Weird and complex life emerged on Earth as the planet's magnetic field gave way
The Earth’s magnetic field plays a key role in making the planet habitable. It shields lifeforms from harmful solar and cosmic radiation. It helps limit erosion of the atmosphere and keeps water from escaping into space. But new data show a prolonged near collapse of Earth’s magnetic field that took place some 575-565 million years ago coincided with the blossoming of macroscopic complex animal life. We now face the possibility of a new, unexpected twist in how life might relate to the magnetic field, says John A. Tarduno, the William R. Kenan Professor of Geophysics and the dean of research at the School of Arts and Sciences and the Hajim School of Engineering and Applied Sciences at the University of Rochester. “That twist could reach deep into Earth’s inner core,” says Tarduno, who recently wrote about the findings for Physics Today magazine. Tarduno is frequently cited by news outlets, like CNN, The Washington Post, and Smithsonian magazine, on matters related to the Earth’s inner core, or dynamo, and magnetic field.

The £1.25m study, being led by the University of Derby, is trialling antiviral medications as a treatment for symptoms of long COVID Professor Ian Maidment from Aston Pharmacy School is the lead pharmacist and will provide support for the clinical trials It is estimated that more than 2m people in the UK and more than 144m globally live with long COVID Professor Ian Maidment, at Aston Pharmacy School, is the lead pharmacist on a groundbreaking research project looking to find a treatment for symptoms of long COVID, which is being led by the University of Derby. The £1.25m trial, which is the first of its kind in the UK, is exploring whether antiviral medications can be used as an effective treatment option for patients diagnosed with long COVID. It is estimated that more than 2m people in the UK and more than 144m globally live with long COVID and almost a quarter of sufferers have had their symptoms for more than two years. Symptoms are broad and include extreme fatigue and breathlessness, palpitations, and brain fog. The trial, which began in September 2024, is part of a wider programme of groundbreaking research being led by the University of Derby. Involving 72 patients, the research is trialling the use of an antiviral drug that can be given to those admitted to hospital because of a COVID-19 infection. As most people experience a community infection and are not hospitalised, they do not have a way to access this medication. By taking the drug out of the acute admission setting, the researchers are hoping to see whether it can help those living with long COVID and alleviate some of the symptoms that they are living with. During the trial, patients undergo a series of assessments at the University of Derby’s specialist facilities before attending the hospital to receive the antiviral drug intravenously for five consecutive days, delivered in collaboration with experts from University Hospitals of Derby and Burton NHS Foundation Trust. Researchers from the University of Exeter are also involved, and the study is being managed by the University of Plymouth’s Peninsula Clinical Trials Unit. Professor Maidment will provide support for the clinical trials. Patients recruited in Exeter will undertake detailed body scans, which will be analysed to check if the antiviral medication has reduced inflammation, which may occur in people with long COVID. Mark Faghy, professor in clinical exercise science at the University of Derby and the study lead, said: “The impact long COVID has on the lives of patients is huge. For many, it can be debilitating, interfering with work, family life, and socialising, and millions are suffering across the world. Yet, at present, there are no confirmed treatments for the condition. Five years on from the start of the pandemic, long COVID remains a significant health and societal challenge, which is why this project is so important. “This is an ongoing project with various phases and is still in its infancy, but we are excited to have taken the first steps to hopefully improve the quality of life for those living with long COVID.” Professor David Strain, clinical lead based at the University of Exeter Medical School, said: “There is a clear need for people living with long COVID and we hope from this study we can see a reduction in the symptoms people experience. It will be an ongoing project with various phases, but we are excited to be taking the first steps to improve patients' quality of life.” Professor Ian Maidment, Aston Pharmacy School, said: “We need clinical trials to develop new and effective treatments for long COVID. Pharmacy support is critical for the successful delivery of these studies.” Over the past four years, Professor Faghy and his team at the University of Derby have conducted a series of international studies to explore the impacts of acute and long COVID, looking to understand the causes and contributing factors of long COVID by bringing clinical insight together with the lived experience of patients.
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.
Florida Tech Welcomes Visiting Australian Scholar to Aid in Antifouling Research
Florida Tech’s Center for Corrosion and Biofouling Control is welcoming a new teammate for the semester. Tamar Jamieson, a postdoctoral researcher hailing from Australia’s Flinders University, is in Melbourne, Fla. to collaborate on biofouling research with assistant professor of marine sciences Kelli Hunsucker and professor of oceanography and ocean engineering Geoffrey Swain. Biofouling is the growth of a bacterial film or larger marine life, such as barnacles, after an object’s surface is submerged in water. It can inhibit a ship’s functionality by creating drag and slowing it down, which forces the vessel to use more fuel and emit more greenhouse gases. Over the course of the semester, Jamieson will help Hunsucker’s team develop a collaborative experiment to test antifouling techniques, combining Jamieson’s expertise with that of the lab. “I’m excited to have someone here who has this kind of wealth of knowledge in her field,” Hunsucker said. “She’ll be able to use her knowledge to help move our research forward and then kind of in return, use our knowledge to help move hers forward.” The Center for Corrosion and Biofouling Control aims to understand and improve corrosion and biofouling control systems. Part of Hunsucker’s research involves evaluating materials that can protect surfaces, such as a ship’s hull, from unwanted growth. She is currently working with the U.S. Navy to see how antifouling techniques perform under different conditions. Jamieson’s research through Flinders’s ARC Training Centre for Biofilm Research & Innovation focuses on the small-scale microorganisms that make up biofilm. She also studies the genetic makeup of microbial communities, which Hunsucker wants to add to her own research. Jamieson is especially interested in learning how antifouling materials interact with local waters. Florida’s seascape is warmer than Australia’s, so fouling grows quicker here than it does there. She also wants to see how American antifouling materials vary from those used in Australia and collaborate on a versatile solution that can withstand a variety of conditions. “Materials that work well here will probably not work in other environments,” Jamieson said. “Seeing how to develop materials for all three environments will be an interesting pathway forward.” Hunsucker hopes this exchange will lead to even more collaboration with Flinders University. “The program that she’s involved with opens the door for collaborative efforts for us to maybe go to Australia in the future,” Hunsucker said. “Her colleagues can also similarly come back and work with us.” Jamieson’s scholarship is funded by the American Australian Association, a New York-based non-profit organization dedicated to deepening and strengthening ties between the United States and Australia. The South Australia Defense, Space and Cyber Scholarship funds scholars from the U.S. and South Australia undertaking Ph.D. or post-doctoral research in those fields. Kelli Hunsucker and Geoffrey Swain are available to speak with media.

Measuring how teachers' emotions can impact student learning
University of Delaware professor Leigh McLean has developed a new tool for measuring teachers’ emotional expressions and studying how these expressions affect their students’ attitudes toward learning. McLean uses this tool to gather new data showing emotional transmission between teachers and their students in fourth-grade classrooms. McLean and co-author Nathan Jones of Boston University share the results of their use of the tool in a new article in Contemporary Educational Psychology. They found that teachers displayed far more positive emotions than negative ones. But they also found that some teachers showed high levels of negative emotions. In these cases, teachers’ expressions of negative emotions were associated with reduced student enjoyment of learning and engagement. These findings add to a compelling body of research highlighting the importance of teachers’ and students’ emotional experiences within the context of teaching and learning. “Anyone who has been in a classroom knows that it is an inherently emotional environment, but we still don’t fully understand exactly how emotions, and especially the teachers’ emotions, work to either support or detract from students’ learning,” said McLean, who studies teachers’ emotions and well-being in the College of Education and Human Development’s School of Education (SOE) and Center Research in Education and Social Policy. “This new tool, and these findings, help us understand these processes more precisely and point to how we might provide emotion-centered classroom supports.” Measuring teacher and student emotions McLean and Jones collected survey data and video-recorded classroom observations from 65 fourth-grade teachers and 805 students in a Southwestern U.S. state. The surveys asked participants to report their emotions and emotion-related experiences — like feelings of enjoyment, worry or boredom — as well as their teaching and learning behaviors in mathematics and English language arts (ELA). Using the new observational tool they developed — the Teacher Affect Coding System — McLean and Jones also assessed teachers’ vocal tones, body posturing, body movements and facial expressions during classroom instruction and categorized outward displays of emotion as positive, negative or neutral. For example, higher-pitched or lilting vocal tones were categorized as positive, while noticeably harsh or sad vocal tones were categorized as negative. Overall, McLean and Jones found that teachers spent most of their instructional time displaying outward positive emotions. Interestingly though, they did not find any associations between these positive emotions and students’ content-related emotions or learning attitudes in ELA or math. “This lack of association might be because outward positivity is the relative ‘norm’ for elementary school teachers, and our data seem to support that,” McLean said. “That’s not to say that teachers’ positivity isn’t important, though. Decades of research has shown us that when teachers are warm, responsive and supportive, and when they foster positive relationships with their students, students do better in almost every way. It could be that positivity works best when done in tandem with other important teacher behaviors or routines, or it could be that it is more relevant for different student outcomes.” However, they did find that a small subset of teachers — about 10% — displayed notable amounts of negative emotions, with some showing negativity during as much as 80% of their instructional time. The students of these teachers reported reduced enjoyment and engagement in their ELA classes and reduced engagement in their math classes. “We think that these teachers are struggling with their real-time emotion regulation skills,” McLean said. “Any teacher, even a very positive one, will tell you that managing a classroom of students is challenging, and staying positive through the frustrating times takes a lot of emotional regulation. Emotion regulation is a particularly important skill for teachers because children inherently look to the social cues of adults in their immediate environment to gauge their level of safety and comfort. When a teacher is dysregulated, their students pick up on this in ways that can detract from learning.” Recommendations for supporting teacher well-being Given the findings of their study, McLean and Jones make several recommendations for teacher preparation and professional learning programs. As a first step, they recommend that teacher preparation and professional learning programs share information about how negative emotions and experiences are a normal part of the teaching experience. As McLean said, “It’s okay to be frustrated!” However, it is also important to be aware that repeated outward displays of negative emotion can impact students. McLean and Jones also suggest that these programs provide specific training to teachers on skills such as mindfulness and emotion regulation to help teachers manage negative emotions while they’re teaching. “Logically, these findings and recommendations make complete sense,” said Steve Amendum, professor and director of CEHD’s SOE, which offers a K-8 teacher education program. “After working with many, many teachers, I often see teachers' enthusiasm or dislike for a particular activity or content area transfer to their students.” McLean and Jones, however, emphasize that supporting teacher well-being can’t just be up to the teachers. Assistant principals, principals and other educational leaders should prioritize teacher wellness across the school and district. If teachers’ negative emotions in the classroom result in part from challenging working conditions or insufficient resources, educational leaders and policymakers should consider system-wide changes and supports to foster teacher well-being.

How the Black Sea ceasefire could backfire for Ukraine
Washington is touting the proposed Black Sea ceasefire between Ukraine and Russia, but there are signs that Russia could emerge from the deal with the upper hand. Hein Goemans, a political science professor at the University of Rochester whose research focuses on territorial disputes and what starts and ends wars, says the agreement “doesn’t really mean much.” “What matters is territorial divisions,” Goemans says. “I see this ceasefire deal as Russia trying to play the United States.” Goemans says the deal would be reasonable if the U.S. were willing to enforce it with sanctions if, or when, Russia reneges. “Ukraine should not believe this deal is in any way credible if the U.S. is not willing to commit to sanctions if Russia reneges, which it will,” Goemans says. He adds that the deal also favors Russia if other parts of it, like the repatriation of Ukrainian children, are not effected. “The chance that Russia would effectively help with the repatriation of Ukrainian abducted children is zero,” Goemans says. “It appears Russia has not compromised on any dimension.” Goemans recently shared similar thoughts with Newsweek, and is regularly tapped by news outlets around the world for his insights on the war in Ukraine and territorial disputes in hotspots across the globe.

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.

The Lost Girls of Autism is published on 3 April 2025, coinciding with Autism Awareness Month in April In the book, Professor Rippon explores the ‘male’ history of autism, and why autism in women has been misunderstood and ignored Professor Rippon will give a free public lecture on the book at Aston University on 6 May 2025. Gina Rippon, professor emeritus of cognitive neuroimaging at Aston University Institute of Health and Neurodevelopment (IHN), has written a new book, entitled The Lost Girls of Autism. The book will be released on 3 April 2025, coinciding with Autism Acceptance Month in April. It has the subtitle ‘How Science Failed Autistic Women and the New Research that’s Changing the Story’. Historically, doctors believed that autism was a male condition, and simply did not look for it in girls and women. This has meant that autistic girls visiting a doctor have been misdiagnosed with anxiety, depression or personality disorders, or are missed altogether. Many women only discover they have the condition when they are much older, missing decades of support. In more recent years, it has become apparent that girls and women with autism have different traits and behaviours to boys and men, and are more likely to hide autistic traits to fit in – known as camouflaging. In The Lost Girls of Autism, Professor Rippon explores the emerging science of female autism, and examines why it has been systematically ignored and misunderstood for so long. Professor Rippon will give a free public lecture about her book on Tuesday 6 May 2025 at 18:00 BST at Aston Business School. Visit https://www.eventbrite.co.uk/e/the-lost-girls-of-autism-an-audience-with-author-gina-rippon-tickets-1304020734119 for more information and tickets. Copies of the book will be on sale at the event. Professor Rippon said: “This book reveals how a ‘male spotlight’ problem has biased many aspects of the autism story, from what autism is, to how we recognise it, and even how brain imagers like me search for answers. It shows how and why autistic women have been unrecognised, overlooked and unsupported. It shines a new light on how the story is changing and how we are now beginning to recognise the full spectrum of the autistic experience. It is for anyone with an interest in autism in all its presentations.”
For autonomous machines to flourish, scalability is everything
The past decade has seen remarkable advancements in robotics and AI technologies, ushering in the era of autonomous machines. While the rise of these machines promises to revolutionize our economy, the reality has fallen short of expectations. That’s not for a lack of intensive investments in research in development, says Yuhao Zhu, an associate professor of computer science at the University of Rochester. The reason we’re not seeing more service robots, autonomous drones, and self-driving vehicles, Zhu says, is that autonomation development is currently scaling with the size of engineering teams rather than the amount of relevant data and computational resources. This limitation prevents the autonomy industry from fully leveraging economies of scale, Zhu says, particularly the exponentially decreasing cost of computing power and the explosion of available data. Zhu recently co-authored a report on the quest for economies of scale in autonomation in Communications of the ACM and is part of an international team of computer scientists focused on making autonomous machines more reliable and less costly.

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
