A.R. Siders


A.R. Siders, core faculty with the University of Delaware's Disaster Research Center, is one of 500-plus experts who developed the Fifth National Climate Assessment (NCA5), the preeminent source of authoritative information on the risks, impacts and responses to climate change in the United States.


Leaders and practitioners highlighted the findings and raised awareness of climate impacts and solutions at a release event on Nov. 14. White House and climate leaders from across the country elevated the key themes of NCA5 and further highlight the Biden Administration’s whole-of-government approach to mitigating and adapting to climate change.


Siders focuses on managed retreat, which is the purposeful movement of people, buildings and other assets from areas vulnerable to hazards. She also specializes in climate change adaptation decision-making and evaluation in general: how and why communities decide when, where, and how to adapt to the effects of climate change and how these decisions affect risk reduction and equity outcomes.


Joining Siders on the NCA5 were Jing Gao, Assistant Professor of Geospatial Data Science, and Kimberly Oremus, assistant professor of marine science and policy.

The science behind the blood moon: Understanding this lunar phenomenon ahead of march's event

March's celestial event – a blood moon – is just around the corner. This captivating lunar spectacle isn't just a cool sight to behold; it has some neat science backing it up. The blood moon phenomenon happens during a total lunar eclipse. "During a total lunar eclipse, the only light that reaches the surface of the moon is refracted through the Earth's atmosphere, which essentially acts like a lens. Light is a wave, and every color of the rainbow has a different wavelength – red the longest and violet the shortest," said Bennett Maruca, associate professor of physics and astronomy at the University of Delaware.  What adds to the excitement is the rare nature of total lunar eclipses. While partial eclipses occur more frequently, a full blood moon isn't an everyday event. Depending on where you live, the blood moon may only grace the night skies a few times a decade. "One of my favorite things about total lunar eclipses is that it's hard to know ahead of time quite what it will look like. The moon can take on a color ranging from burnt orange to red to grayish brown," he said. "The closer the Moon passes to the center of Earth's shadow, the darker the color will be."  Maruca is available to speak about the event, which takes place in the wee hours of March 3. He can discuss when to wake up to see the phenomenon and how to best capture it.  "For photographing the moon, I would recommend a camera with some optical zoom – the moon is only about 0.5 degrees across. Because of the low lighting conditions, a tripod or other support would be helpful since a longer exposure time will be needed," he noted.  He has appeared in a number of outlets including Mashable and The Philadelphia Inquirer. He can be contacted by clicking on his profile.  ABOUT BENNET MARUCA Bennett Maruca serves as an associate professor in the University of Delaware's department of physics and astronomy. His research focuses on the sun, the solar wind and other space plasmas. He is a recipient of the Antarctic Service Medal and NASA's Silver Achievement Medal. He also serves as an associate director of the Delaware Space Grant Consortium and is currently mentoring over twenty undergraduate students developing experiments to fly into space to observe Earth's ionosphere.

Discovery pinpoints potential Achilles’ Heel in HIV, opening new frontier in drug development

Scientists have long known that detecting HIV early is crucial in slowing and treating the virus. During the acute stage of infection, a single human cell can produce as many as 10,000 new HIV particles. A discovery led by the University of Delaware's Juan Perilla offers hope: A new drug target early in the virus's life cycle that could save millions of lives. In the surprising discovery, published Feb. 18 in Nature, Perilla and collaborators in the U.S. and the United Kingdom, have revealed a previously unknown role for the viral protein integrase. Scientists already knew that integrase helps HIV insert itself into human DNA. But this new study provides the first direct evidence that integrase plays a critical structural role earlier on in HIV’s life cycle — when the virus matures into an infectious force. Using high-resolution cryo-electron microscopy (cryo-EM), the research team – which also included UD doctoral student Juan S. Rey – found that integrase proteins form gluey filaments that line the inside of the capsid. Each segment of the filament slots neatly into the capsid’s hexagon-shaped tiles, while gripping tightly to HIV’s RNA genome. This zipper-like arrangement organizes and packs the virus, preparing it to hijack a cell and start making copies of itself. “Integrase plays a structural role inside the HIV capsid — nobody expected that,” Perilla said. “This protein forms filaments that anchor the RNA to the capsid. Without these filaments, the virus is non-infective.” Seeing inside HIV is no small feat. The capsid is only about 120 nanometers wide —roughly 1/800th the thickness of a human hair. It is incredibly small, fragile, densely packed and constantly changing, Perilla said. To reveal its hidden architecture, the researchers relied on deep collaboration and a combination of sophisticated microscopy, molecular modeling and experimentation. Read more about the science behind the study here. “The thing with HIV is that people are chronically living with it,” Perilla said. “Treatments are effective, but patients always need new therapeutics. We want to help develop the next generation of inhibitors and hope to have a significant contribution.” To reach Perilla directly and arrange an interview, visit his profile page.

Rethinking AI in the classroom: A literacy-first approach to generative technology

As schools nationwide navigate the rapid rise of generative artificial intelligence, educators are searching for guidance that goes beyond fear, hype or quick fixes. Rachel Karchmer-Klein, associate professor of literacy education at the University of Delaware, is helping lead that conversation. Her latest book, Putting AI to Work in Disciplinary Literacy: Shifting Mindsets and Guiding Classroom Instruction, offers research-based strategies for integrating AI into secondary classrooms without sacrificing critical thinking or deep learning. Here is how she is approaching the complex topic.  Q: Your new book focuses on AI in disciplinary literacy. What is the central message? Karchmer-Klein: Rather than positioning AI as a shortcut or replacement for student thinking, the book emphasizes a literacy-first approach that helps students critically evaluate, interrogate, and apply AI-generated information. This is important because schools and universities are grappling with rapid AI adoption, often without clear guidance grounded in learning theory, literacy research, or classroom practice. Q: What inspired this research? Karchmer-Klein: The book grew directly out of my work with preservice teachers, practicing educators, and school leaders who were asking practical but complex questions about AI: How do we use it responsibly? How do we prevent over-reliance? How do we teach students to question what AI produces? I also saw a gap between public conversations about AI which often focused on fear or efficiency and what teachers actually need: research-informed strategies that support deep learning. My long-standing research in digital literacies provided a natural foundation for addressing these questions. Q: What are some of the key findings from your work? Karchmer-Klein: AI is most effective when it is embedded within strong instructional design and disciplinary literacy practices, not treated as a stand-alone tool. The research and classroom examples illustrate that AI can support student learning when it is used to prompt reasoning, reveal misconceptions, provide feedback for revision, and encourage multiple perspectives. Another important development is the emphasis on teaching students to evaluate AI outputs critically by recognizing bias, inaccuracies, and limitations, rather than assuming correctness. Q: How could this work impact schools, teacher education programs and the broader public? Karchmer-Klein: For educators, this work provides concrete, evidence-based literacy strategies coupled with AI in ways that strengthen, not dilute, student thinking. For teacher education programs and school districts, it offers a research-based framework for professional development and policy conversations around AI use. More broadly, the work speaks to a public concern about how emerging technologies are shaping learning, helping to reframe AI as something that requires human judgment, ethical consideration, and strong literacy skills to use well. ABOUT RACHEL KARCHMER-KLEIN Rachel Karchmer-Klein is an associate professor in the School of Education at the University of Delaware where she teaches courses in literacy and educational technology at the undergraduate, graduate, and doctoral levels. She is a former elementary classroom teacher and reading specialist. Her research investigates relationships among literacy skills, digital tools, and teacher preparation, with particular emphasis on technology-infused instructional design.
