Can Nature Adapt Fast Enough? Mark Urban Explores Whether Ecosystems Can Evolve With Climate Change

As scientists investigate whether an entire Arctic ecosystem can evolve in response to a rapidly warming climate, UConn’s Mark Urban brings leading expertise on the intersection of evolution, biodiversity, and climate change. Climate change is transforming the Arctic faster than almost anywhere else on Earth. Earlier snowmelt, warmer temperatures, and changing waterways are altering habitats and putting new pressures on the plants and animals that depend on them. But what if nature can evolve in response, not simply one species at a time, but as an interconnected ecosystem? That is the ambitious question behind a six-year, $15-million National Science Foundation-funded research project recently featured in The Guardian. Scientists working on Alaska’s North Slope are studying five interconnected species — white-crowned sparrows, feltleaf willow, Arctic grayling, aquatic mayflies, and ground beetles — to understand whether ecological relationships themselves can evolve as the climate changes. It is a question that sits squarely within the expertise of Mark C. Urban, Ph.D., Professor and Arden Chair of Ecology and Evolutionary Biology at the University of Connecticut. Urban is a global expert on the impact of climate change on biodiversity, eco-evolution, and extinction risk. His research integrates ecology, evolution, and genetics to better understand how species and ecological communities respond to environmental change. He has also conducted extensive field research in Alaska, including research involving Arctic grayling and their ability to respond to a rapidly changing climate. Recently, his work was featured in an in-depth piece by The Guardian. “Across hundreds of experiments, we have seen this happening,” says Mark Urban, an evolutionary biologist at the University of Connecticut working on the project. “There is this incredible buffer ability of adaptive evolution.” How the evolution of one species can help the holistic ecosystems depends on how an adaptive trait ultimately translates into ecological properties. For example, if a fish species can quickly evolve, it means that not only is the population maintained, but so is the stream’s productivity. “Any ecological properties that depend on those populations are maintained as well,” Urban says. To get a better idea of whether the Arctic’s stream and tundra habitats will continue to prosper, scientists are mapping the genetic diversity of each of the five study species to see if there is enough to allow for adaptation – influencing the ecosystems’ resilience potential. “We can get so far with ecology, but at some point we want to get down to the basics of why organisms do the things they do, and can they change the things they do,” says Urban. “That’s something only genetics can explain.” Certain genes control the traits associated with succeeding in different environments. “The holy grail in genomics is to find that one gene that affects everything. The gene that rules them all,” he says. “I think that’s optimistic. Most of the traits are going to be determined by hundreds of thousands of genes.”  The Guardian - September 2026 Studies reveal that many plants and animals have been able to persist through evolutionary rescue – the process by which a population on the brink of extinction survives and rebounds through rapid genetic adaptation. Scarlet monkeyflowers in Oregon and California, for example, rapidly evolved during the 2010s to survive a four-year drought. The implications extend far beyond the Arctic. Scientists have traditionally examined how individual species might migrate, acclimatize, or evolve as their environments change. But ecosystems are networks. Fish depend on insects, insects depend on vegetation and water conditions, and predators depend on prey. If those relationships change at different speeds, the consequences can ripple throughout an ecosystem. Urban's work examines precisely these kinds of connections — how ecological and evolutionary processes interact and ultimately influence biodiversity and the resilience of natural systems. His recent research has also examined the growing risk of species extinction as global temperatures rise. The emerging science raises some fascinating questions: How quickly can evolution occur? Can genetic diversity give ecosystems a natural buffer against climate change? What happens when one species adapts faster than another? And are there limits to how much change an ecosystem can absorb before it begins to unravel? As scientists attempt to understand whether nature can keep pace with a rapidly changing planet, Urban can provide valuable perspective on what evolution can — and cannot — do, and what the findings could mean for biodiversity and conservation around the world.

Oil Surpasses $100 as the United States and Iran Conflict Raises Global Stakes

Researchers detail why kissing bug far from home across Atlantic is an international concern

On an August morning last year, an American couple soon to embark on a European river cruise awoke in a luxury hotel in Lisbon. Staring back at them from the headboard was a bloodsucking insect. It wasn’t a mosquito. It wasn’t a bedbug.They wondered: Could it have bitten them while they slept? They’d later learn the culprit was an adult female kissing bug. More than half of all kissing bugs travel with an accomplice — a parasite called Trypanosoma cruzi. The parasite causes Chagas disease which can lead to serious heart problems. T. cruzi is transmitted through the insect’s feces rather than its bite. But how did this particular species of kissing bug, native to the southwestern U.S. and northwestern Mexico for its dry, desert-like climate, get to Portugal? That question became the centerpiece of a scientific investigation led by University of Delaware assistant professor and medical entomologist Jennifer K. Peterson and her team of Blue Hen sleuths. Their findings were recently published in the journal Parasites and Vectors. A bug’s life When the couple returned to their East Coast home, they brought the now-dead specimen with them in a jewelry box. They reached out to Peterson for identification. “When they first contacted me, I was super skeptical,” Peterson said. “My first response was, ‘Is there a Lisbon, Delaware? Because they can’t be referring to Lisbon, Portugal.’” Peterson and colleagues identified the insect as a species of kissing bug, Hospesneotomae protracta, native to the southwestern U.S. and northwestern Mexico. The insect traveled a 5,000-mile transatlantic journey. Could it have stowed away aboard a cargo shipment? Did it hitchhike in somebody’s suitcase and take an international flight? No one knows how it got to Portugal. Portugal imports hundreds of millions of dollars in U.S. agricultural products each year, and more than 2 million American tourists visit the country annually. Any number of pathways could explain its remarkable journey. “This case demonstrates they are hardy enough to survive that journey and then continue on to do what they biologically do, which is, basically, eating,” Peterson said. Six weeks after the incident, the American couple was tested for T. cruzi antibodies, which would indicate exposure to the parasite. The results showed the couple was not infected; their worries were over. But for medical entomologists like Peterson, the case was far from over. Medical entomologists in training Rather than simply presenting the case to her students, Peterson turned it into a collaborative class research project. She gave her class the basic facts and challenged students to investigate the insect’s biology, identify other hitchhiking cases and explore how the kissing bug might have reached Europe. She then combined the strongest elements of their work into one research paper. “Writing, peer review and publishing are such a huge part of being a researcher,” Peterson said. “As university academics, it’s our bread and butter. I wanted students to experience that process from beginning to end.” To Hunt Kinnaird, a UD Class of 2025 environmental science graduate and current master’s entomology student in Peterson’s lab, the case was a great experience in “digital detective work.” “Our job was to explain why this matters and investigate how the kissing bug could have traveled so far,” Kinnaird said. “I looked at global trade. It’s fascinating that either international commerce or human travel can move an insect thousands of miles beyond its natural range.” Increasing awareness The Lisbon case illustrates how easily this insect (and others) can travel across the globe. Peterson said when any insect that can transmit pathogens or parasites journeys outside of its usual range, there can be medical consequences. Especially if the insect is able to lay eggs and start an infestation. In the case of the adventurous kissing bug, it was not carrying the parasite that causes Chagas disease. The next one might. “This particular kissing bug was not infected with T. cruzi, but others could be,” Peterson said. “What we don’t want is to see kissing bug populations in places where they aren’t. Because once that takes off, they’re really tough to eliminate.” She hopes customs officials, border patrol agents and others who monitor for agricultural pests will become more familiar with kissing bugs.

Cybersecurity Meets AI: Preparing the Next Generation for a New Kind of Digital Workforce

Cybersecurity and artificial intelligence are rapidly becoming interconnected – creating new opportunities, new vulnerabilities and a growing need for professionals who understand both. At Augusta University, a new $2 million grant from the National Science Foundation will help prepare the next generation of professionals to work at that intersection. The School of Computer and Cyber Sciences received the award through the NSF’s Artificial Intelligence and Cybersecurity Education Innovation and Scholarship for Service Program. The funding will support Augusta University Government-Ready Experts in Resilient CyberAI, or AUGER CyberAI. Michael Nowatkowski, PhD, professor and director of Augusta University’s Cyber Institute and head of Cyber Programs of Study, is the project’s principal investigator. The program reflects a fundamental shift in cybersecurity education. AI can be used as a tool to strengthen cybersecurity, but AI technologies themselves must also be secured. Augusta University is responding by integrating more AI into its cybersecurity curriculum, rather than treating the two disciplines as entirely separate fields. Participating undergraduate, master’s and doctoral students will take at least four cybersecurity courses and two artificial intelligence courses. Students can receive up to three years of funding covering tuition and fees, along with annual stipends of $27,000 for undergraduate students and $37,000 for graduate students. In return, graduates will put those skills to work in public service, with participants required to work for a federal executive branch agency for the same number of years they receive funding. If federal employment is unavailable, the obligation can be fulfilled through state or local government employment. “As cybersecurity and artificial intelligence become more interconnected, we have a responsibility to prepare students with the knowledge and experience needed to meet the evolving needs of the workforce.” – Alex Schwarzmann, PhD Schwarzmann, dean of Augusta University’s School of Computer and Cyber Sciences, says AUGER CyberAI will allow the university to invest in students while mentoring a new generation of professionals prepared to serve the nation. The first cohort will begin in fall 2026, with approximately seven students expected in the inaugural group and another seven anticipated in 2027.

Canada-U.S. Tariff Dispute Puts Trade Policy and Consumer Costs in Focus

Tariffs between the United States and Canada are again testing one of the world’s closest economic partnerships. New U.S. actions targeting select Canadian imports, along with Canada’s retaliatory measures on certain U.S. products, have moved the dispute beyond trade policy and into the everyday concerns of manufacturers, farmers, retailers and consumers on both sides of the border. The issue also arrives as the United States, Canada and Mexico assess the future of the U.S.-Mexico-Canada Agreement, making trade negotiations a significant government and diplomatic priority. From a government perspective, tariffs are being used as leverage to address market access, domestic production and perceived unfair treatment of national industries. From an economic perspective, however, the costs can spread quickly through integrated supply chains—particularly in automotive manufacturing, steel and aluminum, agriculture, energy and consumer goods. Companies may face higher input costs and greater uncertainty, while households could see higher prices or fewer choices. The central question is whether tariff pressure will produce a negotiated resolution—or prolong a dispute that affects businesses and consumers in both countries. 

25 Years Later: How 9/11 Changed the World

On September 11, 2001, the world watched as nearly 3,000 people were killed in terrorist attacks that would become one of the defining moments of the 21st century. Twenty-five years later, 9/11 remains much more than a moment in history. Its consequences continue to shape the world we live in. The attacks transformed national security and intelligence, changed how people travel, reshaped airport and border security, and ushered in a new era of surveillance and counterterrorism. They also profoundly influenced American foreign policy, leading to wars in Afghanistan and Iraq and decades of debate about security, military intervention and America's role in the world. The effects were cultural as well as political. September 11 changed how a generation viewed safety, terrorism and global conflict. It also sparked difficult conversations about civil liberties, immigration, religious tolerance and the balance between individual freedoms and collective security. For younger generations, 9/11 is increasingly an event learned about rather than remembered. For millions of others, memories of where they were and what they saw that day remain remarkably vivid. A quarter-century later, the anniversary offers an opportunity to remember those who were lost, recognize the first responders and countless others affected by the attacks, and examine how the decisions made in their aftermath continue to influence our world. Experts in history, political science, international relations, national security, terrorism, public policy and sociology can help provide perspective on September 11, its legacy and how the world has changed 25 years later.

Cultivating justice and joy through critical AI use in the K-12 Classroom

Inspired by her middle school social studies teacher, University of Delaware Associate Professor Stephanie Smith Budhai has always believed that a classroom should be a space where students feel valued and nurtured. As a seasoned educator, she has helped teachers create these spaces using technology to support students in meeting learning outcomes, developing their skills and growing their confidence. Now, Budhai is mentoring overwhelmed teachers to reclaim the classroom as a nurturing environment for all students. Her book, "Critical AI in K-12 Classrooms: A Practical Guide for Cultivating Justice and Joy" with co-author Marie Heath of Loyola University Maryland, supports teachers and students as they navigate the complicated interactions of AI, education and justice. Budhai answered pressing questions about the already popular book. How would you describe the central message or takeaway of this book? "I believe that classrooms should be joyous spaces where all students feel heard, valued, seen and loved. Dealing with powerful technologies that exacerbates the biases and harms of society such as AI can impact teachers’ ability to nurture such spaces. Thus, this book was written to provide a practical guide for teachers and students as they navigate the complicated interactions of AI, education and justice. It is our duty as educators not to dismiss the technology altogether, but to help teachers take a critical lens, as they use AI for teaching and learning." What inspired you to pursue this line of research? "Before writing this book, I had already published 8 books and over 80 practitioner articles around technology, equity, teacher education and leadership. There had been other books that were quickly published about AI, but none focused on the harms of AI, how teachers could come to understand how AI really works and use it in ways that do not harm students." What are some of the key ways that K-12 teachers can cultivate justice and joy through AI? "In the book, we have many examples of how to cultivate justice and joy. For example, in chapter 3, we provide strategies for teachers to build an equity-mindset while supporting students in developing a critical consciousness around AI technologies, which are inherently biased. In chapters 4 and 5, we provide framing for using culturally-sustaining, abolitionist and fugitive pedagogies in designing curricula and learning activities that include the just use of AI technologies. And, in chapter 6, we provide teachers with myriad personal, professional, pedagogical and participatory actions they can take when using AI for teaching and learning." How could this work impact schools, teacher education programs and the broader public? "This work was created to support K-12 teachers, and many teachers have already shared how it has impacted them. K-12 teachers can immediately put the strategies and learning activities that we suggest in the book to use. We also situate AI in longer histories of technology injustice and provide accessible content on understanding how AI works through a critical algorithmic literacy perspective. Teacher education programs can use this work as they prepare teachers to navigate the complicated intersections of teaching, AI and justice. For the broader public, we also include content on justice-centered community activities and projects that are focused on critical AI." About Stephanie Smith Budhai Stephanie Smith Budhai is an associate professor in UD’s College of Education and Human Development, specializing in educational technology. Her interdisciplinary research and practice lies at the intersections of technology, equity and civic engagement, across myriad K-16 settings. She has published 10 books on teaching and digital technologies. Among other professional appointments, she serves as the Chair of the Information Technology Council for the Society for Information Technology and Teacher Education and is on the Board of Directors for the Civics of Technology.

How Teachers Are Incorporating the 9/11 Anniversary in Their Classes

Alan Singer, professor emeritus of learning, teaching, and technology, appears in a Newsday article about how teachers are approaching the 25th anniversary of 9/11 in their classrooms. “For the generation that lived through 9/11, it was a day that will live in infamy,” he said. “But for [younger] people, it may not. So the question then becomes, what do we want kids to learn about 9/11?”
