UD researchers launch open-source tool to boost global food security and water sustainability
Efficient water usage in agriculture is crucial for sustaining a growing human population. A better understanding of the systems that support agriculture, farmers and farmlands allows for food production to become more efficient and prosperous. That's what makes the Monthly Irrigated and Rainfed Cropped Areas Open Source (MIRCA-OS) dataset so important. MIRCA-OS offers high-resolution data on 23 crop classes — including maize, rice and wheat — and helps researchers, students and farmers examine irrigation, rainfall and croplands and how they interact with global water systems. Co-authored by Endalkachew (Endi) Kebede, a doctoral student in University of Delaware’s Department of Geography and Spatial Sciences, a recent paper focused on MIRCA-OS was published in Nature Scientific Data. Kyle Davis, assistant professor in the Department of Geography and Spatial Sciences and the Department of Plant and Soil Sciences, served as a co-author on the paper and coordinated the study. “We first developed a comprehensive data library of crop-specific irrigated and rainfed harvested areas for all countries,” Kebede said. “This involved two years of gathering data from a wide range of international, national and regional sources. Through this process, we produced a tabulated crop calendar, annual harvested area grids and monthly harvested area grids for all irrigated and rainfed crops.” “The amount of effort that Endi put in to gather, process and harmonize all of this data is truly incredible,” Davis said. “His effort is a very important contribution to the scientific and development communities.” Doctoral student Endalkachew Kebede (left) and Assistant Professor Kyle Davis. (Photo credit: University of Delaware) Cropland accounts for 13% of Earth's total habitable land, and the preservation of cropland is important in feeding the growing global population. “Crop production has been a widespread human activity for a few thousand years, and it has a huge role in global food security,” Kebede said. “But it also has unintended impacts on the environment, such as overutilization of water resources, pollution through rivers or the effects on soil and the environment.” MIRCA-OS can play a crucial role in helping to better understand croplands and agriculture, allowing the global population to be successfully fed while minimizing the agricultural effects on the environment. In addition to the data included on cropland and water resources, MIRCA-OS allows researchers to view social aspects like poverty and unemployment through an agricultural lens, creating a better understanding of the interconnectivity of agriculture and social issues. MIRCA-OS is an updated version of the earlier MIRCA2000 dataset. Kebede said the MIRCA2000 was released nearly two decades ago, so renewing the data gives users more accurate and timely information. Both datasets specialized in examining irrigation and rainfall, but the MIRCA-OS added two new complexities to their data. First, MIRCA-OS is open source, meaning it is publicly available for anyone to use, download, or modify. Kebede said the added accessibility allows the technology to contribute to anyone's work, whether it be a student, a researcher or a farmer. “Anybody can use, update it, or upscale it to the special skill they’re interested in,” Kebede said. “Some might use it for research, some might use it to create policies and some might use it to practice agriculture.” To arrange an interview with Davis, visit his profile and click on the contact button.
NASA Asks Researchers to Help Define Trustworthiness in Autonomous Systems
A Florida Tech-led group of researchers was selected to help NASA solve challenges in aviation through its prestigious University Leadership Initiative (ULI) program. Over the next three years, associate professor of computer science and software engineering Siddhartha Bhattacharyya and professor of aviation human factors Meredith Carroll will work to understand the vital role of trust in autonomy. Their project, “Trustworthy Resilient Autonomous Agents for Safe City Transportation in the Evolving New Decade” (TRANSCEND), aims to establish a common framework for engineers and human operators to determine the trustworthiness of machine-learning-enabled autonomous aviation safety systems. Autonomous systems are those that can perform independent tasks without requiring human control. The autonomy of these systems is expected to be enhanced with intelligence gained from machine learning. As a result, intelligence-based software is expected to be increasingly used in airplanes and drones. It may also be utilized in airports and to manage air traffic in the future. Learning-enabled autonomous technology can also act as contingency management when used in safety applications, proactively addressing potential disruptions and unexpected aviation events. TRANSCEND was one of three projects chosen for the latest ULI awards. The others hail from Embry-Riddle Aeronautical University in Daytona Beach – researching continuously updating, self-diagnostic vehicle health management to enhance the safety and reliability of Advanced Air Mobility vehicles – and University of Colorado Boulder – investigating tools for understanding and leveraging the complex communications environment of collaborative, autonomous airspace systems. Florida Tech’s team includes nine faculty members from five universities: Penn State; North Carolina A&T State University; University of Florida; Stanford University; Santa Fe College. It also involves the companies Collins Aerospace in Cedar Rapids, Iowa and ResilienX of Syracuse, New York. Carroll and Bhattacharyya will also involve students throughout the project. Human operators are an essential component of aviation technology – they monitor independent software systems and associated data and intervene when those systems fail. They may include flight crew members, air traffic controllers, maintenance personnel or safety staff monitoring overall system safety. A challenge in implementing independent software is that engineers and operators have different interpretations of what makes a system “trustworthy,” Carroll and Bhattacharyya explained. Engineers who develop autonomous software measure trustworthiness by the system’s ability to perform as designed. Human operators, however, trust and rely on systems to perform as they expect – they want to feel comfortable relying on a system to make an aeronautical decision in flight, such as how to avoid a traffic conflict or a weather event. Sometimes, that reliance won’t align with design specifications. Equally important, operators also need to trust that the software will alert them when it needs a human to take over. This may happen if the algorithm driving the software encounters a scenario it wasn’t trained for. “We are looking at how we can integrate trust from different communities – from human factors, from formal methods, from autonomy, from AI…” Bhattacharyya said. “How do we convey assumptions for trust, from design time to operation, as the intelligent systems are being deployed, so that we can trust them and know when they’re going to fail, especially those that are learning-enabled, meaning they adapt based on machine learning algorithms?” With Bhattacharyya leading the engineering side and Carroll leading the human factors side, the research group will begin bridging the trust gap by integrating theories, principles, methods, measures, visualizations, explainability and practices from different domains – this will build the TRANSCEND framework. Then, they’ll test the framework using a diverse range of tools, flight simulators and intelligent decision-making to demonstrate trustworthiness in practice. This and other data will help them develop a safety case toolkit of guidelines for development processes, recommendations and suggested safety measures for engineers to reference when designing “trustworthy,” learning-enabled autonomous systems. Ultimately, Bhattacharyya and Carroll hope their toolkit will lay the groundwork for a future learning-enabled autonomous systems certification process. “The goal is to combine all our research capabilities and pull together a unified story that outputs unified products to the industry,” Carroll said. “We want products for the industry to utilize when implementing learning-enabled autonomy for more effective safety management systems.” The researchers also plan to use this toolkit to teach future engineers about the nuances of trust in the products they develop. Once developed, they will hold outreach events, such as lectures and camps, for STEM-minded students in the community.

Most companies around the world have a leader, whether that title is a President, CEO, or Founder. There’s almost always someone at the very top of a corporate food chain, and from that position down, the company is structured hierarchically, with multiple levels of leadership supervising other employees. It’s a structure with which most people in the working world are familiar, and it dates back as long as one can remember. The word itself—leader—dates back to as far as the 12th Century and is derived from the Old English word “laedere,” or one who leads. But in 2001, a group of software engineers developed the Agile Workflow Methodology, a project development process that puts a priority on egalitarian teamwork and individual independence in searching for solutions. A number of businesses are trying to embrace a flatter internal structure, like the agile workflow. But is it necessarily the best way to develop business processes? That’s the question posed by researchers, including Goizueta Business School’s Özgecan Koçak, associate professor of organization and management, and fellow researchers Daniel A. Levinthal and Phanish Puranam in their recently published paper on organizational hierarchies. “Realistically, we don’t see a lot of non-hierarchical organizations,” says Koçak. “But there is actually a big push to have less hierarchy in organizations.” Part of it is due to the demotivating effects of working in authoritarian workplaces. People don’t necessarily like to have a boss. We place value in being more egalitarian, more participatory. Özgecan Koçak, Associate Professor of Organization & Management “So there is some push to try and design organizations with flatter hierarchies. That is specifically so in the context of knowledge-based work, and especially in the context of discovery and search.” Decoding Organizational Dynamics While the idea of an egalitarian workplace is attractive to many people, Koçak and her colleagues wanted to know if, or when, hierarchies were actually beneficial to the health of organizations. They developed a computational agent-based model, or simulation, to explore the relationships between structures of influence and organizational adaptation. The groups in the simulation mimicked real business team structures and consisted of two types of teams. In the first type, one agent had influence over the beliefs of rest of the team. For the second type, no one individual had any influence over the beliefs of the team. The hierarchical team vs. the flat structured team. “When you do simulations, you want to make sure that your findings are robust to those kinds of things like the scale of the group, or the how fast the agents are learning and so forth,” says Koçak. What’s innovative about this particular simulation is that all the agents are learning from their environment. They are learning through trial and error. They are trying out different alternatives and finding out their value. Özgecan Koçak Koçak is very clear that the hierarchies in the simulation are not exactly like hierarchies in a business organization. Every agent was purposefully made to be the same without any difference in wisdom or knowledge. “It’s really nothing like the kinds of hierarchies you would see in organizations where there is somebody who has a corner office, or somebody who is has a management title, or somebody’s making more than the others. In the simulation, it’s nothing to do with those distributional aspects or control, and nobody has the ability to control what others do in (the simulation). All control comes through influence of beliefs.” Speed vs. Optimal Solutions What they found in the simulation was that while both teams solved the same problems presented to them, they achieved different results at different speeds. We find that hierarchical teams don’t necessarily find the best solution, but they find the good enough solution in the shorter term. So if you are looking at the really long term, crowds do better. The crowds where individuals are all learning separately, they find the best solution in the long run, even though they are not learning from each other. Özgecan Koçak Özgecan Koçak (pronounced as ohz-gay-john ko-chuck) is associate professor of Organization & Management at Emory University’s Goizueta Business School. She holds a Ph.D. in organizational behavior from the Graduate School of Business at Stanford University. For example, teams of scientists looking for cures or innovative treatments for diseases work best with a flat structure. Each individual works on their own timeline, with their own search methodologies. The team only comes together for status updates or to discuss their projects without necessarily getting influence or direction from colleagues. The long-term success of the result is more important in some cases than the speed at which they arrive to their conclusion. That won’t work for an organization that answers to a board of directors or shareholders. Such parties want to see rapid results that will quickly impact the bottom line of the company. This is why the agile methodology is not beneficial to large-scale corporations. Koçak says, “When you try to think about an entire organization, not just teams, it gets more complicated. If you have many people in an organization, you can’t have everybody just be on the same team. And then you have to worry about how to coordinate the efforts of multiple teams. That’s the big question for scaling up agile. We know that the agile methodology works pretty well at the team level. However, when firms try to scale it up applied to the entire organization, then you have more coordination problems. Özgecan Koçak “You need some way to coordinate the efforts with multiple teams.” The Catch: Compensation Makes a Difference The simulation did not take into account one of the biggest parts of a corporate hierarchical structure—incentives and reward. The teams in the simulation received no monetary compensation for their leadership or influence. That is not something that happens in real life. Koçak says, “If you built up an organization with just influence, you just say we’re not going to have any authority, and we’re not going to give anybody the right to control anybody else’s actions. If we’re not going to be rewarding anyone more than the other, there’s not going to be any marks of status, etc. We’re just going to have some people influence others more. I would guess that would automatically lead to a prestige hierarchy right away. The person with more influence, you would start respecting more.” It’s almost like we’re incapable of working in a flat society, because somebody always wants to be or naturally becomes a leader and an influencer whether they planned on it or not. Özgecan Koçak The paper concludes that both methodologies, with either hierarchical and flat organization of teams, reach their goals. They just arrive at different times with different end results. If an organization has the luxury of time and money, a flat, agile methodology organization might be the right structure for that company. However, even agile workflow needs some coordination, according to Koçak. “There are also some search tasks that require coordination. You can’t always be searching on your own independently of others. There are some situations in which search needs to be done in a coordinated fashion by more than one person in teams. That’s because many of the knowledge-based settings where we do discovery require some division of labor, some specialization by expertise.” Communication is Key The key to any successful workflow, whether it be agile or hierarchical, is coordination and communication. Looking back to the example of scientific researchers, Koçak said, “You have scientific teams working independently of one another without a common boss dictating what they do research on or how they do it. Instead, they explore and experiment on their own. They write up their results, share their results, and learn from each other, because they are in the long-term game. The goal is to find the truth, however long it takes. “But when you look closely at a scientific team where everybody’s exploring, there is still some need for coordination. A lot of that happens through communication, and a lot of times projects will have a lead. Not necessarily somebody who knows better than the others, but somebody who’s going to help with coordination.” The leaner, flatter organizational structures in businesses might be gaining popularity. This simulation done by Koçak and colleagues, however, shows that it isn’t a perfect fit for every company, Further, some form of hierarchical workflow is necessary to maintain communication and coordination. Hierarchical structures don’t always find the best solution to a problem, but it’s almost always a good solution in a timelier fashion. Looking to know more?

Retro Appeal: Research Reveals the Reasons Behind Vintage Shopping in Turbulent Times
Why buy vintage? Reasons abound. It’s kinder to the environment. It’s usually cheaper. It’s back in style. But did you know it may also address a deep-seated psychological need for stability amid upheavals? Vintage consumption—that is, buying previously owned items from an earlier era—acts as a means to connect the past, present, and future. That connection across time can be reassuring, most especially in times of uncertainty. When you really want to buy a leather jacket that’s older than you are, it may be enlightening to consider the circumstances. This vintage insight reveals itself in research by Ryan Hamilton, associate professor of marketing at Goizueta Business School. In an award-winning article titled “Stitching time: Vintage consumption connects the past, present, and future,” Hamilton—along with coauthors Gulen Sarial-Abi, Kathleen Vohs, and Aulona Ulqinaku—uncovered why we may want to turn to something old when we perceive threats to our worldviews. Notably, multiple studies have shown thoughts of death to increase the appeal of items that have already stood the test of time. The Psychological Appeal of Thrifting In psychology, “meaning frameworks” are how we, as human beings, interpret and understand our lives as meaningful and valuable. Threats to our meaning frameworks—i.e., the pillars propping up our worldviews—can include thoughts of death, unsettling economic upheavals, and other existential challenges. In order to explore the effects of meaning threats on our preference for vintage, Hamilton and coauthors designed several studies. Their pilot test measured the physical health of nursing home residents. It then measured their preferences for vintage items, controlling for other variables. The results held up the researchers’ hypothesis: Vintage items—be they books, watches, bicycles, or luggage—were more strongly preferred over their modern versions by elderly participants in poorer health, presumably those most likely to have mortality on their minds. Six subsequent studies used different variables to see if the main hypothesis continued to hold up. It did, while at the same time revealing more information about the mechanisms at work. Ryan Hamilton Associate Professor of Marketing Death or Dental Pain In one study, for example, researchers prompted participants with death reminders. They had to contemplate and write about their own deaths to make sure mortality was top of mind. Researchers prompted a control group with reminders of dental pain. Both groups then answered a 12-question survey about their desire for structure (e.g., set routines and practices) at that particular moment. But there was another element in this study: contemplating wearing a watch from the 1950s. As predicted by the main hypothesis, death cues were associated with participants reporting that they desired more structure. The only exceptions was for those who imagined an old watch ticking on their wrists. Vintage consumption seemed to act as a buffer against unsettling thoughts of death for them. What is going on here? As noted above, the researchers theorize and show that vintage objects tend to connect our thoughts of the past, present, and future. These mental, intertemporal connections tend to be reassuring—“a hidden factor” in our preferences and choices, as Hamilton notes. More than Nostalgia One might think nostalgia—a sentimental longing for the past—could also be at work. Feeling nostalgic for one’s own past and social connections can buffer against meaning threats, as previous research has shown. But this paper was designed to tease out nostalgia. It focused on vintage’s connections across time regardless of one’s personal experiences. “This study allowed us to clearly show that people respond differently to something they believe to be old,” as Hamilton explains. “It’s not just something that has a retro look, which was one of my favorite aspects of this project.” Hamilton and his coauthors achieved this by having participants evaluate identical items thought to be genuinely vintage or replicas. And the results were robust. Retro replicas, which can prompt nostalgia, did not have the same psychological impact as items believed to be genuinely old. For instance, 20-year-olds who find a watch from the 1950s reassuring can’t feel nostalgic about the design personally. They can, however, feel a connection across time—and that came through in the study. Retail Therapy on the Rise? Hamilton’s research here follows his broader interest in consumer psychology, branding, and decision-making. “When we’re buying things, we may think it’s based on strict utility maximization. However, it also might be making us feel better in some way,” says Hamilton. Shopping can serve as an emotional management strategy—for better or for worse. Although it was outside the scope of this particular investigation (and all participants were over age 18), the insights gleaned here may help explain why 21st-century teenagers seem to be particularly avid “thrifters” these days. “I don’t want to overstate our findings. But it’s at least possible that the appeal of vintage for teenagers is boltstered by a sense of permanence and endurance that helps them during times of upheaval,” Hamilton says. It turns out a 30-year-old leather jacket might help its new owner feel better on many levels. So is it any wonder that vintage shopping is surging in uncertain times? Fashion magazines, such as Vogue and GQ, are following the vintage craze closely in 2024. Concern for climate change and the Earth’s finite resources may present two intertwined reasons to buy old things: those two things are environmental and psychological. If tumultuous times continue amid contentious elections, wars, and other threats, it seems safe to bet on vintage.

Springtime swarms: What you need to know about termite alates
As temperatures warm up across Louisiana, so does termite activity. Homeowners may soon begin to notice large swarms of winged insects in and around their homes. These are termite alates, also known as swarming termites. “Swarming is how termites establish new colonies,” said LSU AgCenter entomologist Aaron Ashbrook. “Seeing swarms around your home doesn’t necessarily mean you have an infestation, but it does mean termites are nearby.” Alates are the reproductive members of a future termite colony if they can successfully establish. Each spring, usually following a warm rain, these termites leave their established colonies to find new places to nest. Many alates are produced because a low percentage of them are able to establish a colony. After swarming, they shed their wings and pair off to begin new colonies, which is how they end up in homes. Louisiana’s warm, humid climate makes it an ideal environment for termites, especially the Formosan subterranean termite, one of the most destructive species in the United States. Termites can silently cause thousands of dollars in damage before homeowners know they’re there. Tips for homeowners: Don’t panic, but don’t ignore it. Seeing swarms outside is common, but if they're inside your home, call a licensed pest control professional. Look for signs. Discarded wings, mud tubes, water stains, moisture buildup, and soft or hollow-sounding wood can all indicate a problem. Reduce moisture. Termites thrive in damp environments and require moist wood to attack structures. Fix leaks and ensure proper drainage around your home. Schedule regular inspections. Annual termite inspections are recommended, especially in high-risk areas like Louisiana. “Termites can cause extensive structural damage to your home that may go unnoticed,” said Carol Friedland, director of LaHouse Research and Education Center. “Early detection and prevention can save homeowners a lot of stress and money.” The LSU AgCenter’s Department of Entomology and LaHouse Research and Education Center provide research-based guidance to help Louisiana residents protect their homes from termites and other structural pests.

The roots of scuba diving lie in exploration. But in an age when advanced instruments can drive research, too, why not stay dry on land? Researchers have used scuba diving as a tool for decades, but as technology evolves, remotely operated vehicles (ROVs) can aid, and sometimes replace, divers in the research process. Still, argues Stephen Wood, no existing tools have the full capability of a human. The professor of ocean engineering says the ability to grab items or quickly turn one’s head is difficult to replicate in an ROV. He also argues that although robots can collect and send data, the ability to assess and interpret an environment through a human lens is essential. “The human cannot leave” the research, Wood says. The American Academy of Underwater Sciences (AAUS) defines scientific diving as “diving performed solely as a necessary part of a scientific, research, or educational activity by employees whose sole purpose for diving is to perform scientific research tasks.” With more than 140 organizational members, AAUS supports diving as a research tool and protects scientific divers’ health and safety. Researchers and students must obtain an AAUS certification, which Florida Tech offers, before undertaking a scientific dive. At Florida Tech, any diver who plans to use compressed air or air blends for activity involving teaching or research must comply with AAUS. Robert van Woesik, professor of marine sciences, studies the dynamics of coral reefs worldwide. He and his students scuba dive to examine and photograph coral assemblages, then return with information they can use to predict the impact of local and global disturbances, recovery from disturbances and future growth. The ability to personally identify different species underwater is crucial to understanding coral reef dynamics. He says that without scuba, the necessary training to develop that skill falls away. “I think it’s still worthwhile knowing the species composition of a reef underwater instead of just saying, ‘Okay, we don’t need scuba divers anymore. We just need photographs and ROVs,’” van Woesik says. He learns the most when he can descend to a reef and see the seascape himself. “I think there’s something to be said to just go in the water and ask some questions,” van Woesik says. “That’s the valuable part of being able to scuba dive, getting amongst it to experience the reef, in tandem with analyzing photographs from around the world on the computer.” Assistant professor of marine sciences Austin Fox says in his research in the Indian River Lagoon, diving is essential for operating—and sometimes finding—instruments. “We spend a lot of time trying to figure out ways to do this stuff without diving…but there’s just no replacement for it.” Austin fox, Assistant professor of marine sciences Scientific diving has taken Florida Tech researchers across the globe, from the murky floor of the Indian River Lagoon to the depths of Antarctica’s McMurdo Sound. Rich Aronson, department head and professor of ocean engineering and marine sciences, studies coral reefs in the tropics and subtidal communities in Antarctica. In 1997, he had the opportunity to visit the McMurdo Station to study invertebrate ecology—specifically, who eats what and whether they leave traces of their predatory activity on the shells of their prey. There, he completed 27 dives of up to 130 feet deep. Some were done through ice-cracks in remote areas, he recalls, whereas others were from holes drilled through 10 feet of sea-ice. He noted that the time to prepare for these dives was extensive—two 30-minute dives took eight hours—and they weren’t without risk. “That was the first and only time I’ve dived under the ice. It’s dangerous because there’s a ceiling above you,” Aronson says. “You jump in the hole and try not to screw it up because if you screw it up, you’re dead.” Though risky, Aronson says scuba diving was crucial to the research. He argues that neither ROVs nor oceanographic sensors could have collected or sampled organisms at fine scales, run transects and made behavioral observations like a human could. Additionally, he says his observations at depth, such as the “sting of subzero water” on his face and “the slowness of reaction of the animals living down there,” are what later inspired a project of his combining deep-sea oceanography and paleontology to project the future of Antarctic seafloor communities in a rapidly warming world. “Science is a lot more subjective than you might think, and feeling the environment helps you understand it.” Richard Aronson, department head and professor of marine sciences The risky nature of scuba diving is why programs like AAUS exist: to standardize safe and responsible diving practices for conducting scientific research. Divers are at risk for a number of pressure-related injuries, such as decompression sickness: a condition in which residual nitrogen can create bubbles in the blood and body tissue upon ascent if the diver rises to the surface too fast. To reduce their risk, divers must plan and track how deep they are going, the time at which they are that depth (and subsequent depths) and how long they need to wait before changing depth. Technology has also evolved since the beginning of scuba to support divers’ safety further. Digital dive computers, developed in the 1980s, help divers estimate how long they can stay at their current depth while underwater (among other things). Additionally, Enriched Air Nitrox (Nitrox) is a gas mixture that contains a higher percentage of oxygen than standard air. Divers who use Nitrox can extend their time at depth and reduce their risk of decompression sickness because of its reduced nitrogen pressure. Van Woesik predicts that dive technology will keep evolving. He imagines there could soon be a system that allows divers to upload data at depth, and a system that aids in species identification without having to decipher an image at the surface. He also believes that innovators will keep working to reduce hazards and prioritize safety, because despite the risks, divers will always get in the water. “Hopefully that technology will get better so we can go deeper, safer, and so we can stay down a bit longer to explore and further understand the natural wonders of the oceans,” van Woesik says.

From Saver to Spender: Navigating the Retirement Mindset Shift
Let’s start with a familiar—and slightly ridiculous—scene: a retired couple with $750,000 safely tucked away in investments, quietly nibbling no-name tuna on toast while muttering, “We just can’t afford steak anymore.” Sound absurd? Sadly, it’s not fiction. Despite having ample savings, many retirees live with perpetual financial anxiety, clinging to their nest egg as if it were their last roll of toilet paper during a pandemic. Meanwhile, they try to survive solely on government pensions, making life unnecessarily stressful and, let’s face it, a bit joyless. I've wrestled with this as someone who entered retirement earlier than expected. Years in finance taught me how to budget, invest, and plan, but transitioning from saving to spending required a whole new mindset. I learned quickly that being financially “prepared” doesn’t mean you’re emotionally or psychologically ready to spend. So, what’s going on here? The Hypothesis: Individuals Prefer Spending Income Rather Than Saving Retirees prefer spending income (pensions or annuities) rather than withdrawing from savings or investment accounts. This isn’t just a quirky behavioural trend—it’s a deeply ingrained bias, and neuroscience supports it. Research by Michael S. Finke, a professor at The American College and noted researcher in retirement economics, revealed that retirees tend to spend most of their guaranteed income but only withdraw about half of their savings. In his words: “Retirees spend lifetime income, not savings.” The implication is clear: it’s not about how much money you have but how it feels to use it. This is partly due to what behavioral economists call “mental accounting.” We categorize our money into imaginary buckets: income is for spending, and savings are for safekeeping. Unfortunately, this can lead to financially irrational and highly risk-averse behaviors, such as eating cat food while having six figures in a TFSA. The Neuroscience of Spending Fear Add a little neuroscience, and the story deepens. As we age, changes in the brain, particularly in the prefrontal cortex, can affect how we assess risk and manage uncertainty. This can lead to: • Increased loss aversion: We more acutely feel the pain of spending or loss. • Decision paralysis: We delay or avoid withdrawals, even when reasonable. • Heightened anxiety about the future: We fear running out more than we enjoy spending in the present. This Fear of Running Out (FORO), which I’ve written about in a previous post, keeps many retirees in a defensive crouch, emotionally hoarding their savings rather than using them to enrich the years they worked so hard to reach. It’s no wonder money stress impacts us so deeply—our brains are wired that way. From an evolutionary perspective, our minds are designed to fear scarcity because running out of resources once posed a real danger. When we perceive that threat today, whether it’s a dip in our investments or rising grocery bills, our brain shifts into fight-or-flight mode and begins releasing cortisol—the stress hormone that heightens our anxiety. Then our amygdala, that little alarm system in our brain designed to protect us from danger, can’t differentiate between a financial crisis and a sabre-toothed tiger. So, it reacts similarly, nudging us toward quick, often irrational decisions. Sometimes that means freezing and doing nothing; other times, it leads to panicking and regretful choices. Understanding how our brains function under financial stress allows us to step back, breathe, and make better, calmer decisions—ones that serve us, not scare us. Retirement can be wonderfully freeing—no more commutes, no more meetings—but let’s be honest: it also comes with a significant shift in financial responsibility. Without that steady paycheck, it’s completely normal to feel uneasy about how you'll manage your money, especially when unexpected expenses arise. Sure, there are mindset tools and mental prep strategies that can help ease that existential “What now?” feeling before retirement. But let’s be specific—here are the real, concrete financial stressors that keep many retirees awake at night: • Not Enough Income: One of the biggest fears? Your savings won’t stretch far enough to support the life you want—or handle surprises. • Healthcare Costs: As we age, medical expenses climb. It’s not just the big stuff, either. Even prescriptions and dental bills can blow a hole in your budget. • Market Ups and Downs: A stock market dip can uniquely affect retirees. Observing your investments fluctuate can cause genuine anxiety regarding your income, especially in today’s “trade war” environment. • Inflation: We all feel it. The gradual rise of higher prices erodes your purchasing power, making that carefully saved nest egg feel less secure. • Living Longer Than Planned: It's both a blessing and a challenge. If you're healthy and living well into your 90s (and many do), the big question becomes: will your money last as long as you do? Here’s the good news: when you acknowledge these risks and build a plan around them, you exchange fear for control. And with power comes clarity, confidence, and significantly less stress. That’s when you can truly enjoy retirement—on your terms. How to Flip the Script: Make Savings Feel Like Income So, how can retirees overcome this psychological hurdle? Here are 3 powerful strategies: 1. Create Artificial Income Streams Turn a portion of your savings into predictable, automatic income. This could mean: • Setting up regular monthly withdrawals from an RRIF • Purchasing an annuity • Utilizing a bucket strategy, in which one portion of savings is maintained in a cash-like account to replicate a paycheck When money shows up like a salary, you’re more likely to feel permission to spend it. 2. Use Home Equity as a Back-Up Income Source A secured line of credit (HELOC) or a reverse mortgage can serve as a “Plan B” or income buffer. Knowing that the funds are available can alleviate anxiety, whether you use them or not. 3. Involve Family in Income Planning Sometimes, the best way to reframe a spending decision is through conversation. Adult children or trusted advisors can help develop a spending strategy that feels both secure and reasonable. Families can be invaluable in helping you design: • Emergency funding plans for unexpected expenses like healthcare • Gifting strategies (Want to help the kids or grandkids? Do it while you’re alive to see the joy!) • Income simulations replacing a regular paycheck Open conversations can also help uncover mismatched expectations. For instance, some older adults worry that spending their savings will leave less of an inheritance for their children, which might cause disappointment. But in many cases, their children would much rather see their parents use that money to care for themselves and enjoy their retirement years. The great irony of retirement? The hardest part isn’t building wealth; it’s allowing yourself to enjoy it. So, let’s retire the notion that frugality is forever. Replace the guilt of spending with the confidence of an income strategy. And if you're facing your savings with trepidation, remember: cat food may be a pantry staple for your pet, but it’s no reward for 40 years of hard work. Retirement isn't merely a financial phase—it’s a shift in mindset. That shift begins when we stop hoarding and start living.
BATON ROUGE – Since the Big Bang, the early universe had hydrogen, helium, and a scant amount of lithium. Later, some heavier elements, including iron, were forged in stars. But one of the biggest mysteries in astrophysics is: How did the first elements heavier than iron, such as gold, get created and distributed throughout the universe? A new answer has come from an unexpected place – magnetars. Neutron stars are the collapsed cores of stars that have exploded. They are so dense that one teaspoon of neutron star material, on Earth, would weigh as much as a billion tons. A magnetar is a neutron star with an extremely powerful magnetic field. On rare occasions, magnetars release an enormous amount of high-energy radiation when they undergo “starquakes,” which, like earthquakes, fracture the neutron star’s crust. Starquakes may also be associated with powerful bursts of radiation called magnetar giant flares, which can even affect Earth’s atmosphere. Only three magnetar giant flares have been observed in the Milky Way and the nearby Large Magellanic Cloud, and seven from other nearby galaxies. Astrophysicist Eric Burns and his team of researchers at Louisiana State University in Baton Rouge study magnetars extensively through the observation of gamma-rays. These are the most energetic photons, most famous for turning Bruce Banner into the Incredible Hulk. Burns joined with researchers at Columbia University and other institutions to see if we could use gamma-rays to understand if magnetar giant flares forge the heaviest elements, and unexpectedly found the smoking-gun signature in decades-old data. The study, led by Anirudh Patel, a doctoral student at Columbia University in New York, is published in The Astrophysical Journal Letters. “It’s answering one of the questions of the century and solving a mystery using archival data that people had just forgotten about, demonstrating something that occurred when the Universe was younger,” said Burns. “Giant flares should occur just after the first stars died, meaning we have identified what could be the origin of the first gold in the universe.” How could gold be made at a magnetar? Patel and colleagues, including his advisor Brian Metzger, Professor at Columbia University and senior research scientist at the Flatiron Institute in New York, have been thinking about how radiation from giant flares could correspond to heavy elements forming there. This would happen through a “rapid process” of neutrons forging lighter atomic nuclei into heavier ones. Protons define the element’s identity on the periodic table: hydrogen has 1 proton, helium has 2, lithium has 3, and so on. Atoms also have neutrons which do not affect identity, but do add mass. Sometimes when an atom captures an extra neutron the atom becomes unstable and a nuclear decay process happens that converts a neutron into a proton, moving the atom forward on the periodic table. This is how, for example, a gold atom could take on an extra neutron and then transform into mercury. In the unique environment of a disrupted neutron star, in which the density of neutrons is extremely high, something even stranger happens: single atoms can rapidly capture so many neutrons that they undergo multiple decays, leading to the creation of a much heavier element like uranium. When astronomers observed the collision of two neutron stars in 2017 using NASA telescopes and the gravitational wave observatory LIGO, they confirmed that this event could have created gold, platinum, and other heavy elements. “LIGO tells us there was a merger of compact objects, and Fermi tells us there was a short gamma-ray burst. Together, we know that what we observed was the merging of two neutron stars, dramatically confirming the relationship,” said Burns. But neutron star mergers happen too late in the universe’s history to explain the earliest gold and other heavy elements. Finding secrets in old data At first, Metzger and colleagues thought that the easiest signature to study from the creation and distribution of heavy elements at a magnetar would appear in the visible and ultraviolet light, and published their predictions. But Burns in Louisiana wondered if there could be a gamma ray signal bright enough to be detected, too. He asked Metzger and Patel to work out what that signal could look like. Burns looked up the gamma ray data from the last giant flare that was observed, which was in December 2004. He realized that while scientists had explained the beginning of the outburst, they had also identified a smaller signal from the magnetar, in data from ESA (European Space Agency)’s INTEGRAL, a retired mission with NASA contributions. “It was noted at the time, but nobody had any conception of what it could be,” Burns said. Metzger remembers that Burns thought he and Patel were “pulling his leg” because the prediction from their team’s model so closely matched the mystery signal in the 2004 data. In other words, the gamma ray signal detected over 20 years ago corresponded to what thought it should look like when heavy elements are created and then distributed in a magnetar giant flare. "This is my favorite discovery I've contributed to,” said Burns. “My colleagues found this signal in the past, but nobody knew what it could be at the time. Once these models were ready, everything fit like a perfect puzzle, which is extremely rare in science." Researchers supported their conclusion using data from two NASA heliophysics missions: the retired RHESSI (Reuven Ramaty High Energy Solar Spectroscopic Imager) and the ongoing NASA Wind satellite, which had also observed the magnetar giant flare. Other collaborators on the new study included Jared Goldberg at the Flatiron Institute. Next steps in the magnetar gold rush Patel’s study estimates that magnetar giant flares could contribute about 10% of the total abundance of elements heavier than iron in the galaxy. Since magnetars existed relatively early in the history of the universe, the first gold could have been created this way. LSU PhD candidate Aaron Trigg, a NASA FINESST (Future Investigators in NASA Earth and Space Science and Technology) fellow, who works with Burns, is responsible for finding more magnetar giant flares to study. “These are gargantuan outbursts of energy from the strongest magnets in the Universe, which are powerful enough to affect Earth’s atmosphere,” said Burns. Trigg’s work will help us better understand these sources.” NASA’s forthcoming COSI (Compton Spectrometer and Imager) mission can follow up on these results. COSI, a wide-field gamma ray telescope, is expected to launch in 2027 and will study energetic phenomena in the cosmos, such as magnetar giant flares. COSI will be able to identify individual elements created in these events, providing a new advancement in understanding the origin of the elements. LSU is one of the lead science institutes for COSI. Burns and LSU Assistant Professor Michela Negro have key responsibilities in the mission, and Trigg is working through how best to study giant flares with COSI. These LSU astrophysicists will be growing their research group as they approach launch in 2027. “I have so many questions about the cosmos and our place in it,” said Trigg. “This research allows me to explore those questions and share the answers with the world.”
An Expert Guide to the Papacy and Pope Francis
The death of Pope Francis marks a pivotal moment for the Catholic Church, ending a papacy that redefined the Church's relationship with the modern world. As the College of Cardinals prepares to gather in conclave, Catholics across the globe are closely watching to see whether the next pontiff will build upon Francis' legacy or chart a new course. The following experts are available to provide insight into a range of related topics, including Pope Francis' enduring impact and what lies ahead for the world's 1.4 billion Catholics: Massimo Faggioli, PhD Professor, Theology and Religious Studies Dr. Massimo Faggioli is a world-renowned expert on the history and administrative inner workings of the Catholic Church, with specific expertise in the papacy, Vatican II, the Roman Curia, liturgical reform, new Catholic movements and Catholicism and global politics. As quoted on NPR: "Historically, we see in different conclaves a certain swinging of the pendulum. What the conclave and the next pope cannot do is to ignore and deny the changing features of global Catholicism, which is much less European, much less white, less North American and more Global South..." Kevin Hughes, PhD Chair, Theology and Religious Studies Dr. Kevin Hughes is a leading historical theologian, offering insights into the life, legacy and impact of Pope Francis. He can also speak to the significance of the Pope in Catholicism and the influence of his teachings on the global Catholic Church. As quoted on Scripps News: "[Pope Francis' selection] was really the Church extending beyond the limits of its European imagination. His Latin American identity was really crucial to embracing a new moment within the Church and opening the door in so many ways, and I think he bore witness to that throughout his papacy." Jaisy Joseph, PhD Assistant Professor, Systematic and Constructive Theology Dr. Jaisy Joseph is a trained ecclesiologist, able to address a wide range of topics relating to the papacy, conclave process and Catholic Church. Previously, she has commented on the Church's presence in Asia and the Global South, offering expert commentary on its growth, challenges and shifting influence. As quoted by ABC News Digital: "[The election of someone from the Global South would be] a move in that direction of how to be a global church. That move from a Eurocentric church to a truly global church—I think that's what Francis really inaugurated." Patrick Brennan, JD Professor of Law; John F. Scarpa Chair in Catholic Legal Studies Professor Patrick Brennan is an expert on the conclave process and the main rules that govern it. He can also speak to topics such as the contemporary and historical importance of secrecy in the conclave, what the cardinals may be looking for in the next Pope and the factors that cause similarities and differences from one conclave to the next. As quoted on Fox 29's Good Day Philadelphia: "The purpose of the general congregation is for the cardinals, who don't know each other in some cases, to get to know each other better as they learn about the current state of the Church and together decide on the needs of the Church and priorities for the new pontificate." Brett Grainger, ThD Associate Professor, Study of Spirituality and American Religious History Dr. Brett Grainger is a go-to source for discussions of the changing face and role of modern spirituality in America. He serves as an expert on contemporary religious trends and can also speak to the broader public reaction to Pope Francis' passing, especially outside of the Catholic faith. As quoted by Courthouse News Service: "People are disaffiliating from a tradition—that doesn't necessarily mean in fact that they don't believe in God anymore...What's more important is 'Is this giving me life? Is this making my life more meaningful? Is this giving me the kind of energy and purpose that I'm looking for?' That's where religion is going." Michael Moreland, JD, PhD Professor of Law and Religion; Director, Eleanor H. McCullen Center for Law, Religion and Public Policy Dr. Michael Moreland is a renowned scholar of constitutional law, religious freedom, public policy and ethics. He can provide expert commentary on items related to the Catholic right and the state of religious politics in the United States. As featured on NBC News Digital: Michael Moreland said the mass appeal of "Conclave" captured how, even in a secular modern age, there is still pervasive intrigue around "the ancient rituals of the Catholic Church." "The significance of the theological and spiritual aspects of Catholicism and this process of electing a pope was kind of reduced into partisan politics," he said. Ilia Delio, OSF, PhD Josephine C. Connelly Endowed Chair in Christian Theology Sister Ilia Delio addresses topics in her work such as theology and evolution, technology and human becoming and understandings of Catholicity in a world of complexity. She can provide expert insight into Laudato si', Pope Francis' position on the environment, the relationship between science and religion and integral ecology. As featured in the National Catholic Reporter: "We are clearly an Earth in crisis," with a reversal necessary to secure a sustainable future, said Ilia Delio... Delio posed a series of questions: about the relationship between religion and science; what Laudato si', and Christianity more broadly, can offer ecological movements; and whether the concept of kinship or creation as family might better reflect humanity's place within nature than "care for creation."
