Inside the Italian art heist: Experts explain the global fight to protect cultural heritage
A lightning-fast art heist in Italy has reignited global concerns about museum security and the protection of cultural heritage. As investigators search for stolen works by some of history’s most celebrated artists, University of Delaware experts are available to help journalists unpack the broader implications. Earlier this month, thieves executed a highly coordinated robbery at the Magnani-Rocca Foundation, stealing paintings by Pierre-Auguste Renoir, Paul Cézanne and Henri Matisse in a matter of minutes. Authorities say the operation was swift, targeted and likely premeditated – highlighting the evolving sophistication of art crime. The theft adds to a growing pattern of high-value art crimes across Europe, raising urgent questions about how institutions safeguard collections and what happens when culturally significant works disappear into illicit markets. UD experts are available to provide context, analysis and on-the-record commentary: Debra Hess Norris Chair, Department of Art Conservation A globally recognized leader in art conservation, Norris specializes in the protection, preservation and recovery of cultural heritage. She can speak to: How museums assess and mitigate security risks What happens after a major art theft The challenges of recovering stolen works in international markets How conservation science supports authentication and repatriation Jessica Horton Associate Professor of Art History Horton’s research examines global art histories and the movement of cultural objects across borders. She can discuss: Why stolen artworks matter beyond their monetary value Cultural ownership, repatriation and ethical considerations How art theft disrupts historical narratives and public access The broader cultural consequences of illicit art trafficking While headlines focus on the dramatic nature of art heists, the deeper story is about the fragility of cultural heritage – and the global effort required to protect it.

New light-based chip boosts power efficiency of AI tasks 100 fold
A team of engineers has developed a new kind of computer chip that uses light instead of electricity to perform one of the most power-intensive parts of artificial intelligence — image recognition and similar pattern-finding tasks. Using light dramatically cuts the power needed to perform these tasks, with efficiency 10 or even 100 times that of current chips performing the same calculations. Using this approach could help rein in the enormous demand for electricity that is straining power grids and enable higher performance AI models and systems. This machine learning task, called “convolution,” is at the heart of how AI systems process pictures, videos and even language. Convolution operations currently require large amounts of computing resources and time. These new chips, though, use lasers and microscopic lenses fabricated onto circuit boards to perform convolutions with far less power and at faster speeds. In tests, the new chip successfully classified handwritten digits with about 98% accuracy, on par with traditional chips “Performing a key machine learning computation at near zero energy is a leap forward for future AI systems,” said study leader Volker J. Sorger, Ph.D., the Rhines Endowed Professor in Semiconductor Photonics at the University of Florida. “This is critical to keep scaling up AI capabilities in years to come.” “This is the first time anyone has put this type of optical computation on a chip and applied it to an AI neural network,” said Hangbo Yang, Ph.D., a research associate professor in Sorger’s group at UF and co-author of the study. Sorger’s team collaborated with researchers at UF’s Florida Semiconductor Institute, the University of California, Los Angeles and George Washington University on study. The team published their findings, which were supported by the Office of Naval Research, Sept. 8 in the journal Advanced Photonics The prototype chip uses two sets of miniature Fresnel lenses using standard manufacturing processes. These two-dimensional versions of the same lenses found in lighthouses are just a fraction of the width of a human hair. Machine learning data, such as from an image or other pattern-recognition tasks, are converted into laser light on-chip and passed through the lenses. The results are then converted back into a digital signal to complete the AI task. This lens-based convolution system is not only more computationally efficient, but it also reduces the computing time. Using light instead of electricity has other benefits, too. Sorger’s group designed a chip that could use different colored lasers to process multiple data streams in parallel. “We can have multiple wavelengths, or colors, of light passing through the lens at the same time,” Yang said. “That’s a key advantage of photonics.” Chip manufacturers, such as industry leader NVIDIA, already incorporate optical elements into other parts of their AI systems, which could make the addition of convolution lenses more seamless. “In the near future, chip-based optics will become a key part of every AI chip we use daily,” said Sorger, who is also deputy director for strategic initiatives at the Florida Semiconductor Institute. “And optical AI computing is next.”

Rip Current Simulations Save Lives
Jase Bernhardt, Hofstra University associate professor of geology, environment, and sustainability and director of meteorology, was referenced in a USA Today article about simulations that teach the public about rip current safety. For years, Dr. Bernhardt has been leading research that offers a virtual reality simulation of being caught in a rip current and teaches ways swimmers can navigate to safety. The development of this technology is supported in part by New York Sea Grant (NYSG).
Ghost sharks grow forehead teeth to help them have sex
Male “ghost sharks” — eerie deep-sea fish known as chimaeras that are related to sharks and rays — have a strange rod jutting from their foreheads, studded with sharp, retractable teeth. New research reveals these are not merely lookalikes, but real rows of teeth that grow outside the mouth. What’s more, the toothy appendage is likely used for mating. Found only in males, the forehead rod — called a tenaculum — is the ghost sharks’ only source of distinct teeth, and it seems to be used to grasp females in much the same way sharks use their toothy mouths in mating. “If these strange chimaeras are sticking teeth on the front of their head, it makes you think about the dynamism of tooth development more generally,” said Gareth Fraser, Ph.D., a professor of biology at the University of Florida and senior author of the study. “If chimaeras can make a set of teeth outside the mouth, where else might we find teeth?” The team, including scientists from the University of Washington and the University of Chicago, studied both fossils and living specimens to solve the mystery. A 315-million-year-old fossil showed the tenaculum attached to the upper jaw, bearing teeth incredibly similar to those in the mouth. Modern chimaeras collected from Puget Sound revealed the same tooth-growing process on the head, seen in modern-day shark jaws. And genetic testing confirmed they expressed the same tooth-specific genes as oral teeth. “What we found is that the teeth on this strange appendage look very much like rows of shark teeth. The ability to make teeth transferred onto that appendage, likely from the mouth,” Fraser said. “Over time, the tenaculum shortened but retained the ability to make oral teeth on this forehead appendage.” Fraser collaborated with Washington’s Karly Cohen, Ph.D., and Michael Coates, Ph.D., from Chicago on the study, which was published this week in the Proceedings of the National Academy of Sciences. As experts in shark evolution and anatomy, the scientists were intrigued by these tooth-filled rods sprouting from the ghost shark foreheads. The central mystery: Is the tenaculum covered in true teeth related to oral teeth or more similar to the tooth-like scales plastering the skin of sharks and some ghost sharks? CT scans of the fossils and modern chimaeras gave the scientists unprecedented, detailed insights into the development of the tenaculum teeth, which looked remarkably similar to the teeth of today’s sharks. The nail in the coffin came from genetic evidence. The tenaculum teeth express genes found only in true teeth, never in shark skin denticles. "What I think is very neat about this project is that it provides a beautiful example of evolutionary tinkering or ‘bricolage,’” said Coates, a professor of biology at the University of Chicago. “We have a combination of experimental data with paleontological evidence to show how these fishes co-opted a preexisting program for manufacturing teeth to make a new device that is essential for reproduction." Cohen, a postdoctoral researcher at the University of Washington’s Friday Harbor Labs and first author of the paper, said scientists had never spotted teeth outside the mouth in this way before. “The tenaculum is a developmental relic, not a bizarre one-off, and the first clear example of a toothed structure outside the jaw,” she said. The bizarre path from a mouth full of teeth to forehead teeth used for mating demonstrates the impressive flexibility of evolution, the researchers say, always ready to repurpose structures for strange and unexpected new uses. “There are still plenty of surprises down in the ocean depths that we have yet to uncover,” Fraser said.
Covering Cuba? Augusta has one of the leading experts ready to help with your coverage
Cuba is facing one of its most severe crises in decades, as compounding economic and energy challenges continue to strain everyday life on the island. Persistent fuel shortages have led to rolling blackouts, transportation disruptions, and reduced industrial output, while inflation and shortages of basic goods have eroded purchasing power for ordinary Cubans. Tourism, once a critical source of foreign exchange, has struggled to fully recover, and the country continues to grapple with declining productivity and limited access to international capital. These pressures have contributed to rising public frustration, increased migration, and a government response that blends cautious economic reforms with efforts to maintain stability. Paolo Spadoni is an ideal expert for journalists covering this evolving situation. As a specialist in Cuba’s political economy, his work focuses on the island’s external sector, including foreign investment, remittances, tourism and the impact of international sanctions. He brings a rare ability to connect on-the-ground developments – such as energy shortages or policy changes, to the broader structural realities shaping Cuba’s economy. With deep academic research and ongoing analysis of current reforms, Spadoni offers clear, credible insight into whether Cuba’s latest measures signal meaningful transformation or simply short-term responses to a prolonged crisis. Paolo Spadoni, PhD, is a widely recognized expert on Cuba and its international relations. He is a tri-lingual political economist with a specialization in international relations and a focus on Latin America’s political and business environments. His research focuses on international relations theories, Cuba's economy and business market, foreign investment in Cuba and U.S.-Cuba relations. View his profile Since this crisis escalated, Spadoni has been the 'go-to' expert for reporters with media from across North America like Reuters, Bloomberg and The New York Times connecting with him for his expertise, input and perspective on the situation. LA TERCERA: “The Cuban tourism sector was already struggling before the Covid pandemic. The best year for international tourism in Cuba was 2017 in terms of foreign exchange earnings. That was the year in which $3.3 billion was collected, and tourism represented 10% of Cuba's GDP at that time. In terms of employment, it provided 120,000 direct jobs and roughly 500,000 indirect jobs. So it played a significant role. That was the best year for international tourism in Cuba, which coincidentally ended in November of that year with the sanctions imposed by the first Trump administration. From then on, tourism from North American visitors began to decline, but European and Canadian visitors were already decreasing,” Spadoni explained to La Tercera. CBC NEWS: "Most of those investments are real estate investments more than tourism investments, meaning the Cuban military has taken possession of prime locations in the best tourism areas of Cuba," said Paolo Spadoni, an associate professor at Augusta University in Augusta, Ga., and co-author of the 2025 book The Cuban Tourism Industry: Evolution, Challenges and Prospects. Columbia Law School: "While seeking to finalize an economic agreement with Cuba, the Trump administration could secure deals across various sectors of the economy. However, tourism holds the most promising opportunities in the short term." Global News (Canada):
Finding joy in learning: How lighthearted moments transform English as a Foreign Language classrooms
In classrooms, not every meaningful learning moment can be planned. At the University of Delaware, educator and researcher Chad Davidson is exploring how spontaneous, lighthearted interactions between teachers and students can open the door to deeper understanding in real time. His recent paper in Language Teaching and Educational Research, "Exploring Spontaneous Acts of Lightheartedness in EFL Classrooms: A Reflective Duoethnography", examines how these unscripted moments – rooted in trust, positivity and a willingness to embrace the unexpected – help create environments where students feel comfortable taking the risks essential to learning. In this Q&A, Davidson discusses the inspiration behind his research, what he’s discovered about these classroom dynamics and how they could shape teaching practices moving forward. Q: What is the focus of this research, and why is it important? Davidson: Spontaneous acts of lightheartedness promote real-time learning because it's being open to the unknown in positive ways since the true dynamic of every classroom brings continuous unknowns: A teacher never knows 100% how the students will react (these students, in these moods, on this day, etc.), how quickly they will learn or pick up on something or not. A teacher, hence, spontaneously responds in real-time to the until-then-unknown student reactions in order for those particular students best to then grasp the concept or skill that is the present goal (or “learning objective”) that those students grasp. The hope is that the teacher's spontaneous response (as it often is with many teachers) is positive and lighthearted in order to foster students to also be open to such unpredictability in the classroom and to foster students' comfortability with the vulnerability to be open to taking spontaneous risks that are necessary for that transformation that we call learning – transforming from lack of knowledge to knowledge, from lack of understanding to understanding, from lack of mastery to further mastery. Q: What are some key findings or developments? Davidson: Realizing the essential features that make up spontaneous lighthearted classroom acts; for example, these acts must include trust of the student(s) and from the student(s), and the acts must have good-intentions of creating or maintaining a relaxed environment conducive to safely taking risks for potential learning. Q: How could this work potentially impact the field or the wider public? Davidson: This could foster this act type in classrooms. That is, hopefully more teacher-practitioners will allow themselves and their students to freely enact these in their daily in-class teaching/learning-attempts. Q: What are the next steps or upcoming milestones in your research? Davidson: We incorporated some valuable insights of Mexican philosopher Jorge Portilla. While there is a glut of usage of German, French, British and American philosophers, there is almost no usage of Hispanic or Latin American philosophers in education literature. It would be great to do more work that makes use of the profound thought in the works of Latin/Hispanic philosophers. For me, this would be continuing to go more deeply in applying Jorge Portilla's thought to philosophy of education, such as to classroom management. ABOUT CHAD DAVIDSON Instructor Chad C. Davidson has a Ph.D. in curriculum and instruction with an emphasis in philosophy of language education.

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.”

Delaware emerges as a test bed for the future of AI in health care
Delaware is positioning itself as a “living lab” where academia, health systems and government collaborate to shape the future of artificial-intelligence-enabled health care. The latest issue of the Delaware Journal of Public Health, guest edited by University of Delaware computer scientists Weisong Shi and Yixiang Deng, brings together 16 articles from researchers, clinicians, policymakers and industry leaders examining how AI and big data are reshaping health care. The issue, debuting this month, balances Delaware-specific topics with broader perspectives, highlighting three levels of impact: what Delaware can expect in the coming years, what other states can learn from Delaware’s approach and how UD research is advancing AI for health through collaborations. “At UD, we don’t work in isolation. We’re working closely with health care systems so that innovation happens together from the beginning,” says Shi, Alumni Distinguished Professor and Chair of UD’s Department of Computer and Information Sciences. Highlights from the issue include: The nation’s first nursing fellowship in robotics – ChristianaCare, Delaware’s largest health system, created an eight-month fellowship to train bedside nurses to conduct applied robotics research. Nurses who completed the program reported higher job satisfaction, improved well-being and greater professional confidence, suggesting programs like this may help retain the bedside workforce and reduce nationwide staffing shortages. Wheelchairs that navigate hospitals on their own – UD researchers developed a prototype autonomous wheelchair that combines onboard sensors and computing with software that interprets spoken directions from users, a step toward moving beyond systems that only work in controlled environments. To operate effectively in health care settings, the researchers say, wheelchairs must be able to navigate crowded hallways, interact with doors and elevators and recover safely when sensors or navigation systems fail. Smarter insulin dosing for type 1 diabetes – Researchers are developing computer models to predict blood sugar (glucose) trends and guide insulin delivery, but must address issues such as noisy data, reliable real-time prediction and the computational limits of wearable devices. A review by UD researchers and colleagues emphasizes the importance of interdisciplinary collaboration, standardized datasets, advances in computational infrastructure and clinical validation to turn these models into practical tools that improve patient care.
