Remembering victims of the Holocaust by speaking their names Rachel Sauer Wed, 04/08/2026 - 15:01

Holocaust Remembrance Day, or Yom HaShoah, will be observed on �鶹��Ѱ��Boulder campus Tuesday with a public reading of the names of Jews killed in the Holocaust

The �鶹��Ѱ�� community will observe Yom HaShoah, or Holocaust Remembrance Day, on campus Tuesday with a public reading of the names of European Jews murdered by the Germans and their allies during the Holocaust.

Chancellor Justin Schwartz will begin the reading of named at 10 a.m. at the Dalton Trumbo Fountain Court in front of the University Memorial Center, and the reading of names will continue until 3 p.m.

Event organizers encourage members of the campus and broader communities to participate in the readings. Prospective participants may sign up here.

The U.S. Congress established the Days of Remembrance in 1980 as the nation’s annual commemoration of the Holocaust. The United States Holocaust Memorial Museum in Washington, D.C., which opened in 1993, leads the nation in observing Days of Remembrance and encourages observances throughout the United States.

Holocaust Remembrance Day

What: Public readings on Yom HaShoah

When: Tuesday, April 14, from 10 a.m. to 3 p.m.

Where: Dalton Trumbo Fountain Court in front of the University Memorial Center.

The main event takes place at the U.S. Capitol, often attended by the U.S. President. In Israel, the Holocaust Martyrs’ and Heroes’ Remembrance Day (Yom HaShoah in Hebrew) is a national day of commemoration on which the 6 million Jews murdered in the Holocaust are memorialized.

It begins at sunset on the 27th of the month of Nisan, the first month of the Jewish calendar, and ends the following evening, according to the traditional Jewish custom of marking a day. Established in 1953 by a law from the Knesset, Israel’s parliament, it falls close the anniversary of the 1943 Warsaw Ghetto Uprising.

The central ceremonies, in the evening and the following morning, are held at Yad Vashem, Israel’s official memorial to victims of the Holocaust.

During Yom HaShoah ceremonies in the United States, Israel and elsewhere, people read the names of Jews murdered by the Germans and their allies during the Shoah.

“The events of the Holocaust are given meaning only by remembering the individuals who died during that time,” Rabbi Sharon Sobel writes. “We gather as a community, we remember the names of those who died, and we affirm their lives by how we choose to lead our lives. So, names, indeed, are very powerful. ... We honor those who came before us and those who perished during the Holocaust by giving our names—and their names meaning through our actions and aspirations and the way we fulfill them.”

The �鶹��Ѱ��Boulder event is presented by the Program in Jewish Studies, the Department of History and Center for Humanities and the Arts.

Though the reading of names occurs each year, “they have not lost any of their meaning and significance,” says Thomas Pegelow Kaplan, the Singer Endowed Chair in Jewish History. “On the contrary.”

In new book God Bless the Pill, �鶹��Ѱ��Boulder scholar Samira Mehta delves into the often-forgotten history of how liberal religion helped make birth control broadly available in America

A little more than 100 years ago, the Episcopalian stance on birth control was this: “We utter an emphatic warning against the use of unnatural means for the avoidance of contraception, together with the grave dangers—physical, moral and religious—thereby incurred, and against the evils with which the extension of such use threatens the race.”

Even acknowledging “abnormal cases” in which birth control might be necessary, Episcopalians were just one of many Protestant denominations that, in the early 20th century, “reacted to contraception on a continuum from skeptical to disapproving,” writes Samira Mehta, a �鶹��Ѱ�� associate professor of women and gender studies and director of the Program in Jewish Studies.

This aligns with commonly held ideas about how contraception—specifically the pill, which received FDA approval in May 1960—became broadly available in the United States: that first- and second-wave feminists pushed for accessibility, policy change and social revolution while religious leaders erected roadblocks and preached against it.

�鶹��Ѱ��Boulder scholar Samira Mehta's new book, God Bless the Pill, explores how liberal religion helped make birth control broadly available in America.

Except this doesn’t actually tell the whole story.

In her new book God Bless the Pill, scheduled for publication April 14, Mehta details the often-forgotten history of mid-20th-century Protestant, Jewish and Catholic leaders and believers who embraced birth control as part of God’s plan. In fact, many denominations that were “skeptical to disapproving” in the early 20th century came around to supporting and advocating for birth control and family planning.

“In a society that overtly thought of sex as something inside of marriage and that was inappropriate outside of marriage, the way that birth control becomes something that is covered by insurance and a part of respectable medicine lay in reshaping it from a tool for sexual liberation and turning it into a tool for creating properly structured American families,” Mehta says.

“This didn’t happen because (as a society) we care about women but because children have a better start if their mother doesn’t die in childbirth, if their family doesn’t have more children than the parents can provide for. The goal was to create healthier families—to use birth control to create healthier families—not just a healthy mother. And there’s concern that if you have more children than you can afford, you become dependent on the state. This is the United States, where we don’t want you to need a school lunch program, so you can’t have more kids than you can afford to give lunch to.”

The role of liberal religion

The idea to research what became God Bless the Pill, Mehta says, germinated from a desire not to lessen the significant influence that first- and second-wave feminism had on making birth control broadly available to women, but to understand what, if any, influence liberal religion had on the accessibility of birth control.

Book release and Q&A

What: A reading from God Bless the Pill by author Samira Mehta, followed by a Q&A facilitated by Phoebe Young, chair of the �鶹��Ѱ��Boulder Department of History

Where: Waldschänke Ciders + Coffee, 4100 Jason St. in Denver

When: 6-8 p.m. Monday, April 13

Who: All are invited to this free event.

Mehta was inspired by social historian Elaine Tyler May’s America and the Pill: A History of Promise, Peril, and Liberation, in which May assesses how access to the pill did and didn’t fulfill utopian dreams of liberating women, eradicating global poverty and supporting stable and happy marriages.

Mehta understood that the history of contraception is not simply a feminist history and found herself wondering what “that story would look like if one fully included religion in the narrative? I hoped and assumed that, as in May’s title, the promise and liberation might outweigh the peril. I also saw in May’s narration the assumption that religion was always conservative and opposed to birth control,” she writes in God Bless the Pill.

But what about liberal religious congregations? Where were they in the aftermath of oral contraception becoming broadly available in 1960?

Mehta took that question to the Schlesinger Library at Harvard University, where she found documentation of her childhood minister, the Rev. Al Ciarcia of the Unitarian Universalist Church of Greater Bridgeport in Connecticut, publicly supporting birth control during the Griswold v. Connecticut debate—a landmark 1965 U.S. Supreme Court case in which the court found that a Connecticut statute forbidding contraceptive use violated the right of marital privacy.

This decision came 25 years after the American Birth Control League, formed by Margaret Sanger in 1921 and renamed the Planned Parenthood Federation of America in 1942, assembled a national clergymen’s committee.

“These clergy talk about the importance of sex in a marriage and how a marriage that is sexually dynamic is less likely to result in divorce,” Mehta says. “The rhetoric around sex and marriage starts changing, and clergy members start talking about the sacred nature of a marriage bond and how sex is part of that bond through which two become one—regardless of literally becoming one in the form of a new person.

"The way that birth control becomes something that is covered by insurance and a part of respectable medicine lay in reshaping it from a tool for sexual liberation and turning it into a tool for creating properly structured American families," says Samira Mehta.

“They also advocate for marriages that are economically stable, and more kids can strain the economics of the household.”

Making the moral choice

Though Mehta begins the narrative in God Bless the Pill during World War II, the story of religion and contraception really gathers steam after the war’s end and the Cold War’s beginning. During this time, the value and sanctity of the American family was touted as one of the best weapons against the communist menace.

“There’s talk about Soviet women who have to go out and work in factories and put their kids in daycare,” Mehta says. “But a family that can control how many kids they have—where the mother can stay home and the father’s income is enough to support the family—can control their discretionary income. They can get a KitchenAid stand mixer, they can replace the dishwasher when a new and better model comes out. Limiting the birth rate becomes a way of increasing capitalist consumption.”

Messages highlighting capitalism as a way to defeat communism often occurred in the same breath as messages of moral behavior: “It’s the idea that if you can’t control something, it’s not moral,” Mehta explains. “Nobody wants to argue you should be celibate in marriage, so liberal religion begins framing birth control as a tool that allows us to make moral choices about how to structure our families.

“These clergy members believe that you can lay out the evidence for a compelling moral choice and then everybody will want to make a compelling moral choice. They were arguing that this is an access problem and an education problem, and they thought people would see that the best choices for their families are these choices (the clergy members) are suggesting.”

Mehta notes that even the Rev. Martin Luther King Jr. believed that people would make the moral choice if it was presented to them—arguing that big families may be appropriate for the farm, but they work against African Americans’ self-interest in the city. “He laid out the argument that African Americans have a right to these tools as well to lift themselves out of poverty.”

Ultimately, Mehta adds, there was and continues to be backlash on both the right and the left, with the right not anticipating the feminist potential of contraception and the left questioning whether birth control is a tool of liberation rather than of racial and patriarchal oppression.

“And then the center isn’t necessarily super comfortable with prolific non-marital sex,” Mehta explains. “They may be OK with married-like relationships, but they’re generally not OK with an emotionally unencumbered and mutually satisfying one-night stand. And the center wasn’t on board with men needing to pull their weight at home and women being in the workforce and kids being in daycare. We’re still seeing a course correction from the center.”

Documentary shares secrets of the bees

Documentary shares secrets of the bees Rachel Sauer Fri, 04/03/2026 - 08:21

Rachel Sauer

�鶹��Ѱ��Boulder researcher Samuel Ramsey served as science advisor and a producer, alongside executive producer James Cameron, for Secrets of the Bees, premiering this week on National Geographic, Disney+ and Hulu

Would you like to hear a secret about bees?

Not many people know this, but bees in Southeast Asia have figured out that water buffalo dung isn’t the only pungent substance that will keep hornets away.

See, Vespa mandarinia—more sensationally known as the murder hornet—can wreak havoc on a bee colony. One or two dozen hornets can wipe out an entire colony, although bees have developed some pretty awesome defenses. One of these involves vibrating their flight muscles to create a convection oven effect that essentially cooks invading hornets.

However, sometimes a hornet can escape bees’ defenses and flee the hive—but not before leaving a figure-eight pattern of pheromones outside the hive that acts as a beacon to future hornet invasions. Bees deduced that they’d need something even more pungent to spread at the hive entrance to mask the hornet pheromones, “and for a long time we thought they were just relying on water buffalo dung for that purpose,” explains Samuel Ramsey, a �鶹��Ѱ�� assistant professor of ecology and evolutionary biology.

But bees are smart. They figured out they could chew the leaves of an extremely pungent plant to spread at the hive entrance, “which was something we’d never seen before,” Ramsey says.

He and his colleagues discovered this behavior in pursuit of Secrets of the Bees, the fifth installment of the Emmy Award-winning “Secrets of…” series premiering this week on National Geographic, Disney+ and Hulu.

Ramsey, a National Geographic Explorer, served not only as science advisor and featured expert, but as a producer alongside executive producer James Cameron.

Yes, that James Cameron.

“It’s always a pleasure to say I produced a documentary with James Cameron,” Ramsey says with a laugh. “It’s opened up a lot of opportunities to talk with people about bees and together making sure that there’s unity in concept—so we’re not talking in terms of ‘right’ bees and ‘wrong’ bees, but we’re talking about what we can do to support all bees’ survival.”

Communicating science (and bees)

This all came about, in part, because “bees really, really need our help,” Ramsey says, a fact he quickly realized as a lifelong, self-described “bug nerd” observing how human-caused changes to the natural world are affecting bee populations.

During his undergraduate and graduate studies, Ramsey focused on diseases and parasites affecting bees, particularly the Varroa mite, and began raising bees so that he could study them. When he came to �鶹��Ѱ��Boulder, that move included installing a research and observation hive in his lab in the Jennie Smoly Caruthers Biotechnology Building.

Because his research interests also include symbiotic relationships, it’s perhaps no surprise that Ramsey the scientist is also Ramsey the science communicator: passionate about describing the beauty, wonder, fragility and resiliency of the natural world to broad and interested—although often non-scientific—audiences. He has been at the vanguard of using social media to tell the dynamic stories of science.

Thanks in part to this outreach, documentarians and filmmakers began requesting his expertise and consultation. He worked on the documentary My Garden of a Thousand Bees and has discussed insects on NPR, CBS and many other outlets, in addition to becoming a National Geographic Explorer. Still, he says, it’s a little surreal to get that call proposing a collaboration with the director of Titanic and Avatar.

“(Cameron) has 300 hives at his farm in New Zealand, so this really has been a labor of love for him,” Ramsey says.

Making a difference for bees

The framework of Secrets of the Bees is to show a hive of honeybees preparing for winter, but that simple concept took Ramsey and his collaborators around the world, exploring bee colonies as the dynamic cities they are and bees not as mindless automatons, but as intelligent, adaptive creatures that form complex societies.

The filmmakers used groundbreaking technologies, including cameras similar to those used in endoscopes, to peer inside hives for never-before-seen views of bees living, working and playing together. Yes, bees play, Ramsey says, and it’s a wonderful thing to see.

The cutting-edge filmmaking technology allows viewers to see close-up, time-lapse scenes of larva growing into adult bees, as well as the funerary process of pushing dead bees from the hive. “The advent of universal childcare is what allowed this to be one of the most successful species on the planet,” Ramsey says, “which you really see up-close in the film.”

He adds that it was important to him that the documentary not sugarcoat the peril in which Earth’s more than 20,000 bee species currently exist, including calamitous population declines associated with climate change, monoculture crops, parasites, chemical use and habitat loss, among other causes.

“But the film also emphasizes hope, because there are things every one of us can do to support bees,” Ramsey says. “Something as simple as planting a window box with flowers can make a big difference to a lot of bees.”

�鶹��Ѱ��Boulder scholar examines Islam’s most controversial new movement

�鶹��Ѱ��Boulder scholar examines Islam’s most controversial new movement Rachel Sauer Wed, 04/01/2026 - 08:41

Religious studies graduate student Shafiu Alidu went in search of West Africa’s boldest believers in the Yan Hakika Sufi sect

Shafiu Alidu grew up in a unique mixing pot of Islam, Christianity and Sufism in Accra, Ghana. Now a master’s student in the Department of Religious Studies at the �鶹��Ѱ��, he is shedding light on a bold, contested movement that has rattled northern Nigeria’s Muslim communities.

His research invites one to imagine standing in a crowded public celebration in Nigeria as someone nearby leans in and declares openly, and without apology, “Everything and everyone is God.”

For many onlookers, both traditionally devout Muslims and Sufi practitioners, the words might be considered heresy.

Shafiu Alidu, a �鶹��Ѱ��Boulder graduate student in religious studies, researches Yan Hakika, a Sufi movement that has only emerged in the last decade and a half in Nigeria.

This is the world of the Yan Hakika, a Sufi movement that has only emerged in the last decade and a half. Compared to Islam, a religion with more than a millennium of traditions and rules to follow, the Yan Hakika could hardly be more different. The evocative tension between spiritual daring and doctrinal boundaries is part of what drew Alidu to study the group.

“The Yan Hakika caught my attention because they are very bold, and quite controversial—even within Sufism,” he says. “It felt like studying something alive and unfolding right now, instead of just ancient history.”

A long road to Boulder

Alidu’s path to �鶹��Ѱ��Boulder is itself a remarkable story. After completing his undergraduate degree in religious studies, he was awarded a full scholarship to pursue not one but two master’s degrees in Turkey.

It was there that his scholarly voice began to take shape.

“Turkey gave me excellent resources and real intellectual freedom, and it was there that I began publishing academic articles,” Alidu says.

He adds, “That experience deepened my fascination with how spiritual paths blend with local African cultures and inspired me to continue my studies abroad.”

His journey would then bring him to Boulder in 2024 for his third master’s degree, where he now works under the supervision of Aun Hasan Ali, associate professor and associate chair of undergraduate studies.

Alidu recently published a paper on the Yan Hakika in the Journal for the Institute of Sufi Studies.

Boulder, he says, has been the right place to do it.

“Boulder has given me a wonderful new environment to explore these topics even further while staying closely connected to my West African roots,” he says.

Turning up the volume

To understand what makes the Yan Hakika so controversial, one must understand what Sufism is.

Alidu describes it as “the mystical, heart-centered side of Islam,” adding, “Sufis focus on getting close to God through love, meditation, chanting and spiritual training rather than just following rules.”

At the core of Sufi thought is a concept known in Arabic as “Wahdat al-Wujud,” or the “oneness of being,” which holds that there is ultimately only one true reality, and that reality is God.

“The (Yan Hakika) movement attracts many people who feel that traditional religious practice has become too dry or rule-focused. They are drawn to the Yan Hakika’s promise of a more direct, ecstatic and personal experience of God,” says �鶹��Ѱ��Boulder scholar Shafiu Alidu. (Photo: Fatima Yusuf/Pexels)

Alidu offers an elegant analogy.

“Everything else—the universe, the stars, the trees and even you and me—is like a wave on the ocean. The wave looks separate for a moment, but it is made of the same water as the whole ocean and will eventually return to it,” he explains.

Most Sufis hold this idea close, expressing it in private meditation and guarded spiritual language. The Yan Hakika say it out loud.

“It’s like they turned the volume way up on one of the deepest and most subtle ideas in Sufism,” Alidu says.

Heresy or awakening?

Being so forthcoming with their beliefs comes with consequences for the Yan Hakika.

“Both mainstream Sufi groups—especially within the Tijaniyya Sufi Order—and Salafi (strict literalist) Muslims have strongly criticized them, sometimes labeling their beliefs as heretical and even questioning whether they are true Muslims,” Alidu says.

Spilling into real-world actions, that backlash has led to heated public denunciations by prominent religious figures, social boycotts, ostracism and even arrests at social gatherings. And yet the movement keeps growing.

As Alidu explains, for many followers, the Yan Hakika movement offers something traditional practice does not.

“The movement attracts many people who feel that traditional religious practice has become too dry or rule-focused. They are drawn to the Yan Hakika’s promise of a more direct, ecstatic and personal experience of God,” he says.

“In this way, the movement both divides communities and offers some followers a powerful spiritual awakening,” Alidu adds.

This contradiction—threatening and beautiful in equal measure—makes the Yan Hakika impossible to look away from.

Catching smoke with your hands

Studying the Yan Hakika, however, is another matter. Alidu found early on that conventional academic methods go only so far in uncovering the depths of a religious movement steeped in the mystical.

“I was surprised by how much everyday conversation and oral stories—not just books—matter in understanding this group,” he says.

While preparing his latest paper, a turning point came when Alidu immersed himself in accounts of the Yan Hakika’s public gatherings.

“Everything else—the universe, the stars, the trees and even you and me—is like a wave on the ocean. The wave looks separate for a moment, but it is made of the same water as the whole ocean and will eventually return to it.”

“It helped me realize this isn’t just abstract philosophy, but a living, emotional, sometimes chaotic spiritual experience that deeply affects real communities,” he says.

The challenge, he admits, is holding two truths simultaneously. He’s learned to juggle both the scholar’s need for analysis and the community’s need to be understood on its own terms.

“Religious studies gives good tools, but studying something this fluid sometimes feels like trying to catch smoke with your hands,” Alidu says.

Still listening

As for what Alidu hopes to come from his research, the focus is all about people.

“I’m not trying to judge them. I’m trying to understand why their path makes sense to them. I hope they would feel I listened carefully and described their beliefs accurately and respectfully, even when I point out the controversies,” he says.

For readers outside the Yan Hakika, his hopes are broader.

“There is no single way to be Muslim; spiritual paths within the tradition vary widely across cultures and times. Second, even beliefs and practices that appear radical or shocking to outsiders can stem from a deep, sincere longing to experience God more directly and intimately,” he says.

Alidu believes the Yan Hakika movement is a reminder that even one of the world’s largest religions contains intricacies that rarely reach our collective consciousness.

“Understanding groups like them can help us become more open-minded about the rich variety of human spiritual experience in our complex world,” he adds.

Alidu plans to develop his research into a PhD dissertation and, eventually, to teach and write books that make African spiritual traditions and their intersection with Islam more accessible to a wider audience.

In the meantime, he believes that, in a world inclined to flatten Islam into a single story, understanding the intricacies of why people believe what they do is never wasted work.

Under the dome: Why two longtime Boulder residents keep coming back to Fiske Planetarium

Under the dome: Why two longtime Boulder residents keep coming back to Fiske Planetarium Rachel Sauer Mon, 03/30/2026 - 17:49

Bradley Worrell

Although Drew Simon and Ron Marks did not attend �鶹��Ѱ��Boulder, they have a deep appreciation for the university—and for Fiske in particular

When Drew Simon and Ron Marks walk out of Fiske Planetarium after a show, they intuitively know what’s coming next. It’s not applause or conversation or even a specific memory of a particular song or image.

It’s a feeling.

As the two longtime friends step back into the Boulder night, eyes adjusting, ears recalibrating, both of them are grinning from ear to ear. That part never changes.

“Every time we went,” Simon says, “we knew we’d walk out smiling.”

Longtime friends and Boulder residents Ron Marks (left) and Drew Simon are avid fans of the Fiske Planetarium, having attended dozens of shows over the past five years. They’ve seen some shows multiple times.

That quiet certainty—more than any single performance—is what has kept Simon and Marks returning to Fiske for years. Not because they planned to. Not because either of them studied astronomy or worked in the arts or even attended the �鶹��Ѱ��.

And not because they expected to find something transformative inside the planetarium they had driven past many times. Instead, it began with curiosity and a misunderstanding.

Deep roots in the community

Marks, 80, and Simon, 71, have been friends for more than two decades, both with deep roots in the Boulder community stretching back at least four decades. Introduced to each other through a mutual friend—Marks’ housemate—they bonded over shared interests, which include hiking, live music, art and cultural events.

“There was a time when we were probably hippies, or hippie‑adjacent,” Simon says with a laugh. Over that time, �鶹��Ѱ��Boulder has been a constant presence in their life—even though neither man attended the university.

Marks has been retired for several years from a career as an electric engineer for Lefthand Design in Niwot. Simon recently retired from his job as a principal at BSW Wealth Partners in Boulder. Like many longtime Boulder residents, Simon’s relationship with the university grew organically, through connections to the Leeds School of Business and the Conference on World Affairs. Also, his oldest son attended �鶹��Ѱ��Boulder, further weaving the university into his family’s life.

Yet none of that connected either man directly to the Fiske Planetarium. Neither of them had a lifelong fascination with celestial mechanics or immersive films projected on a dome ceiling. Their first visit came the way meaningful discoveries do: by accident.

“As for Fiske specifically, we didn’t have some grand plan. It was probably curiosity,” Simon says, reflecting back. “We may have seen a flyer for the planetarium or something in Boulder Weekly back when that still existed. Or we may have simply asked, ‘What’s going on at the planetarium?’”

Whatever the case, Simon and Marks decided to check it out.

All the pretty lights

Their first show at Fiske remains memorable largely because of how unprepared they were for it. The show listing read “Pretty Lights”—and Simon assumed that meant exactly what it sounded like: a show featuring visually pleasing lights. He had never heard of the musical act called Pretty Lights and didn’t realize it was the stage name of the performer.

“That probably shows how naïve we were at the beginning,” Simon says with a laugh. That misunderstanding says something about where Simon and Marks were at the time. Not insiders. Not trend hunters. Just two curious locals trying something unknown to them.

They saw that first show more than five years ago—and since that time the two men have made up for lost time by seeing as many shows as possible. Still, an exact count is difficult to quantify, Simon says, because the experience resists counting. Some nights, they attend two shows, back to back. At dome film festivals hosted by Fiske, the two men might watch eight or more short films in a day. So, does that count as one event—or eight?

Simon says he’s never kept track “because it never occurred to me that one day someone would ask.” He estimates today that it could range anywhere between 30 and 60 shows.

What he remembers clearly is that—especially in the early years—he and Marks went a lot. They were enthralled.

So many shows to choose from

Marks says the variety of the programming offered by Fiske is a big part of the draw.

“We’ve done all of them,” Simon agrees. “We’ve attended traditional planetarium shows focused on astronomy—black holes, galaxies and large-scale maps of the universe. We’ve done laser shows and we’ve attended a lot of Liquid Sky performances.

“Early laser shows were sometimes underwhelming,” he confesses, “but the technology and the people running it have improved dramatically. Today, I wouldn’t dismiss a laser-only show the way I might have several years ago.”

For Simon and Marks, Liquid Sky performances—the hybrid music-and-visual experiences—have remained their favorite over the years. Simon says that’s because these shows are not canned visuals synced to a soundtrack but instead are created in real time by artists operating sophisticated software during the performance.

Watching the artists (who refer to themselves as “navigators) felt like watching someone paint while the painting formed—”except the brush was digital and the canvas was the dome itself,” Simon says.

Over time, Marks and Simon became familiar faces at Fiske events. After shows, they stayed behind to talk with the navigators, who would ask what they liked about the performance and what might make the event even better. Did a sequence move too fast? Did a visual linger too long? Was there enough variety?

In an informal way, Marks and Simon became in-house critics, always with a focus on helping the experience become better. That sense of exchange and mutual engagement with the navigators deepened their connection to Fiske.

Music was the thread that tied many of these performances together. Simon and Marks say they’ve seen many Fiske shows more than once.

“We’ve seen a lot of Grateful Dead shows—probably more than any other artist. Pink Floyd would be second,” Simon says. “Some of that has to do with our musical preferences, and some of it has to do with relationships with navigators, who would tell us, ‘I’m navigating this show tonight—you should come.’”

“Each performance—even with the same music—felt different,” Marks adds. “The visuals changed. The pacing changed. The interpretation changed, so it was never the same twice.”

A place of musical discovery

Fiske also became a place of musical discovery. Simon says he and Marks had never heard of Tame Impala before attending a Liquid Sky show featuring the band’s music. Since then, they’ve seen that program at least three times.

The planetarium didn’t just reinforce existing preferences—it expanded them, Simon says.

At one point, Simon’s involvement with Fiske crossed a small but meaningful threshold. During conversations with one of the navigators years back, he mentioned that the program could benefit from different music. One idea that emerged from that discussion was a Jimi Hendrix show—and the navigator asked Simon if he’d curate the music. He agreed.

Simon says selecting the tracks, shaping the flow and keeping the program within the typical Liquid Sky timeframe gave him a new appreciation for the craft behind the scenes. The Hendrix show doesn’t run often, but Simon says he considers it a personal footnote in Liquid Sky history.

Film under the dome

If Liquid Sky showed Simon what live‑generated visuals could be, a single dome film revealed what else was possible. That moment came for Simon when Fiske hosted Samskara, a fully produced film by the visual artist Android Jones. Unlike the performances Simon had seen before, Samskara was created specifically for dome presentation. Although the film was only about 35 minutes long, the experience was, in Simon’s words, like going from black‑and‑white TV to color. It completely reframed his understanding of the medium.

“At its heart, Fiske isn’t just about astronomy or music—it’s an immersive experience. It’s an art form that’s still finding its full expression.”

The two men have seen Samskara at least three times. While it was more expensive compared to standard Fiske programming, Simon says he never questioned whether it was worth it.

The film demonstrated that the dome wasn’t just a venue for live experimentation; it was also a legitimate canvas for fully realized cinematic works. That realization carried forward into other film experiences, including Mesmerica and Beautifica by James Hood and collaborators, both of which Simon and Marks saw multiple times.

Then there was Dome Fest West, a judged film festival dedicated entirely to dome films. Fiske hosted it for multiple years, and Simon and Marks attended at least two full festivals, spending entire weekends immersed in the medium. Some films were short and abstract, others narrative or technically focused. There were panel discussions, awards and artists present. For Simon, it was one of the best experiences money could buy.

Fiske audience also evolves over time

Meanwhile, the audience has changed over time.

“When we first started going, there might be 10 people in the entire theater. And sometimes, we were the only ones there,” Simon says. “Now, shows sell out.”

Also, audiences now often applaud between songs—something Simon says would have felt out of place in a traditional planetarium setting.

The environment remains distinctive: everyone seated, the room dark and quiet, eyes turned upward. Simon says he always appreciated when navigators asked people not to use their phones, knowing how disruptive even a small phone screen can be in that darkness. While that messaging has become less consistent, Simon says he finds that audiences are generally respectful and engaged.

So why keep coming back?

Part of the answer is simple: Simon and Marks say they love the planetarium as a resource. Living in a university town is often talked about in abstract terms, but Simon says Fiske represents a tangible way to engage with �鶹��Ѱ��Boulder. Simon and Marks also regularly attend performances through the �鶹��Ѱ��School of Music, and Simon says Fiske feels like a natural extension of that cultural life.

Another part is commitment. Marks and Simon became Fiske members because they wanted to support the planetarium. Membership made them feel connected, not just as consumers of entertainment but as participants in a community invested in what Fiske could become.

And finally, there is fascination.

“At its heart, Fiske isn’t just about astronomy or music—it’s an immersive experience,” Simon says. “It’s an art form that’s still finding its full expression.”

Each visit to Fiske carries the quiet promise that something new will unfold overhead.

“The people at Fiske are wonderful and the programming is thoughtful. And every time we go, we leave smiling,” Simon says. “It’s not hard to say, ‘Let’s go to a planetarium show tonight,’ because we know it will be a meaningful experience.”

Does cannabis cause anxiety? It depends

Does cannabis cause anxiety? It depends Rachel Sauer Fri, 03/27/2026 - 08:54

Blake Puscher

Research suggests that cannabis may cause anxiety when it is strong enough or taken in large enough quantity to produce an immediate effect

Cannabis is an increasingly common drug, with more than 64 million people reporting use in 2024 in the United States alone, according to Statista—more than double the amount in 2010. Despite this, its effects are not well understood. For example, some people use cannabis for relief from anxiety, but there is also evidence that it can cause or worsen anxiety depending on the individual, how much is taken and other factors.

Determining what effect cannabis has on anxiety requires a better understanding of how it affects the endocannabinoid system. To this end, researchers from CUChange (Center for Health and Neuroscience, Genes and Environment), including Renée Martin-Willett, Carillon Skrzynski, Ethan Taylor and Cinnamon Bidwell, with assistance from Jost Klawitter and Cristina Sempio of the University of Colorado Anschutz, assessed the biochemical changes that occurred when people with anxiety took different cannabis products.

Endocannabinoids

The endocannabinoid system is a biological system that extends throughout the whole body. “It’s not just in our brains,” Martin-Willett says; “it’s also in the peripheral nervous system, which is just a fancy way of saying it’s all over the body.”

Renée Martin-Willett (left) and Carillon Skrzynski (right), along with their CUChange research colleagues, assessed the biochemical changes that occurred when people with anxiety took different cannabis products.

The system uses two receptors: CB1 and CB2. In biology, receptors are chemical structures that contribute to a biological effect when they bind with compatible chemical messengers. Whether a receptor and messenger will be able to bind depends on their structure, similar to a lock and key, except that the structure is chemical. When a messenger binds to a receptor and the receptor uses the signal (by relaying or amplifying it, for example), the messenger is considered an agonist—as opposed to an antagonist, which is like a key that fits in a lock but, instead of opening that lock, prevents the correct key from being inserted.

Unlike keys, which either work or do not, chemical messengers can have effects of different strength. For example, THC (delta 9-tetrahydrocannabinol), the main psychoactive component of cannabis, is only a partial agonist of CB1. According to Martin-Willett, CB1 is mostly concentrated in the brain, whereas CB2 is mostly in the gut. The other main component of cannabis is CBD (cannabidiol), which modulates CB1 and CB2, making the effects they produce when activated by agonists weaker without preventing agonists from binding to the receptors.

These chemicals act on the endocannabinoid system because they have chemical structures like endocannabinoids, which are neurotransmitters that are produced by the human body. The two most-studied endocannabinoids are AEA (N-arachidonoyl ethanolamide) and 2-AG (2-arachidonoylglycerol), and they are the focus of this study for that reason.

“2-AG has a really high concentration, and it’s mostly in the brain,” Martin-Willett explains. “It binds with CB1. Then AEA, which has much lower concentrations, is more in the periphery. It’s implicated in implantation and the hormonal cycle for women and is increasingly being linked to anxiety and other kinds of mood disorders.” AEA is associated with positive feelings, and the receptors it binds with, CB1 and CB2, are thought to play a role in whether people view their environment in a positive or negative way. Therefore, AEA may ameliorate feelings of anxiety.

Although some simple facts about the endocannabinoid system are understood, many details remain unexplained. In particular, there is a question as to the effect of cannabis on the endocannabinoid system. This includes how THC and CBD may affect the concentration of AEA and 2-AG in the body, which has implications for what effect cannabis has on anxiety and other aspects of people’s mental state. “Sometimes I tell people the endocannabinoid system is like the Mariana Trench of biomedicine,” Martin-Willett says, “because it was only really discovered in the mid-‘90s. How did we not know about this entire, full-body system until the ‘90s?”

The study

Because this study was intended to determine the effect of cannabis use on anxiety, the participants all had scores on the GAD-7 (generalized anxiety disorder) screener that indicated at least mild anxiety. The participants were split up into four groups: one-fourth of the participants were in the control group (meaning they did not use any cannabis), one-fourth used THC-dominant products, one-fourth used CBD-dominant products and one-fourth used products that combined THC and CBD in a 1:1 ratio.

The study found that the people in the THC-dominant and 1:1 groups had higher AEA levels than those in the control group when cannabis was taken during an acute administration session (meaning in a single dose that is strong enough to produce an immediate effect as opposed to administration over the course of weeks). These results are consistent with the hypothesis that the effects of THC on AEA are caused by competitive binding between the two chemicals at CB1.

“THC might affect AEA in a couple of different ways,” Martin-Willett explains. “THC will bind to CB1 in a ‘normal’ way at the synapse, but it will also permeate the lipid bilayer of the cell itself. The results from our paper support that first idea that THC is competitively binding with AEA at CB1. It is kind of fighting AEA to bind and winning more often than AEA is.”

The basic idea is that whenever THC binds to a receptor, it takes away an opportunity for AEA to bind, causing fewer receptors to be activated by AEA. Even though THC and AEA are both partial agonists of CB1, it is possible that the effects they create upon binding are different. “One idea,” Martin-Willett continues, “is if more AEA makes you less anxious, and in the moment, THC binds competitively with CB1 and keeps AEA from interacting, maybe that is contributing to the paranoia or anxiety after acute use of THC. That is speculative, though. We do not have good human studies on that yet.”

2-AG levels did not change when administered acutely. This could be because 2-AG has higher concentrations in the human body than AEA, making the consequences of introducing THC less significant in the short term. However, in the THC-dominant group, it increased from baseline after two weeks before decreasing to reach a near-baseline level by week four. While AEA is thought to be associated with positive feelings, the association between 2-AG is mostly unknown.

Catching up with the market

Since the Controlled Substances Act of 1971, cannabis has been classified as a Schedule I drug in the United States, which means that it faces special restrictions on the federal level. That may change soon because of the Department of Health and Human Services’ 2023 recommendation that cannabis be reclassified as a Schedule III drug and because of President Trump’s 2025 executive order on the subject. Despite this, and even in states where cannabis has been legalized, the current classification puts limits on studies like this one.

For example, second author Carillon Skrzynski says, “In a lot of our studies, we are not allowed to tell people how much to use, or what to use in some circumstances. That really puts a damper on any kind of causal conclusion.” Ordinarily, scientists keep all variables that could affect the phenomenon they want to understand constant except for one, called the independent variable, which they vary in a controlled manner. This makes the relationship between the independent variable and the phenomenon clear. If multiple variables change at the same time, it becomes almost impossible to say how much each variable contributes to the phenomenon, or even if they would have an effect individually.

“I think there are two really exciting areas that the field needs to move towards,” Martin-Willett adds. “Number one, we need to account for age. We know that the endocannabinoid system changes a lot when we get older. People talk about reduced tone, which just means you have fewer receptors, but we do not really know what that means—if it has a greater effect or a lower effect. And I think the other piece of it is sex assigned at birth. Like I mentioned, more and more the endocannabinoid system is being viewed like the endocrine system, or like the hormonal system, and these things are intertwined, especially AEA and the reproductive system.”

Martin-Willett and Skrzynski both plan to look into these areas. Additionally, their center, CUChange, has multiple studies running and is actively looking for research participants. That is important not only because the different effects of cannabis are unknown, but because it is already being used on a large scale. “A lot of this is really unregulated right now,” Martin-Willett says, “and I think the market is way ahead of the science. People are already using cannabinoids for anxiety, for sleep, for pain, for other kinds of mood problems, and so they can make their voices heard to the government, that this is someplace they want research money to go.”

�鶹��Ѱ��Boulder scientists honored as AAAS fellows

�鶹��Ѱ��Boulder scientists honored as AAAS fellows Rachel Sauer Thu, 03/26/2026 - 08:20

Scholars Rebecca Safran and Tin Tin Su recognized by the American Association for the Advancement of Science for excellence in research, teaching and interpreting science to the public

Rebecca Safran, a professor of ecology and evolutionary biology who has led groundbreaking research on the evolution of new species, and Tin Tin Su, professor and chair of molecular, cellular and developmental biology whose research is leading to novel cancer therapies, have been named fellows of the American Association for the Advancement of Science (AAAS).

The AAAS fellowship is among the highest honors in the scientific community, recognizing a distinguished cohort of scientists, engineers and innovators who “have been recognized for their achievements across disciplines, from research, teaching and technology to administration in academia, industry and government, to excellence in communicating and interpreting science to the public,” AAAS officials note.

“This year’s AAAS Fellows have demonstrated research excellence, made notable contributions to advance science and delivered important services to their communities,” says Sudip S. Parikh, AAAS chief executive officer and executive publisher of the Science family of journals. “These Fellows and their accomplishments validate the importance of investing in science and technology for the benefit of all.”

Rebecca Safran is a professor of ecology and evolutionary biology who has led groundbreaking research on the evolution of new species.

A study of swallows

Safran, whose passion for biology took root in a plant taxonomy class during her undergraduate studies at the University of Michigan, and her research team, study the evolution of new species, focusing on the causes and consequences of individual variation across different scales of time and space.

Because studying the formation of new species can be difficult—given that most species are millions of years old and what caused them to diverge from their ancestors often can’t be determined—Safran and her team study barn swallows, a very closely related group of populations of migratory birds that are currently diverging. This allows Safran and her team to study the process of speciation in real time.

Safran won a National Science Foundation Early Career Development award to study speciation in barn swallows across their entire, expansive breeding range throughout the Northern Hemisphere and Middle East. During the COVID-19 pandemic, when it wasn’t possible to conduct research in other countries, Safran and her research team began focusing on the rapid decline in the population of barn swallows and its implications. For their work, Safran and team study the birds using a highly integrative approach including behavioral, physiological and genetic perspectives.

Among other discoveries, Safran and her team found that sexual selection, or the process by which organisms choose mates based on traits they find attractive, drives the emergence of new species. Her team’s research has been published in more than 120 peer-reviewed journals, including Science, Nature and Current Biology. She also co-edited a recent book on speciation (2024, Cold Spring Harbor Press).

“None of this work is possible without the incredible collaboration with students, colleagues at �鶹��Ѱ��and around the world, private landowers who allow us to study populations of barn swallows on their properties and continuous funding support by the National Science Foundation and other agencies,” Safran says. “I am especially honored to have worked with so many talented undergraduate, graduate and postdoctoral students."

Studying fruit flies to treat cancer

Su, who attended Woodstock School in Mussoorie, Uttarakhand, India, credits her experiences there, in part, with helping her understand that her ideal environment is one in which “you do respect the elders or people who have had more experience or authority. But at the same time, if it doesn't seem right, you question it.”

Tin Tin Su is a professor and chair of molecular, cellular and developmental biology whose research is leading to novel cancer therapies.

Throughout her career, Su and her research colleagues have sought to develop new ways of attacking cancer. Through research on how tissues and organs in fruit flies regenerate after being damaged by X-rays, they synthesized the chemical SVC112, which helps prevent cancer cells from regrowing following radiation exposure. Su and her colleagues focused on the fruit fly because this insect shares more than 70% of disease-relevant genes with humans.

SVC112 is based on the chemical bouvardin found in the firecracker bush (Bouvardia ternifolia) that grows in the Southwest United States and Mexico. Su and her colleagues discovered that bouvardin can prevent regeneration of tissues in fruit flies.

More recently, Su, who also is a member of the �鶹��Ѱ��Cancer Center, and her colleague Antonio Jimeno, co-leader of the �鶹��Ѱ��Cancer Center’s Developmental Therapeutics Program, used SVC112 to target cancer stem cells in head and neck cancers. They are in the process of applying to the FDA to test SVC112 in human trials.

Su also has participated in the �鶹��Ѱ��Boulder Community Perspectives Program, conducting outreach in several rural Colorado communities that led to a research collaboration with Colorado State University Pueblo to assess the effect of heavy metals on the genome in fruit fly and human cells.

“I do what I do because I love science,” Su says. “The potential to help cancer patients in Colorado and beyond makes it even better. So, to be named a AAAS Fellow is really the cherry on top!”

About the AAAS Fellowship

The AAAS began naming fellows annually in 1874, people nominated by the AAAS Council to recognize those whose “efforts on behalf of the advancement of science or its applications are scientifically or socially distinguished.”

Safran and Su join a cohort of more than 80 �鶹��Ѱ��Boulder faculty members who previously received the honor, as well as a broader cadre that includes Thomas Edison, W.E.B DuBois, Maria Mitchell, Steven Chu, Ellen Ochoa and Irwin M. Jacobs.

Young musicians tend to keep playing later in life

Young musicians tend to keep playing later in life Rachel Sauer Wed, 03/25/2026 - 12:38

But their path is not linear, with many starting, stopping and resuming in adulthood; genetics and home environment play differing roles, �鶹��Ѱ��Boulder research finds

Those who played a guitar, piano or ukulele as kids are more likely than average to play as an adult—though perhaps not as likely as you might expect.

That’s one finding of a new study led by �鶹��Ѱ�� researcher Dan Gustavson, which sheds light on how children’s early interactions with music shape—but don’t determine—their musical lives decades later.

The findings, recently published in the journal Developmental Science, draw on nearly 40 years of data from surveys of 1,900 people in The Colorado Adoption/Twin Study of Lifespan Behavioral Development and Cognitive Aging (CATSLife).

�鶹��Ѱ��Boulder researcher Dan Gustavson led a recently published study that sheds light on how children’s early interactions with music shape—but don’t determine—their musical lives decades later.

Gustavson and his colleagues analyzed measures of “music engagement”—being interested in and skilled at musical instruments—of participants at ages 7, 10, 12 and 16, then compared them with the same individuals’ music-playing habits in their 30s. The result: Early music engagement predicts adult instrument playing, but far less strongly than expected.

Many participants started and stopped music throughout adolescence, and some took up music later in life.

“We found more change than stability,” says Gustavson, assistant research professor at �鶹��Ѱ��Boulder’s Institute of Behavioral Genetics. “Kids don’t follow a single linear path. A lot of them start, stop and restart music as they grow.”

The study also highlights shifting genetic and environmental influences. In childhood, shared environmental factors—such as family resources, school access and neighborhood programs—played a major role in determining who “engaged” with music. By adolescence, however, genetic influences grew stronger, probably reflecting teens’ increasing autonomy in the activities they pursue.

“Adolescence is a time where you start to get a lot more freedom over your own behavior,” Gustavson says. “Your interests become less influenced by your parents and more by what you’re exploring. People who are just more naturally tuned to figuring out musical instruments are going to find themselves in those environments more.”

Gender differences emerged as well. Girls were somewhat more likely to engage with music in childhood, though boys showed slightly higher heritability for music engagement at younger ages. These differences disappeared by adolescence.

“Girls were more likely to play music than boys . . . but in boys, there was slightly higher heritability in childhood for music engagement. That actually evened out by adolescence,” Gustavson says.

Playing and listening

Perhaps surprisingly, listening to music in adulthood was largely unrelated to playing music in childhood. Playing and listening appear to be distinct traits. “Passive listening is its own thing,” Gustavson notes. “It doesn’t track neatly with who played instruments as kids.”

“Music may be uniquely positioned to support language development, cognitive growth and even resilience against risky behaviors. But kids can’t benefit from it if they don’t have access,” says �鶹��Ѱ��Boulder researcher Dan Gustavson. (Photo: Dzmitry Shepeleu/Unsplash)

Gustavson is now exploring whether music engagement at key developmental windows—especially around age 12—may help protect teens from later substance use. Preliminary evidence suggests early adolescent music engagement is linked to lower rates of alcohol use and fewer substances tried in late adolescence, five to 10 years later.

He notes that scientists take a developmental perspective on how behaviors can affect health. “You can’t just look at one time point when you want to understand how behaviors relate to important health outcomes. You have to think about the developmental stage. . . . There may be specific windows where things matter a lot more.

“Adolescence is when people start experimenting, and putting yourself in a music environment might be most protective during this time,” he says. Ultimately, Gustavson hopes the research might strengthen arguments for restoring music programs in schools.

“Music may be uniquely positioned to support language development, cognitive growth and even resilience against risky behaviors,” he says. “But kids can’t benefit from it if they don’t have access.”

CATSLife twin studies and other longitudinal twin research help scientists discern the influences of genetics vs. environmental factors by comparing identical twins (who have 100% shared genes) and fraternal twins (with 50% shared genes).

As a student, Gustavson became interested in the power of such studies: “I had friends growing up who were twins, and we always talked about what makes twins similar or different. Taking courses here, I found it really exciting to unpack which aspects of things are explained by genetics and which by the environment.”

Music itself strikes a chord with Gustavson, who plays guitar and drums and was a professional musician for a couple of years before he earned his PhD. “I’ve been really grateful that I’ve been able to integrate this into my research program now.

TikTok doesn’t change minds—it changes moods Rachel Sauer Mon, 03/23/2026 - 17:25

New research from �鶹��Ѱ��Boulder political scientist Michelangelo Landgrave finds that watching political influencers on TikTok does not seem to influence young voters on the issues—but does leave them feeling sadder, angrier and more anxious

If you are over the age of 30, put aside those preconceived ideas that TikTok is just a website where teens and young adults watch 10-second videos of cute cats.

According to the Pew Research Center, about one in five U.S. adults now regularly gets their news from TikTok—and usage is highest among people under age 30. That shift prompted �鶹��Ѱ�� political scientist Michelangelo Landgrave to ask a simple but important question: What does consuming political content on TikTok actually do to young voters?

In a new study published in Political Studies Review, Landgrave and his co-authors found that while TikTok videos from political influencers don’t appear to change young voters’ positions on the issues, they do have an impact—making those viewers feel more negative emotional states, such as anxiety, anger and sadness.

�鶹��Ѱ��Boulder political scientist Michelangelo Landgrave and his research colleagues found that while TikTok political influencers may not change minds, they do change moods.

Landgrave recently discussed the findings of his research paper with Colorado Arts and Sciences Magazine. His comments have been edited lightly for clarity and condensed.

Question: How does this latest study fit into your broader area of research?

Landgrave: I study American politics broadly, including institutions and political behavior. This paper is primarily a behavior study. It was inspired by earlier work examining how exposure to traditional news media—like Fox News and CNN—shapes political beliefs.

We started thinking that traditional media isn’t where many young people get their news anymore. Instead, they’re getting it from TikTok or similar short‑form video platforms like YouTube. It’s arguably the only type of media where the number of people getting news is actually increasing. Traditional media still has an audience, but it’s relatively stagnant and it skews older.

That led us to ask: Does this change in media format affect how people process political information?

Question: At the outset, were you surprised to learn how many younger Americans are getting their news from TikTok?

Landgrave: Somewhat. One of our co‑authors, Robert Anstett, was a student at the time, and we brought him onto the project explicitly because neither I nor the other senior co‑author, Abdelaziz Alsharawy (assistant professor at UT Health Houston School of Public Health), really used TikTok. We had a sense this was happening, but we weren’t firsthand users of TikTok.

We had read a Pew Research Center report noting that an increasing number of people get their news from TikTok, and both of us thought, ‘Isn’t that just a 5‑second clip? What can you really get from that?’

That skepticism helped motivate the study.

Question: When and where was this study conducted?

Landgrave: This study was conducted in 2023 at the University of Missouri while I was finishing my work there. Missouri turned out to be ideal because, while it’s a red state at the presidential level, the local student population was about evenly split—roughly 50% Democrat and 50% Republican. The experiment involved political science students who agreed to participate in the experiment.

Question: How did the experiment work?

Landgrave: At the start of the weeklong study, participants were randomly assigned—regardless of their political views—to one of three groups. One group watched Democratic‑leaning political videos, another watched Republican‑leaning videos, and the control group watched nonpolitical content—mostly animal videos.

We didn’t produce the videos ourselves. These were real TikTok videos that had been popular in the week leading up to the study.

"Because the videos are so short, influencers rely heavily on emotion rather than argument. Both Democratic and Republican videos leaned strongly on negative emotions—sadness, fear and anxiety," says �鶹��Ѱ��Boulder scholar Michelangelo Landgrave.

Question: With political influencer content, did you notice any notable differences in who was producing the content by age, gender or race? What about the frequency of posts?

Landgrave: That surprised us. We expected differences but we didn’t find much. Age, gender and racial diversity were fairly balanced across political sides.

We did observe that Democratic‑leaning influencers produce more videos and tend to have more followers. Both are still dwarfed by nonpolitical content like animal videos, but there is a clear production imbalance. It’s unclear whether that’s due to the algorithm or differences in content creation. We can’t say for sure.

Question: Were there differences in the way Democratic and Republican influencers made their cases to TikTok viewers?

Landgrave: That was one of our most interesting findings. Because the videos are so short, influencers rely heavily on emotion rather than argument. Both Democratic and Republican videos leaned strongly on negative emotions—sadness, fear and anxiety.

Republican‑leaning videos tended to show more negative emotions like contempt and fear. That said, both sides relied heavily on negative emotions. Democratic-leaning videos were more likely to utilize anger. By contrast, traditional news often includes lighter or feel‑good stories, while animal videos found on TitkTok are, of course, just animals being animals.

Question: If the political videos on TikTok are less than a minute, it doesn’t seem like that’s enough time to properly address an issue in a substantive way?

Landgrave: Exactly. Even short television news segments usually provide some nuance and context. There’s a reason it takes 10, 20 or even 60 minutes to follow the news properly. With 5‑ or 10‑second clips, there’s very little room for nuance—you’re really only getting snippets.

Question: After the weeklong experiment, research subjects who watched these influencer videos showed no evidence of changing their opinions on political topics?

Landgrave: That’s correct. We didn’t find evidence that political attitudes changed—even after a full week of exposure. This is important because it wasn’t just one video; the algorithm adapts. Once someone starts watching a type of content, TikTok shows them more of it. So, effectively, we were altering their algorithm for a week—and still didn’t see attitude change.

It’s possible longer exposure—months or years—could matter, but at least over a week, we didn’t see a direct effect on political attitudes.

Question: But you did see emotional effects even at just one week?

Landgrave: Yes. While political attitudes didn’t change, emotional states did. After a week of political TikTok exposure—regardless of whether it was Democratic or Republican—participants reported feeling more sadness, anxiety and anger.

I went into this study fairly ambivalent, assuming concerns were probably overstated. But after seeing the results, I’m genuinely worried about the emotional effects on young people.

Question: Do you believe there are possible policy implications here?

Landgrave: Speaking only as a private citizen, and not representing �鶹��Ѱ��Boulder’s position, I think there’s reason for concern—particularly regarding children and teenagers. While we didn’t find direct political effects, we did find emotional harm.

That suggests policymakers should consider stronger safeguards, whether that’s time limits, improved parental controls or other measures.

Question: Why do you think emotions changed but political attitudes didn’t?

Landgrave: That surprised me, too. We focused on young adults because their political views are still forming. If there were going to be an effect, we expected to see it there.

One possibility is that emotional effects accumulate faster than ideological change. I also wonder whether younger audiences—middle school or even elementary‑age children—might be more susceptible, though that research would require different expertise.

Question: Were your survey participants already using TikTok?

Landgrave: Almost all of them. Only about five participants had never used TikTok. Most already had accounts and varied only in how much they used it. Our intervention didn’t replace their normal viewing—it nudged the algorithm by requiring them to watch specific videos daily.

Question: How confident are you that TikTok itself caused the negative emotional effects, rather than outside life stress?

Landgrave: Because it was an experimental study with random assignment, we’re confident we controlled for most external factors. That said, I’d love to explore conditional effects—whether the impact is stronger for heavy users, rural populations or people with fewer entertainment alternatives.

Question: Do you believe this is a subject area worthy of more exploration, possibly on what longer-term exposure to TikTok might mean for mental health outlook? And maybe whether political influencers have a greater influence over a longer-term period?

Landgrave: Long‑term experimental studies would be very difficult, but observational work is possible. As a researcher—and as a teacher—I’m increasingly concerned about the mental health effects (of social media) on younger people. I see students who seem almost addicted to these platforms, and I worry about my nieces and nephews too.

I want to be clear: This is speculative, but I can imagine an indirect effect over time. Years of exposure to emotionally negative content could potentially radicalize people or increase tolerance for extreme behavior. Our study can’t prove that, but it raises important questions.

Question: If you do more research on this particular subject, what might that look like?

Landgrave: We want to use eye‑tracking technology—glasses that track where people are actually looking. That would help us understand whether viewers are focused on the speaker, the text or even the video at all. Future studies might also involve controlled lab settings to see whether focused attention changes outcomes.

Question: Have you received feedback from other researchers on your published work regarding TikTok influencers?

Landgrave: Yes. Colleagues have reached out, including researchers studying similar effects internationally. This may not be a uniquely American issue—it could be global.

Eyes in the sky focus on elephants

Eyes in the sky focus on elephants Rachel Sauer Mon, 03/23/2026 - 08:22

�鶹��Ѱ��Boulder PhD student Liam Jasperse-Sjolander is helping elephant behavioral observation get off the ground—and into the air above Africa

Walking through the quiet, lush rainforests of Gabon, on Africa’s equatorial west coast, forest elephants have a knack for appearing and disappearing just as quickly.

Because they travel in small groups through the thick jungles, forest elephants are much less noticeable—and thus much harder to observe—than their cousins that live on the wide-open African savannas.

For Liam Jasperse-Sjolander, a �鶹��Ѱ�� environmental studies PhD student, that quiet grace is part of the magic of his fieldwork. “They can be very silent, very unassuming,” he says. “Suddenly you’ll see this gigantic creature in the forest, and the next instant they’re gone.”

Jasperse-Sjolander has spent years traveling through Gabon and other African countries tracking elephant behavior in a variety of ways: using radio collars, camera traps and, more recently, drones.

And he’s been publishing his findings along the way. In 2025 alone, Jasperse-Sjolander co-authored three publications, one based on data from dung collection in Gabon and two on the benefits and potential ramifications of drones in observations.

Now he’s working to collate years of field data collected from these studies—identifying behavioral patterns and their ecological implications—for his dissertation, and pondering what’s next in his research.

Discovering Africa

Growing up, Jasperse-Sjolander didn’t always know where his love of the outdoors would take him. “I just wanted to do something outside,” he says of his childhood in Colorado. “I was either going to work in science or go run off into the woods to fend for myself.”

Ultimately, he chose the former, earning an undergraduate degree in environmental biology from McGill University in Montreal. During those years he got his first taste of fieldwork, spending a semester learning about conservation and field ecology in Kenya, Uganda and Tanzania—and falling in love with Africa. Why?

“From a conservation perspective I think that many areas still feel wild, with so many megafauna worth protecting. And I love the beautiful diversity and vibrancy of cultures and traditions there.”

That’s why, after finishing his undergraduate studies, he headed right back, signing on as a research assistant for a Duke University PhD student Amelia Meier, who was tracking forest elephants in the Wonga Wongué Presidential Reserve in Gabon. Jasperse-Sjolander was eager to get in the field and watch the elephants with his own eyes, and was pleased to see that Meier was interested in mixing old-school observation methods with some new technologies.

“Her approach was really interesting and it kind of opened my eyes to studying behavior in the field in new ways,” he says.

On the ground in Gabon

That approach required a few radio collars—and sorting through an awful lot of dung. Jasperse-Sjolander and his colleagues would track the forest elephants’ movements, then follow along at a safe distance to capture dung samples for later lab analysis.

The data they collected showed the makeup of the fruits and seeds the elephants were consuming in the forest, and laid the foundation for an October 2025 paper published in the journal Oikos. The article sought to model how elephants may play a role in reseeding forests with trees and other large plant species that can consume large amounts of carbon dioxide.

Forest elephants, once thought to be a subspecies of African savanna elephants, were recognized as their own species in 2021 by the International Union for Conservation of Nature.

The results of the study showed wide variety in when and how the elephants disperse seeds, making it difficult to use a one-size-fits-all model for predicting how they will impact their local ecology.

“A lot of climate initiatives will put an emphasis on elephants being ‘gardeners of the forest,’” says Jasperse-Sjolander. These initiatives’ models assume that if elephants are in the area, carbon will in turn increase by a certain amount. “But if that’s not true in a country the size of Gabon, that’s certainly not true on an international scale.”

While there is still more work to do to better understand this interaction, Jasperse-Sjolander’s work in the field was pivotal to reaching this next step in the research.

In the air in Kenya

Now Jasperse-Sjolander is taking his fieldwork to new heights by studying how drones can be used to track elephants’ movements, eating patterns and group sizes—without disturbing the creatures. “This new format opens up a lot of doors for seeing behavior that we haven’t seen before,” says Jasperse-Sjolander.

In 2024 Jasperse-Sjolander was contracted by Save the Elephants, an African non-governmental organization dedicated to the preservation of elephants and their habitats, to analyze how drones may impact different elephant groups. “Before we start using drones to study behavior, we have to make sure that we're not negatively affecting the elephants,” says Jasperse-Sjolander.

Jasperse-Sjolander analyzed the behavioral data Save the Elephants had captured during trial runs of the drones with 14 distinct elephant groups in the Samburu National Reserve in Kenya. The results, which were published in November 2025 in Scientific Reports, were positive: While some of the elephants exhibited a few changes in baseline behavior—like eating a bit less or staying more alert—after multiple trial runs the group seemed generally unphased.

The researchers performing the trials adhered to some general common-sense protocols about how far to stay from the group.

“We always would launch the drone at least a half kilometer away from the group, since it's really at takeoff that it's the most noisy and disturbing,” says Jasperse-Sjolander. “Then we flew at a height of 120 meters (around 400 feet), which is the maximum height you can fly drones in Kenya. So we're basically as far away as we can be.”

Even at that distance, the latest high-tech drones can still capture high-resolution images; researchers can also use the drones’ embedded infrared camera to follow the elephants at night. That camera allowed researchers to follow some elephants for 24 hours and learn more than they ever knew about the animals’ sleep patterns.

“Previously we’d estimated that they only sleep for 15 minutes, but we found that sometimes they’ll all lay down together in a dry riverbed and sleep for a full two hours,” says Jasperse-Sjolander.

“We didn’t really know before what elephants were doing at night,” he adds.. “And so we’re uncovering all these layers of elephant behavior that can help the population.” Knowing where they spend most of their time, when they leave an area and when they are most vulnerable to poaching are all important considerations in the business of saving elephants, he explains.

In May 2025, Jasperse-Sjolander and the Save the Elephants team also published a small field note in the journal Pachyderm about how to maximize these drones’ capabilities, even when there are restrictions on their flight (e.g., in Kenya, where drones are highly regulated). “It can still be a very useful piece of equipment,” says Jasperse-Sjolander, noting that the device’s infrared camera and potential for measuring elephant shoulder height (another common indicator of age) can all be used on the ground, and can take the place of other, more expensive equipment.

In the lab in Colorado

Now, with so much fieldwork data under his belt, Jasperse-Sjolander is back at �鶹��Ѱ��working to finalize his dissertation, comparing behavior between forest and savanna elephants. He’ll build on his master’s coursework (also earned at �鶹��Ѱ��Boulder), which looked specifically at the different behaviors of forest elephants in Gabon—which is 90% forest, 10% savanna—when they’re in the two different biomes.

“Most forest elephant groups are just a mother around their calf and maybe a few relatives,” says Jasperse-Sjolander, explaining that the patchily distributed fruit trees that the elephants feed on are not enough to sustain groups much larger than that.

But, when they emerge from the forest, these groups connect with other small groups.

“Elephants are still very social, and it’s important for them to keep those links and have that larger association network,” says Jasperse-Sjolander, adding that the elephants’ time in the savanna is also important for the exchange of information.

Jasperse-Sjolander’s dissertation will expand the boundaries of his comparison of forest and savanna elephant behaviors to take more of a continent-wide approach to understanding the variations between and among them.

And after that? Jasperse-Sjolander is hoping to head back to Africa for a longer contract with a non-governmental organization like Save the Elephants, where he can use learnings from his PhD to advance our understanding of elephant behavior even further.

“I like just being in Africa and being in the field,” he says. While many researchers in his field go back and forth between the U.S. and Africa, “I like to live and embody the places I study.”
