If the first few frames are any indicator of a blockbuster movie, hold the 2035 Best Picture Oscar for the Vera C. Rubin Observatory and its ambitious new 10-year project. On June 23, 2025, scientists at the state-of-the-art facility in the mountains of north-central Chile gave the public its first glimpses into the capabilities of its 8.4-meter Simonyi Survey Telescope, equipped with the world’s largest digital camera—a 3.2 megapixel, 6,600-pound behemoth that can photograph the whole southern sky every few nights. Its task is a decade-long lapse record-called the Legacy Survey of Space and Time (LSST). The first shots on that journey have left both the general public and astronomical community in awe, revealing in rich detail a mind-boggling number of galaxies, stars, asteroids and other celestial bodies. “The amount of sky it covers, even in just one image, is unprecedented,” said David Chuss, PhD, chair of the Department of Physics, who viewed the first images with colleagues at an organized watch party. “It’s such high-precision, beautiful detail,” added Kelly Hambleton Prša, PhD, associate professor of Astrophysics and Planetary Sciences. “It’s just mind-blowing.” What Makes Rubin and LSST So Unique? Simply, this revolutionary instrument, embarking on an equally revolutionary initiative, will observe half the sky to a greater depth and clarity than any instrument ever has before. Consider this: "The Cosmic Treasure Chest" image released by Rubin contains 1,185 individual exposures, taken over seven nights. Each one of those individual exposures covers 10 square degrees of night sky, which is about the same as looking up at 45 full moons positioned around one another. It may seem like a small size, but click the image yourself, and zoom in and out. The amount of sky captured in that range—enough to show roughly 10 million galaxies—is astounding. Per the Observatory, “it is the only astronomical tool in existence that can assemble an image this wide and deep so quickly.” “At the end of 10 years, Rubin will have observed 20 billion galaxies, and each night in that time frame it will generate 20 terabytes of data,” Dr. Hambleton Prša said. “And, because Rubin has so many different filters, we get to see the same objects in so many different ways.” According to Dr. Hambleton Prša and Dr. Chuss, the power and precision of the Rubin LSST, combined with the shear area of the sky that will be observed, will allow for an incredibly in-depth study of myriad objects, processes and events in ways nobody has ever studied them before. “For example, in our galaxy, we expect to observe only two supernovae per century,” Dr. Hambleton Prša said. “But we're observing 20 billion galaxies. For someone studying this phenomenon, the number of supernovae that they’re going to observe will be off the charts. It is an exquisite survey.” It will also provide insight into the universe’s oldest and most puzzling enigmas. “Rubin is able to look back into our universe at times when it was much smaller during its expansion and really address some of these incredible mysteries out there, like dark energy,” Dr. Chuss said. “We know the universe is expanding and that this expansion is accelerating. Rubin will trace the history of that acceleration and, from that, provide insight into the physics of the mysterious dark energy that appears to be driving it.” To enhance the technological capabilities of its instrument, scientists were invited to contribute towards the selection of the observing strategy of the telescope. The Rubin team took into consideration continual input from the astrophysics community, separated into what they call “science collaborations.” To achieve this, the Rubin team generated proposed simulations for collecting observations, which the science collaborations then assessed for their specific science goals. “The Rubin team then iterated with the science collaborations, taking into account feedback, to ultimately obtain the best strategy for the largest number of science cases,” Dr. Hambleton Prša said. Dr. Hambleton Prša is the primary contact for the Pulsating Star Subgroup, which is part of the Transients and Variable Stars Science Collaboration, the science collaboration that focuses on objects in the sky that change with time. She was the lead author among 70 co-authors on the roadmap for this science collaboration, underscoring the significant scale of community participation for each of these areas. Joined Under One Sky Dr. Hambleton Prša, Dr. Chuss and other members of the Astrophysics and Planetary Sciences Department and Department of Physics at Villanova have a vested interest in Rubin and the LSST project. In April, the two departments joined forces to launch The Villanova One Sky Center for Astrophysics, co-directed by the two faculty members. With goals to elevate the University's longstanding record of research eminence in astronomy and astrophysics and create opportunities for more students to access the disciplines, the Center partnered with the Rubin Observatory to help realize the mission. Both Villanova and Rubin share a similar vision on expanding access to this broad field of study. Fortuitously, the launch of The Villanova One Sky Center coincided with the initial data released from Rubin. What will result, Dr. Chuss says, will be a “truly awesome impact on both our Center and institution.” Dr. Hambleton Prša will advance her own research of pulsating stars, and Andrej Prša, PhD, professor of Astrophysics and Planetary Science and the primary contact for the Binary Star Subgroup, will broaden his study of short-period binary stars. Joey Neilsen, PhD, associate professor of Physics, will expand his research in black hole astrophysics. Becka Phillipson, PhD, an assistant professor of Physics, who recently led a proposal for Villanova to join the Rubin LSST Discovery Alliance, aims to increase the scope of her study of chaotic variability of compact objects. Dr. Chuss, who generally works on infrared and microwave polarimetry, which is “outside the wavelength ranges of Rubin” is interested in its complementarity with other observations, such as those of the cosmic microwave background—the oldest light in the universe—and the evolution of the large-scale structure of the universe. Subjects, he says, which are “exactly in the wheelhouse for Rubin.” Other faculty members are interested in topics such as how Rubin’s observations may change the knowledge of both the history and structure of our solar system and the population of Milky Way satellite galaxies. That is not to mention, Dr. Hambleton Prša points out, the daily 20 terabytes of data that will become available for students and postdoctoral researchers under their tutelage, who will be heavily involved in its analysis for their own projects and ideas. “This partnership is going to greatly increase our opportunities and elevate our profile,” Dr. Chuss said. “It will make our program even more attractive for faculty, postdocs and students to come and to share their knowledge and expertise. “Together, we will all have access to an incredible movie of this epoch of our universe, and the knowledge and surprises that come with it along the way.”
ChristianaCare and Children’s Hospital of Philadelphia (CHOP) today announce a new strategic affiliation to expand access to world-class pediatric care in Delaware and surrounding communities. The collaboration, which is expected to begin in spring 2026, will enhance access to specialized pediatric care by bringing CHOP’s renowned expertise closer to home for families in the communities ChristianaCare serves in Delaware, Maryland, Pennsylvania and New Jersey. By integrating CHOP’s services with ChristianaCare’s established network, the collaboration will improve care delivery, making advanced pediatric treatments more accessible and reducing the need for families to travel long distances for care. A Bold Step Forward in Pediatric Care “This collaboration brings together two amazing organizations that are already nationally recognized for clinical excellence—and we’re going to be even better together,” said Janice E. Nevin, M.D., MPH, president and CEO of ChristianaCare. “Our affiliation with CHOP marks a bold step forward in our mission to provide the highest quality care to children and families across the communities we serve. These are uncertain times for many parents with young children in need of routine or complex medical care. ChristianaCare and CHOP are joining forces to provide world-class care, close to home, at a time when it’s needed most.” “Bringing seamless, family-centered care to our patients is a priority at Children’s Hospital of Philadelphia,” said Madeline Bell, CEO at Children’s Hospital of Philadelphia. “As one of the region’s most dynamic health systems, ChristianaCare has earned a national reputation for its bold approaches to both clinical care and innovation. Our new affiliation is driven by a shared vision: redefining what is possible in health care and ensuring that every patient — at every stage of life — receives the highest standards of care, from infancy through adulthood.” “Our team at ChristianaCare is excited to work closely with Children’s Hospital of Philadelphia to bring even more specialized care to our community,” said Megan Mickley, M.D., chair of Pediatrics at ChristianaCare. “CHOP’s leadership in pediatric medicine will complement the outstanding care already provided at ChristianaCare, ensuring that our youngest patients receive the most advanced treatments in a compassionate and supportive environment.” Initial Focus and Future Growth This affiliation between ChristianaCare and CHOP represents a significant increase in access to world-class pediatric care for communities in Delaware, Maryland, southeast Pennsylvania and southern New Jersey. CHOP, a global leader in pediatric care and research for over 165 years, is consistently ranked among the top children’s hospitals in the country, known for pioneering breakthroughs across a breadth of pediatric care areas. The affiliation will include all ChristianaCare hospitals and locations where pediatric emergency and inpatients are cared for. The collaboration will initially focus on pediatric and neonatal services. Patients at ChristianaCare will have access to CHOP’s expertise in rare and complex diseases and a wide range of newborn and pediatric services, including surgery, cardiology, neurology, radiology, ophthalmology and genetics, as well as educational and research opportunities. As the collaboration grows, it will explore further opportunities to expand pediatric care and improve health care delivery in the region.
Dry eye disease is a common condition affecting one-third of the adult population and one-in-five children Professor James Wolffsohn researched the most effective blinking exercises to reduce discomfort, involving a close-squeeze-blink cycle He developed the MyDryEye app in collaboration with Alec Kingsnorth and Mark Nattriss to help sufferers An Aston University optometrist, Professor James Wolffsohn, has determined an optimum blinking exercise routine for people suffering with dry eye disease, and has developed a new app, MyDryEye, to help them complete the routine to ease their symptoms. Dry eye disease is a common condition which affects one-third of the adult population and one-in-five children, in which the eyes either do not make enough tears, or produce only poor-quality tears. It causes the eyes to become uncomfortable, with gritty- or itchy-feeling eyes, watery eyes and short-term blurred vision. It is more common in older adults and can be exacerbated by factors including dry air caused by air conditioning, dust, windy conditions, screen use and incomplete blinks, where the eye does not fully close. Professor Wolffsohn is head of Aston University’s School of Optometry and a specialist in dry eye disease. While it has long been known that blinking exercises can ease the symptoms of dry eye disease, the optimum technique, number of repetitions and necessary repeats per day are unclear. Professor Wolffsohn set out to determine the best exercises. His team found that the best technique for a dry eye blinking exercise is a close-squeeze-blink cycle, repeated 15 times, three times per day. Participants found that while they were doing their exercises symptom severity and frequency decreased, and the number of incomplete blinks decreased. Within two weeks of stopping the exercises, their symptoms returned to normal levels, showing the efficacy of the exercises. To carry out the work, Professor Wolffsohn’s team ran two studies. For the first, they recruited 98 participants, who were assessed for dry eye symptoms before and after the two weeks of blinking exercises. Participants were randomly allocated different blinking exercises to determine the most effective. A second study with 28 people measured the efficacy of the blinking exercise. Once the optimum blinking routine had been developed, Professor Wolffsohn worked withAlec Kingsnorth, an engineer and former Aston undergraduate and PhD student, and Mark Nattriss, business manager of his spin-out company, Wolffsohn Research Ltd, to develop the app, MyDryEye, which is freely available on Android and iOS operating systems. The app allows users to monitor their dry eye symptoms, assess their risk factors, add treatment reminders and monitor their compliance, complete the science-based blink exercises and find a specialist near them. Professor Wolffsohn says that the blinking exercises should be carried out as part of a treatment programme which could also include the use of lipid-based artificial tears, omega-3 supplements and warm compresses. Professor Wolffsohn said: “This research confirmed that blink exercises can be a way of overcoming the bad habit of only partially closing our eyes during a blink, that we develop when using digital devices. The research demonstrated that the most effective way to do the exercises is three times a day, 15 repeats of close, squeeze shut and reopen – just three minutes in total out of your busy lifestyle. To make it easier, we have made our MyDryEye app freely available on iOS and Android so you can choose when you want to be reminded to do the exercises and for this to map your progress and how it affects your symptoms.” Read the full paper, ‘Optimisation of Blinking Exercises for Dry Eye Disease’, in Contact Lens and Anterior Eye at https://doi.org/10.1016/j.clae.2025.102453.
Historical Significance of the Papal Name
In the wake of the historic election of Pope Leo XIV, the first American to ascend to the papacy, scholars and observers alike are reflecting on the global, historical and theological implications of his early statements and symbolic choices. His decision to take the name Leo – a name not used for over a century – immediately evokes comparisons to both Leo XIII and Leo I (Leo the Great), popes known for their firm leadership and dynamic engagement with the world. Baylor University’s Elisabeth Rain Kincaid, J.D., Ph.D., director of the Institute for Faith and Learning and an expert on early modern theology and Catholic Social Thought, said choosing the name Leo is significant, especially in today’s world. Through his choice of name, rhetorical style and theological references, the new pope is signaling a clear vision for a Church that is simultaneously grounded in tradition and open to global dialogue, Kincaid said. Kincaid is currently at work on a monograph – “Business Ethics for a Flourishing Life: Catholic Social Thought in the Modern Workplace” – in which she argues for the continued importance of Leo XIII’s thought for modern life. If you're covering the news about Pope Leo XIV and are looking to know why Cardinal Robert Prevost chose that name - we can help. Elisabeth Rain Kincaid is an author, speaker, teacher, and theologian. She has published broadly in peer-reviewed journals and popular publications. She is a frequent speaker at conferences, churches, and professional events on topics including business ethics, virtue and character, Christian engagement with law and politics, and work and vocation. She is currently the Director for the Institute for Faith and Learning at Baylor University. In her teaching, she draws upon her years of experience as a white-collar criminal defense attorney and a private equity professional, along with her ministry experience. Elisabeth is available to speak with media about this topic - simply contact Shelby Cefaratti-Bertin, M.A., Assistant Director of Media and Public Relations at Baylor University, Shelby_Cefaratti@baylor.edu or 254-327-8012 to arrange an interview today.
Taking ACT-ion for Quality Improvement
“Learning is a journey. It is continuous,” said nurse Hellen Okoth, MSN, CCRN, RN-BC, of the Transitional Surgical Unit. She was one of the learners on that journey through ChristianaCare’s professional development program Achieving Competency Today (ACT). ACT, a 12-week graduate-level program dedicated to health care improvement, will celebrate its 40th session in 2025. Some 1,000 caregivers have graduated from ACT and have tested some 140 innovative project ideas since the program’s launch in 2003. On April 9, three ACT teams presented their quality improvement projects at the John H. Ammon Medical Education Center on ChristianaCare’s Newark campus. Interdisciplinary, experiential learning programs like ACT create a rich and dynamic learning environment,” said Tabassum Salam, M.D., MBA, FACP, chief learning officer for ChristianaCare. “The emphasis on continuous improvement and real-world applications of the educational content sets our ACT graduates up for lifelong learning and repeated application of these new skills.” The ACT course is a collaborative experience that brings together learners from diverse disciplines to tackle real-world health care challenges. Participants learn from health system leaders and gain a broad perspective on health care through coursework. They work in teams to complete problem-solving projects from start to finish using the Plan-Do-Check-Act (PCDA) model of continuous improvement. Facilitators, who are experts in improvement science and team effectiveness, guide the teams through the process, ensuring that each project is meticulously planned and executed. ChristianaCare offers many professional development opportunities. Click here for careers and benefits. “The hands-on projects in ACT enable learners to innovate and test out solutions in settings that directly benefit patients, leading to better outcomes and a higher quality of care,” Salam said. The three most recent teams presented improvement research that has the potential to expand beyond their pilot stage to other areas of the health system. ‘Hush! For the Love of Health’ In “Hush! For the Love of Health,” an interdisciplinary team worked to reduce noise levels on the Cardiovascular Critical Care Unit (CVCCC) at Christiana Hospital. Their goal was to decrease ambient noise levels by 10 decibels during the study period. Intensive care units often experience noise levels that can exceed 80 decibels. A quiet environment is 30 to 40 decibels. Members of the “Hush” project found creative ways to reduce noise on an intensive care unit. Ambient noise refers to all sounds present in the background, which research shows can interfere with communication, concentration and comfort. In a hospital setting, these sounds may include alarms, conversations, announcement and pages and carts moving by. The team looked for opportunities to safely reduce the number of alarms sounding. By collaborating with Philips technology company to lower alarm volumes and eliminate redundant alarms, they reduced the number of alarms sounding from 10,000 to 3,000 daily and successfully decreased noise levels by 13 decibels, exceeding their goal. “It’s good for patients to have a quiet environment and it fights alarm fatigue for caregivers,” said Dylan Norris, a pre-medical student from the University of Delaware and participant in the ACT course. ‘Show Up and Show Out’ Reducing the no-show rate among patients in primary care practices improves health outcomes and conserves resources. In “Show Up and Show Out: Boosting Patient Attendance in Primary Care,” the project team aimed to reduce the incidence of no-show appointments at the Wilmington Adult Medicine (WAM) practice by 10%. The “Show Up and Show Out” project team used personalized communication outreach to patients to encourage keeping their primary care appointments. “Our literature review showed that personal relationships with providers are one thing that can encourage people to attend appointments,” said team member Christi Karawan, MS, BSN, CCRN-CSC. The key to their problem-solving strategy was using a secure messaging platform for automatic appointment reminders specifically for WAM that were personalized with the provider’s name and thanking the patients for letting WAM be a part of their healthcare team. Other steps on the road to success were signage around the practice encouraging patients to update their contact information and calls from office assistants and medical assistants to unconfirmed patients the day prior to their appointments. The team achieved a 9.5% reduction in no-shows, just shy of their goal, over a two-week period. An office assistant who participated in the pilot said, “Outreach has been helpful not only in getting people in but in getting people to reschedule or cancel. We can catch it before it becomes a no-show.” ‘Magnetic Efficiency’ To address delays in patient transport from MRI testing at Newark campus, an ACT team created a new communication workflow to directly connect patient escort dispatch to the MRI charge technician. The ACT team aimed to decrease patient wait times following MRI completion for stretcher transport back to patients rooms by 25% — and “a bold goal,” said one colleague — during the study period. The “Magnetic Efficiency” team identified a new workflow to get patients back to their hospital rooms faster after MRI testing. Using Vocera wearable communications tools, the team created a thread for direct communication between Escort Dispatch caregivers and MRI charge technicians. Also, when an Escort transporter dropped off a patient for an MRI, the transporter asked MRI staff if any patients were ready to go back to their rooms. These changes in communication and empowerment consolidated transports and led to a 17% reduction in wait time during the two-week pilot. “We don’t want people to work harder,” said team member Tim Kane, BSN, RN. “We wanted to avoid preventable delays.” Both teams expressed satisfaction and improved communication with the new process and they expressed interest in continuing the process after the pilot ended. Future forward The ACT course has a rich history, originating from a specific initiative piloted by the Robert Wood Johnson Foundation with ChristianaCare among the early adopters along with Harvard University, the University of Pennsylvania, Johns Hopkins University and Beth Israel Deaconess Medical Center. Through the years, ChristianaCare ACT team members have seen their projects live on both as permanent changes throughout the health system and, more personally, in their professional growth. “I was able to enhance my creativity, organizational and problem-solving skills,” said Starr Lumpkin, a staff assistant who was on the “Hush” team. “This was a pivotal journey for me.” ChristianaCare is growing its program to develop a pipeline for the next generation of health professionals, said Safety and Quality Education Specialist Claire Rudolph, MSM, CPHQ. “We have a varied group of learners and facilitators who are making an impact on health care quality, cost and safety.” Dylan Norris was the first participant from a new partnership with the University of Delaware for pre-med students to get quality improvement experience. “I have learned so much about what goes into a quality improvement project. Buy-in from the stakeholders is key in implementing any new project successfully,” she said. “I have also learned about the importance of the initial research that goes into creating a new project and how much pre-planning goes into it.” Closing the event, Clinical Effectiveness Officer Christian Coletti, M.D., MHCDS, FACEP, FACP, called on the ACT graduates to use their newfound “superpowers” — “vision, seeing the future, catching something before it breaks. “It’s not a glitch in the matrix,” he said. “You are the most important people at the bedside – hearing the alarms going off or the stretchers piling up. Work to identify problems and move toward solutions in your own microenvironments. Pass on your powers with reckless abandon.”

Virtual reality training tool helps nurses learn patient-centered care
University of Delaware computer science students have developed a digital interface as a two-way system that can help nurse trainees build their communication skills and learn to provide patient-centered care across a variety of situations. This virtual reality training tool would enable users to rehearse their bedside manner with expectant mothers before ever encountering a pregnant patient in person. The digital platform was created by students in Assistant Professor Leila Barmaki’s Human-Computer Interaction Laboratory, including senior Rana Tuncer, a computer science major, and sophomore Gael Lucero-Palacios. Lucero-Palacios said the training helps aspiring nurses practice more difficult and sensitive conversations they might have with patients. "Our tool is targeted to midwifery patients,” Lucero-Palacios said. “Learners can practice these conversations in a safe environment. It’s multilingual, too. We currently offer English or Turkish, and we’re working on a Spanish demo.” This type of judgement-free rehearsal environment has the potential to remove language barriers to care, with the ability to change the language capabilities of an avatar. For instance, the idea is that on one interface the “practitioner” could speak in one language, but it would be heard on the other interface in the patient’s native language. The patient avatar also can be customized to resemble different health stages and populations to provide learners a varied experience. Last December, Tuncer took the project on the road, piloting the virtual reality training program for faculty members in the Department of Midwifery at Ankara University in Ankara, Turkey. With technical support provided by Lucero-Palacios back in the United States, she was able to run a demo with the Ankara team, showcasing the UD-developed system’s interactive rehearsal environment’s capabilities. Last winter, University of Delaware senior Rana Tuncer (left), a computer science major, piloted the virtual reality training program for Neslihan Yilmaz Sezer (right), associate professor in the Department of Midwifery, Ankara University in Ankara, Turkey. Meanwhile, for Tuncer, Lucero-Palacios and the other students involved in the Human-Computer Interaction Laboratory, developing the VR training tool offered the opportunity to enhance their computer science, data science and artificial intelligence skills outside the classroom. “There were lots of interesting hurdles to overcome, like figuring out a lip-sync tool to match the words to the avatar’s mouth movements and figuring out server connections and how to get the languages to switch and translate properly,” Tuncer said. Lucero-Palacios was fascinated with developing text-to-speech capabilities and the ability to use technology to impact patient care. “If a nurse is well-equipped to answer difficult questions, then that helps the patient,” said Lucero-Palacios. The project is an ongoing research effort in the Barmaki lab that has involved many students. Significant developments occurred during the summer of 2024 when undergraduate researchers Tuncer and Lucero-Palacios contributed to the project through funding support from the National Science Foundation (NSF). However, work began before and continued well beyond that summer, involving many students over time. UD senior Gavin Caulfield provided foundational support to developing the program’s virtual environment and contributed to development of the text-to-speech/speech-to-text capabilities. CIS doctoral students Fahim Abrar and Behdokht Kiafar, along with Pinar Kullu, a postdoctoral fellow in the lab, used multimodal data collection and analytics to quantify the participant experience. “Interestingly, we found that participants showed more positive emotions in response to patient vulnerabilities and concerns,” said Kiafar. The work builds on previous research Barmaki, an assistant professor of computer and information sciences and resident faculty member in the Data Science Institute, completed with colleagues at New Jersey Institute of Technology and University of Central Florida in an NSF-funded project focused on empathy training for healthcare professionals using a virtual elderly patient. In the project, Barmaki employed machine learning tools to analyze a nursing trainee’s body language, gaze, verbal and nonverbal interactions to capture micro-expressions (facial expressions), and the presence or absence of empathy. “There is a huge gap in communication when it comes to caregivers working in geriatric care and maternal fetal medicine,” said Barmaki. “Both disciplines have high turnover and challenges with lack of caregiver attention to delicate situations.” UD senior Rana Tuncer (center) met with faculty members Neslihan Yilmaz Sezer (left) and Menekse Nazli Aker (right) of Ankara University in Ankara, Turkey, to educate them about the virtual reality training tool she and her student colleagues have developed to enhance patient-centered care skills for health care professionals. When these human-human interactions go wrong, for whatever reason, it can extend beyond a single patient visit. For instance, a pregnant woman who has a negative health care experience might decide not to continue routine pregnancy care. Beyond the project’s potential to improve health care professional field readiness, Barmaki was keen to note the benefits of real-world workforce development for her students. “Perceptions still exist that computer scientists work in isolation with their computers and rarely interact, but this is not true,” Barmaki said, pointing to the multi-faceted team members involved in this project. “Teamwork is very important. We have a nice culture in our lab where people feel comfortable asking their peers or more established students for help.” Barmaki also pointed to the potential application of these types of training environments, enabled by virtual reality, artificial intelligence and natural language processing, beyond health care. With the framework in place, she said, the idea could be adapted for other types of training involving human-human interaction, say in education, cybersecurity, even in emerging technology such as artificial intelligence (AI). Keeping people at the center of any design or application of this work is critical, particularly as uses for AI continue to expand. “As data scientists, we see things as spreadsheets and numbers in our work, but it’s important to remember that the data is coming from humans,” Barmaki said. While this project leverages computer vision and AI as a teaching tool for nursing assistants, Barmaki explained this type of system can also be used to train AI and to enable more responsible technologies down the road. She gave the example of using AI to study empathic interactions between humans and to recognize empathy. “This is the most important area where I’m trying to close the loop, in terms of responsible AI or more empathy-enabled AI,” Barmaki said. “There is a whole area of research exploring ways to make AI more natural, but we can’t work in a vacuum; we must consider the human interactions to design a good AI system.” Asked whether she has concerns about the future of artificial intelligence, Barmaki was positive. “I believe AI holds great promise for the future, and, right now, its benefits outweigh the risks,” she said.
NASA Grant Funds Research Exploring Methods of Training Vision-Based Autonomous Systems
Conducting research at 5:30 a.m. may not be everybody’s first choice. But for Siddhartha Bhattacharyya and Ph.D. students Mohammed Abdul, Hafeez Khan and Parth Ganeriwala, it’s an essential part of the process for their latest endeavor. Bhattacharyya and his students are developing a more efficient framework for creating and evaluating image-based machine learning classification models for autonomous systems, such as those guiding cars and aircraft. That process involves creating new datasets with taxiway and runway images for vision-based autonomous aircraft. Just as humans need textbooks to fuel their learning, some machines are taught using thousands of photographs and images of the environment where their autonomous pupil will eventually operate. To help ensure their trained models can identify the correct course to take in a hyper-specific environment – with indicators such as centerline markings and side stripes on a runway at dawn – Bhattacharyya and his Ph.D. students chose a December morning to rise with the sun, board one of Florida Tech’s Piper Archer aircraft and photograph the views from above. Bhattacharyya, an associate professor of computer science and software engineering, is exploring the boundaries of operation of efficient and effective machine-learning approaches for vision-based classification in autonomous systems. In this case, these machine learning systems are trained on video or image data collected from environments including runways, taxiways or roadways. With this kind of model, it can take more than 100,000 images to help the algorithm learn and adapt to an environment. Today’s technology demands a pronounced human effort to manually label and classify each image. This can be an overwhelming process. To combat that, Bhattacharyya was awarded funding from NASA Langley Research Center to advance existing machine learning/computer vision-based systems, such as his lab’s “Advanced Line Identification and Notation Algorithm” (ALINA), by exploring automated labeling that would enable the model to learn and classify data itself – with humans intervening only as necessary. This measure would ease the overwhelming human demand, he said. ALINA is an annotation framework that Hafeez and Parth developed under Bhattacharyya’s guidance to detect and label data for algorithms, such as taxiway line markings for autonomous aircraft. Bhattacharyya will use NASA’s funding to explore transfer learning-based approaches, led by Parth, and few-shot learning (FSL) approaches, led by Hafeez. The researchers are collecting images via GoPro of runways and taxiways at airports in Melbourne and Grant-Valkaria with help from Florida Tech’s College of Aeronautics. Bhattacharyya’s students will take the data they collect from the airports and train their models to, in theory, drive an aircraft autonomously. They are working to collect diverse images of the runways – those of different angles and weather and lighting conditions – so that the model learns to identify patterns that determine the most accurate course regardless of environment or conditions. That includes the daybreak images captured on that December flight. “We went at sunrise, where there is glare on the camera. Now we need to see if it’s able to identify the lines at night because that’s when there are lights embedded on the taxiways,” Bhattacharyya said. “We want to collect diverse datasets and see what methods work, what methods fail and what else do we need to do to build that reliable software.” Transfer learning is a machine learning technique in which a model trained to do one task can generalize information and reuse it to complete another task. For example, a model trained to drive autonomous cars could transfer its intelligence to drive autonomous aircraft. This transfer helps explore generalization of knowledge. It also improves efficiency by eliminating the need for new models that complete different but related tasks. For example, a car trained to operate autonomously in California could retain generalized knowledge when learning how to drive in Florida, despite different landscapes. “This model already knows lines and lanes, and we are going to train it on certain other types of lines hoping it generalizes and keeps the previous knowledge,” Bhattacharyya explained. “That model could do both tasks, as humans do.” FSL is a technique that teaches a model to generalize information with just a few data samples instead of the massive datasets used in transfer learning. With this type of training, a model should be able to identify an environment based on just four or five images. “That would help us reduce the time and cost of data collection as well as time spent labeling the data that we typically go through for several thousands of datasets,” Bhattacharyya said. Learning when results may or may not be reliable is a key part of this research. Bhattacharyya said identifying degradation in the autonomous system’s performance will help guide the development of online monitors that can catch errors and alert human operators to take corrective action. Ultimately, he hopes that this research can help create a future where we utilize the benefits of machine learning without fear of it failing before notifying the operator, driver or user. “That’s the end goal,” Bhattacharyya said. “It motivates me to learn how the context relates to assumptions associated with these images, that helps in understanding when the autonomous system is not confident in its decision, thus sending an alert to the user. This could apply to a future generation of autonomous systems where we don’t need to fear the unknown – when the system could fail.” Siddhartha (Sid) Bhattacharyya’s primary area of research expertise/interest is in model based engineering, formal methods, machine learning engineering, and explainable AI applied to intelligent autonomous systems, cyber security, human factors, healthcare, explainable AI, and avionics. His research lab ASSIST (Assured Safety, Security, and Intent with Systematic Tactics) focuses on the research in the design of innovative formal methods to assure performance of intelligent systems, machine learning engineering to characterize intelligent systems for safety and model based engineering to analyze system behavior.

Summary: The article explores the Fear of Running Out (FORO), a psychological phenomenon that stems from anxiety about resource scarcity, particularly in retirement. FORO is especially common among seniors who fear depleting their financial, physical, or emotional resources as they age. Unlike FOMO (Fear of Missing Out), FORO focuses on the depletion of existing assets, often leading to cautious decision-making, delayed spending, or self-sabotaging behaviours like excessive frugality or social withdrawal. While some instances of FORO are valid—such as retirees who underestimated their living expenses—others are more psychological, with financially secure individuals still feeling paralyzed by fear and unable to enjoy their retirement fully. There are practical solutions, but they require more than just emotional support. We also need to address the lack of formal retirement planning and literacy. Most retirees have insufficient knowledge about tax-efficient asset drawdowns, and the limited guidance from financial institutions exacerbates these fears. We’ve all heard of FOMO (fear of missing out)—that nagging anxiety when everyone else seems to be at a fabulous party while you’re at home scrolling through social media, eating last night’s leftovers straight from the container. As we age, the fears we carry evolve—and for some, they get a little louder, quirkier, and much more challenging to ignore. A unique set of acronyms has emerged for older adults to describe these creeping anxieties. Allow me to introduce you to the unholy trinity of aging fears: FOGO (Fear of Getting Old): This one typically kicks in around our mid-to-late 50s when the realization hits and panic sets in: "Wait... I’m not young anymore?" Have I saved enough? Have I experienced enough? Am I running out of time? Cue the classic symptoms: splurging on bright red sports cars, embarking on bucket-list trips to exotic locales, or dating someone who knows what "Netflix and chill" really means, not cozying up with a movie. And yes, sometimes while still married. It’s all part of the "midlife crisis" package—a desperate attempt to outrun Father Time. But let’s be honest: The comb-over isn’t fooling anyone. FOBO (Fear of Being Old): This stage sneaks in during your 70s, as your "best before" date blinks ominously on life’s metaphorical packaging. Many enter into a state of "defensive denial," refusing to acknowledge their age or any limitations, insisting they are still as capable as ever, even when struggling with specific tasks. In this stage, people can demonstrate "overcompensation - Desperately trying to prove they’re still youthful. Many will refuse to use mobility aids or decline assistance from family or caregivers out of pride. Others will shut down anyone who dares to suggest they are old. “Me? Old? Please. I just got a brand-new hip last year!” FORO (Fear of Running Out): Now we get to the show's real star. FORO enters the spotlight as you thoughtfully consider retirement and suddenly takes over the plot. It’s the fear of running out—of money, energy, time, or maybe even snacks at movie night. This one’s a relentless buzz in the background of every decision, from how you spend your savings to whether you should buy name-brand peanut butter or settle for the generic jar. If left unchecked, FORO can steal the joy out of today by worrying too much about tomorrow. We have all heard the stories of people passing away with millions of dollars in the bank, yet they lived in squalor, afraid to spend their money. Now, FORO can manifest in all kinds of ways. Some are almost funny in hindsight. Remember the pandemic toilet paper wars of 2020? Or that panic at a party when you’re convinced you don’t have enough food for your guests, only to find yourself drowning in leftovers? But for seniors in retirement, FORO often takes on a much more serious tone—like running out of money, energy, or health as the years go by. These thoughts can be terrifying for the aged. And sometimes, this fear is warranted. Imagine a retiree who underestimated their living expenses, burned through savings too quickly, and now faces the stark reality of financial insecurity. That’s a legitimate case of FORO that demands attention, planning, and maybe a shift in lifestyle. But other times, FORO is more like a shadow in the dark—unsettling at first glance but harmless once illuminated. For example, some seniors with reasonable pensions, savings, and even supplemental income streams might still be too paralyzed by the fear of running out to take that dream vacation or help their grandchildren with school. In this situation, it is doubtful that there will ever be enough. This type of FORO can cause harm through neglect. This unfounded FORO can keep people from genuinely thriving during their golden years. There are well-documented cases of individuals who have perished from thirst in the desert while carrying full bottles of water. They were too frightened of running out of water to save their lives by drinking it. Most of us shake our heads and think we would never do that, but FORO represents a compelling fear that can lead to self-sabotaging behaviours. If FORO could result in death in the aforementioned desert scenario, how might it influence decisions regarding our significant assets, such as our homes? Unfortunately, many retirees pinch pennies and go without while living in homes with considerable equity, refusing to access it for fear of running out (FORO). So, how do we know when FORO is a valid warning signal and when it’s just a psychological hurdle? And, more importantly, how can we tackle this fear to ensure it doesn’t stand in the way of living a joyful, fulfilled retirement? Read on; we’ll dive deeper into the concept of FORO—why it exists, how it can sneak into our decision-making, and, most importantly, actionable strategies to manage it. Remember, your golden years shouldn’t be ruled by fear—they should be a time to shine. The Fear of Running Out (FORO) is a psychological concept rooted in anxiety about scarcity or insufficiency, particularly concerning essential resources like money, time, or opportunities. It's akin to FOMO (Fear of Missing Out), but instead emphasizes the anxiety of depleting one's existing resources rather than worrying about missed experiences. While FORO has not been as widely studied as FOMO in academic circles, the term has gained traction in financial and psychological contexts, particularly regarding retirement planning, economic behaviour, and decision-making. Although it’s unclear who explicitly popularized the term “Fear of Running Out,” it has become a recurring theme in financial planning discussions and among behavioural psychologists studying how individuals manage uncertainty and risk. The Psychology of FORO FORO is deeply rooted in psychological concepts of scarcity and loss aversion, both key ideas in behavioural economics. Loss aversion, central to Daniel Kahneman and Amos Tversky’s prospect theory, highlights that the pain of losing something outweighs the joy of gaining an equivalent amount. In the context of retirement, the fear of running out of money reflects this principle—financial depletion carries the weight of losing essential aspects like security, independence, and quality of life, making it feel particularly distressing. The work of researchers like Eldar Shafir and Senthil Mullainathan on the scarcity mindset further illuminates this phenomenon. They suggest that when people are preoccupied with avoiding resource depletion, they often develop tunnel vision, focusing narrowly on the immediate issue. For seniors worried about outliving their savings, this can manifest as excessive caution or hesitation in deciding to spend or draw down resources, even when such concerns may not be warranted. Faced with this dilemma, some seniors develop inertia, choose to do nothing, and ignore the situation altogether. According to a 2024 report by the Ontario Securities Commission, 13% of pre-retirees and 19% of retirees among Canadians aged 50 and older have a formal written retirement plan, which is a significant cause for concern. This reflects a widespread lack of structured financial and retirement literacy. Without a clear strategy, many individuals may not fully understand how to manage their resources effectively throughout retirement, particularly when it comes to de-accumulating (spending) assets in a tax-efficient manner. We can quickly start to see why many older Canadians have FORO. One key issue is that minimal accessible information exists on strategies for drawing down retirement savings to minimize taxes while ensuring long-term financial security. For example, the timing and order in which individuals withdraw from registered accounts like RRSPs, TFSAs, non-registered investments, or access their home equity can dramatically impact their overall tax burden and available income in retirement. Unfortunately, this type of guidance is often overlooked in financial planning resources, leaving most retirees guessing how much money is enough. The financial industry also contributes to this gap. Banks and many financial advisors are primarily compensated through commissions tied to the sale and management of investments, such as mutual funds or other financial products. This model does not incentivize them to provide comprehensive advice on strategically spending down savings. As a result, many seniors are left without the critical guidance they need to navigate the complexities of de-accumulation, leading to suboptimal emotionally driven decisions and increased financial stress. This lack of tailored advice is particularly problematic for Canadians who rely on paying off their homes as their primary financial plan. While homeownership is a valuable asset, it is not liquid, and converting it into usable retirement income can be challenging without proper planning. The fear of running out of money (FORO) becomes especially acute for these individuals, as they may not have the financial and retirement literacy or tools to make informed decisions about how to fund their retirement, especially concerning using home equity. In short, the low prevalence of formal retirement plans, insufficient education on tax-efficient de-accumulation, and the misaligned incentives of financial institutions significantly disadvantage seniors. This gap exacerbates financial insecurity and leaves many retirees vulnerable to the psychological and practical challenges of FORO, particularly those who rely on home equity, an illiquid asset, as their primary financial safety net. Addressing these issues requires a broader emphasis on financial and retirement literacy and unbiased, accessible advice tailored to retirees' unique needs. Key Components of FORO: 1. Scarcity Mindset—Seniors facing FORO might develop a scarcity mindset, which can lead to overly frugal behaviours. For example, they may reduce spending on essential support services or forego social activities to protect their savings, even when financially secure. 2. Emotional Triggers—FORO is tied to deeper emotional needs like safety, independence, and legacy. At its core is the fear that people will have nowhere to live, won’t have enough money to care for themselves, and will not have any money left to leave a legacy. 3. Decision Paralysis - FORO can cause retirees to delay allocating resources, from downsizing a home to sourcing pension-type income. This indecision can lead to missed opportunities or unnecessary sacrifices. 4. Overcompensation—In some cases, the fear of running out can lead to self-sabotage behaviours like hoarding money or withdrawing from social activities. These behaviours reduce quality of life and increase feelings of isolation. The Solution: A comprehensive approach that combines emotional support, practical planning, and mindset adjustments is essential to helping retirees overcome FORO. By addressing their fears and financial realities, they can gain the confidence to enjoy their retirement years without worrying about running out of money. 1. Acknowledgement and Understanding - Listen and empathize: Begin by genuinely listening to the retiree's concerns, recognizing that FORO is an emotional issue tied to deep-seated fears about security and independence. Normalize the fear: Reassure them that the fear of running out of money is common, especially in retirement. Explain the reasons behind this fear: Retirees often can’t return to work to supplement income. Lifespans and healthcare costs are unpredictable, creating uncertainty. The transition from accumulating wealth to spending it feels unnatural to many. 2. Develop a Retirement Spending Plan—Create a tailored plan. Outline a sustainable spending strategy aligning with the client's lifestyle, goals, and resources: Leverage expertise: Collaborate with their bank manager or financial advisor to develop a realistic budget covering essential and discretionary expenses. Focus on balance: Establish a balance between meeting current needs and maintaining future security. 3. Generate Pension-Like Income - Explore income solutions: Help them research ways to create predictable income streams, such as: Purchasing an annuity to convert part of their savings or equity into guaranteed income. Consider equity mortgage products for additional cash flow if they have sufficient home equity. Address misconceptions: Explain how these tools can reduce uncertainty and provide peace of mind. 4. Emergency Fund - Health care may be needed later in life and can be costly. Setting money aside for unexpected expenses will offer great comfort and peace of mind. 5. Mindset Shifts - Reframe perspectives: Encourage retirees to focus on the opportunities their resources provide rather than fixating on worst-case scenarios: Promote enjoyment: Remind them that retirement is a time to enjoy the fruits of their labour, not live in constant fear. Highlight the importance of self-care and experiences that bring joy and fulfillment. 6. Legacy Planning - Address legacy concerns: Help them create an estate plan or designate resources for loved ones and causes they care about, ensuring their wishes are honoured: Provide clarity: Show how planning for a legacy can reduce anxiety about leaving something behind while meeting their current needs. The Fear of Running Out is more than just a financial concern—it’s a deeply emotional and psychological issue for seniors facing the unpredictability of retirement. By addressing this fear in practical and empathetic ways, we can give retirees the tools and confidence to enjoy their golden years without worrying about depletion or feeling like they need to stockpile financial "water bottles" for a drought that may never come. And there you have it—FORO might be a formidable guest at the retirement table, but it doesn’t have to steal the show. By addressing the emotional roots of this fear, creating practical plans, and shifting the focus to what’s possible, retirees can turn their golden years into precisely that: golden. Remember, retirement isn’t about tiptoeing around scarcity; it’s about celebrating a lifetime of hard work and savouring the moments that make life rich. So, let’s leave FORO in the shadows where it belongs and step confidently into a retirement that truly shines. And let’s be honest, no one wants their legacy to read: "Lived frugally, died rich, and missed the Boat to the Caribbean." Don't retire---Re-Wire! Sue
Aston University study reveals the illusion of ‘dazzle’ paint on World War I battleships
The Zealandia in wartime dazzle paint. Image: Australian National Maritime Museum on The Commons Geometric ‘dazzle’ camouflage was used on ships in WWI to confuse enemy onlookers as to the direction and speed of the ship Timothy Meese and Samantha Strong reanalysed historic data from 1919 and found that the ‘horizon effect’ is more effective for confusion When viewing a ship at distance, it often appears to be travelling along the horizon, regardless of its actual direction of travel – this is the ‘horizon effect’. A new analysis of 105-year-old data on the effectiveness of ‘dazzle’ camouflage on battleships in World War I by Aston University researchers Professor Tim Meese and Dr Samantha Strong has found that while dazzle had some effect, the ‘horizon effect’ had far more influence when it came to confusing the enemy. During World War I, navies experimented with painting ships with ‘dazzle’ camouflage – geometric shapes and stripes – in an attempt to confuse U-boat captains as to the speed and direction of travel of the ships and make them harder to attack. The separate ‘horizon effect’ is when a person looks at a ship in the distance, and it appears to be travelling along the horizon, regardless of its actual direction of travel. Ships travelling at an angle of up to 25° relative to the horizon appear to be travelling directly along it. Even with those at a greater angle to the horizon, onlookers significantly underestimate the angle. Despite widespread use of dazzle camouflage, it was not until 1919 that a proper, quantitative study was carried out, by MIT naval architecture and marine engineering student Leo Blodgett for his degree thesis. He painted model ships in dazzle patterns and placed them in a mechanical test theatre with a periscope, like those used by U-boat captains, to measure how much onlookers’ estimations of the ships’ direction of travel deviated from their actual direction of travel. Professor Meese and Dr Strong realised that while the data collected by Blodgett was useful, his methods of experimental design fell short of modern standards. He’d found that dazzle camouflage worked, but the Aston University team suspected that dazzle alone was not responsible for the results seen, cleaned the data and designed new analysis to better understand what it really shows. Dr Strong, a senior lecturer at Aston University’s School of Optometry, said: “It's necessary to have a control condition to draw firm conclusions, and Blodgett's report of his own control was too vague to be useful. We ran our own version of the experiment using photographs from his thesis and compared the results across the original dazzle camouflage versions and versions with the camouflage edited out. Our experiment worked well. Both types of ships produced the horizon effect, but the dazzle imposed an additional twist.” If the errors made by the onlookers in the perceived direction of travel of the ship were entirely due to the ‘twist’ on perspective caused by dazzle paintwork, the bow, or front, of the ship, would always be seen to twist away from its true direction. However, Professor Meese and Dr Strong instead showed that when the true direction was pointing away from the observer, the bow was often perceived to twist towards the observer instead. Their detailed analysis showed a small effect of twist from the dazzle camouflage but a much larger one from the horizon effect. Sometimes these effects were in competition, sometimes in harmony. Professor Meese, a professor of vision science at the School of Optometry, said: “We knew already about the twist and horizon effects from contemporary computer-based work with colleagues at Abertay University. The remarkable finding here is that these same two effects, in similar proportions, are clearly evident in participants familiar with the art of camouflage deception, including a lieutenant in a European navy. This adds considerable credibility to our earlier conclusions by showing that the horizon effect – which has nothing to do with dazzle – was not overcome by those best placed to know better. “This is a clear case where visual perception is more powerful than knowledge. In fact, back in the dazzle days, the horizon effect was not identified at all, and Blodgett's measurements of perceptual bias were attributed entirely to the camouflage, deceiving the deceivers.” Professor Meese and Dr Strong say that more work is required to fully understand how dazzle might have increased perceptual uncertainty of direction and speed but also the geometry behind torpedo-aiming tactics that might have supported some countermeasures.
