National Cancer Research Month: Baylor Researchers at Forefront of New Discoveries

May is National Cancer Research Month, which highlights the importance of lifesaving research to the millions of people around the world affected by cancer. Thanks to spectacular advances made by cancer researchers, approximately 18.6 million people in the United States and millions more worldwide are living with, through and beyond their disease. Over the past year, Baylor University Media and Public Relations has reported on Baylor research at the forefront of discovering novel approaches to effective cancer therapies. University researchers are using tumor starvation techniques, natural products, phages, modified bacteria, precision nutrition and more in their trailblazing work on some of the most aggressive cancers, including kidney, pancreatic, oral, colorectal and breast cancers. In a recent article published by the University, it featured the hard work and research of eight Baylor experts driving those discoveries forward: • Kevin G. Pinney is developing a next-generation treatment for kidney cancer that targets the blood vessels feeding tumors. His research focuses on specialized drug conjugates designed to cut off oxygen and nutrients to renal cell carcinoma tumors — essentially starving cancer cells to death. • Daniel Romo is accelerating new therapies for pancreatic cancer using compounds derived from marine natural products. His work on a simplified version of pateamine A could offer a new therapeutic pathway for pancreatic ductal adenocarcinoma, one of the most aggressive and difficult-to-treat cancers. • Joseph Taube is investigating how breast cancers spread and resist treatment. His recent work examines whether a natural compound called Ophiobolin A can trigger inflammatory forms of cancer cell death that may work alongside immunotherapy — particularly in treatment-resistant triple-negative breast cancers. • Leigh Greathouse is combining cancer biology, nutrition science, and AI to personalize cancer prevention and treatment strategies. Her research explores how diet and the gut microbiome influence cancer outcomes and survivorship. • Michael S. VanNieuwenhze is leading groundbreaking colorectal cancer research using modified bacteria to deliver cancer-killing proteins directly into tumor cells. His team is engineering Listeria monocytogenes as a targeted therapeutic delivery system. • Aaron Wright is helping lead a major ARPA-H initiative exploring the use of bacteriophages — viruses that attack bacteria — to reshape the human microbiome and improve health. The project could eventually help prevent diseases linked to oral and colorectal cancers through low-cost phage-based treatments. • Savannah Rauschendorfer is researching how exercise interventions may reduce the harmful cardiac side effects of chemotherapy in adolescent and young adult cancer patients. Her work aims to identify patients at risk of cardiotoxicity earlier and improve long-term survivorship outcomes. • Jonathan Kelber studies the cellular and molecular mechanisms behind aggressive breast and pancreatic cancers. Through his Developmental Oncogene Laboratory, Kelber investigates how cancer cells evolve during tumor progression and tissue regeneration. Together, these researchers showcase how cancer science is rapidly evolving beyond traditional treatments – integrating biology, chemistry, nutrition, exercise science, microbiome research, and artificial intelligence in the search for more effective and personalized therapies.

Approximately 4,400 degrees conferred during Georgia Southern’s 2026 Spring Commencement ceremonies

Last week, approximately 4,400 graduates from Georgia Southern University’s Statesboro, Armstrong, Liberty and Swainsboro campuses received associate, baccalaureate, masters, specialist and doctoral degrees in five Spring 2026 Commencement ceremonies. Georgia Southern President Kyle Marrero welcomed the graduates and their guests to the ceremonies, held at the Allen E. Paulson Stadium and Jack and Ruth Ann Hill Convocation Center in Statesboro, Enmarket Arena in Savannah and East Georgia Campus in Swainsboro on May 11, 13 and 14. “To our graduates, congratulations,” Marrero welcomed the crowds. “Today we recognize and honor your hard work, perseverance and personal growth throughout your academic journey. The road to this moment has not been without its challenges, and your presence here is a reflection of your dedication, resilience and strength. You have every reason to be proud. This commencement is a meaningful milestone not only for each of you personally, but for the entire Georgia Southern community.” The Commencement speakers included: Bob Somers (’83) Nick Westbrook (’20) Berry Aldridge (’15) Kim Hartsock (’20, ’21) Rep. Butch Parrish Somers opened the ceremonies at Paulson Stadium with words of encouragement for the new graduates. “While this day marks your formal education coming to a close, the truth is your education and life is just now beginning,” he said. “When I look out at you, I don’t look at graduates. I see future leaders. And our future is bright because of what you’re going to bring to this world. “Georgia Southern gave me structure, opportunity and people who believed in me. One of my proudest moments was graduating from this incredible institution. Find your north star. What kind of person are you? What are your values? Be genuine with yourself and others. If you’re authentic, people will trust you and they will follow you. Be comfortable being uncomfortable. Real leadership requires vulnerability.” Westbrook relayed the importance of service and character alongside leadership. “You will have the opportunity to influence people, organizations, companies and industries,” he said. “Use that influence for good. Your opportunity will not only be for a better job, more income or a higher position. The highest calling of your opportunity will be what you can do for the people who are affected by your influence. In a world that is becoming increasingly transactional, be the leader that goes the extra mile to make your world a little more relational, more kind, more human.” Aldridge enthusiastically challenged graduates to consistently recalibrate the way they think, and to consciously surround themselves with support. “Class of 2026, you’ve accomplished something incredible, but you’ve done it during a very strange and chaotic time in history,” he said. “I’m not breaking any news when I say that we are standing on the edge of a massive change to our jobs, our technology, our society. “I don’t know how AI is going to change the way we work or influence the job market. I challenge you to be skeptical even in your own most passionately held beliefs. That’s the only way to keep ourselves in check, and it’s the only way to keep ourselves growing. Nurture three types of relationships — one who lifts you up, another who tells you the truth, and one who will always show up — in order to succeed, he continued. And then be that person for others. Hartsock reflected on the generational impact of earning a degree. “For some of you, this is not just a personal achievement, it’s a historic one,” she shared. “You may be the first in your family to earn a college degree, and that accomplishment carries special significance. You are changing the trajectory of your family and setting an example for generations to come.” She asked them to be intentional about who they learn from. “Seek out people who can teach you things that books never will,” she said. “It’s important to look for leaders whose lives are marked not only by achievement, but also by joy and purpose. “Invest in this university. Join the alumni association. Help recruit future Eagles. Create a scholarship. Create opportunities for students to learn from you and work with you. Stay involved,” she said. “You never know, 25 years from now, you might be standing right here where I am. Congratulations, class of 2026 and Hail Southern!” In the closing ceremony in Swainsboro, Parrish encouraged graduates to continue learning. “Today is by no means an end,” he said. “It’s just the beginning. Your education has prepared you for what lies ahead. Your education allows you to create your own path forward. You have a unique opportunity to define your own path. You don’t have to follow anymore. Education is like insurance for whatever you’ll be facing in the future. “Education comes in many forms. There’s formal and informal, traditional, nontraditional and learned education, just to name a few. So, I encourage you to pursue a career in something that you really have a passion for and something that you really want to do. Whatever you decide to do is up to you, and your future is bright and it’s unlimited.” Video and Photo Links Spring 2026 Commencement ceremony 9 a.m. video on May 11 in Statesboro Spring 2026 Commencement ceremony 6 p.m. video on May 11 in Statesboro Spring 2026 Commencement ceremony video on May 13 in Savannah Spring 2026 Commencement ceremony video on May 14 in Statesboro Spring 2026 Commencement photos here Credit: Courtesy of Georgia Southern University Georgia Southern University, a public Carnegie Doctoral/R2 with a Carnegie Community Engagement classification, offers approximately 149 different degree programs serving nearly 31,600 students through 11 colleges on four campuses in Savannah, Hinesville, Statesboro, Swainsboro and online instruction.

Survey says: Senior leaders are using AI, but they could use more direction

Over the years, study upon study has shown that senior leaders are slower to adapt to new technology – email, the Internet and social media – than younger employees. That’s not necessarily so with AI, according to the University of Delaware’s Saleem Mistry. Mistry, associate professor of management at UD's Alfred Lerner College of Business & Economics, recently conducted a survey of more than 200 university alumni, 75% of which had more than 16 years of professional experience. He found that senior leaders are actively adopting AI to solve their biggest challenges. However, they are doing so largely without structured support or guidance. Here are four findings from Mistry's survey that shows how AI is actually being used at the top. Senior Leaders Are Overwhelmingly Self-Taught Mistry said his most glaring finding is the gap between high AI adoption among senior leaders and the near-total absence of formal corporate support. Although a majority use these tools, they are almost entirely self-taught, which highlights visible opportunity that organizations aren’t really steering the AI conversation for leaders: • High usage. 62% of all senior leaders surveyed use AI tools "regularly" or "occasionally" in their work. • Training gap. Of those users, an overwhelming 80% report their organization provides "Never" or only "Sometimes" (mostly never) adequate training. Mistry said this shows that leaders from VP level down are using tools like ChatGPT and Copilot informally to keep up with heavy workloads, without any real organizational guidance. The stakes are high. In the survey, a vice president of legal was using AI for compliance tasks and a manager of three was using it for performance reviews, both with no formal training. “These are senior leaders handling sensitive work while essentially figuring it out on their own,” Mistry said. There is a clear ladder of AI use Leaders are not using AI randomly. There is a clear progression in how they use it, moving through three levels. • Tier 1 (The Drafters) This is the most common starting point. Leaders use AI to improve writing and communication. They draft emails, shape documents, and refine tone. As one Director of Product put it, it helps him "polish phrasing" and adjust tone and voice. • Tier 2 (The Synthesizers) At this stage, leaders use AI to manage information overload. They summarize meetings, condense documents, and pull together research so they can keep up with large volumes of input. As one leader managing a team of 200 said, "Being a leader requires attention in a variety of areas. AI helps me manage the vast amounts of information I need to consume." • Tier 3 (The Architects) Here, leaders move beyond writing and summarizing. They use AI to automate parts of their work. This includes building agents, creating custom GPTs, or designing tools that track work and performance. One leader managing 300 people said, "It will eliminate half or more of my overhead." Managers and individual contributors use AI for different reasons People managers and individual contributors (IC) are using AI for very different reasons based on their roles. • For people managers, their main challenge is scale. They are overloaded with communication and administration, so they use AI to reduce noise and keep up. They lean heavily on summarization and tone adjustment tools. • For project leads and ICs, their focus is output. They use AI to produce work faster, including drafting content, building decks, writing code, or generating ideas. This difference reflects their jobs. One group is trying to keep up, the other is trying to produce more. It also shows that AI is not a single-use tool. Its value depends on the problem it is being used to solve. This difference reflects their jobs. One group is trying to keep up, the other is trying to produce more. It also shows that AI is not a single-use tool. Its value depends on the problem it is being used to solve. Resistance to AI is mostly intentional Among the 38 percent of leaders who do not use AI, resistance is usually not based on lack of awareness. It falls into three groups: • The Ethical Objectors. Some avoid AI due to concerns about its broader impact. • The Quality Skeptics. Some do not trust the output and feel it is not reliable enough for important work. • The Blocked. Some are not allowed to use AI due to company policy. Mistry concludes that there is a clear overall pattern: Leaders are using AI in practical ways, but mostly without structured support or guidance. “If it feels like you are figuring this out as you go without much help from your organization, that is consistent with what most leaders are experiencing,” Mistry said.

How the Class of 2026 can keep resumes out of the digital black hole

Students set to graduate this May are entering a job market where the rules of engagement are being rewritten in real-time. AI is both friend and foe, and ghosting has become the norm. University of Delaware career expert Jill Panté shares how college students can navigate these challenges in a rapidly shifting economy. Panté, director of the Lerner Career Services Center at UD, can apply her expertise to the following: The AI recruitment gap • How to prevent resumes from falling into the "digital black hole" of automated tracking systems. • Current recruitment in 2026 is heavily filtered by AI. If resumes don't mirror the language of the job description, a human might never even see it. • In 2026, AI is the gatekeeper. Students who aren’t using AI for assistance are working twice as hard for half the results. However, the goal is to use it as a co-pilot, not an autopilot. Beat the bots (tailor your content) • Use tools like Resume Worded or Generative AI like Microsoft Co-Pilot or Gemini to see how resumes stack up against specific job postings. • It is better to send five highly tailored, thoughtful applications than 50 generic ones that get auto-rejected by an algorithm. • Use AI to run a mock interview based on the job description and company. The "hidden” job market • If a "job search" consists solely of clicking "Easy Apply" on LinkedIn for six hours a day, it’s not searching; it’s just doom-scrolling with a resume. Roughly 80% of your time should be spent talking to humans. The other 20% should be spent on applications and research. • Find the recruiter or a department head on LinkedIn. Send a brief (2-3 sentence) note reiterating your interest. • Leverage alumni networks through LinkedIn. Narrative branding • Especially for Gen Z: Hiring managers don't just want to know what you did; they want to know the impact you made. • Instead of saying "Responsible for social media,” say "Increased engagement by 40% over 3 months by implementing a new video strategy." • Always lead with results (LinkedIn, resume, Interviews) to showcase the value you bring. Workforce anxiety • Managing the mental toll of the modern, high-speed job search and the professional "ghosting" epidemic. • Establish a personal "Board of Directors" to provide a balance of support, accountability and feedback. • Maintain momentum by volunteering, attending local networking events and learning new skills on platforms like LinkedIn Learning and Coursera.

Pope Leo XIV Faces Both Historic and Novel Challenges as He Enters the Second Year of His Papacy

In his first appearance on the balcony of St. Peter’s Basilica, Pope Leo XIV shared with the world a message of hope, communion and reconciliation, emphasizing the need to “build bridges with dialogue and encounter so we can all be one people always in peace.” Throughout the last 12 months, the Pontiff has placed these values at the forefront of his work and ministry, pairing active collaboration with prayerful contemplation in his leadership of the world’s 1.4 billion Catholics. In the coming years, that emphasis is likely to continue, as the Pope addresses longstanding rifts and evolving challenges within the Church and beyond. Asked to consider the most striking aspects of his early papacy, and to reflect on the most pressing issues he currently faces, Villanova faculty members studying the pontificate had a wide variety of responses. Jaisy A. Joseph, PhD Assistant Professor of Theology and Religious Studies For Dr. Joseph, Pope Leo’s first year has been defined by a spiritual vision centered on unity, listening and shared responsibility. “From the beginning of his papacy, Leo emphasized that we are a synodal Church working towards peace and moving forward together. Leo’s Augustinian formation will absolutely leave its imprint on what Pope Francis started. While the two have distinct personalities and styles, there is a fundamental continuity with Francis that Leo has signaled. Leo stresses that at the core of the Church is a deeper desire for a spirituality of ‘we’—a Church rooted in deep listening and bold speaking. This is where the Augustinian charism makes itself known. “This unity does not erase differences. Instead, it asks, ‘How do we create friendships that are strong enough to bear the tensions of our differences?’ In a world shaped by ‘us versus them,’ Leo insists on recognizing Christ in the completely different ‘other.’ “Finally, his leadership style is marked by discernment. Listening is so critical to him, and any caution he displays is not out of fear but wanting to listen before speaking. In a noisy world, he insists that we just need silence—trusting that through shared listening, the Church can move forward together.” Luca Cottini, PhD Professor of Italian Studies For Dr. Cottini, Pope Leo’s first year has been marked by a clear effort to position the Church in active dialogue with the modern world—especially in response to emerging global challenges, migration and an increasingly interconnected faith community. He draws parallels to the priorities of Leo XIV’s namesake, Pope Leo XIII. “Catholic social doctrine is a doctrine that the Church established to address subjects that are not directly written about in the Gospel. This doctrine was important for Pope Leo XIII and is increasingly important for Leo XIV as well. ‘Leo’ is a name that relates back to Catholic social doctrine and the need to read the changing signs of the times. By choosing the name ‘Leo,’ the Pope signaled his desire to respond to contemporary issues. “Leo XIV has also harkened back to Leo XIII in his first year by viewing migration and immigration not as a plight, but rather as an opportunity to enter into contact with new worlds. This approach connects to Leo XIV’s own background and perspective, which includes both proximity to and distance from the United States, giving him both an outsider and insider perspective as well as a critical thinking lens on these issues. “Lastly, Leo XIV has used his first year to elevate this idea of a universal Church that is much needed, shaped by his global exposure and an ability to see the world through the lens of others. He sees that we can dialogue with the world, approaching modernity not as an enemy but as something to engage with.” Patrick McKinley Brennan, JD John F. Scarpa Chair in Catholic Legal Studies According to Professor Brennan, “One of the issues that is on the Pope’s radar and has been from before the conclave is the question of the traditional Latin Mass,” a cause championed by various cardinals, bishops, priests and lay faithful around the globe. As he shares, it is a matter of great interest to a small but growing number of Catholics who recall Pope Benedict XVI’s statement that the traditional Mass—the Mass as it was celebrated by most Catholics since 1570—was “never juridically abrogated” following the Second Vatican Council. “Pope John Paul II in the 1980s, and then Pope Benedict XVI in 2007, liberalized access around the world to the traditional Mass. But Pope Francis revoked most of those permissions, citing ‘facts’ that have subsequently been called into question by investigative journalists and others. Pope Francis issued a document called Traditionis custodes, which [went against] the permissions that Benedict XVI gave in a document called Summorum pontificum in July 2007. “Now, the leadership of the Society of St. Pius X [an anti-modernist priestly fraternity] have announced that they’re going to ordain new bishops, the exact thing that got some of their predecessors excommunicated in 1988, so that the traditional Mass can continue to be celebrated and other sacraments can continue to be provided to Catholics according to the traditional rites. Reading between the lines, I think the Society of St. Pius X is trying to force Pope Leo’s hand on the Latin Mass. He’s been biding his time, working out how to respond to this hard question, and I think they’ve just decided that it’s an all-or-nothing situation. “It’s an example of how Pope Leo inherited some big problems, and I think most of the cardinals who elected him thought that they had chosen someone who, because he can listen and is committed to unity, will try his very best to find a solution that remains faithful to Catholic doctrine while bringing in as many voices as possible. Ironically, Pope Francis reduced legitimate diversity in Catholic liturgy, and while Pope Leo has a chance to restore that diversity, he has to do so in a way that addresses the irregular situation of the Society of St. Pius X.” Ilia Delio, OSF, PhD Josephine C. Connelly Endowed Chair in Christian Theology Looking ahead, Sister Delio says one of the most significant social developments Pope Leo must face is the rise of advanced technologies—in particular, increasingly sophisticated artificial intelligence models. “Our theological anthropology needs a bit of updating, as it does not currently meet the needs of our very complex world today. There are a lot of discussions on artificial intelligence and advanced technology, but the problem is that these technologies are already here and rapidly advancing. “So, we have to face this reality, not by asking ‘What is happening to us?’ but ‘What are we becoming with our technologies?’ and ‘How best can we remain human in an AI world?’ I think Pope Leo is asking similar questions, considering what makes the human person the image of God, what makes us distinct and whether there are human values that cannot be downloaded or reproduced in a digital medium. “At the same time, we must ask: Can technology deepen the human spirit by enabling a new level of collective life? Can AI technology empower the Body of Christ?” To speak with any of these faculty experts, please contact mediaexperts@villanova.edu.

Expert Insight: Netflix’s AI Bet Signals a Shift From Creation to Control in Filmmaking

Recently published articles in NPR and outlets like Rest of World explore how Netflix is accelerating its use of artificial intelligence in film production through its work with InterPositive, an artificial intelligence company built by Hollywood actor Ben Affleck, signaling a shift that is less about replacing filmmakers and more about reshaping how films are made. The deal between InterPositive and Netflix comes just over a week since the streamer pulled out of its plan to acquire Warner Brothers Discovery. Paramount agreed to acquire the media giant in a deal valued at around $110 billion. On Feb. 26, the Warner Brothers Discovery board declared Paramount's bid to be "superior" to an $83 billion deal it had previously struck with Netflix. Kimberly A. Owczarski, an associate professor at Texas Christian University who studies media franchises, told NPR in an email that Netflix's decision to partner with a filmmaker of Affleck's prominence sends out a positive message to an industry reeling from the threats posed by the growing adoption of AI across the entertainment landscape. "His status in the industry as a star, filmmaker, and producer gives substantial weight as he promotes a responsible use of AI in filmmaking," Owczarski said. March 02 - NPR The technology focuses on post-production efficiencies, using AI trained on a project’s own footage to handle tasks like relighting, continuity fixes, and visual effects, dramatically reducing time and cost while keeping creative direction in human hands. But the broader implications are harder to ignore. As Kim Owczarski notes in the feature by Rest of World, “AI is not replacing creativity, but it is reshaping labor,” underscoring how these tools could redefine roles across visual effects and post-production. While studios frame AI as assistive, the growing reliance on platform-controlled technology raises critical questions about authorship, workforce disruption, and who ultimately controls the filmmaking pipeline. Kimberly Owczarski is an associate professor in the Department of Film, Television and Digital Media at Texas Christian University. Her teaching and research focus is in the areas of conglomeration, franchises, media authorship and digital distribution.

New AI tool matches students with high-impact internships

Finding the right internship can be an important step for students, but it’s not always clear which opportunities will lead to the strongest growth. To help solve that problem, University of Florida researchers have developed an AI-powered tool that helps students identify internships most likely to accelerate their technical and professional development. Unlike traditional recommendation engines, Pro-CaRE not only predicts which opportunities will lead to stronger outcomes, it also explains why each suggestion is a good fit. In testing data collected from the students, Pro-CaRE’s predictions proved highly accurate, accounting for more than 72% of the differences in learning gains among participants. While the pilot is being tested in engineering, the tool could be adopted for other disciplines. “Internships are one of the most critical parts of an engineering education, but students often struggle to know which experiences will actually help them grow,” said Jinnie Shin, assistant professor of research and evaluation methodology in the UF College of Education. “What makes Pro-CaRE unique is that it doesn’t just offer a list of options. It provides personalized recommendations backed by data and it tells students clearly why an opportunity is a good match for them.” Pro-CaRE creates matches by analyzing each student’s coursework, major, background and self-reported interest, confidence and self-efficacy in engineering skills. It then compares that profile with a carefully chosen set of similar peers to refine suggestions. The result is more precise guidance that adapts to students at different stages of their degree programs. “Students shouldn’t have to guess or hope that an internship will be worthwhile,” Shin said. “With Pro-CaRE, they can approach opportunities knowing they’re backed by evidence, whether the role is onsite, hybrid or remote and whether it’s at a startup or a Fortune 500 company.” The system is designed to work across a wide range of companies and contexts, giving students flexibility while ensuring their choices align with their personal and professional goals. Each recommendation comes with a clear “why this?” explanation, so students can make confident decisions and discuss options more effectively with advisors. Pro-CaRE was developed by a cross-disciplinary UF team combining expertise in education and engineering. Alongside Shin, the project’s co-principal investigators include Kent Crippen in the College of Education and Bruce Carroll in the Herbert Wertheim College of Engineering. The team is exploring external funding opportunities to expand the usage and test the efficacy on a larger scale. “Ultimately, our goal is to empower students to invest their time in experiences that will have the greatest impact,” Shin said. “Pro-CaRE bridges the gap between what students hope to gain and what internships can truly deliver.”

Using AI tools empowers and burdens users in online Q&A communities

Whether you’ve searched for cooking tips on Reddit, troubleshooted tech problems on community forums or asked questions on platforms like Quora, you’ve benefited from online help communities. These digital spaces rely on people across the world to contribute their knowledge for free, and have become an essential tool for solving problems and learning new skills. New research reveals that generative artificial intelligence tools like ChatGPT are creating a double-edge effect on users in these communities, simultaneously making them more helpful while potentially overwhelming them to the point of decreasing their responses. “On the positive side, AI helps users learn to write more organized and readable answers, leading to a noticeable increase in the number of responses,” explained Liangfei Qiu, Ph.D., study coauthor and PricewaterhouseCoopers Professor at the University of Florida Warrington College of Business. “However, when users rely too heavily on AI, the mental effort required to process and refine AI outputs can actually reduce participation. In other words, AI both empowers and burdens contributors: it enables more engagement and better readability, but too much reliance can slow people down.” The study examined Stack Overflow, one of the world’s largest question-and-answer coding platforms for computer programmers, to investigate the impact of generative AI on both the quality and quantity of user contributions. Qiu and his coauthor Guohou Shan of Northeastern University’s D’Amore-McKim School of Business measured the impact of AI on users’ number of answers generated per day, answer length and readability. Specifically, they found that users who used AI tools to generate their responses contributed almost 17% more answers per day compared to those who didn’t use AI. The answers generated with AI were both shorter by about 23% and easier to read. However, when people relied too heavily on AI tools, their participation decreased. Qiu and Shan noted that the additional cognitive burden associated with heavier AI usage negatively affected the impact on a user’s answer quality. For online help communities grappling with AI policies, this research provides valuable insight into how these policies can be updated in the current AI environment. While some communities, like Stack Overflow, have banned AI tools, this research suggests that a more nuanced approach could be a better solution. Instead of banning AI entirely, the researchers suggest striking a balance between allowing AI usage while promoting responsible and moderated use. This approach, they argue, would enable users to benefit from efficiency and learning opportunities, while not compromising quality content and user cognition. “For platform leaders, the takeaway is clear: AI can boost participation if thoughtfully integrated, but its cognitive demands must be managed to sustain long-term user contributions,” Qiu said.

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.”

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.
