Studying glaciers . . . from Florida

On the surface, the University of Florida seems an unlikely place to find cutting-edge research on ice sheets.

But Emma “Mickey” MacKie says this is the perfect place for her work — thanks in large part to HiPerGator, one of the fastest supercomputers in higher education.

MacKie, an assistant professor of geological sciences and glaciologist, joined UF in August 2021 and said her decision hinged largely on access to HiPerGator and the university’s focus on machine learning and artificial intelligence technologies. MacKie uses machine learning methods to study subsurface conditions of glaciers in polar regions and access to a powerful supercomputer is crucial given the large data sets her research generates.

“I'm very happy to be in a place with lots of people who are working on different types of problems and are interested in developing these different tools,” MacKie said. “There are a number of members of my department in geology who are studying glacial geology through different lenses. And so, there's all of this complementary geological and machine learning knowledge at UF that I'm very excited to bring together.”

MacKie has set up the Gator Glaciology Lab, where she and a team of seven undergraduate students from the fields of geology, computer science, physics, math and data science are using AI to analyze what lies beneath glaciers and how they are moving and melting.

“Our work is part of a bigger effort in the glaciology community to start working on quantifying our uncertainty in future sea-level rise projections so that we can give policy makers this information.”

It’s a very difficult challenge, MacKie said, because of limited access to polar regions and the miles-thick ice covering the ground. Then there is the scale of ice sheets; Antarctica, for example, is the size of U.S. and Mexico combined.

Measurements of the topography below such glaciers are gathered using radars mounted on airplanes to “see” through ice. Her team then uses HiPerGator to simulate realistic looking topography in places where there are gaps or blank spots in the measurements. They generate hundreds of maps to represent different possible ice sheet conditions, which could be used to determine numerous possible sea level rise scenarios.

“Our work is part of a bigger effort in the glaciology community to start working on quantifying our uncertainty in future sea-level rise projections so that we can give policy makers this information,” she said.

Earlier this spring, MacKie swapped out her flip-flops for snow boots to study subsurface glacial conditions in Svalbard, which is next to northeastern Greenland. Visiting Svalbard will help her test and develop data collection and analysis techniques that could be applied to Antarctica or Greenland, which both contain large ice sheets that could have serious environmental impacts if they experience significant melting.

In Svalbard, MacKie and Norwegian researchers from the University of Bergen and the University Centre in Svalbard took seismic and radar measurements of glaciers that will be used to make estimates about conditions beneath the ice.

Among glaciers of concern is the Thwaites “Doomsday Glacier,” which is losing the most ice of any glacier in Antarctica. There are signs showing Thwaites’ ice shelf could start to break in the next few years. MacKie said it will likely be a few hundred years before the glacier could undergo significant collapse and jeopardize the West Antarctica Ice Sheet, leading to several meters of sea level rise.

The effects of Thwaites and other ice sheet melts in Antarctica and Greenland will become apparent in decades to come, with the potential for a meter of sea level rise by the end of the century, which MacKie and other researchers hope to predict more accurately.

“The state of Florida has the most to lose when sea level rises,” she said in an episode of the From Florida podcast. “And so, I think we have a lot of skin in the game and it’s really important to be studying this question here in Florida.”

A year after liftoff: UF scientist reflects on historic space flight and the future of biology beyond Earth

One year after his pioneering flight aboard Blue Origin’s New Shepard rocket, University of Florida space biologist Rob Ferl, Ph.D., is still processing what it meant — not just for his career, but for science itself. “What stands out the most is just the overwhelming gratitude,” Ferl said. “It was such an amazing opportunity for a scientist to go to space and actually do science.” Ferl, a professor in UF’s Horticultural Sciences Department, Director of the Astraeus Space Institute, and Assistant Vice President of Research, became one of the first space biologists to fly alongside his own experiment — a moment that marked a new era in researcher-led missions. His suborbital journey provided a rare opportunity to study how terrestrial biology responds to the very first moments of spaceflight. “For decades, space biology has relied on professional astronauts to carry out experiments designed by scientists on Earth,” Ferl explained. “But to truly understand how biology works in space, I believe you - as the scientist - have to be there. You have to feel the environment.” This September, Ferl and longtime collaborator Anna-Lisa Paul, Ph.D., will be back at Blue Origin’s West Texas launch site, continuing their work with a new series of plant experiments. Ferl and Paul, who directs UF’s Interdisciplinary Center for Biotechnology Research and is a professor in Horticultural Sciences, are tracking fluorescently tagged genes in Arabidopsis plants to study how gene expression changes during the rapid shift from Earth’s gravity to the microgravity of spaceflight and back again. It’s a full-circle moment for Ferl, who remains deeply engaged in the same questions that sent him to space a year ago. Unpacking the Transition from Earth to Space Ferl’s experiment focused on the early metabolic responses of plants during the critical transition from Earth’s gravity to the weightlessness of space. “The scientific community has accumulated plenty of data comparing biology in orbit with that on Earth,” he said. “But we’ve known almost nothing about what happens in those first few minutes as organisms enter space and are exposed to microgravity.” Initial results from the flight reveal intense metabolic changes in the early moments of spaceflight. These changes are distinct from, but connected to, the long-term adaptations seen in orbit. Early Findings, Future Impact While the data from Ferl’s experiment are still on the way to being published, the findings are already shaping the direction of ongoing research. The work contributes to a growing understanding of how terrestrial life, from plants to humans, shares fundamental pathways in responding to the space environment. “This has real implications for the future of space missions,” Ferl noted. “As we send more people and more biology into space in support of exploration, we need a comprehensive understanding of how living systems adapt — right from the start.” Ferl and his team will return to Blue Origin’s launch site in Texas in September to continue their research, sending an uncrewed payload of plants into suborbital space. The flight carries no humans—but it does carry an automated experiment designed to advance their understanding of plant biology in space. It’s part of a broader effort to refine what Ferl calls “researcher-tended missions.” A New Course for UF Space Science The mission has not only shaped the trajectory of Ferl’s research, it has also energized Astraeus and the university’s space biology efforts. “This is about building a new kind of science culture,” Ferl said. “One where the scientists are embedded in every part of the mission, from experiment design to the moment of launch.” As the one-year anniversary of his flight approaches, Ferl remains focused on pushing the boundaries of what science in space can be. But he hasn’t forgotten the magnitude of the moment. “Even a year later,” he said, “the most powerful thing I feel is just: thank you. Thank you for the chance to go, to see it for myself, and to bring that knowledge back to Earth.”

How a UF reading program is reaching classrooms worldwide

For more than 25 years, Holly Lane, Ph.D., has been laser-focused on a global educational goal: to ensure that students worldwide have access to information about reading. Her passion project, known as the University of Florida Literacy Institute, or UFLI, has already improved the literacy skills of more than 10 million children. What began as a modest classroom tool now has a Facebook community of over 273,000 members; 18 million online toolbox views; and more than 500,000 instructional manuals in classrooms. And as the UFLI brand gains traction, Lane continues to champion what the acronym means and why the program has been so life-changing. “When you learn to read, you fly,” said Lane, who serves as the UFLI director and a professor of special education at UF. UFLI is an ongoing effort by UF faculty and students to improve literacy outcomes for struggling students by addressing two key areas: reader development and teacher development. The program began in 1998 as a tutoring model for beginning readers working with Lane’s pre-service teachers. The idea was that, if teachers understood how to employ effective, evidence-based practices in a one-on-one tutoring session, they could transfer those skills to their small-group or classroom instruction. However, some teachers struggled to make that transition, so a dedicated small-group lesson model was created. That foundation eventually expanded into a dyslexia support program and caught the attention of a surprising partner, best-selling author and philanthropist James Patterson. Known worldwide for his literacy advocacy and generous support of reading initiatives, Patterson has become a key benefactor for the program. When the COVID-19 pandemic hit, a challenge turned into a breakthrough. UFLI started its Virtual Teaching Resource Hub and, in the first week, about 70,000 teachers visited the site and downloaded materials. The turning point came when a school in St. Augustine reached out to UFLI, asking for professional development. “I said, ‘Well, what if we planned the lessons for you instead of teaching you how to plan these lessons?’” Lane said. What followed was what Lane called her “accidental phonics program.” “They ended the year with the best scores they'd ever seen, better than their pre-COVID scores, and that was unheard of,” Lane said. That success led to an effective district-wide pilot in Alachua County with 21 elementary schools. UFLI leaders decided to publish the contents of the program and create a manual that individual teachers could purchase. This concept boomed, and the program even made waves overseas. “Starting with the virtual teaching hub… we had a huge following in Perth and in Melbourne, and now we have an Australian edition of the manual,” Lane said. “We’ve been in every state and every Canadian province and territory, but we're also now in something like 60-some other countries.” Patterson has continued his support by directing efforts toward expanding UFLI’s reach in Florida, aiming to bring the program to every district in the state. Looking ahead, Lane is especially excited about UFLI’s new technology. “We're calling it our assessment and planning portal,” Lane said. “Teachers assess two skills a week, and they enter their data into this program and it spits out small-group lesson plans for the following week that target specific needs of their students.” The data input system is highly advanced, requiring the teacher to simply hold up work in front of a webcam, and the system then reads the student handwriting and imports the data. The program’s structure also ensures that students apply new concepts daily and revisit them regularly. But behind it all is a deeply connected community. For Lane, the success of UFLI boils down to people. “We have an amazing team here,” Lane said. “If anything, that's my superpower, finding really good people who are really good humans but also really good at what they do.” For more information about UFLI, visit ufli.education.ufl.edu.

Workplace jargon hurts employee morale, collaboration, study finds

You’ve probably heard it before in a meeting: “Let’s touch base offline to align our bandwidth on this workflow.” Corporate jargon like this is easy to laugh at — but its negative impact in the office can be serious. According to a new study, using too much jargon in the workplace can hurt employees’ ability to process messages, leading them to experience negative feelings and making them feel less confident. In turn, they’re less likely to reach out and ask for or share information with their colleagues. “You need people to be willing to collaborate, share ideas and look for more information if they don't understand something at work,” said Olivia Bullock, Ph.D., an assistant professor of advertising at the University of Florida and co-author of the new study. “And jargon might actually be impeding that information flow across teams.” Age made a difference, though. Older workers had a harder time processing jargon, but were more likely to intend to ask for more information to clarify the message. Younger employees were less likely to seek and share information when confused by jargon. “It gives credence to the idea that younger people are more vulnerable to these workplace dynamics,” Bullock said. “If you're onboarding younger employees, explain everything clearly.” Bullock and her co-author, Tiffany Bisbey, Ph.D., an assistant professor at George Washington University, published their findings Aug. 25 in the International Journal of Business Communication. An expert in communication research, Bullock has long studied jargon’s negative effects for talking about health and science. Then, faced with jargon in her own work, she started to ask how these arcane, technical words might get in the way of a smooth workplace. To find out, Bullock surveyed nearly 2,000 people who were told to imagine they had just started a new job and received an email with important directions. Half had to navigate a jargon-filled message about “intranets” and “EFT” payments. The other half had that jargon translated back into plainer language. The message packed with jargon, not surprisingly, made it harder for people to process the information, which can throw off an entire workday. “It doesn't just make them feel bad about the information they've been given. It makes them feel bad about themselves,” Bullock said. The study then asked people how they would respond to the jargon. The impenetrable language made them feel insecure and less likely to ask for help right when they needed it the most. “They weren’t as willing to collaborate,” Bullock said. “If you can’t ask for more information or share that information downstream, you’re creating silos, and that’s disrupting your workflow and environment.” Having studied jargon for so long, Bullock has one piece of advice for employers and employees alike. “Always reduce jargon,” she said. “The benefit of using jargon doesn’t outweigh the cost.”
