaths of North America, Europe and Asia were covered in ice and humans had only recently begun living in settlements.

Between that time and the dawn of industrialization, the archaeological record is rich not only with evidence of settled life represented by housing, but also with evidence of inequality.

CU Boulder archaeologist Scott Ortman partnered with colleagues Amy Bogaard of the University of Oxford and Timothy Kohler of the University of Florida on a PNAS Special Feature focused on housing size in the archaeological record and inequality.

In a Special Feature published today in the Proceedings of the National Academy of Sciences (PNAS), scholars from around the world draw from a groundbreaking archaeological database that collects more than 55,000 housing floor area measurements from sites spanning the globe—data that support research demonstrating various correlations between housing size and inequality.

“Archaeologists have been interested in the study of inequality for a long time,” explains Scott Ortman, a �� associate professor of anthropology who partnered with colleagues Amy Bogaard of the University of Oxford and Timothy Kohler of Washington State University to bring together the PNAS Special Feature. (Special Features in PNAS are curated collections of articles that delve into important topics.)

“For a long time, studies have focused on the emergence of inequality in the past, and while some of the papers in the special feature address those issues, others also consider the dynamics of inequality in more general terms.”

Kohler notes that "we use this information to identify the fundamental drivers of economic inequality using a different way of thinking about the archaeological record—more thinking about it as a compendium of human experience. It’s a new approach to doing archaeology.”

Patterns of inequality

Ortman, Bogaard and Kohler also are co-principal investigators on the Global Dynamics of Inequality (GINI) Project funded by the National Science Foundation and housed in the CU Boulder Center for Collaborative Synthesis in Archaeology in the Institute of Behavioral Science to create the database of housing floor area measurements from sites around the world.

Scholars then examined patterns of inequality shown in the data and studied them in the context of other measures of economic productivity, social stability and conflict to illuminate basic social consequences of inequality in human society, Ortman explains.

“What we did was we crowdsourced, in a sense,” Ortman says. “We put out a request for information from archaeologists working around the world, who knew about the archaeological record of housing in different parts of world and got them together to design a database to capture what was available from ancient houses in societies all over world.”

Undergraduate and graduate research assistants also helped create the database, which contains 55,000 housing units and counting from sites as renowned as Pompeii and Herculaneum, to sites across North and South America, Asia, Europe and Africa. “By no stretch of the imagination is it all of the data that archaeologists have ever collected, but we really did make an effort to sample the world and pull together most of the readily available information from excavations, from remote sensing, from LiDAR,” Ortman says.

The housing represented in the data spans non-industrial society from about 12,000 years ago to the recent past, generally ending with industrialization. The collected data then served as a foundation for 10 papers in the PNAS Special Feature, which focus on the archaeology of inequality as evidenced in housing.

Housing similarities

In their introduction to the Special Feature, Ortman, Kohler and Bogaard note that “economic inequality, especially as it relates to inclusive and sustainable social development, represents a primary global challenge of our time and a key research topic for archaeology.

In the PNAS Special Feature published Monday, researchers from around the world describe evidence of inequality found in archaeological data of housing size. (Cover image: Johnny Miller/Unequal Scenes)

“It is also deeply linked to two other significant challenges. The first is climate change. This threatens to widen economic gaps within and between nations, and some evidence from prehistory associates high levels of inequality with lack of resilience to climatic perturbations. The second is stability of governance. Clear and robust evidence from two dozen democracies over the last 25 years that links high economic inequality to political polarization, distrust of institutions and weakening democratic norms. Clearly, if maintenance of democratic systems is important to us, we must care about the degree of wealth inequality in society.”

Archaeological evidence demonstrates a long prehistory of inequality in income and wealth, Ortman and his colleagues note, and allows researchers to study the fundamental drivers of those inequalities. The research in the Special Feature takes advantage of the fact “that residences dating to the same chronological period, and from the same settlements or regions, will be subject to very similar climatic, environmental, technological and cultural constraints and opportunities.”

Several papers in the Special Feature address the relationship between economic growth and inequality, Ortman says. “They’re thinking about not just the typical size of houses in a society, but the rates of change in the sizes of houses from one time step to the next.

“One thing we’ve also done (with the database) is arrange houses from many parts of the world in regional chronological sequences—how the real estate sector of past societies changed over time.”

The papers in the Special Feature focus on topics including the effects of land use and war on housing disparities and the relationship between housing disparities and how long housing sites are occupied. A study that Ortman led and conducted with colleagues from around the world found that comparisons of archaeological and contemporary real estate data show that in preindustrial societies, variation in residential building area is proportional to income inequality and provides a conservative estimator for wealth inequality.

“Our research shows that high wealth inequality could become entrenched where ecological and political conditions permitted,” Bogaard says. “The emergence of high wealth inequality wasn’t an inevitable result of farming. It also wasn’t a simple function of either environmental or institutional conditions. It emerged where land became a scarce resource that could be monopolized. At the same time, our study reveals how some societies avoided the extremes of inequality through their governance practices.”

The researchers argue that “the archaeological record also shows that the most reliable way to promote equitable economic development is through policies and institutions that reduce the covariance of current household productivity with productivity growth.”

GINI Project data, as well as the analysis program developed for them, will be available open access via the Digital Archaeological Record.

With yet another Snow White adaptation currently in theaters, CU Boulder scholar Suzanne Magnanini reflects on the enduring appeal of fairy tales

Once upon a time—this time, in fact, and many of the ones that came before it—there was a story that never grew dull in its telling.

It possibly leaped the porous cultural and national borders of narrative, carried by caravans or ships or ethernet cables and planted in the ready imaginations of successive generations of story lovers—those who tell them and those who hear them.

Maybe it’s the story of a young person who ventures into the unknown, where they encounter magic and beasts of all sizes and a resolution specific to the tale’s time and place. Maybe there really even are fairies involved.

Suzanne Magnanini, a CU Boulder associate professor of Italian and chair of the Department of French and Italian, notes that fairy tales' malleability helps them remain fresh and relevant over centuries of retellings.

And we never seem to tire of hearing about them.

The recent theatrical release of Disney’s live-action Snow White—one of countless retellings of the tale over more than 400 years—highlights the place of honor that fairy tales occupy in cultures around the world and in the hearts of people hearing them for the first time or the thousandth.

One of the reasons they remain fresh through countless years and iterations is their malleability, says Suzanne Magnanini, a �� associate professor of Italian and chair of the Department of French and Italian. “The Italian author Italo Calvino, who also edited a seminal collection of Italian folktales, writes of fairy tales as being like a stone fruit, where you have that hard core center that is always the same—you’ll usually recognize a Sleeping Beauty story, for example—but the fruit can be radically different around that.”

Stories of time and place

As a researcher, Magnanini has published broadly on fairy tales, including her 2008 book Fairy-Tale Science: Monstrous Generation in the Fairy Tales of Straparola and Basile. She began studying fairy tales while working on her PhD, finding in them a fascinating dovetailing between her interests in monstrosity and otherness.

“As a scholar, I take what’s called a social-historical approach,” she explains. “I’m really interested in all those little details that link a tale to a very precise place in time where it was told, and I’ve written about the ways in which fairy tales are used to elaborate on and think about scientific theories of reproduction that hadn’t really been nailed down at the time—questions that were still being circulated about whether humans could interbreed with animals, for example, and would that produce a monstrous child?

“You look at a some variations of Beauty and the Beast, like Giovan Francesco Straparola’s story of a pig king, where it’s a magical version of these questions, and maybe what’s actually happening is that fairy tales are a way to think through the anxieties and interests of the time.”

Fairy Tales at CU Boulder

The ATU Index is one of the search elements that Suzanne Magnanini and her students are including as they develop the database for Fairy Tales at CU Boulder. The project aims, in part, to improve access and searchability of the more than 2,000 fairy tale collections that are part of the Rare Books Collection at Norlin Library.

The project is a partnership between undergraduates and graduate students under the direction of Magnanini and Sean Babbs, instruction coordinator for the University Libraries' Rare and Distinctive Collections, as well as Hope Saska, CU Art Museum acting director and chief curator, who has trained students in visual-thinking strategies. The project is supported by Undergraduate Research Opportunities Program, the ASSETT Innovation Incubator, the President’s Teaching Scholars Program and the University Libraries.

Fairy Tales at CU Boulder will host a showcase of CU's fairy tale collection from 3:30 to 4:45 p.m. April 16 in Norlin Library M350B. Learn more here.

Though fairy tales may be spun in response to what’s happening in a specific time and place, they also often address concerns that aren’t specific to one location or culture but are broadly pondered across humanity. “Andrew Teverson has written that fairy tales are literature’s migrants because they can move across borders, they can move across boundaries and then make themselves at home and assimilate to a certain extent in different cultures,” Magnanini says.

For example, the Brothers Grimm heard a tale called “Sneewittchen” (Snow White) from folklorist Marie Hassenpflug, as well as from other sources, and included it as tale No. 53 in their seminal 1812 Grimm’s Fairy Tales. However, says Magnanini, there was a similar tale called “The Young Slave” in Giambattista Basile’s 1634 work Pentamerone. In fact, Snow White is type 709 in the Aarne–Thompson–Uther Index (ATU Index), which catalogs and describes common motifs and themes in fairy tales and folklore around the world.

Not so happily ever after

The origins of many fairy tales can be traced as far back as ancient Greece, Rome and China, Magnanini says, which speaks to their ability not only to help people of particular times and places explore their anxieties and questions, but to address the feelings that have been central to the human condition almost since our species emerged from caves.

“When I think about fairy tales, I think about number of characteristics that make them really appealing across time and space,” Magnanini says. “If you think about it, the protagonists are almost always young people heading out into the world—much like our students are heading out—leaving home behind, having to make their way in world, facing challenges. That experience can be very transformational, so in a way these stories are all about metamorphosis and change.

“A lot of times that’s when you’re living your life in Technicolor and all the emotions are new. So, even if you’re no longer in that moment of life, fairy tales tap into experiences like the first falling in love, the first adventure from home. And they often end right after the wedding, so you don’t see someone having to do their taxes or being like, ‘Oh, my god, I’ve been in this relationship for 30 years and I’m bored.’ I think part of the reason we don’t get tired of fairy tales is because they capture this fleeting time in life.”

“If you think about it, the (fairy tale) protagonists are almost always young people heading out into the world—much like our students are heading out—leaving home behind, having to make their way in world, facing challenges," says CU Boulder scholar Suzanne Magnanini. (Photo: Disney Studios)

While fairy tales, particularly as they’ve been interpreted and simplified by Disney, are stereotyped as having “and they lived happily ever after” endings, fairy tales pre-Disney more commonly ended with justice served, Magnanini says. For example, the version of “Snow White” in the 1812 Grimm’s Fairy Tales ends with the evil queen being forced to step into a pair of red-hot iron shoes and dance until she dies.

“A lot of people will say, ‘Oh, it’s the happy ending that’s the appeal of fairy tales,’ but it’s important to remember the vast majority of fairy tales end with the deliverance of justice—something really unjust has happened, someone has been discriminated against, there’s some evil in the world, and justice is delivered,” Magnanini explains. “People who study the formal aspects of fairy tales always talk about how the ‘happy ending’ is found in justice.

“Disney Studios has a tendency to remove the ambiguity from these tales and remove most of the violence—simplifying them in a lot of ways. If you read the French version of Beauty and the Beast, Charles Perrault’s version, there were other siblings in there; there was a complex family structure with complex interactions and a lot of really heavy issues—the family must deal with economic disaster.”

In fact, the field of fairy tale scholarship addresses everything from feminist interpretations of the stories to the ways in which children use fairy tales to help navigate psychosexual rites of passage. Generations of authors have told and continue to retell these familiar stories through different lenses of gender, sexuality, geography, racial identity, economic status and many, many others.

“What makes these stories different, and what I think is a big part of the appeal of fairy tales, is the magic or the marvel,” Magnanini says. “For it to be a fairy tale, scholars would say there has to be magic in there—not just the presence of magic, but magic that facilitates the happy ending by allowing the protagonist to overcome whatever obstacles are in the way of what they desire, maybe the marriage, the wealth, the happy ending. There’s something so satisfying about that, because it doesn’t happen in your quotidian day-to-day life. I mean, imagine if you met a talking deer.”

CU prof fighting to keep Latin classes alive through video storytelling

CU prof fighting to keep Latin classes alive through video storytelling Rachel Sauer Tue, 04/01/2025 - 09:51

Cody DeBos

For Reina Callier, learning Latin ‘is like lifting weights for your brain’

When a student in one of Reina Callier’s Latin classes said, “I came for the language, I stayed for the vibes,” she laughed, but the phrase stuck with her.

It captured something essential about Latin classrooms. Beyond conjugations and declensions, they offer students a haven for community, curiosity and a shared passion for the ancient world.

In recent years, though, that community has been shrinking.

Reina Callier, a CU Boulder teaching assistant professor of classics, notes that “Latin survives because people love it. And as long as we keep sharing that love, it’s not going anywhere.”

“Enrollment in Latin classes, especially at the secondary level, has largely been declining,” Callier explains. “During COVID, Latin classes were seen as non-essential, so they lost a lot of students. And they’ve been having a hard time bringing the numbers back up.”

For Callier, a teaching assistant professor of classics and the Latin Program Coordinator at the ��, this trend is more than an academic concern.

She wasn’t alone in her worries. In response to falling enrollment rates, the Colorado Classics Association (CCA) formed a committee dedicated to promoting interest in Latin classes.

The solution? A project that would convey the benefits of learning Latin to students in their own words.

A language in decline

Across the country, Latin programs have struggled to justify their existence in an education system increasingly focused on STEM fields and workforce development. In some districts, administrators have proposed cutting Latin entirely, forcing teachers and students to fight for their programs.

In collaboration with the CCA and local high school educators, Callier helped spearhead You Belong in Latin, a video project designed to remind high school students why Latin is worth learning.

“We finally came up with the idea for a video, because it’s something you can share easily. It’s more entertaining than just looking at a brochure that says, ‘Here’s why Latin is a good thing to take,’” Callier says.

The project quickly took shape as teachers across Colorado filmed interviews with their students, capturing firsthand accounts of what Latin means to them. They also collected footage of classrooms filled with laughter, animated discussions and moments of discovery.

“One of the things we noticed is that once students get into Latin class, they really love it,” Callier says. “You just have to get them in the door.”

The team secured a grant to bring the project to life, which allowed them to hire a former CU Boulder student who majored in film—and took several semesters of Latin with Callier—to professionally edit the videos.

Over the course of a year, the raw footage was transformed into a compelling series of short videos, each emphasizing a unique aspect of the Latin classroom experience.

Now available on YouTube, the You Belong in Latin videos are a vital resource for teachers, students and parents to share.

Latin is for everyone

A central theme of You Belong in Latin is the tight-knit community formed in Latin classrooms. Unlike more popular language programs, Latin classes tend to be small, allowing students to form deeper relationships with their peers and instructors.

“At CU Boulder, if you take Latin, aside from the first semester where there are two sections of Latin I, after that, everybody’s in the same class together,” Callier explains. “You continue to see the same instructors in the department as well. So you get to know them, and you get to know your peers in a way that’s not really very common at the college level.”

The same holds true in high schools, where Latin students often stay in one cohort across multiple years and gain a sense of unity and belonging.

The videos also seek to challenge the misconception that Latin is elitist—a subject reserved for Ivy League prep schools and aspiring academics.

“Latin actually isn’t elitist. Everybody’s starting from the same level when they walk into Latin class. There’s no barrier, and everybody can benefit from it in various ways,” Callier says.

And while Latin’s reputation as a “dead language” often turns students away, Callier argues that its benefits are very much alive. Latin gives students a foundation for English vocabulary, enhances their analytical skills and prepares them for careers in law, medicine and the sciences, she says, adding that it also provides direct access to Latin texts, “which is immensely beneficial to anyone who is enthusiastic about Roman literature or history.

“Latin actually isn’t elitist. Everybody’s starting from the same level when they walk into Latin class. There’s no barrier, and everybody can benefit from it in various ways.”

“Learning Latin is like weightlifting for your brain,” she says with a smile.

Keeping the momentum going

Now that the You Belong in Latin videos have been published, Callier is working to spread the word.

“We have been sharing our Colorado Classics Association YouTube channel with educators from around the country who are looking for different ways to promote Latin,” she says.

Feedback on the project has been encouraging for Latin educators who rarely receive recognition for their efforts.

“What we are doing as Latin educators is something that is really having an impact,” Callier says. “Students are getting a lot out of Latin in various ways, and they’re really appreciating what we bring to the table.”

At its heart, this project isn’t just about keeping Latin alive but also celebrating what makes it special. As Callier and her colleagues know, the language is only the beginning. The real magic comes from the people who learn and teach it.

Callier says, “Latin survives because people love it. And as long as we keep sharing that love, it’s not going anywhere.”

Who has the influence to curb gender bias in STEM?

Who has the influence to curb gender bias in STEM? Rachel Sauer Tue, 03/25/2025 - 07:30

Hint: It’s not women

When Charlotte Moser started graduate school, she was the only woman in a shared office with four male students. One day, a classmate casually remarked that he wished she weren’t there so the office could be all men.

Moser barely had time to process the sting of the exclusion before another male student cut in, calling out the remark as gender bias.

“It felt so great to have someone stand up for me,” Moser recalls. “I felt like someone had my back and I belonged in this space.”

Charlotte Moser, a research associate in CU Boulder’s Department of Psychology and Neuroscience, studies how allyship in male-dominated fields influences workplace culture.

That moment stayed with her—not just because of the personal validation, but because it led her to begin exploring a larger pattern in workplace dynamics.

Now as a research associate in the ��’s Department of Psychology and Neuroscience, Moser studies how allyship in male-dominated fields influences workplace culture. Her findings reveal an unsettling but potentially useful truth: When men openly advocate for gender equality, their voices often carry more weight than women’s do.

The reason? Not necessarily gender, Moser says, but power and influence.

The social influence gap

Moser’s research suggests that in STEM workplaces, where men hold most leadership positions, male allies are perceived as more persuasive, more legitimate and more effective at creating a culture that supports gender equality than their female counterparts.

“We find that men who advocate for gender equality and act as allies tend to be better at signaling to women that they will belong and be respected in male-dominated STEM contexts than when women advocate for gender equality,” Moser says.

Her findings suggest that allyship in male-dominated workplaces isn’t just about intent or even gender. Rather, it’s about who is perceived as having the power to create change.

If a female scientist points out that women are often overlooked for leadership roles or promotions, she may be met with skepticism or dismissed as self-interested. But when a male colleague makes the same argument, research shows that their remark is more likely to be taken seriously and perceived as a norm-setting statement rather than a personal complaint.

“Other work has found that men tend to be perceived more positively than women when advocating for gender equality,” Moser explains. “Women tend to be viewed as whiners, complainers, and only acting in their own self-interest.”

The cost of exclusion

Gender bias in the workplace isn’t a theoretical issue. It has real repercussions.

“A huge consequence is the loss of the contributions from many brilliant women scientists,” Moser says.

Research shows that women are less likely to be retained in male-dominated fields due to factors like persistent bias, exclusion and a lack of support. With fewer women present to offer their perspective, blind spots emerge, and those gaps can have serious, even deadly, implications.

One striking example is the case of crash-test dummies.

“For decades, car-crash dummies were built to represent the average body of a man,” Moser says. “This led women to be much more likely to fall victim to serious injury and death in car crashes.”

Shockingly, car-crash dummies designed to represent women’s bodies weren’t introduced until 2011. Even today, they are tested only in the passenger seat, not the driver’s seat. Recent statistics show that women are 17% more likely to be killed in a car accident and 73% more likely to be seriously injured than male occupants.

This oversight isn’t an accident, but the denouement of decades of scientific decision-making that lacked diverse perspectives.

“More inclusive science is better for everyone—not just those who face bias,” Moser says.

Going beyond performative allyship

If allyship from men is perceived as more effective, what should they do to ensure their support is genuine and impactful?

Moser has a few recommendations.

“I would say that men who don’t know where to start could start within their own spheres. Pay attention to what’s going on, how people are treated, and listen to the women around you,” she says.

But listening is only the first step.

Moser emphasizes that standing up against gender bias isn’t just about making statements on social media or in private. Meaningful allyship requires action.

Calling out dismissive remarks in a team meeting or challenging biased hiring decisions can have an immediate effect. Those in leadership positions can stretch their influence further by advocating for equitable organizational policies and ensuring women have access to mentorship and career-advancement opportunities.

“One hurdle for men regarding allyship for gender equality is that they feel that it is ‘not their place,’” Moser says. “I hope that my work can show that allyship from men is not only wanted but very beneficial to women.”

However, Moser warns that inauthentic allyship—publicly claiming to support gender equality without backing it up—can make meaningful change even harder to achieve.

“The future of allyship isn’t just about who speaks. It’s about who gets listened to.”

“I have other work showing that it is worse to claim allyship but then do nothing to promote equality than if one had said nothing about inequality and allyship in the first place,” she says.

Who deserves to be heard?

Moser’s research makes clear the fact that eliminating gender bias in the workplace isn’t a matter of men versus women. Rather, it’s about recognizing and altering the systems that create credibility and influence.

“I think allyship can change the narrative of the widespread belief that most men don’t care about women and change the narrative that it’s women’s responsibility to make these workplaces work for them,” she says.

But the goal isn’t just getting men to use their influence—it’s about redistributing power so that women’s voices carry the same weight without needing male validation.

“The future of allyship isn’t just about who speaks,” Moser explains. “It’s about who gets listened to.”

CU Boulder religious studies professor says Twelver Shi’ism is open to discourse

CU Boulder religious studies professor says Twelver Shi’ism is open to discourse Rachel Sauer Mon, 03/17/2025 - 09:09

Bradley Worrell

Associate Professor Aun Hasan Ali’s book about Islam’s School of Hillah explores the dynamics and formation of Twelver Shi’ism, arguing that the faith was open to diverse intellectual traditions

Twelver Shi’ism, the largest branch of Shi’ite Islam, tends to be viewed as fundamentally authoritarian, particularly as seen through the lens of the ideology of the Iranian government.

Aun Hasan Ali, associate professor in the �� Department of Religious Studies whose area of focus is on Islamic intellectual history, particularly pre-modern Twelver Shi’i traditions, says he believes that modern perceptions of the faith have been colored by the 1979 Iranian Revolution.

“It was an unprecedented moment in a lot of ways, because for the first time in the history of Shi’ism, you had a theory of government where the jurist was the head of the state,” he says. “Traditionally, there was always a kind of separation between those two spheres.”

Aun Hasan Ali, CU Boulder associate professor of religious studies, argues that modern perceptions of Twelver Shi'ism have been colored by the 1979 Iranian Revolution.

As a result, Ali says the idea took root among some in the West and also in the Muslim Sunni tradition that Shi’i clerics were free to make whatever political or religious decisions they pleased, because they were not bound by the history of tradition. However, that’s not an accurate portrayal of how jurists and other followers come to decisions in Twelver Shi’i religious tradition, he adds.

Instead, Ali makes the case that Twelver Shi’ism is better understood as a “discursive tradition,” which, as defined by noted cultural anthropologist Talal Asad, involves researching foundational Islamic texts, such as the Quran and the writings of exemplary historical Shi’i religious figures, for context. Ali says his own definition of discursive tradition is tied less to foundational texts and more to how noted Shi’i religious figures interpreted those texts, as that is how most followers of the faith first engage on religious topics.

“In the same way that someone addressing ethics in contemporary philosophy needs to address (Immanuel) Kant, for instance, I view that as a parameter of the conversation,” he explains. “Similarly, when it comes to Islamic tradition, there are important figures that one needs to address. So, in the simplest terms, a discursive tradition should be thought of as a conversation across time and space among experts.”

In contrast to the idea that scholars make decisions based solely upon their authority, Ali contends that thinking of the Twelver Shi’i faith as a discursive tradition means the faith continually remains open to discussion, debate, mediation and modification.

Ali’s ideas on discursive tradition were shaped in part by his PhD dissertation on the School of Hillah, a center of religious learning that played a major role in preserving and promoting Twelver Shi’i Islamic religious traditions, while also being open to integrating diverse intellectual traditions, during its formative years, from the 12th to 14th centuries. Ali’s revised dissertation was published in 2023 by I.B. Taurus as the book, The School of Hillah and the Formation of Twelver Shi’i Islamic Tradition, which is being translated into Arabic for wider distribution.

Recently, Ali spoke with Colorado Arts and Sciences Magazine about the importance of the School of Hillah in the formation of Twelver Shi’ism and its profound effect on the Shi’i faith today. His answers have been lightly edited and condensed for space considerations.

Question: Why does the School of Hillah take root in what is now southern Iraq?

Ali: Hillah becomes a center of scholarship for two reasons. One is that you have a (regional) Shi’i dynasty come to power that patronizes these scholars. The second reason is that you have the Mongol invasion in the 13th century, which pushes a lot of people looking to escape that devastation southward.

So, you end up with a concentration of scholars who are sought-after in the region. People travel to Hillah from the Levant, from Bahrain and from Iran. They travel there because they were seeking expert education, and the major figures of Hillah were the undisputed experts. (Students) came there to receive that kind of education in the same way that today somebody might come to CU seeking a world-class program in astrophysics. The same thing was happening in Hillah; they came there to learn from these masters.

With the Mongol invasion, sure, there’s devastation, but there are also opportunities. There are trade routes that enrich particular families in the area, and, as we all know, education requires money, so the influx of wealth also becomes a reason why they’re able to offer patronage to those scholars.

In The School of Hillah and the Formation of Twelver Shi’i Islamic Tradition, which is being translated into Arabic for wider distribution, author Aun Hasan Ali explores the School of Hillah, a center of religious learning that played a major role in preserving and promoting Twelver Shi’i Islamic religious traditions.

Question: Is the School of Hillah equivalent to what we would think of today as a university or maybe a seminary?

Ali: Certainly, it’s different in the sense that it’s not primarily organized in brick-and-mortar institutions. It’s more unstructured. Classes took place in the home of an individual, a prominent scholar.

It’s similar in the sense of curriculum. What I mean is that certain texts come to be understood as definitive of a tradition. And that’s part of the reason why Hillah is so important. A lot of the texts that we think of today as being definitive of Shi’i tradition were written in Hillah and continue to be studied today, so we can think of it in terms of there is, not uniformity, but an expectation that anybody who masters this tradition would read these texts. In that sense, it’s similar.

It’s also similar in the sense of structures of authority. Just as someone wishing to put forth a view in, let’s say, American jurisprudence, has to engage particular jurists; similarly, somebody wishing to put forward a view in Shi’i theology has to engage with the views of particular jurists. So, structures of authority can be similar in that way. The idea of a curriculum can be similar in that way, but it’s not organized as a single space in primarily brick-and-mortar institutions.

That was actually one of the points in the book. The organizing principle of the School of Hillah is these large families in which particular types of expertise is concentrated. So, one family may have an expertise in genealogy; another family may have an expertise in philosophy; while another family may have an expertise in law. These large families (in the community) structure the School of Hillah. And, of course, people intermarry between these families, so it becomes a network of intellectuals.

Question: For the students who completed their studies at Hillah, did they generally go on to become clerics and religious scholars?

Ali: If we look at the contemporary Twelver Shi’i tradition, it runs the full gamut. Before you have modern schools, people learn basic numeracy and literacy in religious institutions, which is the same as it was in the West.

Some of those people, after getting basic literacy and numeracy, go on to become merchants or preachers, for example. A smaller group will become teachers within the institution, and then a (small percentage) of those will become the next generation of masters of the tradition. Most people don’t reach that level, because it takes a long time—we’re talking maybe 20 years or more—to be considered competent within that tradition. It’s a very grueling process, and most people leave before they finish the entire process.

Question: Can you talk about how your idea of discursive tradition contrasts with the idea of jurists having the authority to make whatever decisions they want?

Ali: That’s exactly the idea I was pushing back against in the book—this kind of free-for-all idea about authority. That’s not to say authority isn’t important, or that jurists don’t exercise that kind of authority. But again, they do it within the horizons of possibility that are shaped by discursive tradition, as a conversation across space and time.

And yes, there’s a kind of push and pull where a really important figure can push a conversation forward, can expand at the horizons of possibility, but it’s not an arbitrary process. It’s a process that’s linked to the past at the same time that it looks ahead.

Question: Were there any major developments or contributions that came out of the School of Hillah that made a profound impact on Islam today?

Ali: Philosophy becoming integrated into theology is something that we can look to Hillah for, within the Shi’i world. That development takes place earlier within the Sunni world, but in the Shi’i world, Avicenna’s philosophy, or Avicenna’s metaphysics, comes to be integrated into Shi’i theology. In that time period, the integration of mysticism into Shi’ism is also something that happens in Hillah.

"There’s a kind of push and pull where a really important figure can push a conversation forward, can expand at the horizons of possibility, but it’s not an arbitrary process. It’s a process that’s linked to the past at the same time that it looks ahead."

When we think of (Islamic) law, that’s really one of the most important contributions that happens at Hillah, and you see the integration of advanced mathematics and advanced science into law. For example, in Islamic law, figuring out the direction of prayer from a distance, given the curvature of the earth is also a complicated thing, which leads to advanced discussions of science and mathematics integrated into the chapter on ritual prayer, for instance. Those would be a few examples.

At Hillah, you also have the production of these kinds of biographical dictionaries. So, when Muslims evaluate a piece of information, part of the way they evaluate it is by looking at who communicated that information. You can imagine that it would be very useful to have a kind of a biographical dictionary, where you could look up a particular individual and see what they were like. Were they known to be somebody who had scholarly expertise? Were they known to be somebody who was an upright person? Or were they known to be unscrupulous in the way that they narrated information? These kinds of biographical dictionaries, which facilitate legal discussions and conversations, were produced at Hillah.

Question: Despite the School of Hillah’s contributions to Islamic thought, you say there is not much scholarship about it. Why do you think that is?

Ali: I believe a lot of it has to do with the history of Islamic studies in the West—and that only in recent years has Shi’ism gotten the attention it deserved. Previously, scholars who studied Islam largely dealt with Sunni sources. And so, even when they talked about Shi’ism, they were talking about it through the lens of Sunni authors and Sunni sources.

This is despite the fact that Shi’ites—while making up somewhere between 15 and 20 percent of the (Muslim) population—their contributions, intellectually, to Islamic tradition has been disproportionate.

Things started to change in the 1980s and 1990s, but even among scholars focused on Shi’ism, they have tended to focus on its origins, or trying to explain how the Iranian Revolution happened, so in both of those ways Hillah was ignored.

Question: Do you have any particular hopes for your book?

Ali: In general, the book has been received well. I think that people (in Islamic studies) recognize this was a crucial period in Shi’i religious history that hadn’t really been sketched out the way I did in the book.

In terms of contributing to a broader discussion, my hope is the book brings together theoretical conversations in religious studies with meticulous historical scholarship. In Islamic studies, it’s sometimes separated by people who do theoretically rigorous projects and people who do meticulous historical scholarship. I tried to do both, and I hope that the book contributes to bridging the gap between these two different approaches within Islamic studies.

An ultrafast microscope makes movies one femtosecond at a time Rachel Sauer Tue, 03/11/2025 - 10:18

New CU Boulder research harnesses the power of an ultrafast microscope to study molecular movement in space and time

The interactions in photovoltaic materials that convert light into electricity happens in femtoseconds. How fast is that? One femtosecond is a quadrillionth of a second. To put that in perspective, the difference between a second and a femtosecond is comparable to the difference between the second right now and 32 million years ago.

Subatomic particles like electrons move within atoms, and atoms move within molecules, in femtoseconds. This speed has long presented challenges for researchers working to make more efficient, cost-effective and sustainable photovoltaic materials, including solar cells. Imaging materials on the nanoscale with high enough spatial resolution to uncover the fundamental physical processes poses an additional challenge.

Understanding how, where and when electrons move, and how their movement depends on the molecular structure of these materials, is key to honing them or developing better ones.

Ultrafast nano-imaging of structure and dynamics in a perovskite quantum material also used for photovoltaic applications. Different femtosecond laser pulses are used to excite and measure the material. They are focused to the nanoscale with an ultrasharp metallic tip. The photo-excited electrons and coupled changes of the lattice structure (so called polarons, red ellipses) are diagnosed spectroscopically with simultaneous ultrahigh spatial and temporal resolution. (Illustration: Branden Esses)

Building on more than five years of research developing a unique ultrafast microscope that can make real-time “movies” of electron and molecular motion in materials, a team of �� scientists published in Science Advances the results of significant innovations in ultrafast nanoimaging, visualizing matter at its elementary atomic and molecular level.

The research team, led by Markus Raschke, professor of physics and JILA fellow, applied the ultrafast nanoimaging techniques they developed to novel perovskite materials. Perovskites are a family of organic-inorganic hybrid materials that are efficient at converting light to electricity, generally stable and relatively easy to make.

Working with a thin perovskite layer, the researchers directed ultrashort laser pulses onto tiny metallic tips positioned above the perovskite layer. The tip functions like an antenna for the laser light and focuses it to a spot much smaller than what is possible in conventional microscopes. The tip is then scanned across the perovskite layer, creating an image pixel by pixel. Each image provides one frame of a movie as the different laser pulses are varied in time.

The movie also has “color,” albeit in the infrared and invisible to the human eye but where the molecules and electrons respond. Through different wavelengths of light, the researchers can follow both the electron and molecular motion and their coupling, which is what controls the photovoltaic efficiency in perovskites.

This milestone not only helps them better understand the missing links between the perovskite’s crystal structure and composition and its performance as a photovoltaic material but also led to the surprising discovery that more disorder seems to facilitate better photovoltaic performance.

“We like to say that we’re making ultrafast movies,” Raschke says, adding that there have long been many unknowns about the elementary processes after sunlight gets absorbed in photovoltaic materials and how the excited electrons move in them without being dispersed, but “for the first time, we can actually sort this out because we can record spatial, temporal and spectral dimensions simultaneously in this microscope.”

Molecules as spectators of how the electrons move

In recent years, much research has focused on perovskites, particularly in the quest to create more efficient and sustainable solar cells. These materials absorb certain colors of the visible spectrum of sunlight effectively and can be layered with other materials, such as silicon, that catch additional wavelengths of light the perovskite does not absorb.

"This is a way to examine the material properties on a very elementary level, so that in the future we’ll be able to design materials with certain properties in a more directed way."

“(Perovskites) are easy to fabricate and have a very high solar cell efficiency, and can be applied as a very thin film,” explains Roland Wilcken, first author on the new paper and a post-doctoral researcher in Raschke’s research group. “But the problem with this material is it has relatively low photostability.”

Improving the material’s performance is no easy feat. There’s a large possible combination of chemical compositions and preparation conditions of perovskite solar cells, which affect their structure, performance and stability in ways that are difficult to predict. This is a challenge also faced by many other complex materials used for semiconductors, quantum materials, displays or in biomedical applications.

This is where the ultrafast microscope helps the researchers gain the spatial and temporal information needed to optimize the material—and in turn—find a good compromise between stability and performance.

Building the ultrafast microscope was a challenge, explained Branden Esses, a physics graduate student and research contributor. The team used nanotips, coated in a platinum alloy or gold, which are brought within nanometers of the perovskite layer, then hit with a sequence of laser pulses.

The first pulse excites the electrons in the visible, and subsequent pulses in the infrared watch how the electrons and molecules interact and move in time, Esses says, adding that “if you shine a light on this very tiny tip, the light that comes back is very weak since it only interacts with very few electrons or molecules; it’s so weak that you need special techniques to detect it.”

So, they developed a special method, modulating the light beams and using optical-amplification techniques to reduce noise and background to isolate the desired information.

Both how “the light is focused at the nanometer scale with the tips and how it is emitted and detected was essential to get enough contrast and signal to make these ultrafast movies of the material,” Wilcken explains.

And thanks to the ultrafast microscope technology, researchers are able to capture ultra-high-resolution images of femtosecond movement, measuring atomic motion in the molecules with very high precision. A particular feature of this development is the ability to resolve the dynamics of the molecular vibrations as a spectator of how the material responds to the photoexcited electrons.

Building better and functional materials from the bottom up

“This is a way to examine the material properties on a very elementary level, so that in the future we’ll be able to design materials with certain properties in a more directed way,” explains Sean Shaheen, a professor of electrical, computer and energy engineering who provided the material sample and collaborated on the research.

“We’re able to say, ‘We know we prefer this kind of structure, which results in, for example, longer lived electronic excitations as linked to photovoltaic performance,’ and then we’re able to inform our material synthesis partners to help make them,” Esses adds.

One of the surprising results of the work is that “in contrast to conventional semiconductors it seems that more structural disorder gives rise to more stable photogenerated electrons in hybrid perovskites,” Raschke explains. With the ultrafast microscope it became possible for the first time “to directly image the role of molecular order, disorder and local crystallinity on the optical and electronic properties of materials in general.”

This discovery is expected to have a profound impact on material science for advancing the performance of novel semiconductor and quantum materials for computing, energy and medical applications.

The instrument development was supported by the National Science Foundation, through STROBE, an NSF Science and Technology Center for which Raschke serves as co-principal investigator.

‘Kenough’: Is 'Barbie' more revolutionary for men than women?

‘Kenough’: Is 'Barbie' more revolutionary for men than women? Rachel Sauer Fri, 03/07/2025 - 14:08

Clay Bonnyman Evans

CU Boulder PhD student’s paper argues that the hit film exemplifies ‘masculinity without patriarchy’ in media

M.G. Lord, author of Forever Barbie: The Unauthorized Biography of a Real Doll and co-host of the podcast LA Made: The Barbie Tapes, describes Greta Gerwig’s Oscar Award-winning, box-office behemoth Barbie as “incredibly feminist” and widely perceived as “anti-male.”

Meanwhile, conservative critics rail that the movie is “anti-man” and full of “beta males” in need of a testosterone booster. Conservative British commentator Piers Morgan called it “an assault on not just Ken, but on all men.”

CU Boulder PhD student Julie Estlick argues that Greta Gerwig's award-winning film Barbie is "a really good film for Ken."

But �� women and gender studies doctoral student Julie Estlick sees things differently. In her recent paper, “Ken’s Best Friend: Masculinities in Barbie,” published in Feminist Theory, she argues that the movie is “a really good film for Ken.”

On first viewing, Estlick noticed a woman nearby having a “very visceral, emotional response” to the now iconic monolog by actor America Ferrera, which begins, “It is literally impossible to be a woman.”

She wasn’t particularly moved by the speech, and walking out of the theater, she realized she didn’t see the movie as a clear-cut icon of feminism.

“I really questioned whether the film was actually about Barbie, and by extension, women, at least in the way people were claiming,” she says.

Once Barbie was available for streaming, Estlick took a closer look and arrived at a heterodox conclusion:

“Barbie is not anti-man; it is pro-man and is not necessarily a revolutionary film for women, at least not as much as it is for men,” she writes in the paper’s abstract. “This is because Barbie espouses non-hegemonic masculinity through cultural critiques that are rare to see in popular media.”

Hegemonic vs. toxic masculinity

For Estlick, “hegemonic masculinity” is a kind of stand-in for the “toxic masculinity” so often featured in media: superheroes, gangsters, vigilantes, killing machines who are also “lady killers.” Always strong, rarely emotional, such men are absurdly impermeable to harm, and sport chiseled features and perfectly sculpted abs, she says. Yet many are also “man children” whose “ultimate prize” is to have sex with a woman.

“That kind of media comes at the expense of women, works against women, and often oppresses women by sexualizing and objectifying them,” Estlick says.

In the film Barbie, the patriarchy ultimately doesn't serve the Kens any more than it does the Barbies, argues CU Boulder PhD student Julie Estlick. (Photo: Warner Bros. Pictures)

Non-hegemonic masculinity is strong without being oppressive, and supportive and protective of women without regard to any quid pro quo. It allows for men to openly express emotions and vulnerability and to seek help for their mental-health struggles and emotional needs without shame, while retaining their strength, vitality and masculinity.

“It does the opposite of hegemonic masculinity,” Estlick says. “It works alongside women and doesn’t harm them in any way.”

The Kens are first represented in the movie as clueless accessories to the ruling Barbies of Barbie Land. But after Beach Ken (Ryan Gosling) and Stereotypical Barbie (Margot Robbie) find a portal to our world, Beach Ken returns and establishes a patriarchal society in which women become mindless accessories to hyper-competitive men in the thrall of hegemonic masculinity.

But ultimately, the patriarchy doesn’t serve the Kens any more than the Barbies.

“As people always say, men’s worst enemy under patriarchy isn’t women. It’s other men and their expectations, who are constantly stuffing men into boxes,” Estlick says.

Which isn’t to say that women don’t also enforce strictures of hegemonic masculinity.

“When little boys are taught to suppress emotions, little girls are watching. They are watching their fathers, and fathers onscreen, acting in certain ways,” Estlick says. “Girls internalize toxic ideologies the same ways boys do.”

Allan the exception

In Barbie, there is just one male who stands apart from Kendom: Allan, played by Michael Cera.

“Allan is positioned as queer in the film in that he is othered but not less masculine in the traditional understanding of the word,” Estlick writes. He “deviates from the conventional canon of masculinity” and “uses his masculinity for feminism and to liberate women while also protesting patriarchy.”

Allan doesn’t fit into Kendom, with or without patriarchy. As the narrator (voiced by Helen Mirren) notes, “There are no multiples of Allan; he’s just Allan.”

The character is based on a discontinued Mattel doll released in 1964, intended to be a friend to Ken. Fearing the friendship might be perceived as gay, the company swiftly removed Allan from store shelves, later replacing him with a “family pack” featuring Barbie’s best friend Midge as his wife, and a backstory that the couple had twins.

In the film, non-toxic Allan is immune to patriarchal brainwashing and sides with the Barbies in re-taking Barbie Land.

“(T)he film can be understood as a vital framework for masculinity that allows for vulnerability, emotion and heterosexual intimacy among men,” says researcher Julie Estlick. (Photo: Warner Bros. Pictures)

“Right off the bat we see (Allan) as queered from the rest of the Kens and Barbies,” Estlick says.

But Beach Ken, too, eventually senses that he’s not happy in the patriarchal society has created. In one of the movie’s final scenes, a tearfully confused Beach Ken converses with Stereotypical Barbie from a literal ledge:

“You have to figure out who you are without me,” Barbie tells him kindly. “You’re not your girlfriend. You’re not your house, you’re not your mink … You’re not even beach. Maybe all the things that you thought made you aren’t … really you. Maybe it’s Barbie and … it’s Ken.”

In other words, Barbie is rooting for Ken to claim his individuality.

“Beach Ken’s house, clothes, job and girlfriend all represent boxes that society expects men to tick, but this scene illustrates that it is okay to deviate from normative behaviors of masculinity and that manhood is not solely defined through heteronormative bonds and behaviors,” Estlick writes. And “it is acceptable for men to admit to a woman that they need help.”

Barbie is pure, candy-colored fantasy. But in our world, Estlick believes it points the way toward further non-toxic media representations of masculinity and ultimately contribute to better mental health for men trapped in a “man box” — as well as women who have borne the burden of men’s self- and societally imposed strictures on their own humanity.

“(T)he film can be understood as a vital framework for masculinity that allows for vulnerability, emotion and heterosexual intimacy among men,” she concludes. It “(opens) the door to the creation of more media that subverts societal expectations of toxic masculinity.”

CU Boulder researcher Eva Pietri studies how stories can help address gender bias and create inclusivity

Eva Pietri wasn’t planning on being part of a documentary.

When the �� associate professor of psychology and neuroscience was contacted by the creators of Picture a Scientist, a film that takes an unflinching look at sexism and discrimination in STEM (science, technology, engineering and math), she was thrilled to discuss her research. Pietri, who has an extensive background studying gender bias in STEM, knows interventions often fail because facts alone rarely change minds.

But when paired with human narratives, they become undeniable.

“I think one danger with anything that talks about bias is that it might dishearten people. But storytelling, when done right, can motivate people to do something about it," says Eva Pietri, a CU Boulder associate professor of psychology and neuroscience.

“They’re doing exactly what I would have recommended,” Pietri recalls thinking as she watched the film engage audiences with compelling stories supported by data.

Now, Pietri’s latest research explores how storytelling can be a powerful tool for shifting perceptions about gender bias and creating more inclusive environments. It supports what filmmakers have long believed—that stories can change culture.

Why facts alone aren’t enough

Traditional diversity training in STEM often follows a familiar formula: workshops, slideshows and statistical breakdowns of workplace disparities. Though well intentioned, such initiatives often fail to change minds.

Facts alone, it turns out, aren’t always enough.

“It’s easy when you hear one story, especially if you aren’t motivated to believe it, to think, ‘Well that was just you,’” Pietri explains. “But if we have some data to back that story up, the combination can be more persuasive.”

Her studies in social psychology reveal that the most effective interventions engage both the rational and emotional centers of the brain. This phenomenon, known as narrative persuasion, happens when people become absorbed in a story.

In short, emotional investment makes us more likely to find a new perspective and reconsider past assumptions.

“Having communications that use both stories and the data can be really powerful. And I think documentaries are a unique platform to do that,” Pietri says.

That’s precisely what makes Picture a Scientist effective. The film follows three women in STEM careers who recount their experiences with bias, harassment and institutional roadblocks. Their stories create an emotional connection, making it difficult for viewers to dismiss sexism as an abstract problem.

A case study in narrative persuasion

When Picture a Scientist arrived in 2020, its timing created an unusual moment. The COVID-19 pandemic had forced companies and universities to rethink their approach to workplace training, including diversity programs.

Traditional workshops, which already struggled to engage audiences, were relegated to Zoom. But the documentary offered a more compelling alternative.

Pietri and her colleagues saw an opportunity.

The filmmakers had already consulted with her during production, but after the film’s release, they proposed a new collaboration—testing whether it was truly changing attitudes and behaviors.

“Often diversity interventions are not evaluated,” Pietri says. “You could do a diversity training, and it could have worse effects or just no effect, and you’ve wasted all these resources.”

So Pietri and her team designed a study to measure the documentary’s impact. They found that Picture a Scientist was prompting real-world action, not just raising awareness.

“One of the most consistent findings we saw was with information seeking. The more people felt transported, the more they engaged emotionally with the film, the more likely they were to want to learn more about gender bias,” she explains.

Likewise, the study showed that this information-seeking behavior often persists after the initial screening.

“One really positive finding is that people who watch the film are motivated to continue looking up these issues and figuring out how they can make their workplace more equitable. They’re putting themselves in a position to keep gaining knowledge,” Pietri says.

Indeed, participants surveyed a month or more after watching the film reported stronger effects than those who answered immediately, suggesting that the film’s impact is long-lasting.

Pietri believes its entertainment value is partly responsible.

“I mean, this documentary is created by filmmakers, right? They’re not just academics. They know how to create something that’s really entertaining,” she says. “That’s why it was streaming on Netflix, because people, even outside their institutions, are just excited to watch it.”

Of course, stories don’t just educate. They also inspire.

Traditional bias training often focuses on the barriers marginalized groups face, which, while important, can leave viewers feeling hopeless rather than empowered. But when Picture a Scientist viewers see women overcoming challenges, it creates something valuable: role models.

“The film doesn’t just show bias,” Pietri says; “it also highlights these incredible women in STEM. And for students, especially female students of color, that representation is powerful.”

Limiting objections and creating change

Research shows that when people feel forced into a training session, they often react defensively, resisting the very ideas the program promotes. But storytelling doesn’t elicit the same pushback. Instead of feeling lectured, viewers become immersed in a story where they can process difficult topics with less resistance.

"One really positive finding is that people who watch the film are motivated to continue looking up these issues and figuring out how they can make their workplace more equitable. They’re putting themselves in a position to keep gaining knowledge"

That’s one reason Pietri believes storytelling and creative interventions will play an important role in the future of diversity training in STEM.

“This story-based approach addresses some of the limitations of traditional diversity workshops. Aside from people maybe being actually excited to see it and participate, it’s also very scalable,” Pietri says.

“We can show it without having to train facilitators or fly people out to host a panel or host multiple live sessions over Zoom. It’s really easy to scale and it’s not super expensive,” she adds.

Training alone won’t eliminate STEM’s gender-bias problem. However, Pietri’s work suggests that the right intervention can make a difference.

“I think one danger with anything that talks about bias is that it might dishearten people,” she says. “But storytelling, when done right, can motivate people to do something about it.”

Perhaps the most important lesson is that when building a more inclusive STEM community, in a field that thrives on innovation, a good story can be just as efficacious as the right experiment.

“If we can use the small windows for change opened by stories like this to make progress in reducing inequality and suffering, that would be a real win for current and future generations,” Pietri says.
